Evaluation of the Response Rates of Hospitals in the Prevention and Control of COVID-19 in Hamadan Province of Iran.

The COVID-19 pandemic has challenged the capacity of health systems in various countries. This study was designed to evaluate the response rates of hospitals in the prevention and control of COVID-19 in Hamadan province, Iran. In this cross-sectional study, all 20 hospitals in Hamadan province were monitored in February 2020. The instrument used in this study was the WHO checklist, entitled "Infection prevention and control health-care facility response for COVID-19." In each hospital, the hospital infection control officials completed the checklists under the supervision of the hospital managers and were then provided to the project manager. Data analyzed by SPSS 22 software. There were 3482 hospital beds (the average beds of each hospital was 174) in the studied hospitals. Of 15 055 patients admitted to all hospitals, 2196 (14.6%) individuals were COVID-19 patients. The total average score obtained from the checklist was 62.25. Among 7 domains studied, the lowest scores belonged to 2 domains of "infrastructure and equipment" and "patient screening and triage." The scores of domains "IPC programs" and "visitors" were significantly higher in hospitals with ICU beds than other hospitals (P-value = .03 in both domains). A comparison between university-teaching hospitals with other hospitals and those in Hamadan city with other cities revealed no significant differences in any of the domains. The mean response rate (62.25) of hospitals in terms of COVID-19 in Hamadan province indicates their relative readiness to prevent and control the COVID19 pandemic. The shortage of infrastructure and equipment and screening and triage problems of patients were the main challenges of hospitals in managing the COVID-19 pandemic in Hamadan province, Iran.

Effect of TQM educational interventions on the management policy standard of health promoting hospitals.

The purpose of this study was to manage total quality management (TQM) to increase the standard of management policy and contribute to achieve the standards for health promotion hospitals (HPHs). This was a quasi-experimental intervention study. A total of 35 managers participated in this study were selected in the census. Based on the TQM components, educational items were provided as lectures, posters and pamphlets. The TQM questionnaire and HPHs checklist used to collect data in three different periods: before the interventions, immediately after the interventions and 3 months after the interventions (follow-up). The data analysis was done by means of SPSS software (version 23). The results showed that the average difference of the components of the qualitative groups (p < 0.001), education (p = 0.004), evaluation and feedback (p < 0.001), customer-orientation (p < 0.001), suggestion system (p = 0.024), leadership commitment (p < 0.001) was significant over the three periods. Excluding the employment status before the educational intervention (p = 0.002), there was no significant relationship between the demographic characteristics and mean score of TQM (p > 0.05). Based on the findings of this study, the educational interventions had a positive effect on quality management and management policy. Therefore, educational interventions should be accompanied by changes in the culture and management policies of the hospital to meet HPH standards.

Effects of Vitamin D Supplementation on Recurrence of Nasal Polyposis after Endoscopic Sinus Surgery.

INTRODUCTION: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a relatively common disease with serious impacts on patient quality of life. Recurrence of polyps after functional endoscopic sinus surgery (FESS) is a dilemma. Vitamin D3 (VD3) is known to inhibit the proliferation of nasal polyp-derived fibroblasts. The present study aimed to investigate the effects of oral VD3 on the recurrence of polyposis after FESS. MATERIALS AND METHODS: This triple-blind placebo-controlled clinical trial was conducted on 40 patients with CRSwNP who did not respond to medical treatment and were candidates for FESS. In addition, the patients had VD3 insufficiency. Following the surgery, all the patients received routine treatment (i.e., fluticasone spray, irrigation, cefixime 400 mg daily for 10 days, and montelukast for a month). Moreover, the case group received oral VD3 tablets 4000 IU (single daily dose) for a month, and the control group received placebo in the same manner. The Sino-Nasal Outcome Test (SNOT-22) and Meltzer endoscopic grading scores were recorded at months 1, 3, and 6 after the study. RESULTS: In this study, 6 months following the intervention, the severity of polyposis was reported to be significantly lower in the VD3 group compared to the placebo group based on SNOT-22 (16.25±10.16 in the VD3 group vs. 47.45±13.55 in the placebo group; P<0.001) and Meltzer scores (0.50±0.60 in the VD3 group vs. 2.65±0.93 in the placebo group; P<0.001). No adverse effects were observed in the case group. CONCLUSION: This study showed the efficacy and safety of vitamin D supplementation in the reduction of polyposis recurrence after FESS in patients with CRSwNP.

Correlation Between Lipid Profile and Acne Vulgaris.

BACKGROUND AND AIM: Acne is a common skin disease resulting from a complex interaction of various pathogenetic factors. The aim of this study was to find out lipid profile abnormalities in acne vulgaris patients. MATERIAL AND METHODS: This descriptive analytic cross-sectional study was conducted on 45 acne patients and 45 age- and sex-matched healthy controls to assess plasma total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and triglyceride (TG) levels. RESULTS: We showed a higher cholesterol level in acne patients (P=0.025), particularly in men (P=0.04). Other plasma lipids including TG, LDL, and HDL in male and female patients were higher compared to controls, but this is not statistically significant. DISCUSSION AND CONCLUSION: In conclusion, lipid profile was altered in our patients, with high cholesterol level as the commonest derangement, particularly in men. Therefore, screening for lipid profile abnormalities could be considered in the treatment of acne patients.

Value of Ultrasonography in Detection of Diaphragmatic Injuries Following Thoracoabdominal Penetrating Trauma; a Diagnostic Accuracy Study.

INTRODUCTION: Diagnosis of diaphragmatic rupture following thoracoabdominal penetrating trauma is very challenging in asymptomatic patients with stable vital signs. This study aimed to evaluate the diagnostic accuracy of focused assessment with sonography for trauma (FAST) in this regard. METHODS: This cross-sectional study was performed on patients referring to emergency department due to left thoracoabdominal stab wound during 2 years. All patients initially underwent ultrasonography and the screening performance characteristics of FAST in detection of diaphragmatic injuries were calculated, considering the findings of diagnostic laparoscopy as the gold standard test. RESULTS: Twenty-four patients with the mean age of 33 ± 10.64 years (16-61 years) were studied (100% male). The mean chest wall laceration size was 2.7 ± 2.7 cm (1-10 cm) and the most frequent location of wounds was posterior chest wall (42%) and in the 6th and 7th intercostal space (50%). Diaphragmatic rupture was seen in 4 (16.7%) patients based on diagnostic laparoscopy. Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratio of FAST in detection of diaphragmatic raptures were 50% (95% CI: 9.18 - 90.8), 100% (95% CI: 79.9 - 100.0), 100% (95% CI: 19.8 - 100.0), 9.1% (95% CI: 1.5 - 30.6), Infinity, and 0.1 (95% CI: 0.02 - 0.37), respectively. The overall accuracy of FAST in this regard was 75.0% (95% CI: 42.3 - 100.0). CONCLUSION: In patients with penetrating trauma to the left thoracoabdominal region, FAST cannot be the definitive alternative to diagnostic laparoscopy to detect diaphragm rupture.

Effect of local desmopressin administration on intraoperative blood loss and quality of the surgical field during functional endoscopic sinus surgery in patients with chronic rhinosinusitis: a triple-blinded clinical trial.

BACKGROUND: Bleeding during functional endoscopic sinus surgery always been a challenge for the quality of surgical field for surgeons. This study aimed to evaluate the effect of local nasal desmopressin premedication on blood loss and the quality of surgical field in functional endoscopic sinus surgery. METHODS: This study was conducted on 90 patients with chronic rhinosinusitis who were candidate for endoscopic sinus surgery. They were randomly assigned to two study groups. One group received a single puff of local desmopressin (10 µg) in each side of nasal cavity 30 min before the surgery and the other received normal saline instead. Blood loss and the quality surgical field were determined in 15, 30, 60 and 90 min during the surgery (scoring by BOEZAART grading system). All data were analyzed. RESULTS: Blood loss was significantly lesser in the desmopressin group (mean ± SD, 16.289 ± 5.605 ml) than in the control group (24.289 ± 5.2722 ml, P < 0.001).Surgeons were more satisfied with the surgical field in the desmopressin group than control group in all cutoff points (15, 30, 60, and 90 min during the surgery, P < 0.001). No side effects were observed using local desmopressin. CONCLUSIONS: Premedication with local desmopressin can reduce bleeding effectively and clear the surgical field during functional endoscopic sinus surgery.

A new right groin incision versus McBurney's incision for open appendectomy: a randomized controlled trial.

PURPOSE: We aimed to introduce a new surgical method for open appendectomy including a right groin incision with adipocutaneous flap and to compare its feasibility, safety, and cosmetic outcomes with classic McBurney's incision. METHODS: Patients with the diagnosis of acute appendicitis who were candidates for appendectomy surgery at General Surgery Department, Besat Hospital, Hamadan University of Medical Sciences, Iran, in 2016 and 2017, were enrolled in a randomized controlled clinical study. Patients were randomly assigned to two groups each containing 50 patients. In the case and control groups, patients underwent appendectomy using right groin incision with adipocutaneous flap and traditional McBurney's methods, respectively. RESULTS: One hundred patients with the mean age of 23.6 years (range = 4-44) old including 65 males were enrolled in the study. Patients' demographics, histopathology, and anatomical location of the appendix were not significantly different in the case and control groups. There was no significant difference in postoperative wound infection, cellulitis, hematoma, and seroma between the two groups. Patients in the case group were significantly more satisfied in terms of cosmesis than in the control group (P < .001); however, the operative time and pain were higher in the case group compared to the control group (P values = 0.016 and 0.033, respectively). CONCLUSIONS: The right groin incision for open appendectomy may be safe and feasible and the most cosmetically appealing method especially in children and patients with cosmetic concerns.

In patients suffering from idiopathic central serous chorioretinopathy, anxiety scores are higher than in healthy controls, but do not vary according to sex or repeated central serous chorioretinopathy.

INTRODUCTION: Idiopathic central serous chorioretinopathy (CSCR) is a relatively common ophthalmic disorder characterized by the development of a serous detachment of the sensory retina. Psychophysiological factors may trigger or maintain CSCR, though, surprisingly, the association between CSCR and anxiety has yet to be studied. The aims of the present study were threefold: to determine whether 1) Iranian patients with CSCR have higher scores for anxiety, 2) anxiety is lower, if CSCR has been experienced twice, and whether 3) anxiety scores differ between sexes. METHODS: A total of 30 patients with CSCR and 30 healthy age-and sex-matched controls took part in the study. A brief face-to-face interview was conducted covering demographic variables and history and occurrence of CSCR and assessing anxiety. RESULTS: Compared to healthy controls, anxiety was significantly higher in both first-time and second-time CSCR patients. In CSCR patients, anxiety scores did not differ between sexes. CONCLUSION: Higher anxiety scores were observed in Iranian patients with CSCR, irrespective of whether this was the first or second occurrence of CSCR. This suggests there is no psychological adaptation in terms of reduced anxiety among patients with repeated CSCR.

High Seroprevalence of Bordetella pertussis in Patients with Chronic Obstructive Pulmonary Disease: A Case-Control Study.

BACKGROUND: Bordetella pertussis has been suggested to take part in the acute exacerbation of chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate the association between B. pertussis and COPD. MATERIALS AND METHODS: In this case-control study, 90 patients with COPD and 90 age- and sex- matched control subjects were included. Serum samples were tested for anti-B. pertussis IgG and IgA by ELISA. A physician completed a questionnaire including demographic characteristics, habitual history and spirometric findings for each patient. RESULTS: Of 90 patients with chronic obstructive pulmonary disease, 66 (51%) had mild, 31 (34.4%) had moderate, and 13 (14.4%) had severe disease. There was no significant association between B. pertussis IgA seropositivity and COPD. Serum levels of anti- B. pertussis IgG were significantly higher in patients with COPD than in the control subjects (P < 0.001). No association was observed between B. pertussis infection and severity of COPD. CONCLUSION: The results suggest that there is an association between B. pertussis infection and COPD. Further studies should be planned to investigate the potential pathogenic mechanisms underlying these associations.

Frequency of alcohol and substance abuse observed in drivers killed in traffic accidents in Hamadan, Iran.

Human factor is one of the most important causes for traffic accidents. This study has been designed to determine the presence of alcohol and drug abuse among drivers killed in car accidents in Hamadan, Iran during a one year period. This study was conducted as a post-mortem series design. Forensic autopsies were performed on all drivers killed in car accidents who were referred to the Hamadan Medico-legal Center. Alcohol and drug abuse was evaluated in these drivers. Of the 106 drivers killed in car accidents, 98.1% were male. Most were 20-30 years of age. In the majority of cases (83%) the toxicologic tests were negative. Higher level of education (diploma and higher) was related to higher alcohol or drug abuse compared with those whose educational status was less than a diploma (46.7%) or those who were illiterate (16.5%; Chi-square: 7.13; P = 0.008). There was a remarkable difference between drug or alcohol abuse and season. The majority of substance abusers were in the summer (n = 13, 59.1%); the least were in the spring (n = 2; 9.1%). This study shows that alcohol and drug abuse, in particular opiates, could be important factors in traffic accidents in Hamadan, Iran.

Relationship between Helicobacter pylori infection and chronic obstructive pulmonary disease.

There is some evidence indicating the role of Helicobacter pylori infection in pathogenesis of extragastrointestinal diseases including skin, vascular, and autoimmune disorders, as well as some respiratory diseases. The aim of this study was to investigate the association between H. pylori and chronic obstructive pulmonary disease (COPD). In a case-control study, 90 patients with COPD and 90 age- and sex- matched control subjects were included. Serum samples were tested for anti-H. pylori and anti-CagA IgG by ELISA. A physician completed a questionnaire including demographic characteristics, habitual history, and spirometric findings for each patient. Of 90 patients with COPD 66 (51%) had mild, 31 (34.4%) moderate, and 13 (14.4%) sever disease. There was no significant association between H. pylori IgG seropositivity and COPD. Serum levels of anti-CagA IgG were significantly higher in patients with COPD than in the control subjects (P < 0.001). No association was observed between H. pylori infection and severity of COPD. The results suggest that there is an association between CagA-positive H. pylori infections and COPD. Further studies should be planned to investigate the potential pathogenic mechanisms that might underlie these associations.

Bacterial aetiology and antimicrobial resistance of community-acquired pneumonia in the elderly and younger adults.

This study was undertaken in order to compare the frequency of bacterial agents of community-acquired pneumonia (CAP) and their antimicrobial resistance in the elderly and younger adults admitted to a teaching hospital in Hamedan, Iran. A total of 150 cases of CAP, including 81 elderly and 69 younger adults, were evaluated. The most frequently identified pathogens in younger adults were Moraxella catarralis (11.5%), Streptococcus pneumonia (10.1%) and Staphylococcus aureus (10.1%); while in the elderly the most frequent were S. pneumonia (12.3%), S. aureus (6.1%) and Pseudomonas aeruginosa (6.1%). No significant differences were observed between the frequency and antimicrobial resistance pattern of isolated pathogens in either age group. We concluded that the cause of CAP in the elderly follows the general trend of infection in the younger population. Increased resistance of isolated bacteria to the current antibiotics highlights the need for further investigation of newer antibiotics for the treatment of CAP.

Seroprevalence of Immunoglobulin G antibodies against pertussis toxin among asymptomatic medical students in the west of Iran: a cross sectional study.

BACKGROUND: Pertussis is a highly communicable, vaccine-preventable respiratory infection. Immune response against this disease can be induced by infection or vaccination. Protection after childhood vaccination is minimal after ten years. Our aim was to assess pertussis immunity state in a population of healthy young medical students. METHODS: In this seroepidemiological survey, blood samples were obtained from 163 first-year medical students in Hamedan University, Iran. Serum level of IgG against pertussis toxin (IgG-PT) was measured by Enzyme-Linked Immunosorbent Assay (ELISA) method. For qualitative assessment, IgG-PT levels more than 24 unit (U)/ml were considered positive. Data was analysed qualitatively and quantitatively considering gender and age groups. RESULTS: There were 83 males and 80 females, with a mean age of 19.48 years, Prevalence of IgG-PT was 47.6% with mean level of 71.7 u/ml (95% confidence interval: 68.1-75.3). No statistically significant difference was observed with respect to sero-positivity of IgG-PT between males and females (45 cases (54%) vs. 34 cases (42%); P = 0.06). Mean IgG-PT levels in males and females were 84 U/ml and 58.8 U/ml, respectively (P = 0.91). CONCLUSION: A considerable proportion of our study population with a positive history of childhood vaccination for pertussis was not serologically immune to pertussis. A booster dose of acellular pertussis vaccine may be indicated in Iranian, medical students regarding their serologic conditions and outstanding role in health care systems.
