Prevalence and risk factors associated with undiagnosed hypertension among adults aged 15-49 years in India: insights from the National Family Health Survey (NFHS-5).

OBJECTIVES: To estimate the prevalence and identify the factors associated with undiagnosed hypertension in India. STUDY DESIGN: A secondary data analysis using the National Family Health Survey (NFHS-5) covering the period 2019-2021. METHODS: Information on hypertension among individuals aged 15-49 years was extracted from the survey dataset. We estimated the prevalence of undiagnosed hypertension using physical measurements along with self-reported data from the survey. A log-binomial model with survey-adjusted Poisson regression was used to estimate the prevalence ratio between undiagnosed and diagnosed hypertension. Multinomial logistic regression analysis examined the factors associated with diagnosed hypertension (vs healthy) and undiagnosed hypertension (vs healthy). All the analyses were survey-weight adjusted and stratified by gender. RESULTS: The survey-adjusted prevalence of undiagnosed hypertension was 8.75% (8.62%-8.87%) and was higher among males [13.56% (13.03%-14.12%)] than in females [8.14% (8.03%-8.25%)]. The proportion of individuals with undiagnosed hypertension among total hypertension was 44.99% (44.44%-45.55%) and was higher in males [65.94% (64.25%-67.60%)] than in females [42.18% (41.66%-42.71%)]. CONCLUSIONS: Our findings revealed that age, higher body mass index, no access to health care, and having no comorbidities were risk factors for undiagnosed hypertension. One in twelve people had undiagnosed hypertension, and of those with hypertension, one in two were undiagnosed, with males being disproportionately affected. Targeted public health interventions are crucial to improve hypertension screening, particularly among middle-aged and obese individuals without comorbidities.

Mapping and visualizing the research contribution of India on telemedicine: A scientometric study.

Background: The term "Telemedicine" is being used in the medical and health sector to treat patients and to provide medical guidance remotely. The intellectual output from India in terms of publications was harvested from Scopus® with the keyword "Telemedicine" and analyzed by using bibliometric techniques. Methods: The source data was downloaded from the Scopus® database. All the publications on telemedicine and indexed in the database up to the year 2021 were considered for scientometric analysis. The software tools VOSviewer® version 1.6.18 to visualize bibliometric networks, statistical software R Studio® version 3.6.1 with the Bibliometrix package Biblioshiny® were used for analysis and data visualization, and EdrawMind® was used for mind mapping. Result: India contributed 2,391 (4.32%) publications on telemedicine to a total of 55,304 publications worldwide until 2021. There were 886 (37.05%) papers that appeared in open access mode. The analysis revealed that the first paper was published in the year 1995 from India. Steep growth in the number of publications was observed in 2020 with 458 publications. The highest, 54 research publications, appeared in the "Journal of Medical Systems." The All India Institute of Medical Sciences (AIIMS), New Delhi, contributed the highest number of publications (n = 134). A considerable overseas collaboration was observed (USA: 11%; UK: 5.85%). Conclusions: This is the first such attempt to address the intellectual output of India in the emerging medical discipline of telemedicine and has yielded useful information such as leading authors, institutions, their impact, and year-wise topic trends.

Atypical theileriosis with cutaneous involvement in a cow in India: a case report.

Bovine tropical theileriosis caused by Theileria annulata is an overwhelming haemoprotozoan tick-borne disease in taurine and cross-bred cattle in Punjab, India. However, there seems to be no report from India of cutaneous nodules associated with the disease. This report describes a five-year-old cross-bred cow presented to a university clinic with a history of fever, inappetence and malaise for the past six to seven days. Clinical examination revealed normal vital parameters, pale mucous membranes, mild enlargement of the prescapular lymph nodes and multiple subcutaneous nodular masses (2-4 cm) on the neck and abdomen. Haematology revealed mild anaemia and leucopenia with 48% neutrophils, 48% lymphocytes and 4% eosinophils. Romanowsky-stained smears of fineneedle aspiration biopsy samples from swollen lymph nodes and subcutaneous masses showed an increased number of lymphoid cells, suggesting cutaneous lymphomatosis. However, a critical examination of the smears from subcutaneous nodules showed a large number of Koch's blue bodies in macrophages and lymphoblasts, and several piroplasms were also noticed within the red blood cells in lymph node smears. A peripheral blood smear revealed mild to moderate parasitaemia. Extracted DNA from the parasitologically positive blood sample was subjected to nested polymerase chain reaction (nPCR) using T. annulata speciesspecific primers encoding the 30-kiloDalton major sporozoite surface antigen. The desired 572-base pair amplified product of the nPCR was comparable to the positive control. This seems to be a rare case of T. annulata in an adult cross-bred cow, showing cutaneous nodular involvement.

La theilériose bovine tropicale est une maladie causée par le protozoaire Theileria annulata et transmise par les tiques, affectant massivement les populations de bovins et de bovidés métis au Pendjab (Inde). Il semble toutefois que la présence de nodules cutanés associés à la maladie n'y ait jamais été rapportée jusqu'à présent. Les auteurs décrivent le cas soumis à une clinique vétérinaire universitaire d'une vache métisse âgée de cinq ans qui présentait depuis six à sept jours un tableau fébrile accompagné d'une perte d'appétit et d'un affaiblissement général. À l'examen clinique, les paramètres vitaux étaient normaux mais une pâleur des membranes muqueuses a été observée, ainsi qu'un gonflement modéré des ganglions lymphatiques préscapulaires et de nombreuses masses nodulaires sous-cutanées (de 2 à 4 cm d'épaisseur) au niveau du cou et de l'abdomen. L'hématologie a mis en évidence une anémie modérée et une leucopénie, les leucocytes se répartissant en 48 % de neutrophiles, 48 % de lymphocytes et 4 % d'éosinophiles. Les frottis à coloration de Romanowsky d'une biopsie par aspiration à l'aiguille fine des ganglions lymphatiques enflés et des masses sous-cutanées ont fait apparaître une augmentation du nombre de cellules lymphatiques évocatrice d'une lymphomatose cutanée. Néanmoins, un examen critique des prélèvements de nodules sous-cutanés a permis de constater la présence d'un grand nombre de corps bleus de Koch dans les macrophages et les lymphoblastes ; en outre, de nombreux piroplasmes ont été trouvés dans les globules rouges des frottis de ganglions lymphatiques. Un frottis de sang périphérique a permis de quantifier la parasitémie comme étant de niveau faible à modéré. L'ADN extrait de l'échantillon de sang à parasitologie positive a été soumis à une amplification en chaîne par polymérase nichée (nPCR) utilisant des amorces spécifiques de T. annulata codant pour l'antigène majeur de surface (30 kDa) du sporozoïte. Le produit amplifié par nPCR de la séquence souhaitée de 572 paires de bases était similaire à celui de l'échantillon de contrôle positif. Il s'agit probablement d'un cas rare d'infection à T. annulata chez une vache adulte métisse présentant des manifestations nodulaires cutanées.

La teileriosis tropical bovina causada por Theileria annulata es una devastadora enfermedad hemoprotozoaria transmitida por garrapatas que afecta al ganado taurino e híbrido del Punjab (India). Ahora bien, en la India no parece haber ningún caso descrito de esta enfermedad que se acompañe de la presencia de nódulos cutáneos. Los autores describen el caso de una vaca de cinco años híbrida que fue presentado a una clínica universitaria con un cuadro de fiebre, pérdida de apetito y decaimiento en los seis a siete días anteriores. El examen clínico puso de manifiesto parámetros vitales normales, mucosas pálidas, leve hipertrofia de los ganglios linfáticos prescapulares y múltiples bultos subcutáneos de tipo nodular (2 a 4 cm) en cuello y abdomen. El análisis hematológico reveló una leve anemia y leucocitopenia, con un 48% de neutrófilos, un 48% de linfocitos y un 4% de eosinófilos. Tras proceder a una biopsia de ganglios inflamados y bultos subcutáneos por aspiración con aguja fina, el examen de frotis de estas muestras con tinción de Romanowsky reveló un número excesivo de células linfáticas, lo que parece apuntar a una linfomatosis cutánea. No obstante, al examinar más a fondo los frotis de nódulos subcutáneos se observó que macrófagos y linfoblastos albergaban un gran número de cuerpos azules de Koch. También se observaron varios piroplasmas dentro de los eritrocitos presentes en los frotis de ganglios linfáticos. Un frotis de sangre periférica reveló una parasitemia entre leve y moderada. El ADN extraído de esta muestra de sangre positiva fue sometido a una técnica de reacción en cadena de la polimerasa (PCR) anidada en la que se emplearon cebadores específicos de la especie T. annulata que codifican el antígeno de superficie principal de 30 kDa del esporozoíto. La deseada secuencia de 572 pares de bases amplificada por PCR resultó comparable con la correspondiente secuencia de la muestra positiva de control. Parece tratarse pues de un caso raro de infestación por T. annulata de una vaca adulta híbrida que se acompaña de nódulos cutáneos.

Nanoengineering ABO3 active sites from low-energy routes (TX100-stabilised water-in-oil microemulsions, surface segregation and surface complexation on colloidal AlOOH/sol-gel Al2O3 surfaces) for pollution control catalysis.

It is shown that water-in-oil microemulsions (m/e or µE) can produce BaCeO3 (BCO) and LaCoO3 (LCO) precursors. The nanoparticles (NPs) adsorb on AlOOH sols, in much the same way as Turkevich previously immobilised platinum group metal sols. BCO is active in CO and propane oxidation and NO removal under stoichiometric exhaust conditions, but LCO is a better oxidation catalyst. Activity was also seen when Ba,Ce and La,Co are inserted into/segregate at the surface of AlOOH/Al2O3. However, there is only formation of low levels of BCO, CAIO3 (CAO), LCO and LaAIO3 (LAO) perovskites, along with aluminates and separate oxides. The complexing of cations by AlOOH surface-held oxalate ions, albeit with different efficiencies, has also been explored. All three routes yield active catalysts with micro-domains of crystallinity; microemulsions produce the best defined perovskite NPs, but even those from surface segregation have higher turnover numbers than traditional Pt catalysts. Perovskite NPs may open up green chemistry for air pollution control that is consistent with a circular economy.

Biosimilars: what the dermatologist should know.

Biosimilars are highly similar versions of approved branded biologics. In contrast to generics, which are identical copies of the originator medicines, biosimilars are considered unique but related molecules that differ from the originator reference product as well as from each other. Owing to the complexity of biologic medicines, such as therapeutic monoclonal antibodies, minor differences between biosimilars and the reference products are acceptable provided these differences do not result in any clinically meaningful differences in safety or efficacy. In addition, minor changes in structure and function may occur over time in originator biologic products as a result of alterations in production materials (e.g. cell lines), processes or conditions. The developmental process for biosimilars focuses on a 'totality of evidence' approach that emphasizes a stepwise investigational process, including comprehensive structural, functional, pharmacologic and clinical assessment for similarity. The goal of the phase 3 clinical development programme for a biosimilar is not to establish efficacy, per se, but to demonstrate that there are no clinically meaningful differences between the proposed biosimilar and the reference product. The requirement to show clinical similarity informs biosimilar study design, including the selection of the patient population, disease state (indication), study endpoints and statistical methods. Based on the clinical trial results in a representative patient population, results may be extrapolated to other indications provided scientific justification is demonstrated based on, among other things, similar mechanism of action in the extrapolated indications. This review presents the current state of knowledge with respect to biosimilars. We aim to provide the practising clinician with a working knowledge of biosimilars as well as provide some practical guidance on their use and potential benefits in treating dermatologic diseases.

Clinical similarity of the biosimilar ABP 501 compared with adalimumab after single transition: long-term results from a randomized controlled, double-blind, 52-week, phase III trial in patients with moderate-to-severe plaque psoriasis.

BACKGROUND: ABP 501, a U.S.A. Food and Drug Administration- and European Medicines Agency-approved biosimilar, is highly similar to adalimumab in structure, function and pharmacokinetics. OBJECTIVES: To demonstrate similarity in efficacy, safety and immunogenicity of ABP 501 vs. adalimumab for moderate-to-severe plaque psoriasis (clinical trial: NCT01970488). METHODS: Patients were randomized (1 : 1) to receive ABP 501 or adalimumab 40 mg every 2 weeks for 16 weeks. At week 16, patients with ≥ 50% improvement from baseline in Psoriasis Area and Severity Index (PASI) score were eligible to continue to week 52. Patients receiving ABP 501 continued; adalimumab patients were rerandomized (1 : 1) to continue adalimumab or undergo a single transition to ABP 501. Key efficacy assessments included percentage PASI improvement from baseline, PASI responders and mean change in affected body surface area from baseline to weeks 16, 32 and 50. Safety was monitored via adverse events (AEs) and antidrug antibodies (ADAs) were assessed. RESULTS: A total of 308 patients were rerandomized at week 16 (ABP 501/ABP 501, n = 152; adalimumab/adalimumab, n = 79; adalimumab/ABP 501, n = 77). PASI percentage improvements from baseline were similar across groups for weeks 16, 32 and 50 (range: 85·8-88·2%), with no significant differences detected across groups in percentages of PASI 50, 75, 90 and 100 responders. Changes from baseline in percentage body surface area affected were similar across groups and time points. No new safety signals were detected. AEs were balanced between groups. Percentages of patients with binding and neutralizing ADAs were similar across treatments. CONCLUSIONS: ABP 501 and adalimumab have similar clinical efficacy, safety and immunogenicity profiles over 52 weeks, including after single transition, in this patient population.

Periurban outbreaks of bovine calf scours in Northern India caused by Cryptosporidium in association with other enteropathogens.

Bovine calf scours reported to be caused by multiple aetiologies resulting in heavy mortality in unweaned calves and huge economic loss to the dairy farmers. Among these, cryptosporidiosis is an emerging waterborne zoonoses and one of the important causes of neonatal calf diarrhoea. Poor immune response coupled with primary cryptosporidial infections predispose neonatal calves to multiple secondary infections resulting in their deaths. In the present study, faecal samples from 100 diarrhoeic calves randomly picked up out of 17 outbreaks of bovine calf diarrhoea in periurban Ludhiana, Punjab in Northern India were subjected to conventional (microscopy, modified Zeihl-Neelsen (mZN) staining) and immunological and molecular techniques (faecal antigen capture ELISA and PCR) for detection of primary Cryptosporidium parvum infection as well as other frequently reported concurrent pathogens, viz. rotavirus and coronavirus, Salmonella spp., Escherichia coli, Clostridium perfringens and Eimeria spp. The faecal antigen capture ELISA and PCR revealed 35% prevalence of C. parvum in contrast to 25% by mZN staining with a relatively higher prevalence (66·7%) in younger (8-14-day-old) calves. The detection rate of the other enteropathogens associated with C. parvum was 45·71% for C. perfringens followed by Salmonella spp (40·0%), rotavirus (36·0%), coronavirus (16·0%), E. coli (12·0%) and Eimeria spp (4·0%) The sensitivity for detection of C. parvum by ELISA and mZN staining in comparison to PCR was 97·14% and 72·72%, respectively. An important finding of the study was that C. parvum alone was found in only 10% of the diarrhoeic faecal samples, whereas, majority of the samples (90%) showed mixed infections ranging from a combination of two to five agents. This is the first documentary proof of C. parvum and associated pathogens responsible for severe periurban outbreaks of bovine calf diarrhoea culminating in heavy mortality from Northern India.

Identification of cyclic lipopeptides produced by Bacillus vallismortis R2 and their antifungal activity against Alternaria alternata.

AIM: To identify the different antifungal biomolecules produced by isolate Bacillus vallismortis R2 and analyse their effect on Alternaria alternata, a common pathogen causing black point disease of wheat. METHODS AND RESULTS: The different antifungal molecules produced by isolate R2 were purified by column chromatography. The liquid chromatography-mass spectrometry of purified fractions confirmed the ability of R2 to produce biomolecules putatively similar to three different families of cyclic lipopeptides (CLPs) viz. surfactins, iturins and fengycins. The synergistic interaction among CLPs was evident from significant increase in the antifungal activity of mixture of purified fractions as compared to that of the individual fractions by agar well diffusion assay. The evaluation of antifungal activity of purified fractions by 96-well microtitre plate assay showed that the fengycin-like molecules supported significantly higher antifungal activity against A. alternata than iturin A and no antifungal activity was supported by surfactin. CONCLUSIONS: The isolate R2, producing different CLPs, can be used as an environmental friendly alternative to chemical fungicides. Among the three different CLPs viz. surfactin, iturin A and fengycin produced by R2, the fengycins were the most active lipopeptides. SIGNIFICANCE AND IMPACT OF THE STUDY: This is the first report on co-production of three different types of CLPs by the cells of B. vallismortis.

Comparative seroprevalence and risk factor analysis of Trypanosoma evansi infection in equines from different agro-climatic zones of Punjab (India).

As parasitaemia is low and fluctuating during the chronic stage of infection, accurate detection of Trypanosoma evansi in blood is difficult. The primary aims of this investigation were to assess for the first time the seroprevalence of T. evansi in all agro-climatic zones of Punjab, by indirect enzyme-linked immunosorbent assay (iELISA) and card agglutination test (CATT/T. evansi), and to evaluate the risk factors associated with latent trypanosomosis. A total of 319 equine serum samples collected from 12 districts of Punjab (India) belonging to different agro-climatic zones revealed 39 (12.23%) and 9 (2.82%) samples to be positive by CATT/T. evansi and iELISA, respectively. The highest prevalence was recorded from the Ludhiana district (42.86% and 7.14% by CATT/T. evansi and iELISA, respectively) in the central plain zone (for which the overall prevalence was 15% and 4.17%, respectively). There was fair agreement between the tests for the detection of T. evansi (kappa = 0.345). Species was the most influential risk factor for infection, with odds ratios (ORs) of 2.81 and 5.63 for donkeys/ mules, in comparison with horses, by CATT/T. evansi and iELISA, respectively. The female equine population (OR = 3.13, 95% confidence interval [CI] = 1.32-7.67 [CATT]) was found to be at a higher risk of seropositivity for T. evansi, particularly on 'unorganised' (inappropriately managed) farms (OR = 3.18, 95% CI = 1.53- 6.65 [CATT]) and among animals used for commercial purposes (OR = 2.51, 95% CI = 1.20-5.21 [CATT]). In conclusion, to declare disease-free status, use of the iELISA followed by retesting of suspect samples by CATT/T. evansi is suggested.

La détection minutieuse de Trypanosoma evansi dans le sang est difficile en raison du nombre faible et fluctuant de parasites pendant la phase chronique de l'infection. L'étude présentée par les auteurs vise, d'une part, à réaliser une première évaluation de la prévalence sérologique de T. evansi dans chacune des zones agro-climatiques du Pendjab en utilisant une épreuve immuno-enzymatique (ELISA) indirecte et le test d'agglutination sur carte pour la trypanosomose (CATT/T. evansi) et, d'autre part, à évaluer les facteurs de risque associés à une présence inapparente de la trypanosomose. Au total, sur les 319 sérums d'équidés prélevés dans 12 districts du Pendjab (Inde) appartenant à des zones agro-climatiques différentes, 39 échantillons (12,23 %) ont donné des résultats positifs avec le CATT/T. evansi et 9 échantillons (2,82 %) ont donné des résultats positifs à l'ELISA indirecte. La prévalence la plus élevée a été enregistrée dans le district de Ludhiana (42,86 % de résultats positifs avec le CATT/T. evansi et 7,14 % de résultats positifs avec l'ELISA indirecte) dans la zone des plaines centrales (où la prévalence globale s'élevait, suivant les méthodes de test, à 15 % et 4,17 %, respectivement). La détection de T. evansi par les deux tests a été concordante (kappa = 0,345). Le facteur de risque ayant le plus d'influence sur la probabilité d'infection était l'espèce, ce risque étant plus élevé chez les ânes et les mulets que chez les chevaux (rapport de cotes [odds ratio, OR] de 2,81 [CATT/T. evansi] et de 5,63 [ELISA indirecte]). Les femelles présentaient également un risque plus élevé de posséder des anticorps anti-T. evansi que les mâles (OR = 3,13 ; intervalle de confiance [IC] à 95 % : 1,32­7,67 [CATT]), en particulier dans les élevages « informels ¼ (sans gestion sanitaire) (OR = 3,18 ; IC à 95 % : 1,53­6,65 [CATT]) ainsi que parmi les animaux utilisés à des fins commerciales (OR = 2,51 ; IC à 95 % : 1,20­5,21 [CATT]). En conclusion, pour la démonstration de l'absence d'anticorps, les auteurs recommandent d'utiliser l'ELISA indirecte puis de soumettre les échantillons douteux à un test de confirmation au moyen du CATT/T. evansi.

La detección precisa de Trypanosoma evansi en la sangre resulta difícil porque en la fase crónica de la infección la parasitemia es baja y fluctuante. Los autores describen una investigación encaminada principalmente a determinar por primera vez la seroprevalencia de T. evansi en todas las zonas agroclimáticas del Punjab por ensayo inmunoenzimático indirecto (ELISAi) y por aglutinación en placa, así como los factores de riesgo asociados a la tripanosomosis latente. De un total de 319 muestras de suero equino procedentes de 12 distritos del Punjab (India) situados en diferentes zonas agroclimáticas, la aglutinación en placa deparó resultado positivo en 39 de ellas (un 12,23%) y el ELISAi en 9 (2,82%). El máximo nivel de prevalencia se registró en el distrito de Ludhiana (42,86% y 7,14% por aglutinación en placa y ELISAi, respectivamente), sito en la zona de la planicie central (que en conjunto deparó una prevalencia del 15% y el 4,17%, respectivamente). Ambas pruebas resultaron bastante coincidentes por lo que respecta a la detección de T. evansi (coeficiente kappa = 0,345). El factor de riesgo más influyente resultó ser la especie: en comparación con los caballos, los asnos o mulas presentaban una razón de probabilidad (RP) de 2,81 y 5,63 para la aglutinación en placa y el ELISAi respectivamente. Se observó que la población de yeguas (RP = 3,13; intervalo de confianza [IC] al 95% = 1,32­7,67 [aglutinación en placa]) presentaba un riesgo más elevado de seropositividad para T. evansi, especialmente en explotaciones «desorganizadas¼ (mal gestionadas) (RP = 3,18; IC 95% = 1,53­6,65 [aglutinación en placa]) y entre los animales utilizados con fines comerciales (RP = 2,51; IC 95% = 1,20­5,21 [aglutinación en placa]). Los autores concluyen proponiendo que, a los efectos de declarar la ausencia de enfermedad, se utilice en primer lugar el ELISAi, seguido de la prueba de aglutinación en placa para las muestras sospechosas.

AMG 151 (ARRY-403), a novel glucokinase activator, decreases fasting and postprandial glycaemia in patients with type 2 diabetes.

Phase I studies have shown that AMG 151 activates glucokinase, a key enzyme in glucose homeostasis. The present randomized, placebo-controlled phase IIa study evaluated the dose-effect relationship of the glucokinase activator AMG 151 relative to placebo on fasting plasma glucose (FPG) in 236 patients (33-35 patients per arm) with type 2 diabetes treated with metformin. Patients received oral AMG 151 at 50, 100 or 200 mg twice daily, AMG 151 at 100, 200 or 400 mg once daily or matching placebo for 28 days. A significant linear dose-effect trend was observed with the twice-daily regimen (p = 0.004) for change in FPG to day 28. No trend was observed with the once-daily regimen. A higher incidence of hypoglycaemia and hypertriglyceridaemia was observed with AMG 151 administration. AMG 151 significantly reduced FPG when administered twice daily but not when administered once daily in patients with type 2 diabetes treated with metformin.

Bactericidal activity and mechanism of action of AZD5847, a novel oxazolidinone for treatment of tuberculosis.

Treatment of tuberculosis (TB) is impaired by the long duration and complexity of therapy and the rising incidence of drug resistance. There is an urgent need for new agents with improved efficacy, safety, and compatibility with combination chemotherapies. Oxazolidinones offer a potential new class of TB drugs, and linezolid-the only currently approved oxazolidinone-has proven highly effective against extensively drug-resistant (XDR) TB in experimental trials. However, widespread use of linezolid is prohibited by its significant toxicities. AZD5847, a novel oxazolidinone, demonstrates improved in vitro bactericidal activity against both extracellular and intracellular M. tuberculosis compared to that of linezolid. Killing kinetics in broth media and in macrophages indicate that the rate and extent of kill obtained with AZD5847 are superior to those obtained with linezolid. Moreover, the efficacy of AZD5847 was additive when tested along with a variety of conventional TB agents, indicating that AZD5847 may function well in combination therapies. AZD5847 appears to function similarly to linezolid through impairment of the mycobacterial 50S ribosomal subunit. Future studies should be undertaken to further characterize the pharmacodynamics and pharmacokinetics of AZD5847 in both in vitro and animal models as well is in human clinical trials.

Accuracy of multidetector CT in detecting anastomotic leaks following stapled left-sided colonic anastomosis.

AIMS: To assess accuracy of multidetector computed tomography (MDCT) and individual radiological signs in the diagnosis of anastomotic leaks. MATERIALS AND METHODS: Patients undergoing anterior resection with a stapled anastomosis over a 2 year period were identified. Electronic and clinical records of these patients were reviewed. Unenhanced and/or enhanced MDCT was performed with intravenous and/or per-rectal contrast medium and read by a radiologist blinded to the patients' clinical details to determine the sensitivity and specificity of specific findings at MDCT for identifying leaks. RESULTS: Seventeen percent (30/170) of the anterior resections were suspected to have an anastomotic leak. Ninety-three percent (28/30) of patients underwent MDCT. Seven point six percent (11+2/170) had a confirmed leak. Two patients underwent surgery without MDCT. A leak was confirmed by MDCT in 91% (10/11) of patients. The sensitivity, specificity, and positive and negative predictive values of MDCT in diagnosing a leak was 0.91, 1, 1, and 0.95, respectively. The sensitivity of peri-anastomotic air, peri-anastomotic collection, extravasation of rectal contrast medium, and staple line integrity was 0.81, 0.63, 0.54, and 0.72, respectively. Use of rectal contrast medium (8/11 cases) increased the subjective ease of diagnosis and was the only sign in one patient. CONCLUSIONS: Presence of peri-anastomotic air is a reliable marker of anastomotic leaks at MDCT. Leakage of rectal contrast medium is highly accurate and increases confidence of diagnosis. The appearance of the staple line itself is not accurate in assessing anastomotic integrity.

Involvement of the family members in caring of patients an acute care setting.

BACKGROUND: Family members are critical partners in the plan of care for patients both in the hospital and at home. Involving the members of the family in acute care can help the nursing staff in emergency. The present study was aimed to find out the role of the family members while caring for the patients admitted in emergency unit of a tertiary care hospital. MATERIALS AND METHODS: A total of 400 family members of the patients were conveniently selected. Only one member per family was interviewed and their role in taking care of the patient in acute care setting was evaluated. RESULTS: The mean age of patients admitted in acute care setting was 46.6 yrs ± 18.8 with the age range of 18-84 years. Majority (39%) of the patients were in the age group of 31-60 years. More than half of the caregivers of patients were males and 88% of them were first-degree relatives. The major tasks performed by the caregivers during the patient care was communicating with doctors/ nursing staff (98%), cleaning and dressing the patient (94%), feeding the patient (90%), procuring medication and other supplies (88%), administering oral medications (74%), changing position and helping for back care (65%), shifting the patients for investigations (60%), collecting reports (35%) and providing physiotherapy (25%). CONCLUSIONS: The results of the study concluded that family involvement in acute care setting can help the nursing staff in taking care of the patient in acute care setting and it also provides the opportunity for preparing them for after care of the patients at home following discharge.

Persistent arthralgia among Chikungunya patients and associated risk factors in Chennai, South India.

CONTEXT: Chikungunya (CHIK) fever is viral disease characterized by joint pain for prolonged duration in various settings. However, there are no reports of long-term follow-up of the CHIK patients from India. AIMS: We conducted a cohort study to describe the clinical manifestations, incidence of persistent arthralgia, and the associated risk factors among patients with CHIK identified during an outbreak in a suburb of Chennai, India. MATERIALS AND METHODS: We conducted a retrospective cum prospective cohort study in Gowripet, Avadi, Chennai. We included all adult CHIK case patients identified during the outbreak. We conducted a nested case-control study to identify the risk factors for persistent arthralgia defined as a CHIK case experiencing arthralgia for more than 15 days from the date of onset of illness. We included all 81 patients and 81 randomly selected controls. RESULTS: All 403 case patients had joint pain. Approximately 40% suffered joint pain for up to 1 month and 7% had it beyond 1 year. The most commonly affected types of joints were knee (96%), wrist (80%), and ankle (77%) joints. Regarding the number of types of joints affected, 36% had six types of joints, 23% had five types of joints, and 14% had three types of joints affected. The overall incidence of persistent arthralgia was 80%. High-grade fever, involvement of four or more types of joints, and joint swelling were significantly associated with persistent arthralgia. CONCLUSIONS: High prevalence of persistent arthralgia indicates the need for appropriate treatment strategies to reduce the severity and duration of joint pain.

Treatment Behaviour of Leprosy Patients on Time Scale.

Leprosy is not a disease of modern civilization and industrialization, but its origin is as old as 4600 BC. Although the cure of leprosy is possible by MDT, there are certain misbelieves in the mind of leprosy patients leads to delay in disease reporting. Wandering of the patient from one healer to another healer also one of the cause that delays the start of MDT. It is known fact that the delayed response in getting medical treatment for leprosy causes permanent physical deformities in the patient. This study is aimed to identify the treatment behavior of leprosy patients on time scale. A total of 251 study subjects were selected randomly attending the Skin & VD OPD of S S Hospital of IMS, BHU, Varanasi. Questions related to treatment behavior on time scale were administered to leprosy patients aged 15 years or above by the interviewer himself. Time gap to start the initial treatment was significantly less in MB cases (5.3 months) as compared to PB cases (7.2 months). MB cases wasted significantly more time with allopathic treatment other than MDT. Urban patients (1.3 months) wasted more time with homeopathy than the rural patients (0.9 months). More than half the cases (51.4%) went for the treatment within three months of noticing symptoms of leprosy. There is a considerable delay in starting the MDT after noticing the first symptom of leprosy. As early as possible, measures to start the proper treatment i.e. MDT should be taken to avoid permanent disability due to leprosy.

Development of a Artificial Intelligence Dental Anxiety Scale (AI -CDAS) For Children: Validation And Reliability.

Assessing children's pain using patient-based pain scales can be challenging. Hence, there is a need of new version Artificial Intelligence Child Dental Anxiety Scale (AI-CDAS) to scale and test its psychometric properties (validity and reliability). This study was conducted to evaluate the validity and reliability of Artificial Intelligence version of the Child Dental Anxiety Scale (AI-CDAS) for anxiety detection scale in children using face as a response set from October 2022 to December 2023. Aim of this study was to examine the reliability and validity of Artificial Intelligence based Child Dental Anxiety Scale (AI-CDAS) using a wide range of age samples in dental clinics. A total of 100 outpatients (Age 03-09 years) from Bharati Vidyapeeth Deemed to be University Dental College and Hospital, Pune, India participated in this study. Dental anxiety was assessed using the Artificial Intelligence Child Dental Anxiety Scale (AI-CDAS) and comparing with a valid and reliable scale of Colored Version of Modified Facial Affective Scale. Reliability and validity was good and significant correlations were found between the AI-CDAS and the Colored Version of Modified Facial Affective Scale. This study suggests that the Artificial Intelligence based Child Dental Anxiety Scale (AI-CDAS) is a valid and reliable measure for assessing children's dental anxiety and may help encourage dentists to formally assess dental anxiety scale in day to day practice. Self-report measures are commonly employed in dental anxiety assessments. One advantage of self report measures is the ease of administration, taking relatively short period of time to complete. They can also assess the reaction to different aspects of the dental experience.

Is Brucella excreted in cattle faeces? - Evidence from Punjab, India.

Brucellosis is a neglected zoonosis that affects animals and people in much of the underdeveloped world. The disease is endemic in cattle in Punjab, India and controlling it is a public health challenge. Dairy farmers and farm labour commonly handle cattle faeces with bare hands and personal protective equipments are not used. No studies have been conducted about the shedding of Brucella species in faeces of sero positive cattle in the state. This study aimed to isolate and identify the Brucella species from faeces of sero positive cattle in Punjab, India. Faecal samples were collected from 350 Brucella sero positive cattle in Ludhiana district of Punjab, India. Isolation was performed using a pre-enriched Brucella selective broth medium as well as Brucella selective medium agar plates containing horse serum and Brucella selective supplements. Isolates were identified using Gram staining technique and rapid slide agglutination test, and then confirmed by using bcsp31 and 16s rRNA genus specific PCR. Isolates were further identified up to species level by using Bruce-Ladder multiplex PCR. Fourteen Brucella species were isolated, all of which showed coccobacilli on gram staining, positive rapid slide agglutination test and amplification of bcsp31 and 16s rRNA genes. Of the 14 isolates, 11 were identified as Brucella abortus and 3 were identified as Brucella melitensis. The study demonstrates that animal faeces could pose a potential risk for animal and human health and faeces of seropositive cattle must be handled with care.

Comparison of efficacy of ultrasound-guided platelet rich plasma injection versus dry needling in lateral epicondylitis-a randomised controlled trial.

PURPOSE: To assess whether Ultrasound guided dry needling is adequate for both common extensor tendon tears and tendinosis or whether ultrasound guided platelet rich plasma (PRP) has a superior outcome when compared to dry needling when there are tears of the common extensor tendon. MATERIALS AND METHODS: This is a single-centre, single-blinded, randomised controlled trial conducted between November 2018 and April 2020. 40 patients diagnosed with lateral epicondylitis based on clinical and sonographic features and having comparable baseline characteristics were randomly assigned to the two study groups (dry needling and PRP). Inclusion criteria were patients aged 20 years or more who were symptomatic for at least 3 months with sonographic evidence of lateral epicondylitis. Exclusion criteria were complete tear of common extensor tendon confirmed on ultrasound and presence of other associated diseases like osteoarthritis of shoulder and elbow. RESULTS: There was significant improvement in the visual analogue scale pain score in PRP group compared to the dry needling group at 9 months. However, this difference was not evident at 3 and 6 months follow-up. Mean improvement in common extensor tendon thickness in PRP group (5.1 mm at 3 months and 4.3 mm at 6 months) was slightly better than dry needling (4.4 mm at 3 months and 4.0 mm at 6 months). There was no difference in tear (if present) healing between both groups at 3 months. However at 6 months follow up, PRP demonstrated significant (mean-2.5) healing in tear compared to dry needling (mean-3.1). CONCLUSION: Two injections of Ultrasound guided PRP are more beneficial non operative treatment compared to ultrasound guided dry needling, in lateral epicondylitis.

GIBPS technique-a novel sequential technique of performing shoulder corticosteroid injections.

The introduction of the xxxxxxxx (GIBPS) technique represents a patient-centric novel and innovative method of ultrasound guided corticosteroid injection targeting the Glenohumeral joint (GHJ) and the Subacromial-Subdeltoid (SASD) bursa in a sequential manner, in the same setting. By integrating the two different sites of injection into a single technique, the procedure has the potential of transforming musculoskeletal interventional radiology and maximising patient care in shoulder pathologies. This procedure aims to reduce patient discomfort, optimise procedural efficiency, and enhance treatment precision through ultrasound guidance and improve the overall patient experience.

Prevalence and risk factor investigation for exposure to Brucella species in surrogate stray cattle population reared in cow shelters in Punjab, India.

Bovine brucellosis is endemic in cattle in India, however not much is known on the prevalence of this disease in stray cattle populations of the country. This study aimed to estimate the prevalence and identify risk factors associated with brucellosis in the stray cattle populations reared in cow shelters (gaushalas) of Punjab, India. Blood samples were collected from 587 cattle reared in 23 cow shelters in 23 districts (one per district) of the Punjab and were tested using Rose Bengal plate test (RBPT), standard tube agglutination test (STAT) and Indirect Enzyme Linked Immunosorbent Assay (i-ELISA). Information on the sex and breed of the animal, total cattle population and presence of a separate shed for parturition were collected. An animal was considered exposed to Brucella infection based on a positive RBPT or STAT test and a positive i-ELISA test. Explanatory variables for the animal level disease status outcome variable were sex and breed of the animal and at the shelter level were shelter cattle population size and presence of a separate shed for parturition. Univariable binomial exact logistic regression analysis was conducted to assess the association of each explanatory variable with the binary outcome variable. Sixty-two animals were seropositive on RBPT, with an apparent seroprevalence of 10.56% (95% confidence interval [CI]: 8.33%, 13.31%) and the estimated true seroprevalence of 11.48% (95% CI: 8.9%, 14.64%). Sixty three animals were seropositive using STAT [apparent seroprevalence of 10.73% (95% CI: 8.48%, 13.50%) and the estimated true seroprevalence of 10.69% (95% CI: 8.27%, 13.67%)], and 68 using i-ELISA [an apparent seroprevalence of 11.58% (95% CI: 9.24%, 14.43%) and the estimated true seroprevalence of 13.28% (95% CI: 10.50%, 16.66%)]. Cross bred cattle had a lower risk of being test positive (odds ratio 0.16, p = 0.04) as compared to indigenous cattle. Due to a ban on cow slaughter in the country, roaming stray cattle infected with brucellosis present a permanent risk of introduction of disease to the dairy farms and other vulnerable populations.
