Evaluation of the Efficacy and Safety of Intravenous Immunoglobulin (IVIG) in Moderate-to-Severe Hospitalized COVID-19 Patients: A Randomized, Open-Label Parallel-Group Study.

Purpose: Since February 2020, the world has been overwhelmed by the SARS-CoV-2 outbreak, and several patients suffered interstitial pneumonia and respiratory failure requiring mechanical ventilation, threatening the capability of healthcare systems to handle this amount of critical cases. Intravenous immunoglobulins (IVIG) possess potential immunomodulatory properties beneficial for COVID-19 patients, yet evidence supporting IVIG as adjunctive therapy remains sparse. This study evaluated the outcomes of adjunctive IVIG with the standard of care (SoC) in moderate-to-severe COVID-19 patients. Methods: This randomized study included 59 moderate-to-severe COVID-19 patients with known comorbidities. One arm (n = 33) received high-dose IVIG (400 mg/kg/day) within 48 hours for five days alongside SoC, while the other arm (n = 26) received SoC, comprising steroids, enoxaparin, and remdesivir. The primary endpoint was clinical improvement, as measured by the National Early Warning Score 2 (NEWS2) and discharged/death proportions. Secondary outcomes included IVIG safety, hospitalization duration, changes in oxygen saturation, inflammatory markers, IgG titer, CTSS (CT severity score), and radiological findings. Results: There was an improvement in the NEWS2 at the end of treatment in the IVIG arm (5.67 vs. 5.96). A significant absolute effect improvement (Day 1 vs. Day 9) was seen in serum LDH, D-dimer, hs-CRP, IL-6, CTSS, procalcitonin, respiratory rate, and chest radiographic findings. SARS-CoV-2 IgG titer increased significantly in the IVIG arm. There was a statistically significant reduction in mortality in the IVIG group (5 vs. 10). Conclusion: IVIG was a safe and effective adjunctive therapy to SoC treatment in moderate-to-severe COVID-19 patients needing ventilatory support. Furthermore, studies are required to validate our findings. This trial is registered with CTRI/2021/05/033622.

Hypertension care cascade in an urban resettlement colony and slum in Delhi, India: a cross-sectional survey.

BACKGROUND: Hypertension care cascade in resource-limited settings is compromised with a majority of patients with hypertension remaining undiagnosed, untreated, non-adherent, and poorly controlled at every stage. However, there is paucity of information on care and management of hypertensive patients in community-based settings of low-income urban neighbourhoods in India. METHODS: This was a community-based cross-sectional study conducted in an urban resettlement colony and slum area in the Northeast District of Delhi. The adult population was screened for hypertension using standardized methods, and adherence to medications was assessed using the Morisky Green Levine scale. Binary logistic regression analysis was conducted to ascertain the sociodemographic predictors of the outcome (presence of hypertension, adherence to antihypertensive medication, blood pressure control). A p-value < 0.05 was considered statistically significant. RESULTS: We included 8850 adult participants including 5295 females and 3555 males in this study. Nearly 29% of the participants were hypertensive, of which 61.77% were newly diagnosed cases. Furthermore, nearly 81% of the previously diagnosed cases had been initiated on antihypertensive medication, of which 57.54% were adherent to their medications while 36.12% attained controlled blood pressure levels. The odds of having hypertension were significantly higher among males (AOR = 1.87, 95% CI: 1.63 to 2.15), age ≥ 60 years (AOR = 9.15, 95% CI: 7.82 to 10.70), high waist circumference (AOR = 2.24, 95% CI: 1.86 to 2.70) and Body Mass Index of ≥ 25.00 (AOR = 2.55, 95% CI: 2.00 to 3.26). Furthermore, on adjusted analysis, patients of hypertension having diabetes (DM) comorbidity had significantly higher odds of being adherent to anti-hypertensive medications (AOR = 1.81, 95% CI: 1.31 to 2.51) compared to those without DM comorbidity, while tobacco users had significantly lower odds of being adherent to antihypertensive medication (AOR = 0.50, 95% CI: 0.31 to 0.82). CONCLUSIONS: Hypertension care cascade in urban slum-resettlement colony setting revealed a high burden of undiagnosed hypertension, low rates of medication adherence, and poor blood pressure control. Strengthening community screening and primary care continuum of care is necessary to improve the hypertension care cascade from early diagnosis to effective management with optimal health outcomes to reduce patient complications and increase longevity.

Comparison of Serum Holotranscobalamin with Serum Vitamin B12 in Population Prone to Megaloblastic Anemia and their Correlation with Nerve Conduction Study.

Early detection of megaloblastic anemia and associated neurological complications is crucial for management. This study was conducted to compare serum holotranscobalamin level with serum vitamin B12 level as early biomarker in people prone to megaloblastic anemia and to evaluate co-relation between these biomarkers and nerve conduction study in study patients. 83 adult patients (Hb > 12 gm/dl) prone to megaloblastic anemia were studied for basic haematological investigations, random blood sugar, thyroid function test, liver function test, kidney function test, serum vitamin B12, serum holotranscobalamin and serum folic acid levels. 45 patients among them underwent nerve conduction studies. All study patients were classified in 6 groups on the basis of risk factors for megaloblastic anemia. 29 patients (34.9%) were on antiepileptic drugs, 26 (31.3%) were chronic alcoholic, 10 patients (12%) each, had malabsorption and ileal tuberculosis, 6 (7.22%) had chronic pancreatitis and 2 (2.4%) had ileal resection. 30 patients (36.14%) had low serum holotranscobalamin, including 7 patients (8.43%) with low serum vitamin B12 level also, unmasking vitamin B12 deficiency in 23 patients (27.7%). 7 patients (8.43%) had mean corpuscular volume (MCV) > 100fL and 8 patients (9.63%) had vitamin B12 deficiency related changes on peripheral smear. Serum vitamin B12 and holotranscobalamin levels were significantly low in patients with peripheral smear changes, with p value 0.039 and 0.041 respectively, while no such association seen with MCV. Subclinical peripheral neuropathy was detected in 18 (40%) out of 45 patients on nerve conduction study. Serum holotranscobalamin levels were significantly lower (p = 0.031) than serum vitamin B12 levels (p = 0.2) in patients with neuropathic changes. Rest investigations and serum folic acid levels were normal in all patients. Holotranscobalamin levels can be considered early and reliable marker for vitamin B12 deficiency and deficiency associated peripheral neuropathy, even in patients who are prone to megaloblastic anemia, and not yet anemic or symptomatic for neuropathy.

COVID associated mucormycosis: A preliminary study from a dedicated COVID Hospital in Delhi.

BACKGROUND: It is an incontrovertible fact that the Rhino Orbital Cerebral Mucormycosis (ROCM) upsurge is being seen in the context of COVID-19 in India. Briefly presented is evidence that in patients with uncontrolled diabetes, a dysfunctional immune system due to SARS-COV-2 and injudicious use of corticosteroids may be largely responsible for this malady. OBJECTIVE: To find the possible impact of COVID 19 infection and various co-morbidities on occurrence of ROCM and demonstrate the outcome based on medical and surgical interventions. METHODOLOGY: Prospective longitudinal study included patients diagnosed with acute invasive fungal rhinosinusitis after a recent COVID-19 infection. Diagnostic nasal endoscopy (DNE) was performed on each patient and swabs were taken and sent for fungal KOH staining and microscopy. Medical management included Injection Liposomal Amphotericin B, Posaconazole and Voriconazole. Surgical treatment was restricted to patients with RT PCR negative results for COVID-19. Endoscopic, open, and combined approaches were utilized to eradicate infection. Follow-up for survived patients was maintained regularly for the first postoperative month. RESULTS: Out of total 131 patients, 111 patients had prior history of SARS COVID 19 infection, confirmed with a positive RT-PCR report and the rest 20 patients had no such history. Steroids were received as a part of treatment in 67 patients infected with COVID 19. Among 131 patients, 124 recovered, 1 worsened and 6 died. Out of 101 known diabetics, 98 recovered and 3 had fatal outcomes. 7 patients with previous history of COVID infection did not have any evidence of Diabetes mellitus, steroid intake or any other comorbidity. CONCLUSION: It can be concluded that ROCM upsurge seen in the context of COVID-19 in India was mainly seen in patients with uncontrolled diabetes, a dysfunctional immune system due to SARS-COV-2 infection and injudicious use of corticosteroids.

Evaluation of the plantar fascia in patients with diabetes mellitus: the role of sonoelastography.

Purpose: It has been postulated that hyperglycaemic non-enzymatic glycation of proteins with subsequent accumulation of glycosylated end-products in tissues like the plantar fascia (PF) contributes to the development of foot ulcers in diabetics. The present study evaluates the spectrum of sonoelastographic findings in the plantar fascia in patients with type 2 diabetes mellitus (DM). Material and methods: A total of 81 patients and 32 healthy volunteers were included in the study. PF thickness was registered 1 cm distal to the attachment at the calcaneus. Greyscale ultrasonographic examination was followed by strain elastography of the PF based on which PF were qualitatively categorized into 3 grades (hard, intermediate, soft) depending on their predominant colour. Results: Patients were found to have thicker PF than healthy volunteers (p < 0.0001). Grade 2 (intermediate elasticity) PF was the most common type seen in both groups (48.44% of healthy volunteers and 57.25% of patients). However, a greater number of patients (36.64%) had grade 3, i.e. soft PF as compared to healthy volunteers (9.38%). Conclusions: To conclude, there is thickening and softening of the PF in patients with type 2 DM, supporting the hypo-thesis that diabetes-induced changes occur in the tissues of the foot.

Outcomes among 10,314 hospitalized COVID-19 patients at a tertiary care government hospital in Delhi, India.

A significant proportion of patients with coronavirus disease 2019 (COVID-19) require timely hospitalization to reduce the risk of complications and mortality. We describe the trends of the age and gender stratified outcomes among hospitalized COVID-19 patients with moderate to severe illness at the largest dedicated tertiary care COVID-19 government hospital in New Delhi, India. A retrospective cohort study through secondary data analysis from in-patient hospital data of patients admitted from April 1 to November 15, 2020 was conducted. The data of 10,314 laboratory-confirmed patients with COVID-19 was analyzed, of which 8899 (86.28%) were discharged after recovery, and 1415 (13.72%) died. The mean (SD) age of the hospitalized patients was 46.43 (18.74) years (n = 10,309) including 6031 (58.50%) male and 4278 (41.50%) female patients (n = 10,309). On bivariate analysis, increasing age was associated with significantly higher odds of mortality in both gender (p < .001). The mortality rate in female patients was lower (11.92%) compared with male patients (15.75%) (p = .675). However, elderly women had the highest odds of mortality (p < .001), indicating the possible role of delayed health seeking behavior, secondary to familial, and social neglect. Mortality in the patients with COVID-19 also occurred early after admission suggesting rapid deterioration, delayed reporting by patients, or their late referral from other health facilities. However, the overall statewide recovery rate showed steady improvement since the onset of the pandemic. In contrast, the recovery rate among the moderate-severe cases that were hospitalized at this tertiary care center during the same period reflected a lower nonspecific zigzag pattern indicating limited effectiveness of the COVID-19 treatment regimens.

Text messaging improves diabetes-related knowledge of patients in India: A quasi-experimental study.

Background: . Diabetes-related health education promotes patient efficacy for diabetes self-management. However, sub-optimal knowledge of diabetes in people with diabetes is recognized as a challenge in overcrowded public health facilities in India. We aimed to determine the effect of health education through mobile phone text messages (short messaging service [SMS]) on diabetes-related knowledge of patients with diabetes. Methods: . From February 2016 to February 2017, we recruited adult patients with diabetes for this quasi-experimental study done in the outpatient setting of a major tertiary care government hospital in Delhi, India. Participants in the intervention group received a text message on diabetes self-care practices every alternate day for 90 days. We evaluated the patients' knowledge of diabetes using the Spoken Knowledge in Low Literacy in Diabetes (SKILL-D) questionnaire and a self-designed diabetes knowledge questionnaire. Results: . We enrolled 190 men and 160 women, of whom 52 (13.7%) were lost to follow-up. At baseline, mean diabetes knowledge scores were higher in the intervention group compared to the control group. After the intervention period of 3 months, the diabetes knowledge scores for SKILL-D and the patient diabetes knowledge questionnaire showed a statistically significant increase in the intervention group (mean difference 0.7 and 0.5, respectively; p<0.001, but there was no increase in the control group). Conclusion: . The use of mobile phone technology for diabetes-related health education through mobile text-message (SMS) technology is an effective method for health promotion.

Characterization of midgut microbiome of Anopheles stephensi Liston.

BACKGROUND & OBJECTIVES: Anopheles stephensi is an important vector of malaria in South East Asia. The abundance and diversity of gut microbiota in the disease vectors affect their development, digestion, metabolism and immunity. The immatures of An. stephensi engulf microbes from their aquatic environment. The present study investigates midgut microbiota of wild and laboratory populations and compares it with their habitat bacterial diversity to study transstadial transmissibility. METHODS: The gut microbes from immatures, adults and water samples were cultured at ambient conditions on different media. The colony and biochemical characteristics, and 16S rRNA gene sequencing of gut microbes were studied. RESULTS: Altogether, 298 bacterial isolates were characterized as 21 genera belonging to four major Phyla viz., Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria. In the field population-1, Proteobacteria and Firmicutes accounted for 49% and Actinobacteria constituted 51% of the bacterial isolates. In field population-2, Bacteroidetes and Firmicutes accounted for 99% of the isolates. In the laboratory populations, Firmicutes constituted 77%, while Proteobacteria 23% of the isolates. Additionally, 9 genera occurred in the breeding habitats, 13 in the larval midgut, 6 in pupal midgut, 9 in male midgut and 10 in the female midgut. INTERPRETATION & CONCLUSION: This is a unique study on diversity of microbiota of An. stephensi from breeding water, developmental stages and adults. Different culture media used enhanced the isolation of diverse bacteria. The presence of Micrococcus and Leucobacter in different life stages indicates their adaptation in An. stephensi as symbionts which need further evaluation for their role in paratransgenesis.

Expert Consensus Statements on the Use of Corticosteroids in Non-severe COVID-19.

INTRODUCTION: There is strong evidence for the use of corticosteroid in the management of severe coronavirus disease-2019 (COVID-19). However, there is still uncertainty about the timing of corticosteroids. We undertook a modified Delphi study to develop expert consensus statements on the early identification of a subset of patients from non-severe COVID-19 who may benefit from using corticosteroids. METHODS: A modified Delphi was conducted with two anonymous surveys between April 30, 2021, and May 3, 2021. An expert panel of 35 experts was selected and invited to participate through e-mail. The consensus was defined as >70% votes in multiple-choice questions (MCQ) on Likert-scale type statements, while strong consensus as >90% votes in MCQ or >50% votes for "very important" on Likert-scale questions in the final round. RESULTS: Twenty experts completed two rounds of the survey. There was strong consensus for the increased work of breathing (95%), a positive six-minute walk test (90%), thorax computed tomography severity score of >14/25 (85%), new-onset organ dysfunction (using clinical or biochemical criteria) (80%), and C-reactive protein >5 times the upper limit of normal (70%) as the criteria for patients' selection. The experts recommended using oral or intravenous (IV) low-dose corticosteroids (the equivalent of 6 mg/day dexamethasone) for 5-10 days and monitoring of oxygen saturation, body temperature, clinical scoring system, blood sugar, and inflammatory markers for any "red-flag" signs. CONCLUSION: The experts recommended against indiscriminate use of corticosteroids in mild to moderate COVID-19 without the signs of clinical worsening. Oral or IV low-dose corticosteroids (the equivalent of 6 mg/day dexamethasone) for 5-10 days are recommended for patients with features of disease progression based on clinical, biochemical, or radiological criteria after 5 days from symptom onset under close monitoring.

High resolution ultrasonography of peripheral nerves in diabetic peripheral neuropathy.

PURPOSE: The purpose of the study was to assess the usefulness of high-resolution ultrasonography (HRU) in the evaluation of diabetic peripheral neuropathy (DPN). METHODS: Thirty-seven adult diabetic patients with clinically diagnosed DPN and 45 healthy adult volunteers were included in the study. HRU of the right medial, ulnar, common peroneal, and posterior tibial nerves was done. The mean cross-sectional area (CSA) of the involved nerves was measured in the two groups at identical positions. The CSA was compared between the two groups, and Student t-test was applied to assess statistical significance. RESULTS: There was a significant increase in the CSA of the median, ulnar, common peroneal, and posterior tibial nerve in DPN patients as compared to healthy volunteers. Sonographic findings were compared with nerve conduction study (NCS) for all the nerves studied except common peroneal nerve (CPN), as the NCS of CPN is not routinely done. DPN was classified as mild or moderate to severe on the basis of latency and velocity assessed by NCS. The mean CSA in all the examined nerves was higher in moderate to severe DPN than the mild DPN, but this was not statistically significant except for ulnar nerve with a P value of < 0.0001. CONCLUSION: HRU demonstrates a morphological change in patients with DPN in the form of an increase in CSAs, which was statistically significant. HRU can objectively complement other diagnostic investigations such as NCS. High resolution ultrasonography of peripheral nerves has the potential to become the investigation of first choice for the evaluation of DPN.

Efficacy and Safety of Levocloperastine in the Treatment of Dry Cough: A Prospective Observational Study.

Purpose/Aim: To evaluate effectiveness and safety of Levocloperastine in the treatment of dry cough in adult Indian patients. Methods: In this prospective, observational study, patients aged 18-60 years, presenting with dry cough and prescribed with Levocloperastine at baseline or a day prior to enrolment, as per standard clinical practice, were recruited from 3 centers in India. The scores of cough severity (100 mm VAS), cough frequency since last 24 h (7-point Likert scale), sleep disruption due to night-time awakenings (10 cm VAS), quality of life (QoL) (Leicester Cough Questionnaire [LCQ]), and number of days for achieving minimal important difference (MID) in cough severity (17 mm improvement on VAS) were assessed from baseline to Day 14. In addition, physicians' assessment of effectiveness of Levocloperastine at Day 14, adverse drug reactions (ADRs) and proportion of patients reporting sedation and other central nervous system side effects were also reported during the study. Descriptive statistics was used to summarize the data. Results: A total of 100 patients were enrolled in the study. The mean scores of cough severity, cough frequency and sleep disruption due to night-time awakening were significantly reduced from baseline to Day 14 (p<0.0001). A significant improvement in QoL scores (total and by domain) was noted from baseline to Day 14 (p<0.0001). Post treatment with Levocloperastine, the mean time for achieving MID was 5.3±0.26 days. Disappearance of cough was reported in 44% of patients; 54% patients reported improvement of cough by Day 14. No ADRs, cases of sedation or other side-effects were reported in the study. Conclusion: Levocloperastine was found to be effective and safe in the management of dry cough. A significant reduction in severity scores, frequency of cough and sleep disruption was reported, with an overall improvement in patient's QoL.

Comparative prospective study between medial and lateral distal tibial locking compression plates for distal third tibial fractures.

PURPOSE: Tibial fracture is the most common long bone fracture. Distal third tibial fractures are challenging though open reduction and plating can result in anatomical reduction and rigid fixation. This paper aimed to evaluate and compare the results of medial and lateral locking compression plates for distal third tibial fractures. METHODS: This prospective clinical study involved 36 patients with distal tibial fractures admitted in Department of Orthopaedics, Sawai Mansingh Medical College & Affiliated Hospital, Jaipur, India, from June 2011 to May 2012, including 29 closed fractures and 7 open fractures at the mean age of 38.9 years. Thirty-six patients were divided equally into two groups based on treatment method, including medial plating group (18 patients) and lateral plating group (18 patients). They were followed up for at least 5 months after discharge. The functional outcomes were evaluated using Tenny and Wiss clinical assessment criteria. RESULTS: Malunion was found in 3 cases of medial plating group and in 1 case of lateral plating group. In the medial plating group, there were 5 cases of superficial infections, 1 deep infection, 1 nonunion and 3 wound dehiscence. In the lateral plating group, there was 1 case of superficial infections, 1 deep infection and 1 nonunion. In the lateral plating group, 4 patients reported feeling the plates and screws but none of them asked to remove the hardware. In the medial plating group, 9 patients reported symptomatic hardware problems and 7 asked to remove the hardware. The number of cases graded as excellent/good/fair was 1/8/7 in the medial plating group and 3/7/7 in the lateral plating group respectively. In the medial plating group, the final range of motion was 17.2° in ankle dorsiflexion and 30.7° in ankle plantar flexion. In the lateral plating group, the final range of motion was 19° in ankle dorsiflexion and 34.2° in ankle plantar flexion. CONCLUSION: Lateral plating of distal tibia is safe and feasible, which can provide biological fixation and prevent the soft tissue complications associated with medial plating.

Infection control knowledge and practice: A cross-sectional survey on dental laboratories in dental institutes of North India.

AIM AND OBJECTIVES: The aim of the study was to assess the knowledge of dental laboratory technicians regarding infection control and modes of infection control employed by them. SETTINGS AND DESIGN: A self-assessment questionnaire-based survey was carried out among dental technicians to assess the knowledge and practice of infection control in dental laboratories. MATERIALS AND METHODS: Survey instrument containing 16 questions were randomly distributed to 70 dental colleges of North India regarding knowledge of infection control methods and infection control practised in laboratories. Data were collected and analyzed. RESULTS: The response showed that 30.76% of dental technicians receive 30-50 or more than 50 impressions in a week. About 96.15% of the technicians used a plastic bag to carry impressions. Twenty-five percent of the dental technicians were aware of infection control protocol. Fifty-five percent of the technicians received impressions while wearing gloves and 61.53% of the institutes had a separate receiving area. Nearly 71.15% of the technicians communicate with the doctor regarding the disinfection of impression received in the laboratory. Almost 30.76% of the dental technicians disinfect all the impressions and 67.30% technicians use immersion for disinfection of impressions. Only 38.46% responded that they immerse impressions for 10 min for disinfection. About 73.07% use gloves, 90.38% use mouth masks, 57.69% wear eye shields, and 88.46% wear aprons while working. Nearly 78.84% of the technicians received vaccination against hepatitis B virus. Almost 69.23% of the technicians change pumice slurry after regular intervals, and 75% do not add any disinfectant. Nearly 59.61% of technicians disinfect the prostheses before sending it to the clinic, and 42.30% disinfect them by immersion technique. About disposal of waste, 80.76% said that they dispose the waste properly. CONCLUSION: To summarize, most of the technicians were not aware of basic infection control protocols.

Design, synthesis and biological evaluation of functionalized phthalimides: a new class of antimalarials and inhibitors of falcipain-2, a major hemoglobinase of malaria parasite.

Phthalimides functionalized with cyclic amines were synthesized, characterized and screened for their in vitro antimalarial efficacy against Plasmodium falciparum (Pf3D7). Of all the listed phthalimides evaluated, 14 and 24 were identified as potent antimalarial agents as advocated by assessment of their ability to inhibit [(3)H] hypoxanthine incorporation in the nucleic acid of parasites. In addition, phthalimides 14 and 24 were incubated for 60 and 90h and an enhanced antimalarial effect was noticed with increase in time to great extent. A reduction in IC50 values was observed with increase in exposure time of the parasite to the compounds. A symmetric phthalimide, 24 possessing piperazine as linker unit was identified as the most potent antimalarial agent with IC50 values of 5.97±0.78, 2.0±1.09 and 1.1±0.75µM on incubation period of 42, 60 and 90h, respectively. The abnormal morphologies such as delay in developmental stages, growth arrest and condensed nuclei of parasite were observed with the aid of microscopic studies upon exposure with 14 and 24. The evaluation of 14 and 24 against chloroquine resistant strain, (Pf7GB) of P. falciparum afforded IC50 values, 13.29±1.20 and 7.21±0.98µM, respectively. The combination of 24 with artemisinin (ART) showed enhanced killing of parasite against Pf3D7. Further, all phthalimides were evaluated for their activity against falcipain-2 (FP2), a major hemoglobinase of malarial parasite. The enzymatic assay afforded 6 as most active member against FP2. To the best of our knowledge this is the initial study represents phthalimide protected amino acids functionalized with cyclic amines as potent antimalarial agents.

Multi-virulence-locus sequence typing of 4b Listeria monocytogenes isolates obtained from different sources in India over a 10-year period.

Listeria monocytogenes is an emerging foodborne pathogen responsible for listeriosis. The incidence of listeriosis has increased during the last 2 decades due to the increase in consumption of ready-to-eat foods and change in food consumption habits. Outbreaks and sporadic cases of listeriosis have been reported in developed countries. These reports have helped determine the safety practices needed to control listeriosis. Although L. monocytogenes has been reported from humans, animals, and a variety of foods in India, limited data exist with respect to prevalence and distribution of L. monocytogenes in the Indian subcontinent. The Indian Listeria Culture Collection Centre in Goa maintains all of the isolates received for subtyping and molecular characterization. Of the listerial isolate collection maintained by this center, three fourths of the isolates are of 4b serotype, while the number of other serotypes is very low. Therefore, we screened L. monocytogenes serotype 4b isolates to determine their relevance to previously defined epidemics and/or outbreaks using multi-virulence-locus sequence typing (MVLST). A total of 25 isolates in serogroup 4b of L. monocytogenes were randomly selected from a repository of 156 L. monocytogenes 4b isolates obtained from different sources in India over a period of 10 years. MVLST sequence types (virulence types, VTs) were compared to known epidemic clones and other known isolates in the L. monocytogenes MVLST database. The 25 isolates were grouped into three clusters. Cluster I comprised 21 isolates including animal (n=9), human (n=4), and food (n=8), which matched Epidemic Clone I (ECI, VT20). Three isolates-two from animal and one from food-formed a cluster while a single animal isolate was placed into two novel VTs (VT98 and VT99), respectively. Based on these findings, it can be inferred that ECI has been isolated from a variety of sources and places and has persisted in India for at least 10 years.

Efficacy and Safety of Vildagliptin and Remogliflozin as Add-on Therapy to Metformin in Patients of Type 2 Diabetes Mellitus: An open-label comparative study.

Objectives: This study aimed to evaluate the safety and efficacy of remogliflozin compared to vildagliptin as an add-on drug to metformin in type 2 diabetes mellitus (T2DM) treatment. Metformin is considered a first-line drug in T2DM. However, as the disease progresses with heightened insulin resistance and declining ß-cell function, the use of metformin alone is often inadequate to achieve optimum glucose levels. Methods: This prospective, randomised study was conducted at Maulana Azad Medical College and Associated Hospital in New Delhi, India, between February 2020 to January 2021. This study recruited 60 T2DM patients aged 35-70 years with glycated haemoglobin (HbA1c) >6.5% taking metformin at a daily dosage of 1,500-3,000 mg for ≥3 months. Patients were randomly assigned in a 1:1 ratio to receive either vildagliptin (50 mg) or remogliflozin (100 mg) twice daily for 90 days. The primary endpoint was a change in HbA1c levels from baseline to the end of 90 days whereas secondary endpoints were changes in lipid profile and weight. Results: The decrement in mean HbA1c levels was significantly higher in the remogliflozin group than in the vildagliptin group (-8.1% versus -2.4%; P <0.001). In addition, more significant weight loss was found in remogliflozin-treated patients (-5.2% versus -0.6%; P <0.01). Both treatments were well tolerated throughout the study. Conclusion: Compared to vildagliptin, remoglilflozin was significantly more effective in glycaemic control and weight loss in patients with T2DM and can therefore be considered as an add-on drug in T2DM not adequately controlled by metformin monotherapy.

Knowledge, attitudes and demographic effect on menopausal experiences among Indian rural women.

The menopausal experiences of women in selected rural areas of Visnagar, addressing a research gap within cultural and socio-economic landscapes is of interest. The global aging trend was reflected in the 26% representation of women aged 50 and over in the study. Employing a cross-sectional design, 200 menopausal women were sampled through stratified random sampling, emphasizing demographic diversity. Results from a structured Knowledge Questionnaire and a Likert Scale for Attitude revealed that women generally possessed commendable knowledge (mean score 10.94) and positive attitudes (mean score 28.66) toward menopause. Significant associations between age, education, occupation, and income with knowledge and attitudes were uncovered through chi-square tests. This study underscored the need for tailored interventions in rural settings, considering the influence of cultural, regional, and demographic factors on menopausal experiences. The findings contributed to bridging the research gap and emphasized the importance of individualized approaches for promoting the well-being of menopausal women in rural communities.

Ki 67 is an independent predictive biomarker of cancer specific and local recurrence-free survival after lung tumor ablation.

BACKGROUND: The objective of this work was to evaluate the feasibility of histopathological analysis of tissue extracted on multitined electrodes and assess whether tissue characteristics can be used as biomarkers of oncologic outcomes after lung tumor radiofrequency (RF) ablation. METHODS: Treatment-related data regarding RF ablation of lung malignancies at our institution was collected using a Health Insurance Portability and Accountability Act-compliant ablation database. Institutional review board waiver was obtained for this study. Immunohistochemical analysis of tissue extracted from the electrodes after lung tumor RF ablation was performed for proliferation (Ki-67) and apoptosis (caspase-3). Patient, tumor demographics, and ablation parameters were recorded. Local tumor progression-free survival (LPFS), disease-specific survival (DSS), and overall survival (OS) were assessed using Kaplan-Meier methodology. Multivariate analysis determined factors affecting these oncological outcomes. RESULTS: A total of 47 lung tumors in 42 patients were ablated; 30 specimens were classified as coagulation necrosis (CN) and 17 as Ki-67-positive (+) tumor cells (viable). Tumor sizes were similar in the CN and Ki-67+ groups (P = 0.32). Median LPFS was 10 versus 16 months for Ki-67+ and CN groups, and 1-year LPFS was 34 and 75 %, respectively (P = 0.003). Median OS was 20 and 46 months (P = 0.12), and median DSS was 20 and 68 months (P = 0.01) for the Ki-67 + and CN groups, respectively. Identification of Ki-67+ tumor cells more than tripled the risk of death from cancer [hazard ratio (HR) = 3.65; 95 % confidence interval (95 % CI), 1.34-9.95; P = 0.01] and tripled the risk of local tumor progression (LTP) (HR = 3.01; 95 % CI, 1.39-6.49; P = 0.005). CONCLUSIONS: Ki-67+ tumor cells on the electrode after pulmonary tumor RF ablation is an independent predictor of LTP, shorter LPFS, and DSS.
