Role of serum allograft inflammatory factor-1 (AIF-1) in Egyptian type 2 diabetic patients

Background. Diabetes mellitus (DM) is a powerful and independent risk factor for cardiovascular disease. The atherosclerosis process in diabetes is indistinguishable from that of the nondiabetic population, but it begins earlier and is often more extensive and more severe. AIF-1 promotes chemotaxis, spreading and migration of macrophages and vascular smooth muscle cells (VSMCs) which suggest a role of AIF-1 in the atherosclerotic plaque formation. Thus, this study determines the role of AIF-1 in the Egyptian type 2 diabetic patients. Results. The level of AIF-1 was significantly higher in the type 2 diabetic group when compared to the control group (p = 0.000). In type 2 diabetic patients group, there was a significant positive correlation between CIMT and AIF-1 (r = 0.468, p = 0.000). In addition to the positive correlation between CIMT and AIF-1, CIMT in regression model analysis was significantly positive contributing to the outcome variable (AIF-1) (p < 0.05), denoting the possible role of elevated serum AIF-1 level in atherosclerotic process with further studies on larger scale needed

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10&nbsp;years; 78.2% included were male with a median age of 37&nbsp;years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Pooled analysis of who surgical safety checklist use and mortality after emergency laparotomy

Background: The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods: In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results: Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89⋅6 per cent) compared with that in countries with a middle (753 of 1242, 60⋅6 per cent; odds ratio (OR) 0⋅17, 95 per cent c.i. 0⋅14 to 0⋅21, P &lt; 0⋅001) or low (363 of 860, 42⋅2 percent; OR 0⋅08, 0⋅07 to 0⋅10, P &lt; 0⋅001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference −9⋅4 (95 per cent c.i. −11⋅9 to −6⋅9) per cent; P &lt; 0⋅001), but the relationship was reversed in low-HDI countries (+12⋅1 (+7⋅0 to +17⋅3) per cent; P &lt; 0⋅001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0⋅60, 0⋅50 to 0⋅73; P &lt; 0⋅001). The greatest absolute benefit was seen for emergency surgery in low-and middle-HDI countries. Conclusion: Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries

Global economic burden of unmet surgical need for appendicitis

Background: There is a substantial gap in provision of adequate surgical care in many low-and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods: Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results: Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion: For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially

Global variation in anastomosis and end colostomy formation following left-sided colorectal resection

Background End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model. Results In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001). Conclusion Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone

Insulin Resistance and Hepatitis C Virus-Associated Subclinical Inflammation Are Hidden Causes of Pruritus in Egyptian Hemodialysis Patients: A Multicenter Prospective Observational Study

&lt;b&gt;&lt;i&gt;Background:&lt;/i&gt;&lt;/b&gt; Pruritus is one of the most common and disturbing symptoms in hemodialysis (HD) patients. The pathogenesis of pruritus in HD patients is multifactorial; however, a little progress in understanding this pathogenesis has been achieved. &lt;b&gt;&lt;i&gt;Objectives:&lt;/i&gt;&lt;/b&gt; To evaluate the frequency and risk factors of pruritus among HD patients in Dakahlia, Egypt. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; A total of 193 patients from 4 HD centers were included in this study. Pruritus intensity was assessed by visual analog scale. All patients were assessed by clinical and laboratory parameters, such as age, sex, duration of dialysis, dialysis adequacy, urea, calcium, phosphorus, parathyroid hormone, fasting insulin, fasting sugar, HOMA-IR, serum ferritin, high-sensitive C-reactive protein (hs-CRP) and hemoglobin. They were also investigated for hepatitis C virus (HCV) infection by HCV enzyme-linked immunosorbent assay, HCV-PCR for plasma and buffy coat for further detection of occult HCV infection. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; Male gender, dialysis duration, inadequate dialysis, anemia, high ferritin, hyperphosphatemia, hypocalcemia, hs-CRP, and insulin resistance were characteristic features in pruritic patients (&lt;i&gt;p&lt;/i&gt; = 0.01, 0.006, 0.0001, 0.047, 0.01, 0.0001, 0.024, 0.000, and 0.0001, respectively). Significant positive correlations were found between pruritus score and each of age (&lt;i&gt;p&lt;/i&gt; = 0.002, &lt;i&gt;r&lt;/i&gt; = 0.222), duration of dialysis (&lt;i&gt;p&lt;/i&gt; = 0.03, &lt;i&gt;r&lt;/i&gt; = 0.151), serum ferritin (&lt;i&gt;p&lt;/i&gt; = 0.001, &lt;i&gt;r&lt;/i&gt; = 0.213), serum phosphorus (&lt;i&gt;p&lt;/i&gt; = 0.0001, &lt;i&gt;r&lt;/i&gt; = 0.59), fasting insulin (&lt;i&gt;p&lt;/i&gt; = 0.001, &lt;i&gt;r&lt;/i&gt;= 0.273), and HOMA-IR (&lt;i&gt;p&lt;/i&gt; = 0.0001, &lt;i&gt;r&lt;/i&gt; = 0.349), while there was a negative correlation with Kt/V (&lt;i&gt;p&lt;/i&gt;= 0.0001, &lt;i&gt;r&lt;/i&gt; = –0.459). Linear multivariate regression analysis showed that age, duration of dialysis, serum phosphorus, Kt/v, and hs-CRP were good predictors for pruritic score in HD patients. All HCV-infected patients (who were positive for both plasma and buffy coat HCV-PCR) had pruritus with ­significantly higher pruritus score than non-infected patients (&lt;i&gt;p&lt;/i&gt; = 0.009), they also showed significantly higher fasting insulin, HOMA-IR, and hs-CRP levels (&lt;i&gt;p&lt;/i&gt; = 0.0001). &lt;b&gt;&lt;i&gt;Conclusions:&lt;/i&gt;&lt;/b&gt; Uremic pruritus (UP) is a serious problem in HD patients. hs-CRP, male gender, dialysis duration, insulin resistance, dialysis inadequacy, and hyperphosphatemia are positively correlated with the intensity of UP. HCV infection is associated with severe UP, insulin resistance, and inflammation.</jats:p

Ocena znaczenia surowiczego stężenia czynnika zapalnego przeszczepu allogenicznego typu 1 (AIF-1) u egipskich chorych na cukrzycę typu 2

Wstęp. Cukrzyca jest silnym i niezależnym czynnikiem ryzyka chorób układu sercowo-naczyniowego. Proces rozwoju miażdżycy u chorych na cukrzycę przebiega podobnie jak u osób wolnych od tej choroby, jednak zaczyna się wcześniej, a zmiany są często bardziej rozległe i nasilone. Czynnik zapalny przeszczepu allogenicznego typu 1 (AIF-1) stymuluje chemotaksję i migrację makrofagów i komórek mięśniówki gładkiej naczyń, co sugeruje udział tego czynnika w powstawaniu blaszki miażdżycowej. Celem badania było ustalenie roli AIF-1 u egipskich chorych na cukrzycę typu 2. Wyniki. Stężenie AIF-1 było istotnie wyższe w grupie chorych na cukrzycę typu 2 niż w grupie kontrolnej (p = 0,000). U chorych na cukrzycę stwierdzono dodatnią korelację między wartościami grubości kompleksu błony środkowej i wewnętrznej tętnicy szyjnej (CIMT) a stężeniem AIF-1 (r = 0,468; p = 0,000). Ponadto, w modelu regresji wartości CIMT były istotnie dodatnio związane ze zmienną wynikową (AIF-1) (p &lt; 0,05), co wskazuje na potencjalną rolę zwiększonego stężenia AIF-1 w surowicy w rozwoju miażdżycy. Wnioski. Konieczne są jednak dalsze badania, prowadzone na większą skalę
