Prevalence and Risk Factors of Urinary Incontinence among Elderly Women Residing in Kochi Corporation: A Community-based Cross-sectional Study.

Background: A study was done on the prevalence, risk factors, and treatment-seeking behavior of elderly women with urinary incontinence (UI) residing in Kochi Corporation, Kerala, India. The community-based cross-sectional study was done in Kochi on 525 elderly women aged 60 years and above, selected by cluster random sampling, after getting consent, using a questionnaire. The overall prevalence of UI was found to be 64% (95% confidence interval (CI) 59.5-67.6). The most common type of UI was found to be the urge type of incontinence (38.3%, 95% CI, 34.14-42.45). Chronic cough (odds ratio [OR] 1.754, 95% 1.170-2.631), chronic constipation (OR: 1.563, 95% CI: 1.030-2.373), obesity (OR: 1.591, 95% CI: 1.110-2.280), diabetes (OR: 1.517, 95% CI: 1.036-2.222), and taking medications for diabetes and hypertension (OR: 1.476, 95% 1.008-2.163) were found to be risk factors of UI. Multiparity (OR: 1.757, 95% CI: 1.073-2.876), delivery at home (OR: 1.761, 95% CI: 1.205-2.575), undergoing any pelvic surgery (OR: 1.504, 95% CI: 1.052-2.150) were the gynecological and obstetric factors associated with UI. Context: Very few community-based studies are available on UI among elderly women. Aim: The primary objective of the study was to estimate the prevalence of UI among elderly women residing in the Kochi corporation. The secondary objective was to determine the risk factors of UI. Settings and Design: A community-based cross-sectional study was done in the Kochi Corporation of Ernakulam district. Subjects and Methods: A pilot study was conducted and based on this, the sample size was computed to be 72.41. Data from 525 individuals were collected using cluster random sampling. A questionnaire for urinary incontinence diagnosis questionnaire was used for assessing the type of UI. Statistical Analysis Used: Percentage prevalence, Chi-square test. Results: The overall prevalence of UI was found to be 64%. The most common type of UI was found to be the urge type of incontinence. Chronic cough, chronic constipation, obesity, diabetes, taking medications for diabetes, and hypertension were found to be risk factors of UI. Multiparity, delivery at home, and undergoing any pelvic surgery were the gynecological and obstetric factors associated with UI. Conclusions: The prevalence of UI among elderly women in this study was found to be 63.9%. The most common type of UI was found to be urge type of incontinence 38.3%, followed by mixed incontinence 32.3%, and stress incontinence 29.3%. Chronic cough (OR: 1.754), chronic constipation (OR: 1.563), obesity (OR: 1.591), diabetes (OR: 1.517), and taking medications for diabetes and hypertension (OR: 1.476) were found to be risk factors for UI. Multiparity (OR: 1.757), delivery at home (OR: 1.761) and undergoing any pelvic surgery (OR: 1.504) were the gynecological and obstetric factors associated with UI among elderly women in this study. Chronic cough (adjusted odds ratio [aOR] 1.64, 95% CI: 1.08-2.50), obesity (aOR: 1.64, 95% CI: 1.13-2.39), pelvic surgery (aOR: 1.64, 95% CI: 1.13-2.39), and delivery at home (aOR: 1.89, 95% CI: 1.27-2.82) were found to be independent risk factors for UI among elderly women.

Targeting the Structural Integrity of Extracellular Vesicles via Nano Electrospray Gas-Phase Electrophoretic Mobility Molecular Analysis (nES GEMMA).

Extracellular vesicles (EVs) are in the scientific spotlight due to their potential application in the medical field, ranging from medical diagnosis to therapy. These applications rely on EV stability during isolation and purification-ideally, these steps should not impact vesicle integrity. In this context, we investigated EV stability and particle numbers via nano electrospray gas-phase electrophoretic mobility molecular analysis (nES GEMMA) and nanoparticle tracking analysis (NTA). In nES GEMMA, native, surface-dry analytes are separated in the gas-phase according to the particle size. Besides information on size and particle heterogeneity, particle number concentrations are obtained in accordance with recommendations of the European Commission for nanoparticle characterization (2011/696/EU, 18 October 2011). Likewise, and in contrast to NTA, nES GEMMA enables detection of co-purified proteins. On the other hand, NTA, yielding data on hydrodynamic size distributions, is able to relate particle concentrations, omitting electrolyte exchange (and resulting EV loss), which is prerequisite for nES GEMMA. Focusing on EVs of different origin, we compared vesicles concentrations and stability, especially after electrolyte exchange and size exclusion chromatography (SEC). Co-isolated proteins were detected in most samples, and the vesicle amount varied in dependence on the EV source. We found that depletion of co-purified proteins was achievable via SEC, but was associated with a loss of EVs and-most importantly-with decreased vesicle stability, as detected via a reduced nES GEMMA measurement repeatability. Ultimately, we propose the repeatability of nES GEMMA to yield information on EV stability, and, as a result, we propose that nES GEMMA can yield additional valuable information in EV research.

A possible role of gas-phase electrophoretic mobility molecular analysis (nES GEMMA) in extracellular vesicle research.

The emerging role of extracellular vesicles (EVs) as biomarkers and their envisioned therapeutic use require advanced techniques for their detailed characterization. In this context, we investigated gas-phase electrophoresis on a nano electrospray gas-phase electrophoretic mobility molecular analyzer (nES GEMMA, aka nES differential mobility analyzer, nES DMA) as an alternative to standard analytical techniques. In gas-phase electrophoresis, single-charged, surface-dry, native, polydisperse, and aerosolized analytes, e.g., proteins or bio-nanoparticles, are separated according to their electrophoretic mobility diameter, i.e., globular size. Subsequently, monodisperse particles are counted after a nucleation step in a supersaturated atmosphere as they pass a focused laser beam. Hence, particle number concentrations are obtained in accordance with recommendations of the European Commission for nanoparticle characterization (2011/696/EU from October 18th, 2011). Smaller sample constituents (e.g., co-purified proteins) can be detected next to larger ones (e.g., vesicles). Focusing on platelet-derived EVs, we compared different vesicle isolation techniques. In all cases, nanoparticle tracking analysis (NTA) confirmed the presence of vesicles. However, nES GEMMA often revealed a significant co-purification of proteins from the sample matrix, precluding gas-phase electrophoresis of less-diluted samples containing higher vesicle concentrations. Therefore, mainly peaks in the protein size range were detected. Mass spectrometry revealed that these main contaminants belonged to the group of globulins and coagulation-related components. An additional size exclusion chromatography (SEC) step enabled the depletion of co-purified, proteinaceous matrix components, while a label-free quantitative proteomics approach revealed no significant differences in the detected EV core proteome. Hence, the future in-depth analysis of EVs via gas-phase electrophoresis appears feasible. Platelet-derived extracellular vesicles (EVs)with/without additional size exclusion chromatographic (SEC) purification were subjected to nanoparticle tracking analysis (NTA) and gas-phase electrophoresis (nES GEMMA). The latter revealed presence of co-purified proteins, targetable via mass spectrometry (MS). MS also revealed that SEC did not influence EV protein content. To conclude, nES GEMMA is a valuable tool for quality control of EV-containing samples under native conditions allowing for detection of co-purified proteins from complex matrices.

Comparative Analysis of Platelet-Derived Extracellular Vesicles Using Flow Cytometry and Nanoparticle Tracking Analysis.

Growing interest in extracellular vesicles (EVs) has prompted the advancements of protocols for improved EV characterization. As a high-throughput, multi-parameter, and single particle technique, flow cytometry is widely used for EV characterization. The comparison of data on EV concentration, however, is hindered by the lack of standardization between different protocols and instruments. Here, we quantified EV counts of platelet-derived EVs, using two flow cytometers (Gallios and CytoFLEX LX) and nanoparticle tracking analysis (NTA). Phosphatidylserine-exposing EVs were identified by labelling with lactadherin (LA). Calibration with silica-based fluorescent beads showed detection limits of 300 nm and 150 nm for Gallios and CytoFLEX LX, respectively. Accordingly, CytoFLEX LX yielded 40-fold higher EV counts and 13-fold higher counts of LA+CD41+ EVs compared to Gallios. NTA in fluorescence mode (F-NTA) demonstrated that only 9.5% of all vesicles detected in scatter mode exposed phosphatidylserine, resulting in good agreement of LA+ EVs for CytoFLEX LX and F-NTA. Since certain functional characteristics, such as the exposure of pro-coagulant phosphatidylserine, are not equally displayed across the entire EV size range, our study highlights the necessity of indicating the size range of EVs detected with a given approach along with the EV concentration to support the comparability between different studies.

Extracellular Vesicles Derived From Platelets, Red Blood Cells, and Monocyte-Like Cells Differ Regarding Their Ability to Induce Factor XII-Dependent Thrombin Generation.

As transmitters of biological information, extracellular vesicles (EVs) are crucial for the maintenance of physiological homeostasis, but also contribute to pathological conditions, such as thrombotic disorders. The ability of EVs to support thrombin generation has been linked to their exposure of phosphatidylserine, an anionic phospholipid that is normally restricted to the inner leaflet of the plasma membrane but exposed on the outer leaflet during EV biogenesis. Here, we investigated whether EVs of different cellular origin and from different settings, namely platelets and red blood cells from blood bank units and a monocyte-like cell line (THP-1), differ regarding their potential to support factor XII-dependent thrombin generation. EVs were isolated from blood products or THP-1 cell culture supernatants using differential centrifugation and characterized by a combination of flow cytometry, nanoparticle tracking analysis, and Western blotting. Soluble factors co-enriched during the isolation of EVs were depleted from blood-cell derived EV fractions using size exclusion chromatography, while proteins bound to the surface of EVs were degraded by mild protease treatment. We found that platelet-derived and red blood cell-derived EVs supported factor XII-dependent thrombin generation to comparable extents, while monocytic EVs failed to support thrombin generation when added to EV-depleted human plasma. We excluded a major contribution of co-enriched soluble proteins or of proteins bound to the EV surface to the thrombogenicity of blood cell-derived EVs. Our data suggest that the enhanced potential of blood cell-derived EVs to support thrombin generation is rather due to enhanced exposure of phosphatidylserine on the surface of blood cell-derived EVs. Extending these investigations to EVs from other cell types, such as mesenchymal stromal cells, will be crucial for their future therapeutic applications.

Switching to a Healthy Diet Prevents the Detrimental Effects of Western Diet in a Colitis-Associated Colorectal Cancer Model.

Inflammatory bowel disease increases the odds of developing colitis-associated cancer. We hypothesized that Western-style diet (WD) aggravates azoxymethane (AOM)/dextran sulfate sodium salt (DSS)-induced colitis-associated tumorigenesis and that switching to the standard AIN93G diet will ameliorate disease symptoms even after cancer initiation. Female BALB/c mice received either WD (WD group) or standard AIN93G diet (AIN group) for the whole experimental period. After five weeks, the mice received 12.5 mg/kg AOM intraperitoneally, followed by three DSS cycles. In one group of mice, the WD was switched to AIN93G the day before starting the first DSS cycle (WD/AIN group). Feeding the WD during the whole experimental period aggravated colitis symptoms, shortened the colon (p < 0.05), changed microbiota composition and increased tumor promotion. On molecular level, the WD reduced proliferation (p < 0.05) and increased expression of the vitamin D catabolizing enzyme Cyp24a1 (p < 0.001). The switch to the AIN93G diet ameliorated this effect, reflected by longer colons, fewer (p < 0.05) and smaller (p < 0.01) aberrant colonic crypt foci, comparable with the AIN group. Our results show that switching to a healthy diet, even after cancer initiation is able to revert the deleterious effect of the WD and could be an effective preventive strategy to reduce colitis symptoms and prevent tumorigenesis.

Prevalence and Pattern of Antibiotic Self-Medication Practice in an Urban Population of Kerala, India: A Cross-sectional Study.

BACKGROUND: Self-medication involves the use of medicinal products by a consumer to treat self-recognized disorders or symptoms or intermittent or continued use of a medication prescribed by a physician for chronic or recurring diseases or symptoms. Practicing self-medication for antibiotics is a major factor fueling the emergence of drug resistance. This study would help health-care providers in creating public awareness on the dangers of antibiotic abuse. OBJECTIVES: The aim of the study was to assess the prevalence and pattern of antibiotic self-medication in an urban population of Kerala. MATERIALS AND METHODS: A community-based cross-sectional study was carried out in Thrippunithura municipality, Kerala. Data were collected from 755 adults by face-to-face interview using a questionnaire after obtaining consent. Data were entered in Excel and were analyzed using SPSS. RESULTS: The percentage of respondents who practiced antibiotic self-medication was 3.31%. Males (4.1%), graduates (3.8%), and skilled workers (8.5%) were found to practice antibiotic self-medication. Majority took self-medication for sore throat (25%). Azithromycin (39%) was the major antibiotic used. Among the respondents, 36% used doctor's previous prescription to get antibiotics. The reason for antibiotic self-medication reported by majority was convenience (41%). CONCLUSION: Health education must be given to graduates and professionals, highlighting the problems due to antibiotic self-medication. With danger of antibiotic resistance developing, this is a major threat that has to be addressed urgently.

Long-Term Morbidity after Endometrial Cancer Surgery: a Comparison of Open vs. Robotic Approach.

This retrospective study is looking into the long-term morbidity after endometrial cancer staging surgery and compares the long-term morbidity of patients who underwent open staging surgery vs. robotic approach. One hundred twenty-nine patients who underwent staging surgery for endometrial cancer from January 2014 until June 2017 were included in the analysis. Morbidities occurring 1 month after surgery-vault complications, incisional hernias, vault dehiscence, and lymphedema-were looked into. There were no statistically significant differences between the long-term complications in both groups (vault infection 5.1% vs. 1.4%, vaginal cuff dehiscence 1.6% vs. 0%, incisional hernia 6.8% vs. 0%, and lymphedema 11.8% vs. 10% in open vs robotic groups respectively). But as far as clinical significance was concerned, patients who underwent robotic staging surgery had a significant decrease in vaginal cuff complications and incisional hernia. Our study shows that robotic-assisted surgery can reduce even long-term morbidity in patients undergoing surgery for endometrial cancer.

Multi-gene testing in neurological disorders showed an improved diagnostic yield: data from over 1000 Indian patients.

BACKGROUND: Neurological disorders are clinically heterogeneous group of disorders and are major causes of disability and death. Several of these disorders are caused due to genetic aberration. A precise and confirmatory diagnosis in the patients in a timely manner is essential for appropriate therapeutic and management strategies. Due to the complexity of the clinical presentations across various neurological disorders, arriving at an accurate diagnosis remains a challenge. METHODS: We sequenced 1012 unrelated patients from India with suspected neurological disorders, using TruSight One panel. Genetic variations were identified using the Strand NGS software and interpreted using the StrandOmics platform. RESULTS: We were able to detect mutations in 197 genes in 405 (40%) cases and 178 mutations were novel. The highest diagnostic rate was observed among patients with muscular dystrophy (64%) followed by leukodystrophy and ataxia (43%, each). In our cohort, 26% of the patients who received definitive diagnosis were primarily referred with complex neurological phenotypes with no suggestive diagnosis. In terms of mutations types, 62.8% were truncating and in addition, 13.4% were structural variants, which are also likely to cause loss of function. CONCLUSION: In our study, we observed an improved performance of multi-gene panel testing, with an overall diagnostic yield of 40%. Furthermore, we show that NGS (next-generation sequencing)-based testing is comprehensive and can detect all types of variants including structural variants. It can be considered as a single-platform genetic test for neurological disorders that can provide a swift and definitive diagnosis in a cost-effective manner.

Anemia Among School Children in Ernakulam District, Kerala, India.

Anaemia has significant negative impact on the health of school children including poor scholastic performance and cognitive impairment. The present study was done with the objective to estimate the prevalence of anemia among school going children in Ernakulam district, Kerala and to determine a few factors associated with anemia. Hemoglobin of 880 students of 6th to 9th standard in 11 randomly selected schools of Ernakulam district was estimated using HemoCue 201 photometer. Prevalence of anaemia was expressed using frequencies and percentages. Univariate analysis for factors associated with anemia was done. Selected variables were entered into a logistic regression model. The prevalence of anemia was estimated to be 44% (95% CI 40.67-47.33). Among them 0.8% had severe anemia, 3.5% had moderate anemia and 39.7% had mild anemia. Among them 21.3% and 52.6% reported not in the habit of consuming green leafy vegetables and citrus fruits respectively, at least three times on a usual week. Anemia among children was associated with female gender (adjusted OR 1.53, 95% CI 1.16-2.04), higher age group (adjusted OR 2.24, 95% CI 1.69-2.91) and regular intake of tea/coffee along with major meals (adjusted OR 1.62, 95% CI 1.20-2.04). Anemia among school going children in Ernakulam remains a public health problem and was more among females, higher age groups (12-15 years) and those reported regular intake of tea/coffee along with major meals. The consumption of iron rich foods among the students was poor. Behavior change communication for dietary modification and universal supplementation of iron is warranted.

Assessment of vaccine coverage and associated factors among children in urban agglomerations of Kochi, Kerala, India.

CONTEXT: Urban population in India is growing exponentially. The public sector urban health delivery system has so far been limited in its reach and is far from adequate. AIMS: This study aims to estimate routine immunization coverage and associated factors among children (12-23 months and 60-84 months) in the urban Kochi Metropolitan Area of Kerala. SETTINGS AND DESIGN: A cross-sectional study was conducted in Kochi Metropolitan area. MATERIALS AND METHODS: A cluster sampling technique was used to collect data on immunization status from 310 children aged between 12 and 23 months and 308 children aged between 60 and 84 months. STATISTICAL ANALYSIS: Crude coverage details for each vaccine were estimated using percentages and confidence intervals. Bivariate and multivariate analysis were conducted to identify factors associated with immunization coverage. RESULTS: Among the children aged 12-23 months, 89% (95% CI 85.5%-92.5%) were fully immunized, 10% were partially immunized, and 1% unimmunized. Less than 10 years of schooling among mothers (OR 2.40, 95% CI 1.20-4.81) and living in a nuclear family (OR 1.72, 95% CI 1.06-3.14) were determinants associated with partial or unimmunization of children as per multivariate analysis. The coverage of individual vaccines was found to decrease after 18 months from 90% to 75% at 4-5 years for Diphtheria Pertussis Tetanus (DPT) booster. Bivariate analysis found lower birth order and belonging to the Muslim religion as significant factors for this decrease. CONCLUSION: Education of the mother and nuclear families emerged as areas of vulnerability in urban immunization coverage. Inadequate social support and competing priorities with regard to balancing work and home probably lead to delay or forgetfulness in vaccination. Therefore, a locally contextualized comprehensive strategy with strengthening of the primary health system is needed to improve the immunization coverage in urban areas.

Prevalence of Neglected Tropical Diseases (Leishmaniasis and Lymphatic Filariasis) and Malaria Among a Migrant Labour Settlement in Kerala, India.

Neglected tropical diseases (visceral leismaniasis, lymphatic filariasis) and malaria are endemic in northern states of India. Kerala has become a hub of construction activities employing a large number of migrants from these endemic states. Studies on morbidity pattern among migrants in Kerala are lacking. It is essential to look into the burden of these infections among migrant laborers who can act as reservoirs and are a threat to native population. A cross sectional study was done among migrant laborers in Ernakulam district, Kerala. After getting informed consent, a questionnaire was administered to each participant to collect sociodemographic details and 5 ml of blood was collected for detection of antigens using rapid diagnostic tests (RDT). Of the 309 migrants tested, none of them were positive for leishmaniasis, while 3.8% were positive for malaria and 3.6% for filariasis. With 2.5 million migrant laborers in Kerala, the magnitude of the problem in absolute numbers is enormous. Active surveillance and treatment is needed to prevent the reemergence of these diseases in Kerala.

Implementation of a standardized electronic tool improves compliance, accuracy, and efficiency of trainee-to-trainee patient care handoffs after complex general surgical oncology procedures.

BACKGROUND: Duty-hour regulations have increased the frequency of trainee-trainee patient handoffs. Each handoff creates a potential source for communication errors that can lead to near-miss and patient-harm events. We investigated the utility, efficacy, and trainee experience associated with implementation of a novel, standardized, electronic handoff system. METHODS: We conducted a prospective intervention study of trainee-trainee handoffs of inpatients undergoing complex general surgical oncology procedures at a large tertiary institution. Preimplementation data were measured using trainee surveys and direct observation and by tracking delinquencies in charting. A standardized electronic handoff tool was created in a research electronic data capture (REDCap) database using the previously validated I-PASS methodology (illness severity, patient summary, action list, situational awareness and contingency planning, and synthesis). Electronic handoff was augmented by direct communication via phone or face-to-face interaction for inpatients deemed "watcher" or "unstable." Postimplementation handoff compliance, communication errors, and trainee work flow were measured and compared to preimplementation values using standard statistical analysis. RESULTS: A total of 474 handoffs (203 preintervention and 271 postintervention) were observed over the study period; 86 handoffs involved patients admitted to the surgical intensive care unit, 344 patients admitted to the surgical stepdown unit, and 44 patients on the surgery ward. Implementation of the structured electronic tool resulted in an increase in trainee handoff compliance from 73% to 96% (P < .001) and decreased errors in communication by 50% (P = .044) while improving trainee efficiency and workflow. CONCLUSION: A standardized electronic tool augmented by direct communication for higher acuity patients can improve compliance, accuracy, and efficiency of handoff communication between surgery trainees.

Assessing Compliance With Established Pneumonia Core Measures at a Comprehensive Cancer Center.

Healthcare organizations use Pneumonia Core Measures (PCMs) to ensure delivery of high-quality care. In this study, a multidisciplinary team was organized to optimize care and enhance compliance in a comprehensive cancer emergency center. We performed a four-phase study, three of which were interventional: intense education regarding PCM; microbiologic analysis of the pathogens responsible for the pneumonias; development and implementation of an institutional pneumonia algorithm and order set. In phase 4, we analyzed five PCMs. The percentage of pneumonia patients from whom blood cultures were obtained increased from 73% to 91% after intervention (p < .001); sputum cultures increased from baseline 24.6% to 51% (p = .004) post order-set implementation, and order-set utilization increased from 40% to 77%. We achieved the benchmark for only one PCM, PN 3a. More than 80% of patients met clinical and microbiological criteria for healthcare-associated pneumonia. We identified a gap between our patient population and some PCMs that relates to antibiotics selection. The treatment of cancer patients and pneumonia falls outside established guidelines for treating community-acquired pneumonia. Although the algorithm and order set implemented optimized care and minimized variation, national benchmarks for four of the PCMs were not met. Our findings provide information for policymakers considering pneumonia measurements for antibiotic selection in a cancer care setting.
