Background: Surgical and conservative methods have been reported by various studies for high rates of fracture union and subsequent regain of function among patients with undisplaced or minimally-displaced scaphoid fractures. Hence, this study aims to analyze the best available evidence to comprehend the relative benefits and risks of these therapeutic options. Methods: A systematic search of the literature from different databases and search engines was performed with strict eligibility criteria to obtain the highest quality of evidence. All randomized controlled trials delineating the outcomes of surgical versus conservative treatments for acute undisplaced or minimally-displaced scaphoid fractures were included and then evaluated using scoring tools: Cochrane risk of bias tool and PEDro scale. Data were pooled using random-effects models with standard mean differences for continuous outcomes and risk ratios for dichotomous variables. Results: The search yielded 339 potentially related articles, further trimmed down to eight studies based on the eligibility criteria. The meta-analysis revealed that surgical treatment resulted in significantly better functional outcomes than conservative treatment. Furthermore, surgery resulted in the prevention of delayed union of fractures and reduction of time needed to return to work. Conclusions: While four studies reported advantages of surgical treatment, evidence was insufficient to provide a definitive conclusion that surgery is a better option. Due to the significant limitations with respect to certain variables, the superiority of one method to the other could not be established.

The anti-apoptotic effect of (-)-epigallocatechin-3-gallate (EGCG) during unilateral testicular torsion and detorsion (TT/D) was established in our previous study. In mice, the smallest inhibitor of apoptosis, survivin, is alternatively spliced into three variants, each suggested to have a unique function. Here, we assessed how EGCG exerts its protective effect through the expression of the different survivin splice variants and determined its effect on the morphology of the seminiferous tubules during TT/D. Three mouse groups were used: sham, TT/D+vehicle and TT/D treated with EGCG. The expression of the survivin variants (140 and 40) and other apoptosis genes (p53, Bax and Bcl-2) was measured with semi-quantitative RT-PCR. Histological analysis was performed to assess DNA fragmentation, damage to spermatogenesis and morphometric changes in the seminiferous tubules. In the TT/D+vehicle group, survivin 140 expression was markedly decreased, whereas survivin 40 expression was not significantly different. In parallel, there was an increase in the mRNA level of p53 and the Bax to Bcl-2 ratio in support of apoptosis induction. Histological analyses revealed increased DNA fragmentation and increased damage to spermatogenesis associated with decreased seminiferous tubular diameter and decreased germinal epithelial cell thickness in the TT/D+vehicle group. These changes were reversed to almost sham levels upon EGCG treatment. Our data indicate that EGCG protects the testis from TT/D-induced damage by protecting the morphology of the seminiferous tubules and modulating survivin 140 expression.

The outbreak of a recent strain of Coronavirus, known as 'COVID-19', has spread sharply from China across the globe, resulting in a dramatic recession in the global economy. This uncertainty has therefore negatively influenced the business perspective and the various formulated strategies that may not considered such [extreme] circumstances. Using baseline analysis and archival data, this paper reports some of the major implications of COVID-19 on global business and strategy and puts forward suggested research agenda as potential future directions for organizations. In order to survive and remain sustainable, this paper argues that businesses need to revisit their strategies during current COVID-19 crises from three perspectives, including supporting human resources financial commitment, forming cross-functional teams and connecting with their supply chains, as well as investing in corporate social responsibility and doubling down efforts with regard to partnerships. The study also represents a preliminary analysis to the implications of COVID-19 on the business and strategies across the globe and is considered the first such in the field of business, as to date all research papers on COVID-19 have been published in medical-related journals. Directions for future research are also proposed at the end of this study.

This study has been conducted with the aim of detecting possible links between the structural features of English-Arabic dictionaries and errors made by 46 English majors at Kuwait University when translating individual items they encountered in current English texts. Specially designed look-up records were used by the subjects for each problematic word. It was found that success rates decrease when long entries of polysemous words are consulted and that the average location of needed senses is some distance away from the average location of senses that these users actually extracted from their bilingual dictionary. Some of the students' erroneous translations were attributed to the problematic macro- and microstructural design features of the English-Arabic dictionary: method of sense ordering, untranslated derivatives, spacing between monosemous entries, typeface size, etc. The study also detected a role of structural effects of the translated text e.g. word division at line endings. The users were also responsible for some of these errors, e.g. by misreading the item in the text especially in cases of English confusables.
