Labor clauses in trade agreements: Hidden protectionism?

Rev Int Organ 2022 29;17(3):453-483. Epub 2021 May 29.

World Trade Institute, University of Bern, Bern, Switzerland.

We explore the impact of the introduction and design of labor clauses (LCs) in preferential trade agreements (PTAs) on bilateral trade flows over the period 1990-2014. While it is not a priori clear if the inclusion of LCs in PTAs will decrease or increase bilateral trade, we expect the direction of trade to matter, that is, we expect to observe the (negative or positive) impact of LCs in the South-North trade configuration. We also expect, in that configuration, stronger LCs to yield stronger (negative or positive) effects on bilateral trade flows. Read More

Acute appendicitis is one of the most common surgical emergencies encountered. Although studies have reported a rise in the number of cases over the past decade in Western countries, appendicitis is comparatively lower in Asian countries, mainly due to the prevailing dietary habits. Acute appendicitis can further complicate as either appendicular abscess or an appendicular lump or culminate into peritonitis following gangrene/rupture. Read More

Appendix and Ulcerative Colitis: a Key to Explaining the Pathogenesis and Directing Novel Therapies?

Inflamm Bowel Dis 2022 Jun 24. Epub 2022 Jun 24.

Centre of Excellence for Gastrointestinal Inflammation and Immunity Research, University of Alberta, Edmonton, AB, T6G 2X8, Canada.

The vermiform appendix is generally considered a redundant organ, but recent evidence suggests that the appendix could contribute to the pathogenesis of inflammatory bowel diseases, in particular ulcerative colitis (UC), and may even have a therapeutic role; however, mechanisms of the appendix involvement remain unclear. Here, we highlight current evidence on the link between the appendix and UC and consider plausible therapeutic implications. A literature search was conducted using PubMed and PubMed Central from inception to Nov 2021 using the terms "Appendix", "UC", "Appendix & UC," "Appendectomy", and "Peri-appendicular patch," including only articles published in English.

Department of Internal Medicine, Faculty of Medicine, Sohag University, Sohag 82725, Egypt.

In 1921; Masson and Maresch first coined the term "neurogenic appendicitis (NA)" to describe "neuroma-like" lesions in the appendix. To date, our knowledge about NA is limited; therefore, we conducted a comprehensive analysis of the literature (1921 to 2020) to examine the clinicopathological features of NA.

Vermiform Appendix and the Potential for Missed Pathologies.

Cureus 2022 May 16;14(5):e25055. Epub 2022 May 16.

Pathology, Jawaharlal Institute of Postgraduate Medical Education & Research, Puducherry, IND.

Introduction The appendix is considered an appendage of little value and is often treated disdainfully, be it as part of evolutionary process, on a grossing table, under a microscope or while archiving specimens and slides. It is only recently, with data indicating its importance in gut immunity and as the origin of pseudomyxoma, that its space in a human body appears vindicated. Aim Our aim was to screen the histopathologic spectrum of appendix lesions observed in our hospital for rare, incidental or clinico-radiologically uncertain lesions that would help emphasize a necessary seriousness in its sampling.

A Case of Internet Gaming Disorder: When #Play Apart Together Takes a Dark Turn.

J Community Hosp Intern Med Perspect 2022 31;12(1):32-35. Epub 2022 Jan 31.

Department of Medical Education, Rochester Regional Health, Rochester, NY, USA.

Background: The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) places internet Gaming disorder (IGD) in its research appendix as a potential new behavioral addiction diagnosis that requires further investigation. As part of the media campaign #HealthyAtHome, recommendation to relieve stress and anxiety during COVID-19, the World Health Organization (WHO) advocated for the playing of video games. The encouragement and expansion of playing video games may have led to the unintentional consequence of increasing the prevalence of IGD as IGD has been postulated to be a maladaptive response to stress.
