Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Peritoneal seeding of embolic beads after uterine artery embolization.

Background: Incidental identification of peritoneal nodules during laparoscopy may present a diagnostic dilemma. The differential diagnosis includes a variety of benign and malignant entities such as peritoneal carcinomatosis.

Case: A 44-year-old G2P2 woman presented with recurrent menorrhagia and pelvic pain was found to have large uterine fibroids on imaging studies.

Steroid hormone synthesis by the ovarian stroma surrounding epithelial ovarian tumors: a potential mechanism in ovarian tumorigenesis.

Epithelial ovarian tumors are responsive to steroid hormone stimulation and the ovarian stroma may have a direct role in this process. We evaluated immunohistochemical markers of sex-steroid differentiation and steroidogenesis (calretinin, inhibin, steroidogenic factor 1), steroid enzymes involved in hormone biosynthesis (CYP17, CYP19, HSD17β1, AKR1C3), and hormone receptors (estrogen receptor, progesterone receptor, and androgen receptor) in 101 epithelial ovarian tumors and in normal structures implicated in ovarian carcinogenesis (ovarian surface epithelium and cortical inclusion cysts) in an attempt to elucidate this process. We hypothesized that ovarian stroma immediately adjacent to tumors express markers of sex-steroid differentiation and steroidogenesis and steroid enzymes whereas the epithelium contains corresponding hormone receptors.

Perceptions of ad hoc supervision encounters in general practice training: A qualitative interview-based study.

Background: Ad hoc supervision encounters occur between general practitioner (GP) supervisors and general practice registrars outside scheduled teaching sessions. Anecdotally reported as important learning opportunities, these encounters are rarely explored in the literature.

Objective: This study examined supervisors', registrars' and practice managers' perceptions of ad hoc supervisory encounters.

Incidental serous tubal intraepithelial carcinoma and early invasive serous carcinoma in the nonprophylactic setting: analysis of a case series.

A precursor for invasive ovarian/pelvic high-grade serous carcinoma, termed serous tubal intraepithelial carcinoma (STIC), has been identified and characterized through careful analysis of the fallopian tubes in both prophylactic salpingo-oophorectomy specimens obtained from women with either a family history of breast and/or ovarian cancer or germline mutations of BRCA1 and BRCA2 and in cases of pelvic high-grade serous carcinoma. Data on incidental STICs and clinically occult microscopic invasive high-grade serous carcinomas are limited. We analyzed the clinicopathologic features of 22 cases, including 15 pure STICs and 7 STICs associated with microscopic invasive high-grade serous carcinomas, identified incidentally in fallopian tubes removed for nonprophylactic indications.

Lynch syndrome screening in newly diagnosed colorectal cancer in general pathology practice: from the revised Bethesda guidelines to a universal approach.

Objective: Lynch syndrome (LS) is the most common hereditary form of colorectal cancer (CRC). The revised 2004 Bethesda guidelines were developed to identify potential LS patients. This study aimed to retrospectively evaluate utilization and adequacy of the guidelines in general pathology practice and to determine if a universal LS screening approach increased the potential LS detection rate in newly diagnosed CRCs.

Trends and challenges in the management of tracheostomy in older people: the need for a multidisciplinary team approach.

The trend towards increasing representation of older people as recipients of health care in acute care settings is matched with a corresponding increase in the numbers of older people undergoing tracheostomy.The reasons for tracheostomy in this age group are varied, including respiratory failure, neurological injury/event and carcinomas. Further, current research supports early tracheostomy for patients requiring medium to long-term ventilation and unconscious patients at risk of airway obstruction.
