Abstract
INTRODUCTION Hereditary angioedema (HAE) is a rare genetic disorder characterized by recurrent edema and predominantly caused by the dysregulation of the kinin-kallikrein system. AREAS COVERED This manuscript presents the results of preclinical and early clinical trials of newer drugs targeting the dysregulated kinin-kallikrein system. ATN-249 is an oral drug that has shown promising results in preclinical and Phase I studies, and good tolerability in the prophylactic treatment of attacks. KVD900 is also an oral agent developed for the on-demand treatment of HAE attacks. It has shown positive results in Phase I/II studies, with rapid absorption. The third drug, IONIS-PKKRx, is an antisense oligonucleotide targeting plasma prekallikrein mRNA. It has shown a dose-dependent reduction of plasma prekallikrein levels and proenzyme activation in Phase I/II studies, and has shown promising results. STAR-0215 is a long acting anti-activated kallikrein monoclonal antibody. A Phase 1a single ascending dose trial evaluated its safety, pharmacokinetics, and pharmacodynamics. Lastly, NTLA-2002 is an investigational gene-editing therapy. EXPERT OPINION The targeted treatment of the dysregulated kinin-kallikrein system with specific inhibitors is promising for the prevention of angioedema attacks. Ongoing phase III studies will provide further insight into the efficacy and long-term safety of these novel therapies, potentially expanding treatment options for HAE treatment.

A qualitative study on the clinical safety and user experiences of female condoms for anal intercourse among men who have sex with men in Shanghai, China. Front Public Health 2023; 11:1243891. [PMID: 38074717 PMCID: PMC10701689 DOI: 10.3389/fpubh.2023.1243891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 10/19/2023] [Indexed: 12/18/2023] Open
Abstract
Objective This qualitative study aimed to understand the clinical safety, efficacy, and receptiveness of using the female condom (FC) during anal intercourse among men who have sex with men (MSM). Methods Subjects for this study were recruited from a two-group crossover trial among MSM in Shanghai. The trial consisted of two phases, each including the use of condoms (FC vs. male condom), questionnaires, and in-depth one-on-one interviews. The two phases were separated by a washout period of 4 weeks. The minimum sample size for this study was determined in accordance with the principle of "information saturation." The qualitative data were organized and analyzed using ATLAS.ti version 7. Results A total of 26 participants from the MSM population were recruited for this study, with 10 assuming the insertive role (i.e., "1"), 8 assuming the receptive role (i.e., "0"), and 8 being versatile (i.e., "0.5"). Each participant completed the crossover trial comprising two phases. The cumulative usage of FCs and male condoms (MCs) amounted to 115 and 127 times, respectively. During the reported sexual encounters, no participants reported incidents of condom rupture, slippage, or other malfunctions. A few participants reported experiencing slight chafing pain, primarily put forward by "0" participants. Apart from those reports, no instances of bleeding, swelling, or allergic reactions were reported. The efficiency of FC in disease prevention, the sexual partner's willingness to use FC, the freshness of FC, and positive sexual experiences were the main reasons for the consistent use of FC for anal sex. Discomfort and pain during sexual activity, the loose design and thick material of FCs, and difficulties in placing FCs were the major obstacles to FC use among MSM. The elements referring to the forehead exhibited varied in importance among "1,", "0," and "0.5" participants. Regarding the willingness to use the FC in the future anal intercourse, 61.54% of participants expressed a positive inclination, 23.08% were uncertain, and 15.38% stated that they would not. "A better sense of security during anal sex" was the main factor affecting willingness among "0" participants and "the sexual pleasure that the FC brought" among "1" participants. Improving the design and technology of FCs and increasing the frequency of use and practice might improve the use skills, which will favor the willingness to use FCs among the MSM population. Conclusion FCs received positive user feedback from study participants, but distinctions were found in individuals in different sexual roles. Large-scale quantitative studies are needed to evaluate the clinical safety of the FC and its effectiveness in preventing the transmission of STDs during anal intercourse.

Abstract
The COVID-19 pandemic disproportionately affected Native American people and communities across the United States. Despite unequal losses during the pandemic, Native Americans have high vaccination rates. We provide insight into perspectives of COVID-19 and vaccinations through in-depth interviews with Native Americans. Through this research, we provide a holistic view of how Native Americans perceive vaccines by pairing Indigenous perspectives of risk and the Health Belief Model. We discuss the importance of tribal sovereignty in developing health communication strategies, and the need for messaging that is trusted and culturally appropriate.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:4779.

Abstract
Condom-related stigma is a frequently mentioned barrier to consistent condom use among men who have sex with men (MSM). Based on the concept and operational definition of condom-related stigma recently defined by our team, we developed the 20-item condom-related stigma scale (CRSS) and examined its psychometric properties among 433 MSM in China, following DeVellis's scale development guidelines. The content validity, convergent validity, empirical validity, factorial validity, scale score reliability, split-half reliability, and test-retest reliability for the CRSS were all assessed. The scale consists of four domains: perceived distrust, perceived potential HIV/STI risk, perceived embarrassment, and perceived violation of the traditional understanding of sexual intercourse. The CRSS has good validity (the scale-level content validity index was 0.99; the empirical validity was greater than 0.70) and high reliability (the Cronbach's alpha coefficient overall was 0.926; the split-half reliability overall was 0.795; the test-retest reliability overall was 0.950). This scale is recommended for assessing the level of condom-related stigma among Chinese MSM, which can serve as an evaluating indicator for safer-sex interventions to prevent HIV infection among the MSM population in a Chinese cultural context.

Abstract
Abstract
Background
Despite a large amount of behavioral interventions to reduce human immunodeficiency virus (HIV)-related high-risk sexual behaviors, consistent condom use remains suboptimal among men who have sex with men (MSM). However, current databases are lack of synthesized evidence to explain why MSM practiced condomless sex.
Objective
Our study aims to conduct a systematic review and meta-synthesis of 39 eligible qualitative studies to explore the barriers to condom use among MSM.
Methods
A systematic review and meta-synthesis of qualitative studies (1994–2021). On March 4, 2021, a comprehensive search was conducted in 14 electronic databases. The study was conducted based on the Joanna Briggs Institute’s recommendations.
Results
Thematic analysis produced six synthesized themes, which were classified into three levels according to the Social-ecology Model. Individual level barriers to condom use included physical discomfort, lack of HIV/STI-related knowledge and substance use; interpersonal-level barrier was mainly the condom stigma, namely regarding using condom as symbols of distrust or HIV/sexually transmitted infections (STIs) prevention, or as violating traditional cognition of sex, or as an embarrassing topic; environmental/structural-level barriers included situational unavailability, unaffordability of condoms and power imbalance in the sexual relationship.
Conclusion
This meta-synthesis offered in-depth understanding of condom use barriers for MSM and could guide the development of multifactorial interventions according to the identified barriers, especially targeting to reduce condom stigma, which has not been focused and intervened previously.

BMC Pregnancy Childbirth 2021; 21:618. [PMID: 34503471 PMCID: PMC8431849 DOI: 10.1186/s12884-021-04092-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 08/29/2021] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Obstetric interventions performed during delivery do not reflect improvements in obstetric care. Several practices routinely performed during childbirth, without any scientific evidence or basis - such as Kristeller maneuver, routine episiotomy, and movement or feeding restriction - reflect a disrespectful assistance reality that, unfortunately, remains in place in Brazil. The aims of the current study are to assess the coexistence and prevalence of obstetric interventions in maternity hospitals in Belo Horizonte City, based on the Grade of Membership (GoM) method, as well as to investigate sociodemographic and obstetric factors associated with coexistence profiles generated by it. METHODS Observational study, based on a cross-sectional design, carried out with data deriving from the study "Nascer em Belo Horizonte: Inquérito sobre o Parto e Nascimento" (Born in Belo Horizonte: Survey on Childbirth and Birth). The herein investigated interventions comprised practices that are clearly useful and should be encouraged; practices that are clearly harmful or ineffective and should be eliminated; and practices that are inappropriately used, in contrast to the ones recommended by the World Health Organization. The analyzed interventions comprised: providing food to parturient women, allowing them to have freedom to move, use of partogram, adopting non-pharmacological methods for pain relief, enema, perineal shaving, lying patients down for delivery, Kristeller maneuver, amniotomy, oxytocin infusion, analgesia and episiotomy. The current study has used GoM to identify the coexistence of the adopted obstetric interventions. Variables such as age, schooling, skin color, primigravida, place-of-delivery financing, number of prenatal consultations, gestational age at delivery, presence of obstetric nurse at delivery time, paid work and presence of companion during delivery were taken into consideration at the time to build patients' profile. RESULTS Results have highlighted two antagonistic obstetric profiles, namely: profile 1 comprised parturient women who were offered diet, freedom to move, use of partogram, using non-pharmacological methods for pain relief, giving birth in lying position, patients who were not subjected to Kristeller maneuver, episiotomy or amniotomy, women did not receive oxytocin infusion, and analgesia using. Profile 2, in its turn, comprised parturient women who were not offered diet, who were not allowed to have freedom to move, as well as who did not use the partograph or who were subjected to non-pharmacological methods for pain relief. They were subjected to enema, perineal shaving, Kristeller maneuver, amniotomy and oxytocin infusion. In addition, they underwent analgesia and episiotomy. This outcome emphasizes the persistence of an obstetric care model that is not based on scientific evidence. Based on the analysis of factors that influenced the coexistence of obstetric interventions, the presence of obstetric nurses in the healthcare practice has reduced the likelihood of parturient women to belong to profile 2. In addition, childbirth events that took place in public institutions have reduced the likelihood of parturient women to belong to profile 2. CONCLUSION(S) Based on the analysis of factors that influenced the coexistence of obstetric interventions, financing the hospital for childbirth has increased the likelihood of parturient women to belong to profile 2. However, the likelihood of parturient women to belong to profile 2 has decreased when hospitals had an active obstetric nurse at the delivery room. The current study has contributed to discussions about obstetric interventions, as well as to improve childbirth assistance models. In addition, it has emphasized the need of developing strategies focused on adherence to, and implementation of, assistance models based on scientific evidence.

Abstract
Human papillomavirus (HPV) infection and related diseases are common among men who have sex with men (MSM). The most effective prevention is HPV vaccination. In China, however, men are not included in the HPV vaccination plan. We investigated the intention to initiate HPV vaccination and associated factors among MSM in China. Methods We surveyed 563 unvaccinated MSM aged 18 or older from six cities in China. Participants completed an electronic questionnaire about demographics, knowledge of and attitude towards HPV and HPV vaccine, intention to initiate HPV vaccination, willingness to recommend HPV vaccine to peers, feeling about government policy about HPV vaccination. We used the structural equation modeling (SEM) to analyze factors associated with HPV vaccine intention. Results The knowledge of HPV and HPV vaccine among participants was low. The mean score of knowledge about HPV and HPV vaccine was only 1.59 (range 0–11). The intention to initiate HPV vaccination within 6 months among participants was moderate (43.3% in total, 18.1% for ‘very high' and 25.2% for ‘above average'). Low level of knowledge and intention to initiate HPV vaccination among MSM in China. Most variables of The Protection Motivation Theory were associated factors. Tailored intervention should be applied among MSM in China. Promotion of publicity and subsidization should be also considered.

Abstract
Men who have sex with men (MSM) are at risk of contracting the hepatitis C virus (HCV). Previous studies have documented low uptake of sexually transmitted disease (STD) prevention and health services among Chinese MSM. We carried out qualitative research among MSM in Southwest China. By taking the Health Brief Model (HBM) as a framework, we aimed to determine the underlying factors related to use of HCV health intervention services among MSM. From May to July 2018, we conducted in-depth interviews in Southwest China with 20 participants. Our research revealed that a lack of knowledge about HCV prevention was the main reason why MSM failed to perceive their susceptibility to HCV and had low motivation to seek preventive services. Poor service accessibility and unpleasant experiences seeing doctors also exerted negative influences on health care-seeking behaviour in MSM. More trust and understanding needs to be built between health providers and MSM. Protection of privacy for MSM should be guaranteed in the delivery of health interventions. In addition, the interviewees showed refusal to engage with health interventions being specifically targeted at MSM, which would create a sense of being 'labelled'. Tailored health interventions may overemphasise their sexuality, segregate them from heterosexuals, and make them feel alienated. Therefore, we speculate that differential treatment may be an obstacle for MSM to become involved in health interventions.

Abstract
Objective The Chinese men who have sex with men (MSM) population is suffering from a high HIV infection rate owing to unprotected anal sex. The Health Belief Model (HBM) has been proven to be an effective frame associated with behavior maintenance. Based on HBM, we analyzed the beliefs associated with consistent condom use behavior with regular and nonregular partners among MSM to better provide targeted interventions and services. Methods A study was conducted in Sichuan Province, China, from November 2018 to April 2019, and 801 eligible participants were recruited by snowball sampling. Sociodemographic characteristics, AIDS-related characteristics, sexual behaviors, condom use behavior, and dimensions of HBM were investigated. Univariate, single multivariate, and summary multivariate models were employed to analyze the factors associated with consistent condom use. Results Of all participants, 39.1% and 53.6% had had anal sex with regular and nonregular partners in the last six months, respectively. Only 56.5% of them had used condoms consistently with regular partners, and only 60% of them had used condoms consistently with nonregular partners. When taking consistent condoms use with regular partners as the dependent variable, the dimensions of perceived threats (ORM = 1.28, 95% CI: 1.10, 1.49), perceived barriers (ORM = 0.70, 95% CI: 0.60, 0.82), self-efficacy (ORM = 1.23, 95% CI: 1.14, 1.32), and cues to action (ORM = 1.21, 95% CI: 1.02, 1.43) showed significant associations with the dependent variable. When taking consistent condoms use with nonregular partners as the dependent variable, the dimensions of perceived barriers (ORM = 0.77, 95% CI: 0.67, 0.89), self-efficacy (ORM = 1.22, 95% CI: 1.13, 1.32), and cues to action (ORM = 1.53, 95% CI: 1.30, 1.80) showed significant associations with the dependent variable. Conclusions More attention should be focused on how to decrease the obstructive factors of condom use, how to improve the confidence of condom use, and how to layout more cues to action to promote consistent condom use behavior with regular and nonregular partners during anal sex among Chinese MSM.

Abstract
In mainland China, HIV prevalence among men who have sex with men (MSM) has risen sharply in the past decade. However, few HIV studies have directly addressed the female spouses' (tongqi) experiences, a population estimated at 14 million [Cheng, F. K. (2016). I want to come forward: Voices from Chinese tongqi. Cogent Social Sciences, 2(1), 1158343. doi:10.1080/23311886.2016.1158343; Zhu, J. (2018). "Unqueer" kinship? Critical reflections on "marriage fraud" in mainland China. Sexualities, 21(7), 1075-1091. doi:10.1177/1363460717719240]. We conducted this exploratory qualitative study to understand tongqi's attitudes toward same-sex sexuality and HIV risk as well as their sexual history. Semistructured interviews were conducted with 24 tongqi between October 2015 and September 2016. Data were coded and analyzed using thematic analysis. We identified four primary themes: (a) surprise, initial disbelief, and negative attitudes toward their husbands' same-sex sexuality; (b) maintenance of regular sexual contact, particularly before pregnancy; (c) unprotected sex with marital and extramarital partners; and (d) low perception of HIV risk. Strategies to increase HIV knowledge and testing uptake are urgently needed among these vulnerable women but must be implemented with caution to avoid exacerbating high levels of homophobia.

Consensus has been reached about the important role of partner notification (PN) for HIV prevention and control programs. We used a qualitative study to explore facilitators of and barriers to PN to understand reasons for disclosure and nondisclosure by people living with HIV in China. Our main goal was to identify information related to PN that may be unique to the Chinese cultural context. Of 41 participants who were interviewed, 33 had disclosed their HIV status to sexual partners. Facilitators for PN included preserving the integrity of the partnership, social support, and potential benefits of notification; barriers included perceived discrimination/stigma, possible negative consequences, and safety concerns. Participant physical health conditions, strength of the relationship, and concordant identification were found to be conditional factors of PN. Our findings provide information for a better understanding of PN in Chinese culture and offer a reference for developing more specific strategies to facilitate PN.

Abstract
PurposeThe purpose of this paper is to determine the effectiveness of a modified HBM-based intervention to reduce body mass index (BMI) for age in overweight junior high school students.Design/methodology/approachA cluster-randomized controlled trial was conducted in the first and second years of a junior high school in the center of Thailand. In total, 24 classrooms were randomly assigned to a modified health belief model intervention arm (HBMIA), and 24 classrooms were randomly assigned to a traditional school health education arm (control). In total, 479 students who were overweight (BMI forage = median +1 SD, aged 12–15 years) participated in the study. The HBMIA used the health belief model (HBM) as a motivator for behavioral strategies that included modifying diet and participating in physical activity. BMI, health knowledge and behavior for preventing obesity were recorded at baseline and at six months. A multilevel regression model was performed to calculate mean difference between HBMIA and control group.FindingsThe students who participated in the HBMIA showed a decrease in BMI of 1.76 kg/m2, while those who participated in the control showed an increase in BMI of 1.13 kg/m2, with a mean difference of –2.88 kg/m2(95% CI =–3.01 to –2.75), an improvement in health knowledge (mean difference 27.28; 95% CI =26.15–28.41) and an improvement in health behavior (mean difference 23.54; 95% CI =22.60–24.48).Originality/valueA modified HBM-based intervention to reduce BMI for age is effective in overweight junior high school students.

Abstract
Differences in sociodemographic variables, health beliefs, and a healthy lifestyle all contribute to the varied prevalence of metabolic syndrome (MetS). We investigated the associations among MetS-related risk factors and performed a cross-sectional study, recruiting 1741 Taiwanese residents aged ≥30 years, between August 2014 and August 2015. Data were obtained on sociodemographic factors, health beliefs, and health-promoting lifestyle profiles using questionnaires. Multivariate analysis revealed that age ≥65 years (odds ratio [OR] = 2.17), low educational level (OR = 1.46), body mass index ≥24 kg/m2 (OR = 9.00), more health responsibility (OR = 1.08), and less exercise (OR = 0.924) were independent risk factors for MetS development. A correlation existed between health beliefs and health-promoting lifestyle profiles, suggesting that the establishment of an effective health-promoting program should consider participants' health beliefs.

Abstract
Promoting HIV testing is an important strategy to end the HIV epidemic. HIV incidence among men who have sex with men (MSM) has increased rapidly in China in recent years, but HIV testing rates are still low. Our cross-sectional study investigated HIV testing rates and analyzed associated factors in 565 MSM in Changsha between April and December 2014. In the previous year, 37.7% of participants had not been tested, 38.2% had had one test, and 24.1% had had two or more tests. Those who initiated sexual debut at an older age, had known someone infected with HIV, or had been diagnosed with a sexually transmitted illness (STI) were more likely to have had an HIV test. HIV intervention programs in China should focus on sexually active young MSM, integrate HIV testing and counseling services in STI clinics, and describe real experiences of living with HIV to improve HIV testing in MSM.

Abstract
BACKGROUND HIV is one of the primary causes of death in Guatemala, and during the period 2005 to 2013, Guatemala exhibited a 95% increase in such deaths. HIV transmission rates are nearly 3 times higher among the indigenous Mayan population than nonindigenous Guatemalans. Guided by the community-based participatory research approach, this article demonstrates the iterative formative research process necessary to develop a deeper and more informed understanding of HIV prevention attitudes and behaviors in the priority population. This project extends preliminary formative research that demonstrated the applicability of the health belief model (HBM) in examining risk, stigma, and barriers and facilitators to condom use and HIV testing. METHOD Using an integrated mixed-method design, data were collected from heterosexual adults 18- to 25 years old ( N = 250), including 50 in-depth interviews and 200 rapid assessment surveys. RESULTS HBM concepts of risk and stigma were confirmed. Data also revealed low rates of condom negotiation and high embarrassment in purchasing and discussing condom use. Furthermore, data yielded very low uptake rates and reduced levels of comfort with getting tested. CONCLUSION This research informs refinement of a culture-specific intervention prioritizing indigenous Mayans. We highlight how community-based research and engagement enhance community health promotion.

Abstract
Background Mexico is one of the countries with the highest rates of overweight and obesity around the world, with 68.8% of men and 73% of women reporting both. This is a public health problem since there are several health related consequences of not exercising, like having cardiovascular diseases or some types of cancers. All of these problems can be prevented by promoting exercise, so it is important to evaluate models of health behaviors to achieve this goal. Among several models the Health Belief Model is one of the most studied models to promote health related behaviors. This study validates the first exercise scale based on the Health Belief Model (HBM) in Mexicans with the objective of studying and analyzing this model in Mexico. Methods Items for the scale called the Exercise Health Belief Model Scale (EHBMS) were developed by a health research team, then the items were applied to a sample of 746 participants, male and female, from five cities in Mexico. The factor structure of the items was analyzed with an exploratory factor analysis and the internal reliability with Cronbach’s alpha. Results The exploratory factor analysis reported the expected factor structure based in the HBM. The KMO index (0.92) and the Barlett’s sphericity test (p < 0.01) indicated an adequate and normally distributed sample. Items had adequate factor loadings, ranging from 0.31 to 0.92, and the internal consistencies of the factors were also acceptable, with alpha values ranging from 0.67 to 0.91. Conclusions The EHBMS is a validated scale that can be used to measure exercise based on the HBM in Mexican populations.

Effectiveness of a multimodal standard nursing program on health-related quality of life in Chinese mainland female patients with breast cancer: protocol for a single-blind cluster randomized controlled trial. BMC Cancer 2016; 16:698. [PMID: 27576298 PMCID: PMC5006518 DOI: 10.1186/s12885-016-2726-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2016] [Accepted: 08/16/2016] [Indexed: 11/23/2022] Open
Abstract
Background Breast cancer and its treatment-related adverse effects are harmful to physical, psychological, and social functioning, leading to health-related quality of life (HRQoL) impairment in patients. Many programs have been used with this population for HRQoL improvement; however, few studies have considered the physical, psychological, and social health domains comprehensively, and few have constructed multimodal standard nursing interventions based on specific theories. The purpose of this trial is to examine the effect of a health belief model (HBM)-based multimodal standard nursing program (MSNP) on HRQoL in female patients with breast cancer. Methods This is a two-arm single-blind cluster randomized controlled trial (cRCT) in clinical settings. Twelve tertiary hospitals will be randomly selected from the 24 tertiary hospitals in Xi’an, China, and allocated to the intervention arm and control arm using a computer-generated random numbers table. Inpatient female patients with breast cancer from each hospital will receive either MSNP plus routine nursing care immediately after recruitment (intervention arm), or only routine nursing care (control arm). The intervention will be conducted by trained nurses for 12 months. All recruited female patients with breast cancer, participating clinical staff, and trained data collectors from the 12 hospitals will be blind with respect to group allocation. Patients of the control arm will not be offered any information about the MSNP during the study period to prevent bias. The primary outcome is HRQoL measured through the Functional Assessment of Cancer Therapy-Breast version 4.0 at 12 months. Secondary outcomes include pain, fatigue, sleep, breast cancer-related lymphedema, and upper limb function, which are evaluated by a visual analogue scale, the circumference method, and the Constant-Murley Score. Discussion This trial will provide important evidence on the effectiveness of multimodal nursing interventions delivered by nurses in clinical settings. Study findings will inform strategies for scaling up comprehensive standard intervention programs on health management in the population of female patients with breast cancer.
