RESUMO

PURPOSE: Low anterior resection syndrome (LARS) causes devastating symptoms and impairs the quality of life (QOL). This study investigated the incidence and risk factors of LARS and their association with the QOL in patients with lower rectal tumors. METHODS: Patients who underwent anus-preserving surgery for lower rectal tumors between 2014 and 2019 and who had anal defecation between 2020 and 2021 were surveyed. The LARS score measured severity, and the QOL was evaluated using the Japanese version of the Fecal Incontinence Quality-of-Life Scale (JFIQL). The primary endpoint was the incidence of Major LARS, and the secondary endpoints were risk factors and association with the JFIQL. RESULTS: Of 107 eligible patients, 82 (76.6%) completed the LARS survey. The incidence of Major LARS was 48%. Independent risk factors included neoadjuvant chemoradiotherapy (CRT) and a short interval (< 24 months after surgery; odds ratio, 4.6; 95% confidence interval: 1.1-19, both). The LARS score was moderately correlated with the JFIQL generic score (correlation coefficient: - 0.54). The JFIQL scores were significantly worse in the Minor and Major LARS groups than in the No LARS group. CONCLUSIONS: Major LARS was found in 48% of lower rectal tumors, and independent risk factors include neoadjuvant CRT and a short interval. The QOL was significantly impaired in patients with both Minor and Major LARS.

RESUMO

Aim: Low anterior resection syndrome (LARS) causes devastating symptoms and impairs quality of life (QOL). Although its incidence and risk factors have been reported, these data are scarce in Japan. This study aimed to elucidate the incidence and risk factors of LARS as well as to evaluate its association with QOL in Japanese patients. Method: Patients with anal defecation at the time of the survey between November 2020 and April 2021 were included, among those who underwent anus-preserving surgery for rectal tumors between 2014 and 2019 in tertiary referral university hospital. The severity of LARS and QOL were evaluated with the LARS score and the Japanese version of the fecal incontinence quality of life scale (JFIQL), respectively. Primary endpoint was the incidence of major LARS. Secondary endpoints were risk factors and association with JFIQL. Results: Of 332 eligible patients, 238 (71.7%) answered the LARS survey completely. The incidence of major LARS was 22% overall, and 48% when limited to lower tumors. Independent risk factors included lower tumors (OR: 7.0, 95% CI: 2.1-23.1, p = 0.001) and surgical procedures with lower anastomoses (OR: 4.6, 95% CI: 1.2-18.5, p = 0.03). The JFIQL generic score correlated moderately with the LARS score (correlation coefficient of -0.65). The JFIQL generic score was also significantly lower in lower tumors. Conclusions: The incidence of major LARS is 22% in Japanese patients, and independent risk factors include lower tumors and surgical procedures with lower anastomoses. More severe LARS is associated with worse QOL which is significantly more impaired in patients with lower tumors.

RESUMO

BACKGROUND: The aim of this study was to evaluate the effect of staple height and rectal wall thickness on the development of an anastomotic leak after laparoscopic low anterior resection performed with the double stapling technique. METHODS: One hundred ninety-nine patients treated from 2013 to 2021 were enrolled. Patients were divided into two groups: those who developed an anastomotic leak (AL (+)) and those who did not (AL (-)). Clinicopathological factors were compared between the groups. RESULTS: Anastomotic leaks were observed in 8/199 patients (4%). A 1.5 mm linear stapler was used for 35/199 patients (17%), 1.8 mm for 89 (45%), and 2 mm for 75 (38%). In the AL (+) group (n = 8), lower staple height (1.5 mm or 1.8 mm) was used more frequently than in the AL (-) group (n = 191). Rectal wall thickness and the rectal wall thickness to staple height ratio was significantly (p < .05) greater in the AL (+) group. However, rectal wall thickness was significantly (p < .05) greater in patients who received neoadjuvant treatment and those with advanced T stage (T3,4) lesions. CONCLUSION: Linear stapler staple height and rectal wall thickness are significantly associated with the development of an anastomotic leak after laparoscopic low anterior resection. Larger staples should be selected in patients with a thicker rectal wall due to neoadjuvant treatment or adjacent advanced rectal tumors.

RESUMO

Fecalomas most commonly occur in constipated patients and are rarely reported after colectomy. A 55-year-old Japanese female presented with a fecaloma after colectomy, which was impacted at a functional end-to-end anastomosis (FEEA) site. Four and a half years ago, she underwent sigmoidectomy for colon cancer. A follow-up computed tomography (CT) scan revealed an 11 cm incidental fecaloma. The patient was advised to undergo surgery, but she desired nonoperative management because of minimal symptoms, and was referred to our institution. On the day of admission (day 1), mechanical fragmentation of the fecaloma was attempted during the first colonoscopy. Although a large block of stool was evacuated after a second colonoscopic fragmentation on day 8, the third colonoscopy on day 21 and CT scan on day 22 showed no significant change in the fecaloma. Frequent colonoscopic fragmentation was performed, with a fourth, fifth, and sixth colonoscopy on days 24, 29, and 31, respectively. After the size reduction was confirmed at the sixth colonoscopy, the patient was discharged home on day 34. The fecaloma completely resolved after the seventh colonoscopic fragmentation on day 44. Sixteen months after treatment, there is no evidence of recurrent fecaloma. According to the literature, risk factors for fecaloma after colectomy include female gender, left-side colonic anastomosis, and FEEA. FEEA might not be recommended for anastomoses in the left colon, particularly in female patients, to avoid this complication. Colonoscopic fragmentation is recommended for fecalomas at an anastomotic site after colectomy in patients without an absolute indication for surgery.

RESUMO

BACKGROUND: Goblet cell carcinoid (GCC) is a neuroendocrine tumor usually found in the appendix. GCCs exhibit characteristic findings with mixed endocrine-exocrine features such as staining positive for neuroendocrine markers and producing mucin. The primary GCC of the rectum is exceedingly rare. CASE PRESENTATION: A 77-year-old Japanese male presented with hematochezia. Anal tenderness and a hard mass in the anal canal were found on the digital rectal examination, and colonoscopy was performed. Colonoscopy showed an irregularly shaped mass in the anal canal. Biopsy showed mixed features including adenocarcinoma in situ, well-differentiated adenocarcinoma, and mucinous carcinoma with invasive proliferation. No metastatic lesions were found on the computed tomography scan. Pelvic magnetic resonance imaging scan showed extramural growth of a tumor on the ventral side of the rectum without invasion to the prostate. Laparoscopic abdominoperineal resection was performed. The final diagnosis was well-differentiated adenocarcinoma in the mucosa and goblet cell carcinoid from the submucosa to the adventitia of the rectum. The patient was discharged from the hospital on postoperative day 16. Six months after resection, a computed tomography scan revealed multiple metastatic lesions in the liver. Several chemotherapy regimens were given, and the patient has stable disease 27 months after surgery. CONCLUSION: We present a patient with rectal GCC with metachronous liver metastases. Since GCC grows intramurally and is biologically aggressive compared to typical carcinoid lesions, the disease is usually diagnosed at an advanced stage. The development of optimal adjuvant chemotherapy is needed for those patients.

RESUMO

PURPOSE: This study explores the relationship between rural residency, selected protective factors (family and school connectedness along with prosocial peer attitudes), and health-compromising behaviors (alcohol and tobacco use and nonuse of seatbelt) among adolescents. METHODS: A subsample of adolescents residing in remote areas was extracted from a province-wide, school-based survey in British Columbia (BC), Canada (weighted N = 2,999). We employed χ2 statistic to test rural-urban differences separately by gender. Logistic regression analysis was used to examine the relationship between protective factors and behaviors compromising health. FINDINGS: In boys, rural residency was associated with multiple problem behaviors (binge drinking, smokeless tobacco use, and nonuse of seatbelt), whereas for girls it was linked to riding without a seatbelt. The final logistic regression models confirmed that rural environment was a significant risk factor for not wearing a seatbelt among both boys and girls, and smokeless tobacco among boys (adjusted odds ratio between 1.44 and 3.05). Rurality, on the other hand, did not predict binge drinking. Logistic regression analyses also revealed that both school connectedness and prosocial peer attitude protected boys against binge drinking and smokeless tobacco, but the results were not as robust for girls. CONCLUSIONS: These findings could provide information for location-based intervention efforts promoting adolescent health, highlighting the protective role of the school atmosphere and prosocial peer relationships, especially among boys.

RESUMO

PURPOSE: Sports participation and physical fitness are widely beneficial for young people, yet activity levels among young people are declining. Despite growing popular media attention on the participation of sexual minority (e.g., lesbian, gay, and bisexual) youth in sports and various campaigns to improve the often homophobic climate of sports, there is limited evidence that sexual minority youth participate in sports. Our aim was to provide a current portrait of sports participation among 3 groups of sexual minority youth (e.g., lesbian, gay, and bisexual) in British Columbia, Canada, as well as to document population trends. METHODS: Pooled population-level data from British Columbia, Canada (n = 99,373) were used to examine trends and disparities in sports participation among sexual minority and heterosexual youth. Age-adjusted logistic regression models were used to examine changes in participation over time and disparities in participation over time (1998-2013). RESULTS: We found an overall decline in sports participation and physical activity (PA) for all youth. Sexual minority students were less likely to participate in formal sports (with a coach) and informal sports (without a coach) compared with their heterosexual peers. The disparity in participating in informal sports between heterosexual and sexual minority youth has narrowed over time for some sexual orientation groups, whereas the disparity in participating in formal sports has widened over time in some cases. CONCLUSION: This study provides a comprehensive examination of sports participation among sexual minority youth over the past 15 years. Despite changing societal attitudes and laudable efforts to reduce homophobia in sports, results suggest that there are continued barriers to participation for sexual minority youth. Further research is needed to understand the factors that limit sports participation for these youth and to inform program development. PA is critical to lifelong health and well-being, and thus continued efforts are needed to increase the sports participation of sexual minority youth in particular.

RESUMO

OBJECTIVES: Despite evidence from numerous studies that document disparities in suicidality for sexual minorities, few have investigated whether or not these trends have improved over time, which is the objective of the current study. METHODS: Using school-based population data over a 15-year period (1998 to 2013), multivariate logistic regressions were used to calculate age-adjusted odds ratios separately by gender. Interactions were included to test widening or narrowing disparities within orientation groups, which makes this one of the first studies to test whether gaps in disparities between heterosexual and sexual minorities have widened or narrowed over time. RESULTS: Results show that sexual minority youth are persistently at a greater risk for suicidal behaviour, a trend that has continued particularly for bisexual youth of both sexes. Results also suggest that the gap in suicidal behaviour is widening among some female sexual orientation groups, yet narrowing for other male sexual orientation groups. CONCLUSIONS: These findings have important public health implications, especially since we see decreases in suicidal behaviour for heterosexual adolescents, but not in the same way for many sexual minority youth, despite advances in social acceptance of gay, lesbian, and bisexual issues in North America.

RESUMO

OBJECTIVE: Disordered eating has decreased for all youth over time, but studies have not focused specifically on lesbian, gay, and bisexual (LGB) youth. Research has found that LGB youth report disordered eating behaviors more often compared to their heterosexual counterparts, but no studies have documented trends over time for LGB youth and considered whether these disparities are narrowing or widening across sexual orientation groups. METHOD: We use pooled data from the 1999 to 2013 Massachusetts Youth Risk Behavior Surveys (N = 26,002) to investigate trends in purging, fasting, and using diet pills to lose or control weight for heterosexual and sexual minority youth. We used crosstabs, logistic regression, and interactions in regression models, stratified by sex. RESULTS: The prevalence of disordered eating has decreased on all three measures across nearly all groups of heterosexual and sexual minority youth. However, we found disparities in reported disordered eating behaviors for LGB youth persisted across all survey years, with LGB students reporting significantly higher prevalence of disordered eating than heterosexuals. The disparities in fasting to control weight widened between the first and last survey waves between lesbian adolescents and heterosexual females. DISCUSSION: The significant reductions over time in prevalence of disordered eating among some youth are encouraging, but the disparities remain. Indeed, the increasing prevalence of fasting, diet pill use, and purging to control weight among lesbians may warrant targeted prevention and intervention programs. © 2016 Wiley Periodicals, Inc.

RESUMO

BACKGROUND: Previous studies have documented higher health risks for lesbian, gay, and bisexual youth compared to heterosexual youth. However, none has reported whether the sexual orientation-based gaps have widened, narrowed, or remained unchanged over time. The purpose of this study was to develop a way to test differences in trends between sexual minority and heterosexual youth cohorts in population-based studies, with cigarette smoking as an exemplar. METHODS: We analysed the Minnesota Student Survey of 1998-2010, a repeated, cross-sectional census of adolescent health in grades 9 and 12. Our sample was students with recent sexual experience (Ns = 17,376-19,617). Sexual orientation was measured by gender of sexual partners in the past 12 months: students with only opposite-gender partner(s) (OPPOS), students with both male and female partners (BOTH), students with only same-gender partner(s) (SAME). We used logistic regressions to examine trends in prevalence of past-month cigarette smoking from 1998 to 2010, separately for each orientation group. We then applied novel interaction analyses to test whether disparities in smoking prevalence between OPPOS and SAME/BOTH changed over time. RESULTS: Recent smoking rates decreased over time among all orientation groups. BOTH adolescents were more likely than OPPOS adolescents to report past 30-day smoking, but there were no significant differences between SAME adolescents and OPPOS adolescents. Year-by-orientation interactions indicated the gap between BOTH adolescents and OPPOS adolescents widened from 1998 to 2004, then persisted between 2004 and 2010. No significant interaction effects were observed between SAME adolescents and OPPOS adolescents. CONCLUSIONS: All orientation groups had decreasing trends in recent cigarette smoking; however, disparities in smoking rates remain between heterosexual adolescents and bisexual adolescents. These results provide a new method of not just documenting trends within minority groups, but examining whether health equity is improving for them compared to dominant groups.

RESUMO

Numerous recent studies have demonstrated that schools are often unsafe for lesbian, gay, and bisexual (LGB) adolescents, who are more likely than heterosexual peers to be bullied, harassed, or victimized in school contexts. Virtually all of these studies call for change, yet none investigate whether or not it has occurred. Using repeated waves of a population-based high school survey, we examine (1) the extent to which sexual orientation differences in school bullying and violence-related experiences are reported by lesbian/gay, bisexual, and heterosexual male and female adolescents; (2) trends in school bullying and violence-related experiences for each gender/orientation group, and (3) whether disparities have changed over time. Data were drawn from eight Massachusetts biennial Youth Risk Behavior Surveys from 1999 to 2013, grouped into 4 waves totaling 24,845 self-identified heterosexual, 270 lesbian/gay, and 857 bisexual youth. Disparities between LGB and heterosexual peers were found in all indicators. Heterosexual youth and gay males saw significant reductions in every outcome between the first and last waves. Among bisexual males, skipping school due to feeling unsafe, carrying weapons in school, and being bullied all decreased, but among lesbians and bisexual females only fighting in school declined significantly. Improvement trends in school safety were more consistent for heterosexual youth and gay males than for bisexual or lesbian females. Notably, despite these improvements, almost no reduction was seen in sexual orientation disparities. Future research should identify influences leading to reduced school victimization, especially focusing on ways of eliminating persistent sexual orientation disparities. Future research should identify influences leading to reduced school victimization, especially focusing on ways of eliminating persistent sexual orientation disparities.

RESUMO

Despite the large number of East Asian youth in Canada, little is known about their health and risk behaviors. We examined the relationship between ethnic identity and sexual initiation among East Asians. This secondary analysis of a population-based survey selected 4,311 students in 7-12th grades who described themselves as East Asian (e.g., Chinese, Japanese, Korean). Gender-stratified logistic regression analyses examined whether ethnic identity was associated with sexual initiation, controlling for age, living situation, and cultural exposure. Boys with stronger commitment to their ethnic groups were less likely to have ever had sexual intercourse (aOR 0.80). Girls with higher levels of ethnic identity exploration were less likely to report sexual initiation (aOR 0.71). Stronger ethnic identity was associated with not having sexual intercourse among East Asian adolescents. The findings suggest the need to consider ethnocultural factors in future research and practice.

RESUMO

Enacted stigma has been linked to increased HIV risk behaviours among sexual minority youth, but despite higher rates of HIV and other STIs, there is very little research with Indigenous youth. In this study, secondary analyses of three population-based, school surveys were conducted to explore the associations between HIV risk and enacted stigma among sexual minority Indigenous youth in Canada, the US, and New Zealand. Data were analyzed and interpreted with guidance from Indigenous and sexual minority research team members, Indigenous advisory groups, and community consultations. In all three countries, Indigenous sexual minority youth were more likely to experience enacted stigma (such as bullying, discrimination, exclusion, harassment, or school-based violence) and report increased HIV risk behaviours (such as lack of condom use, multiple sexual partners, pregnancy involvement, and injection drug use) compared to heterosexual peers. Data were analyzed by age, gender, and sexual orientation, and for some groups, higher levels of enacted stigma was associated with higher HIV risk. The findings highlight the need for more research, including identifying protective factors, and developing interventions that focus on promoting resilience, addressing the levels of stigma and homophobic violence in school, and restoring historical traditions of positive status for Indigenous sexual minority people.

RESUMO

This study explored the relationships between the existence of and length of time since implementation of school-based Gay-Straight Alliances (GSAs) and explicit anti-homophobic bullying policies in secondary schools across British Columbia, Canada, with experiences of anti-gay discrimination, suicidal ideation and attempts among lesbian, gay, bisexual (LGB), mostly heterosexual, and exclusively heterosexual students. Analyses of the province-wide random cluster-stratified 2008 B.C. Adolescent Health Survey (n =21,70 8) compared students in schools with GSAs or policies implemented at least 3 years, and less than 3 years, with those in schools without GSAs or anti-homophobia policies, using multinomial logistic regression, separately by gender. LGB students had lower odds of past year discrimination, suicidal thoughts and attempts, mostly when policies and GSAs had been in place for 3+ years; policies had a less consistent effect than GSAs. Heterosexual boys, but not girls, also had lower odds of suicidal ideation and attempts in schools with longer-established anti-homophobic bullying policies and GSAs. Given consistently higher documented risk for suicidal ideation and attempts among LGB and mostly heterosexual adolescents, prevention efforts should be a priority, and school-level interventions, such as GSAs, may be an effective approach to reducing this risk, while also offering prevention benefits for heterosexual boys.

RESUMO

We examined the psychometric properties of scores on a 6-item version of the Multigroup Ethnic Identity Measure (MEIM) among East Asian adolescents in Canada. A series of confirmatory factor analysis (CFA) was conducted for 4,190 East Asians who completed a provincial survey of students in grades 7 to 12. The MEIM measured highly correlated dimensions of ethnic identity (exploration and commitment). Further, multi-group CFA indicated that the scale measured the same constructs on the same metric across three age groups and across four groups with varying degrees of exposure to Canadian and East Asian cultures. The findings suggest the short version of the MEIM can be used to compare levels of ethnic identity across different age or acculturation groups.

RESUMO

OBJECTIVE: This study examined whether students' odds of recent substance use were lower in the presence of gay-straight alliances or explicit anti-homophobia policy that had been established at their school recently, or at least 3 years prior. METHODS: We analyzed a population-based sample of students in grades 8 through 12 from the British Columbia Adolescent Health Survey of 2008 (weighted N=21,708). We used multi-nomial logistic regressions to test the hypothesized effects of gay-straight alliances and policies on substance use outcomes for lesbian, gay and bisexual students, and heterosexual students separately. RESULTS: Results indicated that gay-straight alliances and anti-homophobic bullying policies were linked to significantly lower odds of some but not all types of recent risky alcohol use, and past-year harms from alcohol or drug use, but almost exclusively in schools where the policies or gay-straight alliances had been established for at least 3 years; and among lesbian, gay and bisexual adolescents, only for girls. CONCLUSIONS: Our findings suggest that these school-based strategies (gay-straight alliances and anti-homophobia policies) to reduce homophobia and foster school inclusion may be beneficial in reducing problem alcohol use among all students, not just sexual minority students.

RESUMO

Despite the large number of adolescents of East Asian origin in Canada, there is limited research on sexual health among this population. A first step to develop strategies for sexual health promotion for adolescents is to document the prevalence of sexual behaviours. This study thus estimated the prevalence of sexual health and risk behaviours among East Asian adolescents in grades 7 to 12, using the province-wide, school-based 2008 British Columbia Adolescent Health Survey (unweighted N = 4,311). Less than 10% of East Asian adolescents have ever had sexual intercourse. However, most of these sexually active adolescents have engaged in risky sexual behaviours, including multiple sexual partners and non-condom use at last intercourse. In particular, nearly half of sexually active girls reported not using a condom at last intercourse. Compared to immigrant students whose primary language at home was not English, immigrant and Canadian-born students speaking English at home were more likely to experience sexual intercourse. Among students who have never had sexual intercourse, two most common reasons for sexual abstinence were not feeling ready and waiting to meet the right person. Findings suggest the need for sexual health interventions tailored to gender and sociocultural contexts in which adolescents live.

RESUMO

PURPOSE: Childhood and adolescent sexual abuse has been shown to lead to increased odds of sexual behaviors that lead to sexually transmitted infections and early pregnancy involvement. Research, meta-analyses, and interventions, however, have focused primarily on girls and young women who have experienced abuse, yet some adolescent boys are also sexually abused. We performed a meta-analysis of the existing studies to assess the magnitudes of the link between a history of sexual abuse and each of the three risky sexual behaviors among adolescent boys in North America. METHODS: The three outcomes were (a) unprotected sexual intercourse, (b) multiple sexual partners, and (c) pregnancy involvement. Weighted mean effect sizes were computed from ten independent samples, from nine studies published between 1990 and 2011. RESULTS: Sexually abused boys were significantly more likely than nonabused boys to report all three risky sexual behaviors. Weighted mean odds ratios were 1.91 for unprotected intercourse, 2.91 for multiple sexual partners, and 4.81 for pregnancy involvement. CONCLUSIONS: Our results indicate that childhood and adolescent sexual abuse can substantially influence sexual behavior in adolescence among male survivors. To improve sexual health for all adolescents, even young men, we should strengthen sexual abuse prevention initiatives, raise awareness about male sexual abuse survivors' existence and sexual health issues, improve sexual health promotion for abused young men, and screen all people, regardless of gender, for a history of sexual abuse.

RESUMO

The purpose of this study was to examine the relationship between substance use and sexual orientation among Asian adolescents in Canada. We analyzed an East and Southeast Asian subsample of a province-wide, school-based survey (weighted N = 51,349). Compared to heterosexual adolescents of the same gender, gay, lesbian, bisexual, and mostly heterosexual adolescents were more likely to use alcohol, marijuana, or other illicit drugs. Particularly, sexual minority girls were at increased risk for substance use. The findings suggest the need for substance use prevention interventions that are sensitive to gender, sexual orientation, and culture.

RESUMO

The exchange of sexual activities for money, drugs, or other compensation is considered a form of sexual exploitation when it occurs among underage youth. Such practices have been associated with sexual behaviours that increase the risk of sexually transmitted infections. Much of the research on this issue has been conducted on homeless or street-involved youth while adolescents in regular schools have received less attention in this area. The present study examined the prevalence of and factors associated with the exchange of sex for drugs among substance-using students in rural western Canada. Our data source was the 2009 East Kootenay Adolescent Drug Use Survey, a census of students in grades 7-12, who had ever used alcohol, marijuana, or other illicit drugs. In the sample of 2,360 youth, 2% of boys and 3% of girls reported that they had ever exchanged sex for alcohol or drugs, i.e., "exploited" youth, the majority of whom (83% - 98%) were living with family members. The most frequent patterns of past-year substance use were "using alcohol only" for "non-exploited" youth, and using alcohol, marijuana, and other drugs for exploited youth. The exchange of sex was associated with the use of drugs other than alcohol in the past year and with a higher level of impulsivity. The odds of exchanging sex were lower among youth who reported positive family relationships. The findings suggest a need for in-school education about healthy relationships, sexual exploitation, substance use, and impulse control.
