Femoral fracture in an amputation stump.

Presentation: We report a case of a 60-year-old male with bilateral lower limb amputations who sustained a fracture to his right residual femur after weight bearing on his prosthetic leg during therapy. This was attributed to his raised body mass index that fell in the morbidly obese category. Diagnosis: Patient was referred for orthopaedic management and reviewed by the multidisciplinary prosthetic rehabilitation team following the fracture recovery. Treatment: He was deemed unsuitable for further prosthetic usage and ultimately referred to the national weight management service and the bariatric team. Discussion: Fracture of the residual limb in an amputee is not a common occurrence. There is a scarcity of information regarding fractures in an amputation stump of obese individuals. This is an unusual case which highlights the significance of body weight on lower limb prosthetic usage, impact on rehabilitation and the need to address weight management at an earlier stage post amputations.

Exploring the therapeutic and prophylactic potential of bedaquiline in leprosy.

Leprosy remains a significant public health concern despite major strides in treatment and control efforts. The Global Leprosy Strategy 2021-2030 and the National Strategic Plan for Leprosy 2023-2027 majorly focus on facilitating action to reach the goal of zero leprosy. Exploration of new treatment regimens is emphasized as one of the verticals of the multipronged approach for reaching the aforementioned goals. This becomes particularly pertinent in the wake of growing evidence for resistance to the drugs currently being used in the management of leprosy. Repurposed molecules present a very good approach in this direction. The present review aims to explore the potential of bedaquiline, a drug used for multidrug-resistant tuberculosis, as a potential addition to the therapeutic armamentarium of leprosy. Through this narrative review, the authors attempt to look into the available proof of concept, clinical evidence, potential risks, and possible ways forward with bedaquiline in leprosy.

Adjuvant immunotherapy in high-risk muscle invasive urothelial carcinoma: A systematic review and meta-analysis of randomized clinical trials.

Despite surgical resection, many patients with muscle invasive urothelial carcinoma (MIUC) experience recurrence. Adjuvant immune checkpoint inhibition (ICI) following radical resection in patients with MIUC demonstrates disparate outcomes among phase III randomized controlled trials (RCTs). Our objective was to synthesize available data regarding the disease-free survival (DFS) benefit of adjuvant ICIs for patients with MIUC and evaluate the overall safety profile of ICIs in this setting. The protocol was registered with PROSPERO, CRD42022352587. We searched MEDLINE, Embase, CENTRAL, and relevant conference proceedings from inception up to January 29, 2024. Only phase III RCTs comparing adjuvant ICI versus placebo/observation were selected. Study screening and selection, along with data extraction was performed in duplicate according to a predefined registered protocol. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was used. Quality assessment was performed using the Cochrane risk-of-bias (RoB 2) tool for randomized trials. The primary and secondary endpoints were DFS and serious adverse events, respectively. All outcomes were analyzed using random-effects meta-analysis owing to inter-study heterogeneity. Sensitivity and subgroup analyses were performed to identify potential sources of heterogeneity. A priori defined subgroups of interest included positive program death-ligand 1 (PD-L1) expression, previous use of neoadjuvant chemotherapy (NAC), primary tumor origin, pathologic lymph node status, and baseline Eastern Cooperative Oncology Group performance status. Pooled results across the 3 RCTs (2,220 patients) demonstrated significantly improved DFS for patients treated with ICI in the intention-to-treat cohorts (HR 0.76, 95% CI 0.65-0.90). There was considerable clinical and statistical heterogeneity (I2 = 44%) due to differences in inclusion criteria and interventions. Overall, there was a low risk of bias among the RCTs. Regarding subgroup analyses, there was significant benefit among patients with negative PD-L1 expression (HR 0.76, 95% CI 0.64-0.90), those who received prior NAC (HR 0.69, 95% CI 0.52-0.91), and patients with lower tract (HR 0.71, 95% CI 0.55-0.92) but not upper tract disease (HR 1.21, 95% CI 0.87-1.68). This pooled analysis of DFS and safety provides support for ICI utilization in the setting of high-risk resected MIUC.

Assessment of fatty acid composition and amino acid profiles of three important fresh water fish species native to river Indus Pakistan.

This study was carried out to analyze the fatty acid and amino acid compositions of three economically important freshwater fish species, Mali (Wallago attu), Raho (Labeo rohita), and Mahseer (Tor putitora), indigenous to Indus River, Pakistan.. Amino acid profiling was done by high-performance liquid chromatography (HPLC) while gas chromatography (GC) was used for fatty acid analysis. Glutamic acid, aspartic acid, arginine, alanine, leucine, lysine and isoleucine were the most predominant amino acid while palmitic acid (C16:0), oleic acid (C18:1c), palmitoliec acid (C16:1c), linolenic acids (C18:2c) and docosahexaenoic acids (DHA C22:6) were the notable fatty acids present in these species. Our results indicated that all species have comparable nutritional composition and are good source of healthy human diet. Our findings will help the people to make informed choice while selecting fish for consumption and will pave the way for future researchers in planning new strategies to enhance the growth and production of commercial fish species. It will also be helpful for theFrom the current finding it was concluded that all fish species under discussion are rich in amino acids and fatty acids. These species contain essential amino acids and important fatty acid such as omega3 and omega 6, thus raising the nutritional quality of these species.

Human NQO1 as a Selective Target for Anticancer Therapeutics and Tumor Imaging.

Human NAD(P)H-quinone oxidoreductase1 (HNQO1) is a two-electron reductase antioxidant enzyme whose expression is driven by the NRF2 transcription factor highly active in the prooxidant milieu found in human malignancies. The resulting abundance of NQO1 expression (up to 200-fold) in cancers and a barely detectable expression in body tissues makes it a selective marker of neoplasms. NQO1 can catalyze the repeated futile redox cycling of certain natural and synthetic quinones to their hydroxyquinones, consuming NADPH and generating rapid bursts of cytotoxic reactive oxygen species (ROS) and H2O2. A greater level of this quinone bioactivation due to elevated NQO1 content has been recognized as a tumor-specific therapeutic strategy, which, however, has not been clinically exploited. We review here the natural and new quinones activated by NQO1, the catalytic inhibitors, and the ensuing cell death mechanisms. Further, the cancer-selective expression of NQO1 has opened excellent opportunities for distinguishing cancer cells/tissues from their normal counterparts. Given this diagnostic, prognostic, and therapeutic importance, we and others have engineered a large number of specific NQO1 turn-on small molecule probes that remain latent but release intense fluorescence groups at near-infrared and other wavelengths, following enzymatic cleavage in cancer cells and tumor masses. This sensitive visualization/quantitation and powerful imaging technology based on NQO1 expression offers promise for guided cancer surgery, and the reagents suggest a theranostic potential for NQO1-targeted chemotherapy.

Unveiling diagnostic prowess: a comparative study of exercise treadmill test and CT coronary in coronary artery disease detection in Pakistan (2021-2023).

Coronary Artery Disease (CAD) is a global health concern, with diagnostic modalities and risk factors that exhibit regional variations. This study, conducted at the Islamabad Diagnostic Center, Pakistan, aimed to provide a comprehensive assessment of CAD prevalence, severity, and associated risk factors, while also evaluating the diagnostic accuracy of Computed Tomography Coronary Test (CTT) and Exercise Treadmill Test (ETT) in a cohort of 2909 patients. Among the patients assessed via CT Coronary scans, CAD was universally observed, presenting with varying degrees of severity. Our findings indicated that 24.5% of patients had mild CAD, 28.6% exhibited mild to moderate CAD, 16.3% were diagnosed with moderate CAD, 18.4% demonstrated moderate to severe CAD, and 20.4% displayed severe CAD. This spectrum underscores the diverse nature of CAD within the study population. In addition to CTT, we conducted a detailed evaluation of ETT results in 49 patients. These results revealed that 55.1% of patients tested positive for ischemia during the exercise test, emphasizing the prevalence of cardiac stress and underlying CAD. Conversely, 32.7% of patients exhibited negative ETT results, indicating favorable cardiac tolerance during physical activity. A subset of patients yielded non-diagnostic or inconclusive results, necessitating further clinical assessment. Disease history analysis showed a dichotomy within the cohort, with 20.4% having a known medical history and 79.6% possessing an unknown disease history, highlighting the importance of comprehensive medical records in clinical practice. Hypertension, a critical cardiovascular risk factor, was identified in 87.8% of patients, underscoring its significance. Smoking history displayed notable variation, with 69.4% categorized as smokers, 14.3% as ex-smokers, and 10.2% as non-smokers. Lipid profile analysis indicated that 69.4% of patients had abnormal lipid levels. To assess the diagnostic accuracy of CTT and ETT, we calculated Positive Predictive Values (PPV) and Negative Predictive Values (NPV). CTT exhibited a PPV of approximately 5.99% and an NPV of approximately 4.40%, whereas ETT displayed a higher PPV of around 26.44% and a substantially higher NPV of about 49.24%. This study offers valuable insights into CAD prevalence, severity, and associated risk factors in a Pakistani cohort, emphasizing the importance of holistic risk assessment and tailored interventions in clinical practice. Our findings also highlight the diagnostic utility of ETT in CAD assessment.

Biomedical properties, characterization of seaweeds species and antimicrobial activity.

Marine organisms produce a variety of compounds with pharmacological activities. In order to better comprehend the medicinal value of five particular seaweed orders Ulvales (Ulva intestinalis), Bryopsidales (Codium decorticatum), Ectocarpales (Iyengaria stellata), Dictyotales (Spatoglossum aspermum) and Gigartinales (Hypnea musciformis), a bioactive analysis including the screening of phytochemical components, antioxidant and antimicrobial activities was the aim of the investigation. The species include U. intestinalis was collected from Sandspit, while C. decorticatum, I. stellata, S. aspermum, and H. musciformis were gathered from Buleji. These species evaluated for their ability to inhibit human infectious gram positive pathogens Staphylococcus aureus, Staphylococcus epidermidis as well as gram negative bacteria Escherichia coli. Additionally vegetable pathogen Fusarium oxysporum, and fruit pathogens (Aspergillus niger and Aspergillus flavus) were evaluated to determine the zone of inhibition. Two organic solvents, ethanol and methanol, were used to prepare seaweed extract. The disc diffusion method was utilized to quantify the zone of inhibition and the DPPH method was employed to measure the antioxidant activity. The study unveiled various phyto-constituents in the tested seaweeds, with flavonoids, tannins, and proteins found in all selected species, while saponins, terpenoids, and carbohydrates were absent in I. stellata and S. aspermum. Notably, ethanolic extracts of I. stellata and S. aspermum demonstrated superior higher antioxidant activity, with increasing percentages of inhibition from 1 to 6 mg/ml. Furthermore, the findings indicated that the ethanolic extract of U. intestinalis displayed the highest resistance against F. oxysporum and A. flavous among other seaweeds. Meanwhile, the ethanolic extract of C. decorticatum exhibited the highest resistance against A. Niger. Additionally, the ethanolic extract of I. stellata and H. musciformis displayed the highest resistance against the gram-negative bacteria E. coli and the gram-positive bacteria S. epidermidis, whereas the methanolic extract of U. intestinalis demonstrated the highest resistance against the gram-positive bacteria S. aureus. The findings of this investigation show that a range of bioactive compounds with antioxidant properties are involved in the antimicrobial activities of disease-causing pathogens.

Impact of Timing of Immunotherapy and Cytoreductive Nephrectomy in Metastatic Renal Cell Carcinoma: Real-World Data on Survival Outcomes from the CKCis Database.

Immunotherapy-based systemic treatment (ST) is the standard of care for most patients diagnosed with metastatic renal cell carcinoma (mRCC). Cytoreductive nephrectomy (CN) has historically shown benefit for select patients with mRCC, but its role and timing are not well understood in the era of immunotherapy. The primary objective of this study is to assess outcomes in patients who received ST only, CN followed by ST (CN-ST), and ST followed by CN (ST-CN). The Canadian Kidney Cancer information system (CKCis) database was queried to identify patients with de novo mRCC who received immunotherapy-based ST between January 2014 and June 2023. These patients were classified into three categories as described above. Cox proportional hazards models were used to assess the impact of the timing of ST and CN on overall survival (OS) and progression-free survival (PFS), after adjusting for the International Metastatic RCC Database Consortium (IMDC) risk group, age, and comorbidities. Best overall response and complications of ST and CN for these cohorts were collected. A total of 588 patients were included in this study: 331 patients received ST only, 215 patients received CN-ST, and 42 patients received ST-CN. Patient and disease characteristics including age, gender, performance status, IMDC risk category, comorbidity, histology, type of ST, and metastatic sites are reported. OS analysis favored patients who received ST-CN (hazard ratio [HR] 0.30, 95% confidence interval [CI] 0.13-0.68) and CN-ST (HR 0.68, CI 0.47-0.97) over patients who received ST only. PFS analysis showed a similar trend for ST-CN (HR 0.45, CI 0.26-0.77) and CN-ST (HR 0.9, CI 0.68-1.17). This study examined baseline features and outcomes associated with the use and timing of CN and ST using real-world data via a large Canadian real-world cohort. Patients selected to receive CN after ST demonstrated improved outcomes. There were no appreciable differences in perioperative complications across groups. Limitations include the small number of patients in the ST-CN group and residual confounding and selection biases that may influence the outcomes in patients undergoing CN.

Identifying functional cortical plasticity after spinal tumour resection using navigated transcranial magnetic stimulation.

Our aim was to investigate the effectiveness of navigated transcranial magnetic stimulation (nTMS) brain mapping to characterise preoperative motor impairment caused by an intradural extramedullary (IDEM) tumour and postoperative cortical functional reorganisation. Preoperative and 1-year follow-up clinical, radiological and nTMS data from a case of thoracic spinal meningioma that underwent surgical resection of the lesion were collected and compared. A 67-year-old patient presented with severe progressive thoracic myelopathy (hypertonic paraparesis, clonus, insensate urinary retention) secondary to an IDEM tumour. Initial nTMS assessment showed bilateral upper limb representation with no positive responses for both lower limbs. He underwent successful surgical resection for his IDEM (meningioma WHO grade 1). At 1-year follow-up, the patient's gait was improved and his bladder function normalised. nTMS documented positive responses for both upper and lower limbs and a decrease in the area (right side: 1.01 vs 0.39cm2; left side: 1.92 vs 0.81cm2) and volume (right side: 344.2 vs 42.4uVcm2; left side: 467.1 vs 119uVcm2) of cortical activation for both upper limbs, suggesting a functional reorganisation of the motor areas after tumour resection. nTMS motor mapping and derived metrics can characterise preoperative motor deficit and cortical plasticity during follow-up after IDEM resection.

SARS-CoV-2 clearance in term of Cycle Threshold (Ct) during first two waves of COVID-19 in Pakistan: a phenomenon of delayed viral clearance post-corticosteroid treatment.

SARS-CoV-2 is recently emerged virus, which caused millions of deaths, all over the world. To tackle COVID-19 pandemic, there is an utmost need for in-depth analysis of viral replication. We aimed to examine viral load in SARS-CoV-2 patients during first two waves of COVID-19 in Pakistan. 225,615 suspected subjects from 75 different regions of Pakistan were selected in the study. SARS-CoV-2 RNAs were detected via real time PCR. During first wave (period of June-July, 2020) of COVID-19 the prevalence of SARS-CoV-2 was 20.38%. However, during second wave (period of November-December, 2020) of COVID-19, the rate of prevalence was 9.41%. During first wave of COVID-19 96.31% of participants remained PCR positive for 14 to 21 days, 3.39% of subjects showed positive results for 22 to 35 days, while delayed Ct values were observed among 0.26% of participants for 36 to 49 days. However, during second wave of COVID-19 89.31% of the subjects exhibited symptoms and showed real-time PCR positive results for 14 to 21 days, 9.42% showed positive results for 22 to 35 days, while significantly delayed Ct value results were observed among 1.026% of participants for 36 to 63 days (3.95 times higher than first wave). In contrast to first wave of COVID-19, the factors that were different in second wave were neither viral (different strains) nor host (same population). But treatment factors changed significantly. As during second wave besides azithromycin, corticosteroid dexamethasone consumption was increased consequently causing delayed Ct value negativity. This suggests that corticosteroid treatment might be linked with delayed Ct value or viral clearance. This study is crucial for re-considering effective therapeutic options against COVID-19.

2022 TB programme review in Pakistan: strengthening governance, with better patient diagnosis and treatment.

BACKGROUND: In Pakistan, 84% of healthcare is provided by the private sector. We conducted an epidemiological and programme review for TB to document progress and guide further efforts. METHODS: Surveillance and data systems were assessed before analysing epidemiological data. We reviewed the programme at federal, provincial and peripheral levels and compiled national data along with WHO estimates to describe the evolution of epidemiological and programme indicators. RESULTS: In 2021, of the estimated number of TB cases, 55% of overall cases and 18% of drug-resistant cases were diagnosed and treated respectively. The contribution of the private sector in case detection increased from 30% in 2017 to 40% by 2021. For newly diagnosed pulmonary TB cases, the overall proportion of confirmed cases was 52%. In 2021, testing for rifampicin resistance among confirmed cases was 66% for new and 84% for previously treated patients. The treatment success rate exceeded 90% for drug susceptible TB. The main challenges identified were a funding gap (60% in 2021-2023), fragmented electronic systems for data collection and suboptimal coordination among provinces. CONCLUSIONS: The main challenges prevent further progress in controlling TB. By addressing these, Pakistan could improve coverage of interventions, including diagnosis and treatment. Bacteriological confirmation using recommended diagnostics also requires further optimisation.

CONTEXTE: Au Pakistan, le secteur privé assure 84% des services de santé. Une étude épidémiologique et programmatique a été réalisée sur la TB afin de recueillir des informations sur les avancées réalisées et de guider les actions à venir. MÉTHODES: Les systèmes de surveillance et de données ont été évalués préalablement à l'analyse des données épidémiologiques. Nous avons examiné le programme aux niveaux fédéral, provincial et local et compilé les données nationales ainsi que les estimations de l'OMS afin de décrire l'évolution des indicateurs épidémiologiques et du programme. RÉSULTATS: En 2021, environ 55% de l'ensemble cas de TB et 18% des cas résistants aux médicaments ont été diagnostiqués et traités respectivement. La contribution du secteur privé dans la détection des cas est passée de 30% en 2017 à 40% en 2021. La proportion totale de cas confirmés pour les nouveaux diagnostics de TB pulmonaire s'élevait à 52%. En 2021, les tests de résistance à la rifampicine parmi les cas confirmés s'élevaient à 66% pour les nouveaux patients et de 84% pour les patients déjà traités. Le taux de réussite du traitement a dépassé 90% pour la TB sensible aux médicaments. Les défis majeurs comprennent un manque de financement (60% pour la période 2021­2023), des systèmes électroniques de collecte de données fragmentés et une coordination insuffisante entre les provinces. CONCLUSIONS: Les défis majeurs entravent les avancées dans la lutte contre la TB. En les mettant en évidence, le Pakistan pourrait améliorer la portée des interventions, y compris le diagnostic et le traitement. Il est également essentiel d'optimiser la confirmation bactériologique en utilisant les diagnostics recommandés.

A social enterprise model for TB detection and treatment through the private sector in Pakistan.

BACKGROUND: Existing models to increase TB case notifications from the private sector in Pakistan are financially unsustainable and have achieved modest success due to limited coverage. OBJECTIVE: To evaluate the impact of a social enterprise model (SEM) intervention on TB case detection in Karachi, Pakistan, and to assess its financial sustainability. METHODS: Purpose-built centres were established within the private sector that integrated TB screening, diagnostics and treatment and operated 12 hours per day with convenient locations to improve access. TB services were offered free of cost, and revenue generation took place through user fees from other diagnostics. Private providers with a focus on the informal sector were engaged through community workers to generate screening referrals. RESULTS: Overall 171,488 people were screened and 18,683 cases were notified, including 197 individuals with drug-resistant TB. Annual TB notifications in Karachi increased from 18,105 in 2014 to a maximum of 25,840 (40% increase). The proportion of cases in Karachi notified by the centres grew to 27% in 2020. Commercial revenue reached USD288,065 and enabled operating cost recovery of 15%. Average cost per TB case notified was USD203. CONCLUSION: The SEM intervention contributed a large proportion of notifications in Karachi and achieved modest cost recovery.

CONTEXTE: Les modèles existants visant à augmenter les notifications de cas de TB par le secteur privé au Pakistan ne sont pas viables financièrement et n'ont obtenu qu'un succès modeste en raison d'une couverture limitée. OBJECTIF: Évaluer l'impact d'un modèle déntreprise sociale (SEM, pour l'anglais « social entreprise model ¼) sur la détection des cas de TB à Karachi, au Pakistan, et évaluer sa viabilité financière. MÉTHODES: Des centres spécialisés ont été créés dans le secteur privé. Ils intègrent le dépistage, le diagnostic et le traitement de la TB et fonctionnent 12 heures par jour dans des lieux adaptés afin dén faciliter l'accès. Les services de lutte contre la TB étaient gratuits et les recettes provenaient des frais d'utilisation des autres diagnostics. Des prestataires privés, axés sur le secteur informel, ont été engagés par l'intermédiaire d'agents communautaires pour orienter les patients vers les services de dépistage. RÉSULTATS: Au total, 171 488 personnes ont été dépistées et 18 683 cas ont été notifiés, dont 197 personnes atteintes de TB résistante aux médicaments. Les notifications annuelles de TB à Karachi sont passées de 18 105 en 2014 à un maximum de 25 840 (augmentation de 40%). La proportion de cas à Karachi notifiés par les centres est passée à 27% en 2020. Les recettes commerciales ont atteint 288 065 USD et ont permis un recouvrement des coûts déxploitation de 15%. Le coût moyen par cas de TB notifié était de 203 USD. CONCLUSION: L'intervention SEM a contribué à une grande proportion de notifications à Karachi et a permis un modeste recouvrement des coûts.

The Use of Artificial Intelligence in Endodontics.

Endodontics is the dental specialty foremost concerned with diseases of the pulp and periradicular tissues. Clinicians often face patients with varying symptoms, must critically assess radiographic images in 2 and 3 dimensions, derive complex diagnoses and decision making, and deliver sophisticated treatment. Paired with low intra- and interobserver agreement for radiographic interpretation and variations in treatment outcome resulting from nonstandardized clinical techniques, there exists an unmet need for support in the form of artificial intelligence (AI), providing automated biomedical image analysis, decision support, and assistance during treatment. In the past decade, there has been a steady increase in AI studies in endodontics but limited clinical application. This review focuses on critically assessing the recent advancements in endodontic AI research for clinical applications, including the detection and diagnosis of endodontic pathologies such as periapical lesions, fractures and resorptions, as well as clinical treatment outcome predictions. It discusses the benefits of AI-assisted diagnosis, treatment planning and execution, and future directions including augmented reality and robotics. It critically reviews the limitations and challenges imposed by the nature of endodontic data sets, AI transparency and generalization, and potential ethical dilemmas. In the near future, AI will significantly affect the everyday endodontic workflow, education, and continuous learning.

Chaos and bifurcations of a two-dimensional hepatitis C virus model with hepatocyte homeostasis.

In this paper, we delve into the intricate local dynamics at equilibria within a two-dimensional model of hepatitis C virus (HCV) alongside hepatocyte homeostasis. The study investigates the existence of bifurcation sets and conducts a comprehensive bifurcation analysis to elucidate the system's behavior under varying conditions. A significant focus lies on understanding how changes in parameters can lead to bifurcations, which are pivotal points where the qualitative behavior of the system undergoes fundamental transformations. Moreover, the paper introduces and employs hybrid control feedback and Ott-Grebogi-Yorke strategies as tools to manage and mitigate chaos inherent within the HCV model. This chaos arises due to the presence of flip and Neimark-Sacker bifurcations, which can induce erratic behavior in the system. Through the implementation of these control strategies, the study aims to stabilize the system and restore it to a more manageable and predictable state. Furthermore, to validate the theoretical findings and the efficacy of the proposed control strategies, extensive numerical simulations are conducted. These simulations serve as a means of confirming the theoretical predictions and provide insight into the practical implications of the proposed control methodologies. By combining theoretical analysis with computational simulations, the paper offers a comprehensive understanding of the dynamics of the HCV model and provides valuable insights into potential strategies for controlling and managing chaos in such complex biological systems.

Evaluating compliance with the care standard of proactively assessing bone health in patients with diabetes: a pilot audit of practice across Asia by the Asia Pacific Consortium on Osteoporosis (APCO).

This pilot audit explored how bone health is assessed patients with diabetes in diverse centres across Asia. Only 343 of 1092 (31%) audited patients had a bone health assessment, 27% of whom were diagnosed with osteoporosis. Quality improvement strategies are needed to address gaps in patient care in this area. PURPOSE: The Asia Pacific Consortium on Osteoporosis (APCO) Framework outlines clinical standards for assessing and managing osteoporosis. A pilot audit evaluated adherence to clinical standard 4, which states that bone health should be assessed in patients with conditions associated with bone loss and/or increased fracture risk; this report summarises the audit findings in patients with diabetes. A secondary aim was to assess the practicality and real-world use of the APCO bone health audit tool kit. METHODS: Eight centres across Asia participated in the pilot audit, selecting diabetes as the target group. Participants reviewed their practice records for at least 20 consecutively treated patients with the target condition. Questions covered routine investigations, bone health assessment, osteoporosis diagnosis, and patient referral pathways. Data were summarised descriptively. RESULTS: The participants represented public hospitals, university medical centres, and private clinics from India, Malaysia, Pakistan, Singapore, Taiwan, and Vietnam that see an estimated total of 95,000 patients with diabetes per year. Overall, only 343 of 1092 audited patients (31%) had a bone health assessment. Osteoporosis was subsequently diagnosed in 92 of 343 (27%) patients. CONCLUSION: Bone health was not assessed in most patients with diabetes. The results provide insight into current practices across diverse Asian centres and demonstrate the practical value of the audit tool kit. Participant feedback has been used to improve the tool kit. Results of this pilot audit are being used in the respective centres to inform quality improvement projects needed to overcome the gap in patient care.

Unveiling the occurrence of COVID-19 in a diverse Bangladeshi population during the pandemic.

Introduction: COVID-19 pandemic hit Bangladesh with relatively low intensity, unlike its neighbors India and European countries and USA. Methods: The present report included data of 8,480 individuals tested for COVID-19 RT-PCR of the workers and officials from readymade garments (RMG) industry in Chandra area in Gazipur. The present data looked into the clinic-demographic factors associated with the susceptibility of the condition. Result: The data elucidated the susceptibility of the individuals to SARS-CoV-2 based on age, gender, pre-existing health conditions, and the presence of symptoms. It was observed that individuals aged over 60 had the highest rate of COVID-19 positivity, and men exhibited a higher infection rate compared to women. Regardless of age, fever and cough were the most frequently reported symptoms. Two-thirds of the individuals included in this report appeared to be asymptomatic carriers. The prevalence of comorbidities among individuals who tested positive for COVID-19 was notably higher, and this exhibited a gender-specific pattern. Discussion: Although our study provides important epidemiological insights into the initial year of the pandemic among Bangladeshi populations, it can also add value for future drug and vaccine development. However, it is essential to acknowledge the limitations like - restriction of public movement, unavailability of vehicle yielding a selection bias, due to the lockdown conditions imposed owing to the pandemic and the diverse characteristics of the participants. The report emphasizes the significance of figuring out how age, gender, and underlying health conditions impact susceptibility to and transmission of COVID-19, thereby providing valuable insights for public health strategies and future research initiatives.

Needle Biopsy of Pleura in the Aetiological Diagnosis of Pleural Effusion.

Exudative pleural effusion appears as manifestation of underlying specific disease process and pleural biopsy is usually enough to find out the underlying causative disease. The aim of the study was to find out the efficacy of needle biopsy of pleura in the aetiological diagnosis of pleural effusion. This cross-sectional study was conducted for a period of one year from January 2008 to December 2008 in the Department of Medicine, Shaheed Ziaur Rahman Medical College Hospital, Bogura, Bangladesh enrolling 50 subjects with exudative pleural effusion. The cases with transudative pleural effusion were not included. Needle biopsy was done in all the cases. Histopathological reports of pleural biopsy specimen were correlated with other data and analyzed to detect the causes of effusion. Major incidence of malignant effusion occurred between 41 to 70 years of age. No malignant effusion was found before 30 years of age. Incidence of tuberculous and malignant pleural effusion was much more common in males than in females. Sensitivity and specificity of combined pleural biopsy and pleural fluid analysis in the diagnosis of pleural effusion was 97.06% and 100.% for tuberculosis and 81.82% and 100.0% for malignancy. The present study reveals that pleural biopsy was very effective method in the diagnosis of cause of pleural effusion.
