Background: Using antibiotics without a prescription is potentially unsafe and may increase the risk of antimicrobial resistance. We evaluated the effect of patient, health system, and clinical encounter factors on intention to use antibiotics without a prescription that were (1) purchased in the United States, (2) obtained from friends or relatives, (3) purchased abroad, or (4) from any of these sources.

Methods: The survey was performed January 2020-June 2021 in 6 publicly funded primary care clinics and 2 private emergency departments in Texas, United States.

Hyperglycemia induced reactive oxygen species oxidize macromolecules including cellular proteins leading to their accumulation in Endoplasmic Reticulum (ER) lumen which in turn activates unfolded protein response (UPR) sensors including, PERK (Protein Kinase RNA-Like ER Kinase). Activated PERK induces ER associated degradation of misfolded proteins to lower the ER stress. In the present study, we hypothesized that ER stress leads to the degradation of glucose transporter proteins resulting in complex glucose metabolism.

Background: Acute type A aortic dissection (ATAAD) is life-threatening and requires immediate surgery. Sudden chest pain may lead to a risk of misdiagnosis as an acute coronary syndrome and may lead to subsequent antiplatelet therapy (APT). We used the Chinese Acute Aortic Syndrome (AAS) Collaboration Database to study the effects of APT on clinical outcomes.

Objectives: The objective of our study was to evaluate the impact of a multifaceted stewardship intervention on adherence to the evidence-based practice guidelines on treatment of uncomplicated cystitis in primary care. We hypothesised that our intervention would increase guideline adherence in terms of antibiotic choice and duration of treatment.

Design: A preintervention and postintervention comparison with a contemporaneous control group was performed.

Cadmium is a highly mobile toxic heavy metal and a serious hazard to the biosphere. We studied uptake, accumulation and elimination of cadmium in a soil - faba bean - aphid - ladybird food chain. The soil in the study was amended with Cd at concentrations 0, 5, 10, 20 and, 30 mg kg (w/w).

The study aims at investigating the efficacy of individual as well as combined application of AM fungi (Glomus macrocarpum) and ZnO nanoparticles on the uptake of lead and its toxicity in wheat (Triticum aestivum L.). The plants were grown in pots with different treatments of AM Fungi, ZnO NP, and Pb.

Objective: To validate the use of electronic algorithms based on International Classification of Diseases (ICD)-10 codes to identify outpatient visits for urinary tract infections (UTI), one of the most common reasons for antibiotic prescriptions.

Methods: ICD-10 symptom codes (e.g.

Background: Reconstruction of the aorto-mitral curtain (AMC) for invasive double-valve infective endocarditis (IE) is a rare and challenging procedure. This study presents the short- and mid-term results of reconstruction of AMC in a single center.

Methods: From 2016 to 2019, 14 patients with invasive double-valve underwent surgical reconstruction of the AMC, along with either double valve replacement or aortic valve replacement with mitral valve repair.

Inappropriate choices and durations of therapy for urinary tract infections (UTI) are a common and widespread problem. In this qualitative study, we sought to understand why primary care providers (PCPs) choose certain antibiotics or durations of treatment and the sources of information they rely upon to guide antibiotic-prescribing decisions. We conducted semi-structured interviews with 18 PCPs in two family medicine clinics focused on antibiotic-prescribing decisions for UTIs.

Article Synopsis
  • Lead (Pb) contamination is a persistent problem in agroecosystems, accumulating in soil and causing harm to organisms, prompting this study to investigate Pb transfer through the broad bean-aphid-ladybird food chain.
  • The research found that Pb levels increased in plants, aphids, and ladybirds in direct relation to Pb concentrations in the soil, indicating biomagnification from soil to plants but a decrease in transfer efficiency at higher trophic levels, suggesting possible detoxification processes among the aphids and ladybirds.
  • Additionally, high Pb levels adversely impacted ladybird biomass and predation rates, revealing potential sub-lethal effects, necessitating more detailed studies to understand how ladybirds can manage Pb stress at cellular levels.

The present study investigates the extent of biotransfer and bioaccumulation of cadmium (Cd), lead (Pb) and zinc (Zn) from fly ash amended soil in mustard (Brassica juncea)-aphid (Lipaphis erysimi)-beetle (Coccinella septempunctata) food chain and its subsequent implications for the beetle. The soil was amended with fly ash at the rates of 0, 5, 10, 20 and 40% (w/w). Our results showed that the uptake of Cd, Pb and Zn from soil to mustard root increased with the increase in fly ash application rates, but their root to shoot translocation was relatively restricted.

Article Synopsis
  • Foot ulcers are a common and serious complication of diabetes that don't respond well to standard treatments.
  • A study involving 30 type 2 diabetes patients evaluated the effectiveness of low-level laser therapy (LLLT) compared to conventional treatment alone for treating foot ulcers.
  • Results showed that patients receiving LLLT experienced a significantly greater reduction in ulcer size after two weeks (37% reduction vs. 15% in the control group), indicating that LLLT is helpful alongside standard therapy.

The contamination of agroecosystems due to the presence of trace elements in commonly used agricultural materials is a serious issue. The most contaminated material is usually sewage sludge, and the sustainable use of this material within agriculture is a major concern. This study addresses a key issue in this respect, the fate of trace metals applied to soil in food chains.

Objective: To determine the overall efficacy and predictors of success of the penile preputial flap in the management of complex urethral strictures >2.5 cm in length.

Patients And Methods: We performed a retrospective and prospective study of 58 patients undergoing single-stage penile preputial flap urethroplasty for complex long-segment urethral strictures, without lichen sclerosus, repaired between May 2005 and April 2012 at our institution.

Introduction: Urethral strictures remain a reconstructive dilemma, due to high incidence of recurrence and less than satisfactory outcomes. Even experienced surgeons following strict surgical principles have not achieved optimal results, leading us to think whether the etiology of strictures dictate the outcome . We evaluated this "cause-effect" relationship highlighting the significance of the etiology on the overall prognosis of urethral strictures.

Introduction: Urethral strictures remain a reconstructive dilemma due to high incidence of recurrence and unsatisfactory outcomes. Pelvic trauma remains the foremost etiology leading to morbidity. We evaluated this "cause-effect" relationship of pelvic trauma to stricture outcome, to replenish our understanding of contemporary urethral strictures and highlight significance of type, degree and influence of primary management of pelvic trauma on the overall prognosis of urethral strictures.
