FRACTURES OF THE PROXIMAL HUMERUS: MANAGEMENT AND EVALUATION (GENERAL OVERVIEW)

Abstract:

Fractures of the proximal humerus are a common phenomenon, while low-energy injuries occur in the elderly, and less frequent fractures with higher energy affect young people. The decision to perform surgical or nonsurgical treatment is determined by the functional goals and the degree of displacement of the proximal anatomical parts of the humerus. Surgical treatment is based on the ability to achieve and maintain the reduction, the vascularity of the articular segment, the quality of attachment of soft tissues and bone porosity. Despite numerous studies, the optimal treatment of significantly displaced fractures remains controversial. Keywords: fracture, humerus, fracture treatment.

Using Hyland’s (2000) model as a research tool and drawing on Hyland’s (2005a) model of metadiscourse, this article presents a pragmatic two-level rhetorical analysis of the constituent moves within research article abstracts. It specifically zeroes in on the identification and mapping of the most frequently used metadiscourse markers signifying these moves. The findings highlight that Libyan authors employ interactive markers more often than interactional ones. Both quantitative and qualitative analysis of metadiscourse indicate that transitions, endophoric markers, and frame markers emerge as the dominant interactive categories. In contrast, interactional metadiscourse is predominantly represented by attitude markers, hedges, and boosters. Based on the findings, Move 1 features the highest frequency of metadiscourse markers, followed by Move 2. Notably, transitions stand out as the most prevalent category across all moves. This study carries pedagogical implications for academic writing practices among Libyan academic writers and students alike. Moreover, it enhances the existing body of research on the genre of research articles.

Purpose

Since financial sector plays a critical economic role in Hong Kong, the current research aims to comprehensively analyze the association between financial development and economic growth in the country to draw correct conclusions about the impact that financial sector's development has on the growth of the economy. This requires both using of more comprehensive data that includes all or nearly all elements of the country's financial sector and utilizing advanced econometrics techniques to provide more reliable evidence based on the findings. In the study, both issues have been addressed more academically to aid the relevant authorities better.

Design/methodology/approach

This study empirically examines the financial development-economic growth nexus in Hong Kong employing data covering 1980–2019. The quantile-on-quantile (QQ) approach of Sim and Zhou (2015) is utilized to investigate certain subtle aspects of the association linking financial development and economic growth. In addition, the authors benefit from applying the nonlinear Granger causality test of Diks and Panchenko (2006) to assess the variables' nexus in a nonlinear manner.

Findings

In contrast to the evidence of a unidirectional linkage documented in many related studies, the empirical findings suggest that a bi-directional relationship exists between financial development and economic growth for Hong Kong. This is a helpful input for the relevant policymakers and implies that they can set appropriate policies and regulations to balance financial development and economic growth in this country.

Clostridioides difficile (C. difficile) is the most common pathogen causing antibiotic-associated intestinal diseases in humans and some animal species, but it can also be present in various environments outside hospitals. Thus, the objective of this study was to investigate the presence and the characteristics of toxin-encoding genes and antimicrobial resistance of C. difficile isolates from different environmental sources. C. difficile was found in 32 out of 81 samples (39.50%) after selective enrichment of spore-forming bacteria and in 45 samples (55.56%) using a TaqMan-based qPCR assay. A total of 169 C. difficile isolates were recovered from those 32 C. difficile-positive environmental samples. The majority of environmental C. difficile isolates were toxigenic, with many (88.75%) positive for tcdA and tcdB. Seventy-four isolates (43.78%) were positive for binary toxins, cdtA and cdtB, and 19 isolates were non-toxigenic. All the environmental C. difficile isolates were susceptible to vancomycin and metronidazole, and most isolates were resistant to ciprofloxacin (66.86%) and clindamycin (46.15%), followed by moxifloxacin (13.02%) and tetracycline (4.73%). Seventy-five isolates (44.38%) showed resistance to at least two of the tested antimicrobials. C. difficile strains are commonly present in various environmental sources contaminated by feces and could be a potential source of community-associated C. difficile infections.

Oil spills are an unavoidable risk during exploration, production, and transportation. In the event of an accident, the environmental impact is often severe and may even harm the local environment for decades. Therefore, there is a need to find a method and device that minimizes damage to the environment. Oil spill cleanup and remedy are still a challenge and raise global concern because of the many environmental complications associated with it. This chapter reviews existing methods and devices for oil spill cleanup, particularly the wetting phenomenon for oil absorption and membrane filtration methods for oil spill cleanup, and focuses on the properties of nanofiber materials and their use for manufacturing oil absorbents and cross-flow filtration membranes. In particular, this chapter discusses the performance, effectiveness, and applications of nanofibrous materials fabricated by the solution and hot melt …
