Purpose: To identify trends in female authorship in the Canadian Association of Radiologists Journal (CARJ) from 2010 to 2019. Methods: We retrieved papers published in the CARJ over a 10-year period, and retrospectively reviewed 602 articles. All articles except editorials and advertisements were included. We categorized the names of the first and last position authors as female or male and excluded articles that had at least one author of which gender was not known. We compared the trends in the first and last position authors of the articles from 2010 to 2019. For statistical analysis, logistic regression was performed with reported odds ratios (ORs), and a P value of <.05 was defined as statistically significant. Results: Five hundred thirteen articles met inclusion criteria. Among them, 23 articles with a single author were classified as having only a first author. 39.8% (204/513) of first authors were female and 26.9% (132/490) of last authors were female. There has been an overall temporal increase in the odds of both the first and last author being female in CARJ publications (OR: 1.11, P = .034). Similarly, the odds a CARJ publication’s first author being female increased over time (OR: 1.07, P = .033). Female last author did not predict female first author (OR: 1.48, P = .056). There was no association identified between female last author and year of publication (OR: 1.04, P = .225). Conclusion: There has been an overall increase in engagement of female authorship in CARJ.

Abstract BACKGROUND: Anemia remains the most common hematologic disorder in human immunodeficiency virus (HIV) infection despite the use of effective antiretroviral therapy, and is associated with decreased quality of life and survival. Hypogonadism is prevalent in advanced HIV disease, however low testosterone levels have not been customarily implicated in HIV-associated anemia. This study was undertaken to determine whether there is a relationship between testosterone levels and androgen use with anemia in HIV, and to characterize other clinical correlates of HIV-associated anemia. METHODS: This cross-sectional study examined the clinical characteristics of 200 HIV positive patients at a public hospital HIV clinic and clinical features associated with anemia. A written questionnaire detailed previous and current medication use, opportunistic infections and malignancies. Hematologic and virologic parameters, testosterone and erythropoietin levels were measured; CD4 count and viral load nadir and peak levels were obtained from the computerized medical record. Anemia was defined as hemoglobin <13.5 g/dL in men and <11.6 g/dL in women. RESULTS: Anemia was present in 24% of women and 28% of men. Anemia was negatively associated with female sex (adjusted OR 0.30, 95% CI 0.11–0.85), current antiretroviral therapy (adjusted OR 0.43, 95% CI 0.20–0.95), current androgen use (adjusted OR 0.20, 95% CI 0.05–0.84) and macrocytosis (adjusted OR 0.23, 95% CI 0.09–0.61). Anemia was positively associated with lymphopenia (adjusted OR 4.0, 95% CI 1.36–11.80), high erythropoieitin levels (adjusted OR 7.73, 95% CI 2.92–20.48) and low testosterone levels (adjusted OR 3.27, 95% CI 1.01–10.60). CONCLUSIONS: Low testosterone levels may have a positive association, and supplemental androgens a negative association with anemia in HIV disease. Predictors of Anemia Unadjusted odds ratios and 95% confidence intervals obtained by logistic regression. Variables that achieved a p-value of <0.1 in tests of interaction were included in a multivariable logistic regression model, which was used to obtain adjusted odds ratios and 95% confidence intervals.

Purpose: More adolescents “vape” (use e-cigarettes and similar devices) than smoke, but little is known about how underage users obtain vaping devices. This knowledge could inform efforts to prevent youth access. Design: Original cross-sectional survey with social media recruitment. Settings: Online. Participants: A total of 1729 adolescents (2809 qualified on screener; completion rate 61.6%) aged 15 to 17 years who vaped in the past 30 days. Measures: Adolescents’ vaping attitudes, ownership of vaping devices, how they obtain devices, and frequency of borrowing others’ devices. Analysis: Logistic regression. Results: Most adolescents (78.2%) owned a vaping device. The most common sources were purchasing from a store or online (31.1%), buying from another person (16.3%), or giving someone money to purchase for them (15.0%). The majority (72.8%) had used someone else’s vaping device in the past 30 days. Adolescents who vaped more often, did not own a vaping device, vaped in social situations, and had previously been refused purchase were more likely to frequently borrow others’ devices. Conclusions: Despite high rates of ownership, many adolescents borrowed devices, suggesting that borrowing is part of users’ social experience, not just a means of acquisition. Although better enforcement of age restrictions could lessen purchasing, future research is needed to understand why adolescents borrow and how their acquisition sources shift over time. That information could be harnessed for targeted, borrowing-related antivaping campaigns.

AbstractA statistical analysis is presented that investigates the dependence of team cities’ geographical distances on the effect of home advantage (HA) for 57 years of the men’s German first soccer division (“Bundesliga”), including 17,376 matches (seasons starting from 1964 to 2020). The data shows that the HA can clearly be evidenced in the past and present (statistical p‑value < 0.01) and that it also exists for negligible distances (p < 0.01). The HA and the influence of distance on the HA both significantly decreased gradually over the last decades (p < 0.01). For the first and only time, the HA reversed into an away advantage (AA) for the season 2019/2020 (p < 0.01). The influence of distance on HA has been significant (p < 0.01) in the past (before about 1990) and contributed roughly by about half, compared to a situation without HA or AA. It increases with distance and saturates at around 100 km. Such saturation behaviour is in line with results from higher divisions of other countries with similar travelling distances such as Italy, Turkey and England. However, the distance-dependent contribution to HA has been approximately halved and reduced to an insignificant amount today. Furthermore, the temporal HA reduction is significantly larger for large distances compared to short distances (p < 0.01). Reporting and quantifying a reduction (p < 0.01) of the distance-dependent contribution to HA over a time span of 57 years is novel.

A total of 1 558 080 lactation records from PATLQ Holstein cows were used to describe the annual trends in reasons for disposal in Quebec dairy herds from 1981 to 1994. Differences in culling trends between official and owner sampler herds, between parities, and between Quebec agricultural regions were compared. Statistical analysis was carried out by means of a logistic regression model, and the significance of trends was tested by linear contrasts. Involuntary culling had a clearly ascending trend during the period of study (from 23% in 1981 to 32% in 1994), as opposed to culling for low production (voluntary), which had a descending trend (from 16% in 1981 to 4.5% in 1994). This increase in involuntary culling was mainly due to increasing trends in culling for reproductive problems, mastitis and feet and leg problems. Official herds had a greater proportion of cows with sale codes and fewer cows culled for mastitis than owner sampler herds, and the trend for sale codes was ascending for official and stable for owner sampler herds. Culling for low production was more intensive in first parity, but all parities showed a descending trend over time. The proportion of cows with sale codes decreased with parity number. For all involuntary reasons, proportion of cows culled increased with parity number. Key words: Reasons for disposal, Holstein, Quebec, culling

ABSTRACT. Hyperbilirubinemia refers to an excessive level of accumulated bilirubin in the blood and ischaracterized by jaundice, or icterus, a yellowish discoloration of the skin and other organs. There are two riskfactors that related to hyperbilirubinemia. Those factors are maternal factor and neonates‟ factor. The aim ofthis research knew which variables which catagorized as maternal factor and neonates‟ factor that related tohyperbilirubinemia in Persahabatan hospital. This research used medical records from 216 neonates andhis/her mother from October 2008 until October 2009 as samples. Research design was case control, with used5% level of significant and 80% power. The statistical analysis was multivariable logistic regression. Factorsthat related to hyperbilirubinemia in Persahabatan hospital were type of labor (p value 0.000) andprematurity (p value 0.022). Type of labor is a dominant variable that related to hyperbilirubinemia andneonates from un-spontaneous labor has probability to be hyperbilirubinemia 50.193 times than neonates fromspontaneous labor after controlled by prematurity (odds ratio 50.193).Keywords: hyperbilirubinemia, type of labor, prematurity

The objective of this study was to describe the epidemiology of canine urolithiasis in Hungary in order to determine the annual incidence of urolithiasis and to identify breeds at risk for different types of urolithiasis. Data of a total of 2,543 canine uroliths analysed in the laboratory of the Budapest Urolith Centre were evaluated retrospectively from 2001 to 2012. Logistic regression was used to assess odds ratios for the proportion of each affected breed compared to those of crossbreeds. The annual incidence of urolithiasis was evaluated by the number of submissions compared to the estimated number of dogs in the population from which the samples originated. Epidemiologic data revealed a relatively high and increasing proportion of struvite urolithiasis. Statistical analysis of breed predispositions resulted in the detection of breeds not having been reported at risk (e.g. Bernese Mountain dog — struvite, Bichon Frise, Bolognese, Tibetan Terrier — purine, French Bulldog — cystine). Conflicting results were revealed for some other breeds previously described as being affected by certain types of urolithiasis (Chihuahua, Pekingese, Shih Tzu, English Cocker Spaniel). Regardless of the type of urolithiasis, its average cumulative incidence in the dog population of Hungary was found to be 1.76/10,000/year.

AbstractDizygotic twinning rates have changed over time, which has been seen as a sign of a decline in fecundity. Since a woman's birthweight has been shown to be a marker of her fecundity, maternal birthweight may correlate with subsequent twinning rates. In the Danish National Birth Cohort (1996–2002), we examined if maternal birthweight, and whether she was born at term or preterm, correlated with her probability of multiple birth. For 20,719 live born infants, we had self-reported information about maternal birthweight, collected during the first wave of the 7-year follow-up, and information on multiple births from record linkage. The association between maternal birthweight and multiple births was investigated by use of logistic regression and presented as odds ratios (ORs) with 95% confidence intervals (CIs). Compared to women born at term with a birthweight of 3001–4000 g, women with a birthweight > 4500 g appeared to have higher chance of multiple birth while women with a birthweight of 4001–4500 had a lower chance, especially if the analysis was restricted to women with a BMI < 25 (Adjusted ORs 2.3 [1.0–5.4] and 0.4 [0.2–0.9] respectively). Odds ratios for dizygotic twinning were of the same magnitude. In women with a BMI ≥ 25, no obvious pattern was present. Our findings do not indicate that twinning is a fecundity indicator. Women with a birthweight that may indicate a pregnancy complicated with gestational diabetes had the highest rate of multiple birth. These findings are new and should be put to a critical test in other data sources.

The aim of this study is to find the association between Intimate Partner Violence (IPV) and contraceptive use among married women in Pakistan. The analysis was conducted by using cross sectional secondary data from every married women of reproductive age 15-49 years who responded to domestic violence module (N = 3687) of the 2012-13 Pakistan Demographic and Health Survey. The association between contraceptive use (outcome variable) and IPV was measured by calculating unadjusted odds ratios and adjusted odds ratios with 95% confidence intervals using simple binary logistic regression and multivariable binary logistic regression. The result showed that out of 3687 women, majority of women 2126 (57.7%) were using contraceptive in their marital relationship. Among total, 1154 (31.3%) women experienced emotional IPV, 1045 (28.3%) women experienced physical IPV and 1402 (38%) women experienced both physical and emotional IPV together respectively. All types of IPV was significantly associated with contraceptive use and women who reported emotional IPV (AOR 1.44; 95% CI 1.23, 1.67), physical IPV (AOR 1.41; 95% CI 1.20, 1.65) and both emotional and physical IPV together (AOR 1.49; 95% CI 1.24, 1.72) were more likely to use contraceptives respectively. The study revealed that women who were living in violent relationship were more likely to use contraceptive in Pakistan. Still there is a need for women reproductive health services and government should take initiatives to promote family planning services, awareness and access to contraceptive method options for women to reduce unintended or mistimed pregnancies that occurred in violent relationships.

The Impact

Objective: While the use of intraoperative laser angiography (SPY) is increasing in mastectomy patients, its impact in the operating room to change the type of reconstruction performed has not been well described. The purpose of this study is to investigate whether SPY angiography influences post-mastectomy reconstruction decisions and outcomes. Methods and materials: A retrospective analysis of mastectomy patients with reconstruction at a single institution was performed from 2015-2017.All patients underwent intraoperative SPY after mastectomy but prior to reconstruction. SPY results were defined as ‘good’, ‘questionable’, ‘bad’, or ‘had skin excised’. Complications within 60 days of surgery were compared between those whose SPY results did not change the type of reconstruction done versus those who did. Preoperative and intraoperative variables were entered into multivariable logistic regression models if significant at the univariate level. A p-value <0.05 was considered significant. Results: 267 mastectomies were identified, 42 underwent a change in the type of planned reconstruction due to intraoperative SPY results. Of the 42 breasts that underwent a change in reconstruction, 6 had a ‘good’ SPY result, 10 ‘questionable’, 25 ‘bad’, and 2 ‘had areas excised’ (p<0.01). After multivariable analysis, predictors of skin necrosis included patients with ‘questionable’ SPY results (p<0.01, OR: 8.1, 95%CI: 2.06 – 32.2) and smokers (p<0.01, OR:5.7, 95%CI: 1.5 – 21.2). Predictors of any complication included a change in reconstruction (p<0.05, OR:4.5, 95%CI: 1.4-14.9) and ‘questionable’ SPY result (p<0.01, OR: 4.4, 95%CI: 1.6-14.9). Conclusion: SPY angiography results strongly influence intraoperative surgical decisions regarding the type of reconstruction performed. Patients most at risk for flap necrosis and complication post-mastectomy are those with questionable SPY results.

Gerd Symptoms

Background: The prevalence of gastroesophageal reflux disease (GERD) is increasing worldwide and the related chronic symptoms can be associated with morbidity and poor quality of life. Objective: The objective of this study was to identify foods and beverages consumed by the Lebanese population, dietary habits, socio-demographic and lifestyle factors, health parameters and perceived stress, implicated in increasing GERD symptoms. Methods: This observational cross-sectional study was carried among Lebanese adults in 2016. A convenient sample of 264 participants was equally divided into a GERD group and a control group. Data on socio-demographic characteristics, lifestyle, health status and dietary habits including Lebanese traditional dishes were collected. The perceived stress scale (PSS) was also used to assess the participants’ perception of stress. Logistic regression analyses were conducted with GERD symptoms (presence or absence) being the dependent variable. Results: The GERD symptoms were significantly associated with age (-p-value=0.017), family history of GERD symptoms (-p-value<0.001), smoking (-p-value=0.003) and chronic medical conditions (-p-value<.001). Regarding the dietary factors, participants who ate three meals or less/day, between meals and outside homes were 2.5, 2.9 and 2.4 times at a higher risk of experiencing GERD symptoms than others, respectively. Moreover, the logistic regression model showed that the GERD symptoms were significantly associated with the consumption of coffee (-p-value=0.037), Lebanese sweets (-p-value=0.027), fried foods (-p-value=0.031), ‘Labneh’ with garlic (-p-value<0.001), pomegranate molasses (-p-value=0.011), and tomatoes (-p-value=0.007). Conclusion: Some specific lifestyle factors and components of the Lebanese Mediterranean diet could be associated with GERD symptoms.
