Hospitals, as one of most important subsectors in human societies, are responsible for providing safe and effective medical services to clients. But sometimes these hospitals are the source of injury and death in patients by creating medical errors. In this systematic review study, the application of human factor analysis and classification system (HFACS) method in the classification of medical errors was investigated. Major electronic databases including Scopus, Web of Science, and MEDLINE were searched. All studies that investigated the application of HFACS method for coding, causation, and classification of medical errors and adverse events conducted from 2001 until February 2021 were included. A total of 108 articles were found. Due to duplication, 18 studies were removed from the review list. After reading the titles and abstracts, 50 of these publications were excluded because they had objectives different from this review. The remaining 40 publications were retrieved for further assessment. Of these, 28 publications were excluded because it did not meet the inclusion criteria. Finally, 12 articles remained for the final systematic review. We found that in 65% of the selected studies, preconditions for unsafe acts have been the major causal level of medical errors and adverse events. In the majority of the studies, communication and coordination, adverse mental states, physical environment, crew resource management, and technological environment have also been recognized as the most important causal categories in this study. As a result, to prevent medical errors and adverse events, the main focus should be on controlling the preconditions for unsafe acts including personnel factors, operator conditions, and environmental factors.

Infections with herpes simplex virus type 2 (HSV‑2) and varicella‑zoster virus (VZV) are associated with serious maternal and neonatal health consequences. The literature review reveals a research gap regarding the seroprevalence of HSV‑2 and VZV among women of reproductive age in Mashhad, Northeast of Iran. The present study aims to evaluate the seroprevalence of these viruses among a group of women in Mashhad, Iran.

Sera were collected by health center personnel using a cluster sampling method from healthy women with specific age characteristics residing in three distinct socioeconomic regions of the city. The participants, aged 20–35, were divided into three groups (20–25, 26–30, and 31–35 years). The levels of VZV and HSV‑2 IgG antibodies were evaluated using commercial ELISA kits. Subsequently, the results were analyzed using SPSS software.

A total of 93 women were included in the study. Anti‑HSV‑2 IgG antibody was detected in 3 out of 93 participants (7.5%), while anti‑VZV IgG antibody was found positive in 80 out of 93 individuals (83.3%). The HSV‑2 positive cases were concurrently positive for the VZV antibody. There was no significant difference in the positivity of anti‑HSV‑2 and anti‑VZV antibody positivity within age groups or socioeconomic status (P > 0.05).

The high seroprevalence of VZV among nonvaccinated participants indicates a widespread presence of the virus and underscores its potentially serious impact on community health. Therefore, it is recommended that a VZV vaccination program be considered by the health system. Furthermore, the reactivation of latent HSV‑2, whether symptomatic or asymptomatic, during pregnancy should not be disregarded as a life‑threatening threat

Ventilator‑associated pneumonia (VAP) is one of the most common nosocomial infections. The role of probiotics in preventing VAP is still questionable. This study aimed at evaluating the effect of synbiotic FamiLact 2plus on the prevention of VAP in patients admitted to the intensive care unit (ICU).

A total of 80 mechanically ventilated patients were included and divided into two groups of 40. Group 1 received FamiLact 2plus, and group 2 received placebo. The outcome variables were compared, including the incidence of VAP, the time interval between the onset of ventilation and VAP, the duration of mechanical ventilation, and the length of stay in the ICU.

VAP is documented in four patients (10%) in group 1 and 11 patients (27.5%) in group 2 (P = 0.045). The length of stay in the ICU in group 1 was significantly shorter than in group 2, and the time interval between the start of intubation and the onset of VAP in group 1 was longer than in the placebo group. During the intervention, 15 patients in group 1 (37.5%) and 26 patients in group 2 (65%) developed diarrhea, which was a significant difference (P = 0.02).

Synbiotic is associated with a reduction in the incidence of VAP as well as a reduction in ICU stay and delayed VAP.

Bachground: Noise is one of the most important harmful factors in the environment. There are limited studies on the effect of noise loudness on brain signals and attention. The main objective of this study was to investigate the relationship between exposure to different loudness levels with brain index, types of attention, and subjective evaluation.

Four noises with different loudness levels were generated. Sixty‑four male students participated in this study. Each subject performed the integrated visual and auditory continuous performance test (IVA-2) test before and during exposure to noise loudness signals while their electroencephalography was recorded. Finally, the alpha‑to‑gamma ratio (AGR), five types of attention, and the subjective evaluation results were examined.

During exposure to loudness levels, the AGR and types of attention decreased while the NASA‑Tax Load Index (NASA‑TLX) scores increased. The noise exposure at lower loudness levels (65 and 75 phon) leads to greater attention dysfunction than at higher loudness. The AGR was significantly changed during exposure to 65 and 75 phon and audio stimuli. This significant change was observed in exposure at all loudness levels except 85 phon and visual stimuli. The divided and sustained attention changed significantly during exposure to all loudness levels and visual stimuli. The AGR had a significant inverse correlation with the total score of NASA‑TLX during noise exposure.

These results can lead to the design of methods to control the psychological effects of noise at specific frequencies (250 and 4000 Hz) and can prevent non‑auditory damage to human cognitive performance in industrial and urban environments.

Context:

 Growing needs mandates economic growth. Entrepreneurship policies play a significant role in achieving productive employment and sustainable development for the health and wealth of society. Aims: This study is conducted to find the accordance of this document with the basic theory of the global alphabet model of entrepreneurship on the one hand and a comparison to the real entrepreneurial and economic achievements as social determinants of health (SDOH) on the other hand.

Methods and Material: 

This research is a quantitative and qualitative content analysis of entrepreneurship documents in the health sector of Iran, using the basic theory of the global alphabet model as our target. We reviewed the Work Bank and Global Entrepreneurship Monitor (GEM) reports as world indicators to compare whether our entrepreneurship policies have been successful.

Statistical Analysis: 

MAXQDA is a software program designed for computer-assisted qualitative and mixed methods data, text and multimedia analysis in academic, scientific, and business institutions.

Results:

 The findings showed that the retelling of the word employment is more dominant than entrepreneurship. Imbalanced attention is paid to the components of the standard global alphabet model, and a downhill regression is seen in almost all aspects of entrepreneurial results.

Conclusions: 

The written health policies have not been effective in promoting the development of health by wealth.

Endothelial function plays an important role in the protection of vessels from atherosclerosis. Detection of endothelial dysfunction by non‑invasive methods (flow‑mediated dilation) and its association with other imaging modalities (calcium score in coronary computed tomography [CT] angiography) is still controversial. In this study, we aim to investigate the association between endothelial function evaluated by flow‑mediated dilation (FMD) and calcium score evaluated by coronary CT.

In this cross‑sectional study, 124 patients with known coronary artery disease (CAD, positive calcium score) were enrolled. FMD as an indicator of endothelial function was evaluated in these participants. FMD less than 7.1%was considered abnormal. Correlation between calcium score and severity of calcification(calcium score above 100 considered as the cutoff point of the high score) and glow‑mediated dilation was obtained using the linear regression model.

The association between calcium score and FMD was strongly significant (P < 0.001). Among individuals with low calcium scores, only 15 (18.1%) had abnormal FMD findings, but the majority of individuals with high calcium scores (95.1%) had abnormal FMD findings.

Our findings provide strong evidence of association between FMD, a marker of vascular endothelial dysfunction, and intensity of coronary atherosclerosis, as assessed by the calcium score on the CCTA.
