Identification of latent tuberculosis (TB) infection is important in kidney transplant candidates. Due to the absence of a gold standard, both tuberculin skin test (TST) and interferon‑gamma release assays (IGRA) are used to screen patients. The aim of this study was to evaluate the agreement of these two tests in patients undergoing renal transplantation.

Two hundred kidney transplant candidates at a referral center in 2014–2017 were included in this study. TST and Quantiferon‑Gold (QFT‑G) tests were performed for all patients before transplantation. In case of a positive result in any of the tests, patients were administered a 9‑month prophylaxis treatment using isoniazid. Cohen’s kappa coefficient (k) test was used to determine the agreement between the two tests.

The mean age of patients was 40.72 ± 18.33. Nine (4.5%) patients had positive TST and 16 (8%) had positive IGRA. Concordance of the two tests was evaluated as medium (κ = 0.44 and P < 0.001). No association was found between the underlying causes of renal failure and skin test positive or IGRA. The tests showed a poor agreement among diabetics, candidates of re‑transplantation, and those who were on dialysis for longer than a year (κ < 0.20).

TST or IGRA can be used to screen TB in kidney transplant candidates with a moderate agreement. However, we suggest using both TST and QFT‑G in diabetics, re‑transplant candidates, and those on dialysis for >1 year.

Illegal abortion is a common way to terminate unintended pregnancy. It may be associated with severe complications and may raise maternal mortality and morbidity rate. Illegal abortion is one of the important concerns in health system. In our study, we consider illegal abortion claims in Medical Council court in the suburbs of Tehran.

A retrospective study was conducted. Data were extracted from registered judicial complainant cases of illegal abortion in Shahriyar medical court, Iran, during 2009–2017.

There were 751 registered claims during 2009–2017. Among them, a total of 95 gynecological claims were included in the study. Four (4.2%) registered claims were illegal abortion with severe complications such as peritonitis, rupture of uterine, small intestine, rectum, and mesentery perforation. Three cases had consumed misoprostol (prostaglandin E2) and one case had used prostaglandin E1 before curettage. Misoprostol was also used significantly more frequently than other methods for abortion before curettage (P < 0.05). Minor and short‑term complications did not registered.

The feature of claims showed that only severe morbidity and complications were registered in medical court. The definition of illegal abortion as a criminal act can be one of the factors of decreasing of abortion’s complication claims.

This study was conducted to evaluate CD30 expression in minimum residual disease after chemotherapy in B‑acute lymphoblastic leukemia (B‑ALL).

This was a cross‑sectional study on 30 new cases of B‑ALL between 2018 and 2019. We checked CD30 expressions in fresh bone marrow aspirates by flow cytometry. After 28 days of routine chemotherapy, we calculated minimal residual disease in CD30 positive and negative patients and compare them by Kolmogorov–Smirnov test.

Thirty patients with B‑ALL with a mean age of 15.62 ± 20.488 were included in the study. CD30 marker was positive in about 10 patients and was negative in about 20 participants. Mean blast count in baseline in CD30 positive group was 77 ± 7.88%, in negative group was 76.3 ± 17.78 % (P = 0.292). After 28 days of chemotherapy mean minimal residual disease (MRD) was 1.07 ± 3.754 in the negative group, 0.12 ± 0.034 in the positive group (P = 0.025).

Lower MRD on day 28 after chemotherapy was seen in B‑ALL patients with baseline CD30 expression

Anesthesiologists should obtain the best technique for cesarean section (CS). This study designed to compare the effect of general anesthesia (GA) and spinal anesthesia (SA) on immune system function in elective CS.

This descriptive study was performed on forty candidates for elective CS. They were randomly divided into GA and SA groups. The serum concentrations of interleukin (IL)‑4, IL‑6, IL‑10, and IL‑17 and interferon‑gamma (IFN‑γ) were measured using ELISA method prior to anesthesia (T0), immediately after the uterine incision (T1), 2 h post CS (T2), and 24 h post CS (T3). Data were analyzed using descriptive statistics and Chi‑square, independent t‑test, and repeated measures.

No significant differences were observed between the GA and SA groups regarding the serum levels of IL‑4, IL‑6, IL‑10, IL‑17, and IFN‑γ. The serum levels of transforming growth factor beta (TGF‑β) in the SA group were significantly (P = 0.003) more than that of the GA group at T3.

According to the angiogenesis properties of TGF‑β, it seems that SA probably affects the rate of recovery more than that of the GA.

In this study, we investigated several socioeconomic, clinical, and psychological factors associated with medication adherence in a sample of Iranian patients with inflammatory bowel disease (IBD).

This study was conducted on 110 IBD patients from 2013 to 2014 in Isfahan, Iran. The patients were invited to complete three anonymous questionnaires including the Hospital and Anxiety Depression Scale (HADS) for assessing the levels of anxiety and depression; IBD Questionnaire‑Short Form (IBDQ‑9) for the quality of life; and a visual analog scale assessing the medication adherence. A self‑assessment adherence rate of more than 80% was considered “appropriate adherence.”

Overall, 99 patients completed the questionnaires. Among them, 77.8% reportedly adhered to their medications. There was no statistical difference between adherence and nonadherence rates in terms of gender, educational status, disease type, disease severity, and family history of IBD. Conversely, single patients (100% vs. 74.1%; P = 0.03), nonsmokers (79.4% vs. 0.0%; P = 0.04), patients receiving immunosuppressive drugs (100% vs. 71.9%; P = 0.01), and corticosteroids (95.1% vs. 65.5%; P = 0.01) were more likely to be adhered than their counterparts. No differences emerged in terms of the mean HADS scores in either of the sexes. The mean IBDQ‑9 score was significantly higher in adhered patients only in females (31.08 ± 11.6 vs. 24.7 ± 9.1; P = 0.04) but not in males.

The adherence rate in our study is almost similar to developed countries. Single marital status, not smoking, receiving corticosteroids and immunosuppressive drugs, and higher IBDQ‑9 score in females are associated with higher adherence rate.

Follow‑up studies have shown an increased risk of thyroid dysfunction in individuals with normal serum thyroid‑stimulating hormone (TSH) levels. Furthermore, the possible consequences of minor differences in thyroid function (without achieving poor thyroid function) in the risk of weight gain during pregnancy are questionable, too. The production of TSH is under the hypothalamus–pituitary control, and food is one of the most effective environmental agents that control hypothalamic–pituitary– thyroid axis activity. Regarding the few available studies, we assessed the association of minor variations of TSH concentrations and nutritional status in the first trimester of pregnancy.

This cross‑sectional descriptive and analytical study was performed on 150 primiparous healthy women. Demographic and family characteristics were collected using a researcher‑administered questionnaire. Nutrients intake were extracted from a 72‑h recall, and physical activity scores were determined by the pregnancy physical activity scale.

The prepregnancy body mass index (BMI) (β =0.022, P = 0.004) and participants’ weight at 6–10 weeks of gestation (β =0.006, P = 0.024) were positively associated with TSH concentrations, while total physical activity score was negatively correlated (β = ‒0.006, P = 0.047). We did not find any significant association between TSH values and energy‑adjusted nutrients intake (P > 0.05).

We suggest that differences in TSH concentrations within normal range in the first trimester are correlated with gaining weight, physical activity level, and prepregnancy BMI. TSH concentration and consequently thyroid function may influence on gestational weight gain or vice versa.

Familial hypercholesterolemia (FH) leads to elevated low‑density lipoprotein cholesterol (LDL‑C) levels in plasma. Mutations of its related gene; apolipoprotein B (APOB) is seen in about two percent of the patient with FH. Thyroid disease is usually part of the exclusion criteria for the detection of FH which alters the lipid profile. We evaluated mutations in the APOB gene in patients with high LDL‑C levels.

Patients aged between 2 and 80 years with at least one LDL‑C level of more than 190 mg/dl were selected (120 patients) from Isfahan Laboratories. Blood samples were obtained from all patients. Genomic DNA was extracted. Primer sequences were designed by Oligo 7.60 to amplify the desired 844 bp region of exon 26 of the APOB gene containing R3500Q and R3500W variants associated with FH.

Overall, two patients showed a heterozygous form of a common pathogenic variant in exon 26 named c. 10579 C > T (R3500W, cDNA.10707), and one patient was hypothyroidism. We also recognized another nonpathognomonic variant c. 10913G > A (rs1801701, cDNA.11041) in 13 patients, two of them were hypothyroidism.

This study for the first time shows the coexistence of APOB mutation in hypothyroidism, which emphasis screening of patients with hypothyroid for FH detection.

Exercise can reduce hepcidin, tumor necrosis factor (TNF)‑α, and interleukin (IL)‑6 and improve the iron status, but the intensity of exercises is very important. This study will compare the effect of resistance training (RT) intensity on hepcidin levels, iron status, and inflammatory markers in overweight/obese girls with and without iron stores deficient.

In this quasi‑experimental study, 40 students of the University of Isfahan (18–22‑year old, with 35 > body mass index [BMI] ≥25) voluntarily participated in the study. Participants were divided into two groups with 20 participants, based on serum ferritin (>30 ng/ml or ≤30 ng/ ml). Participants in each group were randomly and equally assigned to one of the moderate or high‑intensity training groups. RT was performed 8 weeks, 4 days a week, and each session for 1 h, with an elastic band. The iron levels, hepcidin, total iron‑binding capacity, ferritin, hemoglobin, TNF‑α, and IL‑6 before and after intervention were collected with the blood samples. Two‑way analysis of variance was used to assess the impact of exercise and ferritin level and their interaction, and the paired test was utilized for test changes from baseline.

There are no significant interactions between ferritin levels and exercise intensity for the main outcomes (all P > 0.05). The significant impact of the mode of exercise was observed in TNF‑α (P < 0.05), and a significant difference between low and high levels of ferritin was observed in hepcidin (P = 0.002). Besides, in all four groups, significant decreases were observed in BMI (28.00 ± 3.00 to 27.00 ± 3.00), hepcidin (1234.02 ± 467.00 to 962.06 ± 254.00), and TNF‑α (223.00 ± 99.00 to 174.00 ± 77.00) compared to the baseline measurements (all P < 0.05).

Basal ferritin levels appear to be effective on hepcidin levels, TNF‑α, and IL‑6 after the intervention. RT with two different intense can reduce BMI, hepcidin, ferritin, and TNF‑α in all groups. It seems that performing RT reduces inflammation and hepcidin in obese/overweight participants with different iron stores.

COVID‑19 has caused significant morbidity and mortality around the world. Recent reports point toward the “cytokine storm” as core of pathogenesis in SAR‑CoV‑2‑induced acute lung injury, acute respiratory distress syndrome (ARDS), coagulopathy, and multiorgan failure. We have presented clinical data here wherein cytokine levels in COVID‑19 patients do not match typical cytokine storm seen in ARDS. Interestingly, COVID‑19 patients in early disease present with hypoxemia with no significant respiratory dysfunction. In addition, it is reported that hospitalized COVID‑19 patients have a high incidence of thrombotic complications, especially involving the pulmonary vasculature. We hypothesized that core to pathogenesis of COVID‑19 is the dysregulation of neutrophils, which culminates in excessive release of neutrophil extracellular traps (NETs). Recently, an increasing amount of NETs have been seen in sera of severe COVID‑19 patients. We have discussed here mechanisms involved which lead to thrombogenesis and vasculitis because of excessive release of NETs.

Dyslipidemia (DL) is an important risk factor of coronary artery disease (CAD). We evaluated DL prevalence and its 5‑year incidence rate in southeastern Iran, to assess the severity and growth rate of this CAD risk factor in the region.

This study was a part of the Kerman CAD Risk Factors Study Phase 2 (2014–2018) among 9996 individuals aged 15–80 years, from whom 2820 individuals had also participated in Phase 1 (2009–2011). In mg/dl, cholesterol ≥240 and/ or low‑density lipoprotein cholesterol ≥160 and/or high‑density lipoprotein cholesterol <40 for men and <50 for women and/ or triglyceride >200 were defined as DL.

The lipid profile of 9911 persons was analyzed. Overall 19.6% had borderline cholesterol and 6.4% suffered from hypercholesterolemia. 56.6% of the population (62.5% of females vs. 48.5% of males) suffer from DL, from whom 73.4% were undiagnosed. Female gender, advanced age, obesity, hypertension, diabetes, anxiety, and depression predicted DL in the study population. The prevalence of DL was significantly lower in Phase 2 (56.6%) compared to Phase 1 (81.4%). The prevalence of undiagnosed DL (UDL) and diagnosed DL (DDL) was 40.7% and 16.2%, respectively. The 5‑year incidence rate of DL was 2.58 persons/100 person‑years (3.24 in females vs. 2.20 in males).

Although there were promising signs of a reduction in DL and increase in DDL in the last 5 years, a high percentage of the population have DL yet, from whom mostly are undiagnosed. DL was significantly associated with other CAD risk factors. Therefore, the health‑care management system should improve its strategies to reduce the health burden of DL.

The coronavirus disease 2019 (COVID‑19) presents various phenotypes from asymptomatic involvement to death. Disseminated intravascular coagulopathy (DIC) is among the poor prognostic complications frequently observed in critical illness. To improve mortality, a timely diagnosis of DIC is essential. The International Society on Thrombosis and Hemostasis (ISTH) introduced a scoring system to detect overt DIC (score ≥5) and another category called sepsis‑induced coagulopathy (SIC) to identify the initial stages of DIC (score ≥4). This study aimed to determine whether clinicians used these scoring systems while assessing COVID‑19 patients and the role of relevant biomarkers in disease severity and outcome.

An exhaustive search was performed according to Preferred Reporting Items for Systematic Reviews and Meta‑Analyses, using Medline, Embase, Cochrane, CINAHL, and PubMed until August 2020. Studies considering disease severity or outcome with at least two relevant biomarkers were included. For all studies, the definite, maximum, and minimum ISTH/SIC scores were calculated.

A total of 37 papers and 12,463 cases were reviewed. Studies considering ISTH/SIC criteria to detect DIC suggested a higher rate of ISTH ≥5 and SIC ≥4 in severe cases and nonsurvivors compared with nonsevere cases and survivors. The calculated ISTH scores were dominantly higher in severe infections and nonsurvivors. Elevated D‑dimer was the most consistent abnormality on admission.

Higher ISTH and SIC scores positively correlate with disease severity and death. In addition, more patients with severe disease and nonsurvivors met the ISTH and SIC scores for DIC. Given the high prevalence of coagulopathy in COVID‑19 infection, dynamic monitoring of relevant biomarkers in the form of ISTH and SIC scoring systems is of great importance to timely detect DIC in suspicious patients.

The cause of coronavirus disease 2019 (COVID‑19) is a virus which can lead to severe acute respiratory syndrome‑CoV‑2 (SARS‑COV‑2). There are evidences of involvement of immune system in pathogenesis of this disease. We investigated the presence of various vasculitis‑associated autoantibodies and complement levels in patients with COVID‑19.

Patients with severe or critical type of COVID‑19 were evaluated for symptoms, signs, and laboratory tests of vasculitis syndromes including rheumatoid factor (RF), antinuclear antibody (ANA), anti‑double‑stranded DNA, c and p anti‑neutrophilic cytoplasmic antibody (c ANCA and P ANCA), and complement levels.

The study was performed in forty patients with severe or critical illness. The mean age of the participants was 48.5 ± 9.8 years. All patients had pulmonary involvement in lung computed tomography scans. Vasculitis laboratory test results included RF in two patients, ANA in three patients, and ANCA in one patient. Seventeen (42.5%) patients had hypocomplementemia in one or more complement tests. Four patients expired, of whom three had a decrease in complement level.

Decrease in complement levels may predict a critical state of COVID‑19 disease. Therefore, measuring its levels may be of great benefit in making earlier decisions to initiate disease‑suppressing treatments including corticosteroids.
