BACKGROUND፡ Acinetobacter baumannii is a major contributor to nosocomial infections. Extended-spectrum ßlactamase (ESBL)-producing A. baumannii is spreading worldwide. We aimed to determine the frequency of ESBLencoding genes in clinical isolates of A. baumannii and to access their clonal relationship by repetitive extragenic palindromic-PCR (rep-PCR).METHODS: In this descriptive cross-sectional study, 203 isolates of A. baumannii were collected from Qazvin hospitals. The Identification of isolates was performed by standard laboratory methods. To verify ESBL production, all isolates were screened by disk agar diffusion and confirmed by the combined disk method. Subsequently, ESBL-encoding genes were detected by PCR and sequencing. Possible clonal association of ESBL-producing isolates was evaluated using rep-PCR.RESULTS: Two hundred (98.5%) isolates showed reduced susceptibility to one of the antibiotics used in the ESBL screening test, of which 127 isolates (62.6%) produced ESBL. PCR results showed blaOXA-1 (20.5%) was the most prevalent gene followed by blaTEM-1 (20%), blaGES-1 (15.7%), blaCTX-M-15 (7.9%), and blaPER-1(1.6%). Rep-PCR results revealed that ESBL-producing isolates belonged to clones A (85%), B (13.4%), and C (1.6%).CONCLUSION: Our study showed the significant presence of blaOXA-1, blaTEM-1, blaGES-1, blaCTX-M-15, and blaPER-1 genes in ESBLproducing A. baumannii isolates in the studied hospitals. This is the first report on the emergence of blaOXA-1 gene in these isolates in Iran. The use of comprehensive antimicrobial treatment guidelines based on laboratory data and appropriate infection control interventions are essential.

Abstract Objective: To evaluate the phenotypic detection of extended-spectrum beta-lactamase in multidrug-resistant acinetobacter baumannii. Methods: The cross-sectional study was conducted at the Department of Microbiology, Fauji Foundation Hospital, Rawalpindi, Pakistan, from August 2018 to April 2019, after the ethical approval from the Institutional Review Committee. Consecutive Non- probability sampling technique was used, and comprised clinical specimens, including pus, blood, sputum, urine, tracheal tubes and canula double lumen, which were processed using standard protocols. Colonies of acinetobacter baumannii were identified by gram staining and Analytical Profile Index-20E kit. Combination disc method was used for the identification of extended-spectrum beta-lactamse. Clinical and Laboratory Standards Institute guidelines were used for antimicrobial susceptibility. Data was analysed using SPSS 22 and Sample size was calculated by using earlier study with 5 % margin of error and 95 % confidence level. Results: Of the 78 isolates, 58(74.4%) related to females and 20(25.6%) to males. There was no extended-spectrum beta-lactamse producer. Imipenem, meropenem, cefotaxime, ampicillin and ceftazidime showed 100% resistance, while colistin and polymyxin B were sensitive to all strains. The incidence rate was high in samples isolated from tracheal tubes 47(60.3%), followed by pus 21(26.9%). Age was not found to be a significant factor (p>0.05).   Conclusion: Acinetobacter baumannii showed a high resistance to multiple drugs and was not confined to any specific age group. Colistin and polymyxin B were found to be better choices. Continuous...

Abstract Background Laboratory data and computed tomography (CT) have been used during the COVID-19 pandemic, mainly to determine patient prognosis and guide clinical management. The aim of this study was to evaluate the association between CT findings and laboratory data in a cohort of COVID-19 patients. Methods This was an observational cross-sectional study including consecutive patients presenting to the Reggio Emilia (Italy) province emergency rooms for suspected COVID-19 for one month during the outbreak peak, who underwent chest CT scan and laboratory testing at presentation and resulted positive for SARS-CoV-2. Results Included were 866 patients. Total leukocytes, neutrophils, C-reactive protein (CRP), creatinine, AST, ALT and LDH increase with worsening parenchymal involvement; an increase in platelets was appreciable with the highest burden of lung involvement. A decrease in lymphocyte counts paralleled worsening parenchymal extension, along with reduced arterial oxygen partial pressure and saturation. After correcting for parenchymal extension, ground-glass opacities were associated with reduced platelets and increased procalcitonin, consolidation with increased CRP and reduced oxygen saturation. Conclusions Pulmonary lesions induced by SARS-CoV-2 infection were associated with raised inflammatory response, impaired gas exchange and end-organ damage. These data suggest that lung lesions probably exert a central role in COVID-19 pathogenesis and clinical presentation.

Abstract Background Understanding the relationship between breastfeeding (BF) and metabolic syndrome (Mets) is important for maternal long-term health benefits and disease prevention. This study aimed to examine the association between BF and Mets and its components among postmenopausal parous Korean women. Methods This cross-sectional study on 10,356 Korean women used nationally representative data from the KNHANES from 2010 to 2016. Anthropometric, laboratory data and manual BP were measured. A multivariate logistic regression analysis was conducted to examine the association of BF with Mets and its components after adjusting for potential confounding variables. A p-value < 0.05 was to be considered statistically significant. Results Mets was present in 42% of the study participants. The BF group had low household income and education level. The prevalence of Mets in the BF group was higher than that in the non-BF group (42.69% vs. 34.76%, p <  0.001). BF was associated with increased risk of Mets (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 1.18–1.65, p <  0.001). The BF group was at higher risks for diabetes (OR: 1.5, 95%CI: 1.14–1.98), hypertension (OR: 1.32, 95%CI: 1.03–1.68), hypertriglyceridemia (OR: 1.42, 95%CI: 1.02–1.99) and low high-density lipoprotein cholesterol (OR: 1.32, 95%CI: 1.06–1.65). Conclusion In this study, BF did not affect decreasing the prevalence of Mets and its components.

Abstract Aim Diabetic kidney disease (DKD) is a major long-term complication of diabetes mellitus (DM). Given the paucity of data on DKD in Jordan, we aimed to evaluate the prevalence, characteristics and correlates of DKD in Jordanian patients with type 2 DM. Methods This cross-sectional study included 1398 adult patients with type 2 DM who sought medical advice in the endocrinology clinic between March and September 2019. Demographic, clinical and laboratory data were reviewed. DKD was defined as reduced eGFR, and/or albuminuria. Three regression models were constructed to identify factors associated with CKD stages, albuminuria and DKD. Results Overall, 701 (50.14%) patients had DKD, with a median age of 59.71 ± 11.36  years. Older age, high triglycerides, and low high-density lipoprotein were associated with DKD (multivariable odds ratio [OR]: 1.02, 95% confidence interval [CI]: 1.01–1.03, p < 0.01; OR: 1.1, 95% CI: 1.01–1.2; and OR: 0.98, 95% CI: 0.97–0.99, p < 0.01 respectively). Metformin and renin-angiotensin system blockers were negatively associated with albuminuria and chronic kidney disease stages (p < 0.01). Conclusion Our study demonstrated that approximately one half of patients with type 2 DM had DKD. Further studies are necessary to understand this high prevalence and the underlying factors. Future research are needed to assess implementing targeted community-based intervention.

While gastrointestinal disease is common among HIV infected individuals, the prevalence and distribution of ano-rectal pathology has not been well studied in our setting. The objective of this study therefore was to determine the prevalence and determinants of ano-rectal pathology in HIV infected patients attending the Douala General Hospital HIV treatment centre. A hospital-based cross-sectional study was undertaken. We collected socio-demographic, clinical and laboratory data using a structured questionnaire and patients’ files. Each study participant had a full physical and ano-rectal examination. We further studied factors associated with having at least one ano-rectal lesion by logistic regression reporting odds ratios (ORs) and their 95% confidence intervals (CI). We included 390 HIV infected patients. The mean age was 41 (SD: 8) years and 48% were men. Median duration since HIV diagnosis was 3 (interquartile range: 2–5) years and median CD4 cell count was 411 (interquartile range: 234–601) cells/mm3. Prevalence of ano-rectal pathology was 22.8% (95% CI: 18.7–27.3). Hemorrhoids and proctitis were most common lesions found; each in 10% of patients. From multivariate logistic regression, factors associated with ano-rectal pathology were CD4 < 350 cells/ml (OR: 2.1, 95% CI: 1.1–4.2), not on highly active antiretroviral therapy (OR: 2.2, 95% CI: 1.1–4.6), inpatient (OR: 2.3, 95% CI: 1.2–4.3), ano-rectal intercourse (OR: 5.0, 95% CI: 1.7–15.1), and more than one sexual partner (OR: 2.4, 95% CI: 1.3–4.2). Ano-rectal pathology is common amongst HIV infected patients. Care givers should actively investigate and treat them as this will improve the quality of life of people living with HIV/AIDS.

SUMMARY OBJECTIVE: HIV-related mortality is still high, especially in developed countries. The aim of this study is to investigate factors associated to death in HIV-infected patients. METHODS: This is a cross-sectional study with all HIV adult patients admitted to a tertiary infectious diseases hospital in Fortaleza, Northeast Brazil, from January 2013 to December 2014. Patients were divided into two groups: survivors and non-survivors. Demo-graphical, clinical and laboratory data were compared and a logistic regression was performed in order to investigate risk factors for death. P values ≤0.05 were considered statistically significant. RESULTS: A total of 200 patients with mean age of 39 years were including in the study, 69.5% males. Fifteen patients (7.5%) died. Non-survivors presented a higher percentage of males (93.3 vs. 67.3%, p = 0.037). Non-survivors presented AKI (73.3 vs. 10.3%, p < 0.001), liver dysfunction (33.3 vs. 11.5, p = 0.031), dyspnea (73.3 vs. 33.0%, p = 0.002) and disorientation (33.3 vs. 12.4%, p = 0.025) more frequently. Non-survivors also had higher levels of urea (73.8 ± 52.7vs. 36.1 ± 29.1 mg/dL, p < 0.001), creatinine (1.98 ± 1.65 vs. 1.05 ± 1.07 mg/dL, p < 0.001), aspartate aminotransferase (130.8 vs. 84.8 U/L, p = 0.03), alanine aminotransferase (115.6 vs. 85.4 U/L, p = 0.045) and lactate dehydrogenase (LDH) (1208 vs. 608 U/L, p = 0.012), as well as lower levels of bicarbonate (18.0 ± 4.7 vs. 21.6 ± 4.6 mEq/L, p = 0.016) and PCO2 (27.8 ± 7.7 vs. 33.0 ± 9.3 mmHg, p = 0.05). In multivariate analysis, disorientation (p = 0.035, OR = 5.523, 95%CI = 1.130 – 26.998), dyspnoea (p = 0.046, OR = 4.064, 95%CI = 1.028 – 16.073), AKI (p < 0.001, OR = 18.045, 95%CI = 4.308 – 75.596) and disseminated histoplasmosis (p = 0.016, OR = 12.696, 95%CI = 1.618 – 99.646) and LDH > 1000 U/L (p = 0.038, OR = 4.854, 95%CI = 1.093 – 21.739) were risk factors for death.]CONCLUSION: AKI and disseminated histoplasmosis (DH) were the main risk factors for death in the studied population. Neurologic and respiratory impairment as well as higher levels of LDH also increased mortality in HIV-infected patients.

<p><strong>INTRODUCTION</strong><strong>:</strong> In dentistry, medicine often prescribed to relieve pain and remove infections .Therefore, wrong prescription can lead to a range of problems including lack of pain, antimicrobial treatment failure and the development of resistance to antibiotics.</p> <p><strong>MATERIALS &amp; METHODS</strong><strong>:</strong> In this cross-sectional study, the aim was to evaluate the common errors in written prescriptions by general dentists in Kermanshah in 2014. Dentists received a questionnaire describing five hypothetical patient and the appropriate prescription for the patient in question was asked. Information about age, gender, work experience and the admission in university was collected. The frequency of errors in prescriptions was determined. Data by SPSS 20statistical software and using statistical t-test, chi-square and Pearson correlation were analyzed (0.05&gt; P).</p> <p><strong>RESULTS</strong><strong>: </strong>A total of 180 dentists (62.6% male and 37.4% female) with a mean age of 8.23 ± 39.199 participated in this study. Prescription errors include the wrong in pharmaceutical form (11%), not having to write therapeutic dose (13%), writing wrong dose (14%), typos (15%), error prescription (23%) and writing wrong number of drugs (24%).The most frequent errors in the administration of antiviral drugs (31%) and later stages of antifungal drugs (30%), analgesics (23%) and antibiotics (16%) was observed. Males dentists compared with females dentists showed more frequent errors (P=0.046). Error frequency among dentists with a long work history (P&gt;0.001) and the acceptance in the university except for the entrance examination (P=0.041) had a statistically significant relationship.</p> <p><strong>CONCLUSION</strong><strong>:</strong> This study showed that the written prescription by general dentists examined contained significant errors and improve prescribing through continuing education of dentists is essential.</p>

Quality Of Prescribing

Objective: The drug policy of Mali is based on the concept of essential generic drugs. The adoption of generic drugs in a program is often accompanied by irrational use of these drugs precisely because of the availability of these drugs. Thus, this study was initiated to assess the quality of prescribing and dispensing drugs in Mali. Methods: This is a descriptive cross-sectional study was conducted from 2004 to 2013, the survey was conducted in 20 primary health centers and 20 private pharmacies in three regions of the country. In each of these structures, 30 prescriptions filled at the time of the survey were collected. Results: The average number of drugs per prescription was 3.0 ± 1.3 and 2.4 ± 1.2, respectively, in the public and private sectors. Prescription of drugs under international name was 91.6% in the public sector and 37.2% in the private sector. The public sector prescribed 33.7% of injectable drug against 16.2% in the private sector (p <0.001). The average cost of a prescription was lower in the public sector (3415.3 FCFA or 5.21euros) than in the private sector (7111 FCFA or 10.85 euros).Conclusion: Generic drugs are commonly used in the public, but much less in the private sector. The treatment guidelines are already available, should be introduced interactively to medical practitioners, through visits and intensive supervision by more experienced managers in the hierarchy, it would be likely to improve the quality of prescribing practitioners.

Background : Increased multidrug resistance of extended-spectrum beta-lactamases (ESBLs) compromises the efficacy of treatment of urinary tract infections. Objective : The objective of this study is to determine the prevalence of ESBL-producing uropathogens from hospitalized patients with chronic pyelonephritis and to identify the presence of genes involved in the resistance. Methods : A cross-sectional study of 105 patients with chronic pyelonephritis, treated in Kharkiv City Clinical Emergency Hospital, Ukraine was carried. Bacterial isolates were collected, antimicrobial susceptibility of isolates was determined by the Kirby Bauer disk diffusion method and screening for the presence of blaSHV, blaTEM, blaCTX-M ESBL genes was performed by polymerase chain reaction. Results : 84 (80%) patients had positive urine cultures. Eschеrichia coli wаs the most common microorganism isolated. Among them, 29 (25.2%) were found to be ESBL producers. Out of 53 E. coli isolates, 10 (18.9%), 4 (7.5%) and 6 (11.3%) were identified to carry bla(TEM), bla(SHV) and bla(CTX-M) beta-lactamase genes, respectively. The highest resistance was observed against ampicillin (75.9%), ciprofloxacin (48.3%), levofloxacin (41.4%) and gentamicin (41.4%). Beside this, only meropenem (96.6% susceptibility), nitroxolinum (86.2%) and fosfomycin (72.4%) exhibited a good enough activity against ESBLs-producing urinary strains. Conclusion : Isоlation and detеction of ESBL-prоducing strаins are еssential fоr the sеlection оf the mоst effеctive antibiоtic for the empiric trеatment.
