Conjugate Gradient (CG) methods are widely used for solving large-scale nonlinear systems of equations arising in various real-life applications due to their efficiency in employing vector operations. However, the global convergence analysis of CG methods remains a significant challenge. In response, this study proposes scaled versions of CG parameters based on the renowned Barzilai-Borwein approach for solving convex-constrained monotone nonlinear equations.

Article Synopsis
  • Secondary peritonitis is a significant cause of sepsis globally, particularly in resource-limited areas like Uganda, prompting a study to assess bacterial infections and susceptibility among surgical patients.
  • Conducted at Hoima Regional Referral Hospital, the study involved 126 patients, identifying that 45.2% had secondary peritonitis, with Escherichia coli and Klebsiella spp being the most common bacteria isolated.
  • Results indicated that certain antibiotics, like Imipenem and Amikacin, were effective against these infections, and males or those presenting late after symptom onset were more likely to have secondary peritonitis, emphasizing the need for early medical attention.

Article Synopsis
  • A study was conducted in Uganda comparing the costs and efficiency of open hemorrhoidectomy (OH) procedures using local anesthesia (LA) versus saddle block (SB) for patients with severe hemorrhoids (3rd or 4th degree).
  • The trial involved 58 patients and found that surgery using LA resulted in a significantly shorter operating time (15.5 minutes) and was less expensive ($57.42) compared to SB (33.7 minutes and $63.38).
  • The researchers concluded that using LA is more cost-effective and can help increase patient turnover in low-income countries, suggesting that policymakers should prioritize this method to meet global surgery goals by 2030.

Background: Prolonged post-operative ileus is associated with increased risk of other complications, length of hospital stays and health care related costs. Chewing gum has been shown to reduce duration of ileus in many elective surgeries, but there is a paucity of randomised controlled trials (RCTs) on its effect on duration of ileus among patients undergoing emergency surgery, specifically patients with peritonitis. The aim of this study is to determine the effect of chewing gum on duration of postoperative ileus following laparotomy for gastroduodenal perforations.

Populations of many galliform species have declined mainly due to habitat loss and over-hunting, notably the Congo peacock, which has been classified as a vulnerable species by the International Union for Conservation of Nature (IUCN). The domestic turkey, being a species of least concern, which has been reported to be closely related to peacocks, could serve as a model for the optimization of assisted reproductive technologies for the Congo peacock. This study was aimed at developing a suitable turkey semen extender for artificial insemination in field conditions.
