Servant leadership and citizenship behavior in the Pakistani tourism and hospitality industry: The role of harmonious environmental passion and a green work climate.

This research investigated the mechanisms and contextual factors influencing the relationship between servant leadership tailored to specific environments and environmental citizenship behavior, considering the Conservation of Resource Theory as a theoretical lens. Data collection was collected from 300 employees and their supervisors, including several organizations within the Pakistani Hospitality and Tourism sector, and the data underwent analysis using PLS-SEM. Empirical findings showed that the relationship between environmental-specific servant leadership and organizational environmental citizenship behavior is mediated by harmonious environmental passion. The green work climate positively moderates the indirect effects of harmonious environmental passion on organizational environmental citizenship behavior, suggesting that this effect is strengthened when employees have a higher green work climate than with a lower green work climate. Guidelines for future research are provided.

A Case of an IgG4-Related Disease Mimicking Malignancy and Resolving With Steroids.

A 77-year-old African American female was referred to oncology for evaluation of an adrenal fossa mass detected on computed tomography scan of the abdomen and pelvis (CT-scan A/P) that was ordered as a work-up for painless hematuria. Further evaluation by positron emission tomography (PET) scan showed hypermetabolic masses in the left suprarenal and right iliac region. The biopsy of the right iliac mass was consistent with IgG4-related disease (IgG4RD). It was supported by an elevated serum IgG4 level. She was treated with prednisone with a good response.

Primary isolated hepatosplenic sarcoidosis mimicking malignancy and causing symptomatic hypercalcaemia.

This is a case of a 67-year-old woman, known to have multiple medical problems, mainly papillary thyroid cancer status post-total thyroidectomy and cervical neck dissection in addition to radioactive iodine currently in remission for 1 year, who presented to the hospital with severe weakness and fatigue. The initial workup showed significant hypercalcaemia and suppressed Parathyroid hormone (PTH). The patient was treated with hydration and pamidronate and her hypercalcaemia and symptoms improved. The differential was wide, however, a CT scan of the chest, abdomen and pelvis did show multiple liver and splenic nodular lesions; therefore, malignancy was the highest possible diagnosis. Biopsy of the splenic lesion confirmed the diagnosis of sarcoidosis. Therefore, the patient was diagnosed with primary isolated nodular hepatosplenic sarcoidosis mimicking malignancy and causing significant symptomatic hypercalcaemia.

The role of vitamin D supplementation for primary prevention of cancer: meta-analysis of randomized controlled trials.

Background: In the USA cancer is the second leading cause of mortality, as such, primary prevention of cancer is a major public health concern. Vitamin D supplementation has been studied as a primary prevention method for multiple diseases including cardiovascular disease, osteoporosis, diabetes mellitus and cancer. The role of Vitamin D as primary prevention of cancer is still controversial. With fast emergence of large randomized controlled trials (RCTs) in that regards, we aimed to evaluate the efficacy of Vitamin D supplementation as primary prophylaxis for cancer. Methods: A comprehensive electronic database search was conducted for all RCTs where comparison of Vitamin D supplementation versus placebo for the prevention of any type of disease with at least 3 years of Vitamin D supplementation was used and where cancer incidence or mortality was reported. The primary outcome was cancer-related mortality and cancer incidence. We calculated risk ratios (RRs) and 95% confidence intervals (CIs) using a random-effects model at the longest follow-up. Results: We included 10 RCTs with 79,055 total patients, mean age of 68.07 years, a female percentage of 78.02% and a minimum follow-up of 4 years and more. Vitamin D was associated with significant reduction of cancer-related mortality compared with placebo (RR 0.87; 95% CI: 0.79-0.96; P = 0.05: I2 = 0%). Compared with placebo, Vitamin D was not associated with significant reduction of cancer incidence (RR: 0.96; 95% CI: 0.86-1.07; P = 0.46; I2 = 31%). Conclusion: With inclusion of studies, which did not primarily examine vitamin D for the purpose of preventing cancer or reducing cancer mortality our meta-analysis highlights that the use of vitamin D supplementation for primary prevention of cancer is encouraged as it does possibly decrease cancer-related mortality once cancer is diagnosed; however, it has no role or effect on cancer incidence.

Stage 1 small cell cancer of the vagina.

This is the case of a 56-year-old white woman with a medical history significant for chronic obstructive pulmonary disease, migraine, hypertension, tobacco abuse and hypercholesterolaemia. Her surgical history is significant for total hysterectomy and bilateral salpingo-oophorectomy for diffuse endometriosis. The patient presented with a vaginal lesion. The biopsy was positive for primary vaginal small cell carcinoma and human papilloma virus (HPV). Initial staging positron emission tomography (PET) scan confirmed stage 1 disease. The patient was started on chemotherapy with cisplatin and etoposide for four cycles, followed by concurrent chemotherapy with cisplatin/taxol and radiation therapy.
