Sonografski prikaz dimenzija bubrega u bolesnika s esencijalnom hipertenzijom u sveučilišnoj bolnici Abubakar Tafawa Balewa u gradu Bauchi u Nigeriji

Introduction: Hypertension is one of the commonest non-communicable diseases worldwide; it is the second most common cause of end-stage renal disease. Objective: To evaluate the renal dimensions and volume of essential hypertension patients in Abubakar Tafawa Balewa University Teaching Hospital, Bauchi and to compare the dimensions with that of apparently healthy volunteers. Materials and Methods: A total of two hundred and eleven individuals (comprising 121 females and 90 males) with essential hypertension attending an outpatient clinic in Abubakar Tafawa Balewa University Teaching Hospital Bauchi, and an equal number of healthy volunteers (comprising of 172 females and 49 males) were studied as controls. Both the healthy volunteers and the Hypertensive patients’ renal length, renal width, antero-posterior diameter, and parenchymal thickness were assessed. Statistical Package for Social Sciences (SPSS version 20.0) was used for data analysis. Results: Study show the mean renal length for hypertensive patients to be 9.1 ± 0.79 cm and 9.1 ± 0.73 cm, the mean renal width of 3.5 ± 0.48 cm and 3.8 ± 0.68 cm, and mean renal volume of 87.22 ± 19.58 cm3 and 95.08 ± 22.93 cm3 for the right and left kidneys respectively. Results equally show statistically significant difference in anteroposterior diameter (p<0.05), parenchymal thickness (p<0.05) and renal volume (p<0.05) between the hypertensive group and the volunteer group for both right and left kidneys. Conclusion: This study has established baseline renal dimensions for hypertensive in our population (Bauchi Metropolis). The hypertensive subjects showed a decrease in renal anteroposterior diameter, parenchymal thickness and volume compared to control group.Uvod: Hipertenzija je jedna od najčešćih nezaraznih bolesti u svijetu; drugi je najčešći uzrok završnog stadija bubrežne bolesti. Cilj: Procijeniti dimenzije bubrega i bubrežni volumen kod hipertenzivnih bolesnika u Sveučilišnoj bolnici Abubakar Tafawa Balewa u gradu Bauchi i usporediti ih s dimenzijama kod naizgled zdravih ispitanika koji su se dobrovoljno javili za sudjelovanje u istraživanju. Materijali i metode: Uzorak se sastojao od dvjesto jedanaest ispitanika (121 žena i 90 muškaraca) koji boluju od esencijalne hipertenzije i na ambulantnom su liječenju u Sveučilišnoj bolnici Abubakar Tafawa Balewa u gradu Bauchi i jednakog broja zdravih ispitanika (172 žene i 49 muškaraca), koji su bili kontrolna skupina. Proučavana je duljina i širina bubrega, anteroposteriorni promjer i debljina parenhima kod ispitanika s hipertenzijom i kod zdravih ispitanika. Za analizu podataka primijenjen je statistički paket za društvene znanosti (SPSS verzija 20.0). Rezultati: Studija pokazuje da je prosječna dužina bubrega kod hipertenzivnih bolesnika 9,1 ± 0,79 cm i 9,1 ± 0,73 cm, prosječna bubrežna širina 3,5 ± 0,48 cm i 3,8 ± 0,68 cm, a prosječni bubrežni volumen 87,22 ± 19,58 cm3 i 95,08 ± 22,93 cm3 za desni i lijevi bubreg pojedinačno. Rezultati također pokazuju statistički značajnu razliku u anteroposteriornom promjeru (p < 0,05), debljini parenhima (p < 0,05) i bubrežnom volumenu (p < 0,05) između hipertenzivne skupine i kontrolne skupine za desni i lijevi bubreg. Zaključak: Ovom su studijom utvrđene osnovne bubrežne dimenzije kod hipertenzivnih bolesnika u populaciji grada Bauchi, glavnog grada Savezne države Bauchi u Nigeriji. Kod ispitanika koji boluju od hipertenzije ustanovljeno je smanjenje anteroposteriornog promjera bubrega, debljine parenhima i bubrežnog volumena u usporedbi s kontrolnom skupinom

A História da Alimentação: balizas historiográficas

Os M. pretenderam traçar um quadro da História da Alimentação, não como um novo ramo epistemológico da disciplina, mas como um campo em desenvolvimento de práticas e atividades especializadas, incluindo pesquisa, formação, publicações, associações, encontros acadêmicos, etc. Um breve relato das condições em que tal campo se assentou faz-se preceder de um panorama dos estudos de alimentação e temas correia tos, em geral, segundo cinco abardagens Ia biológica, a econômica, a social, a cultural e a filosófica!, assim como da identificação das contribuições mais relevantes da Antropologia, Arqueologia, Sociologia e Geografia. A fim de comentar a multiforme e volumosa bibliografia histórica, foi ela organizada segundo critérios morfológicos. A seguir, alguns tópicos importantes mereceram tratamento à parte: a fome, o alimento e o domínio religioso, as descobertas européias e a difusão mundial de alimentos, gosto e gastronomia. O artigo se encerra com um rápido balanço crítico da historiografia brasileira sobre o tema

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Current management strategies and therapeutic targets in chronic constipation

Constipated patients who are refractory to simple lifestyle interventions will usually resort to laxatives, whether prescribed or over the counter. Clinical trial evidence is scarce for older medications such as laxatives, especially with a condition as chronic and subjective as constipation. Newer polyethylene glycol-based laxatives have been investigated under rigorous clinical trial settings, but comparisons between different laxatives are not available. Newer prokinetic agents, targeting peristalsis, intestinal secretion and the colonic flora, have been developed for laxative refractory constipation. This review focuses on the evidence for each of these agents, and the relative indications for each of them
