Incidence of Induced Abortion in Uganda, 2013: New Estimates Since 2003

BackgroundIn Uganda, abortion is permitted only when the life of a woman is in danger. This restriction compels the perpetuation of the practice in secrecy and often under unsafe conditions. In 2003, 294,000 induced abortions were estimated to occur each year in Uganda. Since then, no other research on abortion incidence has been conducted in the country.MethodsData from 418 health facilities were used to estimate the number and rate of induced abortion in 2013. An indirect estimation methodology was used to calculate the annual incidence of induced abortions ─ nationally and by major regions. The use of a comparable methodology in an earlier study permits assessment of trends between 2003 and 2013.ResultsIn 2013, an estimated 128,682 women were treated for abortion complications and an estimated 314,304 induced abortions occurred, both slightly up from 110,000 and 294,000 in 2003, respectively. The national abortion rate was 39 abortions per 1,000 women aged 15–49, down from 51 in 2003. Regional variation in abortion rates is very large, from as high as an estimated 77 per 1,000 women 15–49 in Kampala region, to as low as 18 per 1,000 women in Western region. The overall pregnancy rate also declined from 326 to 288; however the proportion of pregnancies that were unintended increased slightly, from 49% to 52%.ConclusionUnsafe abortion remains a major problem confronting Ugandan women. Although the overall pregnancy rate and the abortion rate declined in the past decade, the majority of pregnancies to Ugandan women are still unintended. These findings reflect the increase in the use of modern contraception but also suggest that a large proportion of women are still having difficulty practicing contraception effectively. Improved access to contraceptive services and abortion-related care are still needed.     

Estimating Leptospirosis Incidence Using Hospital-Based Surveillance and a Population-Based Health Care Utilization Survey in Tanzania

Background

The incidence of leptospirosis, a neglected zoonotic disease, is uncertain in Tanzania and much of sub-Saharan Africa, resulting in scarce data on which to prioritize resources for public health interventions and disease control. In this study, we estimate the incidence of leptospirosis in two districts in the Kilimanjaro Region of Tanzania.

Methodology/Principal Findings

We conducted a population-based household health care utilization survey in two districts in the Kilimanjaro Region of Tanzania and identified leptospirosis cases at two hospital-based fever sentinel surveillance sites in the Kilimanjaro Region. We used multipliers derived from the health care utilization survey and case numbers from hospital-based surveillance to calculate the incidence of leptospirosis. A total of 810 households were enrolled in the health care utilization survey and multipliers were derived based on responses to questions about health care seeking in the event of febrile illness. Of patients enrolled in fever surveillance over a 1 year period and residing in the 2 districts, 42 (7.14%) of 588 met the case definition for confirmed or probable leptospirosis. After applying multipliers to account for hospital selection, test sensitivity, and study enrollment, we estimated the overall incidence of leptospirosis ranges from 75–102 cases per 100,000 persons annually.

Conclusions/Significance

We calculated a high incidence of leptospirosis in two districts in the Kilimanjaro Region of Tanzania, where leptospirosis incidence was previously unknown. Multiplier methods, such as used in this study, may be a feasible method of improving availability of incidence estimates for neglected diseases, such as leptospirosis, in resource constrained settings.

人工流产及流产后关爱服务的现状分析

人工流产后关爱服务(PAC)是一项标准化的服务流程,是对流产后的女性进行的关爱服务,其目的是有效降低重复流产率、保护女性的生殖健康、提升女性的生活质量。目前在我国流产后关爱服务还未完全落到实处,因此需要在各个医院和社区开展的相关活动,推进APC服务的发展。     

Allomaternal Care among the Hadza of Tanzania

Cooperative child care among humans, where individuals other than the biological mother (allomothers) provide care, may increase a mother’s fertility and the survivorship of her children. Although the potential benefits to the mother are clear, the motivations for allomothers to provide care are less clear. Here, we evaluate the kin selection allomothering hypothesis using observations on Hadza hunter-gatherers collected in ten camps over 17 months. Our results indicate that related allomothers spend the largest percentage of time holding children. The higher the degree of relatedness among kin, the more time they spend holding, supporting the hypothesis of nepotism as the strongest motivation for providing allomaternal care. Unrelated helpers of all ages also provide a substantial amount of investment, which may be motivated by learning to mother, reciprocity, or coercion.

Barriers to Rural Induced Abortion Services in Canada: Findings of the British Columbia Abortion Providers Survey (BCAPS)

Background

Rural induced abortion service has declined in Canada. Factors influencing abortion provision by rural physicians are unknown. This study assessed distribution, practice, and experiences among rural compared to urban abortion providers in the Canadian province of British Columbia (BC).

Methods

We used mixed methods to assess physicians on the BC registry of abortion providers. In 2011 we distributed a previously-published questionnaire and conducted semi-structured interviews.

Results

Surveys were returned by 39/46 (85%) of BC abortion providers. Half were family physicians, within both rural and urban cohorts. One-quarter (17/67) of rural hospitals offer abortion service. Medical abortions comprised 14.7% of total reported abortions. The three largest urban areas reported 90% of all abortions, although only 57% of reproductive age women reside in the associated health authority regions. Each rural physician provided on average 76 (SD 52) abortions annually, including 35 (SD 30) medical abortions. Rural physicians provided surgical abortions in operating rooms, often using general anaesthesia, while urban physicians provided the same services primarily in ambulatory settings using local anaesthesia. Rural providers reported health system barriers, particularly relating to operating room logistics. Urban providers reported occasional anonymous harassment and violence.

Conclusions

Medical abortions represented 15% of all BC abortions, a larger proportion than previously reported (under 4%) for Canada. Rural physicians describe addressable barriers to service provision that may explain the declining accessibility of rural abortion services. Moving rural surgical abortions out of operating rooms and into local ambulatory care settings has the potential to improve care and costs, while reducing logistical challenges facing rural physicians.     

不同人群人工流产术围手术期预防用多西环素临床分析

目的:分析不同人群人工流产术围手术期预防用多西环素的临床疗效。方法:采用回顾性调查方法,抽取本院2012年要求行人工流产术的日间手术住院患者4073例,分为正常人群和高危人群。正常人群中预防用多西环素者(预防组)2007例,未预防用抗菌药物组(未预防组)688例,高危人群中预防组865例,未预防组513例。对比分析不同人群预防组和未预防组术后1个月的手术部位感染率和远期(1年)并发症发生率。结果:正常人群预防组的手术部位感染率及远期并发症发生率分别为2.14%、7.77%,均分别显著低于未预防组的6.54%、11.05%(P0.05),而高危人群预防组分别为4.62%、10.06%,与未预防组的4.68%、12.09%比较,差异均无统计学意义(P0.05)。结论:围手术期预防用多西环素可降低人工流产术中正常人群的手术部位感染率和远期并发症发生率,而对于高危人群的作用不明显,因此术前应对患者的高危感染因素进行积极治愈或纠正后,预防用药价值可能较大。     

Area Differences in Spontaneous Abortion Rates in South Wales and Their Relation to Neural Tube Defect Incidence

Data are presented from the South Wales Congenital Malformation Survey (92,982 births 1964-6 inclusive) showing that within areas in South Wales there exists an inverse relation between previous spontaneous abortion rate and the prevalence at birth of neural tube defect (anencephaly or spina bifida cystica or both). This relation is independent of social class, parity, and maternal age, and is not likely to be explained by area differences in accuracy of reporting previous spontaneous abortions.On the basis of these findings a hypothesis is advanced which proposes that the incidence of neural tube defects is uniform throughout South Wales and that the present substantial and relatively stable differences in area prevalence are controlled by small area differences in mortality of malformed embryos. This would seem to suggest that factors initiating the malformation are genetic and that any related environmental factors exert their effect on already abnormal fetuses by influencing, in one way or another, their capacity to survive.     

Multi-Level Factors Affecting Entry into and Engagement in the HIV Continuum of Care in Iringa,Tanzania

Progression through the HIV continuum of care, from HIV testing to lifelong retention in antiretroviral therapy (ART) care and treatment programs, is critical to the success of HIV treatment and prevention efforts. However, significant losses occur at each stage of the continuum and little is known about contextual factors contributing to disengagement at these stages. This study sought to explore multi-level barriers and facilitators influencing entry into and engagement in the continuum of care in Iringa, Tanzania. We used a mixed-methods study design including facility-based assessments and interviews with providers and clients of HIV testing and treatment services; interviews, focus group discussions and observations with community-based providers and clients of HIV care and support services; and longitudinal interviews with men and women living with HIV to understand their trajectories in care. Data were analyzed using narrative analysis to identify key themes across levels and stages in the continuum of care. Participants identified multiple compounding barriers to progression through the continuum of care at the individual, facility, community and structural levels. Key barriers included the reluctance to engage in HIV services while healthy, rigid clinic policies, disrespectful treatment from service providers, stock-outs of supplies, stigma and discrimination, alternate healing systems, distance to health facilities and poverty. Social support from family, friends or support groups, home-based care providers, income generating opportunities and community mobilization activities facilitated engagement throughout the HIV continuum. Findings highlight the complex, multi-dimensional dynamics that individuals experience throughout the continuum of care and underscore the importance of a holistic and multi-level perspective to understand this process. Addressing barriers at each level is important to promoting increased engagement throughout the continuum.     

Lifetime Induced Abortion: A Comparison between Women Living and Not Living with HIV

Background

Studies aimed at understanding the association between induced abortion and HIV are scarce and differ on the direction of the association. This paper aims to show the prevalence of induced abortion in a sample of pregnancies of women living and not living with HIV/Aids, determining variables associated with pregnancy termination and linked to the life course of women and to the specific context of the pregnancy.

Methods

Data came from a cross-sectional study, using interviewer-administered questionnaire, developed with women that attended public health services in Porto Alegre, Brazil. A generalized estimating equation model with logit link measured the association between determinants and abortion.

Findings

The final sample was composed of 684 women living with HIV/Aids (2,039 pregnancies) and 639 women not living with HIV/Aids (1,539 pregnancies). The prevalence of induced abortion among pregnancies in women living with HIV/Aids was 6.5%, while in women not living with HIV/Aids was 2.9%. Among women living with HIV/Aids, the following were associated with induced abortion in the multivariable analysis: being older, having a higher education level, having had more sexual partners (i.e., variables linked to the life course of women), having had children prior to the index pregnancy and living with a sexual partner during pregnancy (i.e., variables linked to the context of each pregnancy). On the other hand, among women not living with HIV/Aids, only having a higher education level and having had more sexual partners (i.e., determinants linked to the life course of women) were associated with voluntary pregnancy termination in multivariable analysis.

Conclusion

Although determinants are similar between women living and not living with HIV/Aids, prevalence of induced abortion is higher among pregnancies in women living with HIV/Aids, pointing to their greater social vulnerability and to the need for public policy to address prevention and treatment of HIV associated with reproductive issues.     

Blood Coagulation Changes during Mid-trimester Abortion Induced by Prostaglandin F2α

Serial studies on the coagulation system were made during second-trimester abortion induced by extra-amniotic, intra-amniotic, vaginal, and intravenous prostaglandin F₂α. No significant changes were found in the prothrombin time, partial thromboplastin time, or levels of fibrin-fibrinogen degradation products. An increase in the activity of factor X occurred with all routes of administration; the activity of factor VIII increased during extra-amniotic, vaginal, and intravenous administration; factor V activity increased during extra-amniotic and vaginal administration; and the activity of factor VII-X complex increased slightly at the time of abortion with all methods.The findings suggest that though prostaglandin induction of second-trimester abortion produces changes in the coagulation system the effects are much less than those which accompany induction of abortion by hypertonic saline or abdominal delivery in late pregnancy.     

Sociodemographic Trends in the Incidence of Pancreatic and Biliary Tract Cancer in UK Primary Care

Background

The UK incidence of pancreatic ductal adenocarcinoma (PDAC) is approximately 9/100,000 population compared with 1–2/100,000 for biliary tract cancer (BTC). This study explores the incidence of these cancers over time and the influence of socio-demographic and geographic factors in a UK primary care cohort.

Methods

This study uses data from a large UK primary care database, The Health Improvement Network (THIN). All adult patients contributing data to THIN between January 2000 and December 2010 were included. Annual incidence rates were calculated, adjusted for age, gender, time period, deprivation score (Townsend quintile) and strategic health authority.

Results

From 2000–2010, the annual incidence of PDAC increased by an average of 3% per year (95% CI 1.00–4.00%) and BTC by 4% (95% CI 2.00–6.00%). Incidence of both cancers increased steeply with age and was higher in men. BTC was associated with increasing deprivation (most deprived versus least deprived quintile (OR: 1.45 [95% CI: 1.17, 1.79.]).

Conclusions

The overall incidence of both cancers is low but increasing. Variations in incidence may reflect changes in coding practice or increased exposure to associated risk factors.     

Bax/Bcl-2 mRNA在恒河猴药物流产胎盘中的表达

目的：通过检测重要的细胞凋亡调节因子Bax和Bcl-2的表达,探讨恒河猴胎盘细胞凋亡与药物流产的关系。方法：利用RT-PCR和原位杂交的方法检测恒河猴对照组和药物流产组(RU-486与AG诱导)胎盘中Bax和Bcl-2mRNA的表达。结果：Bax mRNA在流产胎盘中的表达量明显高于对照组胎盘。在胎盘绒毛滋养层细胞可见明显表达,基底层蜕膜细胞也有表达。Bcl-2mRNA在流产胎盘中的表达量明显低于对照组胎盘,表达部位与Bax类似。结论：RU-486和AG可能通过上调Bax mRNA和下调Bcl-2mRNA的表达,导致胎盘组织凋亡细胞的数量明显增加,从而影响胎盘的正常结构和功能,增加了流产的危险性。     

Enviromentally Induced Changes in Clamp Connection Incidence in Hyphal Branching Systems of Coprinus disseminatus

The incidence of clamp connections among surface hyphae at thecolony margin of apparent dikaryons from four stocks of Coprinusdisseminatus has been investigated under several environmentalconditions. On 2 per cent malt agar, clamp connections are formed at allnodes of the main leader hyphae, but they are absent from theearlier-formed nodes of primary branch hyphae. Most primarybranches have begun to form clamp connections by their fifthcell division, and continue to do so subsequently. Onset ofclamp connection formation in primary branches is delayed whenthe concentration of malt in the medium is reduced. The occurrenceof clamp connections on main leader hyphae is reduced or preventedwhen nutrient supply in the medium is reduced, or when the mediumis ‘pre-staled’ by previous growth of C. disseminatus.Clamp-free main hyphal tips revert to formation of clamp connectionswhen the intact hyphal system is transferred to more favourableenvironmental conditions. Presence of clamp connections on bothmain and branch hyphae is associated with high hyphal diameter,and in some instances, also with high hyphal extension rate. The significance of these observations to mechanisms of growthof hyphal branching systems and their relevance to other speciesthat form clamp connections intermittently, are discussed.

Modifying Post-Operative Medical Care after EBV Implant May Reduce Pneumothorax Incidence

ObjectiveEndoscopic lung volume reduction (ELVR) with valves has been shown to improve COPD patients with severe emphysema. However, a major complication is pneumothoraces, occurring typically soon after valve implantation, with severe consequences if not managed promptly. Based on the knowledge that strain activity is related to a higher risk of pneumothoraces, we asked whether modifying post-operative medical care with the inclusion of strict short-term limitation of strain activity is associated with a lower incidence of pneumothorax.MethodsSeventy-two (72) emphysematous patients without collateral ventilation were treated with bronchial valves and included in the study. Thirty-two (32) patients received standard post-implantation medical management (Standard Medical Care (SMC)), and 40 patients received a modified medical care that included an additional bed rest for 48 hours and cough suppression, as needed (Modified Medical Care (MMC)).ResultsThe baseline characteristics were similar for the two groups, except there were more males in the SMC cohort. Overall, ten pneumothoraces occurred up to four days after ELVR, eight pneumothoraces in the SMC, and only two in the MMC cohorts (p=0.02). Complicated pneumothoraces and pneumothoraces after upper lobe treatment were significantly lower in MMC (p=0.02). Major clinical outcomes showed no significant differences between the two cohorts.ConclusionsIn conclusion, modifying post-operative medical care to include bed rest for 48 hours after ELVR and cough suppression, if needed, might reduce the incidence of pneumothoraces. Prospective randomized studies with larger numbers of well-matched patients are needed to confirm the data.     

Incidence and Predictors of Adolescent's Early Sexual Debut after Three Decades of HIV Interventions in Tanzania: A Time to Debut Analysis

Purpose

To determine the incidence and predictors of adolescent’s early sexual debut after three decades of HIV interventions in Tanzania.

Methods

In a cross-section study of adolescents aged 16–19 residing in Morogoro Municipality, information on socio-demographic, parental-and-peer communication, and sexual behaviors were collected. Cox-regression analysis was used to examine predictors of time to sexual debut.

Results

A total of 316 adolescents with mean age of 17.5±0.9 were recruited. Half (48.7%) of adolescent were sexually active with mean age at sexual debut of 14.6±2.3. Of these, 57.8% had sex before their 15^th birthday with incidence of early sexual debut of 17.4/1000 person-years at risk. Adolescent family characteristics, peer pressure, alcohol use, parental and peer communication were key predictors of early sexual debut.

Conclusion

Parental and peer communication strategies works calling for efforts to increase its scope to reach all adolescents alongside promoting family stability and reducing adolescent alcohol consumption.
