Basal Cell Adenocarcinoma - 2 Case Series of a Rare Entity

Introduction: Basal cell adenocarcinoma is a rare well recognized low grade malignant salivary gland tumor often resembles basal cell adenoma. the infiltrating growth pattern and likelihood of vascular and perineural involvement distinguishes basal cell adenocarcinoma with basal cell adenoma. Case presentation: Here we present histopathological and immune histochemical analysis of two such rare cases of basal cell adenocarcinoma and review of literature is discussed. Conclusion: Basal cell adeno carcinoma is a low grade malignancy and doesn’t metastasize. With only few hundreds of cases that has been reported in literature, basal cell adeno carcinoma should be included as differential diagnosis in salivary gland tumors in order not to miss the diagnosis

Schisandrol A and gomisin N from Schisandra chinensis extract improve hypogonadism via anti-oxidative stress in TM3 Leydig cells

BACKGROUND/OBJECTIVES@#Male hypogonadism is a condition where the body does not produce enough testosterone and significantly impacts health. Age, obesity, genetics, and oxidative stress are some physiological factors that may contribute to testosterone deficiency.Previous studies have shown many pharmacological benefits of Schisandra chinensis (S. chinensis) Baillon as an anti-inflammatory and antioxidant. However, the molecular mechanism of attenuating hypogonadism is yet to be well established. This research was undertaken to study the effects of S. chinensis extract (SCE) on testosterone deficiency.MATERIALS/METHODS: S. chinensis fruit was pulverized and extracted using 60% aqueous ethanol. HPLC analysis was performed to analyze and quantify the lignans of the SCE. @*RESULTS@#The 2,2-diphenyl-2-picrylhydrazyl and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) scavenging assays confirmed that the SCE and its major lignans (schisandrol A and gomisin N) inhibit oxidative stress. Effects of SCE analysis on the testosterone level under oxidative stress conditions revealed that both schisandrol A and gomisin N were able to recover the lowered testosterone levels. Through mRNA expression of TM3 Leydig cell, we observed that the SCE lignans were able to induce the enzymes involved in testosterone biosynthesis-related genes such as 3β-HSD4 (P < 0.01 for SCE, and P < 0.001 for schisandrol A and gomisin N), 17β-HSD3 (P < 0.001 for SCE, schisandrol A and gomisin N), and 17, 20-desmolase (P < 0.01 for schisandrol A, and P < 0.001 for SCE and gomisin N). @*CONCLUSIONS@#These results support that SCE and its active components could be potential therapeutic agents for regulating and increasing testosterone production.

The Association Between Serum Vitamin D Levels and Serum Cathelicidin Antimicrobial Peptide (CAMP) Levels Among Tuberculosis Patients in Comparison with Control Subjects

Objectives: To compare the serum vitamin D and serum cathelicidin antimicrobial peptide (CAMP) levels among tuberculosis patients and healthy subjects and to determine the association between serum vitamin D and cathelicidin in tuberculosis. Materials and Methods: This is a case-control study carried out at the pulmonary medicine and pediatrics departments of a tertiary care hospital in Chengalpattu. The study included 180 tuberculosis cases and 90 control subjects of both sexes between the age group of 1 to 80 years. Serum was used to estimate vitamin D and CAMP. The study was analyzed using SPSS version 21 (IBM Corp. Armonk, New York). The results were evaluated using the chi-square test at a 95% confidence interval, and P value <.05 was considered highly significant. Results: This study observed vitamin D deficiency, vitamin D insufficiency, and optimum vitamin D among 55%, 41%, and 3.89% tuberculosis cases, respectively. Similarly, vitamin D deficiency, vitamin D insufficiency, and optimum vitamin D were seen in 40%, 50%, and 10% healthy controls, respectively. Conclusion: This study found no association between serum vitamin D and serum CAMP levels in tuberculosis patients and healthy controls.

Wheelchair basketball improves the treatment of urinary tract infection in people with motor disabilities: a clinical trial

SUMMARY OBJECTIVE: Few studies on physical medicine and rehabilitation analyze the benefit of wheelchair basketball in people with motor disabilities. Given these, this study aimed to investigate the effect of the intervention of wheelchair basketball on urinary tract infection in people with motor disabilities. METHODS: A 12-month experimental follow-up was conducted in a single-center study. A total of 48 male individuals aged 18-55 years were allocated to the control group and experimental group. The experimental group practiced wheelchair basketball for 2 h, twice a week. Intra- and intergroup comparisons were made pre- and post-interventions over urinary tract infection. RESULTS: There was a significant improvement in urinary tract infection and urine culture in pre- and post-intervention antibiograms, respectively. Moreover, the intergroup comparison presented a decrease in infection caused by Klebsiella pneumoniae, as well as an increase in the time variability of partially activated thromboplastin, average corpuscular hemoglobin, and hemoglobin and platelets. In the experimental group, there was an increase in hemoglobin and hematocrit and a decrease in glycated hemoglobin (%HbA1C). On the intragroup comparison, there was a reduction of triiodothyronine (T3), %HbA1C, interleukin-6 pre-intervention, and C-reactive protein post-intervention. CONCLUSIONS: There was a decrease in urinary tract infection and improvement in biochemical, immunological, and microbiological biomarkers evaluated with physical exercise practice by wheelchair basketball, as well as by multiprofessional follow-up and health guidance.

Prevalence of molecular and serological tests of the new coronavirus (SARS-CoV-2) in Carlos Chagas laboratory - Sabin group in Cuiabá

SUMMARY BACKGROUND: Coronavirus disease 2019, which is caused by the new severe acute respiratory syndrome coronavirus 2, became a pandemic in 2020 with a mortality rate of 2% and high transmissibility, thus making studies with an epidemiological profile essential. OBJECTIVES: The aim of this study was to characterize the population that performed the severe acute respiratory syndrome coronavirus 2 molecular and serological tests in Carlos Chagas Laboratory - Sabin Group in Cuiabá. METHODS: A retrospective cross-sectional study was carried out with all the samples collected from nasal swab tested by RT-PCR and serological for severe acute respiratory syndrome coronavirus 2 IgM/IgG from the population served between April and December 2020. FINDINGS: In the analysis period, 23,631 PCR-coronavirus disease 2019 examinations were registered. Of this total number of cases, 7,649 (32.37%) tested positive, while 15,982 (66.31%) did not detect viral RNA and 374 of the results as undetermined. The peak of positive RT-PCR performed in July (n=5,878), with 35.65% (n=2,096). A total of 8,884 tests were performed on serological test SOROVID-19, with a peak of 1,169 (57.16%) of the positive tests for severe acute respiratory syndrome coronavirus 2 in July. MAIN CONCLUSIONS: Molecular positivity and serological tests, both peaked in July 2020, were mostly present in women aged 20-59 years, characterizing Cuiabá as the epicenter of the Midwest region in this period due to the high rate of transmissibility of severe acute respiratory syndrome coronavirus 2.

Humoral response to viral vector COVID-19 vaccine in hemodialysis patients

The coronavirus disease 2019 (COVID-19) vaccine is not readily available in many countries where dosing interval is spaced more than ideal. Patients with chronic kidney disease, especially those on maintenance hemodialysis, have a tendency for a reduced immune response. This study was undertaken to demonstrate the distinct humoral immune response to the viral vector COVID-19 vaccine in patients with kidney failure receiving maintenance hemodialysis. Methods: The study was carried out with two cohorts: 1) patients receiving maintenance hemodialysis and 2) healthcare workers from the same dialysis center as controls, each group with 72 subjects. Participants received a dose of Covishield ChAdOx1 nCoV-19 coronavirus vaccine. The humoral immunological response was determined using electrochemiluminescence immunoassay which quantitatively measures antibodies to the severe acute respiratory syndrome coronavirus 2 spike protein receptor-binding domain. Results: All study subjects in the control group developed a humoral response (antibody titer of ≥0.8 U/mL), while only 64 of 72 in the dialysis group (88.9%) were responders. Age (ρ = –0.234, p = 0.04) and sodium level (ρ = 0.237, p = 0.04) correlated with low antibody titer in bivariate analysis. In multivariate analysis, only age (odds ratio, 1.10; 95% confidence interval, 1.01–1.22; p = 0.045) was associated with nonresponders. Conclusion: Our study demonstrated a weak antibody response of hemodialysis patients to the viral vector COVID-19 vaccine. Older age was associated with nonresponders. Evaluation of both humoral and cellular immunity after the second vaccine dose and serial antibody titers can help determine the need for booster shots.

Niveles de estrés de endodoncistas de la India durante la pandemia COVID-19 / Stress Levels of Indian Endodontists during COVID-19 Pandemic

RESUMEN Introducción: La COVID-19 se propaga por vías respiratorias y aerosoles. La pandemia originada por esta enfermedad causa pánico, miedo y estrés en todos los estratos de la sociedad. Al igual que todas las demás profesiones médicas, los dentistas, particularmente los endodoncistas, que están muy expuestos a los aerosoles, pueden mostrar estrés. Objetivo: Encuestar a los endodoncistas indios para comprender mejor sus niveles de estrés psicológico durante el confinamiento de la India durante la pandemia de la COVID-19. Métodos: Del 8 de abril al 16 de abril de 2020 se realizó una encuesta cerrada en las redes sociales de endodoncia. Se utilizó la técnica de muestreo de bola de nieve. Asimismo, se recolectaron datos demográficos básicos, entorno de práctica y otras informaciones relevantes. El estrés psicológico y la angustia percibida se calcularon a través del índice de angustia peritraumática COVID-19 y la escala de estrés percibido. El análisis de regresión multinomial se realizó para estimar la tasa de riesgo relativo y p ≤ 0,05 se consideró significativo. Resultados: Este estudio tuvo 586 endodoncistas indios que completaron esta encuesta. De estos, 311 (53,07 por ciento) eran hombres, 325 (55 por ciento) en el grupo de edad de 25-35 años, 64 por ciento en áreas urbanas, 13,14 por ciento en prácticas individuales y un cuarto de ellos eran residentes. Las mujeres endodoncistas tenían un alto estrés percibido (RRR = 2,46, p = 0,01) en comparación con los hombres, medido por PSS. Los endodoncistas más jóvenes < 25 años (RRR = 9,75; p = 0,002) y 25-35 años (RRR = 4.60; p = 0,004) en comparación con el grupo de edad > 45 años tenían más angustia. Los consultores exclusivos tuvieron RRR = 2,90, p = 0,02, para la angustia leve a moderada en comparación con la normal. Se consideran los factores que impulsan este fenómeno. Conclusiones: Durante el cierre debido a la COVID-19, los endodoncistas indios 1-en-2 tuvieron angustia, según lo medido por CPDI y 4 de cada 5 percibieron estrés, según lo indicado por PSS. Nuestro modelo identificó ciertos factores que impulsan el (des)estrés, lo que ayudaría a los formuladores de políticas a iniciar una respuesta adecuada(AU)

ABSTRACT Background: The novel 2019 COVID-19 spreads by respiratory and aerosols. COVID-19 driven pandemic causes panic, fear and stress among all strata of society. Like all other medical professions, dentists, particularly endodontists, who are highly exposed to aerosols would be exposed to stress. Objective: To survey the Indian endodontists to better understand their levels of psychological stress during the Indian lockdown COVID-19 Pandemic. Methods: From 8th April to 16th April 2020, we conducted an online survey in closed endodontic social media using snowball sampling technique, collecting basic demographic data, practice setting and relevant data. Psychological stress and perceived distress were collected through COVID-19 Peri-traumatic Distress Index and Perceived stress scale. Multinomial regression analysis was performed to estimate relative risk rate and p ≤ 0.05 was considered significant. Results: This study had 586 Indian endodontists completing this survey across India. Of these, 311(53.07 percent) were males, 325(55 percent) in the age group of 25-35 years, 64 percent in urban areas, 13.14 percent in solo-practice and a fourth of them were residents. Female endodontists had high perceived stress (RRR = 2.46, p = 0.01) as compared to males, as measured by PSS. Younger endodontists < 25 years (RRR = 9.75; p = 0.002) and 25-35years (RRR = 4.60; p = 0.004) as compared with > 45 years age-group had more distress. Exclusive consultants had RRR = 2.90, p = 0.02, for mild-to-moderate distress as compared to normal. Factors driving this phenomenon are considered. Conclusions: During the lock down due to COVID-19, 1-in-2 Indian endodontists had distress, as measured by CPDI and 4-in-5 of them had perceived stress, as indicated by PSS. Our model identified certain factors driving the (dis)stress, which would help policy framers to initiate appropriate response(AU)

Role of electrocardiogram in identifying the infarct related artery in acute myocardial infarction and to correlate it with 2D echo and coronary angiogram

Background: The Electrocardiogram remains a crucial tool in the identification and management of acute myocardial infarction. A detailed analysis of patterns of ST segment elevation may influence decisions regarding the perfusion therapy. This study was undertaken to study the role of ECG in identifying the infarct related artery in acute ST elevation MI and to correlate its findings with 2 D ECHO and Coronary angiogram.Methods: A total of 100 patients who presented with acute ST elevation MI were randomly selected for the study. After admission all the patients underwent ECG, CPK, CK-MB levels, 2D ECHO and CAG. Patients with ST segment elevation from ECG was evaluated to identify culprit vessel and the ECG findings were then correlated with 2D ECHO and CAG to identify the Sensitivity, Specificity, Positive predictive value and Negative predictive value of ECG in identifying the infarct related artery.Results: Fifty-two (52%) patients had an Anterior wall MI, forty-two patients (42%) had an evidence of Inferior wall MI and Six patients (6%) were found to have Antero inferior wall MI in the study group. Thirty-eight (38%) had evidence of SVD, forty-six patients (46%) had DVD and Sixteen patients (16%) had TVD. Sensitivity, Specificity, PPV and NPV of the ECG in identifying the LAD artery occlusion were 60.5%, 100%, 100% and 44.4% respectively. Sensitivity, Specificity, PPV and NPV of ECG in identifying the RCA artery occlusion were 78.5%, 100%, 100% and 78.5% respectively. Sensitivity, Specificity, PPV and NPV of the ECG in identifying the LCx artery occlusion were 26%, 96%, 86% and 60% respectively.Conclusions: ECG was found to be a sensitive and specific tool in identifying the infarct related Coronary artery in acute ST elevation MI.

Article 15: truth or fiction?

Article 15 of the Indian Constitution states that, “The State shall not discriminate against any citizen on grounds only of religion, race, caste, sex, place of birth or any of them; No citizen shall, on grounds only of religion, race, caste, sex, place of birth or any of them, be subject to any disability, liability, restriction or condition with regard to (a) access to shops, public restaurants, hotels, and places of public entertainment or (b) the use of wells, tanks, bathing ghats, roads, and places of public resort maintained wholly or partly out of State funds or dedicated to the use of the general public”

Analogizing Of Metabolic Syndrome In Siddha System Of Medicine-a Literature Review

Background: In worldwide, 20-25% of the population have the Metabolic Syndrome (MetS). The highest prevalence rate reported in South Asia of MetS in the Punjabi community in India by Adult Treatment Panel III criteria. The metabolic syndrome (MetS) is a major and escalating public-health and clinical challenge worldwide in the wake of rapid urbanization, surplus energy intake, increasing obesity, and sedentary life habits. Nowadays, the use of Complementary and Alternative Medicine (CAM) is increasing rapidly due to the inadequate solution for the newly developed health issues. Method: In this study, the International Diabetic Federation (IDF) criteria were used as a standard tool for comparison. A total of 9 sources (4 Siddha classical textbooks, e-data such as pub-med, Google scholar, AYUSH research portal, NAMSTP) were searched to identify the appropriate analog for MetS. Results: 13 Terms related to MetS were identified from the 4 Siddha classical literature, whereas the e-data did not provide any term related to MetS. In those 13 terms, 3 terms which were closely relevant to MetS signs and symptoms were Aiya Migu Kunam, Paci Aiya Noi, and Megam. As a final point, this paper identified the Siddha analog for MetS as Aiyamigukunam. Conclusion: This paper ended up with analog to MetS as Aiyamigukunam and made a comparison with the standard IDF criteria for MetS.

Determination of Macronutrients, Micronutrients and Heavy Metals Present in Spilanthes acmella Hutch and Dalz: Possible Health Effects

The study was conducted for quantitive determination of macronutrients, micronutrients and heavy metals present in Spilanthes acmella Hutch and Dalz, a traditionally used important medicinal plant. The results illustrated the presence of substantial amounts of essential nutrient elements in different parts of the plant. K and Mg were detected in the range between 36.35 ± 1.01 to 67.78 ± 1.33 g/kg and 2.17 ± 0.13 to 7.02 ± 0.84 g/kg of DWS respectively. While the essential micronutrients Fe, Na, Mn, Zn and Cu were detected in the range between 62.62 ± 12.72 to 856.95 ± 76.61 mg/kg, 365.47 ± 23.84 to 633.03 ± 38.12 mg/kg, 51.66 ± 7.77 to 186.33 ± 13.92 mg/kg, 41.87 ± 2.85 to 53.89 ± 3.79 mg/kg and 18.49 ± 2.07 to 48.71 ± 4.89 mg/kg of DWS respectively. Besides, heavy metals (Cd, Ni and Pb) detected in some of the plant samples were beyond the maximum permissible limit (MPL) of FAO/WHO for herbal medicines. The concentrations of the essential nutrient elements except zinc were significantly different in different parts of the plant (p < 0.001). Further variation in the concentrations of the elements in the plant was observed with respect to seasonal changes and geographical conditions. Nevertheless the findings corroborate ethnomedicinal significance of the plant and signify the possibilibity of utilizing its standardized products for preparation of food supplements as well as multidimensional therapeutic herbal medicines.

A retrospective interventional study for evaluation of efficacy and safety of sildenafil citrate in improving intrauterine growth restriction and oligohydramnios using ultrasound Doppler velocimetry

Background: Intrauterine growth restriction (IUGR) is one of the major reasons for neonatal morbidity and mortality. Oligohydramnios is a common finding in IUGR. In majority of these cases diminished utero-placental blood flow is observed. However, in spite of this understanding and identification of high-risk patients, the management options are limited. Sildenafil citrate, a phosphodiesterase type-5 inhibitor improves utero-placental perfusion.Methods: We present a retrospective interventional study involving 50 adult pregnant women diagnosed with early-onset IUGR (n=38) and oligohydramnios (n=12). Vaginal sildenafil citrate 25 mg t.i.d. was started from the day of diagnosis till delivery. Primary efficacy endpoints included changes in Doppler parameters i.e., amniotic fluid index (AFI), uterine artery (UA)- pulsatility index (PI), resistance index (RI) and systolic diastolic ratio (S/D ratio). Secondary endpoints included live birth, birth weight, Apgar score at birth, neonatal survival to hospital discharge and adverse maternal side effects.Results: There was a statistically significant improvement in UA-PI, RI and S/D ratios (p<0.0001) in all cases. In oligohydramnios cases, treatment showed a statistical significant increase in AFI score (2.86±1.33 cm). The mean birth weight on delivery was 2200 gm with good Apgar scores. No major adverse effects were reported by women using sildenafil citrate vaginally.Conclusions: Sildenafil citrate, by increasing utero-placental perfusion, improves uterine artery Doppler patterns, AFI, fetal weight and overall better neonatal survival rates by reducing neonatal morbidity and mortality. Sildenafil citrate may hold a promising treatment strategy for management of IUGR and oligohydramnios.

Evaluation of awareness about obesity among general public visiting the tertiary care hospital

Background: Obesity is one of the fastest growing threats of health and well-being for both developed and developing countries. The aim of the study was to evaluate the awareness about obesity among general public.Methods: After obtaining institutional ethics committee approval and written informed consent from the participants, anthropometric measures like height, weight, hip and waist circumference for computing body mass index and waist hip ratio were taken. Using portable bioelectric impedance analyzer body fat percentage was measured. A validated questionnaire including socio demographic details and questions evaluating the awareness about obesity were given to the participants.Results: Totally 100 participants were evaluated, of which majority being female. Mean height of the male and female participants was 164 and 152cm respectively. Similarly, mean weight was found to be 72 and 65 kg. Based on the body mass index only 19% participants were within normal range, remaining 81% were overweight and obese. Percent body fat and waist hip ratio was found to be increased in both sexes. Majority of the participants were aware that obesity is associated with health problems but most of them were unaware how it is measured and the dietary foods to be taken to reduce obesity. However 64% participants think that obesity can reduce the life expectancy of the individual.Conclusions: Majority of the participants were obese and overweight while awareness about preventive measures was still lacking. Hence health care personnel need to take greater effort to educate and inform people about the implications.

Recurrent abdominal and lower limb venous thrombosis due to inherent protein-C and protein-S deficiency

Protein-C and protein-S deficiency is associated with a hypercoagulable state which usually presents with recurrent venous thrombosis as a common complication. But extensive thrombosis involving all the major abdominal and lower limb veins is quite rare. Here, we report a case of a 27-year-old woman presented with engorged veins all over abdomen and chest since 20 days. Clinical examination revealed signs suggestive of portal venous hypertension with moderate splenomegaly. Protein-C and protein-S levels were found to be low. Portal venous doppler ultrasound and CT-venogram revealed chronic thrombosis of portal vein, inferior vena cava, bilateral iliac and femoral veins with extensive collaterals formation and partial thrombosis in collaterals as well.  The patient was successfully managed with anti-coagulating agent (acenocoumarol) and has been maintained on regular follow-up to avoid reoccurrence of thrombosis.

Prevalence and socio-demographic status on kidney stone patients in Thanjavur district, Tamil Nadu, India

Background: The formations of human kidney stones are affecting large number of peoples in various age groups in worldwide. The deposition of few minerals, crystalline materials in the kidney and urinary bladder are during the process of metabolism. Stone analysis is of great importance to the therapy and metaphylaxis of residual and recurrent stones.Methods: A cross-sectional study carried out among 150 populations in rural/urban field practice area of department of community medicine, Thanjavur Government Medical College, Thanjavur, Tamil Nadu, India. The objectives of the study were to estimate the prevalence of risk factors for kidney stone patients. Data was analyzed using the SPSS version 20.0 software.Results: Among the 150 people were studied in age group of 20–80. Majority (46%) were more than 60 years of age. In this study, the majority of female 56% than men were representing 45% of the sample. It observed that the kidney stone patients were higher in the age group of 21-60 (46%) and lower <20 (1%) and >60 (7%) which was statistically significant (15.33±8.74; p=0.01).Conclusions: The results suggest that calcium oxalate stones are predominant in the selected study area. Kidney stone formation may be due to the food habits (diet), age, sex, obesity, genetics and environmental factors, geographical location, climate and lifestyle. The present investigation aims to assess the status of kidney stone diseases and risk factors in and around Thanjavur and the results have been discussed

Knowledge and attitude on human papilloma virus among adolescent girls in school students at Puducherry

Background: Human papillomavirus (HPV) is one of the most common causes of sexually transmitted infections. About 50–80% of sexually active women are exposed to at least one HPV type during their lifetime.Methods: A descriptive study to assess the knowledge and attitude on human papilloma virus among adolescent girls belonging to selected school at Puducherry. The objectives of the study were to assess the knowledge and attitude regarding HPV among adolescent girls. Adolescent girls were selected on the basis of convenient sampling technique. Structured teaching program were provided for 60 adolescent girls. Questionnaires are given to the students, collected and data were analyzed using the SPSS version 20.0 software.Results: The data will be collected from adolescent girls in the age group of 13-18 years among selected school students. The results found that majority of adolescent girls having inadequate knowledge (56.7%). There are 36.7% of adolescent girls having moderately adequate knowledge and only 6.6% of adolescent girls are having adequate knowledge on HPV.Conclusions: The majority of the girls having poor knowledge and attitude on HPV. The students need to be encouraged to engage in safe sexual practice to prevent and reduce risk of HPV infection. They have suggested that awareness effective and cost effective in improving the knowledge and attitude on human papilloma virus and can be implemented in daily living to have a healthy life.

Determinants of dysphagia following stroke

Background:Swallowing is affected following stroke. Many studies focus on various aspects of swallowing difficulties (dysphagia) following stroke. However, there are not many studies on the determinants of dysphagia following stroke. The aim of the present study is to establish the association between various factors with the severity of dysphagia. Methods: After screening for Mann Assessment of Swallowing Ability (MASA),110 patients, post-stroke were selected using consecutive sampling to assess the common risk factors, namely the presence of diabetes mellitus, dyslipidemia, hypertension, alcohol usage and smoking habits. Additionally, other variables such as age, gender, type of lesion, side of lesion, tobacco chewing, speech disorders, arterial dysfunction, lobe involvement and Brunnstrom's stages, were also evaluated using a structured interview method. 2 (chi-squared) analysis was carried outto find out the association between the selected determinants and severity of dysphagia following stroke.Results: It was found that age and Brunnstrom's stages are the determinants of dysphagia, as analysis showed a strong association with a p value < 0.001. A marginal association between post-stroke dysphagia and type of lesion with a p value of 0.056 was also observed.Conclusions: Among15 factors evaluated, age, type of lesion and Brunnstrom's stages showed a significant association with the severity of dysphagia following stroke. This study advocates early dysphagia management for elderly patients with high Brunnstrom's grading, for those who are not expected to spontaneously recover following stroke, and for earlier and better community rehabilitation

Inter-relationship of behaviour, faecal testosterone levels and glandular volatiles in determination of dominance in male Blackbuck

The social hierarchy of blackbuck plays a crucial role in mate selection and establishment of hierarchy in order to maintain successful reproduction. The factors that influence dominancy have not been yet investigated in the Indian male blackbuck. Here, we investigated the interrelationships between behaviours (aggressive and scent marking), chemical profiles of preorbital gland secretion and faecal testosterone levels in male blackbuck with special reference to dominance hierarchy. The frequency of aggressive behaviour, preorbital gland scent marking behaviour and faecal testosterone level were significantly higher (P <0.001) in the dominant males than the other males. Among the 43 major volatile compounds identified in the pre-orbital gland posting of dominant and subordinate male Blackbucks, four compounds viz., 2-methyl propanoic acid (I), 2-methyl-4-heptanone (II), 2,7-dimethyl-1-octanol (III) and 1,15-pentadecanediol (IV) were present only in the preorbital gland post of the dominant male during the hierarchy period. The results suggest that male blackbuck preorbital gland marking behaviour is meant to defend the home range or territorial region, and the scent odour suppresses aggression, scent marking, scent production and territorial patrolling of subordinate males. The behavioural expression, level of testosterone and volatile chemical profiles are closely interlinked towards establishment of dominance in the blackbuck. This investigation is the first of its kind to detect establishment of dominance hierarchy based on identification of volatile chemical compounds of preorbital gland and assessment of faecal testosterone in blackbuck.

Evaluation of research in India – are we doing it right?

The evaluation of performance in scientific research at any level – whether at the individual, institutional, research council or country level – is not easy. Traditionally, research evaluation at the individual and institutional levels has depended largely on peer opinion, but with the rapid growth of science over the last century and the availability of databases and scientometric techniques, quantitative indicators have gained importance. Both peer review and metrics are subject to flaws, more so in India because of the way they are used. Government agencies, funding bodies and academic and research institutions in India suffer from the impact factor and h-index syndrome. The uninformed use of indicators such as average and cumulative impact factors and the arbitrary criteria stipulated by agencies such as the University Grants Commission, Indian Council of Medical Research and the Medical Council of India for selection and promotion of faculty have made it difficult to distinguish good science from the bad and the indifferent. The exaggerated importance given by these agencies to the number of publications, irrespective of what they report, has led to an ethical crisis in scholarly communication and the reward system in science. These agencies seem to be unconcerned about the proliferation of predatory journals and conferences. After giving examples of the bizarre use of indicators and arbitrary recruitment and evaluation practices in India, we summarise the merits of peer review and quantitative indicators and the evaluation practices followed elsewhere.
