Burden of Care in Caregivers of Iranian patients with chronic disorders: A systematic review and meta-analysis
Introduction: Caring for patients with chronic disorders can lead to different problems for caregivers in physical, psychological, social, family, and financial domains. High levels of burden of care can make caregivers vulnerable to physical and psychological conditions and influence their quality of life. Therefore, the goal of the present study was to estimate the overall percentage of burden of care in caregivers of Iranian patients with chronic disorders. Methods: A total of 25 articles published from inception to February 2019 were reviewed. Search for articles was conducted in international (Scopus, Web of Science, and PubMed) and domestic (Scientific Information Database (SID) and MagIran) databases, using the following keywords: "Caregiver,""Burden,"and "Iran,"and their possible combinations. The data were analyzed using the meta-analysis method and the random effects model. All the analyses were performed using STATA, version 14. Results: The overall percentage of burden of care in caregivers of Iranian patients with chronic disorders was 53.28 (95 CI: 46.13-60.43). The highest percentage of burden of care was related to dialysis (62.75; 95 CI: 56.11-69.38), mental disorders (58.69; 95 CI: 49.70-67.69), and Alzheimer's disease (57.07; 95 CI: 46.23-67.92), respectively; and the lowest percentage of burden of care was related to diabetes (34.92; 95 CI: 18.01-51.82). Conclusions: Caregivers of Iranian patients with chronic disorders experience high levels of burden of care, especially those caring for patients undergoing dialysis, patients with mental disorders, and patients with Alzheimer's disease. Therefore, necessary measures need to be taken by Iranian health care officials to reduce burden of care in caregivers. © 2020 The Author(s)
Increased Expression of Transforming Growth Factor-beta and Receptors in Primary Human Airway Fibroblasts from Chemical Inhalation Patients
The widespread use of sulfur mustard (SM) as a chemical warfare agent in the past century has proved its long-lasting toxic effects. Despite a lot of research over the past decades on Iranian veterans, there are still major gaps in the SM literature. Transforming growth factor (TGF-beta), a cytokine that affects many different cell processes, has an important role in the lungs of patients with some of chronic airway diseases, especially with respect to airway remodeling in mustard lung. Primary airway fibroblasts from epibronchial biopsies were cultured, and gene expression of TGF-beta 1, TGF-beta 2, TbR-I and TbR-II in fibroblasts of SM injured patients and controls were investigated. Expression of TGF-beta s and receptors was measured by RT-PCR. Protein level of TGF-beta 1 was surveyed by western blot. Our findings revealed that expression levels of TGF-beta 1, TGF-beta 2, TbR-I and TbR-II were upregulated in the airway fibroblasts of SM exposed patients in comparison with control samples. TGF-beta 1 expression was shown to be markedly increased in primary lung fibroblasts of chemically injured patients. Our novel data, suggested that over-expression of TGF-beta molecule and receptors in primary airway fibroblasts of mustard gas injured patients may be involved in progression of airway remodeling of these patients
Heritability and selection response estimation of growth rate in common carp (Cyprinus carpio) of Caspian Sea
The Common carp is the most important culture fish in the word, that can be consider as domestic fish. The Common carp of Caspian Sea is one of the economic fish, that have some morphenological differences, resistance in salt water and better quality in meet with domestic once and for using this fish in culture system, it is necessary to establish genetically parameters especially the heritability for selection purpose. The present study have been started from 2007 and lasted 3 years. The breeders were collected from the Gomishan station in south-east of Caspian Sea by fisherman and stocked in S.Rajaei fish restocking center and propagate based on the routine propagation technique in this farm. For heritability estimation a factorial crosses by 7×7 fish were done. Therefore, the fingerlings of 49 crosses were achieved, that kept first separately fiberglass tank and then in pond separately. Weight and length of fish were choice for heritability estimation. The average weight of juvenile common carp in 3 sampling stage of 90, 180 and 360 days, were 5.9, 35.7 and 84.7 gram and length of 9.6, 14.7 and 19.2 cm respectively. The heritability estimation for weight was 0.26 and length 0.25. Selection response based on selection difference by collection the more average breeders among their progeny were 36.4 g that means by selection every generation, there is about 4 percent improving in fish weight

Background: The aim of this study was to evaluate the risk factors for hospitalizations of cases with positive and negative COVID-19 tests. Methods: In this case-control study, the case and control groups consisted of 292 COVID-19 patients and 296 non-COVID-19 patients. Patients who referred to a reference laboratory in Tehran (Iran) in March 2020 were selected and interviewed. The patients were contacted by telephone and data were recorded through a questionnaire. Results: The sample of this study consisted of 588 patients (349 59% females, 239 41% males) with a mean age of 42 ± 15. The results of this study showed that comorbidities like diabetes (OR = 7.42), hypertension (OR = 4.85), asthma and respiratory diseases (OR = 5.64) in addition to symptoms including fever (OR = 6.67), chills (OR = 11.2), anorexia (OR = 11.3), dyspnea (OR = 4.8), weakness and lethargy (OR = 5.7) were the most predictive variables for hospitalization of non-COVID-19 cases. Furthermore, demographical variables like male gender (OR = 3.71), high age (>50; OR = 3.12), BMI (>25; OR = 2.37), travel (OR = 2.79), comorbidities including diabetes (OR = 5.26), hypertension (OR = 3.7) and underlying immunosuppressant patients receiving corticosteroid therapy (OR = 3.62) in addition to symptoms like anorexia OR = 2.55 and dyspnea (OR = 6.99) tend to increase the risk of hospital admission in COVID-19 patients, suggesting their predictive values for hospitalization of COVID-19 patients. Conclusion: Our results indicated that different factors tend to increase the odds of hospital admission in patients with positive and negative COVID-19 tests, suggesting their predictive values for hospitalization. © 202
Rearing of common carp (Cyprinus carpio) in fiber glass tanks with pellet feeding
The intensive culture of common carp (Cyprinus carpio) evaluated in fibreglass tanks (2*2m) with feeding on pellet during 8 weeks. The fish (n=201)of common carp selected from three treatments along with three replicates as the average of fish weight was less than 100(g )which divided into 0.05).The common pellet food was chosen for feeding from market as fish were fed by the mean of 4% of their body weight a day. The result indicated that the mean of particular growth ratio at first treatment (0.54) has higher than second treatment (0.34) but in comparison with third treatment (0.46), there was no statistically significant difference (P<0.05).Also, the conversion ratio at first treatment (5.28) and third treatment (6.09) was lower than second treatment (35.66) and third treatment (20.91) was lower than second treatment (24.24), (P<0.05). This study showed that monoculture in small scale is feasible by utilizing artificial diet, if the water quality is exposed to change. In this survey, the conversion ratio of the fish was relatively high whereas the growth rate was low

Long-term Health Outcomes Among Survivors Exposed to Sulfur Mustard in Iran
Importance: The prevalence and severity of long-term health complications after exposure to sulfur mustard are unknown. Objective: To investigate the long-term health outcomes among survivors exposed to sulfur mustard during the Iran-Iraq War. Design, Setting, and Participants: In this retrospective cohort study, late-onset health complications of 64�190 Iranian survivors exposed to sulfur mustard during the Iran-Iraq War from 1980 to 1988 were investigated using descriptive statistics. Data involving affected organs and symptom severity were extracted from the Veterans and Martyr Affair Foundation (VMAF) database from 1980 to 2019. Assessments were conducted across 3 groups depending on whether survivors were (1) evacuated and admitted (EA) to a hospital; (2) not evacuated or admitted (NEA) to a hospital; or (3) evacuation or admission status was not documented. Exposures: Analysis of chronic symptom severity following exposure to sulfur mustard. Main Outcomes and Measures: Mild, moderate, or severe rankings of symptoms in lungs, eyes, and skin of survivors exposed to sulfur mustard using data from the VMAF database. Results: Of 64�190 chemical survivors registered in the VMAF database, 60�861 met the inclusion criteria. Of the included survivors, 98.0 were male, and the mean (SD) age was 23.5 (7.7) years. Most survivors (53�675 88.2%) had no symptoms or mild lesions, and 7186 survivors (11.8%) had moderate or severe complications. Moderate to severe lung (6540 10.7%), eye (335 0.6%), or skin (725 1.2%) injuries were documented in the exposed population. The proportion of moderate plus severe late complications in eyes was 3 times as high in male survivors compared with female survivors (0.6% 95% CI, 0.53%-0.65% vs 0.2% 95% CI, 0.09%-0.73%; P�<�.001), whereas dermal complications were significantly more common in female survivors (3.9% 95% CI, 2.92%-5.11% vs 1.14% 95% CI, 1.06%-1.23%; P�<�.001). Mild lung lesions were more prevalent in the NEA group than in the EA group (73.9% 95% CI, 73.4%-74.4% vs 11.0% 95% CI, 10.6%-11.3%; P�<�.001). In the NEA group, 83.2% (n�=�23�866) developed lung injuries that were mostly mild or moderate, whereas 77% (n�=�24�766) of the EA group did not develop lung injuries (P�<�.001). Conclusions and Relevance: The present study found sex differences in the frequencies of eye and skin complications following sulfur mustard exposure, and lung complications were more prevalent years after sulfur mustard exposure than soon after exposure. Mild lung lesions were observed more frequently among sulfur mustard-exposed survivors who had not been evacuated or hospitalized than among those who had been evacuated or hospitalized. These differences may be due to physiological response or dose of exposure. Close monitoring over an extended period may be required for detection of late pulmonary complications in individuals exposed to sulfur mustard
Evaluation of quantitative and qualitative of microbial indicator the lake behind Shahid Rajaee dam of Mazandaran province (Sari)
One of the country's dams is dam Shahid Rajaee Sari. In this study it was evaluated some bacterial indices. Some bacterial parameters including total bacteria, total coliform, fecal coliform, fecal streptococci , Sulphitereducing Bacteria (SRB) in the water behind the dam Shahid Rjaee for one year at five stations (the entrance Shireenrood branches, input branch of the Sefidrood, cross the river and sweet Sefidrood in the tank, close to the Taj (zero, 15 and 30) and the output reservoir) and seven samples collected during six periods (June, July, August, September, November and February) were tested in 1391. Analysis of water samples for bacterial plate count agar medium (total bacteria count) ECC were inoculated (total coliforms and fecal), SPS (sulfite reducing bacteria) and KF (bacteria Inserts fecal streptococci) was performed using the culture surface culture method. ECC in both 37 and 44 ° C medium temperature Tc, KF and SPS at 37 ° C for 72-24 hours were incubated. The results showed that the mean log of bacteria in different months of CFU / 100ml12 / 0 ± 85/6 1n September months to CFU100ml15 / 0 ± 65/4 is variable in February, the mean total coliform Log in of the CFU / 100ml15 / 0 ± 63/4 in September to CFU / 100ml44 / 0 ± 27/3 in February are variable, the mean log Clostridium Clostridium CFU / 100ml89 / 0 ± 17 / 4 in September to CFU / 100ml13 / 0 ± 07/3 in February is variable, ranging from the mean log reduction in fecal streptococci in different months CFU / 100ml19 / 0 ± 59/3 in September CFU / 100ml17 / 0 ± 10 / 3 in February is variable. The results showed that bacterial indicator pollution load of the dam in more stations in August and September months. . Compare the results of the surface water standards indicate that indicator bacteria have been studied in the standard range. If the water behind the dam is intended to be used for drinking, it has need for more treatments during the final purification for drinking purposes
Quantitative evaluation and identification of fungi in Shahid Rajaeii Dam Lake, Mazandaran Province (Sari)
The present study is carried out to investigate the fungal species present in water of Shahid Rajaeii damlake in Sari, (Mazandaran province). Samples were taken from five stations including, Station 1: Input of Shirinrud river, station 2: Input of Sefidrud river, Station 3: The confluence of the two branches, Station 4: dam crest and stations 5: Output dam from June to February 2012. Every sample was diluted by sterile saline (10-1 and 10-2) and 0.5 mL from each dilution was cultured on SD and incubated at 27-30°C for 3-5 days. Finally, the number of colonies wasrecorded as (colony forming unit = CFU) per 100 mL. Identification of fungal agents were conducted by slide culture preparation and stained in lacto-phenol blue. The results showed that in August and February were significantly highest and lowest rates of fungal colonies were isolated from water in different stations respectively. Moreover, the number of fungal colonies in the crown and the output was significantly higher than other stations. The frequency of identified fungi were: Aspergillus species (31.4%), various types of yeast (mainly Candida) (24.2%), Penicillium sp. (19.3%), Cladosporium sp.(10.3%), Mucor sp. (5.4%), Fusarium sp. (2.9%), sterile hype (2.8%), Alternaria sp. (2.3%) and Paecilomyces sp. (1.4%)
Breeding and reproduction of grey mullet (Mugil cephalus L.)
Mazandaran and Gorgan provinces have temperate climate, thus they have more potential for aquatic animal culture. There are thousands hectare of salt and useless lands in adjacent to Caspian Sea. As these areas have provided a favorable back ground for aquatic animal culture. As a result, the successful results obtained from imported gray mullet (Mugil cephalus) culture project in north climate, it has demonstrated that the gray mullet has a good biocharacteristic for culturing in pond enclosure environment and in different aquatic conditions (fresh water, brackish water and salt water). From 1998 until 2001, the broodstock yield and gray mullet artificial propagation projects were performed by fisheries research center of Mazandaran in Ghomishan prawn culture station in adjacent to Caspian Sea (East north of Mazandaran Province). This investigation executed during two stages (phases). At first stage, the goal of this project included the survey of possibility available about matured fish as well as induction of final maturation and artificial propagation for producing of broodstock and larva. In addition, in this way, we will obtain new information about gray mullet propagation and culture as marine species. We introduce mass production in aquaculture. At present research, the possibility of broodstock yield and artificial propagation of gray mullet have investigated by gray mullet fingerlings imported from Hong kong and then they have cultured in earth ponds of Ghomishan areas during five years (1994-1998). In order to broodstock production in spring 1998, two earth ponds (0.5 hectare) were prepared. 100 specimens of fish stock (1-2.5 kg weight average and 5 years of age) placed in each pond. For providing of suitable water and nutrition, fish were fed by food containing rich protein (40%) with 3-5% body weight and maintained in water with 30-35 ppt salinity. The survey of sexual maturation was performed by sampling of sexual glands through year. There were four stages in dominant female broodstocks. This survey indicated that oocytes have emerged stage 1 (immature) from March to June, stage 2 (yolk vesicle) in September and stage 4 (yolk globule) in October. Three stages (first, second and third) of yolk formation in oocytes will occur but these stages take place in October, December and January respectively. It's obvious that oocytes will progress into the end of third stage (yolk formation) and then their growth was arrested. Ovum with 600 m diameter was observed when the water temperature declined less than 18 c and day time was short (from middle autumn to middle winter), on that time, fish were induced by hormone because lack of final maturation and ovulation, therefore, natural spawning was not occurred in pond condition. Furthermore, artificial propagation of mugil cephalus was occurred by hormonal induction. Hormonal induction was utilized by inject of many hormones (LHRH, Cph, HCG). Using different components of hormones and also their different doses obtained the best results from broodstock that the average ovum diameter was about 600 m. Several types hormones which were injected into gray mullet with two or several intermittent (24 h intervals) along with 20-25 c temperature and 30-35 ppt salinity. This condition can provide stage 4 maturity for fertilization. Totally (as whole), three intermittent fertilization was necessary for exiting of larva, larva production in first, second and third intermittents that were 2000, 2500 and 300 specimens respectively. Larva fed on chlorella algae and rotifera and they have maintained for 14-15 days. The results of obtainable research indicated the possibility of gray mullet broodstock production in cultural condition, artificial propagation and larva production. This research took place for the first time in north climate of Iran
