Filarial Abundant Larval Transcript Protein ALT-2: An Immunomodulatory Therapeutic Agent for Type 1 Diabetes.

Type 1 diabetes (T1D) that accounts for about 5-10 % of all diabetes cases results from the autoimmune destruction of the insulin-producing beta cells in the pancreas. It is characterized by severe inflammatory reaction mediated by pronounced T helper type-1 response. Parasitic infections having the ability to skew the host immune responses towards type-2 type as a part of their defense mechanism are able to induce protection against autoimmune diseases like T1D. Hence, the present study is undertaken to explore a recombinant abundant larval transcript protein of the human lymphatic filarial parasite Brugia malayi (rBmALT-2), a known anti-inflammatory molecule for its therapeutic effect on streptozotocin (STZ)-induced T1D in mice. The diabetic mice on treatment with rBmALT-2 showed a significant (p < 0.0005) decrease in their fasting blood glucose levels. By the end of the second week after the initiation of treatment with the rBmALT-2, 28 % of the diabetic mice became normal and none of them were diabetic by the end of 5th week. The anti-diabetic effect of rBmALT-2 significantly correlated with the concomitant redressal of the pancreatic histopathological damage caused by STZ assault (rho = 0.87; p < 0.0005). The sera of rBmALT-2 treated diabetic mice had increased levels of IgG1 antibodies associated with decreased IgG2a antibodies against the principal autoantigen insulin. The splenocyte proliferative response and the cytokine release in the treated mice showed marked bias against inflammation skewing the immune response to Th-2 type. From this study, it can be envisaged that that filarial proteins like rBmALT-2 with effective immunomodulatory activity and anti-diabetic effect are promising alternative therapeutic agents for T1D.

Chronic Alcoholism and Its Health Implications: A Case Report.

Individuals with chronic alcohol use can be asymptomatic for a prolonged period of time and then exhibit signs of advanced heart and liver diseases with an abrupt onset. Herein, we present a case of a 60-year-old male with severe alcohol use disorder who presented with newly diagnosed atrial fibrillation (AF) with rapid ventricular response (RVR), dilated cardiomyopathy (DCM), and alcohol-associated cirrhosis following an episode of binge drinking.

COVID-19 and ST elevations-keep an open mind: a case report.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has been associated with a range of cardiovascular manifestations, including myocardial injury and thrombo-embolism. Pulmonary embolism (PE) causing anteroseptal/anterior ST elevations that mimic myocardial infarction have previously been described. This phenomenon is thought to be related to right ventricular injury from large emboli. CASE SUMMARY: A 48-year-old woman with history of type 2 diabetes mellitus and hypertension presented to her local hospital with fever, cough, nausea, and dyspnoea. A test for SARS-CoV-2 was taken, and she was discharged with instructions to self-quarantine. She was subsequently notified of a positive SARS-CoV-2 result. Three days later, she re-presented with worsening dyspnoea and respiratory failure requiring intubation. On hospital Day 6, she became acutely hypoxic and hypotensive. Telemetry was noted to have ST changes, prompting ECG that revealed sinus tachycardia with prominent new ST elevations in her precordial leads. Transthoracic echocardiogram showed normal left ventricular function; however, the right ventricle was moderately dilated with positive McConnell's sign. Due to her unstable clinical state and high suspicion for PE, she was treated with tenecteplase 50 mg i.v. with complete resolution of her ST elevations and improved oxygenation. DISCUSSION: Given the high rates of thrombo-embolic events in COVID-19 patients, PE should be in the differential diagnosis of ST elevation, particularly in younger patients with few risk factors for coronary artery disease.

Principal component analysis approach for comprehensive screening of salt stress-tolerant tomato germplasm at the seedling stage.

Salt stress is a major abiotic factor that affects the growth and yield of crops. The present study was carried out to assess the salt tolerance among the Arka Samrat, Arka Rakshak, YVU-1, S-22, YVU-2, and PKM-OP tomato germplasms using principal component analysis (PCA). Different salt (NaCl) concentrations like control, 0.04 M, 0.12 M, and 0.20 M were selected in order to classify them into sensitive and tolerant tomato germplasms based on 13 parameters. A significant variation was observed among the selected tomato germplasms towards salinity tolerance at the seedling stage. Shoot length, root length, fresh weight, and dry weight parameters of the seedlings were decreased linearly with an increase in the external NaCl concentration. Salinization of plants has shown to reduce K+ content and increase in the Na+ accumulation, Ca2+, and Catalase activity. Salt stress also increased electrolyte leakage and reduced relative water content of all germplasms. The maximum parameters were less affected in Arka Rakshak and Arka Samrat compared to the remaining germplasms at higher salt stress. The PCA analysis of 13 morphological and physiological variables indicated that Arka Rakshak and Arka Samrat germplasms were salt-tolerant and PKM-OP was susceptible. Thus PCA analysis results are useful for the identification of resistance and sensitive germplasms at the seedling stage.

Impact of medial open-wedge high tibial osteotomy for medial compartment osteoarthritis of the knee.

BACKGROUND: Most populations worldwide, who are used to squatting and sitting cross-legged for their activities of daily living, largely comprise the lower socioeconomic strata, thus making them candidates for exclusion for total knee arthroplasty. Proximal/high tibial osteotomy (HTO) is a preferred strategy for clinically symptomatic osteoarthritis (OA) with genu varum due to painful medial compartment OA which is not amenable to conservative measures. AIM: To evaluate the outcomes of medial open-wedge HTO along with autologous bone grafting and buttress plate for the treatment of genu varum due to OA of the knee in a rural population of central India. METHODS: A total of 65 knees in 56 patients with a mean age of 58.22 ± 5.63 years with genu varum due to intractable painful knee OA were treated with medial open-wedge HTO along with autologous bone grafting and buttress plate osteosynthesis from June 2015 to May 2018. The mean preoperative radiological angle of genu varum was 13.4°. Clinical outcomes were assessed by the range of movement, knee scores, pain scores, and functional scores. Radiographic studies were performed preoperatively and at regular intervals during the follow-up period. RESULTS: All patients reported pain relief immediately after the osteotomy and during the long-term analysis covering between one to three years. The genu varum angle was overcorrected to approximately four degrees in all patients. There was a loss of reduction by approximately three degrees in all patients at around six weeks postoperatively. Preoperative knee movements were restored in all patients. No major perioperative complications were noted during surgery and postoperative follow-up and the clinical scores were significantly improved during the final analysis which revealed good pain relief. CONCLUSION: Medial open-wedge HTO is a reliable, safe, practical, physiological, and feasible treatment for populations who are used to increased activity in their occupation and lifestyle and is associated with excellent short-term and long-term results for OA in genu varum knees.
