Clinical characteristics, management, outcome, and cost of stings and bites in patients admitted to a tertiary care teaching hospital.

AIM: The objective of this study was to identify the clinical epidemiology and medical cost of stings and bites at a tertiary care hospital in South India. SUBJECTS AND METHODS: The medical records of hospitalized patients in the tertiary care unit between 2016 and 2020 with the history of either being stung or bitten by insects were reviewed retrospectively. The patient's demographic details, clinical symptoms, treatment chart, expenditure details, and outcomes were collected in pre-structured case report forms. The data were analyzed using SPSS Version 20.0. RESULTS: A total of 66 patients were enrolled, with a mean age of 45.86 ± 23.37 years. The majority of the incidence was due to bee stings (61%). Anaphylaxis was reported in 38% of the cases, followed by acute kidney injury (10.6%). The cost of hospitalization was found to be higher for spider bites at 896.73 ± 1414.95 USD, followed by wasp stings at 989.81 ± 1185.57 USD. In patients with complications, the average cost of stings and bites was 438.81 ± 685.81 USD. Most of the patients received antibiotics (75.8%), followed by steroids (62.1%). CONCLUSION: Stings and bite injuries may appear harmless initially, but they can cause severe complications in unidentified cases and for those who do not seek urgent medical attention. Antibiotics and corticosteroids can help in the management of envenomation.

Analysis of time-domain indices, frequency domain measures of heart rate variability derived from ECG waveform and pulse-wave-related HRV among overweight individuals: an observational study.

Background: Research on the compatibility of time domain indices, frequency domain measurements of heart rate variability obtained from electrocardiogram (ECG) waveforms, and pulse wave signal (pulse rate variability; PRV) features is ongoing. The promising marker of cardiac autonomic function is heart rate variability. Recent research has looked at various other physiological markers, leading to the emergence of pulse rate variability. The pulse wave signal can be studied for variations to understand better changes in arterial stiffness and compliance, which are key indicators of cardiovascular health. Methods: 35 healthy overweight people were included. The Lead II electrocardiogram (ECG) signal was transmitted through an analog-to-digital converter (PowerLab 8/35 software, AD Instruments Pty. Ltd., New South Wales, Australia). This signal was utilized to compute Heart Rate Variability (HRV) and was sampled at a rate of 1024 Hz. The same AD equipment was also used to capture a pulse signal simultaneously. The right index finger was used as the recording site for the pulse signal using photoplethysmography (PPG) technology. Results: The participants' demographic data show that the mean age was 23.14 + 5.27 years, the mean weight was 73.68 +  7.40 kg, the mean body fat percentage was 32.23   +  5.30, and the mean visceral fat percentage was 4.60   +  2.0. The findings revealed no noticeable difference between the median values of heart rate variability (HRV) and PRV. Additionally, a strong correlation was observed between HRV and PRV. However, poor agreement was observed in the measurement of PRV and HRV. Conclusion: All indices of HRV showed a greater correlation with PRV. However, the level of agreement between HRV and PRV measurement was poor. Hence, HRV cannot be replaced with PRV and vice-versa.

Factors contributing to the adverse drug reactions associated with the dipeptidyl peptidase-4 (DPP-4) inhibitors: A scoping review.

BACKGROUND AND AIM: Adverse drug reactions are one of the contributors to increased hospital admission and length of hospital stay. Among the various antidiabetic agents prescribed, dipeptidyl peptidase-4 (DPP-4) inhibitors have gained wide recognition and shown more persistence than other novel hypoglycemic agents. We performed a scoping review to identify the risk factors contributing to the adverse drug reactions with DPP-4 inhibitors. METHODOLOGY: We followed Preferred Reporting Items for Scoping Review (PRISMA-ScR) Guidelines for reporting the findings. Data sources such as PubMed/MEDLINE, Scopus, Embase, and Cochrane were assessed. We included studies that reported the risk factors contributing to the DPP-4 inhibitor-associated adverse drug reactions. The Joanna Briggs Institute (JBI) critical appraisal checklist was used to assess the methodological quality of the studies. RESULTS: Of the 6406 studies retrieved, 11 studies met our inclusion criteria. Of these 11 studies, seven were post-marketing surveillance studies, one nested case-control study, one comparator cohort study, one food and drug administration (FDA) adverse event reporting system (FAERS)-based observational study, and one questionnaire-based cross-sectional survey study. A total of eight factors were identified that contributed to the DPP-4 inhibitor-associated adverse drug reactions. CONCLUSION: The included studies suggested age >65 years, females, grade 4 and 5 renal impairment, concomitant drugs, disease and drug therapy duration, liver disease, non-smokers, and non-hypertension as risk factors. Further studies should be conducted to provide insight into these risk factors so that the appropriate use of DPP-4 inhibitors in the diabetic population can be encouraged to improve the health-related quality of life.

Effect of physical activity promotion on adiponectin, leptin and other inflammatory markers in prediabetes: a systematic review and meta-analysis of randomized controlled trials.

AIMS: Inflammatory stage in prediabetes is associated with increase in level of adipokines and pro-inflammatory cytokines. Physical activity promotion considered as a first-line therapeutic strategy to treat prediabetes. We have conducted the systematic review and meta-analysis to strengthen the evidence on the impact of physical activity promotion on inflammatory markers in prediabetes. METHODS: Studies were identified using electronic search and manual search techniques by choosing keywords for prediabetes, physical activity and inflammatory marker. Randomized controlled trials on individuals diagnosed with prediabetes and provided intervention in the form of physical activity were included in this review. Adiponectin, leptin, C-reactive protein, interleukin-6 and tumour necrosis factor-α were the considered outcome measures. RESULTS: Our search retrieved 1,688 citations, 31 full-text articles assessed for eligibility of inclusion. Nine studies satisfied the pre-specified criteria for inclusion. Meta-analysis found that physical activity with or without dietary or lifestyle modification reduces level of leptin (MD-2.11 ng/mL, 95% CI -3.81 - -0.42) and interleukin-6 (MD -0.15 pg/mL, 95% CI -0.25--0.04). It has no effect on level of adiponectin (MD 0.26 µg/mL, 95% CI -0.42- 0.93), C-reactive protein (MD -0.05 mg/L, 95% CI -0.33-0.23) and tumour necrosis factor-α (MD 0.67 pg/mL, 95% CI -2.56-3.89). CONCLUSIONS: This review suggests that physical activity promotion with dietary and lifestyle modification may reduce the level of leptin and interleukin-6 but are uncertain if there is any effect on levels of adiponectin, C-reactive protein and tumour necrosis factor-α in the individuals with prediabetes.

Prevalence of Foot Complications in People With Type 2 Diabetes Mellitus: A Community-Based Survey in Rural Udupi.

The objective of the study was to determine the prevalence of foot complications among people with type 2 diabetes mellitus in the rural part of Udupi district, Karnataka, India. A cross-sectional observational study design was conducted in the rural area of Udupi district. In the study, accredited social health activists were trained to screen people with type 2 diabetes mellitus for diabetic foot complications at a community level. Adults over 35 years of age were screened for the presence of type 2 diabetes mellitus by accredited social health activists who reside in the rural part of Udupi district. Participants with type 2 diabetes mellitus were included in the study. Blood glucose level was measured using a glucometer. Foot examination was done by visual inspection, monofilament, tuning fork, and pedal pulse. In the present study, 2110 among the total participants were found to have type 2 diabetes mellitus. The prevalence of musculoskeletal foot complications was 1218 (58%), vascular problem 466 (22.2%), sensory neuropathy 634 (30.2%), autonomic neuropathy 1729 (81.9%), ulcer 134 (6.38%), and infection 561 (26.7%) among people with type 2 diabetes mellitus. In the current study, we found 84.7% of people residing in rural Udupi had type 2 diabetes mellitus. Hence, there is a strong need to create awareness about diabetic foot care in these people.

Carbamazepine Induced Thrombocytopenia.

Antiepileptic Drugs (AEDs) are commonly associated with haematological disorders, including anaemia, thrombocytopenia, neutropenia and even bone marrow failure. Fatal disorders like aplastic anaemia are uncommon. On exploring through the literature, older AEDs are more associated with haematological alterations than newer AEDs, and careful monitoring is warranted especially with phenytoin, carbamazepine and valproate. The exact cause of these alterations is not established, though immune mechanisms and pharmacology of individual drugs are the proposed mechanisms, a further research along this path is underway. Of worth mentioning here, this predilection of older AEDs towards haematological disorders is pronounced in children compared to adults. We present here a case of congenital heart disease with history of brain abscess and seizures, on carbamazepine who presented to our hospital with toothache. Routine screening prior to tooth extraction revealed thrombocytopenia. Further evaluation revealed the association of carbamazepine and thrombocytopenia, which mandated discontinuation of drug and switching patient to alternative AED.
