Background: Functional training, also known as CrossFit, is a unique sport that combines weightlifting, gymnastics, and metabolic conditioning into a single program. There are an estimated 50 functional training centers in Malaysia. Purpose: To analyze the injury rates, patterns, and risk factors of functional training/CrossFit. Study Design: Descriptive epidemiology study. Methods: Electronic questionnaires were distributed to 244 participants from 15 centers in the country. Descriptive data regarding the athletes, injury occurrence within the past 6 months, injury details, and risk factors were collected. Results: Of the 244 athletes, 112 (46%) developed at least 1 new injury over the previous 6 months. Injury rates were significantly higher in athletes from nonaffiliate training gyms compared with CrossFit-affiliated gyms, in athletes with previous injuries, and in those who perceived themselves as having more than average fitness. Conclusion: Coaches and athletes need to be more aware of risk factors for injury to enable safer and better training strategies.
Background: Liver is an essential metabolic organ. It can be damaged due to prolonged use and higher doses of drugs, exposure to some chemicals, toxins, or infectious agents. Herbal plants as ashwagandha (Withania somnifera) may have free radical scavenging activity thereby can be used for the prevention and treatment of liver damage. Objective: To observe the effect of ashwagandha (Withania somnifera) root extract on gentamicin induced changes of some liver marker enzymes e,g serum aspartate amino transferase (AST ) and alanine amino transferase (ALT) in Wistar albino rats. Methods: This experimental study was carried out in the Department of Physiology, Sir Salimullah Medical College (SSMC), Dhaka from 1 st July 2010 to 30 th June 2011. A total number of 35 Wistar albino rats, aged 90 to 120 days, weighing between 150 to 200 grams were selected for the study. After acclimatization for 14 days, they were divided into control group (Group A) and experimental group (Group B). Control group was again subdivided into group A 1 (baseline control, consisted of 10 rats) and group A 2 (gentamicin treated control group, consisted of 10 rats). Again, experimental group (Group B-ashwagandha pretreated and gentamicin treated group) consisted of 15 rats. All groups of animals received basal diet for 22 consecutive days. In addition to this, group A 2 also received gentamicin subcutaneously (100mg /kg body weight/day) for the last eight (15 th to 22 nd day) consecutive days. Again, group B received ashwagandha root extract (500mg/kg body weight/day, orally) for 22 consecutive days and gentamicin subcutaneously (100mg/kg body weight /day) for last eight (15 th to 22 nd day) days. All the animals were sacrificed on 23 rd day. Then blood and liver samples were collected. For assessment of liver function, serum AST, ALT and bilirubin levels were estimated. All these tests were done by standard Laboratory technique. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Results: The mean serum levels of AST and ALT were significantly (p<0.001) higher in gentamicin treated control group and in ashwagandha pretreated and gentamicin treated group in comparison to those of baseline control group. . Again, these levels were significantly (p<0.001) lower in ashwagandha pretreated and gentamicin treated group than those of gentamicin treated control group. Conclusion: Ashwagandha (Withania somnifera) root extract restored serum AST, ALT towards normal levels in gentamicin intoxicated rats which may be due to its free radical scavenging activity. Therefore it may have hepatoprotective effect.
The incidence of pulmonary tuberculosis (PTB) can be reduced by preventing transmission with rapid and precise case detection and early treatment. The Gene-Xpert MTB/RIF assay is a useful tool for detecting Mycobacterium tuberculosis (MTB) with rifampicin resistance within approximately two hours by using a nucleic acid amplification technique. This study was designed to reduce the underdiagnosis of smear-negative pulmonary TB and to assess the clinical and radiological characteristics of PTB patients. This cross-sectional study included 235 participants who went to the Luyang primary health care clinic from September 2016 to June 2017. The demographic data were analyzed to investigate the association of patient gender, age group, and ethnicity by chi-square test. To assess the efficacy of the diagnostic test, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated. The area under the curve for sputum for both AFB and gene-Xpert was analyzed to compare their accuracy in diagnosing TB. In this study, TB was more common in males than in females. The majority (50.71%) of the cases belonged to the 25–44-year-old age group and the Bajau ethnicity (57.74%). Out of 50 pulmonary TB cases (smear-positive with AFB staining), 49 samples were positive according to the Gene-Xpert MTB/RIF assay and was confirmed by MTB culture. However, out of 185 smear-negative presumptive cases, 21 cases were positive by Gene-Xpert MTB/RIF assay in that a sample showed drug resistance, and these results were confirmed by MTB culture, showing resistance to isoniazid. In comparison to sputum for AFB, Gene-Xpert showed more sensitivity and specificity with almost complete accuracy. The additional 21 PTB cases detection from the presumptive cases by GeneXpert had significant impact compared to initial observation by the routine tests which overcame the diagnostic challenges and ambiguities.
Several anatomical variations concerning the median nerve have surfaced in the medical literature. Among them, bifid median nerve or median nerve bifurcation with or without persistent median artery has been widely reported. Sporadic case reports describe median nerve trifurcation (trifid median nerve) as well. In the present report, we describe carpal tunnel syndrome manifestations in association with trifid median nerve unveiled incidentally under high-frequency musculoskeletal ultrasonogram in a lactating mother-a first in the medical literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
