A qualitative study of the experiences of Iranian infertile couples after unsuccessful assisted reproductive technologies

Objectives: Assisted reproductive technologies (ARTs) give hope to some infertile couples; however, in vitro fertilization (IVF) is expensive and not subsidized by the Iranian state. More than 75% of IVF cycles in Iranian couples are unsuccessful. The aim of this paper is to describe the experiences of Iranian infertile couples after unsuccessful treatment. Materials and Methods: In this descriptive qualitative study, 36 participants including 29 Iranian infertile couples recruited after unsuccessful ART treatments, five infertility treatment team members and 2 relatives of infertile couples were interviewed at an Infertility Center in Northeastern Iran from April 2016 to June 2017. Data were collected using semi-structured, face-to-face interviews. Data analysis was carried out following Sandelowski. Results: Iranian infertile couples’ experiences following failed ART cycles are described. The findings presented here show that Iranian infertile couples experience stressors during treatment cycles and systemic challenges which may be unique to the Iranian cultural context. Conclusions: Iranian infertile couples face particular challenges related to the cultural context in which ARTs are delivered. Further exploration of the effects of culture on the experiences of failed ARTs needs to be considered by infertility clinics in Ira

From HRI to CRI: Crowd Robot Interaction - understanding the effect of robots on crowd motion

How does the presence of a robot affect pedestri- ans and crowd dynamics, and does this influence vary across robot type? In this paper, we took the first step towards an- swering this question by performing a crowd-robot gate- crossing experiment. The study involved 28 participants and two distinct robot representatives: A smart wheelchair and a Pepper humanoid robot. Collected data includes: video recordings; robot and participant trajectories; and partici- pants’ responses to post-interaction questionnaires. Quanti- tative analysis on the trajectories suggests the robot affects crowd dynamics in terms of trajectory regularity and interac- tion complexity. Qualitative results indicate that pedestrians tend to be more conservative and follow “social rules” while passing a wheelchair compared to a humanoid robot. These insights can be used to design a social navigation strategy that allows more natural interaction by considering the robot effect on the crowd dynamics

Iranian infertile couples' strategies to manage social interactions after unsuccessful treatments with assisted reproductive technologies

Many infertile couples feel vulnerable after failed treatment cycles and find insensitive remarks or inappropriate support distressing. They fear that the stress of failed treatment cycles may affect their marriage and lead to marriage breakdown. This study explored the strategies a sample of infertile couples used to manage social interactions after unsuccessful treatment with assisted reproductive technologies. A descriptive qualitative study was conducted with 34 participants including nine infertile couples, nine infertile women and two infertile men with primary infertility, two relatives, and three fertility clinic staff. The participants were selected through purposive sampling at an infertility centre in Iran, between 2016 and 2017. Data were collected using semi-structured face-to-face interviews and analysed by qualitative content analysis approach. Participants found some social interactions after failed assisted reproductive treatment cycles to be distressing and painful. They described tolerating painful emotions which cause them sadness and sorrow as well as feeling embarrassed. As a result, they found they needed to maintain their adopting concealment strategies with their families through not permitting speculation, selective disclosure, not giving details and hiding the truth. This study showed that social interactions following failed assisted reproductive cycles can be upsetting for infertile couples. Couples use different strategies to manage potentially distressing social interactions. Healthcare providers and psychologists may provide a space for safe social interactions in order to help couples to use appropriate strategies in these circumstances

Infertile couples' perceived needs after unsuccessful fertility treatment: A qualitative study

Introduction: Infertility is a major medical issue. Investigations and treatment of infertility are the beginning of a complex, time-consuming and stressful process for couples that may fail well. The present study explored the needs of infertile couples following treatment failure with Assisted Reproductive Technologies (ARTs). Methods: A descriptive qualitative study was conducted in an Iranian infertility center, in the Northeast of the country between April 2016 and June 2017. The researchers recruited 29 individuals including 9 couples, 9 women and two men with primary infertility through purposive sampling. The data were collected using semi-structured interviews and analyzed iteratively, using conventional content analysis with MAXQDA software. Results: The main concepts obtained from the data were classified into one theme titled: ""The need for support"" and four main categories along with their subcategories, and included the need for psychological support, the need for more useful information, the need for social support and the need to access to supplementary services. Conclusion: The findings show that following treatment failure, the infertile patients’ expressed needs and preferences were not met. Identifying and meeting their needs may help the infertile couples to deal with ARTs failure and to reach a decision about future treatment

The significance of functional renal obstruction in predicting pathologic stage of upper tract urothelial carcinoma.

BACKGROUND AND PURPOSE: Assessing the severity of upper tract urothelial carcinoma (UTUC) has been difficult because of inadequate biopsy specimens. Additional predictive parameters of disease stage would be useful when deciding a treatment plan; it has been suggested that preoperative hydronephrosis can be a surrogate. We examined the relationship between preoperative ipsilateral renal obstruction identified by imaging with final pathologic stage after nephroureterectomy (NU) for UTUC. We then analyzed those patients with ipsilateral renal obstruction and examined if tumor location is associated with an advanced pathologic stage. METHODS: Patients who underwent NU for UTUC between the years 2001 to 2013 were analyzed and relevant staging studies and pathology were reviewed. Criteria for ipsilateral renal obstruction were defined by the presence of a delayed nephrogram on CT scan, renal cortical atrophy with associated hydronephrosis on cross-sectional imaging, and/or \u3e10% split function discrepancy on nuclear renal scintigraphy with associated hydronephrosis. RESULTS: Eighty-two patients met inclusion criteria; 26/82 (31.7%) had locally advanced disease (pT3/T4), while 56/82 (63.4%) had organ-confined (≤pT2) disease. Of the patients with pT3/T4 disease, 10/26 (38.5%) demonstrated radiographic evidence of functional obstruction of the ipsilateral renal unit; similarly, in patients with ≤pT2 disease, 21/56 (37.5%) demonstrated ipsilateral renal obstruction (P=0.93). Of the patients with ipsilateral renal obstruction, in those patients with pT3/T4 disease, 7/10 (70.0%) had ureteral tumor involvement while 9/21 (42.9%) patients with ≤pT2 disease had tumor in the ureter (P=0.25). CONCLUSIONS: This study suggests that renal obstruction by radiographic analysis does not always predict advanced stage. In addition, there is a trend toward advanced stage when a patient has radiographic evidence of ipsilateral renal dysfunction and a ureteral tumor

Hepatitis b vertical transfer and its risk factors in pregnant women in the eastern part of iran

One of the main causes of chronic hepatitis is mother to child transfer which is also known as vertical transfer (VT). Although there are several studies regarding the VT mechanism and its risk factors, none of these studies succeeded in explaining this process, completely. We conducted this study aiming at investigating VT mechanism and risk factors in this region. The present study was a descriptive-analytic cross-sectional study on HBS Ag positive pregnant women, which was conducted from March 2018 to March 2020 in Amir-AlMomenin Hospital in Zabol, Sistan-and-Baluchestan province, Iran. In this study all samples were tested for HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc, and HBV-DNA) and anti-HCV by enzyme-linked immunosorbent assay (ELISA). All statistical analyzes were performed using SPSS version 22 software. Totally 43 infants of HBS antigen positive mothers were investigated. HBe antibody and HBe antigen were found in 25 (62.5%) and 2 (5%) of mothers, respectively. There was no significant difference between the newborns with and without hepatitis B infection regarding maternal age (p=0.216), duration of the infection in mother (p=0.892), AST (0.779), AL (0.449) and ALP (0.065). Mothers with positive viral load during pregnancy delivered newborns with positive HBS antigen much more than mothers with negative HBS antigen. However, this difference was not statistically significant (p=0.642). Although positive viral load was more common in neonates delivered from positive viral load mothers, the observed difference was also remained non-significant (p=0.978). Our study provided evidences regarding that demographic, immunologic and clinical characteristics of mothers with hepatitis B infection did not play considerable role in the vertical transmission of the infection to the newborns as well as the severity of the following infection. We also suggested the possibility of placenta acting as a source of infection in VT. Further longitudinal studies with larger sample sizes are needed to show the exact predictors of transmission of the infection from infected mothers to their children, Amirian S., Afshari M., Parooie F., Keikhaie K.R., Shahramian I., Bazi A., Ostadrahimi P., Sheikh M., Mirzaie H., Aminisefat A.

Components of particulate matter air-pollution and brain tumors

Background Air pollution is an established carcinogen. Evidence for an association with brain tumors is, however, inconclusive. We investigated if individual particulate matter constituents were associated with brain tumor risk. Methods From comprehensive national registers, we identified all (n = 12 928) brain tumor cases, diagnosed in Denmark in the period 1989–2014, and selected 22 961 controls, matched on age, sex and year of birth. We established address histories and estimated 10-year mean residential outdoor concentrations of particulate matter ˂ 2.5 µm, primarily emitted black carbon (BC) and organic carbon (OC), and combined carbon (OC/BC), as well as secondary inorganic and organic PM air pollutants from a detailed dispersion model. We used conditional logistic regression to calculate odds ratios (OR) per inter quartile range (IQR) exposure. We adjusted for income, marital and employment status as well as area-level socio-demographic characteristics. Results Total tumors of the brain were associated with OC/BC (OR: 1.053, 95%CI: 1.005–1.103, per IQR). The data suggested strongest associations for malignant tumors with ORs per IQR for OC/BC, BC and OC of 1.063 (95% CI: 1.007–1.123), 1.036 (95% CI: 1.006–1.067) and 1.030 (95%CI: 0.979–1.085), respectively. The results did not indicate adverse effects of other PM components. Conclusions This large, population based study showed associations between primary emitted carbonaceous particles and risk for malignant brain tumors. As the first of its kind, this study needs replication.</p

Targeted Sequencing in Chromosome 17q Linkage Region Identifies Familial Glioma Candidates in the Gliogene Consortium

Glioma is a rare, but highly fatal, cancer that accounts for the majority of malignant primary brain tumors. Inherited predisposition to glioma has been consistently observed within non-syndromic families. Our previous studies, which involved non-parametric and parametric linkage analyses, both yielded significant linkage peaks on chromosome 17q. Here, we use data from next generation and Sanger sequencing to identify familial glioma candidate genes and variants on chromosome 17q for further investigation. We applied a filtering schema to narrow the original list of 4830 annotated variants down to 21 very rare (,0.1% frequency), non-synonymous variants. Our findings implicate the MYO19 and KIF18B genes and rare variants in SPAG9 and RUNDC1 as candidates worthy of further investigation. Burden testing and functional studies are planned
