Epidemiological and Clinical Characteristics of Scorpion Stings in Ahwaz, Southwest Iran (2006-2010)

Background: Scorpion sting is a health problem in the world including tropical regions of Iran as in rural region of Khuzestan province. Therefore appropriate diagnosis and treatment has a special aspect. The aim of present study was to evaluation of demographic status and clinical aspect of scorpion sting patient due to better prevention and treatment and diagnosis.Methods: This survey done by analyzing medical records of patients suffered from scorpion sting, hospitalize in Razi hospital in Khuzestan province (southwest of Iran) among 2006-2010. Patient information have been extracted and inserted in the inquiry form and data were analyzed by SPSS software.Results: In the present study 1922 patients have been studied. Proportion of females stung by scorpion to male was 1.29 to 1. Place of sting were mostly trunk (693 cases =36.05%) and remains were on other part of body. About 419 persons (21.8 %) have come to hospital about 6-24 hours after being stung and 708 people (36.83 %) came there in less than 6 hours. Most sting (41.2 %) were at night time and other were at daylight. 1308 persons were stung by an unknown black and yellow scorpion and 614 cases (31.94%) by scorpion known as Hemiscorpius lepturus. 708 persons of patients (39.83%) have been suffered from hemoglobinoria , 709 persons (39.88%) were suffered from coagulation dysfunction. Totally 508 persons of patients (26.43%) received blood products. 36 of patients were died, of which 24 cases (1.24%) were female and 12 patients (0.62%) were male. most of patients (1842 cases  95.83%) were hospitalized 1-2 days.Conclusion: In this survey, Patients at the emergency units showed signs of local and systemic effects, 36 patients were died. We propose that public awareness and physician readiness combined with the availability of effective antivenom has potential value in reducing complications and lethality in scorpion envenomation

Prevalence and Diversity of Avian Hematozoan Parasites in Asia: A Regional Study

Tissue samples from 699 birds from three regions of Asia (Myanmar, India, and South Korea) were screened for evidence of infection by avian parasites in the genera Plasmodium and Haemoproteus. Samples were collected from November 1994 to October 2004. We identified 241 infected birds (34.0%). Base-on-sequence data for the cytochrome b gene from 221 positive samples, 34 distinct lineages of Plasmodium, and 41 of Haemoproteus were detected. Parasite diversity was highest in Myanmar followed by India and South Korea. Parasite prevalence differed among regions but not among host families. There were four lineages of Plasmodium and one of Haemoproteus shared between Myanmar and India and only one lineage of Plasmodium shared between Myanmar and South Korea. No lineages were shared between India and South Korea, although an equal number of distinct lineages were recovered from each region. Migratory birds in South Korea and India originate from two different migratory flyways; therefore cross-transmission of parasite lineages may be less likely. India and Myanmar shared more host species and habitat types compared to South Korea. Comparison between low-elevation habitat in India and Myanmar showed a difference in prevalence of haematozoans

Global, regional, and national burden of diabetes from 1990 to 2021, with projections of prevalence to 2050: a systematic analysis for the Global Burden of Disease Study 2021

Background Diabetes is one of the leading causes of death and disability worldwide, and affects people regardless of country, age group, or sex. Using the most recent evidentiary and analytical framework from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD), we produced location-specific, age-specific, and sex-specific estimates of diabetes prevalence and burden from 1990 to 2021, the proportion of type 1 and type 2 diabetes in 2021, the proportion of the type 2 diabetes burden attributable to selected risk factors, and projections of diabetes prevalence through 2050. Methods Estimates of diabetes prevalence and burden were computed in 204 countries and territories, across 25 age groups, for males and females separately and combined; these estimates comprised lost years of healthy life, measured in disability-adjusted life-years (DALYs; defined as the sum of years of life lost [YLLs] and years lived with disability [YLDs]). We used the Cause of Death Ensemble model (CODEm) approach to estimate deaths due to diabetes, incorporating 25 666 location-years of data from vital registration and verbal autopsy reports in separate total (including both type 1 and type 2 diabetes) and type-specific models. Other forms of diabetes, including gestational and monogenic diabetes, were not explicitly modelled. Total and type 1 diabetes prevalence was estimated by use of a Bayesian meta-regression modelling tool, DisMod-MR 2.1, to analyse 1527 location-years of data from the scientific literature, survey microdata, and insurance claims; type 2 diabetes estimates were computed by subtracting type 1 diabetes from total estimates. Mortality and prevalence estimates, along with standard life expectancy and disability weights, were used to calculate YLLs, YLDs, and DALYs. When appropriate, we extrapolated estimates to a hypothetical population with a standardised age structure to allow comparison in populations with different age structures. We used the comparative risk assessment framework to estimate the risk-attributable type 2 diabetes burden for 16 risk factors falling under risk categories including environmental and occupational factors, tobacco use, high alcohol use, high body-mass index (BMI), dietary factors, and low physical activity. Using a regression framework, we forecast type 1 and type 2 diabetes prevalence through 2050 with Socio-demographic Index (SDI) and high BMI as predictors, respectively. Findings In 2021, there were 529 million (95% uncertainty interval [UI] 500–564) people living with diabetes worldwide, and the global age-standardised total diabetes prevalence was 6·1% (5·8–6·5). At the super-region level, the highest age-standardised rates were observed in north Africa and the Middle East (9·3% [8·7–9·9]) and, at the regional level, in Oceania (12·3% [11·5–13·0]). Nationally, Qatar had the world’s highest age-specific prevalence of diabetes, at 76·1% (73·1–79·5) in individuals aged 75–79 years. Total diabetes prevalence—especially among older adults—primarily reflects type 2 diabetes, which in 2021 accounted for 96·0% (95·1–96·8) of diabetes cases and 95·4% (94·9–95·9) of diabetes DALYs worldwide. In 2021, 52·2% (25·5–71·8) of global type 2 diabetes DALYs were attributable to high BMI. The contribution of high BMI to type 2 diabetes DALYs rose by 24·3% (18·5–30·4) worldwide between 1990 and 2021. By 2050, more than 1·31 billion (1·22–1·39) people are projected to have diabetes, with expected age-standardised total diabetes prevalence rates greater than 10% in two super-regions: 16·8% (16·1–17·6) in north Africa and the Middle East and 11·3% (10·8–11·9) in Latin America and Caribbean. By 2050, 89 (43·6%) of 204 countries and territories will have an age-standardised rate greater than 10%.Peer ReviewedPostprint (published version

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Flocking behaviour of a resident population of the Great Indian Bustard Ardeotis nigriceps (Vigors)

During the non-breeding season, males of an area join and move, forage and roost together. Females also move in flocks or with their juveniles. Mixed flocks are rare and temporary. Female with a juvenile generally join a female flock but never a male flock. Mean flock size varies from season to season. The largest flocks are seen just before the breeding season and the smallest flocks during the breeding season. Number of pecks per five minutes were studied (1 271 observations). Although the bustards move in flocks, they do not help each other in locating food and perhaps also in locating danger, because there was no significant difference in the peck rates between a solitary and a non-solitary bird. There was some difference in the peck rate between the sexes. This could be because a hen, due to her smaller size, is vulnerable to more predators than the much larger male, so she has to look for danger more often, hence spends less time/5 minutes in foraging. Secondly, as the male is nearly twice the weight of a female, it needs more food, so more pecks/5 minutes. There was significant difference in the peck rate between a breeding hen and a non-breeding hen. This could be mainly because a hen with an egg or a small chick has to constantly look f or danger, thus she has less time for foraging.En dehors de la saison de reproduction, les mâles de la Grande Outarde Indienne Ardeotis nigriceps(Vigors) se regroupent, se déplacent, et se nourrissent ensemble. Les femelles forment également des groupes, seules ou avec leurs jeunes. Les groupes mixtes sont rares et temporaires. Une femelle accompagnée de son jeune rejoint toujours un groupe de femelles, et jamais un groupe de mâles. La taille moyenne de ces groupes sociaux varie d’une saison à l’autre. Les plus nombreux s’observent juste avant la période de reproduction, et les plus petits pendant cette dernière. Pour quantifier l’intensité de la recherche de nourriture chez les outardes, on a évalué le «taux de picorage » des oiseaux (nombre de coups de bec par 5 minutes ; 1 271 observations). On peut ainsi montrer que la vie en groupe ne facilite nullement la localisation de la nourriture chez les outardes, ni peut-être même la détection des sources de danger. On ne constate en effet aucune différence significative entre le nombre de coups de bec donnés par les oiseaux solitaires et ceux en groupe. Il existe, par contre, une certaine différence entre les deux sexes. La cause en est à rechercher peut-être dans la moindre taille de la femelle, plus vulnérable vis-à-vis des prédateurs que le mâle qui est beaucoup plus gros. La femelle doit donc être en alerte plus souvent, et passe ainsi moins de temps à rechercher sa nourriture. Par ailleurs, le fait d’être deux fois plus lourd que sa femelle force le mâle à manger plus, d’où le plus grand nombre de coups de bec donnés par 5 minutes. Il y a aussi une différence significative entre le «taux de picorage » d’une femelle couveuse et celui d’une non-couveuse. Cela pourrait être dû au besoin de la première d’être constamment attentive pour détecter un danger potentiel, ce qui réduit d’autant le temps disponible pour la recherche de la nourriture.Rahmani Asad rafi.
