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.

Community- vs. hospital-based management of multidrug-resistant TB in Pakistan.

BACKGROUND Multidrug-resistant TB (MDR-TB) treatment takes 18-24 months and is complex, costly and isolating. We provide trial evidence on the WHO Pakistan recommendation for community-based care rather than hospital-based care.METHODS Two-arm, parallel-group, superiority trial was conducted in three programmatic management of drug-resistant TB hospitals in Punjab and Sindh Provinces, Pakistan. We enrolled 425 patients with MDR-TB aged >15 years through block randomisation in community-based care (1-week hospitalisation) or hospital-based care (2 months hospitalisation). Primary outcome was treatment success.RESULTS Among 425 patients with MDR-TB, 217 were allocated to community-based care and 208 to hospital-based care. Baseline characteristics were similar between the community and hospitalised arms, as well as in selected sites. Treatment success was 74.2% (161/217) under community-based care and 67.8% (141/208) under hospital-based care, giving a covariate-adjusted risk difference (community vs. hospital model) of 0.06 (95% CI -0.02 to 0.15; P = 0.144).CONCLUSIONS We found no clear evidence that community-based care was more or less effective than hospital-based care model. Given the other substantial advantages of community-based care over hospital based (e.g., more patient-friendly and accessible, with lower treatment costs), this supports the adoption of the community-based care model, as recommended by the WHO.

Preoperative systemic inflammation and perioperative myocardial injury: prospective observational multicentre cohort study of patients undergoing non-cardiac surgery.

BACKGROUND: Systemic inflammation is pivotal in the pathogenesis of cardiovascular disease. As inflammation can directly cause cardiomyocyte injury, we hypothesised that established systemic inflammation, as reflected by elevated preoperative neutrophil-lymphocyte ratio (NLR) >4, predisposes patients to perioperative myocardial injury. METHODS: We prospectively recruited 1652 patients aged ≥45 yr who underwent non-cardiac surgery in two UK centres. Serum high sensitivity troponin T (hsTnT) concentrations were measured on the first three postoperative days. Clinicians and investigators were blinded to the troponin results. The primary outcome was perioperative myocardial injury, defined as hsTnT≥14 ng L-1 within 3 days after surgery. We assessed whether myocardial injury was associated with preoperative NLR>4, activated reactive oxygen species (ROS) generation in circulating monocytes, or both. Multivariable logistic regression analysis explored associations between age, sex, NLR, Revised Cardiac Risk Index, individual leukocyte subsets, and myocardial injury. Flow cytometric quantification of ROS was done in 21 patients. Data are presented as n (%) or odds ratio (OR) with 95% confidence intervals. RESULTS: Preoperative NLR>4 was present in 239/1652 (14.5%) patients. Myocardial injury occurred in 405/1652 (24.5%) patients and was more common in patients with preoperative NLR>4 [OR: 2.56 (1.92-3.41); P<0.0001]. Myocardial injury was independently associated with lower absolute preoperative lymphocyte count [OR 1.80 (1.50-2.17); P<0.0001] and higher absolute preoperative monocyte count [OR 1.93 (1.12-3.30); P=0.017]. Monocyte ROS generation correlated with NLR (r=0.47; P=0.03). CONCLUSIONS: Preoperative NLR>4 is associated with perioperative myocardial injury, independent of conventional risk factors. Systemic inflammation may contribute to the development of perioperative myocardial injury. CLINICAL TRIAL REGISTRATION: NCT01842568.

Association between preoperative pulse pressure and perioperative myocardial injury: an international observational cohort study of patients undergoing non-cardiac surgery.

BACKGROUND: The management of elevated blood pressure before non-cardiac surgery remains controversial. Pulse pressure is a stronger predictor of cardiovascular morbidity in the general population than systolic blood pressure alone. We hypothesized that preoperative pulse pressure was associated with perioperative myocardial injury. METHODS: This is a secondary analysis of the Vascular Events in Non-cardiac Surgery Patients Cohort Evaluation (VISION) international cohort study. Participants were aged ≥45 yr and undergoing non-cardiac surgery at 12 hospitals in eight countries. The primary outcome was myocardial injury, defined using serum troponin concentration, within 30 days after surgery. The sample was stratified into quintiles by preoperative pulse pressure. Multivariable logistic regression analysis explored associations between pulse pressure and myocardial injury. We accounted for potential confounding by systolic blood pressure and other co-morbidities known to be associated with postoperative cardiovascular complications. RESULTS: One thousand one hundred and ninety-one of 15 057 (7.9%) patients sustained myocardial injury, which was more frequent amongst patients in the highest two preoperative pulse pressure quintiles {63-75 mm Hg, risk ratio (RR) 1.14 [95% confidence interval (CI): 1.01-1.28], P =0.03; >75 mm Hg, RR 1.15 [95% CI: 1.03-1.29], P =0.02}. After adjustment for systolic blood pressure, preoperative pulse pressure remained the dominant predictor of myocardial injury (63-75 mm Hg, RR 1.20 [95% CI: 1.05-1.37], P <0.01; >75 mm Hg, RR 1.25 [95% CI: 1.06-1.48], P <0.01). Systolic blood pressure >160 mm Hg was not associated with myocardial injury in the absence of pulse pressure >62 mm Hg (RR 0.67 [95% CI: 0.30-1.44], P =0.31). CONCLUSIONS: Preoperative pulse pressure >62 mm Hg was associated with myocardial injury, independent of systolic blood pressure. Elevated pulse pressure may be a useful clinical sign to guide strategies to reduce perioperative myocardial injury.

Preoperative heart rate and myocardial injury after non-cardiac surgery: results of a predefined secondary analysis of the VISION study.

BACKGROUND: Increased baseline heart rate is associated with cardiovascular risk and all-cause mortality in the general population. We hypothesized that elevated preoperative heart rate increases the risk of myocardial injury after non-cardiac surgery (MINS). METHODS: We performed a secondary analysis of a prospective international cohort study of patients aged ≥45 yr undergoing non-cardiac surgery. Preoperative heart rate was defined as the last measurement before induction of anaesthesia. The sample was divided into deciles by heart rate. Multivariable logistic regression models were used to determine relationships between preoperative heart rate and MINS (determined by serum troponin concentration), myocardial infarction (MI), and death within 30 days of surgery. Separate models were used to test the relationship between these outcomes and predefined binary heart rate thresholds. RESULTS: Patients with missing outcomes or heart rate data were excluded from respective analyses. Of 15 087 patients, 1197 (7.9%) sustained MINS, 454 of 16 007 patients (2.8%) sustained MI, and 315 of 16 037 patients (2.0%) died. The highest heart rate decile (>96 beats min(-1)) was independently associated with MINS {odds ratio (OR) 1.48 [1.23-1.77]; P<0.01}, MI (OR 1.71 [1.34-2.18]; P<0.01), and mortality (OR 3.16 [2.45-4.07]; P<0.01). The lowest decile (<60 beats min(-1)) was independently associated with reduced mortality (OR 0.50 [0.29-0.88]; P=0.02), but not MINS or MI. The predefined binary thresholds were also associated with MINS, but more weakly than the highest heart rate decile. CONCLUSIONS: Preoperative heart rate >96 beats min(-1) is associated with MINS, MI, and mortality after non-cardiac surgery. This association persists after accounting for potential confounding factors. CLINICAL TRIAL REGISTRATION: NCT00512109.

Day case Laparoscopic Cholecystectomy: experience at the Bangabandhu Sheikh Mujib Medical University.

Day case surgery offers convenience to the patients and cost saving to the healthcare institutes. In this prospective study, the authors reviewed their experience with day case Laparoscopic Cholecystectomy (LC) to determine its outcome in the government healthcare settings of Bangladesh. Selection criteria's for the day case LC were patients with symptomatic cholelithiasis with ASA (American Society of anesthesiologists) grade I or II, the availability of a responsible carer, absence of morbid obesity, low risk for concomitant presence of bile duct stones and domicile within Dhaka and around. Patients were admitted in the post operative ward as day case (DC) in the morning and were discharged on the next morning with a standard analgesia. Two hundred ten patients were admitted for LC as day cases over the last 7 years from October 2003 to October 2010 on the morning operation theatre lists. Five patients later required admission to the inpatient department for conversion to the open procedure. None of the patients was readmitted after discharge. Majority patients were followed up after 1st and 6th week. Two hundred seven patients attended for the follow up at the 1st week and 158 patients were reported for the 6th week. One hundred ninety six patients resumed their normal job or activities after one week. Patient's satisfaction was assessed by questionnaires. Two hundred five patients were either satisfied or very satisfied with the day-case procedure. It appears that for selected groups of patients, day-case LC can be safely done in government healthcare settings of Bangladesh with good patient satisfaction.

Radio-decontamination efficacy and safety studies on optimized decontamination lotion formulation.

Objective of the present study was to optimize decontamination lotion and to evaluate its relative decontamination efficacy using three radio-isotopes (Technetium-99m, Iodine-131 and Thallium-201) as contaminants with varying length of contaminant exposure (0-1h). Experiments were performed on Sprague Dawley rat's intact skin and human tissue equivalent models. Rat's hair was removed by using depilator after trimming with scissors. Relative decontamination efficacy of the optimized lotion was investigated and compared with water as control. Static counts were recorded before and after decontamination using single photon emission computed tomography (SPECT). Measured decontamination efficacy (DE) values were analyzed using one way ANOVA and Student's t-test (p value<0.05) and were found statistically significant. Decontamination efficacy of the lotion was observed to be 90 ± 5%, 80 ± 2% and 85 ± 2%, for the (131)I, (201)Tl and (99m)Tc radio-contaminants respectively on skin. Reduced contaminant removal was recorded for the skin which was cleaned by depilator (50-60%). Skin decontamination was found more efficacious for rat skin decontamination than the human tissue equivalent model. Decontamination efficacy of the lotion against (99m)Tc was recorded 70 ± 15% at 0-1h on the tissue equivalent model. In vitro chelation efficacy of the lotion was also established by using the instant thin layer chromatography-slica gel (ITLC-SG) and >95% of (99m)Tc was recorded. Neither erythema nor edema was scored in the primary skin irritancy test visually observed for two weeks.

Endoscopic para-thyroidectomy: a new approach.

Two patients (one male and one female) underwent endoscopic para-thyroidectomy for parathyroid adenoma at the Department of Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Three ports (one mid line and two laterals) were employed, a 10 mm telescope was used for the visualization and a harmonic scalpel was used for the dissection. To the best of our knowledge, there was no report of endoscopic para-thyroidectomy from Bangladesh. Both patients were fed on the first post operative day and discharged from the 4th and 8th operative day. Both patient's parathyroid hormone (PTH) level dropped to about one fourth the level in 12 to 20 minutes after enucleation (as compared to the immediate pre operative level). Endoscopic para-thyroidectomy appears to be a technically feasible patient friendly modality of treatment for the selected cases of para-thyroid pathology in experienced hand with excellent cosmetic outcome.

Life in conflict: Characteristics of Depression in Kashmir.

BACKGROUND: Mental, physical and social health, are vital strands of life that are closely interwoven and deeply interdependent. Mental disorders affect people of all countries and societies, individuals at all ages, women and men, the rich and the poor, from urban and rural environments. Depression is more likely following particular classes of experience - those involving conflict, disruption, losses and experiences of humiliation or entrapment. Many people living amidst the rages of conflict suffer from post-traumatic stress disorder. OBJECTIVE: To determine the characteristics of depression in the population in Kashmir where a low-intensity-conflict has been going on for the last seventeen years. METHODS: The non-combatant civilian population was surveyed. The Centre for Epidemiological Studies Depression (CES-D) Scale was used to measure symptoms of depression in community populations. RESULTS: Due to continuing conflict in Kashmir during the last 18 years there has been a phenomenal increase in psychiatric morbidity. The results reveal that the prevalence of depression is 55.72%. The prevalence is highest (66.67%) in the 15 to 25 years age group, followed by 65.33% in the 26 to 35 years age group. The difference in the prevalence of depression among males and females is significant. Depression is much higher in rural areas (84.73%) as compared to urban areas (15.26%). In rural areas the prevalence of depression among females is higher (93.10 %) as compared to males (6.8%). CONCLUSION: Mental health is an integral part of overall health and quality of life. Effective evidence-based programs and policies are available to promote mental health, enhance resilience, reduce risk factors, increase protective factors, and prevent mental and behavioural disorders. Innovative community-based health programmes which are culturally and gender appropriate and reaches out to all segments of the population need to be developed. Substantial and sustainable improvements can be achieved only when a comprehensive strategy for mental health which incorporates both prevention and care elements is adopted.

Results of emergency appendectomy for appendicular mass.

Emergency appendectomy was done on 1142 patients during the period of July 1990 to January 2003 to evaluate the results. Of which 656(57.44%) were male and 496(42.56%) were female. The mean age was 22.21+/-3.93 years (04-85 years). The duration of pain before admission was 3.05+/-0.94 days (01-17 days) and 708(62%) patients presented with palpable mass; ultrasonogram revealed additional lump in 114(9.98%) patients, rest of the lump (28.02%) was detected during operation. 342(30%) patients had appendix abscess and 228(19.96%) had loculated collection. Eight patients had tuberculosis and four had carcinoma in addition. All had appendicitis except two of which one patient had carcinoid tumor and one had enteric fever perforation. Operative time ranged from 15-85 minutes (29.38+/-3.19 minutes). The average hospital stay was 4.22+/-0.82 days (03-17 days). There was no failure, faecal fistula or death. The overall wound related complication was 22.86% of which 14.62% was very minor and overall intra abdominal complication was 4.12%. Persistent wound pain was in 43(3.87%) and hypertrophied scar was found in 05 (0.45%) patients. 05(0.45%) patients needed exploration for persistent sinus one of which was tuberculosis and remaining was due to suture material. Remote complications like RTI, UTI, and DVT was found in 04(0.35%) patients. There was no death, no faecal fistula and no failure. It seems that emergency appendectomy could safely be done in appendix mass without any increased risk of mortality and morbidity.
