Oral Fluid, Electrolytes, and Energy Management in Various Adult and Geriatric Illnesses beyond Diarrhea: An Indian Expert Panel Delphi Consensus Recommendation.

BACKGROUND: Dehydration is a highly prevalent clinical challenge in adults which can go undetected. Although dehydration is commonly associated with an increased risk of hospitalization and mortality, only a few international guidelines provide recommendations regarding oral fluids, electrolytes, and energy (FEE) management in adults/geriatrics with dehydration due to nondiarrheal causes. Currently, there is a lack of comprehensive recommendations on the role of oral FEE in nondiarrheal dehydration in adult and geriatric Indian patients. MATERIALS AND METHODS: A modified Delphi approach was designed using an online questionnaire-based survey followed by a virtual meeting, and another round of online surveys was used to develop this consensus recommendation. In round one, 130 statements, including 21 open-ended questions, were circulated among ten national experts who were asked to either strongly agree, agree, disagree, or strongly disagree with statements and provide responses to open-ended questions. The consensus was predefined at 75% agreement (pooling "strongly agree" and "agree" responses). Presentation of relevant literature was done during a virtual discussion, and some statements (the ones that did not achieve predefined agreement) were actively discussed and deliberately debated to arrive at conclusive statements. Those statements that did not reach consensus were revised and recirculated during round two. RESULTS: Consensus was achieved for 130/130 statements covering various domains such as assessment of dehydration, dehydration in geriatrics, energy requirement, impact of oral FEE on patient outcome, and fluid recommendations in acute and chronic nondiarrheal illness. However, one statement was not added as a recommendation in the final consensus (129/130) as further literature review did not find any supporting data. Oral FEE should be recommended as part of core treatment from day 1 of acute nondiarrheal illness and started at the earliest feasibility in chronic illnesses for improved patient outcomes. Appropriately formulated fluids with known electrolyte and energy content, quality standards, and improved palatability may further impact patient compliance and could be a good option. CONCLUSION: These consensus recommendations provide guidance for oral FEE recommendations in Indian adult/geriatric patients with various nondiarrheal illnesses.

Level of physical activity among adolescents in Ernakulam District, Kerala: A cross-sectional study.

Introduction: For children aged 5-17 years, WHO recommends moderate-to-vigorous intensity physical activity for at least 60 minutes daily which would account for 420 minutes of physical activity per week regardless of working days or holidays. With the increasing prevalence of non-communicable diseases in Kerala, this study aimed to assess the level of physical activity among high school students in Ernakulam District, Kerala. Materials and Methods: A school-based cross-sectional study was conducted among ninth and tenth standard students of two randomly selected schools in Ernakulam District. A total of 303 children were recruited for the study. Consent rate and response rate of the study were 100%. A structured questionnaire adapted from MRC-CPAQ (Children's Physical Activity Questionnaire) was used to collect the data. Results: The study revealed that out of 303 students, 72.9% were < 15 years, 77% were males, and 59% were urban residents. More than 70% of the participants were actively involved in physical activity of moderate-to-vigorous intensity. Males, in the age group of 15 years and above, having a separate play area, and those with no siblings were found to have significantly higher levels of physical activity. Conclusion: The study was able to identify a positive trend for physical activity among adolescents. Town planning and building of play areas are essential to develop and retain the habit of physical activity among adolescents.

Knowledge, attitude, and practice regarding mosquito-borne diseases among migrant laborers from a migrant settlement in Ponekkara, Ernakulam Kerala.

Background: Mosquito-borne diseases (MBDs) such as Malaria, Dengue, Chikungunya, lymphatic filariasis, and Japanese Encephalitis are important public health problems in India. Ernakulam in Kerala being a hub of construction activities has a large influx of migrants from Odisha, West Bengal, Bihar, Assam, U. P., Jharkhand, T. N., and Karnataka. Hence, the objective of this study was to assess the knowledge, attitude, and practice related to MBDs and the associated factors among the migrant laborers from a migrant settlement in Ponekkara, Ernakulam Kerala. Materials and Methods: A cross-sectional study was done among 179 migrant laborers from a migrant settlement in Ponekkara, Kerala, from September 2021 to November 2021 using a pretested semi-structured questionnaire to collect information regarding socio-demographic details and their knowledge, attitude, and practice regarding mosquito borne diseases. After taking verbal consent, the questionnaire was administered by the investigator. Descriptive and univariate analysis was done using SPSS Version 20. Results: It was found that 58.4% of the migrant laborers had poor knowledge, 55.9% had poor attitude, and 61.5% of them had poor practice regarding MBDs. On univariate analysis, a statistically significant association was observed between attitude score and the level of education. Conclusion: The findings showed that migrant laborers had an overall poor knowledge, attitude, and practices regarding MBDs. Consequently, there is a need to plan an awareness program among the migrant settlements regarding MBDs.

Seroprevalence of COVID-19 antibody among children aged 5-17 years in an urban and rural area of Ernakulam District, Kerala.

Background: The age group of 5-17 years belongs to the vulnerable segment of the population for COVID-19 infection in India. Seroprevalence in this population can therefore allow inferences to be made about the extent of infection. Objectives: The objective of this study was to assess the seroprevalence and to determine the factors associated with COVID-19 antibody among children aged 5-17 years in an urban and rural area of Kochi, Kerala. Methods: A community-based cross-sectional study was undertaken in the urban and rural field practice areas of the community medicine department in a medical college, Kochi. A semi-structured questionnaire was used to collect information about sociodemographic data, history related to COVID-19, and the severe acute respiratory syndrome coronavirus 2 antibody test result. Blood samples were collected and tested for the presence of COVID-19 antibodies using the Wantai test kit after attaining informed assent from the parent/guardian. Results: The seroprevalence of the COVID-19 antibody was 48.3% among participants. The seroprevalence of COVID-19 antibody was higher among children of mothers with skilled/unskilled occupation, residents of rural area, above poverty line category, those with a history of COVID-19, and those who had a history of contact with COVID-19-positive patients. Conclusion: Half of the study population were COVID antibody positive, and the rest were at risk of infection. Therefore, adherence to COVID-19 guidelines is essential to control further spread of infection among children.

Public health implications of Sabarimala mass gathering in India: A multi-dimensional analysis.

INTRODUCTION: Mass gathering for religious and spiritual purposes are common in India. However, mass gathering health and travel medicine is still in its infancy in India. OBJECTIVES: The study explored bio-medical, environmental and psycho-social dimensions of mass gathering in Sabarimala pilgrimage, which is annually attended by 25 million pilgrims. METHODS: In a cross sectional design, the investigators travelled the pilgrim trail and stayed in the shrine area to conduct the interviews (sample = 1259), to observe the practices as well as to assess the environmental conditions including sanitation. We did in-depth interviews of a subset of samples of the pilgrims, laboratory tests for water quality and secondary analysis of health services data. RESULT: 43.4% pilgrims reported at least one health problem. Leg pain, joint/muscle pain, breathlessness, were the common symptoms. Pilgrims expressed concern about drinking water and food safety and majority of them felt the crowd management as unsatisfactory. Untreated sewage and solid waste were found to pollute the water downstream. Average patient presentation rate for 2014-2017 was 4999.6 per 100,000 pilgrims and referral to Hospital Rate was 19 per 100,000 pilgrims. Mortality rate ranged from 18.5 to 21 per 100,000 pilgrims among those who attended the health centers for ailments. Death due to Coronary Artery Heart Disease (CAHD) has slightly decreased over the period of 3 years from 97.6% to 85.1%. CONCLUSION: Data with respect to safety, health and environment at the pilgrim sites need to be continuously assessed to understand changes and trends and to develop an effective mass gathering and safe pilgrimage policy (MGSPP).

Indian consensus on gastroesophageal reflux disease in adults: A position statement of the Indian Society of Gastroenterology.

The Indian Society of Gastroenterology developed this evidence-based practice guideline for management of gastroesophageal reflux disease (GERD) in adults. A modified Delphi process was used to develop this consensus containing 58 statements, which were generated by electronic voting iteration as well as face-to-face meeting and review of the supporting literature primarily from India. These statements include 10 on epidemiology, 8 on clinical presentation, 10 on investigations, 23 on treatment (including medical, endoscopic, and surgical modalities), and 7 on complications of GERD. When the proportion of those who voted either to accept completely or with minor reservation was 80% or higher, the statement was regarded as accepted. The prevalence of GERD in India ranges from 7.6% to 30%, being < 10% in most population studies, and higher in cohort studies. The dietary factors associated with GERD include use of spices and non-vegetarian food. Helicobacter pylori is thought to have a negative relation with GERD; H. pylori negative patients have higher grade of symptoms of GERD and esophagitis. Less than 10% of GERD patients in India have erosive esophagitis. In patients with occasional or mild symptoms, antacids and histamine H2 receptor blockers (H2RAs) may be used, and proton pump inhibitors (PPI) should be used in patients with frequent or severe symptoms. Prokinetics have limited proven role in management of GERD.

History of the Growing Burden of Cancer in India: From Antiquity to the 21st Century.

This review traces the growing burden of cancer in India from antiquity. We searched PubMed, Internet Archive, the British Library, and several other sources for information on cancer in Indian history. Paleopathology studies from Indus Valley Civilization sites do not reveal any malignancy. Cancer-like diseases and remedies are mentioned in the ancient Ayurveda and Siddha manuscripts from India. Cancer was rarely mentioned in the medieval literature from India. Cancer case reports from India began in the 17th century. Between 1860 and 1910, several audits and cancer case series were published by Indian Medical Service doctors across India. The landmark study by Nath and Grewal used autopsy, pathology, and clinical data between 1917 and 1932 from various medical college hospitals across India to confirm that cancer was a common cause of death in middle-aged and elderly Indians. India's cancer burden was apparently low as a result of the short life expectancy of the natives in those times. In 1946, a national committee on health reforms recommended the creation of sufficient facilities to diagnose and manage the increasing cancer burden in all Indian states. Trends from the Mumbai population-based cancer registry revealed a four-fold increase in patients with cancer from 1964 to 2012. Depending on the epidemiologic transition level, wide interstate variation in cancer burden is found in India. We conclude that cancer has been recognized in India since antiquity. India's current burden of a million incident cancers is the result of an epidemiologic transition, improved cancer diagnostics, and improved cancer data capture. The increase in cancer in India with wide interstate variations offers useful insights and important lessons for developing countries in managing their increasing cancer burdens.

Prevalence estimation of microsatellite instability in colorectal cancers using tissue microarray based methods - A tertiary care center experience.

AIM: Microsatellite instability (MSI) pathway is known to be implicated in carcinogenesis of 15% colorectal carcinomas (CRC), including 2%-3% of cases of Lynch syndrome, as per western literature. MSI status has important prognostic and therapeutic implications. The prevalence of MSI in Indian CRC patients is unknown. We aimed to determine the prevalence by studying 231 consecutive unselected cases of CRC. METHODS: Tissue microarrays using duplicate cores per case for 141 cases, and whole tissue sections for 90 cases, were used. Immunohistochemistry with four mismatch repair (MMR) markers - MLH1, MSH2, MSH6, and PMS2 was performed. Molecular analysis for MSI status was performed in 18 randomly selected cases. Correlation with various clinical and histopathological features was done using univariate and multivariate analysis. RESULTS: Loss of MMR immunohistochemical (IHC) was seen in 53/231 cases, i.e. 22.94% (95% confidence interval 17.52%-28.36%). MLH1-PMS2 dual loss comprised 13.9%, MSH2-MSH6 7.4%, and isolated PMS2 loss in 1.73% of cases. Univariate analysis showed significant association with age (<60 years), right-sided tumor location, histologic type, high grade, the presence of severe intratumoral lymphocytic (ITL) and peri-tumoral lymphocytic response, and N0 nodal stage. On multivariate analysis, independent variables were age < 60 years, right-sided location, and severe ITL. Molecular testing for MSI corroborated with the IHC results. CONCLUSION: The study results show a slightly higher prevalence of MSI-H phenotype, compared to Western literature, stressing the need for more widespread testing for better clinical management and identification of possible hereditary colon cancer syndrome.

Analysis and Clinical Importance of Skull Base Fractures in Adult Patients with Traumatic Brain Injury.

AIMS AND OBJECTIVES: Basal skull fracture (BSF) is rare in head injury (HI) patients and occasionally goes unnoticed which may lead to cerebrospinal fluid (CSF) fistula. With changing trends in HI, there is a need to reassess incidence and pattern of BSF pattern, CSF leak, meningitis, and management protocol, especially in this part of the world where detailed literature is lacking. SUBJECTS AND METHODS: We closely followed adult patients admitted with BSF in our institute between January 2013 and December 2014. Associated clinical features were recorded. In case of CSF leak, detailed CSF study was done and patients were managed accordingly. Patients with persistent CSF leak were managed surgically. RESULTS: During the study period, 194 of 5041 HI patients had evidence of BSF (3.85%). BSF was most commonly associated with moderate-to-severe HI (73.19%). About 81.44% patients were male and 29.9% were <30 years. Most common cause was road traffic accident (84.54%). Isolated anterior cranial fossa (ACF) fracture was most common (50%). About 63.92% patients had raccoon eyes. Forty-three patients had CSF leak with CSF rhinorrhea being more common. Culture of only 5 patients suggested bacterial meningitis. CSF leak lasted for more than 10 days in 8 patients, of which 4 patients required surgical repair. CONCLUSIONS: BSF is rare in victims of HI. It is more common in young adult males. ACF fractures are most common in our setup. Clinical signs of BSF are supportive but not definitive; high resolution computed tomography head is gold standard to detect BSF. CSF leak is rare and most of the cases can be managed conservatively. Leak persisting more than 7-10 days has high risk of developing meningitis and likely to need surgical intervention.

Assessment for learning: a needs analysis study using formative assessment to evaluate the need for curriculum reform in basic sciences.

A needs analysis study for curriculum reform in basic sciences was conducted at Melaka Manipal Medical College, India, by means of a formative assessment method, namely Basic Science Retention Examination (BSRE). Students participated in a BSRE, which comprised recall and clinical multiple-choice questions in six discipline areas. They also rated the clinical relevance of each question and provided responses to three open-text questions about the exam. Pass rates were determined; clinical relevance ratings and performance scores were compared between recall type and clinical questions to test students' level of clinical application of basic science knowledge. Text comments were thematically analyzed to identify recurring themes. Only one-third of students passed the BSRE (32.2%). Students performed better in recall questions compared with clinical questions in anatomy (51.0 vs. 40.2%), pathology (45.1 vs. 38.1%), pharmacology (41.8 vs. 31.7%), and biochemistry (43.5 vs. 26.9%). In physiology, students performed better in clinical questions compared with the recall type (56.2 vs. 45.8%). Students' response to BSRE was positive. The findings imply that transfer of basic science knowledge was poor, and that assessment methods should emphasize clinical application of basic science knowledge.

Investigating a community wide outbreak of hepatitis A in Kerala, India.

BACKGROUND: There was an outbreak of acute hepatitis in Nellikuzhy panchayat of Kothamangalam taluk, Ernakulam district, Kerala, during November and early December 2016. Objective of this study is to describe the epidemiological features of the outbreak and to identify the probable source. MATERIALS AND METHODS: The outbreak was defined in terms of time, place, and person. A hypothesis was generated and tested using a case-control study. Cases were selected by simple random sampling from the line list and controls were age-matched neighborhood individuals without any history of jaundice. Chi-square test, univariate analysis, and multi-variate logistic regression analyses were done to identify the probable risk factors. RESULTS: Around 223 hepatitis A cases were identified. Attack rate was found to be highest among the age group of 16-30 years at 1.44% and was eight times higher among males. Epidemic curve suggested a point source outbreak possibly from exposure to food or water from a newly opened hotel in the area. The case-control study confirmed the hypothesis with a statistically significant association between cases and history of exposure to food from the hotel [OR 120; 95% CI 14.6-996.2; P value < 0.001]. CONCLUSION: Observations and results of the case-control study revealed that the probable source of the Hepatitis A outbreak at Nellikuzhy panchayat was a hotel. The study findings also add evidences to the changing epidemiological pattern of hepatitis A in Kerala, and warrant the necessity to enforce food safety rules in the State.

Kytococcus sedentarius and Micrococcus luteus: highly prevalent in indoor air and potentially deadly to the immunocompromised - should standards be set?

The multifarious types of infections contracted from indoor environments show that buildings can serve as a reservoir for infectious bacteria. This study is an investigation into the type and concentrations of bacteria in the indoor and outdoor environments of an electronic factory, an office and a winery in Malaysia. Trypticase soy agar (TSA) (with ambient air incubation) and TSA supplemented with haemin and NADH (with CO2 enhanced incubation) were used for the isolation of bacteria. The plates were incubated at 37ºC for 3 days. A random selection of bacterial isolates were Gram stained and identified using the BD BBL Crystal Identification Systems. Kytococcus sedentarius and Micrococcus luteus were the predominant bacterial species identified from indoor air. These bacteria were present at relatively high concentrations in indoor air, at times, above 800 colony forming units per cubic meter (CFU/m3) of air. This indicates that both K. sedentarius and M. luteus can survive a wide range of adverse conditions, including chemical contamination and ultraviolet exposure. M. luteus is a known cause of pneumonia in immunocompromised individuals and has also been implicated in skin infections. Recent reports suggest species of kytococci as emerging opportunistic pathogens of the immunocompromised, paediatrics and the elderly. We postulate that opportunistic bacteria, such as the kytococci and the micrococci, may also have a potential role in instigating subclinical, more subtle symptoms of disease in inmmunocompetent individuals.

Bifurcated Great Saphenous Vein: A Report on Its Therapeutic and Diagnostic Perspectives.

The great saphenous vein (GSV) is the longest superficial vein in the body extending from the medial malleolus to groin skin crease level. The clinical usage of GSV has made its anatomical variations noteworthy. Since many tributaries accompany it, GSV is often mistaken with the variant vein. Duplication and persistence of accessory GSV are the two major clinically significant anatomical variations of the GSV which is frequently misinterpreted as a synonym. In the present case, we report a unique variation of GSV wherein it bifurcated into anterior and posterior divisions of two uneven calibers at knee region, which then reunited at thigh region to form a single vein before its termination into the femoral vein. Locating such variations of bifurcated GSV is a challenging task for both diagnostic and therapeutic tactics, particularly in venography procedures as it might lead to iatrogenic traumatic injury of the vessel.

Investigators' viewpoint of clinical trials in India: Past, present and future.

India's success in producing food and milk for its population (Green Revolution and White Revolution) happened because of scientific research and field trials. Likewise improving the health of Indians needs clinical research and clinical trials. A Large proportion of the sick Indians are poor, illiterate with no access to good health care. They are highly vulnerable to inducement and exploitation in clinical trials. The past two decades saw the rise and fall of clinical trials in India. The rise happened when our regulators created a favorable environment, and Indian investigators were invited to participate in global clinical trials. The gap between the demand and supply resulted in inadequate protection of the trial participants. Reports of abuses of the vulnerable trial participants followed by public interest litigations led to strengthening of regulations by the regulators. The stringent new regulations made the conduct of clinical trials more laborious and increased the cost of clinical trials in India. There was a loss of interest in sponsored clinical trials resulting in the fall in global clinical trials in India. Following repeated appeals by the investigators, the Indian regulators have recently relaxed some of the stringent regulations, while continuing to ensure the adequate patient protection. Clinical trials that are relevant to our population and conducted by well-trained investigators and monitored by trained and registered Ethics Committees will increase in the future. We must remain vigilant, avoid previous mistakes, and strive hard to protect the trial participants in the future trials.

Epidemiology of Non-Hodgkin's Lymphoma in India.

Non-Hodgkin's lymphoma (NHL) is a common hematological malignancy. The age-adjusted incidence rates for NHL in men and women in India are 2.9/100,000 and 1.5/100,000, respectively. These are about one fourth of the incidence rates reported from Western Europe or North America. Within India, the incidence is several-fold higher in urban cancer registries compared to rural areas; the incidence being higher in metropolitan cities and Indian immigrants suggesting that urban lifestyles and economic progress may increase the cancer incidence. Compared to developed nations, the key differences in the presentation in India include: median age of 54 years (almost a decade less), higher male to female ratio, higher proportion of patients with B-symptoms (40-60 vs. 20-30%), poor ECOG performance status (≥2) at diagnosis (50 vs. 20-30%), higher frequency of diffuse large B-cell lymphomas (60-70 vs. <40%), lower frequency of follicular NHL (<20 vs. 30-40%) and T-cell type in 10-20 vs. <10%. The estimated mortality rate due to NHL is higher in India than in North America and Western Europe. Diagnostic and treatment delays, incorrect diagnosis and inappropriate or suboptimal treatment may be possible reasons for the poor outcome. Any improvement in the outcomes for NHL in India will require a nationwide approach, e.g. creation of several regional and district-level centers with expertise in lymphoma management. Collection of data on patient- and disease-related characteristics, treatment outcome, development of infrastructure, centralized review of histopathology subtype, novel treatment protocols, rigorous follow-up, training of staff, and financial support towards treatment could be possible strategies to improve the outcome.

Effect of photodynamic therapy adjunct to scaling and root planing in periodontitis patients: A randomized clinical trial.

BACKGROUND: A randomized split-mouth controlled clinical trial was conducted to evaluate the efficacy of photodynamic therapy (PDT) in reducing Aggregatibacter actinomycetemcomitans (Aa) in periodontitis patients. METHODS: Twenty patients with periodontitis were recruited for the trial. Following random allocation of either quadrants of the selected jaw to test or control treatment, conventional non-surgical periodontal therapy (NSPT) was performed. In addition, the test side received adjunct photodynamic therapy. Probing depth (PD), clinical attachment level, bleeding on probing (BoP) and plaque scores (PS%) were recorded at phase 0 (baseline), phase 1 (immediately after NSPT), phase 2 (7 days following NSPT), phase 3 (1 month following NSPT) and phase 4 (3 months following NSPT). Subgingival plaque samples for quantification of Aa by real-time polymerase chain reaction was performed at phases 0, 1, 2 and 4. RESULTS: There was a significant clinical improvement at phases 3 and 4 compared with baseline while BoP reduced significantly only in the test group at phase 4. However, no difference in the quantification of Aa was detected between the groups. CONCLUSIONS: Within the limits of the study, PDT adjunct to scaling and root planing does not lead to quantitative reduction of Aa in periodontitis patients.

Primary liver cancer deaths and related years of life lost attributable to hepatitis B and C viruses in India.

BACKGROUND AND AIMS: More than 25,000 people die of liver cancer annually in India. There is little information about the contribution of hepatitis B virus (HBV) and hepatitis C virus (HCV) to these deaths. We conducted a systematic review of published studies on HBV or HCV infection and liver cancer in India and estimated the population attributable fraction (PAF) of liver cancer deaths caused by these infections and the corresponding annual number of deaths and years of life lost (YLL) in the country. METHODS: We searched the PubMed and Scopus databases, as well as the reference list of relevant articles in the systematic review. For calculation of the number of liver cancer deaths attributable to HBV and HCV, we used two sources of outcome data and two relative risks for the association between HCV and liver cancer. RESULTS: The PAF was 67% for HBV, 17-19% for HCV, and 71-72% for HBV and/or HCV. The annual attributable number of liver cancer deaths was approximately 17,000 for HBV; 4500 for HCV; and 18,500 for HBV and/or HCV, corresponding to approximately 297,000, 75,000, and 315,000 YLL, respectively. There was little difference in these numbers using the two sources of outcome data or the two risk estimates for HCV. CONCLUSIONS: Our findings underscore the importance of primary prevention of HBV and HCV by appropriate measures, including vaccination (HBV only), prevention of transfusion-related infections, and increased awareness of the routes of transmission and long-term health outcomes.
