Effectiveness of intensive perioperative nutrition therapy among adults undergoing gastrointestinal and oncological surgery in a public hospital: study protocol for a pragmatic randomized control trial

A'zim AZA, Zaid ZA, Yusof BNM, Jabar MF, Shahar ASM

Trials, 2022 Nov 26;23(1):961.
PMID: 36435838 DOI: 10.1186/s13063-022-06898-2

BACKGROUND: Perioperative malnutrition is common in patients undergoing gastrointestinal-oncology surgery and is associated with longer hospital stays, increased postoperative complications, poorer quality of life, and lower survival rates. Current practice emphasizes the role of early perioperative nutrition therapy as an early intervention to combat the postoperative complications of patients and the implementation is now widely adopted. However, there is still a lack of research on determining the effectiveness of intensive nutrition therapy and providing ONS perioperative locally. This becomes the significance of this study and serves as a basis for management and guideline in the local hospital settings.
METHODS: This is a pragmatic randomized control trial study where elective admitted patients will be randomly divided into the intervention (SS) or control (NN) group. All data will be collected during a face-to-face interview, anthropometric measurement, blood sampling (albumin, white blood count, hemoglobin, and c-reactive protein), handgrip strength, and postoperative complications. Group SS will be receiving a tailored lifestyle and intensively supplemented with oral nutrition support as compared to Group NN that will receive standard medical care. The primary outcome for this study is the length of stay in the hospital. Additional outcome measures are changes in biochemical profile and nutritional and functional status. The effects of intervention between groups on the outcome parameters will be analyzed by using the SPSS General Linear Model (GLM) for the repeated measure procedure.
DISCUSSION: The intervention implemented in this study will serve as baseline data in providing appropriate nutritional management in patients undergoing gastrointestinal and oncological surgery.

Fulltext Current practices in cancer pain management in Asia: a survey of patients and physicians across 10 countries

ACHEON Working Group, Kim YC, Ahn JS, Calimag MM, Chao TC, Ho KY, et al.

Cancer Med, 2015 Aug;4(8):1196-204.
PMID: 25914253 DOI: 10.1002/cam4.471

In order to implement more effective policies for cancer pain management, a better understanding of current practices is needed. Physicians managing cancer pain and patients experiencing cancer pain were randomly surveyed across 10 Asian countries to assess attitudes and perceptions toward cancer pain management. A total of 463 physicians (77.3% oncologists) with a median experience of 13 years were included. Medical school training on opioid use was considered inadequate by 30.5% of physicians and 55.9% indicated ≤ 10 h of continuing medical education (CME). Of the 1190 patients included, 1026 reported moderate-to-severe pain (median duration, 12 months). Discordance was observed between physician and patient outcomes on pain assessment with 88.3% of physicians reporting pain quantification, while 49.5% of patients claimed that no scale was used. Inadequate assessment of pain was recognized as a barrier to therapy optimization by 49.7% of physicians. Additional barriers identified were patients' reluctance owing to fear of addiction (67.2%) and adverse events (65.0%), patients' reluctance to report pain (52.5%), excessive regulations (48.0%) and reluctance to prescribe opioids (42.8%). Opioid use was confirmed only in 53.2% (286/538) of patients remembering their medication. Pain affected the activities of daily living for 81.3% of patients. These findings highlight the need for better training and CME opportunities for cancer pain management in Asia. Collaborative efforts between physicians, patients, policy makers, and related parties may assist in overcoming the barriers identified. Addressing the opioid stigma and enhancing awareness is vital to improving current standards of patient care.

Aazami S, Mozafari M, Shamsuddin K, Akmal S

Ind Health, 2016;54(1):50-7.
PMID: 26423332 DOI: 10.2486/indhealth.2015-0086

This study aimed at assessing effect of the four dimensions of work-family conflicts (strain and time-based work interference into family and family interference into work) on sleep disturbance in Malaysian working women. This cross-sectional study was conducted among 325 Malaysian married working women. Multiple-stage simple random sampling method was used to recruit women from public service departments of Malaysia. Self-administrated questionnaires were used to measure the study variables and data were analyzed using SPSS version 21. We found that high level of the four dimensions of work-family conflicts significantly increase sleep disturbance. Our analyses also revealed an age-dependent effect of the work-family conflict on sleep disturbance. Women in their 20 to 30 yr old suffer from sleep disturbance due to high level of time-based and strain-based work-interference into family. However, the quality of sleep among women aged 30-39 were affected by strain-based family-interference into work. Finally, women older than 40 yr had significantly disturbed sleep due to strain-based work-interference into family as well as time-based family interference into work. Our findings showed that sleep quality of working women might be disturbed by experiencing high level of work-family conflict. However, the effects of inter-role conflicts on sleep varied among different age groups.

Fulltext General and erosive tooth wear of 16-year-old adolescents in Kuantan, Malaysia: prevalence and association with dental caries

Ab Halim N, Esa R, Chew HP

BMC Oral Health, 2018 01 12;18(1):11.
PMID: 29329566 DOI: 10.1186/s12903-017-0451-9

BACKGROUND: The objective of this study was to determine the prevalence and severity of general tooth wear (GTW), i.e. tooth wear irrespective of etiology and erosive tooth wear (ETW), i.e. tooth wear predominantly due to erosion; and also to investigate the relationship between ETW and dental caries experience in 16-year-old adolescents in Kuantan, Malaysia.
METHODS: A multi-staged cluster sampling method was employed. A total of 598 16-year-old adolescents participated in this study. Participants' demographic profile was assessed through a self-administered questionnaire. Clinical examinations were carried out under standardized conditions by a single examiner. The level of GTW was recorded using the modified Smith and Knight's Tooth Wear Index (TWI) whilst ETW were recorded using the Basic Erosive Wear Examination (BEWE) index. This index was developed to record clinical findings and assist in the decision-making process for the management of erosive tooth wear. Dental caries was recorded using the D3MFT index whereby D3 denotes obvious dental decay into dentine detected visually.
RESULTS: The prevalence of GTW, ETW and dental caries, i.e. percentage of individuals found to have at least one lesion, was 99.8%, 45.0% and 27.8% respectively. Two thirds of affected teeth with GTW were observed to have a TWI score of 1 whereas almost all of the affected teeth with ETW had a BEWE score of 2. The mean D3MFT was 0.62 (95% CI 0.50, 0.73) with Decayed (D) teeth being the largest component, mean D3T was 0.36 (95% CI 0.30, 0.43). There was no significant association between socio-demographic factors and prevalence of ETW. Logistic regression analysis also showed no significant relationship between the prevalence of ETW and D3MFT (p > 0.05).
CONCLUSIONS: Almost all adolescents examined had GTW but they were mainly early lesions. However, nearly half were found to have ETW of moderate severity (BEWE score 2). No significant relationship between the occurrence of erosive tooth wear and caries was observed in this population.

Ab Rahman SS, Nik Mazian A, Samad SZ

Trop Med Int Health, 2023 Nov;28(11):864-868.
PMID: 37778744 DOI: 10.1111/tmi.13936

Dengue is endemic in over 100 countries worldwide, predominantly in the subtropical and tropical regions and the incidence has been increasing globally. Patients with severe dengue may develop massive bleeding, disseminated intravascular coagulopathy and multi-organ failure. Bleeding may occur in various body cavities and muscles; however, bleeding in the retroperitoneal space is uncommon. We report a case of a 37-year-old gentleman who presented with a 4-day history of fever associated with chills and rigours. On Day 6 of illness, he complained of left lumbar and left iliac fossa pain which was aggravated by movement. A computed tomography angiography scan of the abdomen showed the presence of a retroperitoneal haematoma, left iliopsoas and quadratus lumbarum intramuscular haematoma with active bleeding and left abdominal wall muscles haematoma. His condition gradually improved after multiple blood transfusions and he gained full recovery. Spontaneous retroperitoneal haematoma is an uncommon complication of severe dengue infection. Early diagnosis based on high index of clinical suspicion using appropriate imaging will aid in prompt management of these cases and may prevent deaths.

Frequency and characteristics of acne-related post-inflammatory hyperpigmentation

Abad-Casintahan F, Chow SK, Goh CL, Kubba R, Hayashi N, Noppakun N, et al.

J Dermatol, 2016 Jul;43(7):826-8.
PMID: 26813513 DOI: 10.1111/1346-8138.13263

In patients with darker skin types (Fitzpatrick phototypes III-VI), acne is often accompanied by post-inflammatory hyperpigmentation (PIH). Further, acne-related pigmentation can pose a greater concern for the patient than the acne lesions. There has been little formal study of this acne-related PIH. Recently, the Asian Acne Board - an international group of dermatologists with interest in acne research - made a preliminary evaluation of the frequency and characteristics of PIH in seven Asian countries. A total of 324 sequential acne subjects were evaluated for the presence of PIH. The majority (80.2%) of subjects had mild to moderate acne and there were more females than males (63.0% vs 37.0%). In this population of patients consulting a dermatologist for acne, 58.2% (188/324) had PIH. The results also showed that pigmentation problems are often long lasting: at least 1 year for more than half of subjects and 5 years or longer in 22.3%. In accordance with our clinical experience, patients reported that PIH is quite bothersome, often as bothersome or more so than the acne itself and sometimes more problematic. Excoriation was commonly reported by patients, and may represent a modifiable risk factor that could potentially be improved by patient education.

Fulltext Non-fatal occupational injuries among non-governmental employees in Malaysia

Abas AB, Said AR, Mohammed MA, Sathiakumar N

Int J Occup Environ Health, 2011 Jan-Mar;17(1):38-48.
PMID: 21344818

We analyzed data on non-fatal occupational injuries reported to Malaysia's social security organization from 2002 to 2006. There was a decrease in both the absolute number and the incidence rates of these injuries over time. About 40% of cases occurred in the manufacturing sector followed by the service (17%) and trading (17%) sectors. The agriculture sector reported the highest incidence rate (24.1/1,000), followed by the manufacturing sector subcategories of wood-product manufacturing (22.1/1,000) and non-metallic industries (20.8/1,000). Men age 40 to 59 and persons of Indian ethnicity had a greater tendency to sustain injuries. Government and non-governmental organizations should strive to develop strategies to reduce the occupational injuries targeting vulnerable groups. Enforcement of safety measures will further play an important role to ensure that both employees and employers take special precautions to address workplace hazards.

Oversized acetabular socket causing groin pain after total hip arthroplasty

Abbas AA, Kim YJ, Song EK, Yoon TR

J Arthroplasty, 2009 Oct;24(7):1144.e5-8.
PMID: 18848418 DOI: 10.1016/j.arth.2008.09.008

The causes of groin pain after total hip arthroplasty are numerous, and the condition itself is disabling. Therefore, it is imperative that the cause of the pain is identified and managed appropriately. We report a case where the patient had groin pain after total hip arthroplasty as a result of an oversized cementless acetabular component, which caused a breach in the anterior wall of the acetabulum. The anterior wall of the acetabulum was reconstructed with femoral head allograft, and the patient has been symptom free since.

Numerical investigation on the effect of bileaflet mechanical heart valve's implantation tilting angle and aortic root geometry on intermittent regurgitation and platelet activation

Abbas SS, Nasif MS, Al-Waked R, Meor Said MA

Artif Organs, 2020 Feb;44(2):E20-E39.
PMID: 31378963 DOI: 10.1111/aor.13536

Platelet activation induced by shear stresses and non-physiological flow field generated by bileaflet mechanical heart valves (BMHVs) leads to thromboembolism, which can cause fatal consequences. One of the causes of platelet activation could be intermittent regurgitation, which arises due to asynchronous movement and rebound of BMHV leaflets during the valve closing phase. In this numerical study, the effect of intermittent regurgitation on the platelet activation potential of BMHVs was quantified by modeling a BMHV in the straight and anatomic aorta at implantation tilt angles 0°, 5°, 10°, and 20°. A fully implicit Arbitrary Lagrangian-Eulerian-based Fluid-Structure Interaction formulation was adopted with blood modeled as a multiphase, non-Newtonian fluid. Results showed that the intermittent regurgitation and consequently the platelet activation level increases with the increasing implantation tilt of BMHV. For the straight aorta, the leaflet of the 20° tilted BMHV underwent a rebound of approximately 20° after initially closing, whereas the leaflet of the 10°, 5°, and 0° tilted BMHVs underwent a rebound of 8.5°, 3°, and 0°, respectively. For the anatomic aorta, the leaflet of the 20° tilted BMHV underwent a rebound of approximately 24° after initially closing, whereas the leaflet of the 10°, 5°, and 0° tilted BMHVs underwent a rebound of 14°, 10°, and 7°, respectively. For all the implantation orientations of BMHVs, intermittent regurgitation and platelet activation were always higher in the anatomic aorta than in the straight aorta. The study concludes that the pivot axis of BMHV must be implanted parallel to the aortic root's curvature to minimize intermittent regurgitation and platelet activation.

Fulltext Risk factors associated with nosocomial infections among end stage renal disease patients undergoing hemodialysis: A systematic review

Abbasi SH, Aftab RA, Chua SS

PLoS One, 2020;15(6):e0234376.
PMID: 32569265 DOI: 10.1371/journal.pone.0234376

BACKGROUND: Profound healthcare challenges confront societies with an increase in prevalence of end-stage renal disease (ESRD), which is one of the leading causes of morbidity and mortality worldwide. Due to several facility and patient related factors, ESRD is significantly associated with increased morbidity and mortality attributed to infections.
AIMS AND OBJECTIVE: The aim of this study was to assess systematically the characteristics of patients and risk factors associated with nosocomial infections among ESRD patients undergoing hemodialysis.
METHODS: A systematic literature search was performed to identify eligible studies published during the period from inception to December 2018 pertaining to risk factors associated with nosocomial infections among hemodialysis patients. The relevant studies were generated through a computerized search on five databases (PubMed, EBSCOhost, Google Scholar, ScienceDirect and Scopus) using the Mesh Words: nosocomial infections, hospital acquired infections, healthcare associated infections, end stage renal disease, end stage renal failure, hemodialysis, and risk factors. The complete protocol has been registered under PROSPERO (CRD42019124099).
RESULTS: Initially, 1411 articles were retrieved. Out of these, 24 were duplicates and hence were removed. Out of 1387 remaining articles, 1337 were removed based on irrelevant titles and/or abstracts. Subsequently, the full texts of 50 articles were reviewed and 41 studies were excluded at this stage due to lack of relevant information. Finally, nine articles were selected for this review. Longer hospital stay, longer duration on hemodialysis, multiple catheter sites, longer catheterization, age group, lower white blood cell count, history of blood transfusion, and diabetes were identified as the major risk factors for nosocomial infections among hemodialysis patients.
CONCLUSION: The results of this review indicate an information gap and potential benefits of additional preventive measures to further reduce the risk of infections in hemodialysis population. Moreover, several patient-related and facility-related risk factors were consistently observed in the studies included in this review, which require optimal control measures.

Efficacy and safety of dexmedetomidine versus morphine in post-operative cardiac surgery patients

Abd Aziz N, Chue MC, Yong CY, Hassan Y, Awaisu A, Hassan J, et al.

Int J Clin Pharm, 2011 Apr;33(2):150-4.
PMID: 21744187 DOI: 10.1007/s11096-011-9480-7

OBJECTIVE: To compare the efficacy of dexmedetomidine versus morphine as a sedative/analgesic among post-operative cardiac surgery patients.
METHOD: A randomized controlled open-label study was performed at the cardiothoracic intensive care unit of Penang Hospital, Malaysia. A total of 28 patients who underwent cardiac surgeries were randomly assigned to receive either dexmedetomidine or morphine. Both groups were similar in terms of preoperative baseline characteristics. Efficacy measures included sedation scores and pain intensity and requirements for additional sedative/analgesic. Mean heart rate and arterial blood pressure were used as safety measures. Other measures were additional inotropes, extubation time and other concurrent medications.
RESULTS: The mean dose of dexmedetomidine infused was 0.12 [SD 0.03] μg kg⁻¹ h⁻¹, while that of morphine was 13.2 [SD 5.84] μg kg⁻¹ h⁻¹. Dexmedetomidine group showed more benefits in sedation and pain levels, additional sedative/analgesic requirements, and extubation time. No significant differences between the two groups for the outcome measures, except heart rate, which was significantly lower in the dexmedetomidine group.
CONCLUSION: This preliminary study suggests that dexmedetomidine was at least comparable to morphine in terms of efficacy and safety among cardiac surgery patients. Further studies with larger samples are recommended in order to determine the significant effects of the outcome measures.

Long-Term Health Outcome and Quality of Life Post-HSCT for IL7Rα-, Artemis-, RAG1- and RAG2-Deficient Severe Combined Immunodeficiency: a Single Center Report

Abd Hamid IJ, Slatter MA, McKendrick F, Pearce MS, Gennery AR

J Clin Immunol, 2018 08;38(6):727-732.
PMID: 30105620 DOI: 10.1007/s10875-018-0540-9

Hematopoietic stem cell transplantation (HSCT) is curative for severe combined immunodeficiency (SCID), but data on long-term impact of pre-HSCT chemotherapy, immune reconstitution and quality of life (QoL) of specific SCID genotypes are limited. We evaluated the long-term immune-reconstitution, health outcome and QoL in IL7Rα SCID, Artemis and RAG1 and 2 SCID survivors > 2 years post-HSCT in our center. Clinical data and immune reconstitution parameters were collated, and patients/families answered PedsQL generic core scale v4.0 questionnaires. Thirty-nine patients with a diagnosis of IL7Rα SCID (17 patients), Artemis SCID (8 patients) and RAG1/2 SCID (13 patients) had undergone HSCT with median age at last follow up for IL7Rα SCID, 14 years (range 4-27) and Artemis and RAG1/2 SCID, 10 years (range 2-18). Many patients have ongoing medical issues at latest follow-up [IL7Rα (73%), Artemis (85%), RAG1/2 (55%)]. Artemis SCID patients experienced more sequela than RAG1/2 SCID. Conditioned recipients with Artemis and RAG SCID had more CD4+ naïve lymphocytes compared to unconditioned recipients. All patients except those of IL7Rα SCID reported lower QoL; further subset group analysis showed parents and Artemis and RAG1/2 survivors without ongoing medical issues reported normal QoL. Conditioned recipients have superior long-term thymopoiesis, chimerism and immunoglobulin-independence. QoL was normal in those who did not have medical issues at long-term follow-up.

Abd Hamid MF, Abdul Razak S, Azraai AM, Miptah HN

Am J Case Rep, 2023 Nov 10;24:e941089.
PMID: 37946402 DOI: 10.12659/AJCR.941089

BACKGROUND The article discusses an unusual case of papillary thyroid carcinoma in which chronic cough and hemoptysis were the predominant symptoms. While the more common causes of hemoptysis are pulmonary in origin, extrapulmonary etiologies have been reported, including thyroid carcinoma. The clinical presentation of thyroid malignancy in this case mimics many other common disorders, such as pulmonary tuberculosis, bronchogenic carcinoma, bronchiectasis, and chronic obstructive pulmonary disease. Hence, making it challenging to suspect early when patients present to primary care. CASE REPORT A 54-year-old woman presented with a chronic cough and hemoptysis in our Primary Care Medicine Clinic. While initial assessments in the primary care medicine clinic yielded no remarkable findings, a subsequent high-resolution computed tomography scan of the thorax uncovered a thyroid lesion. Subsequent evaluation in the hospital setting included an ultrasound examination, revealing multiple thyroid nodules, and fine needle aspiration that confirmed papillary thyroid carcinoma. She underwent total thyroidectomy with central and left lateral neck dissection, complicated by left vocal cord palsy. She received 2 cycles of periodic radioactive iodine therapy and injection laryngoplasty postoperatively. There was no evidence of iodin avid disease and recurrence of hemoptysis after surgery. CONCLUSIONS This case report emphasizes the significance of considering papillary thyroid carcinoma when assessing hemoptysis in the primary care setting, as early detection and treatment of it would result in a better outcome.

Abd Rahman MN, Abdul Rani MR, Rohani JM

J Hum Ergol (Tokyo), 2011 Dec;40(1-2):19-36.
PMID: 25665205 DOI: 10.11183/jhe.40.19

This paper describes the development of the Workplace Ergonomic Risk Assessment (WERA) for investigating the physical risk factor associated with work-related musculoskeletal disorders (WMSDs). The initial development of WERA tool involved the following procedures: (1) first stage, development of WERA prototype from literature review, (2) second stage, evaluation of the psychometric properties including (a) validity trials and (b) reliability and usability trials. In the validity trials, the relationship of the individual WERA body part scores to the development of pain or discomfort is statistically significant for the wrist, shoulder and back regions. It shows that the WERA assessment provided a good indication of work-related musculoskeletal disorders which might be reported as pain, ache or discomfort in the relevant body regions. In the reliability trials, the results of inter-observer reliability shows that moderate agreement among the observers while from the feedback questionnaire survey about the usability of WERA tool, all participants including expert and management teams agreed that the prototype of WERA tool was easy and quick to use, applicable to workplace assessment for the wide range of job/task and valuable at work. It was confirmed that there was no need of training required to do WERA assessment. Therefore, the WERA assessment has been designed for easy and quick use, and for those who are trained to use it do not need previous skills in observation techniques although this would be an advantage. As WERA is a pen and paper technique that can be used without any special equipment, WERA assessment can be done in any space of workplaces without disruption to the task that have been observed.

Cisplatin is a potent platinum-based anticancer drug approved by the Food Drug Administration (FDA) in 1978. Despite its advantages against solid tumors, cisplatin confers toxicity to various tissues that limit its clinical uses. In cisplatin-induced hepatotoxicity, few mechanisms have been identified, which started as excess generation of reactive oxygen species that leads to oxidative stress, inflammation, DNA damage and apoptosis in the liver. Various natural products, plant extracts and oil rich in flavonoids, terpenoids, polyphenols, and phenolic acids were able to minimize oxidative stress by restoring the level of antioxidant enzymes and acting as an anti-inflammatory agent. Likewise, treatment with honey and royal jelly was demonstrated to decrease serum transaminases and scavenge free radicals in the liver after cisplatin administration. Medicinal properties of these natural products have a promising potential as a complementary therapy to counteract cisplatin-induced hepatotoxicity. This review concentrated on the protective role of several natural products, which has been proven in the laboratory findings to combat cisplatin-induced hepatotoxicity.

The role of mTOR signalling pathway in hypoxia-induced cognitive impairment

Abdo Qaid EY, Zulkipli NN, Zakaria R, Ahmad AH, Othman Z, Muthuraju S, et al.

Int J Neurosci, 2021 May;131(5):482-488.
PMID: 32202188 DOI: 10.1080/00207454.2020.1746308

Hypoxia has been associated with cognitive impairment. Many studies have investigated the role of mTOR signalling pathway in cognitive functions but its role in hypoxia-induced cognitive impairment remains controversial. This review aimed to elucidate the role of mTOR in the mechanisms of cognitive impairment that may pave the way towards the mechanistic understanding and therapeutic intervention of hypoxia-induced cognitive impairment. mTORC1 is normally regulated during mild or acute hypoxic exposure giving rise to neuroprotection, whereas it is overactivated during severe or chronic hypoxia giving rise to neuronal cells death. Thus, it is worth exploring the possibility of maintaining normal mTORC1 activity and thereby preventing cognitive impairment during severe or chronic hypoxia.

Fulltext Total pleurectomy as the surgical treatment for recurrent secondary spontaneous pneumothorax in a child with severe pulmonary Langerhans cells histiocytosis

Abdul Aziz DA, Abdul Rahman NA, Tang SF, Abdul Latif H, Zaki FM, Annuar ZM, et al.

BMJ Case Rep, 2011;2011.
PMID: 22674944 DOI: 10.1136/bcr.09.2011.4734

Pulmonary Langerhans cell histiocytosis (LCH) in children is more extensive and is a rare cause of spontaneous secondary pneumothorax (SSP) which tends to be recurrent and refractory to conventional treatment. Its occurrence in paediatric patients posed great challenge to the choice of surgical management. Surgery in the form of pleurodesis is only considered if SSP does not improve after chemotherapy and after considering all relevant risk and benefits of surgery to patients. Chemical pleurodesis will not give the expected effect to eradicate SSP in this patient. Therefore mechanical pleurodesis is the treatment of choice. There are various techniques to perform mechanical pleurodesis; from pleural abrasion to pleurectomy. In the authors' experience, bilateral total pleurectomy provided the best outcome for this 9-year-old patient with persistent respiratory distress from SSP due to extensive pulmonary LCH.
