RESUMO

BACKGROUND: Smoking is the major risk factor for tracheal, bronchus, and lung (TBL) cancers. We investigated the feasibility of projecting TBL cancer incidence using smoking incidence rates by incorporating a range of latent periods from the main risk factor exposure to TBL cancer diagnosis. METHODS: In this ecological study, we extracted data on TBL cancer incidence rates in Iran from 1990 to 2018 from the Global Burden of Disease (GBD) database. We also collected data on Iranian cigarette smoking patterns over the past 40 years through a literature review. The weighted average smoking incidence was calculated using a fixed-effects model with Comprehensive Meta-Analysis (CMA) software. Using these data, the five-year TBL cancer incidence in Iran was projected through time series modeling with IT Service Management (ITSM) 2000 software. A second model was developed based on cigarette smoking incidence using linear regression with SPSS (version 22), incorporating different latent periods. The results of these two models were compared to determine the best latent periods. RESULTS: An increasing trend in TBL cancer incidence was observed from 2019 to 2023 (first model: 10.30 [95% CI: 9.62, 10.99] to 11.42 [95% CI: 10.85, 11.99] per 100,000 people). In the second model, the most accurate prediction was obtained with latent periods of 17 to 20 years, with the best prediction using a 17-year latent period (10.13 to 11.40 per 100,000 people) and the smallest mean difference of 0.08 (0.84%) per 100,000 people using the standard forecasting model (the ARIMA model). CONCLUSION: Projecting an increase in TBL cancer incidence rates in the future, an optimal latent period of 17 to 20 years between exposure to cigarette smoke and TBL cancer incidence has implications for macrolevel preventive health policymaking to help reduce the burden of TBL cancer in upcoming years.

RESUMO

BACKGROUND: Type 2 diabetes mellitus (T2DM) requires a continues bulk of cares. It is very probable COVID-19 pandemic is affected its healthcare coverage. METHODS: The interrupted time series analysis is used to model the trend of diabetes healthcare indices, such as the health worker visits, physician visits, body mass index (MBI), fasting blood sugar (FBS), and hemoglobin A1c (HbA1c), before and after the start of COVID-19 pandemic. The reference of data was the totals of all T2DM patients living in Fars Province, Southern Iran, areas covered by Shiraz University of Medical Science (SUMS), from 2019 to 2020. RESULTS: A significant decrease for visits by the health workers, and physicians was observed by starting COVID-19 pandemic (ß2 = -0.808, P < 0.001, ß2 = -0.560, P < 0.001); Nevertheless, the coverage of these services statistically increased by next months (ß3 = 0.112, P < 0.001, ß3 = 0.053, P < 0.001). A same pattern was observed for the number of BMI, FBS and HbA1c assessments, and number of refer to hospital emergency wards (ß3 = 0.105, P < 0.001; ß3 = 0.076, P < 0.001; ß3 = 0.022, P < 0.001; ß3 = 0.106, P < 0.001). The proportion of T2DM patients with HbA1C < 7%, and controlled hypertension during study period was statistically unchanged. CONCLUSIONS: When the COVID-19 pandemic was announced, T2DM healthcare coverage drastically decreased, but it quickly began to rebound. The health monitoring system could not have any noticeable effects on diabetes outcomes.

RESUMO

OBJECTIVES: This study aimed to compare pregnant and non-pregnant women infected with SARS-CoV-2 disease (COVID-19) in terms of in-hospital mortality. METHODS: This historical cohort study was conducted on hospitalized women of reproductive ages (15-49 years) infected with SARS-CoV-2 in Fars province, Iran during 15 March 2019-10 May 2021. RESULTS: Out of the 5,322 patients, 330 were pregnant. The fatality rate of SARS-CoV-2 was 1.2% amongst pregnant women and 3.5% amongst non-pregnant ones. Pregnant and non-pregnant women reported the same history of smoking, opium use, previous COVID-19 infection, vaccination against SARS-CoV-2, and COVID-19 symptoms (p>0.05 for all). However, the pregnant women were younger and had fewer underlying diseases (p<0.001 for both). The results revealed no significant difference between the two groups regarding in-hospital clinical manifestations including the number of days after the onset of COVID-19 symptoms, mechanical ventilation, and long involvement (cRR; 95% CI=0.99 (0.96-1.02), 1.18 (0.72-2.02), and 0.95 (0.88-1.02), respectively). Nonetheless, Intensive Care Unit (ICU) admission was significantly higher in pregnant women (cRR; 95% CI=2.37(1.85-3.02)). After adjusting for age, history of underlying diseases, and ICU admission, pregnant women showed lower in-hospital mortality due to COVID-19 compared to non-pregnant women (aRR; 95% CI=0.32 (0.12-0.87)). CONCLUSIONS: Based on the current study findings, pregnant women showed lower in-hospital mortality due to COVID-19 compared to non-pregnant ones. Nevertheless, they should follow the same recommendations as non-pregnant women, avoiding exposure to the virus and receiving medical treatment and vaccination. Further studies are recommended to address the follow-up of recovered pregnant women, their babies, and puerperium.

RESUMO

Background: Concerns about the side effects of SARS-CoV-2 vaccines have been raised nationwide. We aimed to compare the time to report the side effects of the Oxford-AstraZeneca and Sinopharm COVID-19 vaccines. Methods: Information on side effects of AstraZeneca and Sinopharm COVID-19 vaccines was obtained from the COVID-19 Symptom Study App affiliated with Shiraz University of Medical Science during 2021. A COX regression model with an adjusted Hazard Ratio and 95% Confidence Interval; HR (95% C.I) was reported at the significance level of < 0.05. Results: 4478 and 5555 participants received the AstraZeneca and Sinopharm vaccines, respectively; more age, history of SARS-CoV-2 infection, first vaccine dose, hypertension, and hypertension with cardiovascular disease were seen in the AstraZeneca group (P < 0.05 for all). However, the AstraZeneca group had lower immune deficiency and time to report the side effects (P < 0.05 for both). There was significantly less time to pain HR(95% C.I.); 0.50 (0.47-0.52), vertigo 0.65 (0.61-0.69), weakness 0.41 (0.38-0.44), headache 0.43 (0.39-0.74), anorexia 0.31 (0.28-0.34), nausea 0.56 (0.51-0.62), severer allergy 0.71 (0.63-0.81), general inflammation 0.27 (0.23-0.31), fever > 38oC 0.12 (0.1-0.15), eye inflammation 0.45 (0.39-0.52), diarrhea 0.85 (0.73-0.99), blurred vision 0.73 (0.61-0.86), injection site redness 0.32 (0.26-0.39), fatigue/paleness 0.53 (0.50-0.57), joint pain 0.55 (0.41-0.73), auxiliary gland inflation 0.59 (0.43-0.80), convulsions 0.30 (0.17-0.52), and severe side effects 0.3 (0.27-0.33) in the AstraZeneca group; However, skin rash 0.77 (0.57-1.05) and hospitalization 0.72 (0.21-2.55) were the same. Conclusion: Sinopharm COVID-19 vaccine recipients reported longer times to report vaccine-related side effects than AstraZeneca; due to the lack of adverse effects like hospitalization, vaccination should continue to control the pandemic; more real-population studies are needed on the long-term effects of vaccination against COVID-19.

RESUMO

BACKGROUND AND OBJECTIVE: Ivermectin is a known anti-parasitic agent that has been investigated as an antiviral agent against coronavirus disease 2019 (COVID-19). This study aimed to evaluate the efficacy of ivermectin in mild COVID-19 patients. METHODS: In this multi-arm randomized clinical trial conducted between 9 April 2021 and 20 May 2021, a total of 393 patients with reverse transcription-PCR-confirmed COVID-19 infection and mild symptoms were enrolled. Subjects were randomized in a 1:1:1 ratio to receive single-dose ivermectin (12 mg), double-dose ivermectin (24 mg) or placebo. The primary outcome was need for hospitalization. RESULTS: There was no significant difference in the proportion of subjects who required hospitalization between the placebo and single-dose ivermectin groups (absolute difference in the proportions: -2.3 [95% CI = -8.5, 4.1]) and between the placebo and double-dose ivermectin groups (absolute difference in the proportions: -3.9 [95% CI = -9.8, 2.2]). The odds of differences in mean change in severity score between single-dose ivermectin and placebo groups (ORdifference  = 1.005 [95% CI: 0.972, 1.040]; p = 0.762) and double-dose ivermectin and placebo groups (ORdifference  = 1.010 [95% CI: 0.974, 1.046]; p = 0.598) were not statistically significant. None of the six adverse events (including mild dermatitis, tachycardia and hypertension) were serious and required extra action. CONCLUSION: Single-dose and double-dose ivermectin early treatment were not superior to the placebo in preventing progression to hospitalization and improving clinical course in mild COVID-19.

RESUMO

BACKGROUND: Health costs have increased significantly around the world, and cost assessments have become important. This study aimed to collect cost of the resources used in the national hepatitis B immunization program in Southern Iran. METHODS: Costs were calculated by investigating the available documents as well as consulting with knowledgeable personnel. These costs were collected using the data from Shiraz University of Medical Sciences. According to the health payer's perspective, the indirect costs of the people were not taken into account. All current and capital costs in year 2017 were calculated and converted to US dollars (USDs). RESULTS: In 2017, 33 204 children received hepatitis B vaccine. The total cost of the national hepatitis B vaccination program in Shiraz and the cost of vaccination per child were 473 506 and 14.26 USD, respectively. However, the cost of inoculation of hepatitis B vaccine per dose was estimated at 3.20 USD. Personnel costs constituted the highest proportion (53.84%) of total costs. CONCLUSIONS: The cost of hepatitis B vaccination in Iran was lower than other countries. Considering that personnel costs had the largest proportion, it is recommended that proper measures be taken to monitor and modify these costs if necessary.

RESUMO

BACKGROUND: Given that COVID-19 continues to spread worldwide, attempts to restrain the virus and to prevent the effects that critically ill patients with COVID-19 have on healthcare systems, has become a public health priority. This ecological study aimed to investigate the correlation between the Human Development Index (HDI) and the epidemiological indicators of COVID-19, including the cumulative incidence rate of cases, the cumulative incidence rate of death, performed COVID-19 tests per million, recovery rate, and case fatality rate. METHODS: In this ecological study, a data set was provided, which included the epidemiologic indices of COVID-19, HDI, and its components for each country. Correlation coefficients were used to determine linear correlation. Also, the scatter plots of the HDI for the studied countries based on the epidemiologic indices of COVID-19 were drawn. RESULTS: This study showed that HDI and its components had positive correlation with a cumulative incidence rate of cases, the cumulative incidence rate of death, and performed COVID-19 tests (p < 0.001). HDI and two of its components, including literacy and Gross National Income (GNI) components had negative correlation with case fatality rate (CFR). Also, HDI and two of its components, including literacy and life expectancy components had negative correlation with recovery rate. CONCLUSION: Our study showed that the HDI and its components can affect the epidemiological status of COVID-19. As HDI increased, the cumulative incidence rate of cases, cumulative incidence rate of death, and COVID-19 tests increased as well. As HDI increased, CFR and recovery rate decreased as well. Although the HDI is higher in high-income countries, these countries may have also better reporting and surveillance systems.

RESUMO

Background: Using time series and spatiotemporal analyses, this study aimed to establish an Early Warning System (EWS) for COVID-19 in Fars province Iran. Methods: A EWS was conducted on (i) daily basis city-level time series data including 53 554 cases recorded during 18 February-30 September 2020, which were applied to forecast COVID-19 cases during 1 October-14 November 2020, and (ii) the spatiotemporal analysis, which was conducted on the forecasted cases to predict spatiotemporal outbreaks of COVID-19. Results: A total of 55 369 cases were forecasted during 1 October-14 November 2020, most of which (26.9%) occurred in Shiraz. In addition, 65.80% and 34.20% of the cases occurred in October and November, respectively. Four significant spatiotemporal outbreaks were predicted, with the Most Likely Cluster (MLC) occurring in ten cities during 2-22 October (P < 0.001 for all). Moreover, subgroup analysis demonstrated that Zarrindasht was the canon of the epidemic on 6 October (P=0.04). As a part of EWS, the epidemic was triggered from Jahrom, involving the MLC districts in the center, west, and south parts of the province. Then, it showed a tendency to move towards Zarrindasht in the south and progress to Lar in the southernmost part. Afterwards, it simultaneously progressed to Fasa and Sepidan in the central and northwestern parts of the province, respectively. Conclusion: EWS, which was established based on the current protocol, alarmed policymakers and health managers on the progression of the epidemic and on where and when to implement medical facilities. These findings can be used to tailor province-level policies to servile the ongoing epidemic in the area; however, governmental level effort is needed to control the epidemic at a larger scale in the future.

RESUMO

PURPOSE: Among oral conditions, tooth decay is the most common chronic childhood disease. Children's dental caries are influenced by several factors, among which diet is one of the most highlighted ones. The present study was conducted to examine the decayed, missing and filled teeth in primary dentition (dmft) and caries-free (CF) indexes as well as the impact of nutrition and demographic factors on oral health of 2- to 6-year-old children in Fars Province. METHODS: A cross-sectional study was conducted on children aged 2-6 years old to evaluate dmft and CF indices according to the latest WHO standards as well as their demographic characteristics in 2018. A questionnaire was used for data collection. RESULTS: A total of 2220 children were recruited. The mean dmft was 1.37 ± 2.69. The components of the dmft score included decay (1.23 ± 2.6), missing (0.03 ± 0.11) and filling (0.11 ± 0.7) in primary dentition, and the prevalence of caries-free children was 66.5%. The results showed that dmft had a significant positive relationship with breastfeeding termination time, maternal education level and maternal age. Birth weight, consumption of iron, vitamin A and D supplements, age at onset of complementary feeding and maternal occupation had no significant relationship with dmft. CONCLUSIONS: The tooth decay index of 2- to 6-year-old children in Fars Province is very different from WHO global standards. Therefore, educating mothers about the duration of breastfeeding is important to achieve standard values for the dental caries index.

RESUMO

BACKGROUND: Although almost a year has passed since the Coronavirus disease 2019 (COVID-19) outbreak and promising reports of vaccines have been presented, we still have a long way until these measures are available for all. Furthermore, the most appropriate corticosteroid and dose in the treatment of COVID-19 have remained uncertain. We conducted a study to assess the effectiveness of methylprednisolone treatment versus dexamethasone for hospitalized COVID-19 patients. METHODS: In this prospective triple-blinded randomized controlled trial, we enrolled 86 hospitalized COVID-19 patients from August to November 2020, in Shiraz, Iran. The patients were randomly allocated into two groups to receive either methylprednisolone (2 mg/kg/day; intervention group) or dexamethasone (6 mg/day; control group). Data were assessed based on a 9-point WHO ordinal scale extending from uninfected (point 0) to death (point 8). RESULTS: There were no significant differences between the groups on admission. However, the intervention group demonstrated significantly better clinical status compared to the control group at day 5 (4.02 vs. 5.21, p = 0.002) and day 10 (2.90 vs. 4.71, p = 0.001) of admission. There was also a significant difference in the overall mean score between the intervention group and the control group, (3.909 vs. 4.873 respectively, p = 0.004). The mean length of hospital stay was 7.43 ± 3.64 and 10.52 ± 5.47 days in the intervention and control groups, respectively (p = 0.015). The need for a ventilator was significantly lower in the intervention group than in the control group (18.2% vs 38.1% p = 0.040). CONCLUSION: In hospitalized hypoxic COVID-19 patients, methylprednisolone demonstrated better results compared to dexamethasone. TRIAL REGISTRATION: The trial was registered with IRCT.IR (08/04/2020-No. IRCT20200204046369N1 ).

RESUMO

BACKGROUNDS: Cardiovascular Diseases (CVDs) are the first leading cause of death worldwide. The present study aimed to investigate the relationship between demographics, anthropometrics, sleep duration, physical activity, and ECG parameters in the Fasa Persian cohort study. METHODS: In this cross-sectional study, the basic information of 10,000 participants aged 35-70 years in the Fasa cohort study was used. The data used in this study included demographic data, main Electrocardiogram (ECG) parameters, anthropometric data, sleep duration, and physical activity. Data analysis was performed using t-test, chi-square, and linear regression model. RESULTS: Based on multivariate linear regression analysis results, increased age was significantly associated with all study parameters. Nevertheless, gender and body mass index showed no significant relationship with SV3 and PR. Wrist circumference, hip circumference and waist circumference significantly increased the mean values of the ECG parameters. However, sleep duration was not significantly associated with the ECG parameters. In addition, hypertension was major comorbidity, which was shown to increase the mean values of the ECG parameters. CONCLUSION: Several factors affected the ECG parameters. Thus, to interpret ECGs, in addition to age and gender, anthropometric indices, physical activity, and previous history of comorbidities, such as hypertension and ischemic heart disease, should be taken into consideration.

RESUMO

BACKGROUND: School closure is one of the main policies of global health care strategies performed worldwide. Despite all benefits, there might be some threats for younger groups spending their time in quarantine. This study aims to determine the impacts of lockdown and school closure on children's major lifestyle aspects, especially their leisure and sleep pattern during the COVID-19 pandemic. METHODS: For the purpose of this study, an online questionnaire was distributed from 14th to 31st of March 2020 among the schools and students from the first grade to the 12th grade (before university) in Fars province, southern Iran. The questionnaire consisted of five sections which included data regarding the students' general information, activity priorities, adherence to quarantine, attitude toward school closure, and sleep patterns. RESULTS: In our study, 20,697 filled questionnaires were received from the participants with an average age of 13.76 years; 29.7% of them were male, 80.6% were from urban areas, and 83.3% were from public schools. The overall first preference of students during school closure was mobile and computer games (30.1%), followed by studying (26.6%) and watching television (13.8%). Our results demonstrated that the majority of students adhered to social distancing and there was also a significant correlation among education levels and desire for schools to be closed till the end of the semester (P = 0.015). Also, regarding sleep patterns, the majority (53.5%) had above 12 h of sleep throughout the day. CONCLUSION: It seems that lockdown following COVID-19 pandemic has changed various aspects of the students' lifestyle remarkably, especially by increasing screen time and even sleep duration and pattern. We believe that certain strategies should be implemented by the Health and Educational Ministry to control not only the visible side effects of the quarantine period, but also the collateral consequences on their psychological and mental health.

RESUMO

Background: One of the main health problems in the world is hepatitis B virus (HBV) infection. Vaccination and other factors can affect HBV infection. As various effective factors have been reported in different regions and studies, this study aimed to investigate the association between HBV infection and routine vaccination and other effective factors 25 years since the launch of the national vaccination program in Iran. Methods: This cross-sectional study, conducted in 2017 in Shiraz (Iran), investigated factors such as demographic variables such as gender, education, and occupation, vaccination status, and the potential risk factors for HBV infection. Hepatitis B surface antigen (HBsAg) and anti-hepatitis B core antibody (HBc Ab) tests were performed to determine HBV infection status. The data were analyzed using R software (version 3.5.2), using multivariate logistic regressions and machine learning methods. The level of significance was considered below 0.05. Results: A total of 2720 individuals were enrolled in the study (194 cases with HBV infection). Based on the logistic regression analyses, factors such as a family history of the disease (OR=2.53, P<0.001), vaccination (OR=0.57, P=0.004), a history of high-risk behaviors (OR=1.48, P=0.022), and occupation (OR=1.80, P=0.035) were significantly associated with HBV infection. Based on the conditional tree method, a family history of infection (P<0.001) and vaccination (P=0.023) were two important factors in classifying individuals for HBV infection. Conclusion: Based on the different methods applied in this study, HBV infection was affected by factors such as a family history of the disease, national HBV vaccination, and occupation. It appears that HBV vaccination, launched by the Iranian Ministry of Health and Medical Education in 1993, has reduced HBV infection.

RESUMO

PURPOSE: COVID-19 is a novel, severely contagious and progressive infection occurring worldwide. The diagnosis of the disease is based on real-time polymerase chain reaction (RT-PCR) and computed tomography (CT) scan, even though they are still controversial methods. MATERIAL AND METHODS: We studied 54 patients with suspected COVID-19 and the two mentioned methods were compared with each other. RESULTS: Sensitivity and specificity of the abnormal chest CT scan, ground-glass opacity (GGO), consolidation opacity, and both of GGO and consolidation were also surveyed based on RT-PCR. The results showed that RT-PCR assay was negative in 23 (42.6%) patients and positive in 31 (57.4%) cases. Also, the patients with an abnormal chest CT scan comprised 37 (68.5%). The sensitivity and specificity of abnormal CT scan were 78.6% and 42.3%, respectively, based on the RT-PCR method. CONCLUSIONS: Other techniques alongside CT scan and RT-PCR are advocated for accuracy of the COVID-19 diagnosis.

RESUMO

Viruses are incomplete elements that require other organisms to survive and multiply, hence constantly mutate during its evolution, resulting from adaptations in response to environmental changes such as the immune response of the host. In this line, they are responsible for many diseases, but today, there is evidence that viruses have many benefits and even have a unique ecosystem to control the different species or strain of themselves. While highlighting the benefits of some viruses and the undesirable effects of their eradication, the present review expresses the idea of the viral ecosystem and its importance, which has been supported in several studies. There are countless articles about virus-related illnesses and the undesirable effects of therapeutic interventions in eliminating the less pathogenic viruses or manipulating viral ecosystems. By simulating the viral ecosystem with an ecosystem found among the snakes, it can be assumed that the viruses have concentric zones, which its inner zone includes the most dangerous viruses for humans and each zone is surrounded and controlled by an outer zone of less dangerous viruses for humans. The outermost zone consists of viruses that are least dangerous to humans such as common cold that protect humans and possibly other living organisms against more dangerous viruses in inner zone, causing the activation of immune system by playing a unique and pivotal role in the ecosystems. Therefore, manipulating the ecosystem and disrupting the balance might have epidemics and harmful consequences for the plants, animals, and human.

RESUMO

BACKGROUND: In March 2020, the WHO declared the novel coronavirus (COVID-19) outbreak a global pandemic. Although the number of infected cases is increasing, information about its clinical characteristics in the Middle East, especially in Iran, a country which is considered to be one of the most important focal points of the disease in the world, is lacking. To date, there is no available literature on the clinical data on COVID-19 patients in Iran. METHODS: In this multicenter retrospective study, 113 hospitalized confirmed cases of COVID-19 admitted to university affiliated hospitals in Shiraz, Iran from February 20 to March 20 were entered in the study. RESULTS: The mean age was 53.75 years and 71 (62.8%) were males. The most common symptoms at onset were fatigue (75: 66.4%), cough (73: 64.6%), and fever (67: 59.3%). Laboratory data revealed significant correlation between lymphocyte count (P value = 0.003), partial thromboplastin time (P value = 0.000), international normalized ratio (P value = 0.000) with the severity of the disease. The most common abnormality in chest CT scans was ground-glass opacity (77: 93.9%), followed by consolidation (48: 58.5%). Our results revealed an overall 8% (9 out of 113 cases) mortality rate among patients, in which the majority was among patients admitted to the ICU (5: 55.6%). CONCLUSION: Evaluating the clinical data of COVID-19 patients and finding the source of infection and studying the behavior of the disease is crucial for understanding the pandemic.

RESUMO

BACKGROUND: Suicide is a critical psychological issue worldwide with an increasing trend. This study investigated suicide comprehensively. METHODS: In this cross-sectional study, we reviewed data of 28 552 suicide attempts during 2011-16, in Southern Iran. To calculate age-standardized incidence rates, population statistics were derived from the Statistical Center of Iran and the National Organization for Civil Registration. We used the standard population of World Health Organization 2012 to adjust the suicide attempts and deaths rates by age. RESULTS: The mean age of participants was 26.8 ± 10.6 years with the highest suicide attempts rates in the age groups of 15-24 and 25-34 years (48% and 32.5%, respectively); 58.7% were women and 52.9% were single. Case-fatality rate (CFR) was 6.27%. Annual age-standardized incidence rates of suicide attempts during the 6-year period has increased (P < 0.001), and that of deaths were not incremental (P > 0.05). Logistic regression model showed male sex, rural area, older age, psychological and somatic disorders, and family history of suicide as significant factors. CONCLUSIONS: In this comprehensive study, although the age-standardized mortality rate of suicide in southern Iran was lower than in other countries, the increasing trend of suicide attempts during the study period served as an alarming sign in this province.

RESUMO

OBJECTIVE: Multiple studies have shown worse outcomes in patients admitted for medical and surgical conditions on the weekend. However, past literature analyzing this "weekend effect" on subarachnoid hemorrhage (SAH) found no significant increase in mortality. This study utilizes more recent data to re-evaluate the association between weekend admission and mortality of patients hospitalized for SAH. METHODS: This retrospective cohort study queried the SAH patients in the Nationwide Inpatient Sample (NIS) database who were discharged from 2006 through 2014 during the weekend. RESULTS: Of the 54,703 admissions for SAH identified during the study period, 14,821 (27.1%) occurred over the weekend. Patients admitted over the weekend had a mean age of 59.2 years and were most likely to be female (59.6%), to be white (62.9%), located in the south region of the USA (40.1%), and be admitted to a teaching hospital (74.4%). When compared directly to weekday admissions, patients admitted over the weekend had higher odds of in-hospital mortality (odds ratio 1.07; confidence interval 95%, 1.02-1.12). There was no significant difference shown in the rate patients get surgical clipping versus endovascular coiling (p = 0.28) or the amount of time between admission to procedure for clipping (p = 0.473) or coiling (p = 0.255) on the weekend versus a weekday. CONCLUSION: Based on our findings, the likelihood of the in-hospital mortality was higher for patients admitted over the weekend. However, the characteristics of the study, primarily observational, prevent us arriving at an accurate conclusion about why this occurs; hence, we believe it is an important starting point to consider for future research.

RESUMO

BACKGROUND: Many patients with type 2 diabetes are uncontrolled on maximum oral treatment. The early introduction of insulin can lower diabetes-related complications. This study aimed to evaluate type 2 diabetes patients' demographic characteristics, clinical factors, and attitude toward insulin therapy initiation. METHODS: In the present cross-sectional study, 457 patients were selected from 12 diabetes clinics in the southern Iranian city of Shiraz in 2017. Adult patients (>30 y) with type 2 diabetes indicated to use insulin for the first time (insulin-naive) were asked to complete a researcher-designed questionnaire. The data were analyzed using SPSS 19. The relationships between insulin and the tendency to use insulin, demographic characteristics, and clinical data were evaluated using the χ2 or t test and logistic regression. The significance level was considered at 0.05. RESULTS: The mean age of the participants was 55.16±8.76 years and 67.4% were female. Despite physician recommendations, 60.2% of the patients were disinclined to use insulin. Those unwilling to initiate insulin therapy had more misconceptions. In the multivariate analysis, the chances of insulin noncompliance were increased by 4.63-fold among the patients without supplementary insurance (P<0.001), by 2.38-fold among those with a nondiabetic diet (P=0.002), and by 6.75-fold among the illiterate ones (P<0.001). CONCLUSION: Based on the results, the factors affecting insulin noncompliance in our insulin-naive patients with type 2 diabetes included insurance coverage, illiteracy, and nondiabetic regimens as well as misconceptions about and irrational fear of insulin injection. Overall, our results indicate the need for further education and financial support for patients and health staff.

RESUMO

OBJECTIVE: This study aimed to identify differences in perceptions between healthcare and non-healthcare personnel when it comes to wearing scrubs in non-healthcare settings. METHODS: An anonymous survey with 11 closed-ended questions sent via e-mail to healthcare students and employees at The University of Texas Health San Antonio and non-healthcare students and employees at The University of Texas at San Antonio. The answers were scored from 1 to 5 for each question, with a total score ranging from 11-55. Total scores were analyzed and compared between the two groups using a sample t test. RESULTS: 2730 people responded to the survey. The mean healthcare-related group responses scored 33.96 ± 7.65, while the non-healthcare group scored 34.47 ± 8.08, (p=0.096). CONCLUSIONS: In this study, we found no significant difference in attitudes about wearing scrubs in public between healthcare and non-healthcare; it appears that both groups are concerned about wearing scrubs in public. Both groups agree with the value of wearing scrubs in the clinical settings only. Healthcare professionals in this study did not endorse the need to change out of scrubs after work, while non-healthcare subjects believed changing one's scrubs before leaving a clinical setting was proper. The authors believe healthcare institutions should emphasize wearing scrubs only in professional circumstances, make a distinction between uniform and surgical scrubs, provide clean surgical scrubs to their employees, and designate locker rooms to encourage staff to change before the end of the work period.
