Hidden Costs of Hospital-Based Delivery Among Women Using Public Hospitals in Bale Zone, Southeast Ethiopia

Background: The Ethiopian health care system since 2005 has encouraged safe enhanced obstetrical care. However, hospital delivery has remained expensive for poor households due to hidden costs. Hidden costs are the costs that are not accounted for in direct hospital costs. The aim of this study was to estimate the hidden costs of institutional delivery and to identify its associated factors. Methods: A health facility–based cross-sectional study was conducted in the Bale zone from August 13 to September 2, 2018. Exit interviews were conducted among women who gave birth at the selected hospitals. A total of 390 women from 1 referral hospital and 2 general hospitals were included into the study. Systematic sampling technique was used to select study participants. Multiple linear regression analysis was done to identify the predictors of the hidden cost of institutional delivery. Result: The median hidden cost of institutional delivery was 877.5 ETB (32.03 USD). The median of the direct medical cost of normal delivery was 280 ETB (10.21 USD) while the direct nonmedical cost was 230 ETB (8.40 USD). For cesarean section, the median direct medical cost was 292 ETB (10.66 USD) while indirect costs were 591 ETB (21.60 USD). For forceps delivery, the direct medical cost was 362 ETB (13.21 USD) while the direct medical cost was 360 (13.14 USD). Distance of household from the hospital (β = 0.165), length of stay at the hospital (β = 0.050), mode of delivery (β = −0.067), and family monthly income (β = 0.201) were the explanatory variables significantly associated with the hidden cost. Conclusion: This study showed hidden cost of facility-based delivery was high. Distance, length of stay, income, and mode of delivery were the predictor of hidden cost. Ethiopian health care system should consider the hidden costs for pregnant women and their families.
X‐ray crystallographic structure of BshB, the zinc‐dependent deacetylase involved in bacillithiol biosynthesis

Many gram‐positive bacteria produce bacillithiol to aid in the maintenance of redox homeostasis and degradation of toxic compounds, including the antibiotic fosfomycin. Bacillithiol is produced via a three‐enzyme pathway that includes the action of the zinc‐dependent deacetylase BshB. Previous studies identified conserved aspartate and histidine residues within the active site that are involved in metal binding and catalysis, but the enzymatic mechanism is not fully understood. Here we report two X‐ray crystallographic structures of BshB from Bacillus subtilis that provide insight into the BshB catalytic mechanism.
Characterizing impulsivity and resting-state functional connectivity in normal-weight binge eaters.

OBJECTIVE Binge eating is characterized by episodes of uncontrolled eating, within discrete periods of time. Although it is usually described in obese individuals or as a symptom of Binge Eating Disorder (BED), this behavior can also occur in the normal-weight (NW) population. An interesting premise suggests that impulsivity might contribute to the onset of binge eating and the progression toward weight gain. Drawing upon this evidence, here we explored impulsivity in NW individuals reporting binge-eating episodes through a functional connectivity approach. We hypothesized that, even in the absence of an eating disorder, NW binge eaters would be characterized by connectivity pattern changes in corticostriatal regions implicated in impulsivity, similarly to the results described in BED individuals. METHODS A resting-state functional magnetic resonance imaging study tested 39 NW men and women, with and without binge eating (binge eaters, BE and non-BE). Brain functional connectivity was explored by means of graph theoretic centrality measures and traditional seed-based analysis; trait impulsivity was assessed with self-report questionnaires. RESULTS The BE group was characterized by a higher degree of trait impulsivity. Brain functional connectivity measures revealed lower degree centrality within the right middle frontal gyrus, left insula/putamen and left temporoparietal regions and a lower functional connectivity between the right middle frontal gyrus and right insula in the BE group. DISCUSSION The results support previous evidence on BED of altered functional connectivity and higher impulsivity at the roots of overeating behavior, but further extend this concept excluding any potential confounding effect exerted by the weight status.
Hormones and oxidative stress: an overview

Abstract In aerobes, oxygen is essential for maintenance of life. However, incomplete reduction of oxygen leads to generation of reactive oxygen species. These oxidants oxidise biological macromolecules present in their vicinity and thereby impair cellular functions causing oxidative stress (OS). Aerobes have evolved both enzymatic and nonenzymatic antioxidant defences to protect themselves from OS. Although hormones as means of biological coordination involve in regulation of physiological activities of tissues by regulating metabolism, any change in their normal titre leads to pathophysiological states. While, hormones such as melatonin, insulin, oestrogen, progesterone display antioxidant features, thyroid hormone, corticosteroids and catecholamines elicit free radical generation and OS, and the role of testosterone in inducing OS is debateable. This review is an attempt to understand the impact of free radical generation and cross talk between the hormones modulating antioxidant defence system under various pathophysiological conditions.
The Association of MTHFR C677T and MTR A2756G Gene Polymorphisms With the Risk of Systemic Lupus Erythematosus

S ystemic lupus erythematosus (SLE) is a multiorgan autoimmune disease, and an interplay between genetic susceptibility and environmental factors are central to its pathophysiology. Epigenetic alteration with DNA hypomethylation in immune cells plays a crucial role in the pathogenesis of SLE, and the process of DNAmethylation is dependent on the cellular metabolism of folic acid.Methylenetetrahydrofolate reductase (MTHFR) is themain enzyme in folic acid metabolism, and it catalyzes the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, which is a necessary substrate for remethylation of homocysteine to methionine. Two common MTHFR gene polymorphisms, C677T and A1298C, are linked to folate deficiency, hyperhomocysteinemia, and DNA hypomethylation. Besides, methionine synthase encoded by MTR gene promotes methyl group transfer from 5-methyltetrahydrofolate to homocysteine to produce methionine, which is then transformed into S-adenosylmethionine to donate a methyl group for DNA methyltransferases. Hypomethylation of genomic DNA was also found to be associated with MTR A2756G gene polymorphisms. Previous studies have revealed conflicting results regarding the role ofMTHFR andMTR gene polymorphisms in SLE. Therefore, we aimed to elucidate this issue with this systematic review and meta-analysis. METHODS Systematic search for all studies published before June 20, 2019 were performed in the databases of Pubmed, Embase, Web of Science, andCochraneLibrary, andwe included case-control studies that compared the prevalence of MTHFR or MTR gene polymorphisms in SLE patients with those in controls (PROSPERO Identifier: CRD 42019144541). The search strategy included the following keywords: “methylenetetrahydrofolate reductase or MTHFR” or “methionine synthase orMTR” combined with “systemic lupus erythematosus or SLE. ”We excluded review articles, case series, and conference abstracts, and articles published in languages other than English were considered after appropriate translation. The quality of each study was evaluated using the Newcastle-Ottawa Scale. A random-effects model was used for the meta-analysis. We presented the results as odds ratios with 95% confidence intervals.
Role of Hypoalbuminemia as an Independent Predictor of 30-Day Postoperative Complications Following Surgical Fixation of Ankle Fractures

Background: Malnutrition is known to be negatively associated with outcomes after multiple orthopedic procedures. We hypothesized that admission albumin levels, as a marker for malnutrition, would correlate with postoperative outcomes. The purpose of this study was to investigate this relationship following surgery for ankle fracture. Methods: This is a retrospective cohort study of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Patients undergoing operative fixation of an ankle fracture were identified. A total of 6138 patients with albumin available for analysis were identified. Baseline patient information, preoperative serum albumin levels, 30-day postoperative complications, readmission, reoperation, and length of stay data were then collected. Poisson regression with robust error variance was performed to assess the effect of preoperative serum albumin level on postoperative outcomes. Results: The mean albumin level was 3.86 g/dL and 20.3% (1246/6138) of patients with available albumin levels were hypoalbuminemic. Multivariate analysis revealed that an albumin level <3.5 g/dL was an independent risk factor for complications (relative risk [RR], 1.42; 95% confidence interval [CI], 1.13-1.78; P = .002) and readmission (RR, 1.54; 95% CI, 1.13-2.08; P = .006). Additionally, when analyzed as a continuous variable, albumin level was negatively correlated with risk of mortality (RR, 0.37; 95% CI, 0.19-0.72; P = .003). Patients with hypoalbuminemia also had significantly longer lengths of stay (4.5 vs 2.1 days; P < .001). Conclusion: While complication rates after fixation of ankle fractures remain low, hypoalbuminemia was a predictor of postoperative course. Malnutrition, therefore, may help inform the decision between surgical and conservative management of patients with ankle fractures potentially amenable to nonoperative management. Additionally, hypoalbuminemia should trigger heightened awareness and prophylactic therapy where appropriate. Level of Evidence: Level III, comparative study.
Nonalcoholic Fatty Pancreas Disease: Clinical Consequences

Metabolic syndrome and its components such as obesity, hypertriglyceridemia, type-2 diabetes mellitus (DM-T2), and arterial hypertension are unequivocally serious problems for every society. This is especially true in economically developed countries where the imbalance in lifestyle between caloric intake and caloric output still gets greater and greater. This fact is not only a concern for the adult population but for children as well. However, metabolic syndrome does not only affect society and health in regards to cardiovascular diseases, it significantly concerns gastroenterology where it is classified as nonalcoholic fatty pancreas disease (NAFPD). The data gained from several trials show that the prevalence of NAFDP is 33% (95% CI 24–41%). When it comes to the diagnostic procedures concerning the presence of pancreatic fat, a whole spectrum of suitable methods are recommended. Probably, the most exact method is the use of magnetic resonance imaging. However, for common clinical practice, the abdominal sonographic examination based on the comparison of the pancreatic parenchymatous echogenity versus renal or hepatic echogenity is used. The clinical consequences of pancreatic steatosis and steatopancreatitis are significant. These diseases are connected with DM-T2 and insulin resistance. In recent years, changes of exocrine pancreatic function, particularly its decrease, have also been described. It is known that there is a close correlation between NAFPD and nonalcoholic hepatic steatosis and also with the increased thickness of aortic intima-media. There is also an important relationship between NAFPD and pancreatic carcinoma. Pancreatic steatosis, and especially its NAFPD form, is a serious state which can be treatable by the possible effective management of metabolic syndrome parameters, including obesity.
Systematic review and network meta-analysis of the efficacy and safety of glycopyrrolate/formoterol fumarate metered dose inhaler in comparison with other long-acting muscarinic antagonist/long-acting β2-agonist fixed-dose combinations in COPD

Background: Dual bronchodilation with a long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) fixed-dose combination (FDC) is an established treatment strategy for chronic obstructive pulmonary disease (COPD). The relative efficacy and safety of glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI 18/9.6 μg) in patients with moderate-to-very severe COPD, compared with other licensed LAMA/LABA FDCs, was investigated using an integrated Bayesian network meta-analysis (NMA). Methods: A systematic literature review and subsequent screening process identified randomized controlled trials of ⩾10 weeks’ duration that enrolled patients aged ⩾40 years with moderate-to-very severe COPD and included at least one LAMA/LABA FDC or open LAMA + LABA treatment arm. NMAs were conducted for outcomes including change from baseline in forced expiratory volume in 1 s (FEV1), St George’s Respiratory Questionnaire (SGRQ), and transition dyspnea index (TDI) parameters, annualized rate of exacerbations, use of rescue medication, adverse events, and all-cause withdrawals. Meta-regression and sensitivity analyses accounted for heterogeneity across studies. Results: In total, 29 studies including 34,617 patients contributed to the NMA for efficacy or safety outcomes at week 24 or exacerbations. For all LAMA/LABA FDCs with data available, significantly greater improvements in FEV1 [trough, peak, and area under the curve (AUC)0–4], SGRQ total score and TDI focal score at week 24, and annualized rate of moderate-to-severe exacerbations, were observed versus placebo. Where indirect comparisons were possible, differences between GFF MDI and other LAMA/LABA FDCs were small relative to established margins of clinical relevance, and not statistically significant. The safety and tolerability profile of GFF MDI was consistent with other LAMA/LABA FDCs and placebo. The results of the meta-regression were generally similar to the base case. Conclusions: GFF MDI demonstrated comparable efficacy and safety outcomes to other LAMA/LABA FDCs. Personalization of treatment choice within the class on the basis of other factors such as patient preference may be appropriate.
Integron related resistance in new emerged Staphylococcus lugdunensis infection in burn patients.

Staphylococcus lugdunensis (SL) is a coagulase negative staphylococcus species (CNS) that may cause various infections with unusual severity. In spite of the administration of various antibiotics, infections caused by such bacteria are become resistant significantly. Transmission of antibiotic resistance genes, especially by Integron structures, exacerbates the prevalence of resistant strains. To investigate the antibiotic susceptibility pattern of S. lugdunensis as a new emergence in burns, by presence of integron classes (I, II, III) was performed in recent study. Sampling for this study was carried out over a period of 13 months (January 2017 to February 2018) from Amir-Al-Momenin burn center of southwest of Iran, affiliated with Shiraz University of Medical Sciences. Twenty eight isolates of S. lugdunensis were confirmed by phenotypic tests. Presence of Integron classes was evaluated by PCR technique and specific primers. The majority of studied infectious agents were seen in ICU with 28.57%. The prevalence of class I and II integrons was 7 (25.00%) and 2 (7.14%) respectively in SL isolates while no integron III was found. No significant association was seen between antibiotic resistance and the present Integrons (p- value >0.05). Since the prevalence of S. lugdunensis strains as a new emergence infection is increasing in clinical settings especially burns, preventing drug resistance in these isolates is inevitable. So knowing the epidemiology pattern of new emerging infections and their resistant pattern is very helpful in infection control and save hospitalized patients life.
Comparable stx2a expression and phage production levels between Shiga toxin‐producing Escherichia coli strains from human and bovine origin

Shiga toxin‐producing Escherichia coli (STEC) can cause diarrhoea and severe diseases in humans, such as haemolytic uraemic syndrome. STEC virulence is considered to correlate with the amount of Shiga toxins (Stx) produced, especially Stx2, whose subtype Stx2a is most frequently associated with high virulence. Stx are encoded in prophages, which play an important role in STEC pathogenesis. The aim of this study was to evaluate stx2a expression levels and Stx2a phage production using qPCR and the double‐agar‐layer method in 29 STEC strains, corresponding to serotypes O26:H11 (6), O91:H21 (1), O145:H‐ (11) and O157:H7 (11), isolated from cattle and humans. Results were then tested for possible associations with serotype, origin or some genetic features. We observed heterogeneous levels of stx2a expression and Stx2a phage production. However, statistical comparisons identified a higher stx2a expression in response to mitomycin C in strains isolated from cattle than in those from humans. At the same time, compared to stx2a/stx2c strains, stx2a strains showed a higher increase in phage production under induced conditions. Notably, most of the strains studied, regardless of serotype and origin, carried inducible Stx2a phages and evidenced expression of stx2a that increased along with phage production levels under induced conditions.
Toxoplasma gondii in beef consumed in France: regional variation in seroprevalence and parasite isolation

In France, the consumption of cattle and sheep meat appears to be a risk factor for infection of pregnant women with Toxoplasma gondii. Several nation-wide surveys in France have investigated the prevalence of T. gondii in sheep and pig meat, but little is known at present about the prevalence of the parasite in beef. The main objective of the present cross-sectional survey was to estimate the seroprevalence of T. gondii infection in beef consumed in France. A secondary objective was to attempt to isolate T. gondii from cattle tissues and to study the geographical and age variations of this seroprevalence. The overall estimate of seroprevalence of T. gondii in bovine carcasses (n = 2912), for a threshold of 1:6 was 17.38%. A strong age effect was observed (p < 0.0001) with a seroprevalence of 5.34% for calves (<8 months) and 23.12% for adults (>8 months). Seroprevalence estimates given by area of birth and area of slaughtering for adults showed that the areas with the highest seroprevalence were not the same between these two variables. Only two strains, corresponding to genotype II, were isolated from heart samples, indicating that there is a limited risk of human infection with T. gondii, which needs to be correlated with the food habit of consuming raw or undercook (bleu or saignant) beef. However, new questions have emerged, especially concerning the isolation of parasites from beef and the precise role of bovines, generally described as poor hosts for T. gondii, in human infection.
5ʹUTR polymorphism in the serotonergic receptor HTR3A gene is differently associated with striatal Dopamine D2/D3 receptor availability in the right putamen in Fibromyalgia patients and healthy controls—Preliminary evidence

Extensive literature has investigated the role of serotonin (5‐HT) in the control of the central dopamine (DA) systems, and their dysfunction in the pathological conditions. 5‐HT stimulates the local DA release in striatal regions via activation of various receptors including serotonin receptor‐3 (5‐HT3). Several studies have related polymorphisms (SNPs) in the serotonin receptor‐3 (HTR3) genes to be associated with the pain modulation and endogenous pain suppression. A few studies suggested a functional role of 5ʹUTR SNP in the serotonergic receptor HTR3A gene (rs1062613) in the development of the chronic pain and Fibromyalgia syndrome (FMS) in particular. Here, we investigated the effect of a 5ʹUTR SNP in the serotonergic receptor HTR3A gene (rs1062613) on striatal dopamine D2/D3 receptor (DRD2) availability and reward‐associated DA release in response to unpredictable monetary rewards in 23 women with FMS and 17 age‐matched healthy female controls. Furthermore, we aimed to examine if SNP rs1062613 is associated with thermal pain and pain tolerance thresholds.
Cognitive Functions in Adults Receiving Cochlear Implants: Predictors of Speech Recognition and Changes After Implantation.

HYPOTHESES Significant variability in speech recognition outcomes is consistently observed in adults who receive cochlear implants (CIs), some of which may be attributable to cognitive functions. Two hypotheses were tested: 1) preoperative cognitive skills assessed visually would predict postoperative speech recognition at 6 months after CI; and 2) cochlear implantation would result in benefits to cognitive processes at 6 months. BACKGROUND Several executive functioning tasks have been identified as contributors to speech recognition in adults with hearing loss. There is also mounting evidence that cochlear implantation can improve cognitive functioning. This study examined whether preoperative cognitive functions would predict speech recognition after implantation, and whether cognitive skills would improve as a result of CI intervention. METHODS Nineteen post-lingually deafened adult CI candidates were tested preoperatively using a visual battery of tests to assess working memory (WM), processing speed, inhibition-concentration, and nonverbal reasoning. Six months post-implantation, participants were assessed with a battery of word and sentence recognition measures and cognitive tests were repeated. RESULTS Multiple speech measures after 6 months of CI use were correlated with preoperative visual WM (symbol span task) and inhibition ability (stroop incongruent task) with moderate-to-large effect sizes. Small-to-large effect size improvements in visual WM, concentration, and inhibition tasks were found from pre- to post-CI. Patients with lower baseline cognitive abilities improved the most after implantation. CONCLUSIONS Findings provide evidence that preoperative cognitive factors contribute to speech recognition outcomes for adult CI users, and support the premise that implantation may lead to improvements in some cognitive domains.
Race and Ethnicity Gaps in Global Hidradenitis Suppurativa Clinical Trials

Background: Hidradenitis suppurativa (HS) is an often-debilitating disease characterized by chronic and recurrent painful nodules, abscesses, and sinus tracts affecting the intertriginous areas. Despite evidence in the literature of varying prevalence of HS among different racial and ethnic groups, no studies have evaluated the overall generalizability of clinical trial results considering the increased prevalence of HS among African American populations. Additionally, there is a paucity of data exploring the distribution of race and ethnicity in randomized controlled trials (RCTs) for HS. The goal of this analysis is to explore the distribution of race and ethnicity in recent HS RCTs. Summary: Using ClinicalTrials.gov and PubMed, race and ethnicity demographics were extracted from phase II and III trials published from 2000 to August 2019. Fifteen trials were included and among these trials 669 (68.0%) participants were Caucasian and 138 (14.0%) were of African descent. Asians, American Indian or Alaskan Natives, and Native Hawaiian or other Pacific Islanders comprised 29 (2.9%), 3 (0.3%), and 1 (0.1%) participant respectively. Only 15 participants were reported as Hispanic as only three trials reported ethnicity data. The remaining 144 (14.6%) participants were recorded as “other/unspecified” (36 self-identified, 108 lacked race reporting). None of the trials included sub-analysis of treatment efficacy based on race or ethnicity.
