RESUMEN
BACKGROUND: This study measured the concentrations of arsenic (As), aluminum (Al), cadmium (Cd), chromium (Cr), mercury (Hg), nickel (Ni), and lead (Pb) in the urine samples of the Iranian adult population. METHODS: This nationally representative study was conducted on 490 participants in six provinces of Iran who were selected based on the clustering method. Participants included healthy Iranian adults aged above 25 years without a history of illness and non-smokers. Fasting urine sampling, body composition, and demographic measurements were performed for each participant. Urine samples were analyzed by acid digesting method using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The analysis included descriptive statistics and multiple linear regression using Python programming language. RESULTS: The geometrical mean (with corresponding reference values, µg/l) concentrations of metal(loid)s in urine for women, men, and both were 198.2 (625.3), 163.5 (486.1), and 192.5(570.4) for Al, 15.6(51.7), 28.8(71.1), and 21.9 (61.64) for As, 18.5(55.2), 20.7(56.5), and 19.22(55.75) for Pb, 17.9(57.6), 17.9 (53.9), and 17.9(56) for Ni, 13.95(47.5), 20.3(62.2) and 16(51.6) for Cr, 3.5(12.2), 2.9(11.5), and 3.3(12) for Hg, 0.74(2.7), 0.95 (3.6), and 0.81(3.1) for Cd. There was a direct relationship between the concentration of metal(loid)s and demographic indicators and body composition (P<0.05). Moreover, there was a direct relationship between the concentration of As, Cr, Hg, Ni, and Pb with age and wealth index (P<0.05). CONCLUSIONS: The concentrations found could be used as the reference range for As, Al, Cd, Cr, Hg, Ni, and Pb for human biomonitoring studies on the Iranian adult population.

Exposure to metal(loid)s can cause adverse health effects. This study evaluated the concentrations of aluminum, arsenic, cadmium, chromium, mercury, nickel, and lead in particulate matter <10 µm (PM10) and in the urine of 100 participants from urban residential areas in Iran. A total of 100 residential buildings (one adult from each household) in six cities across Iran were recruited for this study. The levels of metal(loid)s in PM10 and the urine of participants were measured using acid digestion followed by inductively coupled plasma mass spectrometry (ICP-MS). The average (±SE) PM10 concentration in the buildings was 51.7 ± 3.46 µg/m3. Aluminum and cadmium had the highest and lowest concentrations among the metal(loid)s, averaging 3.74 ± 1.26 µg/m3 and 0.01 ± 0.001 µg/m3, respectively. In 85 % of the samples, the concentration of metal(loid)s in indoor air exceeded WHO air quality standards. Cadmium and lead had the highest and lowest numbers of indoor air samples exceeding the recommended standards, respectively. A significant correlation was found between the concentration of metal(loid)s in urine samples and indoor PM10 levels, as well as the wealth index of participants. There was also a significant direct relationship between the concentrations of nickel, arsenic, lead, and mercury in urine and the age of participants. Factors such as building location, type of cooling systems, use of printers at home, and natural ventilation influenced the concentration and types of metal(loid)s in the indoor air.

Aims: To investigate the journey of patients with diabetes in the healthcare system using nationally-representative patient-reported data. Methods: Participants were recruited using a machine-learning-based sampling method based on healthcare structures and medical outcome data and were followed up for three months. We assessed the resource utilization, direct/indirect costs, and quality of healthcare services. Results: One hundred fifty-eight patients with diabetes participated. The most utilized services were medication purchases (276 times monthly) and outpatient visits (231 times monthly). During the previous year, 90% of respondents had a laboratory fasting blood glucose assessment; however, less than 70% reported a quarterly follow-up physician visit. Only 43% had been asked about any hypoglycemia episodes by their physician. Less than 45% of respondents had been trained for hypoglycemia self-management. The annual average health-related direct cost of a patient with diabetes was 769 USD. The average out-of-pocket share of direct costs was 601 USD (78.15%). Medication purchases, inpatient services, and outpatient services summed up 79.77% of direct costs with a mean of 613 USD. Conclusion: Healthcare services focused solely on glycemic control and the continuity of services for diabetes control was insufficient. Medication purchases, and inpatient and outpatient services imposed the most out-of-pocket costs.

BACKGROUND: Assessment of quality and cost of medical care has become a core health policy concern. We conducted a nationwide survey to assess these measures in Iran as a developing country. To present the protocol for the Iran Quality of Care in Medicine Program (IQCAMP) study, which estimates the quality, cost, and utilization of health services for seven diseases in Iran. METHODS: We selected eight provinces for this nationally representative short longitudinal survey. Interviewers from each province were trained comprehensively. The standard definition of seven high-burden conditions (acute myocardial infarction [MI], heart failure [HF], diabetes mellitus [DM], stroke, chronic obstructive pulmonary (COPD) disease, major depression, and end-stage renal disease [ESRD]) helped customize a protocol for disease identification. With a 3-month follow-up window, the participants answered pre-specified questions four times. The expert panels developed a questionnaire in four modules (demographics, health status, utilization, cost, and quality). The expert panel chose an inclusive set of quality indicators from the current literature for each condition. The design team specified the necessary elements in the survey to calculate the cost of care for each condition. The utilization assessment included various services, including hospital admissions, outpatient visits, and medication. RESULTS: Totally, 156 specialists and 78 trained nurses assisted with patient identification, recruitment, and interviewing. A total of 1666 patients participated in the study, and 1291 patients completed all four visits. CONCLUSION: The IQCAMP study was the first healthcare utilization, cost, and quality survey in Iran with a longitudinal data collection to represent the pattern, quantity, and quality of medical care provided for high-burden conditions.

Objective: Coronavirus disease 2019 (COVID-19) was first reported in Iran in February 2020 and then quickly spread to many cities. Different factors contribute to the numerous psychological problems of this pandemic in patients, healthcare workers and the community. This study investigated the prevalence of perceived stress, anxiety and depression in COVID-19 patients hospitalized between March and April 2020 and revealed associations of these factors with social support received from family. Method : In this cross-sectional study, patients with COVID-19 admitted between 21st of March and 22nd of April 2020 were evaluated by three questionnaires: Anxiety and depression were evaluated using the hospital anxiety and depression scale (HADS), stress levels were evaluated using the four-item perceived stress scale (PSS-4) and family support was evaluated using the perceived social support scale-family (PSS-Fa). In addition to obtaining prevalence of the noted psychological disorders and their relationship with demographic details, relationship of stress, anxiety and depression with family support was also investigated using the Pearson's correlation coefficient. Results: Participants comprised 100 COVID-19 patients (38 females and 62 males). Findings suggested high levels of perceived stress in 26% of the participants, anxiety symptoms existed in 29% and borderline conditions existed in 17%. Moreover, depressive and its borderline symptoms were respectively observed in 17% and 23%. Family support was found to negatively and significantly correlated with anxiety (Pearson correlation = -0.249, P < 0.05) and depression. (Pearson correlation = -0.221, P < 0.05). Conclusion: Given the high prevalence of anxiety and depression in hospitalized COVID-19 patients, it is recommended to further focus on non-clinical interventions, such as providing psychological first aids, boosting psychological resilience, and enabling greater family support, in efforts to prevent transformation of these psychological symptoms into long-term psychological disorders.
RESUMEN
Systemic sclerosis is a rare autoimmune disorder that potentially affects nearly every organ of the body. Malignancies are one of the most common non-systemic sclerosis related cause of mortality. There are controversial findings regarding the cervical cancer rate among these patients, but prolonged immunosuppressive medication makes them more susceptible to cervical cancer. In the present study, we have aimed to investigate the cervical cancer screening result and the Pap test non-adherence risk factors among systemic sclerosis patients. This cross-sectional study was conducted on 100 systemic sclerosis patients. The clinicodemographic variables in addition to cervical cancer risk factors were obtained from the patients. Pap test performed using the liquid-based method. The non-adherence risk factors were determined by univariate and multivariate logistic regression analysis. Benign inflammatory and atrophic changes were reported in 26 and 5%, respectively. None of the cases had abnormal cytological finding. Twenty-two percent of the participants were a routine Pap test performer. According to the multivariate model, higher age was associated with Pap test non-adherence [odds ratio (95% confidence interval): 1.058 (1.010-1.108) and P-value: 0.018]. In the present study, we have shown that compliance with Pap test performing is extremely low among Iranian systemic sclerosis patients. In addition, we have demonstrated that older age is a risk factor for non-adherence. These findings highlighted the crucial role of the physicians in motivating the patients toward cancer screening.
