Fulltext Demographic and Socioeconomic Factors Influencing Public Attitudes Toward a Presumed Consent System for Organ Donation Without and With a Priority Allocation Scheme

Tumin M, Tafran K, Mutalib MA, Satar NM, Said SM, Adnan WA, et al.

Medicine (Baltimore), 2015 Oct;94(42):e1713.
PMID: 26496282 DOI: 10.1097/MD.0000000000001713

The influence of demographic and socioeconomic factors on the public's attitude towards a presumed consent system (PCS) of organ donation was estimated in 2 scenarios: without and with a priority allocation scheme (PAS). Self-administered questionnaires were completed by 775 respondents. Using multiple logistic regressions, respondents' objections to donating organs in both scenarios were estimated. In total, 63.9% of respondents would object to donating under a PCS, whereas 54.6% would object under a PCS with a PAS. Respondents with pretertiary education were more likely to object than were respondents with tertiary education, in both the first (adjusted odds ratio [AOR] = 1.615) and second (AOR = 1.728) scenarios. Young respondents were less likely to object than were middle-aged respondents, in both the first (AOR = 0.648) and second (AOR = 0.572) scenarios. Respondents with mid-ranged personal monthly income were more likely to object than were respondents with low income, in both the first (AOR = 1.994) and second (AOR = 1.519) scenarios. It does not seem that Malaysia is ready to implement a PCS. The educational level, age, and income of the broader public should be considered if a PCS, without or with a PAS, is planned for implementation in Malaysia.

INTRODUCTION: Medical products transportation has become an important research topic requiring multidisciplinary collaboration among experts in medicine, engineering, and health economics. Current modes of transportation are unable to overcome the limited settings in maternal healthcare, particularly during the event of obstetric emergencies. The drone is a promising medical product aerial transportation (MedART) that holds an enormous potential for delivery of medical supplies in the healthcare system. We conducted a systematic review to examine scientific evidence of positive impact of drone transportation on maternal health.
METHODS: The following electronic databases were searched from inception to July 2019: ScienceDirect, PubMed, and EMBASE. The report was made in accordance with the principles of PRISMA guidelines. The search terms used were related to drones including unmanned aerial vehicle (UAV) and unmanned aerial system (UAS), and related to obstetric/maternal including obstetric emergencies and postpartum hemorrhage. Studies were selected if the intervention used were drones, and if any direct or indirect maternal health indicators were reported. Meta-analysis was not done throughout the study in view of the anticipated heterogeneity of each study.
RESULTS: Our initial search yielded a total of 244 relevant publications, from which 236 were carried forward for a title and abstract screening. After careful examination, only two were included for systematic synthesis. Among the reasons for exclusion were irrelevance to maternal health purpose, and irrelevance to drone applications in healthcare. An updated search yielded one additional study that was also included. Overall, two studies assessed drones for blood products delivery, and one study used drones to transport blood samples.
CONCLUSION: A significant deficiency was found in the number of reported studies analyzing mode of medical products transportation and adaptation of drones in maternal healthcare. Future drone research framework should focus on maternal healthcare-specific drone applications in order to reap benefits in this area.

Engaging students in active learning lies at the center of effective higher education. In medical schools, students' engagement in learning and research has come under increasing attention. The objective of this study was to synthesize evidence on medical students' perspectives on the engagement in research. We performed a systematic review and meta-analysis. Relevant studies were searched in electronic databases. The methodological quality of the included studies was assessed. Overall, 14 observational studies (with 17 data sets) were included. In general, many studies did not use the same questionnaires and the outcome measurements were not consistently reported; these presented some difficulties in pooling the results. Whenever data permitted, we performed pooled analysis for the 4 education outcomes. A Bayesian meta-analytical approach was supplemented as a measure of uncertainty. A pooled analysis showed that 74% (95% confidence interval [CI]: 1.57%-11.07%; I2: 95.2%) of those students who engaged in research (while at the medical school) had positive attitudes toward their research experiences, whereas 49.5% (95% CI: 36.4%-62.7%; I2: 93.4%) had positive attitudes toward the study of medical sciences, 62.3% (95% CI: 46.7%-77.9%; I2: 96.3%) had self-reported changes in their practices, and 64% (95% CI: 30.8%-96.6%; I2: 98.5%) could have published their work. There was substantial heterogeneity among studies. We acknowledged the caveats and the merit of the current review. Findings showed that engagement in research resulted in favorable reactions toward research and academic learning. Future well-designed studies using standardized research tools on how to engage students in research are recommended.

Jaiswal V, Mukherjee D, Batra N, Ruchika F, Susheela AT, Chia JE, et al.

Medicine (Baltimore), 2022 Jul 01;101(26):e29822.
PMID: 35777067 DOI: 10.1097/MD.0000000000029822

BACKGROUND: Cannabis use has been steadily rising in the United States and can have multiple adverse effects, including cannabis-induced acute pancreatitis. This study aims to collate and highlight the significant demographics, clinical presentation, and outcomes in patients with cannabis-induced acute pancreatitis.
METHOD: A systematic literature search of electronic databases for peer-reviewed articles was conducted. After an initial search, we found 792 articles through different electronic databases. After manually removing duplicates and articles that did not meet the criteria, 25 articles were included in our review.
RESULTS: A total of 45 patients were studied, 35 (78%) cases were male and 10 (22%) cases were female, showing male predominance. The mean age of all participants was 29.2 ± 10.3 years. The most common presenting symptoms were abdominal pain 21 of 21 (100%), nausea 17 of 21 (81%), and vomiting 12 of 20 (60%). Ultrasound was normal in the majority of patients, with findings of mild pancreatitis. Computerized tomography scans revealed pancreatic edema and inflammation in 7 of 20 (35%) patients, and findings of necrotizing pancreatitis and complex fluid collection were visualized in 3 of 20 (15%) patients. Dilatation of intrahepatic or extrahepatic biliary ducts was not seen in any patients. The overall prognosis was good, with reported full recovery.
CONCLUSIONS: Cannabis should be included in the differential diagnosis for the etiology of acute pancreatitis, which would help in early intervention and treatment for the mitigation of the rapidly progressive disease.
Fulltext The effectiveness of culturally tailored video narratives on medication understanding and use self-efficacy among stroke patients: A randomized controlled trial study protocol

Appalasamy JR, Tha KK, Quek KF, Ramaiah SS, Joseph JP, Md Zain AZ

Medicine (Baltimore), 2018 Jun;97(22):e10876.
PMID: 29851804 DOI: 10.1097/MD.0000000000010876

INTRODUCTION: A substantial number of the world's population appears to end with moderate to severe long-term disability after stroke. Persistent uncontrolled stroke risk factor leads to unpredicted recurrent stroke event. The increasing prevalence of stroke across ages in Malaysia has led to the adaptation of medication therapy adherence clinic (MTAC) framework. The stroke care unit has limited patient education resources especially for patients with medication understanding and use self-efficacy. Nevertheless, only a handful of studies have probed into the effectiveness of video narrative at stroke care centers.
METHOD: This is a behavioral randomized controlled trial of patient education intervention with video narratives for patients with stroke lacking medication understanding and use self-efficacy. The study will recruit up to 200 eligible stroke patients at the neurology tertiary outpatient clinic, whereby they will be requested to return for follow-up approximately 3 months once for up to 12 months. Consenting patients will be randomized to either standard patient education care or intervention with video narratives. The researchers will ensure control of potential confounding factors, as well as unbiased treatment review with prescribed medications only obtained onsite.
RESULTS: The primary analysis outcomes will reflect the variances in medication understanding and use self-efficacy scores, as well as the associated factors, such as retention of knowledge, belief and perception changes, whereas stroke risk factor control, for example, self-monitoring and quality of life, will be the secondary outcomes.
DISCUSSION AND CONCLUSION: The study should be able to determine if video narrative can induce a positive behavioral change towards stroke risk factor control via enhanced medication understanding and use self-efficacy. This intervention is innovative as it combines health belief, motivation, and role model concept to trigger self-efficacy in maintaining healthy behaviors and better disease management.

Fulltext The immediate effect of facial candling on inflammatory mediators, substance P, symptoms severity, and quality of life in allergic rhinitis patients: Study protocol for a randomized controlled trial

Ismail NFF, Neoh CF, Lim SM, Abdullah AH, Mastuki MF, Ramasamy K, et al.

Medicine (Baltimore), 2017 Jul;96(30):e7511.
PMID: 28746195 DOI: 10.1097/MD.0000000000007511

INTRODUCTION: Asian countries have a variety of ethnic groups and culture that provide their own traditional treatment in health care. Facial candling appears to be one of the popular traditional treatments in Southeast Asian. The complementary medicine practitioners promote that the facial candling treatment would help in reducing the symptoms of allergic rhinitis and other problems related to sinus. Due to the lack of evidence available, the effectiveness of this treatment method and its mechanism, however, remains unknown. The objective of this research is therefore to study impact of facial candling on inflammatory mediators, substance P (SP), symptoms severity, and quality of life (QoL) in allergic rhinitis patients.
METHOD AND ANALYSIS: A randomized, nonblinded, controlled trial will be carried out by recruiting a total of 66 eligible allergic rhinitis patients who fulfill the inclusion criteria from a university health center. The subjects will be randomly assigned into 2 groups: intervention group receiving facial candling treatment and control group (no treatment given). Samples of blood and nasal mucus will be collected right before and after intervention. Samples collected will be analyzed. The primary outcomes are the changes in the level of SP in both blood and mucus samples between both groups. The secondary outcomes include the levels of inflammatory mediators (ie, tumor necrosis factor alpha, interleukin (IL)-3, IL-5, IL-6, IL-10, and IL-13) and the severity of allergic rhinitis symptoms as measured by a visual analogous scale and QoL using the Rhinitis Quality of Life Questionnaire (RQLQ).
ETHICAL AND TRIAL REGISTRATION: The study protocols are approved from the Ethical and Research Committee of the Universiti Teknologi MARA (REC/113/15). The trial is registered under the Australia New Zealand Clinical Trial Registry (ACTRN12616000299404). The trial was registered on 03/07/2016 and the first patient was enrolled on 10/12/2016.
CONCLUSION: Facial candling is one of the unique treatments using candles to reduce the severity of symptoms and inflammation. This is the first ever study conducted on facial candling that will give rise to new knowledge underlying the effects of facial candling on severity of symptoms and inflammation relief mechanism mediated by substance P and inflammatory mediators.

PMID: 37443466 DOI: 10.1097/MD.0000000000033966

BACKGROUND: Training caregivers and persons with Parkinson Disease (PwPD) is crucial to provide them with adequate knowledge and care skills in preparation for the Parkinson disease (PD) progression. This review will systematically evaluate the effect of structured training programs on the mobility and quality of life (QoL) of PwPD. In addition, the effect of such training programs on the QoL, burden of caregiving, and knowledge of PD among adult caregivers of PwPD will also be evaluated.
METHODS: Systematic and comprehensive search of relevant studies will be conducted using electronic databases such as Cochrane Library, EBSCOhost, PubMed, SCOPUS, and Web of Science. The title, abstract, keywords, and full texts will be screened for eligibility. Studies to be selected are randomized controlled trials (RCT) from inception until April 2023. Studies based on structured PD training either in the form of training, education, program, multidisciplinary approach, or self-management targeted at both PwPD and their adult caregivers will be selected. Only full-text articles available in the English language will be included. Full-text articles will be inspected by 2 independent reviewers to produce the final set of articles that meet the eligibility criteria. A third reviewer will be engaged if no consensus is achieved between the first and second reviewers. Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2) will be used to evaluate the quality of papers and inform the risk of bias.
RESULTS: This review will provide an outlook on the effects of structured PD training programs on mobility and QoL of PwPD. In addition, it will provide insight into the effects of such training on the caregivers' burden, knowledge of PD, and QoL.
CONCLUSION: This review findings may help clinicians and researchers to understand the effect of structured and comprehensive PD training programs for PwPD and their adult caregiver.

PMID: 37443502 DOI: 10.1097/MD.0000000000034249

BACKGROUND: Motor impairment is common after a stroke and directly affects the function and quality of life of stroke survivors. Constraint-induced movement therapy and neuromuscular electrical stimulation are interventions that facilitate functional recovery of the upper extremities of a particular subgroup of stroke survivors. The objective of this study was to summarize the available evidence on the effects of neuromuscular electrical stimulation combined with constraint-induced movement therapy in patients with stroke.
METHODS: We conducted a comprehensive search of published articles in electronic databases, including PubMed, Scopus, PEDro, Medline (via Ovid), EMBASE, Cochrane Library, and Web of Science, using the following search terms: "stroke"; "upper extremity"; "Constraint-Induced Movement Therapy"; and "Neuromuscular Electrical Stimulation." The search included published studies, conferences, and presentations. The article selection, data extraction, and quality evaluation will be conducted independently by 2 reviewers. The 3rd and 4th reviewers will assist in resolving any disagreements that may arise between the 2 reviewers. The risk of bias in the included studies will be assessed using the PEDro scale and Cochrane risk of bias assessment tool. Narrative synthesis and meta-analysis will be performed based on the characteristics of the included articles, including the risk of bias (if sufficient information is available).
RESULTS: This review summarizes the available evidence and could assist therapists in choosing the best treatment for poststroke upper extremity dysfunction.
CONCLUSION: This study will provide the available evidence on the effectiveness of CIMT and NMES on upper extremity function in patients with stroke.
ETHICS AND DISSEMINATION: Ethical approval is not required because the review will be based on publicly available literature. The findings of this study will be published in a peer-reviewed journal, and updates will be made depending on whether sufficient additional evidence modifies the conclusions of the review. Any changes made to the methods throughout the review will be stated in the article.

The primary target of severe acute respiratory syndrome coronavirus 2 is the respiratory system including the nose and lungs, however, it can also damage the kidneys, cardiovascular system and gastrointestinal system. Many recent reports suggested that severe acute respiratory syndrome coronavirus 2 infections can also affect the central nervous system as well as peripheral nervous system that lead to the several neurological complications. The virus can break the blood brain barrier and enters the brain via haematological route or directly by the angiotensin-converting enzyme 2 receptors present on endothelial cells of many cerebral tissues. The neurological complications are manifested by headache, dizziness, encephalopathy, encephalitis, cerebrovascular disease, anosmia, hypogeusia, muscle damage, etc. This review article described the possible routes and mechanism of nervous system infection and the range of neurological complications of COVID-19 that may help the medical practitioners and researchers to improve the clinical treatment and reduce the mortality rate among patients with viral diseases.

The outbreak of Coronavirus disease 2019 (Covid-19) has a significant impact on the mental health of the global population. Updates are needed regarding the mental health status among the local population since limited studies were done so far. This research compared the prevalence of anxiety and depression symptoms among HCWs and non-HCWs. We also evaluated the factors associated with anxiety and depression symptoms among these 2 groups. This was a cross-sectional study conducted between September to December 2022. Online questionnaire was distributed to HCWs from 2 tertiary government hospitals. Non-HCWs from various occupational fields were recruited randomly. Generalised Anxiety Disorder 7 (GAD-7) and Patient Health Questionnaire 9 (PHQ-9) were used to screen for anxiety and depression symptoms respectively. Data were analyzed using IBM SPSS version 28.0. 200 questionnaires were distributed to HCWs and non-HCWs respectively. The response rate was 74.5% from HCWs and 82.5% from non-HCWs (P = .07). A total of 236 individuals (105 HCWs and 131 non-HCWs) were included in the study. Majority were female, married, highly educated and worked more than 8 hours per day. There was no significant difference for the prevalence of anxiety (37.2% vs 44.3%, P = .34) and depression symptoms (37.3% vs 35.1%, P = .75) between HCWs and non-HCWs. Among HCWs, poor workplace support (P = .009) and low income (P = .04) were associated with anxiety symptoms. Younger age (P = .02), single status (P = .01) and poor workplace support (P = .006) were associated with depression symptoms. More non-HCWs with a higher educational level were having anxiety and depression symptoms. Single status (P = .03), working away from home (P = .02), poor family support (P = .03) and quarantine as Covid-19 close contact (P = .04) were also associated with depression symptoms among non-HCWs. There is no significant difference between HCWs and non-HCWs experiencing possible anxiety or depressive symptoms in this study. However, attention should be paid to address associated factors identified among each group to promote good mental health.
Fulltext Low intensity extracorporeal shockwave therapy for chronic pelvic pain syndrome patients with erectile dysfunction

Daneshwar D, Nordin A

Medicine (Baltimore), 2022 Jan 14;101(2):e28546.
PMID: 35029213 DOI: 10.1097/MD.0000000000028546

INTRODUCTION: In this study, the efficacy of low intensity shock wave therapy (LSWT) in improving symptoms of chronic pelvic pain syndrome (CPPS) and erectile dysfunction (ED) was investigated.
METHODS: Men diagnosed with CPPS and ED (n = 50) were prescribed with LSWT. The LSWT was administered in 10 sessions over the course of 5 weeks at 3,000 pulses with .25 mJ/mm2 energy flow and 5 Hz frequency. Outcome parameters were measured before and after LSWT.
RESULTS: Clinical symptoms related to CPPS and ED were measured using four validated questionnaires namely National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI), the International Index of Erectile Function (IIEF), the International Prostate Symptom Score (IPSS), and Sexual Health Inventory for Men (SHIM). The effect of LSWT on each of the three domains of NIH-CPSI, namely Pain, Symptoms, and Quality of Life (QoL) were also analyzed. Uroflowmetry was measured to assess LSWT effect on urine voiding. The mean baseline CPPS symptoms on NIH-CPSI domains of pain, symptoms and QoL were 9.92 ± 5.72 (mean ± SD), 5.14 ± 14.5, and 8.02 ± 3.17, respectively. LSWT resulted in significant reduction of CPPS symptoms on all NIH-CPSI domains (Pain = .9 ± 1.37; Symptoms = .74 ± 1.03; QoL = 1.16 ± 1.78). The baseline means of CPPS symptoms on IIEF, IPSS, and SHIM were 45.42 ± 16.24, 24.68 ± 9.28, and 14.28 ± 6.02, respectively. LSWT significant improved CPPS symptoms on IIEF (49.48 ± 28.30) and IPSS (9.04 ± 7.01) but not on SHIM (16.02 ± 9.85). No statistically significant differences were observed with all uroflowmetry parameters.
CONCLUSION: The current study demonstrated for the first time the safety and efficacy of LSWT administered in 10 sessions over 5 weeks in improving symptoms of CPPS and ED without causing any significant adverse effect to the patient.
Fulltext Specificity of estimating femoral anteversion using linea aspera version for total hip arthroplasty: A three-dimensional computed tomography study

Mohamed Thajudeen MZ, Mahmood Merican A, Hashim MS, Nordin A

Medicine (Baltimore), 2022 Nov 11;101(45):e31398.
PMID: 36397421 DOI: 10.1097/MD.0000000000031398

Femoral anteversion is an important parameter that can prevent complication following total hip arthroplasty (THA) caused by improper positioning of the implant. However, assessing femoral anteversion can be challenging in situation with significant defect of the femoral neck. In this study, linea aspera version was nominated as alternative parameter to femoral anteversion. So, the main objective of this study is to determine whether femoral anteversion correlates with linea aspera version. Cross-sectional study. Three-dimensional images of 100 femora were generated and their femoral anteversion and linea aspera version was measured. Correlation between the parameters was calculated. The mean linea aspera version was 7.27° ± 12.17° (mean ± standard deviation) while the mean femoral anteversion was 11.84° ± 10.06°. The linea aspera version was inversely correlated with the femoral anteversion with a correlation coefficient of -0.85. Linea aspera should be considered as an additional bony landmark to assess proper implant positioning in THA.

PMID: 33350786 DOI: 10.1097/MD.0000000000023897

BACKGROUND: Breast-cancer related lymphedema (BCRL) is a common condition among breast cancer survivors that could impact the quality of life (QoL) of patients. Exploring the QoL of the patients with BCRL using valid and reliable QoL is crucial to capture the status of this important aspect hence appropriate intervention could be implement to patient. However, so far no scientific review is available, which reports the psychometric properties of the QoL questionnaires used in BCRL. The purpose of this systematic review is to comprehensively assess the psychometric properties of QoL questionnaires in patients with BCRL.
METHODS: We will perform comprehensive searches of published studies in electronic databases such as Medline (via Ovid), EBSCOhost, PubMed, Scopus, and Web of Science by using the following search terms: "quality of life"; "breast cancer"; "upper limb"; "lymphedema"; "questionnaire"; and "measurement properties." Only full-text articles in English language are included. Two reviewers will independently conduct the article selection, data extraction, and quality assessment. Any possible conflict between the 2 reviewers is going to be solved with the help of a third reviewer. The Consensus-based Standards for the Selection of Health Measurement Instrument (COSMIN) checklist and manual will be used to assess the selected study quality.
RESULTS: This review will provide an updated overview of available lymphedema-specific questionnaires used in BCRL population and then recommend the most valid and reliable QoL questionnaire for clinical and research use in patients with BCRL.
CONCLUSION: This review may help the clinician and researcher to find an updated overview of various questionnaires used to assess BCRL patients' QoL.
ETHICS AND DISSEMINATION: This review will use data from published studies. Therefore, ethical approval is not required prior to this review. The results of this review will be published in a peer-reviewed journal or presented at conferences.

PMID: 34871247 DOI: 10.1097/MD.0000000000027675

ABSTRACT: The study aims to evaluate previous management of CRSwNP patients in Universiti Kebangsaan Malaysia Medical Center (UKMMC) against a developed CP.Chronic rhinosinusitis with nasal polyposis (CRSwNP) has high economic burden and impacts patient's quality of life. Implementation of clinical pathway (CP) can standardize care while optimizing resources.Analytical cross-sectionalThis study utilized medical records of 103 CRSwNP patients at UKMMC otorhinolaryngology clinic from 2010 to 2015. Patients were divided into groups who underwent or did not undergo surgery. Information was obtained regarding sociodemographic, follow-ups, pharmaceutical regimes, and treatment cost. Cost analysis was done using top-down analysis and activity-based costing and CP was formulated. Cost was calculated using year 2020 rates to adjust for inflation. (United States Dollars [USD]1 = Ringgit Malaysia [RM] 4.2015)Study showed non-CP patients were undertreated compared to CP. This affects clinical outcomes as optimal treatment demanded by CP was not achieved. Total cost for non-CP, non-surgery patients were lower (USD660) compared to CP (USD780) due to under treatment and shorter follow-ups. Meanwhile, total cost for non-CP surgery patients were higher (USD3600) compared to CP (USD2706) due to longer visit durations and hospital stays. Non-CP surgery group underwent lengthy follow-up duration (20.7 months) prior to operation compared to 12 months expected in CP.Study showed non-CP patients were undertreated compared to CP. We identified aspects which resulted in resource wastage and unnecessary burden to our healthcare system. This study enables development of a written CP by fine-tuning various aspects of CP which could be applied to our future practice.

Studies are divided on the effect of day-night temporal differences on clinical outcomes in out-of-hospital cardiac arrest (OHCA). This study aimed to elucidate any differences in OHCA survival between day and night occurrence, and the factors associated with differences in survival.This was a prospective, observational study of OHCA cases across multinational Pan-Asian sites. Cases were divided according to time call received by dispatch centers into day (0700H-1900H) and night (1900H-0659H). Primary outcome was 30-day survival. Secondary outcomes were prehospital and hospital modifiable resuscitative characteristics.About 22,501 out of 55,881 cases occurred at night. Night cases were less likely to be witnessed (40.2% vs. 43.1%, P
Fulltext Circadian rhythm in systemic autoimmune conditions: Potential of chrono-immunology in clinical practice: A narrative review

Awuah WA, Huang H, Kalmanovich J, Mehta A, Mikhailova T, Ng JC, et al.

Medicine (Baltimore), 2023 Aug 11;102(32):e34614.
PMID: 37565922 DOI: 10.1097/MD.0000000000034614

The circadian rhythm (CR) is a fundamental biological process regulated by the Earth's rotation and solar cycles. It plays a critical role in various bodily functions, and its dysregulation can have systemic effects. These effects impact metabolism, redox homeostasis, cell cycle regulation, gut microbiota, cognition, and immune response. Immune mediators, cycle proteins, and hormones exhibit circadian oscillations, supporting optimal immune function and defence against pathogens. Sleep deprivation and disruptions challenge the regulatory mechanisms, making immune responses vulnerable. Altered CR pathways have been implicated in diseases such as diabetes, neurological conditions, and systemic autoimmune diseases (SADs). SADs involve abnormal immune responses to self-antigens, with genetic and environmental factors disrupting self-tolerance and contributing to conditions like Systemic Lupus Erythematosus, Rheumatoid Arthritis, and Inflammatory Myositis. Dysregulated CR may lead to increased production of pro-inflammatory cytokines, contributing to the systemic responses observed in SADs. Sleep disturbances significantly impact the quality of life of patients with SADs; however, they are often overlooked. The relationship between sleep and autoimmune conditions, whether causal or consequential to CR dysregulation, remains unclear. Chrono-immunology investigates the role of CR in immunity, offering potential for targeted therapies in autoimmune conditions. This paper provides an overview of the connections between sleep and autoimmune conditions, highlighting the importance of recognizing sleep disturbances in SADs and the need for further research into the complex relationship between the CR and autoimmune diseases.

Over half of metabolic syndrome (MetS) patients have nonalcoholic fatty liver disease (NAFLD). To prevent its complications, standard routine screening is required, but the human-resource and budgetary implications need to be taken into consideration. This study compared the performances of 4 noninvasive scoring systems in predicting NAFLD in MetS patients. They were the fatty liver index, hepatic steatosis index, lipid accumulation product index, and nonalcoholic fatty liver disease in metabolic syndrome patients scoring system (NAFLD-MS).Scores were determined for 499 MetS patients, including 249 patients in a type 2 diabetes mellitus (T2DM) subgroup. Ultrasonography was used to diagnose NAFLD. The accuracies and performance of the scoring systems were analyzed using published cutoff values, and comparisons were made of their areas under receiver operating characteristic curves, sensitivities, specificities, positive and negative predictive values, and likelihood ratios.NAFLD was detected in 68% of the MetS patients and 77% of the MetS patients with T2DM. According to the areas under receiver operating characteristic curves, fatty liver index and hepatic steatosis index provided better performances in predicting NAFLD. NAFLD-MS provided the highest specificity of 99% among the MetS patients as a whole, and it provided even better accuracy with similar performance when applied to the subgroup of MetS patients with T2DM. The maximum cost avoidance from unnecessary ultrasonography was also reported by using NAFLD-MS. In terms of simplicity and ease of calculation, the lipid accumulation product index and NAFLD-MS are preferred.All 4 scoring systems proved to be acceptable for predicting NAFLD among MetS and T2DM patients in settings where the availability of ultrasonography is limited. NAFLD-MS provided the highest specificity and cost avoidance, and it is simple to use. All 4 systems can help clinicians decide further investigations.

BACKGROUND: Controversy remains concerning the association of the all-cause mortality risk of hospitalized cardiovascular disease (CVD) patients with non-alcoholic fatty liver disease (NAFLD). This study investigated the risks of all-cause mortality among hospitalized CVD patients with NAFLD.
METHODS: We used related keywords to search for studies in 3 electronic databases: PubMed, EMBASE, and Cochrane Library. All eligible studies published up to April 2020 were reviewed. The findings of those studies reporting the mortality outcomes of hospitalized CVD patients with and without NAFLD were examined, and the various study results were pooled and analyzed using a random-effects model. A quality assessment using the Newcastle-Ottawa scale was performed on the studies selected for inclusion in a meta-analysis.
RESULTS: A total of 2135 studies were found, of which 3 were included in this meta-analysis. All studies were considered good quality. The mean age of the patients in the analysis was 73 years, and about half of them were men. The comorbidities reported were hypertension, diabetes mellitus, and dyslipidemia. The results showed that hospitalized CVD patients with NAFLD were at a significantly higher risk of all-cause mortality than non-NAFLD patients (adjusted hazard ratio of 2.08 [95% confidence interval, 1.56-2.59], P

Necrotizing fasciitis (NF) is a life-threatening soft tissue infection that rapidly progresses and requires urgent surgery and medical therapy. If treatment is delayed, the likelihood of an unfavorable outcome, including death, is significantly increased. The goal of this study was to develop and validate a novel scoring model for predicting mortality in patients with NF. The proposed system is hereafter referred to as the Mortality in Necrotizing Fasciitis (MNF) scoring system. A total of 1503 patients with NF were recruited from 3 provincial hospitals in Thailand during January 2009 to December 2012. Patients were randomly allocated into either the derivation cohort (n = 1192) or the validation cohort (n = 311). Clinical risk factors used to develop the MNF scoring system were determined by logistic regression. Regression coefficients were transformed into item scores, the sum of which reflected the total MNF score. The following 6 clinical predictors were included: female gender; age > 60 years; white blood cell (WBC) ≤5000/mm3; WBC ≥ 35,000/mm3; creatinine ≥ 1.6 mg/dL, and pulse rate > 130/min. Area under the receiver operating characteristic curve (AuROC) analysis showed the MNF scoring system to have moderate power for predicting mortality in patients with NF (AuROC: 76.18%) with good calibration (Hosmer-Lemeshow χ2: 1.01; P = .798). The positive likelihood ratios of mortality in patients with low-risk scores (≤2.5) and high-risk scores (≥7) were 11.30 (95% confidence interval [CI]: 6.16-20.71) and 14.71 (95%CI: 7.39-29.28), sequentially. When used to the validation cohort, the MNF scoring system presented good performance with an AuROC of 74.25%. The proposed MNF scoring system, which includes 6 commonly available and easy-to-use parameters, was shown to be an effective tool for predicting mortality in patients with NF. This validated instrument will help clinicians identify at-risk patients so that early investigations and interventions can be performed that will reduce the mortality rate among patients with NF.
