An Abattoir Based Study on Brucellosis, Bovine Tuberculosis and Paratuberculosis in Buffaloes and Cattle at Faisalabad, Pakistan

A study was carried out to investigate the prevalence of these diseases at Faisalabad abattoirs in buffaloes and cattle. For this purpose, 400 consecutive animals, including 200 buffaloes and 200 cattle were included in the study. Blood and diseased organ, tissue samples were collected for further processing. For a study on the prevalence of brucellosis, the serum samples were screened by RBPT (Rose Bengal Precipitation Test). The overall prevalence of brucellosis recorded was 10% and 11% in buffaloes and cattle, respectively. The prevalence of brucellosis did not vary between male and females, three age groups and three weight groups each in buffalo and cattle. However, the odds of contracting brucellosis were 3.8 vs 1 for cattle than buffalo at an age below 5 years. On the basis of specific gross and histopathological lesions in different organs/tissues, including lungs, liver, lymph nodes and intestine, the prevalence of bovine tuberculosis and paratuberculosis were assessed. The suspected prevalence of bovine tuberculosis was 1.5% and 1%, while it was 3.75% and 4.1 % in case of paratuberculosis in buffaloes and cattle, respectively. The cattle revealed significant (P = 0.05) difference between age groups on the basis of suspected lesions of tuberculosis in lungs with young cattle showing the lesions more than adult, but it was not so in buffaloes. The odds of contracting paratuberculosis in males were 3.74 vs 1 of buffalo than cattle. The other comparisons were not marked between age groups, sex and weight groups between buffaloes and cattle. The prevalence of these diseases is not unexpected in abattoir and is a threat not only for workers at the slaughterhouse, meat sellers (butchers) but also to the general public

Jeopardies of Aversive Leadership: A Conservation of Resources Theory Approach

The research on the dark side of leadership is still in its infancy. We have contributed to this line of research by proposing that work alienation acts as an underlying mechanism through which aversive leadership results in reduced job performance. We further propose that psychological capital (PsyCap) acts as an important personal resource that reduces the negative effects of aversive leadership in the form of work alienation. The proposed model gets its support from the conversation of resources theory given by Hobfoll (1989) which suggests that stressful situation like an aversive leadership results in the loss of employee resources as a result of that he/she indulges in work alienation and shows poor job performance to retain back the lost resources. People with better personal resources in the form of PsyCap are better able to cope-up with the aversive leader behavior and make them able to avoid work alienation. It is a time-lagged study. The data for the current study was collected from 321 employees working in the service sector organizations, particularly universities, banks and telecom organizations, through personally administered questionnaires. The results supported the mediation and moderation hypothesis. Limitations and future research along with theoretical and practical implications are given at the end

Prevalence of obesity in patients suffering from migraine

Background: Migraine is one of the most common primary headaches, accounting for significant morbidity in patients suffering from it. An association between obesity and migraine has been documented in the past, despite some studies pointing to the contrary. Author’s purpose is to calculate the prevalence of obesity in migraine patients in order to contribute to the existing concepts. A positive correlation could lead to the employment of weight loss interventions in the management of obese patients with migraine.Methods: In this cross-sectional study, 400 patients, recently diagnosed with migraine, attending the Neurology Outpatient Department at the Dr. Ruth KM Pfau Civil Hospital Karachi were enrolled after taking informed consent.  Migraine was diagnosed using International Classification of Headache Disorders III (ICHD III) criteria. Height (meters) and weight (kilograms) were measured and body mass index calculated. This data was kept confidential. The results were tabulated and analyzed using SPSS version 19.  Continuous quantitative data were analyzed using chi square test. A p Value of less than or equal to 0.05 was considered significant.Results: The mean age of enrolled participants was 30.69±6.96 years, 204(51%) were >30 years of age, 159(39.8%) were male and 241(60.3%) were female, mean height was 1.55±0.1 meters, mean weight was 56.26±12.98 kg, and mean duration of migraine was 5.04±2.02 weeks. The prevalence of obesity in patients with migraine was 108 (27%).Conclusions: It was concluded that the prevalence of obesity in patients with migraine was 27%

Advantages and Disadvantages of Using St. John\u27s Wort as a Treatment for Depression

BACKGROUND AND OBJECTIVES: St. John\u27s wort (SJW) extracts are currently being used to treat depression of various degrees of severity. While many studies have shown it to be superior to placebo, data regarding the effectiveness of using SJW as a stand-alone treatment compared with standard antidepressants has yet to be proven conclusively. This study aims to understand the advantages and disadvantages of SJW as a treatment modality for depression. METHODS: The authors searched PubMed, JAMA network, Springer Link, Elsevier, Google Scholar, and Scientific Progress databases, from 2011 through August 2021, using the following keywords: St John\u27s wort, Hypericum perforatum, depression, antidepressant, complementary alternative medicine, economic evaluation depression St. wort, St John\u27s wort and depression, antidepressant interactions. This yielded a total of 27 papers following a thorough removal of irrelevant content and dissemination in languages other than English. RESULTS: In patients with mild and moderate depression, SJW proved superior to placebo. Certain studies comparing the efficacy of SJW versus selective serotonin reuptake inhibitors (SSRIs), especially fluoxetine, reported SJW to be more efficacious, while the majority reported no significant difference. Tricyclic antidepressants were also found to have similar efficacy as SJW. Moreover, treatment with SJW was also found to reduce postmenopausal depression. Regarding the safety profile, although SJW is better tolerated with fewer adverse effects when compared to standardized antidepressants, its predisposition to causing fatal serotonin syndrome, when used in conjunction with other serotonergic agents and drug interactions noted with CYP 450 drugs, raises a question in the safety profile. CONCLUSION: It is essential to acknowledge that SJW has been used as a treatment measure in Germany. Despite being only listed as a dietary supplement by the FDA and not a drug, SJW has shown to be comparable, if not more efficacious, than most standard treatment options for depression. SJW does prove to be an exciting piece of pharmacotherapy in the realm of mental health and post-menopausal treatment. More prospective studies will help us better understand its efficacy in mild and moderate depression and its ability to serve as a long-term agent. Considering its mechanism of action, its role in relieving patients suffering from an anxiety disorder is also worth considering

A copper diimine‐based honeycomb‐like porous network as an efficient reduction catalyst

Nitrophenols are among the widely used industrial chemicals worldwide; however, their hazardous effects on environment are a major concern nowadays. Therefore, the conversion of environmentally detrimental p‐nitrophenol (PNP) to industrially valuable p‐aminophenol (PAP), a prototype reaction, is an important organic transformation reaction. However, the traditional conversion of PNP to PAP is an expensive and environmentally unfriendly process. Here, we report a honeycomb‐like porous network with zeolite‐like channels formed by the self‐organization of copper, 1,10‐phenanthroline, 4,4′‐bipyridine, and water. This porous network effectively catalyzed the transformation of hazardous PNP to pharmaceutically valued PAP. In the presence of complex, PNP to PAP conversion occurred in a few minutes, which is otherwise a very sluggish process. To assess the kinetics, the catalytic conversion of PNP to PAP was studied at five different temperatures. The linearity of lnCt/Co versus temperature plot indicated pseudo‐first‐order kinetics. The copper complex with zeolite like channels may find applications as a reduction catalyst both on laboratory and industrial scales and in green chemistry for the remediation of pollutants

Evidence that a very brief psychological intervention boosts weight loss in a weight loss program

Reducing morbidity and mortality associated with being overweight is a crucial public health goal. The aim of the present research was to test the efficacy of a very brief psychological intervention (a volitional help sheet) that could be used as an adjunct to standard weight loss programs to support increased weight loss in an overweight sample. Seventy-two overweight participants currently participating in a weight loss program were randomly allocated to either an intervention (volitional help sheet) condition or a control (distracter task) condition. The main outcome measure was weight at 1-month follow-up. Participants in both conditions lost significant amounts of weight, but those in the intervention condition lost significantly more than those in the control condition (d = 0.66). The findings support the efficacy of the volitional help sheet to promote additional weight loss in an overweight sample engaged in a weight loss program. The volitional help sheet therefore represents a very brief, low-cost intervention that could be used to supplement ongoing weight-loss programs

Fracture Risk in Men With Congestive Heart Failure Risk Reduction With Spironolactone

ObjectivesThe purpose of this study was to determine whether spironolactone use is associated with fractures in men with congestive heart failure (CHF).BackgroundIn rats with aldosteronism, spironolactone preserves skeletal strength. However, in humans, the relationship of spironolactone to fractures is not known.MethodsThe medical records of all male patients with CHF from 1999 to 2005 treated at the Veterans Affairs Medical Center, Memphis, Tennessee, were reviewed (n = 4,735). Odds ratios with 95% confidence intervals of having a fracture associated with spironolactone use were estimated using conditional logistic regression.ResultsWe identified 167 cases with a single-incident fracture and matched these by age and race to 668 control subjects without fractures. After adjustment for covariates, spironolactone use was inversely associated with total fracture (odds ratio: 0.575; 95% confidence interval: 0.346 to 0.955, p = 0.0324).ConclusionsThe use of spironolactone is inversely associated with fractures in men with CHF
