Risk and Protective Factors for Intimate Partner Violence Against Bisexual Victims: A Systematic Scoping Review

Bisexual-identifying individuals appear to be at increased risk of experiencing intimate partner violence (IPV) compared to people of other sexualities. The purpose of this systematic scoping review was to examine risk and protective factors for the perpetration of IPV against bisexual victims and to provide a preliminary quality assessment of the included studies. A systematic search of academic and grey literature was conducted in February 2021. Inclusion criteria specified that study participants identified as bisexual, that the study examined risk or protective factors for IPV, and that findings were disaggregated by sexual identity. All potentially eligible references were independently screened by two reviewers, and conflicts settled by a third reviewer. Nine articles published between 2013 and 2021 met criteria for inclusion. Data extraction was completed for all included studies, and findings presented in a narrative synthesis. The review identified a number of risk factors, including bisexual identity, internalised homophobia, discrimination, partner gender, negative childhood experiences and non-monogamy. One study included consideration of a potentially protective factor. The majority of the included studies were cross-sectional in design. More longitudinal studies are needed to clarify temporality of the associations identified and better inform support and prevention efforts. Further implications for future research, policies and practise are discussed.

“She is courageous because she does not care what people think about her…”: attitudes toward adolescent contraception use among Rwandan family planning providers and adult female modern contraceptive users

Introduction

In Rwanda, only 20% of sexually active unmarried young women use family planning as compared to 64% of married women. Adolescence is an important time of growth and development that often includes the initiation of sexual activity. Sexually active adolescents need support in accessing contraceptive services to prevent negative health outcomes. In sub-Saharan Africa, the adolescent population represents a large share of the total population and that proportion is predicted to expand over time. Adolescent contraceptive needs have largely been unmet, and with growing numbers, there is increased potential for negative health sequelae. Due to the low use of contraception by adolescents in Rwanda, and the growing population of adolescents, this study aims to explore the perspectives of family planning providers and adult modern contraceptive users on adolescent contraceptive use. Inclusion of adult community members in the study is a unique contribution, as research on adolescent contraceptive use in sub-Saharan Africa relies primarily on perspectives from adolescents and family planning providers.

Methods

This qualitative study in 2018 utilized 32 in-depth interviews with modern contraceptive users and eight focus group discussions with family planning providers. Respondents were from Musanze and Nyamasheke districts in Rwanda, the districts with the highest and lowest modern contraceptive use among married women, respectively. Coding was conducted in Atlas.ti.

Results

Stigma regarding premarital sex results in barriers to adolescent access to contraceptive services. Family planning providers do provide services to adolescents; however, they often recommend secondary abstinence, offer a limited method selection, and accentuate risks associated with sexual activity and contraceptive use. Providers support adolescent clients by emphasizing the need for privacy, confidentiality, and expedient services, particularly through youth corners, which are spaces within health facilities designed to meet youth needs specifically. Modern contraceptive-using adult female community members advocate for youth access to contraception, however mothers have mixed comfort discussing sexual health with their own youth.

Conclusion

To destigmatize premarital sexual activity, government efforts to initiate communication about this topic must occur at national and community levels with the goal of continued conversation within the family. The government should also train family planning providers and all health personnel interacting with youth on adolescent-friendly health services. Dialogue between community members and family planning providers about adolescent access to contraceptive services could also reduce barriers for adolescents due to community members’ generally supportive views on adolescent contraceptive use. Efforts to engage adolescent caregivers in how to talk to youth about sex could also contribute to expanded use.

In Rwanda, youth who are having sex use family planning less than married women. This study involved asking family planning providers and adults what they think about youth using family planning. Data for this study was collected in 2018, and included 32 interviews with adult family planning users and eight group discussions with family planning providers in two areas of Rwanda. The findings show that Rwandans believe youth should not have sex before they are married. Family planning providers do provide youth with services; however, they often push stopping sexual activity, offer a smaller selection of family planning methods, and exaggerate risks associated with sex and family planning use. Family planning providers support youth by honoring their need for privacy, keeping their secrets, and providing fast services so fewer people see them at the clinic. Providers like to help adolescents in youth corners, which are special spaces within health facilities just for youth. Importantly, adult women who use family planning want youth in their community to be able to use family planning, too. In order to respond to the issues raised, the Rwandan government can start conversations in villages and more broadly about the need for youth to have access to family planning. The government should also teach family planning providers and anyone who comes into contact with youth to offer helpful and friendly services. Setting up spaces for adults to talk with family planning providers about youth access to family planning could also contribute to fewer barriers to services for adolescents.

Family planning demand generation in Rwanda: Government efforts at the national and community level impact interpersonal communication and family norms

Between 2005 and 2020, total contraceptive use among married women in Rwanda increased from 17% to 64%. The aim of this study is to better understand how the Rwandan government’s mobilization and demand generation efforts have impacted community norms and interpersonal discourse surrounding family planning. Eight focus group discussions with family planning providers and 32 in-depth interviews with experienced modern contraceptive users were conducted in 2018 in the two Rwandan districts with the highest and the lowest contraceptive prevalence rates. Results suggest that outspoken government support, mass media, and community meetings were valuable sources of information about family planning. Information received through these channels generated interpersonal dialogue about contraceptives through both conversation and observation; however, rumors and misinformation remained a significant barrier to use. A once taboo subject is now normative among married couples. Continuing to address common fears and misinformation through communication channels such as mass media and community meetings may help to further increase contraceptive uptake in Rwanda.

A Scoping Review of the Health Impact of the COVID-19 Pandemic on Persons Experiencing Homelessness in North America and Europe

Persons experiencing homelessness (PEH) are at heightened risk for infection, morbidity, and mortality from COVID-19. However, health consequences of the pandemic extend far beyond those directly caused by the virus. This scoping review aimed to explore the impacts of the COVID-19 pandemic on the health and well-being of PEH in North America and Europe. A systematic search of academic and grey literature was conducted in September 2021. To be included, studies had to include primary data related to the impact of the pandemic on health or well-being of PEH and be written in English. All potentially relevant references were independently screened by two reviewers, and minor conflicts were settled with input of a third reviewer. A total of 96 articles met criteria for inclusion. Data extraction was completed for all included studies, and findings synthesised and presented thematically. Numerous health impacts of the pandemic on PEH were identified, including SARS-CoV-2 infection, morbidity, mortality, and hospitalisation, fear of infection, access to housing, hygiene, PPE, food, as well as mental health, substance use, other health-related outcomes and treatment services. Gaps in the literature relating to persons using alcohol, access to mental health support, and violence were also identified. Implications for future research are discussed.

"…the availability of contraceptives is everywhere.": coordinated and integrated public family planning service delivery in Rwanda

Background

Contraceptive use in Rwanda tripled since 2005. This study aims to understand the role of coordinated and integrated public family planning service delivery in achieving this increase in contraceptive use in Rwanda.

Methods

This qualitative study in 2018 included eight focus group discussions with family planning providers and 32 in-depth interviews with experienced family planning users.

Results

Results indicate a well-coordinated public family planning service delivery system with community health workers and nurses filling different and complementary roles in meeting family planning client needs at the local level. In addition, integration of family planning into other maternal and child health services is the norm.

Conclusions

The coordination and integration of family planning across both providers and services may help explain the rapid increase in Rwanda’s contraceptive use and has potential applications for enhancing family planning service delivery in other settings.

Family planning use increased from 17 to 53% in Rwanda in between 2005 and 2015. The purpose of this study is to understand the roles of two types of family planning workers in providing family planning services, how those providers work together to achieve the goal to provide public services, and how the Rwandan health system includes family planning services in a variety of other types of health services. To achieve the study purpose, 32 women with experience using modern methods of contraception were interviewed. In addition, 88 providers participated in eight group discussions to discuss these topics. The results from the interviews and group discussions showed that family planning services are easy to access for Rwandans—due to two types of family planning providers filling different roles to assist Rwandans start and keep using family planning methods. Family planning services are included in services for pregnant, delivering, and postpartum mothers—as well as services for infants and children. These are all times when those adults using the services would also be in need of family planning services. The family planning service delivery team approach—as well as including family planning services in mother’s and children’s health services likely helps explain the increase in family planning use in Rwanda. Other nations might learn from Rwanda’s service delivery approach to family planning to also increase access to family planning for their citizens.

Family planning providers and contraceptive users in Rwanda employ strategies to prevent discontinuation

BACKGROUND

In Rwanda, nearly a third of contraceptive users discontinue within the first year of use. Family planning programs often focus more on recruitment of new users as opposed to maintaining use among current users. A focus on sustaining users and minimizing discontinuation is imperative for long-term family planning program success. This study explores the efforts providers and contraceptive users in Rwanda employ to prevent one of the greatest challenges to family planning programs: contraceptive discontinuation.

METHODS

This was a qualitative study conducted in Rwanda between February and July 2018. It included eight focus group discussions with 88 family planning providers and 32 in-depth interviews with experienced modern contraceptive users. Data were collected in two districts with the highest (Musanze) and lowest (Nyamasheke) rates of contraceptive use. Data were analyzed using thematic content approach.

RESULTS

Family planning providers in this study used the following strategies to prevent discontinuation: counseling new users on the potential for side effects and switching, reminding clients about appointments for resupply, as well as supporting dissatisfied users by providing counseling, medicine for side effects, and discussing options for switching methods. Users, on the other hand, employed the following strategies to prevent discontinuation: having an understanding that experiences of side effects vary by individuals, supporting peers to sustain use, persisting with use despite experiences of side effects, and switching methods.

CONCLUSIONS

The strategies used by family planning providers and users in Rwanda to prevent discontinuation suggest the possibility of long-term sustained use of contraception in the country. Harnessing and supporting such strategies could contribute to sustaining or improving further contraceptive use in the country.

An examination of the barriers to and benefits from collaborative couple contraceptive use in Rwanda

Background

Supportive male involvement is strongly correlated with contraceptive use. In Rwanda, where the contraceptive prevalence rate among married women increased from 17 to 52% from 2005 to 2010, and stagnated at 53% in 2015, understanding the role of male partners in collaborative couple contraceptive use can help inform programs designed to further increase the use of contraception in Rwanda.

Methods

This study utilized qualitative methods in 2018, specifically 32 in-depth interviewers with mostly current users of modern contraceptive methods and eight focus group discussions with family planning providers—both family planning nurses and community health workers (CHWs). Respondents were from Musanze and Nyamasheke Districts, the districts with the highest and lowest modern contraceptive use, respectively, to explore the role of couple collaboration in family planning use in Rwanda. Data were analyzed using the thematic content approach in Atlas.ti (8).

Results

Findings demonstrate that some men are opposed to use of male methods of contraception, and some are opposed to any contraceptive use, which can lead to covert use. Women and providers prefer collaborative couple contraceptive use—as a result, providers advocate for and encourage male partner participation in contraceptive use. Women are most often burdened with seeking out information, initiating discussions, and sharing information discovered about contraceptive use with partners. Decision-making about contraceptive use, once discussed, can be collaborative and motivated by financial considerations. When couple contraceptive use is collaborative, benefits range from marital harmony to husband’s support of sustained use through reminders about appointments, joint counseling, and support in managing side effects.

Conclusion

Family planning providers at the community and clinic levels encourage collaborative contraceptive use among couples and some Rwandan couples communicate well about family planning use. Despite the positives, women are expected to source family planning information, share that information with their male partners, seek out family planning services, and use family planning. If more Rwandan male partners accepted use, used male methods of contraception, and participated even more in the work it takes to use family planning, the potential for sustained, and even enhanced, contraceptive use in Rwanda could be realized.

"… the way we welcome them is how we will lead them to love family planning.": family planning providers in Rwanda foster compassionate relationships with clients despite workplace challenges

BACKGROUND

Rwanda has markedly increased the nation's contraceptive use in a short period of time, tripling contraceptive prevalence in just 5 years between 2005 and 2010. An integral aspect of family planning programs is the interactions between family planning providers and clients. This study aims to understand the client-provider relationship in the Rwandan family planning program and to also examine barriers to those relationships.

METHODS

This qualitative study in Rwanda utilized convenience sampling to include eight focus group discussions with family planning providers, both family planning nurses and community health workers, as well as in-depth interviews with 32 experienced modern contraceptive users. Study participants were drawn from the two districts in Rwanda with the highest and lowest modern contraceptive rates, Musanze and Nyamasheke, respectively Data analysis was guided by the thematic content approach, Atlas.ti 8 was utilized for coding the transcripts and collating the coding results, and Microsoft Excel for analyzing the data within code.

RESULTS

Data analysis revealed that, despite workplace related challenges - including inadequate staffing, training, and resources, relationships between providers and clients are strong. Family planning providers work hard to understand, learn from, and support clients in their initiation and sustained use of contraceptives.

CONCLUSION

Given the existing context of purposeful efforts on the part of family planning providers to build relationships with their clients, if the current level of government support for family planning service provision is enhanced, Rwanda will likely sustain many current users of contraception and engage even more Rwandans in contraceptive services in the future.

A Rapid Realist Review of Group Psychological First Aid for Humanitarian Workers and Volunteers

Humanitarian workers are at an elevated risk of occupational trauma exposure and its associated psychological consequences, and experience increased levels of anxiety, depression, and post-traumatic stress disorder (PTSD) compared to the general population. Psychological first aid (PFA) aims to prevent acute distress reactions from developing into long-term distress by instilling feelings of safety, calmness, self- and community efficacy, connectedness and hope. Group PFA (GPFA) delivers PFA in a group or team setting. This research sought to understand 'What works, for whom, in what context, and why for group psychological first aid for humanitarian workers, including volunteers?' A rapid realist review (RRR) was conducted. Initial theories were generated to answer the question and were subsequently refined based on 15 documents identified through a systematic search of databases and grey literature, in addition to the inputs from a core reference panel and two external experts in GPFA. The findings generated seven programme theories that addressed the research question and offered consideration for the implementation of GPFA for the humanitarian workforce across contexts and age groups. GPFA enables individuals to understand their natural reactions, develop adaptive coping strategies, and build social connections that promote a sense of belonging and security. The integrated design of GPFA ensures that individuals are linked to additional supports and have their basic needs addressed. While the evidence is sparce on GPFA, its ability to provide support to humanitarian workers is promising.

Loratadine/pseudoephedrine for nasal symptoms in seasonal allergic rhinitis: a double-blind, placebo-controlled study

In this double-blind, placebo-controlled, crossover, parallel study, we treated 20 adults who had seasonal allergic rhinitis with once-daily fixed-combination loratadine/pseudoephedrine sulfate to observe its effect on relieving symptoms, primarily nasal congestion. Acoustic rhinometry detected a trend toward improvement in nasal patency, although the difference between pre- and post-treatment measures was not statistically significant. Endoscopic inferior turbinate photography documented that treatment led to statistically significant reductions in the amount of nasal edema and nasal secretions. The results of a quality-of-life questionnaire suggested that treatment alleviated nasal and ocular symptoms of rhinoconjunctivitis. An analysis of subjective visual analog scale scores showed a trend toward improvement in most but not all nasal symptoms. We conclude that once-a-day fixed-combination loratadine/pseudoephedrine is effective in relieving nasal congestion in patients with seasonal allergic rhinitis.

Acoustic rhinometric measurements of changes in velar positioning

Acoustic rhinometry as a means to detect changes in velar position was examined in this study. Videofluoroscopic recordings were made of two normal speakers maintaining velopharyngeal open and velopharyngeal closed (silent /f/) targets. Simultaneous acoustic rhinometric recordings were made during the production of each stimulus. Determinations of changes in velar positioning during the closed samples were made from fluoroscopic recordings and compared to nasal cavity-nasopharynx changes detected by rhinometry. The excellent agreement between the measures from the two procedures (less than 1 cm) indicates that acoustic rhinometry is capable of detecting changes in velar positioning during "silent" speech. Implications for assessment and future research are discussed.

ucb 11056, a new potential nootropic drug, amplifies induced cyclic AMP formation in rat brain tissue

ucb 11056 [2-(4-morpholino-6-propyl-1,3,5-triazin-2-yl)aminoethanol] induced a significant (approximately 25%) increase in cyclic AMP levels in different brain areas following its intraperitoneal injection. This effect started as early as 2 min postinjection and lasted for 30 min, after which cyclic AMP levels returned to normal. In hippocampal slice preparations in vitro, ucb 11056 exerted a strong potentiation of cyclic AMP levels when it was combined with agents such as norepinephrine, forskolin, and isoproterenol. Only a slight effect on cyclic AMP levels was measured when ucb 11056 was incubated alone with hippocampal slices. The potentiating effect of ucb 11056 on norepinephrine-stimulated cyclic AMP formation was partially reduced when slices were pretreated with yohimbine and totally abolished when slices were treated with propranolol. These combined data indicate that (a) ucb 11056 rapidly increases cyclic AMP levels in the rat brain in vivo and (b) ucb 11056 potentiates stimulated cyclic AMP formation in vitro. The data also suggest that the central effect of ucb 11056 might be via the modulation of cyclic AMP generation, most probably mediated through adenylate cyclase activation mechanisms combined with a weak inhibitory activity on the cyclic nucleotide phosphodiesterase activity.

Fatal lung abscess due to Lactobacillus casei ss rhamnosus

A fatal case of community acquired pneumonia due to Lactobacillus casei ss rhamnosus is reported. Clinicians should be aware of this type of pneumonia.

Reversible cholinergic changes induced by AF64A in rat hippocampus and possible septal compensatory effect

Ethylcholine aziridinium (AF64A) was injected intracerebroventricularly in rats, and the dose- and time-dependent effect of this treatment was measured on cholinergic markers in different areas of the brain. Choline acetyltransferase (ChAT) in the hippocampus was reduced by 0, 25, 40 and 50%, 4 days after administration of 0.25, 0.5, 1.0 and 2.0 nmol/side of AF64A. This effect was paralleled by a 0, 21, 38 and 48% increase in septal ChAT, at the same time and dose, respectively. Hippocampal and septal ChAT returned to normal by 14 days, following the two smaller doses of AF64A. Normal values of ChAT activity in the hippocampus were measured by 3 months post-1.0 nmol/side and by 12 months after 2.0 nmol AF64A/side. A transient secondary increase in septal ChAT was measured at 28 and 42 days after 1.0 nmol/side, after which no further changes were measured in this area. High affinity choline transport (HAChT) in the hippocampus showed a 35 and 25% decrease but only 14 and 7 days, after injection of 0.25 and 0.5 nmol AF64A/side, respectively. However, significant reductions by 45% at 14 days and by 65% at 4 days, were measured after the infusion of 1.0 and 2.0 nmol/side, respectively. This effect was significantly attenuated by 3 months and returned to normal by 12 months after treatment. Acetylcholinesterase (AChE) activity in the hippocampus was most severely affected by AF64A. Specifically, significant inhibition of 20% (by 7 days), 35% (by 7 days), 25% (by 2 days) and 30% (by 2 days) was observed at 0.25, 0.5, 1.0 and 2.0 nmol AF64A/side, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute and chronic studies with the anticholinesterase Huperzine A: effect on central nervous system cholinergic parameters

High affinity choline transport, choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) were assessed in rats after acute and chronic administration of the AChE inhibitor Huperzine A. Acute treatment: Forty-five min after a single injection of Huperzine A (0.5 mg/kg i.p.) the activity of AChE was significantly decreased by 15-30% in hippocampus, striatum and septum. The activity of ChAT was not altered. In the hippocampus high affinity choline transport was attenuated by 25%, whereas no effect in the striatum was observed. After 90 min, both inhibition of AChE and attenuation of high affinity choline transport had returned to control values. A dose of 0.1 mg/kg (i.p.) did not produce significant effects. Similar results were obtained with physostigmine (0.25 mg/kg), although the duration of inhibition of AChE was shorter than that with Huperzine A. Chronic treatment: After 5 days (twice a day), at 0.5 mg/kg, the activity of AChE was significantly reduced by 20-30% in every region of the brain studied. High affinity choline transport in the hippocampus was reduced by 28%, 45 min after the last injection, but in the striatum there was no effect. The activity of ChAT was not affected in any region of the brain studied. Thus, acute or chronic treatment with Huperzine A: did not alter ChAT; reduced high affinity choline transport in the hippocampus in a transient manner; and had a longer duration of action as an AChE inhibitor than physostigmine. Moreover, tolerance to low-toxicity doses of Huperzine A was minimal, contrary to what has been observed with other inhibitors of AChE.

Sector-dependent neurotoxicity of ethylcholine aziridinium (AF64A) in the rat hippocampus

The present study was aimed at measuring the distribution of ethylcholine aziridinium (AF64A)-induced cholinotoxicity within the hippocampus 6 days after bilateral (icv) administration of 1, 2 or 3 nmol, or vehicle. The dissected hippocampus was sectioned with a vibratome into 5 parallel sectors distributed along its long axis from its thalamic surface (medial) to its cortical surface (lateral). In vehicle-treated rats, the high affinity cholinergic transport (HAChT), choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) activities were distributed according to a gradient of increasing activity, extending from the lateral to the medial surface of the hippocampus. After treatment with AF64A, the normal gradient of enzyme activity was profoundly disrupted at all doses of AF64A and the core sectors of the hippocampus were significantly more affected than the superficial sectors. The HAChT gradient was progressively abolished with increasing doses of toxin, and the effect was maximal at 2 nmol.

Osteoblast low-molecular-weight proteinase inhibitor. I. Isolation and characterization of activity from osteoblastic cells and bone

Isolated mouse calvarial cells having phenotypic characteristics of osteoblasts, mouse parietal bone segments, mouse serum, and control mouse lung fibroblasts were extracted in NaCl and ultrafiltered to recover final concentrates having nominal molecular weights between 50,000 and 1000 daltons. Final concentrates of osteoblasts and bone but not of serum or control fibroblasts were positive for the inhibition of trypsin degradation of fibrin. Osteoblast final concentrates inhibited trypsin hydrolysis of the synthetic substrate p-tosyl-L-arginine methyl ester. Osteoblast and bone final concentrates comigrated with Trasylol but were electrophoretically distinct from alpha 1-antiproteinase. Final concentrates of osteoblast and bone extracts did not inhibit tadpole collagenase using the [3H]glycine-labeled diffuse chick collagen fibril assay. High-performance liquid chromatography (HPLC) of osteoblast final concentrates after purification using immobilized trypsin affinity chromatography revealed the presence of a major peak that was positive for the inhibition of trypsin. Molecular weight determination by HPLC indicated that the inhibitor(s) range in nominal molecular weight from 4300 to 5100 daltons. The presence of low-molecular-weight serine proteinase inhibitory activity in bone suggests its participation in the regulation of bone resorption through the regulation of enzyme activation of collagenase, and possibly its role in defense against bone matrix enzymatic degradation during tumor cell invasion.

Ludwig's angina. Report of a case and review of the literature

In the preantibiotic era, Ludwig's angina frequently caused asphyxiation and death. Recognized less often today, this rapidly progressive submaxillary cellulitis may still be fatal. A case associated with Haemophilus influenzae bacteremia in an adult is presented. Twelve additional cases of cellulitis of the neck in adults with H influenzae bacteremia are summarized. One hundred forty-one cases of Ludwig's angina reported since 1945 are reviewed and compared with 315 earlier cases. In the cases reported in the antibiotic era, the mean age of the patients was 29 years. Most patients were previously healthy but had evidence of dental disease. Submandibular swelling, elevation of the tongue, fever, dysphagia, and trismus were each present in more than one half of patients. Streptococci and anaerobes were most frequently isolated from soft-tissue cultures. Untreated, this illness is fatal in one half of patients. Early recognition is therefore essential. Appropriate therapy includes maintenance of the airway, antibiotics, and surgical drainage when indicated.

Low molecular weight proteinase inhibitors. III. Quantification and isolation of activity from benign and malignant human breast tissue samples

Both normal and malignant breast tissue contain proteinase inhibitors. Extracellular proteins produced by tumors have been demonstrated to be qualitatively similar to their counterparts in normal tissue, but they are often present in significantly less quantity than in normal tissue. In our investigation, normal breast tissue extracts were shown to contain significantly greater inhibitory activity directed against the degradation of casein by trypsin in the isolated fraction of the extracts compared with extracts from malignant tissues. The molecular weight of this isolated fraction is approximately 17,000 daltons. Our observations suggest that malignancy is accompanied by a reduction in the net inhibitory activity of this proteinase inhibitor.
