Immediate impacts of COVID-19 vaccination on glycemic control in type 1 diabetes mellitus: a systematic review and meta-analysis.

Objective: COVID-19 vaccination is recommended in diabetic patients since diabetes is associated with worse clinical outcomes in COVID-19 infection. The safety profile of different types of COVID-19 vaccines, especially on glycemic control, can be explored due to availability of data from continuous glucose monitoring (CGM) devices. This meta-analysis aimed to quantify the impact of COVID-19 vaccination on glycemic control in patients with type 1 diabetes mellitus (T1DM). Methods: A systematic search of PubMed, Embase, and Google Scholar was conducted using a search strategy for studies published till January 2023 in English language. Comparative observational studies reporting glycemic control obtained from CGM before and after COVID-19 vaccination in T1DM patients were included. The primary outcome was time in range (TIR) metric of proportion of glucose results falling within the range: 3.9-10 mmol/l. Other outcomes were time above range (TAR) (>10 mmol/l), time below range (TBR) (<3.9 mmol/l), coefficient of variation (CV), and mean blood glucose levels. The pooled outcomes were compared pre-vaccination and post-vaccination using Hedges' g (HG) with 95% CI. Results: A total of seven studies (632 participants) were included in the meta-analysis. COVID-19 vaccination caused small and statistically insignificant decrease in TIR after both the first (HG = 0.21, 95% CI: -0.02 to 0.44, P=0.07) and second dose (HG = 0.09, 95% CI: -0.04 to 0.21, P = 0.19). Likewise, TAR was not affected after neither first (HG = -0.09, 95% CI: -0.22 to 0.03, P = 0.12) nor second vaccine dose (HG = -0.07, 95% CI: -0.21 to 0.06, P = 0.30). Likewise, TBR, mean blood glucose levels, and CV were not significantly altered following uptake of either of the doses. Conclusion: COVID-19 vaccination has an excellent safety profile in T1DM patients owing to its minimal impacts on immediate glycemic control.

Chronic kidney disease on the background of bardet-biedl syndrome: a case report and review of literature.

Introduction: Bardet-Biedl syndrome (BBS) is a rare autosomal recessive multisystem disorder characterized by retinal dystrophy, obesity, postaxial polydactyly, renal dysfunction, learning difficulties, and hypogonadism. In this case report, the authors present the clinical course and management of a patient with BBS who developed chronic kidney disease (CKD). Case presentation: An 18-year-old male presented to the emergency department with chief complaints of fever, cough, vomiting, and decreased urine output for 7 days. Parents complained that the child had a delay in development compared to other children of the same age group. On examination, the patient had tachypnea, periorbital and pedal edema, expiratory wheeze with bilateral basal crackles, polydactyly, central obesity, microtestes, and delayed developmental milestones. Ultrasonography revealed bilateral small kidneys with increased cortical echotexture and loss of corticomedullary differentiation. Based on clinical features, the patient was diagnosed with CKD in the background of BBS. Hemodialysis was initiated after the diagnosis. Discussion: The management of CKD in the background of BBS poses unique challenges due to the complex multisystem involvement of this genetic disorder. There should be early reorganization and management of this condition so that the patient can have a better quality of life. Moreover, in developing countries like Nepal, genetic testing and diagnosis should be made easily accessible for better patient outcome. Conclusion: Multidisciplinary approach involving nephrologists, ophthalmologists, endocrinologists, and geneticists is important to optimize the treatment and long-term management of Badet Biedel patients.

Giant endometrial polyp in a post-menopausal woman: a rare case report from Nepal.

Introduction: Endometrial polyps (EPs) result from the overgrowth of endometrial glands and stroma. Giant endometrial polyps, defined as those exceeding 4 cm, are rare, and their association with phytoestrogen (PE) intake is infrequently reported. Case presentation: The authors present a case of a giant endometrial polyp in a 59-year-old post-menopausal woman from Nepal. The patient presented with lower abdominal pain and a history of vaginal spotting. She was not under any drugs or medications, including hormones, but had a regular intake of PE-rich foods. Imaging revealed a giant endometrial polyp and a uterine fibroid. Total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) were performed and histopathology examination confirmed the diagnosis of endometrial polyp and fibroid. Discussion: In our case, the patient's increased age and PE-rich diet were identified as potential risk factors for the giant endometrial polyp. Giant endometrial polyps are rare, with limited cases reported to date, often associated with tamoxifen or raloxifene use. Phytoestrogens can exhibit oestrogenic effects, contributing to endometrial polyps. This case emphasizes the importance of further research to explain the relationship between phytoestrogen intake and giant endometrial polyps. Conclusion: Giant endometrial polyps are uncommon, and their association with phytoestrogen intake remains underexplored. Clinicians should consider dietary factors in history while evaluating endometrial polyps, and further research is necessary to explore the potential role of phytoestrogens in the development of giant endometrial polyps.

Epidemiology, clinical characteristics, diagnosis, and complications of scrub typhus infection in Nepal: a systematic review.

Introduction: Scrub typhus (ST) is a neglected tropical disease of serious concern in Nepal. This systematic review aims to describe the burden of disease, clinical presentation, and complications of ST infection in Nepal. Methods: A systematic search of PubMed, EMBASE, Google Scholar, and national databases was conducted for any literature published in English between January 2000 and January 2023. Any type of study design (observational studies, case series, and interventional studies) that reported laboratory-confirmed ST and was conducted in Nepal among patients of all age groups was included. The seroprevalence of ST among acute undifferentiated febrile illness (AUFI) cases, geographical distribution, monthly distribution, clinical presentations, complications, and treatment were assessed by the study. Result: A total of 15 studies with 10, 977 participants were included in the review. The seroprevalence of ST among the AUFI cases in Nepal was 19.31%. Young people at or below 20 years of age were mostly affected. The maximum number of cases were reported from Bagmati province (59.46%) and in the month of August (26.33%). Fever, headache, cough, shortness of breath, nausea, and abdominal pain were the clinical characteristics in decreasing order of occurrence. The most common complication was acute kidney injury, followed by respiratory problems, cardiac issues, and neurological manifestations. The case fatality rate of ST in Nepal was 2.56%. Conclusion: The authors findings showed a significant burden of ST among AUFI cases in Nepal. Improved surveillance, general public awareness, and early detection post-calamities could help reduce the disease burden and improve patient outcomes.
