Spiritual intelligence dimensions and life regard index in Iranian veterans suffering post-traumatic stress disorder with and without substance abuse history

Post-traumatic stress disorder (PTSD) among some combatants was one of the Iran–Iraq War problems. Moreover, this disorder has a high comorbidity with other kinds of disorders like substance abuse as in the case of some Iran–Iraq War veterans. This study examined the effect of some individual psychological factors on these veterans' substance abuse. Among these factors, this study seeks to find the existence of difference between spiritual intelligence and life regard index of veterans with no history of substance abuse comparing with veterans with substance abuse history. Therefore, 120 PTSD veterans hospitalized in Shahid Rajaee Hospital in Isfahan, Iran, were studied during a 9-month period. Half were with and half were without substance abuse; they were also matched on demographic characteristics. There was a significant difference between spiritual intelligence and life regard index and also spiritual life and fulfillment sub-scales of those with history of substance abuse and those without. Conversely, no significant difference was observed on sub-scales of understanding, relationship with the Origin of Essence and fulfillment. Therefore, it can be concluded that dimensions of spiritual intelligence and positive life regard development could help to deter substance abuse, as well as accelerate recovery.     

Comparisons of American,Israeli, Italian and Mexican physicians and nurses on the total and factor scores of the Jefferson scale of attitudes toward physician-nurse collaborative relationships

This cross-cultural study was designed to compare the attitudes of physicians and nurses toward physician-nurse collaboration in the United States, Israel, Italy and Mexico. Total participants were 2522 physicians and nurses who completed the Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (15 Likert-type items, (Hojat et al., Evaluation and the Health Professions 22 (1999a) 208; Nursing Research 50 (2001) 123). They were compared on the total scores and four factors of the Jefferson Scale (shared education and team work, caring as opposed to curing, nurses, autonomy, physicians' dominance). Results showed inter- and intra-cultural similarities and differences among the study groups providing support for the social role theory (Hardy and Conway, Role Theory: Perspectives for Health Professionals, Appelton-Century-Crofts, New York, 1978) and the principle of least interest (Waller and Hill, The Family: A Dynamic Interpretation, Dryden, New York, 1951) in inter-professional relationships. Implications for promoting physician-nurse education and inter-professional collaboration are discussed.     

Systemic oxygen therapy versus oral enalapril for treatment of diabetic macular ischemia: a randomized controlled trial

The purpose of this study was to evaluate the structural and functional effects of systemic oxygen therapy and enalapril in patients with diabetic macular ischemia (DMI). This randomized clinical trial consisted of 105 eyes with DMI divided into three groups. Group I received systemic oxygen by face mask at a flow rate of 10 L/min; Group II received 5 mg enalapril daily; and Group III received placebo tablets for 3 months. Best-corrected visual acuity (BCVA), central macular thickness (CMT) measured by optical coherence tomography (OCT), extent of foveal avascular zone (FAZ) on fluorescein angiograms, and electroretinograms (ERG) were obtained at baseline and after 3 and 6 months. Overall, 102 patients completed the study. Baseline characteristics were not significantly different among groups. Significant improvement in BCVA and decrease in CMT and FAZ occurred at months 3 and 6 in oxygen group compared to deterioration in enalapril and control groups (All P values <0.001). ERG parameters were significantly better in oxygen group compared to enalapril group at months 3 and 6 and better than those in control group at month 3. Normobaric oxygen therapy for 3 months in DMI decreased CMT and FAZ and improved BCVA and ERG parameters. Enalapril did not show any favorable effect.     

An overview of the biological and multifunctional roles of IL-38 in different infectious diseases and COVID-19

Undoubtfully, the normal immune system can make a potential response to variable pathogens and neutralize or kill them depending on the type of infection through innate and acquired immunity. Cytokines have poly-peptide nature and are considered as signaling molecules that could amplify or alleviate immune responses besides their other biological functions. Interleukin 38 (IL-38) is a member of the IL-1 family cytokine that, however, its anti-inflammatory role has been observed in different autoimmune diseases like systemic lupus erythematosus (SLE), psoriasis, and Sjogren’s syndrome; there is a controversy about the cytokine pro-inflammatory function. In the current review, we skimmed IL-38 structure, signaling mechanism, and its immunological functions, IL-38-producing immune cells. Also, we argued about the role of this cytokine in viral infections including hepatitis B (HBV), hepatitis C (HCV), influenza (Flu), and COVID-19. Also, it illustrated the IL-38 protective effects on sepsis. Moreover, we explained the modulatory role of IL-38 in the COVID-19 cytokine storm.

     

The SMILES trial: an important first step

The SMILES trial was the first intervention study to test dietary improvement as a treatment strategy for depression. Molendijk et al. propose that expectation bias and difficulties with blinding might account for the large effect size. While we acknowledge the issue of expectation bias in lifestyle intervention trials and indeed discuss this as a key limitation in our paper, we observed a strong correlation between dietary change and change in depression scores, which we argue is consistent with a causal effect and we believe unlikely to be an artefact of inadequate blinding. Since its publication, our results have been largely replicated and our recent economic evaluation of SMILES suggests that the benefits of our approach extend beyond depression. We argue that the SMILES trial should be considered an important, albeit preliminary, first step in the field of nutritional psychiatry research.     

Sperm retrieval rate and reproductive outcome of infertile men with azoospermia factor c deletion

To evaluate the success rate in sperm retrieval (SR) through microdissection testicular sperm extraction (micro‐TESE) in infertile azoospermia factor c (AZFc)‐deleted men and determining their reproductive outcomes following ICSI, medical records of couples with AZFc‐deleted male partners were reviewed on patient's age, serum hormone levels, karyotype, testicular pathology and pregnancy outcomes. A comparison on age and serum hormone level was conducted between groups with positive and negative sperm retrieval in both azoospermic and oligozoospermic AZFc‐deleted men. Of 225 who had AZFc deletion, 195 cases followed clinical treatments. From 195 cases, 116 were azoospermic, 79 were oligozoospermic. Pathology profile was available in 103 of 195 subjects which the predominant trait was SCOS and was seen in 66.9% of cases (69 of 103). Success rate of sperm retrieval in azoospermic patients who underwent micro‐TESE was 36.3% (28/77). Forty‐three oligozoospermic and 17 azoospermic patients started ART cycle. Pregnancy rate in oligozoospermic group was 35.4% (17 cases), whilst there was no clinical pregnancy in azoospermic group. In conclusion, the pregnancy and delivery in oligozoospermic patients with AZFc deletion are comparable with other studies, but despite of sperm retrieval in azoospermic patients with AZFc deletion, the chance of pregnancy or delivery in these patients was very low.
