Toxocariasis is a consequence of human infection by Toxocara larvae. There are symptomatic (visceral, ocular) and asymptomatic course of toxocariasis. The ocular form is very rare. We present a 6-year-old patient who developed an ocular form of toxocariasis caused by Toxocaracati. He demonstrated lesions in the peripheral retina of the right eye. White granuloma was present in the superior peripheral retina. A positive immunological assay for toxocariasis essentially completed the outcomes. On the basis of clinical manifestations and conducted examinations, a diagnosis of ocular form of toxocariasis was established. Albendazole and corticosteroids were applied in treatment. Current results clearly highlight the usefulness of excretory-secretory antigens derived from larvae of Toxocara cati for the fine diagnosis ocular larva migrans caused by Toxocara larvae.

Background:
Caregivers of hemodialysis patients spend a large amount of time providing care to these patients while tolerating fatigue and stress. This study evaluated a family-centered empowerment program on the care burden and self-efficacy of hemodialysis patient caregivers based on social cognitive theory.
Methods:
In this randomized clinical trial, 70 family caregivers of hemodialysis patients in Isfahan, Iran, were selected and randomly allocated to intervention and control groups, in 2015–2016. Two questionnaires were used to collect the family caregivers’ characteristics, care burden, and self-efficacy, and patients’ negative and positive outcomes expectancies. Data were analyzed using SPSS before, immediately after, and 2 months after the intervention.
Results:
There was no significant difference in the mean scores of care burden, positive outcomes expectancies, negative outcomes expectancies, and self-efficacy between the two groups before the intervention. However, there were significant differences in the post-test and follow-up data analyses (P<0.05).
Conclusion
Given the degenerative nature of chronic kidney disease, it can be considered as a source of long-term and chronic stress for caregivers. Therefore, by implementing an empowerment program, caregiving behaviors can be improved, positive outcomes expectancies can be increased, and negative outcomes expectancies can be reduced.

BACKGROUND: Nowadays, stroke leads to a significant part of the adult mortality and morbidity and also it could result in some neurological deficits in the patients' lives. Cell therapy has opened a new approach to treat the brain ischemia and reduce its terrible effects on the patients' lives. There are several articles which show that the cell therapy could be beneficial for treating brain stroke. In this study, we have planned to present a new cell therapy method for stroke by administration of Mesenchymal stem cells and differentiated neural stem cells without astrocytes. METHOD AND MATERIALS: The Mesenchymal stem cells were isolated from tibia and femur of a 250~300 g rat and they were cultured in DMEM/F12, 10% fetal bovine serum, 1% Pen/Strep. Neural stem cells were isolated from 14 days rat embryo ganglion eminence and were cultured in NSA media containing Neurobasal, 2% B27, bFGF 10 ng/ml and EGF 20 ng/ml after 5 days they formed some neurospheres. The isolated neural stem cells were differentiated to neural lineages by adding 5% fetal bovine serum to their culture media. After 48 hours the astrocytes were depleted by using MACS kit. RESULTS: The group that received Mesenchymal stem cells systemically and differentiated neural stem cells without astrocytes had the best neurological outcomes and the least infarct volume and apoptosis. It could be understood that this cell therapy method might cause almost full recovery after brain stoke. CONCLUSION: Using combination cell therapy with Mesenchymal stem cells and differentiated neural stem cells with removed astrocyte could provide a novel method for curing brain stroke.

OBJECTIVES:
The oocysts of the Toxoplasmatinae subfamily (Neospora caninum, Hammondia hammondi and H. heydorni, and Besnoitia besnoiti) are morphologically similar to Toxoplasma gondii, and indistinguishable from each other. This study investigated the prevalence of the Toxoplasmatinae subfamily in dog and cat fecal samples using a nested polymerase chain reaction method.
METHODS:
Overall, 200 fecal samples from domestic dogs (n=120) and cats (n=80) were collected from 15 farms in northern Iran. The samples were homogenized in 2.5% potassium dichromate solution and subsequently concentrated with sucrose solution. DNA was extracted from samples using a genomic DNA kit. Specific primers and the 18S rDNA gene were used to screen and detect all Toxoplasmatinae oocysts.
RESULTS:
Overall, 2.5% (3 of 120) and 22.5% (18 of 80) of the fecal samples collected from dogs and cats were infected with Toxoplasmatinae. In dogs, 2 samples were positive for N. caninum and 1 sample was positive for T. gondii. In cats, all 18 positive samples belonged to T. gondii. No contamination with H. heydorni was observed in dog fecal samples or H. hammondi and B. besnoiti in cat fecal samples. A phylogenetic analysis revealed that the T. gondii (cat) and N. caninum (dog) found had similarities with parasites reported from other regions of the world.
CONCLUSIONS
This is the first study to provide data on the epidemiology of Toxoplasmatinae oocysts in Iran. The findings suggest that public-health monitoring for the effective control of feces from cats and dogs and improved pet hygiene habits are needed.

Background:
This study aimed to develop and assess the psychometric features of the Physical Activity at Workplace Questionnaire (PAWPQ) based on the Social Cognitive Theory (SCT) to evaluate employees' physical activity (PA) behaviors at the workplace.
Methods:
This psychometric cross-sectional study was conducted on 455 employees working in one of the gas refineries in Iran. The participants were selected using the proportional stratified sampling method in 2019. The data collection tools were a demographic information questionnaire, the short form of the International Physical Activity Questionnaire (IPAQ), and a questionnaire developed based on the SCT, whose psychometric features were confirmed in terms of validity and reliability. Data were analyzed using SPSS22 and AMOS20 software.
Results:
The first version of PAWPQ-SCT had 74 items. After evaluating content and face validity, nine items were removed. The results of the content validity index (0.98), content validity ratio (0.86), and impact score (3.62) were acceptable for the whole instrument. In exploratory factor analysis, after removing seven items—58-item final version of the scale—six factors could explain 73.54% of the total variance. The results of structural equation modeling showed the acceptable fit of the model into the data (RMSEA = 0.052, CFI = 0.917, NFI = 0.878, TLI = 0.905, IFI = 0.917, CMIN/DF = 2.818). Cronbach's alpha coefficient and Intraclass Correlation were 0.90 and 0.86, respectively.
Conclusion
This study confirmed that the psychometric features of the 58-item final version of PAWPQ-SCT constructs were acceptable in a sample of Iranian employees. This questionnaire can be used as a valid and reliable tool to evaluate Iranian employees' PA behaviors and develop effective educational interventions for workers and managers.

OBJECTIVES: Brain stroke is the second most important events that lead to disability and morbidity these days. Although, stroke is important, there is no treatment for curing this problem. Nowadays, cell therapy has opened a new window for treating central nervous system disease. In some previous studies the Mesenchymal stem cells and neural stem cells. In this study, we have designed an experiment to assess the combination cell therapy (Mesenchymal and Neural stem cells) effects on brain stroke. METHOD AND MATERIALS: The Mesenchymal stem cells were isolated from adult rat bone marrow and the neural stem cells were isolated from ganglion eminence of rat embryo 14 days. The Mesenchymal stem cells were injected 1 day after middle cerebral artery occlusion (MCAO) and the neural stem cells transplanted 7 day after MCAO. After 28 days, the neurological outcomes and brain lesion volumes were evaluated. Also, the activity of Caspase 3 was assessed in different groups. RESULT: The group which received combination cell therapy had better neurological examination and less brain lesion. Also the combination cell therapy group had the least Caspase 3 activity among the groups. CONCLUSIONS: The combination cell therapy is more effective than Mesenchymal stem cell therapy and neural stem cell therapy separately in treating the brain stroke in rats.

Annals of Coloproctology 2024;40(5):506-514
Purpose:
This study aimed to investigate the efficacy of hydrocortisone enema in preventing radiation proctitis in patients with rectal cancer undergoing short-course radiotherapy (SCRT).
Methods:
This phase II randomized controlled trial enrolled patients with newly diagnosed locally advanced rectal cancer (clinically staged T3–4 and/or N1–2M0). Participants received a median of 4 cycles of neoadjuvant chemotherapy (capecitabine plus oxaliplatin) followed by 3-dimensional conformal SCRT (25 Gy in 5 fractions). Patients were randomly assigned to receive either a hydrocortisone enema (n=50) or a placebo (n=51) once daily for 5 consecutive days during SCRT. The primary endpoint was the incidence and severity of acute proctitis.
Results:
Of the 111 eligible patients, 101 were included in the study. Baseline characteristics, including sex, age, performance status, and tumor location, were comparable across the treatment arms. None of the patients experienced grade 4 acute gastrointestinal toxicity or had to discontinue treatment due to treatment-related adverse effects. Patients in the hydrocortisone arm experienced significantly less severe proctitis (P<0.001), diarrhea (P=0.023), and rectal pain (P<0.001) than those in the placebo arm. Additionally, the duration of acute gastrointestinal toxicity following SCRT was significantly shorter in patients receiving hydrocortisone (P<0.001).
Conclusion
Hydrocortisone enema was associated with a significant reduction in the severity of proctitis, diarrhea, and rectal pain compared to placebo. Additionally, patients treated with hydrocortisone experienced shorter durations of gastrointestinal toxicity following SCRT. This study highlights the potential benefits of hydrocortisone enema in managing radiation-induced toxicity in rectal cancer patients undergoing radiotherapy.
