Active Compared With Passive Voiding Trials After Midurethral Sling Surgery: A Systematic Review

OBJECTIVE

To compare active with passive voiding trials on the rate of passing a trial of void and discharge rates with catheter in women who have undergone midurethral sling for treatment of stress urinary incontinence (SUI).

DATA SOURCES

MEDLINE, EMBASE, and ClinicalTrials.gov were searched through February 24, 2023.

METHODS OF STUDY SELECTION

Our population included women undergoing midurethral sling, with or without anterior or posterior repair, for treatment of SUI. Our two primary outcomes were rate of passing voiding trial and rate of discharge with a catheter. Our secondary outcome was the rate of delayed postoperative urinary retention, when a patient initially passes a trial of void but then subsequently presents in retention.

TABULATION, INTEGRATION, AND RESULTS

Abstracts were doubly screened; full-text articles were doubly screened; and accepted articles were doubly extracted. In single-arm studies evaluating either passive or active voiding trial, random-effects meta-analyses of pooled proportions were used to assess outcomes. Of 3,033 abstracts screened, 238 full-text articles were assessed, and 26 met inclusion criteria. Ten studies including 1,370 patients reported active trial of void. Sixteen studies including 3,643 patients reported passive trial of void. We included five randomized controlled trials, five comparative retrospective studies, five prospective single group studies, and 11 retrospective single group studies. Five of the studies included patients with a concomitant anterior or posterior colporrhaphy. On proportional meta-analysis, the active trial of void group was less likely to pass the voiding trial (81.0%, 95% CI, 0.76-0.87% vs 89.0%, 95% CI, 0.84-0.9%3, P =.029) with high heterogeneity ( I2 =93.0%). Furthermore, there were more discharges with catheter in active trial of void compared with passive trial of void (19.0%, 95% CI, 0.14-0.24% vs 7.0%, 95% CI, 0.05-0.10%, P <.01). The rates of delayed postoperative urinary retention were low and not different between groups (0.6%, 95% CI, 0.00-0.02% vs 0.2%, 95% CI, 0.00-0.01%, P =.366) with low heterogeneity ( I2 =0%). Sling revisions were statistically lower in the active trial of void group (0.5%, 95% CI, 0.00-0.01% vs 1.5%, 95% CI, 0.01-0.02%, P =.035) with low heterogeneity ( I2 =10.4%).

CONCLUSION

Passive trial of void had higher passing rates and lower discharge with catheter than active trial of void. Rates of most complications were low and similar between both groups, although passive trial of void had higher sling revisions.

A Review of the Past, Present, and Future of the Monkeypox Virus: Challenges, Opportunities, and Lessons from COVID-19 for Global Health Security

Monkeypox, a rare but significant zoonotic and orthopoxviral disease, has garnered increasing attention due to its potential for human-to-human transmission and its recent resurgence in multiple countries throughout Europe, North America, and Oceania. The disease has emerged as a novel threat to the global health systems that are still striving to recover from the major shocks of the COVID-19 pandemic. The unusual manifestation of the illness highlights a substantial knowledge deficit and necessitates the immediate development of a public health action strategy, considering the epidemiological differences observed in the ongoing outbreak and the appearance of cases in non-endemic nations. This literature review aims to synthesize existing knowledge on monkeypox, encompassing its historical context, etiology, epidemiology, surveillance, prevention, transmission, clinical presentation, diagnosis, treatments, and recent outbreak. Particular attention is given to both advances and gaps in our understanding of monkeypox, and we point toward future directions for research and intervention efforts as pertains to vaccine development and distribution. Lastly, we will also review the recent outbreak through a sociopolitical lens as relates to decision-making strategies, especially given the lessons learned from COVID-19.

Review of Endometrial Receptivity Array: A Personalized Approach to Embryo Transfer and Its Clinical Applications

Successful outcomes of in vitro fertilization (IVF) rely on both the formation of a chromosomally normal embryo and its implantation in a receptive endometrium. Pre-implantation genetic testing for aneuploidy (PGT-A) has been widely accepted as a tool to assess the viability of an embryo. In 2011, the endometrial receptivity array (ERA) was first published as a tool to determine when the endometrium is most receptive to an embryo, commonly referred to as the "window of implantation" (WOI). The ERA uses molecular arrays to assess proliferation and differentiation in the endometrium and screens for inflammatory markers. Unlike PGT-A, there has been dissent within the field concerning the efficacy of the ERA. Many studies that contest the success of the ERA found that it did not improve pregnancy outcomes in patients with an already-good prognosis. Alternatively, studies that utilized the ERA in patients with repeated implantation failure (RIF) and transfer of known euploid embryos demonstrated improved outcomes. This review aims to describe the ERA as a novel technique, review the various settings that the ERA may be used in, such as natural frozen embryo transfer (nFET) and hormone replacement therapy frozen embryo transfer (HRT-FET), and provide a summary of the recent clinical data for embryo transfers in patients with RIF utilizing the ERA.

Impact of COVID-19 on the essential healthcare services at primary healthcare level

Background

The COVID-19 pandemic triggered numerous challenges for the healthcare systems worldwide, particularly affecting the continuity of essential health services in low- and middle-income countries. We explored the effects of the COVID-19 pandemic on the utilization and delivery of essential health services in Armenia.

Methods

We applied a conventional qualitative study design using semi-structured in-depth interviews (n = 17) in public and private primary healthcare (PHC) facilities in Armenia (2021). Participants included physicians providing primary health services (e.g. endocrinologists, gynecologists/obstetricians, and pediatricians), regular PHC facility patients (e.g. adults with chronic diseases, parents of children), and policymakers. Iterative thematic analysis was done based on inductively emerged 3 main themes: patient-provider communications, maternal and child health services, and management of chronic diseases.

Results

Overall, visits to the PHC facilities were decreased due to fear to contract COVID-19 coupled with lack of information, misinformation and panic. There was a lack of digital platforms for ensuring continuous patient-provider communication and phone calls were the main way of communication. PHC providers intentionally limited the number of maternal and child visits to only essential antenatal visits, newborn screenings and routine child immunizations. Still, the latter has suffered resulting in delayed and decreased vaccinations. The pandemic remarkably decreased the number of follow-up visits and monitoring of patients with chronic conditions resulting in more critical and severe conditions.

Conclusions

The COVID-19 pandemic affected the provision and utilization of essential health services at PHC facilities by changing people’s health-seeking behavior. Unified national-level guidance for PHC facilities is needed to direct the provision of essential services, effective health communication and usage of digital platforms.

Key messages

• Though provider encounters should be limited during outbreaks, continuous provision of essential services is critical in the prevention of morbidity, complications and worsened disease severity.

• Efforts are needed to develop effective health and risk communication strategies and enhance appropriate usage of digital platforms to promote adequate health-seeking behavior among the public.

Predictors of seropositivity against SARS-COV-2: a population-based seroepidemiological study

Background

Data on parameters of actual exposure to SARS-CoV-2 is limited, and specific population groups might be at a higher risk of infection. In line with the growing need for large-scale investigations to determine the presence of antibodies against SARS-CoV-2 among different population groups, we conducted a nationwide assessment in Armenia.

Methods

We performed a cross-sectional seroepidemiological study among the adult population in Armenia, in May-September 2021. A multi-stage cluster random sampling was performed to recruit the participants across the capital city and regions. The study had two main components: blood sampling, which took place in primary care facilities and a phone survey on socio-demographic characteristics, comorbidities, and previous history of COVID-19.

Results

The number of participants included in both blood sampling and phone survey was 3483. The nationwide prevalence of SARS-CoV 2 antibodies weighted by age and gender was 66.4% with significantly higher prevalence in urban compared to rural areas (67.3% vs 59.3%, p &lt; 0.001). Only 22.7% (n = 772) of the total sample reported a previous history of PCR confirmed COVID-19, among whom antibodies were detected in 94.2% (n = 727). In the final adjusted model, the seropositivity was associated with being female (OR = 1.60, 95% CI: 1.32; 1.92), employed (OR = 1.41, 95% CI: 1.17; 1.69), and having previous PCR confirmed COVID-19 (OR = 10.6, 95% CI: 7.39; 15.21).

Conclusions

Over 66% of the population were seropositive for antibodies against SARS-CoV 2; and over ⅕ of the sample reported a previous PCR diagnosis. Factors associated with increased odds of seropositivity included gender, employment status, and place of residence. Targeted interventions are recommended to minimize the risk of infection among those groups, including vaccination and infection prevention and control measures.

Key messages

• The prevalence of SARS-CoV 2 antibodies is about three times higher than the rate of infection based on PCR confirmed prevalence of COVID-19.

• Women, people living in urban areas, and those employed are at a higher risk for exposure to SARS-CoV 2.

The impact of smoking on immunological response to SARS-COV 2: a nationwide seroepidemiological study

Background

Smoking influences cellular and humoral immune responses and affects the immune system by increasing inflammation and decreasing activity against infections. The current study investigates the association between smoking and immunological response to SARS-CoV-2 in the Armenian population.

Methods

We performed a nationwide cross-sectional seroepidemiological study among the adult population (≥18 years old) in Armenia. We used a multi-stage cluster random sampling to recruit participants from the capital city and all regions of Armenia. We invited selected participants to primary healthcare facilities to provide blood samples for antibody testing followed by a phone survey on demographic characteristics, smoking status, and other variables. Logistic regression analysis was used to test the relationship between smoking and having SARS-CoV-2 antibodies adjusted for other covariates.

Results

3483 people participated in the study (71% women). The total sample included 16.8% current smokers (n = 571), 8.6% past smokers (n = 294) and 76.4% never smokers (n = 2538). The prevalence of SARS CoV-2 antibodies among current smokers was statistically significantly lower as compared with never smokers (46.9% vs 73.4%, p-value&lt;0.001). In the multivariable logistic regression model, the odds of having SARS CoV-2 antibodies among the current smokers was 70% lower (OR 0.30, 95%CI: 0.22; 0.40) compared to never smokers, when adjusted for demographic factors and the time of PCR diagnosis of COVID-19. No statistically significant difference was found between past smokers and having SARS CoV-2 antibodies.

Conclusions

In addition to being a risk factor for various chronic diseases, smoking weakens immune response to infectious diseases, including COVID-19, worsening the outcomes. The significantly lower level of antibody prevalence among smokers with previous PCR confirmed COVID 19 implies a poorer immune response to the infection and not a lower risk of getting the infection.

Key messages

• Smoking weakens immune response and contributes to a higher burden of infectious diseases, such as COVID-19.

• Lower level of antibody prevalence among smokers indicates a poorer immune response to the infection rather than a lower risk of getting the infection.

Moving towards people–centered approach in TB Health Care System: Armenia’s Experience

Background

Achieving integrated people-centered care requires interventions at various levels of the system, including policy changes and measures tailored to strengthen skills and competencies of health care providers. The national guidelines for TB care provision in Armenia provide a standardized approach for TB diagnosis and treatment, including systematic implementation of TB care services across the country. Before August 2019, the only option for drug-sensitive TB treatment was facility-based DOT.

Methods

In order to offer an alternative treatment option- family- based DOT, and bring TB services closer to patients' needs and values, the national guideline for TB care provision was updated to institutionalize the new approach. A series of nationwide professional development trainings was launched to assure that health care providers at the inpatient and outpatient settings effectively follow the new updates in the national guideline. These evidence-based trainings specifically aimed to equip healthcare providers with the necessary tools, knowledge, and the skillset for communicating with TB patients and building relationship and trust, offering their professional support. Along with patient counselling skills, the curriculum covered recent updates on TB epidemic, its social-psychological and behavioral risk factors, and advancements in TB diagnosis and treatment. All the participants were provided with a manual and other materials regarding the program.

Results

The Ministry of Health of the RA has approved the national guidelines on TB care (No 2277 - Ô±, August 19). This document includes information on people-centered TB treatment and institutionalizes the family-based DOT in Armenia. More than 90 percent of TB healthcare providers (98 physicians and 134 nurses) throughout Armenia participated in the trainings and received certificates. The RA Ministry of Health accredited the training curriculum with 11 continuing medical education credits for participation.

Integrating psycho–social counselling in TB Services in Armenia

Background

Community or family-based DOT improves clinical outcomes and quality of life of TB patients compared to facility-based DOT. Based on a previously conducted clinical trial and recommended best practice guidelines, Armenia started the institutionalization of the family-based DOT in 2019, as an important component of the integrated people-centered approach in TB treatment. Psycho-social counselling and education played a crucial role in preparing patients/family members for this new model of care.

Methods

To facilitate the family-based DOT, multidisciplinary counseling teams consisting of a TB nurse and a psychologist or a TB nurse and a social worker were formed and further incorporated into the existing TB care system. After a systematic evaluation the strongest applicants were shortlisted, interviewed, and selected. They underwent a three-day training, improving their knowledge on TB disease, its transmission, diagnosis and treatment; patient counseling with an emphasis on motivational interviewing techniques; and people-centered TB care. A comprehensive package of procedural documents was developed to facilitate the counseling teams work process, including a guideline on counseling, reporting forms, and patients' educational materials. At an early stage of TB treatment, the counseling teams provide psycho-social counselling to patients and their families, and educate them on TB risk factors and infection control.

Results

The counselling teams have been based in the National Center of Pulmonology of the RA and provide psycho-social counselling to all drug susceptible TB patients and their family members all over Armenia. The counseling teams prepare patients/family members for the family-based DOT and provide continuous support during the entire treatment. The integration of counselling teams in the TB care system has provided the required human resource and capacity for the successful adoption of a new model of people-centered TB care in Armenia.

Barriers to reproductive health services utilization among adolescents

Background

Adolescents' access to quality reproductive health services is crucial for their psychosocial and physical wellbeing. Yet, adolescents encounter various barriers while utilizing reproductive health services, globally. Adolescent-friendly health services (AFHS) is an evidence-based intervention to meet the reproductive health needs inclusively of all adolescents. The study aimed to explore adolescents' experiences while seeking reproductive health services in primary healthcare facilities (PHCF) in Armenia.

Methods

We conducted a qualitative cross-sectional study using in-depth interviews, focus group discussions and observations of PHCFs. The study participants included adolescents (aged 18-19 years) (n = 17), PHC providers (PHP) (n = 29), managers of PHCFs (n = 7) and experts in the field of adolescent health (n = 5) from the two largest cities in Armenia. The Global standards for quality healthcare services for adolescents guided the instrument development process and deductive content analysis.

Results

Barriers to the utilization of reproductive health services by adolescents at PHCFs were related to various personal, cultural, and social factors. PHPs and experts blamed adolescents' insufficient knowledge of reproductive health and related services for being a major barrier. However, adolescents' reported a different set of important barriers to reproductive health services: PHPs' judgmental attitude, lack of efforts to protect privacy and confidentiality (due to lack of PHP competencies to provide AFHS and inadequate PHCF infrastructure), negative public opinion and lack of community support.

Conclusions

The study findings shed light on different perspectives related to various challenges adolescents come across in PHCFs. Addressing identified barriers have the potential of positively influencing adolescents' experiences while utilizing reproductive health services in PHCFs.

Key messages

Adolescents’ insufficient knowledge, PHPs’ judgmental attitude, lack of privacy and confidentiality, and negative public opinion are among the main barriers to the reproductive health services. Further enforcement of adolescent-friendly health services in primary healthcare facilities is needed to ensure accessibility of quality reproductive health services for all adolescents.

Gender differences in perceived stress level among undergraduate students in Armenia

Background

Stress is an important issue in academic institutions and can have a negative impact on overall academic performance. This study was conducted as a research assignment during the Basics of Healthy Lifestyle course and aimed to investigate the stress level among undergraduate students at the American University of Armenia (AUA).

Methods

A cross-sectional survey was conducted among undergraduate students recruited by non-random convenience sampling. The study utilized a structured questionnaire to conduct face to face interviews. The questionnaire contained 40 close-ended questions on students' perceived stress level, the Student Stress Scale (SSS) (sum of scores of 31 questions) to measure actual stress, and socio-demographic characteristics. Data entry, descriptive and comparative statistics were performed using SPSS software. Secondary data analysis was conducted to explore gender differences in stress level.

Results

Overall, 111 AUA students participated and slightly over half of participants (59.5%) were female. The SSS revealed that 46.0% of students experience medium stress levels (self-perceived mean stress score =-5.8). Only 21.6% perceived themselves as having high stress levels; however, SSS showed that about one third had high stress. Female participants' perception of being highly stressed and having high stress level based on SSS were similar (28.8% and 27.3%, respectively). In contrast, less males perceived being highly stressed (13.3%), though, SSS showed that 40.0% of males experienced high stress levels.

Conclusions

The majority of AUA undergraduate students experienced medium or low stress levels. Male students experience higher stress levels, but their perceived stress level was much lower than in among females. Research is needed to explore the gender differences in stress levels and coping mechanisms among students. These findings may be useful for university administration for developing stress-reduction and stress-management strategies.

Key messages

There are disparities in perceived stress and actual stress levels between male and female students that warrant further exploration. Gender differences in stress level of the students should be considered for stress-reduction and stress-management strategies.

Compliance with smoke-free policy at tuberculosis facilities in Armenia: a mixed-methods study

Background

Smoke-free environments in tuberculosis (TB) facilities promote a tobacco-free lifestyle among patients and healthcare providers and advance their healthy image. Though the national law of Armenia prohibits indoor smoking in healthcare facilities, enforcement of the law is still insufficient. This study aimed to explore compliance with the smoke-free policy in TB facilities in Armenia.

Methods

An exploratory sequential mixed-methods study was conducted. Overall 21 TB physicians and five key informants in the field of TB and tobacco control participated in qualitative interviews. To further quantify and validate the findings, structured observations of smoke-free policy implementation were conducted in 36 facilities.

Results

All physicians expressed a positive attitude towards the smoke-free environment and were satisfied with the level of implementation of a smoke-free policy in their TB facilities. According to the respondents, they already have smoke-free environments established in their facilities. “No smoking” signs, warnings about health consequences and financial penalties, and pictures of damaged lungs were the most common measures against indoor smoking. However, only in 17.1% (n = 6) and 8.6% (n = 3) of observed TB facilities there were posted “No smoking” signs and financial penalties, respectively. In 5.7% (n = 2) of facilities, the research team found ashtrays inside the building, and in 20.0% (n = 7) of facilities, there were smoking patients, physicians, and visitors.

Conclusions

While the qualitative study indicated good compliance, the quantitative findings were controversial with this regard. In fact, in most of the facilities, the smoke-free policy was not properly implemented and enforced. Additional efforts are needed to harmonize the current practices with national policies and recommendations.

Key messages

There was a discrepancy between practices reported by physicians and the actual observed compliance. Further interventions are needed to ensure 100% compliance with smoke-free policy in TB healthcare facilities.

Broadband near-infrared astronomical spectrometer calibration and on-sky validation with an electro-optic laser frequency comb

The quest for extrasolar planets and their characterization as well as studies of fundamental physics on cosmological scales rely on capabilities of high-resolution astronomical spectroscopy. A central requirement is a precise wavelength calibration of astronomical spectrographs allowing for extraction of subtle wavelength shifts from the spectra of stars and quasars. Here, we present an all-fiber, 400 nm wide near-infrared frequency comb based on electro-optic modulation with 14.5 GHz comb line spacing. Tests on the high-resolution, near-infrared spectrometer GIANO-B show a photon-noise limited calibration precision of < 10 cms as required for Earth-like planet detection. Moreover, the presented comb provides detailed insight into particularities of the spectrograph such as detector inhomogeneities and differential spectrograph drifts. The system is validated in on-sky observations of a radial velocity standard star (HD221354) and telluric atmospheric absorption features. The advantages of the system include simplicity, robustness and turn-key operation, features that are valuable at the observation sites.

Large Cryogenic Storage of Hydrogen in Carbon Nanotubes at Low Pressures

We report (6 wt %) storage of H2 at T=77 K in processed bundles of single-walled carbon nanotubes at P=2 atmospheres. The hydrogen storage isotherms are completely reversible. D2 isotherms confirm this anomalous low-pressure adsorption and further reveal the effects of quantum mechanical zero point motion. We propose that our post-synthesis treatment of the sample not only improves access for hydrogen to the central pores within individual nanotubes, but also may create a roughened tube surface with an enhanced binding energy for hydrogen. Such an enhancement is needed to understand the strong adsorption at low pressure. We obtain an experimental isosteric heat qst=125 ± 5 meV for processed SWNT materials.

[Comparative evaluation of indicators of local, humoral immunity and nonspecific resistance in patients with different pathology of the cervix]

A comparative evaluation of some indicators of immune system and analysis of the dependence of these parameters (correlation) are carried out to identify interrelated mechanisms. The observed changes in the concentrations of indicators of immune system and the correlation between cytokines, humoral immunity and nonspecific resistance in cervical mucus in patients with cervical pathology demonstrate the complex, interrelated and changing interactions of the local immune system at various stages of development of the pathological process of the cervix.

Midrapidity antiproton-to-proton ratio in pp collisons at sqrt[s]=0.9 and 7 TeV measured by the ALICE experiment

The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at sqrt[s]=0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers the transverse momentum interval 0.45<p_{t}<1.05  GeV/c and rapidity |y|<0.5. The ratio is measured to be R_{|y|<0.5}=0.957±0.006(stat)±0.014(syst) at 0.9 TeV and R_{|y|<0.5}=0.991±0.005(stat)±0.014(syst) at 7 TeV and it is independent of both rapidity and transverse momentum. The results are consistent with the conventional model of baryon-number transport and set stringent limits on any additional contributions to baryon-number transfer over very large rapidity intervals in pp collisions.

Patrilocality and recent migrations have little impact on shaping patterns of genetic structure of the Armenian population

In general, genetic distances between human populations (also within one ethnic group) are larger for the Y chromosome markers than for the mtDNA. It is usually explained by higher rate of female versus male migration due to the cultural practice of patrilocality, when women move to their husbands' residence after marriage. Recently found a reversed picture for the genetic variation in some ethno-territorial groups confirm the strict role of cultural traditions in shaping patterns of populations' genetic structure. To test the role of patrilocality for the genetic structure of the Armenian population, we compared the Y chromosome and the mtDNA haplotype variations among and between geographical groups identified according to paternal (maternal) grandparental place of birth, from one side, and the populations currently living in the same geographical areas, from the other side. The results demonstrate that the Armenian population is regionally more structured for the Y chromosome than for the mtDNA. Additionally, in spite of expressed directivity of migration processes (caused by the phenomenon of patrilocality as well), the patterns of genetic variations for the populations of the same geographic areas remain without any significant changes during the last three generations.

A giant outburst two years before the core-collapse of a massive star

The death of massive stars produces a variety of supernovae, which are linked to the structure of the exploding stars. The detection of several precursor stars of type II supernovae has been reported (see, for example, ref. 3), but we do not yet have direct information on the progenitors of the hydrogen-deficient type Ib and Ic supernovae. Here we report that the peculiar type Ib supernova SN 2006jc is spatially coincident with a bright optical transient that occurred in 2004. Spectroscopic and photometric monitoring of the supernova leads us to suggest that the progenitor was a carbon-oxygen Wolf-Rayet star embedded within a helium-rich circumstellar medium. There are different possible explanations for this pre-explosion transient. It appears similar to the giant outbursts of luminous blue variable stars (LBVs) of 60-100 solar masses, but the progenitor of SN 2006jc was helium- and hydrogen-deficient (unlike LBVs). An LBV-like outburst of a Wolf-Rayet star could be invoked, but this would be the first observational evidence of such a phenomenon. Alternatively, a massive binary system composed of an LBV that erupted in 2004, and a Wolf-Rayet star exploding as SN 2006jc, could explain the observations.
