METHODS: This clinical trial was conducted at the Faculty of Dentistry, Universiti Teknologi MARA Shah Alam, Selangor, Malaysia, from September 2010 to April 2012. Periodontal chips were formulated using S. persica, benzyl isothiocyanate (BITC) and chitosan extracts. All patients were treated with full mouth scaling and root planing at baseline. Thereafter, the periodontal pockets (≥5 mm in length) were divided into 4 groups: the control group; group 2 (plain chitosan chip); group 3 (S. persica extract); and group 4 (BITC extract). Plaque index (PI), bleeding on probing (BOP), periodontal probing pocket depth and clinical attachment levels were recorded at days 0 and 60 only.
RESULTS: A total of 12 patients participated in this study. Overall, 240 periodontal pockets were evaluated. The study revealed significant improvements in PI, BOP and reduction in periodontal pocket depth in all 4 groups (P <0.05). The improvement in clinical attachment level was significantly higher (P <0.001) among the group that received S. persica chips compared to the control and other chip-treated groups.
CONCLUSION: Periodontal chips containing S. persica can be used as adjuncts to treat patients with periodontitis.
METHODS: This retrospective cohort study included 962 patients admitted to two hospitals in Kuwait with a confirmed diagnosis of COVID-19. Cumulative all-cause mortality rate was the primary outcome.
RESULTS: A total of 302 patients (males, 196 [64.9%]; mean age, 57.2 ± 14.6 years; mean body mass index, 29.8 ± 6.5 kg/m2) received anticoagulation therapy. Patients receiving anticoagulation treatment tended to have pneumonia (n = 275 [91.1%]) or acute respiratory distress syndrome (n = 106 [35.1%]), and high D-dimer levels (median [interquartile range]: 608 [523;707] ng/mL). The mortality rate in this group was high (n = 63 [20.9%]). Multivariable logistic regression, the Cox proportional hazards, and Kaplan-Meier models revealed that the use of therapeutic anticoagulation agents affected the risk of all-cause cumulative mortality.
CONCLUSION: Age, hypertension, pneumonia, therapeutic anticoagulation, and methylprednisolone use were found to be strong predictors of in-hospital mortality. In elderly hypertensive COVID-19 patients on therapeutic anticoagulation were found to have 2.3 times higher risk of in-hospital mortality. All cause in-hospital mortality rate in the therapeutic anticoagulation group was up to 21%.
METHODS: Between 2019 and 2022, 9 patients with NCs of the subaxial spine underwent an anterior microsurgical approach. Their clinical presentations, radiological features, operative findings, and follow-up data were retrospectively reviewed and analyzed.
RESULTS: All spinal cysts were intradural and extramedullary in origin. Five patients were first-time cases while 4 patients with recurrence underwent revision surgery. The most common clinical manifestation was pain (77.78%). One patient was found to have a concomitant disorder of Klippel-Feil syndrome. Microscopically confirmed gross-total resection was achieved in 8 patients (88.89%) based on clinical comparisons between pre- and postoperative MRI and intraoperative video. One patient had symptom recurrence 1 year after subtotal resection, while there was no evidence of recurrence during follow-up for the other patients. Dense adhesions within the spinal cord were observed in 8 patients (88.89%) intraoperatively. Most importantly, the surgical outcome was significantly improved in all patients, and the mean (± SE) Japanese Orthopaedic Association score increased from 11.33 ± 0.91 preoperatively to 16.22 ± 0.32 postoperatively (p = 0.008).
CONCLUSIONS: An anterior surgical approach was proven to be both safe and effective in treating the ventral or ventrolateral SCNCs. The authors believe that an anterior microsurgical approach should be considered as a useful approach especially in patients with ventral recurrent SCNCs. Its clinical efficacy compared with a posterior approach in ventral spinal cyst may be better as most of the neurenteric cysts are ventrally or ventrolaterally located.
METHODS: Primary data gathered with the help of questionnaires from employees of SMEs manufacturing in developing countries, Pakistan. The research gathered data from 211 participants by applying a pre-tested instrumental questionnaire and structural equation modelling (SEM) for data analysis.
RESULTS: The results confirmed all direct effects, including a reduction in resource use, the greening of processes and products and green employee behaviour of environmental strategies in small and medium manufacturing firms. Also, confirmed partial mediation effect of green employee behavior between greening of processes and products and environmental strategy.
CONCLUSION: The current study clearly showed the need for programs and infrastructures that support resource reduction and greening businesses in SMEs. Companies' implementation of green processes and technologies allows SMEs to take an environmentally responsible stand and become part of the movement toward sustainability. The research stresses the importance of green employee conduct as a mediator, the central point being the individual employee being engaged and aware of the subject and willing to participate in environmentally friendly practices. Therefore, small and medium enterprises should enlighten their staff to practice green behaviour, give them what they need and empower them to be change drivers that will trigger sustainability throughout the organisations.
METHODS: This was an individual participant data meta-analysis of the prognostic performance of histologically assessed fibrosis stage (F0-4), liver stiffness measured by vibration-controlled transient elastography (LSM-VCTE), fibrosis-4 index (FIB-4), and NAFLD fibrosis score (NFS) in patients with NAFLD. The literature was searched for a previously published systematic review on the diagnostic accuracy of imaging and simple non-invasive tests and updated to Jan 12, 2022 for this study. Studies were identified through PubMed/MEDLINE, EMBASE, and CENTRAL, and authors were contacted for individual participant data, including outcome data, with a minimum of 12 months of follow-up. The primary outcome was a composite endpoint of all-cause mortality, hepatocellular carcinoma, liver transplantation, or cirrhosis complications (ie, ascites, variceal bleeding, hepatic encephalopathy, or progression to a MELD score ≥15). We calculated aggregated survival curves for trichotomised groups and compared them using stratified log-rank tests (histology: F0-2 vs F3 vs F4; LSM: <10 vs 10 to <20 vs ≥20 kPa; FIB-4: <1·3 vs 1·3 to ≤2·67 vs >2·67; NFS: 0·676), calculated areas under the time-dependent receiver operating characteristic curves (tAUC), and performed Cox proportional-hazards regression to adjust for confounding. This study was registered with PROSPERO, CRD42022312226.
FINDINGS: Of 65 eligible studies, we included data on 2518 patients with biopsy-proven NAFLD from 25 studies (1126 [44·7%] were female, median age was 54 years [IQR 44-63), and 1161 [46·1%] had type 2 diabetes). After a median follow-up of 57 months [IQR 33-91], the composite endpoint was observed in 145 (5·8%) patients. Stratified log-rank tests showed significant differences between the trichotomised patient groups (p<0·0001 for all comparisons). The tAUC at 5 years were 0·72 (95% CI 0·62-0·81) for histology, 0·76 (0·70-0·83) for LSM-VCTE, 0·74 (0·64-0·82) for FIB-4, and 0·70 (0·63-0·80) for NFS. All index tests were significant predictors of the primary outcome after adjustment for confounders in the Cox regression.
INTERPRETATION: Simple non-invasive tests performed as well as histologically assessed fibrosis in predicting clinical outcomes in patients with NAFLD and could be considered as alternatives to liver biopsy in some cases.

METHODS: A quantitative cross-sectional study was conducted conveniently among 381 individuals from the low-income group in Selangor, Malaysia. The remote data collection (RDC) method was used to gather data. Validated interviewer-rated questionnaires were used to collect data via phone call. Respondents included in the study were 18 years and older. A normality of numerical variables were assessed using Shapiro-Wilk test. Univariate analysis of all variables was performed, and results were presented as means, mean ranks, frequencies, and percentages. Mann-Whitney U test or Kruskal Wallis H test was applied for the comparison of DHL and health information seeking behavior with characteristics of the participants. Multivariate linear regression models were applied using DHL as dependent variable and health information seeking behavior as independent factors, adjusting for age, gender, marital status, educational status, employment status, and household income.
RESULTS: The mean age of the study participants was 38.16 ± 14.40 years ranging from 18 to 84 years. The vast majority (94.6%) of participants stated that information seeking regarding COVID-19 was easy or very easy. Around 7 percent of the respondents cited reading information about COVID-19 on the internet as very difficult. The higher mean rank of DHL search, content, reliability, relevance, and privacy was found among participants who were widowed, had primary education, or unemployed. An inverse relationship was found between overall DHL and confidence in the accuracy of the information on the internet regarding COVID-19 (β = -2.01, 95% CI = -2.22 to -1.79).
CONCLUSION: It is important to provide support to lower-income demographics to assist access to high-quality health information, including less educated, unemployed, and widowed populations. This can improve overall DHL.
METHODS: We analyzed data from 91 seroprevalence surveys and sentinel surveillance among antenatal care clinic (ANC) attendees using model-based geostatistical methods to produce estimates of HIV prevalence across 43 countries in SSA, from years 2000 to 2018, at a 5 × 5-km resolution and presented among second administrative level (typically districts or counties) units.
RESULTS: We found substantial variation in HIV prevalence across localities, ages, and sexes that have been masked in earlier analyses. Within-country variation in prevalence in 2018 was a median 3.5 times greater across ages and sexes, compared to for all adults combined. We note large within-district prevalence differences between age groups: for men, 50% of districts displayed at least a 14-fold difference between age groups with the highest and lowest prevalence, and at least a 9-fold difference for women. Prevalence trends also varied over time; between 2000 and 2018, 70% of all districts saw a reduction in prevalence greater than five percentage points in at least one sex and age group. Meanwhile, over 30% of all districts saw at least a five percentage point prevalence increase in one or more sex and age group.
CONCLUSIONS: As the HIV epidemic persists and evolves in SSA, geographic and demographic shifts in prevention and treatment efforts are necessary. These estimates offer epidemiologically informative detail to better guide more targeted interventions, vital for combating HIV in SSA.
METHODS: The KGOG 1047/DEBULK trial is a phase III, multicenter, randomized clinical trial involving patients with bulky or multiple LN metastases in cervical cancer IIICr. This study will include patients with a short-axis diameter of a pelvic or para-aortic LN ≥2 cm or ≥3 LNs with a short-axis diameter ≥1 cm and for whom CCRT is planned. The treatment arms will be randomly allocated in a 1:1 ratio to either receive CCRT (control arm) or undergo surgical debulking of bulky or multiple LNs before CCRT (experimental arm). CCRT consists of extended-field external beam radiotherapy/pelvic radiotherapy, brachytherapy and LN boost, and weekly chemotherapy with cisplatin (40 mg/m²), 4-6 times administered intravenously. The primary endpoint will be 3-year progression-free survival rate. The secondary endpoints will be 3-year overall survival rate, treatment-related complications, and accuracy of radiological diagnosis of bulky or multiple LNs.

MATERIALS AND METHODS: Retrospective analysis was conducted on patients undergoing SSB-RIRS from January 2015 to June 2022 across 21 centers worldwide. Three months perioperative and postoperative outcomes were recorded, focusing on complications and stone-free rates (SFR).
RESULTS: A total of 733 patients were included, with 415 in group 1 (Ho:YAG) and 318 in group 2 (TFL). Both groups have similar demographic and stone characteristics. Group 1 had more incidence of symptomatic pain or hematuria (26.5% vs. 10.4%). Operation and lasing times were comparable. The use of baskets was higher in group 1 (47.2% vs. 18.9%, p<0.001). Postoperative complications and length of hospital stay were similar. Group 2 had a higher overall SFR. Multivariate regression analysis indicated that age, presence of stone at the lower pole, and stone diameter were associated with lower odds of being stone-free bilaterally, while TFL was associated with higher odds.
CONCLUSIONS: Our study shows that urologists use both lasers equally for SSB-RIRS. Reintervention rates are low, safety profiles are comparable, and single-stage bilateral SFR may be better in certain cases. Bilateral lower pole and large-volume stones have higher chances of residual fragments.
METHODS: A household-based cross-sectional study was conducted in March 2024 in six Semai sub-ethnic indigenous villages in Pos Lenjang, Kuala Lipis, Pahang. A structured questionnaire was administered to randomly selected individuals (≥ 12 years old) to collect data on sociodemographic characteristics and KAP. Data were analysed using descriptive statistics and predictors of KAP were determined using logistic regression. A p-value less than 0.05 was considered statistically significant.
RESULTS: A total of 267 individuals from 160 households were interviewed. Nearly half had good knowledge (49.4%) and positive attitudes (54.3%) towards malaria, with high practice scores for prevention and control (83.1%). Multivariate logistic regression analysis showed higher odds of good knowledge in those aged 40-59 years (adjusted odd ratio [aOR] = 6.90, p = 0.034), with primary (aOR = 2.67, p = 0.015) or secondary education (aOR = 2.75, p = 0.019), and with previous malaria history (aOR = 5.14, p
METHODS: Positive blood cultures from hospitalized patients in a Malaysian tertiary center between April 2022 and March 2023 were reviewed. A total of 137 clinical isolates of Escherichia coli (E.coli), Klebsiella pneumoniae (K.pneumoniae), and Klebsiella oxytoca were included. The antibiotic susceptibility and ESBL phenotypes were determined by disk diffusion method and the identification of genotypes by multiplex polymerase chain reaction. The clinical characteristics and outcome information were extracted by reviewing patients' medical records to evaluate the clinical significance of the ESBL genotype-positive but phenotype-negative isolates in bacteremia.
RESULTS: All 137 isolates were positive for at least one genotype (bla CTX-M, n = 71, 51.8%; bla SHV, n = 87, 63.5%; bla TEM, n = 95, 69.3%; bla OXA-1, n = 38, 27.7%). While bla CTX-M was proportionately higher in the ESBL phenotype-positive isolates than ESBL phenotype-negative isolates (33/37, 89.2% vs 38/100, 38%; p < 0.001), more than half of those harboring bla CTX-M remained susceptible to third-generation cephalosporins (3GC). The sensitivity (Sen) of bla CTX-M for ESBL phenotypes prediction was 89.19% (95% confidence interval [CI], 74.58 - 96.97%); however, specificity (Sp) was low (46.47%; 95% CI 39.75 - 53.32). The patient characteristics were similar among 98 ESBL phenotype-negative cases, except that the non-bla CTX-M carrier group had significantly more renal impairment (0/37 vs 7/61, p = 0.043) and gastrointestinal sources of bacteremia (9/37 vs 27/61, p = 0.047). No differences were observed in infection severity, in-hospital mortality, and length of stay (LOS) between the bla CTX-M and non-bla CTX-M carrier groups.
CONCLUSION: The current study provides insight into the gene carriage in E.coli and Klebsiella species clinical isolates, including bla CTX-M genotypes in antibiotic-susceptible strains from a Malaysian hospital. The ESBL encoding genotypes such as bla CTX-M presented substantially beyond one-third of the ESBL phenotype-negative or 3GC susceptible E.coli and K.pneumoniae isolated from bloodstream infection. Although clinical outcomes were not worsened with bla CTX-M genotype-positive but ESBL phenotype-negative isolates in bacteremia, the potential implications for AMR spread deserve further investigation.
MATERIALS AND METHODS: This study was carried out on 50 human cadavers including dissected specimens (25 males and 25 females) the kidneys, renal pelvis, and ureters along with their arteries were exposed and the anomalous abnormalities of the renal pelvis and ureters existing with accessory renal arteries were observed. Photographs of the anomalous and developmental variations were taken for proper documentation.
RESULTS: Among the 50 cadavers studied, unilateral double ureters were found in 5 cadavers (10%), rare bilateral "S-"shaped loop of ureter with quadruple uretic constrictors in the abdominal segment of the ureter was observed in one female cadaver (2%), accessory or aberrant renal arteries were found in 15 cadavers (30%), hydronephrosis involving the renal pelvis and ureters was observed in 9 cadavers (18%). Interestingly, this prevalence was higher among males (28%) compared to females (8%). Moreover, the occurrence of bilateral hydronephrosis of the kidneys, renal pelvis, and ureters was identified in a single male cadaver, representing 2% of the sample. Notably, the prevalence of double ureter, hydronephrosis accompanied by congenital double and triple accessory renal arteries was documented in nine cadavers, accounting for 18% of the cohort.
CONCLUSION: Anatomical and developmental variations of the ureters, renal pelvis, and renal vasculature, as well as their relationships to surrounding structures, hold clinical significance due to their impact on various surgical procedures, including kidney transplantation, abdominal aorta reconstruction, interventional radiology, and urologic operations. Therefore, identifying these potential developmental variations is essential for effective surgical management to preserve renal function and ensure optimal patient outcomes.
AIMS: Accordingly, this present study was designed to evaluate the abnormal ossified structures anatomically and radiologically within and around the foramen transversarium.
MATERIALS AND METHODS: This study was conducted on 182 (26 sets of cervical vertebrae) dried human cervical vertebrae obtained from the respective departments of anatomy and on 190 (95 males and 95 females) adult patients who visited the radiology department for neck-related problems such as stiff neck, neck/shoulder pain, dizziness, vertigo, imbalance, visual disturbances, and cognitive impairment.
RESULTS: Among 182 examined cervical vertebrae, unilateral complete accessory foramen transversarium was found in 23 vertebrae (12.63%), bilateral complete in 19 (10.44%), bilateral incomplete in 6 (3.29%), unilateral complete double in 4 (2.19%), and unilateral complete absence of foramen transversarium in 3 (1.64%). Stenosis due to aberrant osteophytes was noted in 9 vertebrae (4.9%). Out of 190 patients, three males presented with cervical kyphosis, severe spinal canal stenosis, and spinal cord compression due to ossification of the posterior longitudinal ligament and osteophyte complexes at C3-C6, with the most significant compression at C5-C6.
CONCLUSION: A thorough understanding of abnormal ossifications in and around the foramen transversarium is crucial for the management of cervical spine disorders; imaging modalities such as X-ray, computed tomography, and magnetic resonance imaging are crucial for recognizing and intervening in these cases, which is essential to prevent adverse neurological outcomes associated with vertebral artery involvement.
METHODS: A retrospective cohort study was performed. Case records of consecutive patients with culture-positive melioidosis who underwent computed tomography (CT) thorax from January 1, 2018-February 28, 2022, were reviewed.
RESULTS: 486 culture-positive melioidosis patients were identified, of which 70 underwent CT thorax. 41 patients demonstrating mediastinal involvement were included in the final analysis, of which four were mediastinal collections, while the rest were classified into those with necrotic or matted appearances, and subcentimeter and larger than 1 cm. Culture-positivity was proven from blood in 83 % of patients (n = 34), with the remaining from chest wall pus, neck abscess pus, sputum, liver abscess, seminal vesicle, pleural, pericardial and peritoneal fluid. The most commonly associated pulmonary manifestations were consolidation and pleural effusion. Half had diabetes; a quarter had chronic kidney disease, while one had syphilis. Exposure to soil was present in six patients: quarry (n = 1), construction (n = 2), farmer (n = 1), living environment (n = 2). Seven patients succumbed before the end of 6-week intensive phase antibiotic treatment.
CONCLUSION: Mediastinal melioidosis is a spectrum with multiple overlapping features consisting of necrosis, matted lymph nodes, multiseptated and non-septated collections. Further studies will elucidate the prognostic implications of mediastinal melioidosis.
