Short- and medium-term longitudinal outcomes of children diagnosed with multisystem inflammatory syndrome in children - report from a single centre in Pakistan.

OBJECTIVE: To determine the short- and medium-term cardiac outcomes in children admitted with multisystem inflammatory syndrome in children at a tertiary care centre in Pakistan. METHODS: Children fulfilling the criteria for multisystem inflammatory syndrome and admitted to the hospital between April 2020 and March 2022 were enrolled in this prospective longitudinal cohort study. From admission to discharge, laboratory and cardiac parameters were recorded for all patients, who were subsequently followed up in clinics at various intervals. Data analysis was conducted using STATA version 15.0. RESULTS: A total of 51 children were included, with viral myocarditis (41.2%) and toxic shock syndrome (33.3%) being the most common phenotypes. The cardiovascular system was most commonly affected in 27 children (53%) with laboratory evidence of inflammation and myocardial injury with median and interquartile levels of ferritin 1169 (534-1704), C-reactive protein 83 (24-175), lactate dehydrogenase 468 (365-1270), N-terminal pro-B-type natriuretic peptide 8,656 (2,538-31,166), and troponin 0.16 (0.02-2.0).On admission, decreased left ventricular ejection fraction was observed in 58.8% of patients and impaired global longitudinal strain in 33.3%. At discharge, left ventricular ejection fraction had normalised in 83% of patients. Pericardial effusion resolved in all patients, and valvulitis resolved in 86% by 12 months. Paediatric ICU admission was required in 42 (82%) of patients with an overall mortality of 12% (n = 6). CONCLUSION: Our study finds high hospital mortality for multisystem inflammatory syndrome in children compared to 1-2% from previous studies. Yet, in Pakistan, surviving children with multisystem inflammatory syndrome show favourable short- to medium-term cardiac outcomes.

Neurodevelopmental outcomes following possible serious bacterial infection in early infancy in Karachi, Pakistan: a prospective cohort study.

BACKGROUND: Pakistan reports a significant burden of neonatal mortality, with infections as one of the major causes. We aim to assess the long-term impact of early infancy infections on neurodevelopmental outcomes during later childhood. METHODS: We conducted a prospective follow-up study of the cohort enrolled at the Karachi site of the Aetiology of Neonatal Infection in South Asia (ANISA) during 2019-2020. Children with a possible serious bacterial infection (based on the WHO IMCI algorithm) at early infancy were assessed for neurodevelopment at 6-9 years of age and compared with healthy controls. The Ten Questions (TQS) questionnaire, Strengths and Difficulties Questionnaire (SDQ), and Parent's Evaluation of Developmental Stage Assessment Level (PEDS: DM-AL) neurodevelopmental assessment tools, were administered and scored by the research staff who were blinded to the child's exposure status. Generalized Structural Equation Modelling (GSEM) was employed to verify relationships and associations among developmental milestones, anthropometry, and sociodemographic variables. RESULTS: A total of 398 children (241 cases and 157 controls) completed neurodevelopmental and growth assessments. Cases had a significantly higher rate of abnormal TQS scores (54.5% vs. 35.0%, p-value 0.001), greater delays in motor milestones (21.2% vs. 12.1%, p-value 0.02), lower fine motor skills (78.4 ± 1.4 vs. 83.2 ± 1.5, p-value 0.02). The receptive language skills were well-developed in both groups. According to the logistic regression model, exposure to infection during the first 59 days of life was associated with delayed TQS milestones (ß = -0.6, 95% CI -1.2,-0.04), TQS hearing domain (ß = -0.3, 95% CI: -1.2 to 0.7), PEDS: DM-AL fine motor domain (ß = -1.3, 95% CI: -4.4 to 1.7), PEDS: DM-AL receptive language development (ß = -1.1, 95% CI: -3.7 to 1.4) and child anthropometric measurements such as weight and height (ß = -0.2, 95% CI: -0.4 to 0.01 and ß = -0.2, 95% CI: -0.4 to -0.01, respectively). Early pSBI exposure was positively associated with PEDS: DM-AL self-help domain (ß = 0.6, 95% CI: -1.2 to 2.4) and SDQ-P overall score (ß = 0.02, 95% CI: -0.3 to 0.3). CONCLUSION: Children exposed to PSBI during early infancy have higher rates of abnormal development, motor delays, and lower fine motor skills during later childhood in Pakistan. Socioeconomic challenges and limited healthcare access contribute to these challenges, highlighting the need for long-term follow-ups with integrated neurodevelopment assessments.

Secondary attack rates and determinants of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) household transmission in Pakistan: A case-ascertained prospective, longitudinal study.

BACKGROUND: Households are considered ideal settings for studying the transmission dynamics of an infectious disease. METHODS: A prospective study was conducted, based on the World Health Organization FFX protocol from October 2020 to January,2021. Household contacts of laboratory-confirmed index cases were followed up for their symptomatic history, nasal swabs for RT-PCR,and blood samples for anti-SARS CoV-2 antibodies were collected at enrollment and days 7, 14 and 28. We estimated secondary attack rate (SAR), effective household case cluster size and determinants of secondary infection among susceptible household contacts using multivariable logistic regression. RESULTS: We enrolled 77 index cases and their 543 contacts. Out of these, 252 contacts were susceptible at the time of enrollment. There were 77 household clusters, out of which, transmission took place in 20 (25.9%) giving rise to 34 cases. The acquired secondary attack rate (SAR) was 14.0% (95% CI 9.0-18.0). The effective household case cluster size was 0.46 (95%CI 0.33,0.56). Reported symptoms of nausea and vomiting (aOR, 7.9; 95% CI, 1.4-45.5) and fatigue (aOR, 9.3; 95% CI, 3.8-22.7) were associated with SARS-CoV-2 transmission. CONCLUSIONS: We observed a low SARS-CoV-2 secondary attack rate in the backdrop of high seroprevalence and asymptomatic transmission among households in Karachi, Pakistan.

Environmental surveillance for COVID-19 using SARS-CoV-2 RNA concentration in wastewater - a study in District East, Karachi, Pakistan.

Background: Wastewater-based surveillance is used to track the temporal patterns of the SARS-CoV-2 virus in communities. Viral RNA particle detection in wastewater samples can indicate an outbreak within a catchment area. We describe the feasibility of using a sewage network to monitor SARS-CoV-2 trend and use of genomic sequencing to describe the viral variant abundance in an urban district in Karachi, Pakistan. This was among the first studies from Pakistan to demonstrate the surveillance for SARS-CoV-2 from a semi-formal sewage system. Methods: Four sites draining into the Lyari River in District East, Karachi, were identified and included in the current study. Raw sewage samples were collected early morning twice weekly from each site between June 10, 2021 and January 17, 2022, using Bag Mediated Filtration System (BMFS). Secondary concentration of filtered samples was achieved by ultracentrifugation and skim milk flocculation. SARS-CoV-2 RNA concentrations in the samples were estimated using PCR (Qiagen ProMega kits for N1 & N2 genes). A distributed-lag negative binomial regression model within a hierarchical Bayesian framework was used to describe the relationship between wastewater RNA concentration and COVID-19 cases from the catchment area. Genomic sequencing was performed using Illumina iSeq100. Findings: Among the 151 raw sewage samples included in the study, 123 samples (81.5%) tested positive for N1 or N2 genes. The average SARS-CoV-2 RNA concentrations in the sewage samples at each lag (1-14 days prior) were associated with the cases reported for the respective days, with a peak association observed on lag day 10 (RR: 1.15; 95% Credible Interval: 1.10-1.21). Genomic sequencing showed that the delta variant dominated till September 2022, while the omicron variant was identified in November 2022. Interpretation: Wastewater-based surveillance, together with genomic sequencing provides valuable information for monitoring the community temporal trend of SARS-CoV-2.

Early to mid-pregnancy HbA1c levels and its association with adverse pregnancy outcomes in three low middle-income countries in Asia and Sub-Saharan Africa.

BACKGROUND: Hyperglycemia during pregnancy leads to adverse maternal and fetal outcomes. Thus, strict monitoring of blood glucose levels is warranted. This study aims to determine the association of early to mid-pregnancy HbA1c levels with the development of pregnancy complications in women from three countries in South Asia and Sub-Saharan Africa. METHODS: We performed a secondary analysis of the AMANHI (Alliance for Maternal and Newborn Health Improvement) cohort, which enrolled 10,001 pregnant women between May 2014 and June 2018 across Sylhet-Bangladesh, Karachi-Pakistan, and Pemba Island-Tanzania. HbA1c assays were performed at enrollment (8 to < 20 gestational weeks), and epidemiological data were collected during 2-3 monthly household visits. The women were followed-up till the postpartum period to determine the pregnancy outcomes. Multivariable logistic regression models assessed the association between elevated HbA1c levels and adverse events while controlling for potential confounders. RESULTS: A total of 9,510 pregnant women were included in the analysis. The mean HbA1c level at enrollment was found to be the highest in Bangladesh (5.31 ± 0.37), followed by Tanzania (5.22 ± 0.49) and then Pakistan (5.07 ± 0.58). We report 339 stillbirths and 9,039 live births. Among the live births were 892 preterm births, 892 deliveries via cesarean section, and 532 LGA babies. In the multivariate pooled analysis, maternal HbA1c levels of ≥ 6.5 were associated with increased risks of stillbirths (aRR = 6.3, 95% CI = 3.4,11.6); preterm births (aRR = 3.5, 95% CI = 1.8-6.7); and Large for Gestational Age (aRR = 5.5, 95% CI = 2.9-10.6). CONCLUSION: Maternal HbA1c level is an independent risk factor for predicting adverse pregnancy outcomes such as stillbirth, preterm birth, and LGA among women in South Asia and Sub-Saharan Africa. These groups may benefit from early interventional strategies.

Mobile healthcare simulation units: a narrative review.

For healthcare professionals working and living in geographical isolation, there are few opportunities to maintain skills and knowledge, and to update themselves with recent advances in care compared to their citydwelling peers. It is known that within a short period and limited practice, clinical skills erode. A mobile healthcare simulation unit provides high-quality, technologicallyenhanced, convenient, and affordable training for healthcare professionals under expert supervision in any remote setting. The current narrative review was planned to summarise the outcomes and challenges related to developing and effectively utilising mobile healthcare simulation units as experienced globally. A literature search was performed on PubMed, Google Scholar and Cochrane databases for relevant articles published between 2000 and 2020, which resulted in 18 articles that were shortlisted and three major themes. The identification of common strengths, weaknesses and challenges will be a starting point for those engaged in planning and operating such a centre in any location.

Factors associated with medical students' career choices at a private university: a cross-sectional study.

This study aimed to identify the factors associated with students' career choices and the decision whether they wanted to be trained abroad or in Pakistan. The study utilised a cross-sectional design and was conducted between July 2021 and February 2022. An anonymous survey was distributed among the medical students at Aga Khan University, Karachi, Pakistan. All analysis was carried out using Stata 17. A total of 269 students participated in the study. The most sought-after specialties were surgery 68 (25.3%), medicine 25(9.3%), and paediatrics 14(5.2%), and the decision was highly influenced by positive mentors and lifestyle. In addition, 259 (96%) of the students expressed a desire to practice abroad for training due to higher financial prospects and quality of training. This study revealed that providing enthusiastic mentors may encourage medical students to pursue a broader range of specialties. Furthermore, there is a need for advances in postgraduate training and increase in salaries to restore trust in Pakistan's healthcare system.

Efficacy and Tolerability of Semaglutide in Patients With Type-2 Diabetes Mellitus: Experience of a Tertiary Care Hospital, Pakistan.

Background: Semaglutide, a Glucagon-like peptide 1 (GLP-1) is highly effective as an anti-diabetic medication along with additional benefits of significant reduction in cardiovascular events and weight. Objectives: There is a lack of reliable evidence confirming the benefits of Semaglutide in the Pakistani cohort. Our study aims to ascertain the efficacy of Semaglutide in the Pakistani cohort and patient satisfaction. Methods: An ambi-directional cohort study was conducted from August 2022 to January 2023 at The Aga Khan University Hospital, Karachi, Pakistan. A chart review was done for all patients with Type 2 diabetes who were prescribed Semaglutide, and baseline data was recorded. Patients were followed prospectively in the endocrinology clinics after at least 3 months for the change in HbA1c, BMI, adverse effects profile, treatment satisfaction questionnaire for medications (TSQM-9) and medication effect score. Mean + STD or median with IQR were computed for continuous data, while categorical variables and percentages were measured. The association between variables was assessed by applying the chi-square test. Results: A total of 112 patients were recruited who took the medication for at least 3 months. The mean age of the patients was 50.9 ± 10.5 years with 51.2% females. The mean difference in weight, body mass index, fasting blood glucose, HbA1c, and medication effect score were decreasing from baseline to follow-up (-4.0 kg, -1.5 kg/m2, -23.1 mg/dl, -1.2%, -0.4) respectively. A decrease in appetite was reported in 72.7% of the participants. The major adverse effects observed were dyspepsia (21.4%) followed by nausea (20.5%) and constipation (19.6%). Medication was discontinued in 9.8% of patients due to gastrointestinal side effects. The majority (72.3%) of patients were satisfied with their medication. Conclusion: Semaglutide is effective in reducing HbA1c and weight in Pakistani population with measurable tolerability and patient satisfaction.

Morbidity and treatment costs of cystic fibrosis in a middle-income country.

Introduction: : Asian children with cystic fibrosis (CF) managed in Malaysia have significant morbidity with limited access to life-sustaining treatments. We determined the morbidity and treatment cost of CF in a resource-limited country. Methods: This cross-sectional study included all children diagnosed with CF in our centre. Data on clinical presentation, genetic mutation, serial spirometry results and complications were collected. Out-of-pocket (OOP) and healthcare costs over 1 year were retrieved for patients who were alive. Cohen's d and odds ratio (OR) were used to determine the effect size. Results: Twenty-four patients were diagnosed with CF. Five patients died at a median (range) age of 18 (0.3-22) years. F508deletion (c. 1521_1523delCTT) was found in 20% of the alleles, while 89% of the variants were detected in nine patients. Body mass index (BMI) Z score was >-1.96 in 70.6% of patients. Two thirds (68%) were colonised with Pseudomonas aeruginosa, and this was associated with lower weight (P = 0.009) and BMI (P = 0.02) Z scores. Only 18% had FEV1 Z scores >-1.96. Early symptom onset (d = 0.74), delayed diagnosis (d = 2.07), a low FEF25-75 Z score (d = 0.82) and a high sweat conductance (d = 1.19) were associated with death. Inpatient cost was mainly from diagnostic tests, while medications contributed to half of the outpatient cost.Healthcare utilisation cost was catastrophic, amounting to 20% of the total income. Conclusion: Asian children with CF suffer significant complications such as low weight, low lung function and shortened lifespan. P. aeruginosa colonisation was frequent and associated with poor growth. Healthcare cost to parents was catastrophic.

Student experiences of simulation-based learning and its impact on their performance in Objective Structured Clinical Examination in Pediatrics - A mixed method study.

Objective: This study aims to assess the effectiveness of integrating simulation for teaching pediatric clinical examination skills to undergraduate, MBBS Year-IV medical students at The Aga Khan University, Karachi, Pakistan. Methods: In this mixed method study, the Objective Structured Clinical Examination (OSCE) scores of the students who were taught using simulation (batch 2017-2018) were compared with the batch of the academic year 2016 -2017 (taught via traditional methods). In order to explore the experiences of the intervention group, a questionnaire with four open-ended questions was administered at the end of the clerkship. Results: Students who were taught by simulation, scored significantly higher on the clinical skills stations in Objective Structured Clinical Examination, than in the pre-intervention group (p-value <0.01). The students quoted safety of the learning environment, opportunities for deliberate practice, debriefing and facilitation skills maximized quoted that their experience of learning through simulation, however, some challenges were identified for future improvement. Conclusion: The result of the study suggested simulation as a useful instructional strategy for teaching examination skills to students in their early years. The student gained confidence through deliberate practice and feedback without compromising patient safety, which translated into improved performance in the high-stakes OSCE examination at the end of the clerkship.

Frequency and Risk Factors of Permanent Hypoparathyroidism After Total Thyroidectomy: An Experience at a Tertiary Care Hospital in Pakistan.

OBJECTIVES: Thyroid surgeries are among the most common operations performed in the world. Hypocalcemia following total thyroidectomy (TT) is a common complication that is sometimes difficult to correct. This study aims to determine the frequency of hypocalcemia and permanent hypoparathyroidism (PtHPT) following TT. METHODS: A total of 363 patient records were reviewed who underwent TT for any reason. Thirty-eight patients did not have a follow-up in the clinic in the postoperative period and were excluded from the final analysis with the final sample as 325. For patients who developed hypocalcemia during the postoperative hospital stay, their lowest calcium levels were recorded and medical records were reviewed for the period of one year for the requirement of oral calcium and active form of vitamin D (calcitriol or alpha calcidiol) in the outpatient setting. Patients who required calcium and vitamin D supplementation for up to 1 year were labeled as having PtHPT. Risk factors were analyzed among those who developed PtHPT. RESULTS: From a total of 325 patients postoperative hypocalcemia developed in 163 (50.2%) patients, and 162 (49.8%) patients remained normocalcemic. Permanent hypoparathyroidism was found in 42(12.9%) patients and transient HPT in 121 (37.2%). Age, severe postoperative hypocalcemia (PoHC), and readmission for hypocalcemia were independent risk factors for PtHPT. CONCLUSIONS: Transient hypoparathyroidism (THPT) is common in our setup. Patients who develop severe hypocalcemia postoperatively and need readmission should be closely followed for the development of PtHPT.

Clinical and epidemiological features of pediatric population hospitalized with COVID-19: a multicenter longitudinal study (March 2020-December 2021) from Pakistan.

Background: We aimed to explore the epidemiological, clinical, and phenotypic parameters of pediatric patients hospitalized with COVID-19 in Pakistan. Methods: This longitudinal cohort study was conducted in five tertiary care hospitals in Pakistan from March 2020 to December 2021. Data on various epidemiological and clinical variables were collected using Case Report Forms (CRFs) adapted from the WHO COVID-19 clinical data platform at baseline and at monthly follow-ups for 3 months. Findings: A total of 1090 children were included. The median age was 5 years (Interquartile range 1-10), and the majority presented due to new signs/symptoms associated with COVID-19 (57.8%; n = 631), the most common being general and respiratory symptoms. Comorbidities were present in 417 (38.3%) children. Acute COVID-19 alone was found in 932 (85.5%) children, 81 (7.4%) had multisystem inflammatory syndrome (MIS-C), 77 (7.0%) had overlapping features of acute COVID-19 and MIS-C, and severe disease was found in 775/1086 (71.4%). Steroids were given to 351 (32.2%) patients while 77 (7.1%) children received intravenous immunoglobulins. Intensive care unit (ICU) care was required in 334 (31.6%) patients, and 203 (18.3%) deaths were reported during the study period. The largest spike in cases and mortality was from July to September 2021 when the Delta variant first emerged. During the first and second follow-ups, 37 and 10 children expired respectively, and medical care after discharge was required in 204 (25.4%), 94 (16.6%), and 70 (13.7%) children respectively during each monthly follow-up. Interpretation: Our study highlights that acute COVID-19 was the major phenotype associated with high severity and mortality in children in Pakistan in contrast to what has been observed globally. Funding: The study was supported by the World Health Organization (WHO), which was involved in the study design but played no role in its analysis, writeup, or publication.

Maternal and Paternal Attachment Patterns in Pakistani Internet Users During COVID-19.

With ever-growing Internet penetration and increasing numbers of social media applications, the apprehensions around problematic use of the Internet among young adults are rising. Among the determinants of problematic Internet use (PIU), parental attachment toward both fathers and mothers is considered significant. However, research in Pakistan, despite growing numbers of Internet users, is either insufficient or methodologically challenged. This study aims to address these gaps by using improved methodology to study PIU and parental attachment among young adults while also accounting for the impact of psychological distress due to COVID-19. Using a correlational quantitative research design, we recruited a total of 142 young adults (>18 years) residing in Pakistan, with no previous psychiatric history, who were asked to complete the Generalized Problematic Internet Use Scale-2, Experiences in Closed Relationships-Relationships Structures scale, and Kessler Psychological Distress Scale-10 (K10). Results showed that psychological distress had a significant positive association with PIU and paternal attachment had a significant positive association with PIU. Regression analysis showed that only duration of Internet use and psychological distress were significant predictors in the model and that parental attachment was nonsignificant. Furthermore, securely attached individuals reported significantly less psychological distress than those with fearful-avoidant and dismissive attachment styles. Therefore, our results show that general parental attachments are associated with psychological distress and psychological distress is associated with PIU. The implications of these findings are discussed.

Prevalence and risk factors of Severe Acute Respiratory Syndrome Coronavirus 2 infection in women and children in peri-urban communities in Pakistan: A prospective cohort study.

Background: Population-based seroepidemiological surveys provide accurate estimates of disease burden. We compare the COVID-19 prevalence estimates from two serial serological surveys and the associated risk factors among women and children in a peri-urban area of Karachi, Pakistan. Methods: The AMANHI-COVID-19 study enrolled women and children between November 2020 and March 2021. Blood samples were collected from March to June 2021 (baseline) and September to December 2021 (follow-up) to test for anti-SARS-CoV-2 antibodies using ROCHE Elecsys®. Participants were visited or called weekly during the study for recording symptoms of COVID-19. We report the proportion of participants with anti-SARS-CoV-2 antibodies and symptoms in each survey and describe infection risk factors using step-wise binomial regression analysis. Results: The adjusted seroprevalence among women was 45.3% (95% confidence interval (CI) = 42.6-47.9) and 82.3% (95% CI = 79.9-84.4) at baseline and follow-up survey, respectively. Among children, it was 18.4% (95% CI = 16.1-20.7) and 57.4% (95% CI = 54.3-60.3) at baseline and follow-up, respectively. Of the women who were previously seronegative, 404 (74.4%) tested positive at the follow-up survey, as did 365 (50.4%) previously seronegative children. There was a high proportion of asymptomatic infection. At baseline, being poorest and lacking access to safe drinking water lowered the risk of infection for both women (risk ratio (RR) = 0.8, 95% CI = 0.7-0.9 and RR = 1.2, 95% CI = 1.1-1.4, respectively) and children (RR = 0.7, 95% CI = 0.5-1.0 and RR = 1.4, 95% CI = 1.0-1.8, respectively). At the follow-up survey, the risk of infection was lower for underweight women and children (RR = 0.4, 95% CI = 0.3-0.7 and RR = 0.7, 95% CI = 0.5-0.8, respectively) and for women in the 30-39 years age group and children who were 24-36 months of age (RR = 0.6, 95% CI = 0.4-0.9 and RR = 0.7, 95% CI = 0.5-0.9, respectively). In both surveys, paternal employment was an important predictor of seropositivity among children (RR = 0.7, 95% CI = 0.6-0.9 and RR = 0.8, 95% CI = 0.7-1.0, respectively). Conclusion: There was a high rate of seroconversion among women and children. Infection was generally mild. Parental education plays an important role in protection of children from COVID-19.

Compassionate Healthcare for Parents of Children with Life-limiting Illnesses: A Qualitative Study.

Objectives: Premature death of a child from a serious illness is probably one of the most painful experiences for a parent. This study examined the clinical experiences of bereaved parents of children with a life-limiting illness to provide recommendations for quality care. Materials and Methods: Data were collected using semi-structured in-depth interviews with bereaved parents whose children had died at least 3 months before the interview. Parents were purposively sampled from two institutions offering end-of-life care to children with life-limiting illnesses. Data were analysed using thematic analysis. Results: Data analysis revealed three main themes: (1) Clinical communication, (2) Healthcare infrastructure and (3) Non-physical aspects of healthcare. The seven subthemes uncovered were as follows: (1) Honesty and clarity, (2) empathy, (3) interdisciplinary communication, (4) inconveniences in hospital, (5) home palliative care, (6) financial burden of illness and (7) psychosocial and spiritual support. Conclusion: Strategies to improve healthcare for children and their families are multifold. Underlying the provision of quality care is compassion; a child and family-friendly healthcare system with compassionate providers and compassionate institutional policies are vital components to achieving quality healthcare. Culturally sensitive psychosocial, emotional and spiritual support will need to be integrated as standard care.

Case Report: Urinary Tract Infection in a Diabetic Postmenopausal Woman With Multiple Episodes of Recurrence: An Antimicrobial Susceptibility dispute.

Urinary tract infection (UTI) is caused by bacteria growing in urine and affect kidneys, bladder, ureters, and urethra. Women with diabetes are at high risk of developing UTI. This is a case of a 60-year-old postmenopausal woman with uncontrolled type-I diabetes mellitus and hypertension, who presented with an acute onset of dysuria, burning micturition, and increased frequency. This case highlights the shortfall in the preliminary management plan of performing imperative clinical laboratory investigations including urine detailed report (DR), urine culture and sensitivity(C/S), and plasma glucose testing to initiate antimicrobial treatment. UTI requires to be treated precisely in diabetic patients with the help of a comprehensive diagnosis for signs of dysuria, frequent urination, and pelvic pain. The treatment of UTIs should always begin with culture and sensitivity analysis while the patient is symptomatic, to initiate antimicrobial treatment. Comorbidities should be managed appropriately during treatment to achieve desired therapeutic outcomes.

Pneumococcal Carriage in Infants Post-PCV10 Introduction in Pakistan: Results from Serial Cross-Sectional Surveys.

The 10-valent pneumococcal vaccine was introduced in Pakistan's Expanded Program on Immunization (EPI) in 2013 as a 3 + 0 schedule without catchup. We conducted three annual cross-sectional surveys from 2014−2016 to measure vaccine-type (VT) carriage in infants from a rural part of Pakistan. Nasopharyngeal specimens were collected by random sampling of infants from two union councils of Matiari. Samples were then transported to the Infectious Disease Research Laboratory (IDRL) at the Aga Khan University within 6−8 h of collection. Serotypes were established using sequential multiplex PCR. Of the 665 children enrolled across three surveys, 547 were culture-positive for pneumococcus. VT carriage decreased from 21.8% in 2014 to 12.7% in 2016 (p-value for trend <0.001). Those who were not vaccinated or partially vaccinated were found to be at higher risk of carrying a VT serotype ((aOR 2.53, 95% CI 1.39, 4.63 for non-vaccinated) and (aOR 3.35, 95% CI 1.82, 6.16 for partially vaccinated)). On the other hand, being enrolled in the most recent survey was negatively associated with VT carriage (aOR 0.51, 95% CI 0.28, 0.93). We found that PCV10 was effective in decreasing the carriage of vaccine-type serotypes in Pakistani infants.

Machine learning prediction of gestational age from metabolic screening markers resistant to ambient temperature transportation: Facilitating use of this technology in low resource settings of South Asia and East Africa.

Background: Knowledge of gestational age is critical for guiding preterm neonatal care. In the last decade, metabolic gestational dating approaches emerged in response to a global health need; because in most of the developing world, accurate antenatal gestational age estimates are not feasible. These methods initially developed in North America have now been externally validated in two studies in developing countries, however, require shipment of samples at sub-zero temperature. Methods: A subset of 330 pairs of heel prick dried blood spot samples were shipped on dry ice and in ambient temperature from field sites in Tanzania, Bangladesh and Pakistan to laboratory in Iowa (USA). We evaluated impact on recovery of analytes of shipment temperature, developed and evaluated models for predicting gestational age using a limited set of metabolic screening analytes after excluding 17 analytes that were impacted by shipment conditions of a total of 44 analytes. Results: With the machine learning model using all the analytes, samples shipped in dry ice yielded a Root Mean Square Error (RMSE) of 1.19 weeks compared to 1.58 weeks for samples shipped in ambient temperature. Out of the 44 screening analytes, recovery of 17 analytes was significantly different between the two shipment methods and these were excluded from further machine learning model development. The final model, restricted to stable analytes provided a RMSE of 1.24 (95% confidence interval (CI) = 1.10-1.37) weeks for samples shipped on dry ice and RMSE of 1.28 (95% CI = 1.15-1.39) for samples shipped at ambient temperature. Analysis for discriminating preterm births (gestational age <37 weeks), yielded an area under curve (AUC) of 0.76 (95% CI = 0.71-0.81) for samples shipped on dry ice and AUC of 0.73 (95% CI = 0.67-0.78) for samples shipped in ambient temperature. Conclusions: In this study, we demonstrate that machine learning algorithms developed using a sub-set of newborn screening analytes which are not sensitive to shipment at ambient temperature, can accurately provide estimates of gestational age comparable to those from published regression models from North America using all analytes. If validated in larger samples especially with more newborns <34 weeks, this technology could substantially facilitate implementation in LMICs.
