INTRODUCTION The UN General Assembly in September 2021 will bring countries together at a critical time for marshalling collective action to tackle the global environmental crisis. They will meet again at the biodiversity summit in Kunming, China and the climate conference (COP26) in Glasgow, UK. Ahead of these pivotal meetings, we – the editors of health journals worldwide – call for urgent action to keep average global temperature increases below 1.5°C, halt the destruction of nature, and protect health. Health is already being harmed by global temperature increases and the destruction of the natural world, a state of affairs health professionals have been bringing attention to for decades.1 The science is unequivocal; a global increase of 1.5°C above the pre-industrial average and the continued loss of biodiversity risk catastrophic harm to health pulmonary morbidity and mortality.5,6 Harms disproportionately affect the most vulnerable, including among children, older populations, ethnic minorities, poorer communities and those with underlying health problems.2,4 Global heating is also contributing to the decline in global yield potential for major crops, falling by 1.8-5.6% since 1981; this, together with the effects of extreme weather and soil depletion, is hampering efforts to reduce undernutrition.4 Thriving ecosystems are essential to human health, and the widespread destruction of nature, including habitats and species, is eroding water and food security and increasing the chance of pandemics.3,7,8 The consequences of the environmental crisis fall disproportionately on those countries and communities that have contributed least to the problem and are least able to mitigate the harms. Yet no country, no matter how wealthy, can shield itself from these impacts. Allowing the consequences to fall disproportionately on the most vulnerable will breed more conflict, food insecurity, forced displacement and zoonotic disease – with severe implications for all countries and communities. As with the covid-19 pandemic, we are globally as strong as our weakest member. Rises above 1.5°C increase the chance of reaching tipping points in natural systems that could lock the world into an acutely unstable state. This would critically impair our ability to mitigate harms and to prevent catastrophic, runaway environmental change.9,10

A key step in publishing one's manuscript is selecting the journal. If not done right, your work could lose its relevance. There are numerous factors that you may consider in choosing an appropriate journal for your manuscript and these have been listed out in this article. These include journal metrics, reputation, audience, the range and type of articles that the journal covers, turnaround time, its circulation and reach, and the business model of the journal. We, in this article, have covered certain important metrics of a journal like an impact factor, citation index, rejection rate, and the Eigen factor. We have also described the business models that govern scientific publication today – both the traditional and the open-access model – in adequate detail, along with their key advantages and disadvantages. We hope that this article would help you make the key decision of finding the right journal for your manuscript.

Background/Aims Predictors of short-term outcome of intravenous (IV) steroid therapy in acute severe ulcerative colitis (ASUC) have been well described, but the impact of cytomegalovirus (CMV) infection as a predictor of outcome remains debatable. We investigated the role of quantitative CMV polymerase chain reaction (PCR) as a predictor of short-term outcome in patients with ASUC. Methods Consecutive patients with ASUC satisfying Truelove and Witts criteria hospitalized at All India Institute of Medical Sciences (AIIMS) from May 2016 to July 2019 were included; all received IV steroid. The primary outcome measure was steroid-failure defined as the need for rescue therapy (with ciclosporin or infliximab) or colectomy during admission. AIIMS’ index (ulcerative colitis index of severity >6 at day 1+fecal calprotectin >1,000 μg/g at day 3), with quantitative CMV PCR on biopsy samples obtained at initial sigmoidoscopy were correlated with the primary outcome. Results Thirty of 76 patients (39%) failed IV corticosteroids and 12 (16%) underwent surgery. Patients with steroid failure had a significantly higher mucosal CMV DNA than responders (3,454 copies/mg [0–2,700,000] vs. 116 copies/mg [0–27,220]; P2,000 copies/mg (odds ratio [OR], 10.2; 95% confidence interval [CI], 2.6–39.7; P2,000 copies/mg) independently predicts failure of IV corticosteroids and short-term risk of colectomy and it has an additional value to the established markers of disease severity in patients with ASUC.

La publicación de este artículo es una iniciativa organizada por la Alianza Global por el Clima y la Salud (GCHA, por sus siglas en inglés) a través de la Alianza de Salud del Reino Unido sobre el Cambio Climático (UKHACC, por sus siglas en inglés) y los miembros del Grupo de Trabajo Latinoamericano sobre Cambio Climático y Salud. La convocatoria tiene un doble objetivo: que los líderes mundiales acuerden los cambios necesarios para mantener el aumento de la temperatura global por debajo de 1,5°C y que los profesionales de la salud adquieran una mayor relevancia en el debate global sobre la crisis climática y la pérdida de la biodiversidad. La convocatoria se desarrolla en el contexto de la próxima celebración de la Asamblea General de Naciones Unidas que se iniciará el 14 de septiembre de 2021, así como también de la celebración de la conferencia climática COP26 que este año se realizará en Glasgow. Este artículo, cuya autoría pertenece principalmente a editores de 18 prestigiosas revistas científicas ampliamente representativas de los continentes y disciplinas de la salud del mundo, ya ha sido publicada simultáneamente en más de 200 revistas científicas internacionales (https://www.bmj.com/content/full-list-authors-and-signatories-climate-emergency-editorial-september-2021). En esta ocasión, la Revista Argentina de Salud Pública se suma a esta iniciativa conjunta a través de la publicación del artículo en español, con el fin de promover su difusión en los países de la Región. El editorial expresa también la necesidad de restablecer la diversidad biológica y proteger la salud, y de que los países de altos ingresos hagan mayores recortes en sus emisiones de carbono y transfieran fondos a los países de ingresos bajos y medianos. Además, exhorta a la intervención de los gobiernos en el rediseño de los sistemas de transporte, las ciudades, la producción y distribución de alimentos, los mercados para las inversiones financieras, los sistemas de salud, entre otros aspectos, lo que redundaría en amplios beneficios para la salud.

Background/Aims Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn’s disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India. Methods This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn’s Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response. Results Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2–6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260–320] vs. 240 [180–280], P=0.001) and 8 weeks (baseline 290 [260–320] vs. 186 [160–240], P=0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P=0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P=0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002–1.017; P=0.046) predicted response to EEN. Conclusions EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.

Abstract Background Unlike perianal fistula, long‐term outcomes of nonperianal fistulae (NPF) in Crohn's disease (CD) are not clear. We aimed to compare the outcomes of medical and surgical therapies in patients with NPF. Methods We retrospectively analyzed the records of patients of CD with NPF who were prospectively followed from January 2005 to December 2018. Results Of the 53 patients with NPF [mean age at presentation:29 ± 14 years; 54.7% male; median duration of follow‐up: 47 months (interquartile range [IQR]:26–76 months)], enteroenteric fistula (37.8%) was the most common presentation. Of 22 patients treated with anti‐tumor necrosis factor (TNF) therapy, complete response was achieved in 40.9% (n = 9). Overall probability of maintaining response was similar between the anti‐TNF and surgical groups (95.2% vs 82.4%; 71% vs 76%; and 63% vs 69%% [P = 0.8] at 1, 2, and 3 years, respectively), with only 13.6% of patients treated with biologicals requiring surgery over 56 months. Twenty‐one patients required upfront surgery (small bowel or ileocolonic resection with/without diversion; 28.5% emergent), with 47.6% postoperative recurrence over 36 months, of which nine patients required biologicals (77.7% response to anti‐TNF therapy). Long‐term outcome was comparable between medically and surgically treated patients; 6.4% developed tuberculosis on anti‐TNF therapy. Two patients (3.7%) developed malignancy (one ‐ enteroenteric, one ‐ colovesical). Conclusion Anti‐TNF therapy appears to be as effective as surgery in this retrospective analysis of patients with NPFCD, and it may be indicated in the absence of abscess and other complications. These patients are at higher risk of fistula‐associated malignancy, which requires a lower threshold for suspicion, especially over the long term in the presence of nonresponse to medical therapy.

The Medical Council of India (MCI) must be commended for its efforts to introduce definitive criteria for appointments and promotions for teachers in medical institutions. On June 8, 2017, the MCI issued a circular[1] to amend the Minimum Qualifications for Teachers in Medical Institutions Regulations, 1998 (henceforth Regulations, 1998).[2] The amendment clarifies the minimum qualifications required for various postgraduate teaching positions in medical colleges. It indicates MCI’s sustained engagement with qualifications of teachers in medical colleges, with the aim of enhancing the quality of teaching, and thereby, the quality of medical professionals passing out. However, we believe that these efforts continue to be inadequate in addressing the varied issues that face medical education and the educators in India. Some of these issues are: (i) The lack of transparency in the manner in which new medical colleges is approved, (ii) the variation in the proportion of private and public medical colleges across states, (iii) the lack of change and innovation in the undergraduate and postgraduate medical curricula to keep up with changing needs, (iv) the poor uptake of newer teaching-learning methods, (v) the poor quality of teachers in several medical colleges, (vi) methods used to assess teachers during selection and promotions, and (vii) failure to assess the impact of policy changes (such as a recent increase in the number of postgraduate seats) on the quality of medical education and training. In this editorial, we focus on one of these issues, i.e.,the appointment and promotion of teachers in medical colleges. The MCI had on September 3, 2015,[3] stated its requirements with regard to research publications for eligibility for promotion of faculty members in medical colleges. This had been critiqued[4,5] mainly on four counts: Exclusion of publications in “electronic-only” journals from consideration for the assessment of performance, awarding points only to original research articles or papers, awarding points only to the first or second authors, and the choice of indexing services for assessing the quality of a journal. While lauding the MCI’s efforts toward improving the standards for teaching faculty at medical colleges in India, these critiques argued that an ill-informed framework for determining eligibility for promotion is likely be self-defeating and even harmful to the profession.

Background/AimsTruelove and Witts criteria have been used to define acute severe colitis since the 1950s. However, hemoglobin (an additional criterion of the definition) levels in the general population in developing countries are lower than in the population of developed countries. We aimed to determine the relevance of Truelove and Witts criteria in the Indian population.MethodsConsecutive patients with acute severe colitis satisfying the Truelove and Witts criteria, hospitalized at a single center between April 2015 and December 2016 were included. All patients received intravenous corticosteroids and 16 required colectomy. The hemoglobin levels at admission were subsequently excluded from the classification criteria, and the effect this had on the criteria for diagnosis was determined.ResultsOut of 61 patients of acute severe colitis diagnosed according to the original Truelove and Witts criteria, 12 patients (20%) had 1 additional criterion, 33 (54%) had 2 additional criteria and 16 (26%) had 3 or more additional criteria in addition to 6 or more blood stained stools on admission. On excluding hemoglobin as an additional criterion from the Truelove and Witts definition, all patients still met the criteria for acute severe colitis.ConclusionsTruelove and Witts criteria can be used to define acute severe colitis in India, despite lower mean hemoglobin in the native population.

Background/Aims: Patients with small bowel strictures have varied etiologies, including malignancy. Little data are available on the demographic profiles and etiologies of small bowel strictures in patients who undergo surgery because of intestinal obstruction but do not have a definitive pre-operative diagnosis.Methods: Retrospective data were analyzed for all patients operated between January 2000 and October 2014 for small bowel strictures without mass lesions and a definite diagnosis after imaging and endoscopic examinations. Demographic parameters, imaging, endoscopic, and histological data were extracted from the medical records. Univariate and multivariate analyses were conducted to identify factors that could differentiate between intestinal tuberculosis (ITB) and Crohn's disease (CD) and between malignant and benign strictures.Results: Of the 7,425 reviewed medical records, 89 met the inclusion criteria. The most common site of strictures was the proximal small intestine (41.5%). The most common histological diagnoses in patients with small bowel strictures were ITB (26.9%), CD (23.5%), non-specific strictures (20.2%), malignancy (15.5%), ischemia (10.1%), and other complications (3.4%). Patients with malignant strictures were older than patients with benign etiologies (47.6±15.9 years vs. 37.4±16.4 years, P=0.03) and age >50 years had a specificity for malignant etiology of 80%. Only 7.1% of the patients with malignant strictures had more than 1 stricture and 64% had proximally located strictures. Diarrhea was the only factor that predicted the diagnosis of CD 6.5 (95% confidence interval, 1.10–38.25; P=0.038) compared with the diagnosis of ITB.Conclusions: Malignancy was the cause of small bowel strictures in approximately 16% patients, especially among older patients with a single stricture in the proximal location. Empirical therapy should be avoided and the threshold for surgical resection is low in these patients.

Background: Gallbladder carcinoma (GBC) exhibits poor prognosis due to its detection at an advanced stage. Upregulation of lysosomal cysteine proteases cathepsin L (CTSL) and cathepsin B (CTSB) has been implicated in several tumorigenic processes. However, no such information in GBC was available. Therefore, the present study was planned to investigate the expression and clinical significance of these cathepsins in GBC.Methods: Activities of CTSL and CTSB were assayed in the gallbladder (GB) tissues obtained from GBC patients (n = 43) and control subjects (n = 69). Protein and mRNA levels were quantified using immunohistochemistry and real-time PCR (qPCR), respectively. Finally, serum levels of CTSL and CTSB were estimated by ELISA. Receiver operating characteristic (ROC) curve analysis was used for the assessment of sensitivity, specificity, and diagnostic accuracy of these cysteine cathepsins in GBC. The association of combined CTSL and CTSB activity with overall survival was assessed using Kaplan Meier survival analysis.Results: The expression and activity of both CTSL and CTSB were significantly increased (p < 0.050) in tumors of GBC patients as compared to controls. Enzymatic activity of CTSL+B and CTSB exhibited a strong positive association with tumor stage and lymph node involvement in GBC (p < 0.050). Interestingly, the elevated activity of combined CTSL+B was also associated with increased mortality in these patients. Furthermore, significantly enhanced levels of serum CTSL and CTSB were also observed in GBC (p < 0.050) as compared to controls. ROC analysis revealed high diagnostic significance of serum CTSB and CTSL for distinguishing GBC patients from controls with an area under the curve (AUC) of 82 and 77%, respectively.Conclusion: This study, for the first time, demonstrates the clinical significance of CTSL and CTSB overexpression in GBC. Our findings may help improve the clinical management of this carcinoma.

Introduction. Hypersplenism in cirrhosis is not infrequent and may compromise with quality of life and therapy. Splenectomy is a therapeutic option, but information on results of splenectomy is scarce.Material and methods. Consecutive patients with cirrhosis who underwent splenectomy between 2001-2010 were included in the study. Safety, efficacy of splenectomy and subsequent influence on therapy were evaluated.Results. Thirty three patients (mean age 30.9 ± 11.6 years, 19 men, viral 48.5%, autoimmune 15.1%, cryptogenic 36.4%) underwent splenectomy. Twenty were Child's A, 13 Child's B. Twenty patients had > 6 months follow up. Common indications were inability to treat with interferon, transfusion-dependent anemia, recurrent mucosal bleeds, and large spleen compromising quality of life. Median hospital stay was 7 (4-24) days. There was no splenectomy related mortality. Twenty three (70%) patients had post-operative complications, most commonly infections. Two patients required percutaneous drainage of post-operative collections, and 1 needed re-exploration for intra-abdominal bleed. Subsequent to splenectomy platelet count (44,000 to 151,000/mm3, p < 0.01) and TLC (2,500 to 13,400/mm3, p < 0.01) had sustained increase in all patients except one. Five HCV cirrhotics completed interferon and ribavirin therapy, 4 achieved sustained viral response. The quality of life improved and there was no recurrence of infections, mucosal bleed or anemia requiring transfusions in any patient. In patients on long term follow up (median duration 27 months), the median Child's score improved from 6 at baseline to 5 at follow up (p < 0.05).Conclusions. Splenectomy was safe and effective in patients with cirrhosis, and improved therapeutic options as well as Child's score.

Two months after a stab injury to the abdomen, a 35-year-old male presented at the All India Institute of Medical Sciences with haematemesis, shock and portal hypertension. Computed tomography of the abdomen and abdominal angiography revealed a large fistulous communication between an abdominal aortic pseudoaneurysm and a branch of the superior mesenteric vein. The fistula was occluded percutaneously, which allowed the patient to stabilise haemodynamically and, finally, to undergo a definitive surgical excision of the pseudoaneurysm and repair of the aortic defect.

Over 200 health journals call on the United Nations, political leaders, and health professionals to recognise that climate change and biodiversity loss are one indivisible crisis and must be tackled together to preserve health and avoid catastrophe. This overall environmental crisis is now so severe as to be a global health emergency.
