Use of Resonant Acoustic Mixing Technology for Ultra-Low-Dose Blending in a Single-Step Mixing Process.

PURPOSE: To evaluate the use of resonant acoustic mixing (RAM) technology for homogenous blending of a morphologically challenging model API in low-dose concentrations (<0.1% w/w), and assess the potential for blend uniformity (BU) optimization. METHODS: Caffeine (CAF) mixing was carried out using a LabRAM I benchtop mixer. Uniformity was assessed under a range of mixing conditions and sample preparation procedures in order to optimize system performance. The capacity for microscale mixing was evaluated from final parameters for 0.05% and 0.0125% CAF blends. RESULTS: Upon optimization, RAM was able to accurately prepare homogeneous mixtures of <0.1% CAF in dilutions of up to 1 part per 8,000. Results from a 0.05% blend targeting 125 µg CAF dosage amounts revealed an AV score of 8.8 while a 0.0125% w/w blend accurately prepared 25 µg of CAF with 99.3% accuracy (98.7% label claim) and AV of 10.1. Microscale mixing in the 0.05% w/w blend was confirmed from plots of BU data against sample size demonstrating a slope of 0.05 within the range of 250-10 mg sample (125-5 µg CAF). L1 BU criteria only failed at the level of 2 µg CAF, despite target precision to 26 nanograms (98.7% label claim). CONCLUSIONS: This study presents the first instance of a homogenously mixed <0.1% (w/w) blend using RAM technology and demonstrate the suitability for reproducible dosing of single-digit microgram drug amounts. Uniformity is documented for API amounts 60x smaller than a recent report has shown and 10,000x smaller than achieved previously with CAF.

Opioid-involved overdose trainings delivered using remote learning modalities.

AIM: This education-focused study examined changes in nursing students' knowledge and attitudes towards responding to opioid-involved overdoses following participation in trainings delivered using remote learning modalities. DESIGN: This pre-post study examined learning outcomes among 17 nursing students. METHODS: Participants completed the Opioid Overdose Attitude Scale and Opioid Overdose Knowledge Scale to assess attitudes and knowledge, respectively. Trainings were delivered to two separate groups, one via virtual reality immersive video and another over video conferencing. RESULTS: Attitude scores increased by an average of 12.2 points and knowledge scores increased by 1.65 points. Within the virtual reality group, attitude scores increased by an average of 10 points, while no significant changes were observed in knowledge scores. The video conferencing group improved in both attitude and knowledge scores, by an average of 16.2 points and 2.1 points, respectively. CONCLUSIONS: These hypothesis generating results illustrate the utility of remote learning approaches to deliver trainings, while maintaining social distance during the ongoing COVID-19 pandemic.

Immediate sequential bilateral cataract surgery: patient perceptions and preferences.

BACKGROUND: Recent national data suggests that less than 0.5% of NHS cataract patients undergo immediate sequential bilateral cataract surgery (ISBCS). Since ISBCS improves service efficiency, increasing its practice may help tackle the ever-growing burden of cataract in the UK, and reduce the COVID-19 cataract backlog. Surgeon attitudes are known to be a significant barrier to increasing the practice of ISBCS. However, little is known about patient perceptions of ISBCS. METHODS: Patients at cataract clinics across three NHS hospital sites were recruited to complete an investigator-led structured questionnaire. Open-ended and closed-ended questions were used to assess awareness of ISBCS, willingness to undergo ISBCS and attitudes towards ISBCS. RESULTS: Questionnaires were completed by 183 patients. Mean participant age was 70.5 (9.9) years and 58% were female. Forty-three percent were aware of ISBCS, chiefly via clinic staff. Just over a third would choose ISBCS if given the choice, and participants that perceived they were recommended ISBCS were more likely to opt for it. The most common motivator and barrier to uptake of ISBCS was convenience and the perceived risk of complications in both eyes respectively. Concerns related to the recovery period were common, including misunderstandings, such as the need to wear eye patches that obscure both eyes. CONCLUSIONS: Our study indicates that significantly more NHS patients would be willing to undergo ISBCS if given the choice. The reluctance of surgeons to recommend ISBCS and patient misunderstandings regarding the recovery period may be limiting its uptake.

Factors associated with postpartum contraception in Togo, West Africa.

The health benefits of postpartum contraception are well established. Using 2013/14 Togo Demographic and Health Survey (DHS) data, we examine the association between contraceptive use among women who gave birth within 24 months of the DHS and four health service use indicators - antenatal care, institutional delivery, postpartum care, and immunization of the last child - in addition to socio-demographic factors. Factors associated with postpartum contraceptive use in Togo included having their last birth in a health facility, having a postnatal check within two months of birth, youngest child receiving the first diphtheria-pertussis-tetanus vaccine, wanting to space children more than two years from last birth or not have more children, living outside the Savanes region, husband's desire for number of children agreeing with the woman's, and increasing breastfeeding duration. These findings highlight the need for programming which strengthens the integration of contraception into reproductive and immunization services in Togo.

Palliative and End-of-Life Care Self-perceived Educational Needs of Physicians and Nurses in Rwanda.

Palliative care access is an urgent and ethical imperative to effectively manage the increasing burden of serious health-related suffering worldwide. Understanding the palliative care educational needs of health care professionals is critical to support evidence-based clinical practice in Rwanda and other low- and middle-income countries. A cross-sectional study was conducted at 5 hospitals in Kigali, Rwanda, to assess the palliative/end-of-life educational needs of nurses and physicians. The End-of-Life Professional Caregiver Survey and a demographic form were used to collect data. Descriptive analyses and independent t tests were conducted. A total of 420 health care professionals participated in the study (response rate, 72%). Participants perceived their knowledge and skills in providing palliative/end-of-life care as low. Those who received palliative/end-of-life care training in the past 5 years, third- and fourth-year residents, and health care providers with 5 years of experience or more had significantly higher (P ≤ .05) mean scores on the End-of-Life Professional Caregiver Survey. Nurses scored higher than physicians in the patient- and family-centered communication (P = .049) and cultural and ethical values (P = .037) subscales. Pain management was identified as an educational need by 77% of participants. Our survey suggests the need for increased governmental investments in palliative/end-of-life care education among nurses and physicians in Rwanda.

The Role of Nurses and Midwives in Expanding and Sustaining Voluntary Medical Male Circumcision Services for HIV Prevention: A Systematic and Policy Review.

ABSTRACT: Male circumcision reduces men's risk of acquiring HIV through heterosexual sex, and voluntary medical male circumcision (VMMC) is central to HIV prevention strategies in 15 sub-Saharan African countries. Nurses have emerged as primary VMMC providers; however, barriers remain to institutionalizing nurse-led VMMC. Patient safety concerns have hindered task sharing, and regulations governing nurse-performed VMMC are not always supportive or clear. We performed a systematic review on VMMC safety by provider cadre and a desk review of national policies governing the VMMC roles of nurses and midwives. Also, VMMC by nurses is safe and has become standard practice. Countries had multiple policy combinations among different documents, with only one disallowing VMMC by these cadres. Countries with alignment between policies often ensured that nursing workforces were equipped with clinical competencies through national certification. Regulatory clarity and formalized certification for nurse-performed VMMC can increase program sustainability and build nursing capacity to meet other critical basic surgical needs.

The cost and quality of life impact of glaucoma in Tanzania: An observational study.

AIMS: To determine the cost and quality of life impact imposed by glaucoma in Tanzania, East Africa. METHODS: An expert panel of eye health professionals was convened to agree current glaucoma practice in Tanzania. In addition a structured patient survey was developed and administered. Supplemental cost and quality of life information was collected using cost questionnaires and validated quality of life measures, including the EQ5D and VFQ-25. RESULTS: Key findings include following. Non-adherence is a major issue, especially in rural settings where over 50% of the patients may fail to return for review. Whilst medical therapy is overwhelmingly the first line treatment, the cost of maintaining this represents up to 25% of a patient's income. There is an impact of glaucoma on patients general well-being as determined by the EQ-5D and more tellingly on visual function with particular impact on role limitations as determined by the VF25. Despite our sample being taken in a private clinic and thus containing a much larger proportion of professionals than the general population, one third of the population earned Tanzanian Shillings (TZS) 170,000 per month which is below the minimum wage. CONCLUSION: These findings are of great importance for health care planners seeking to determine cost-effective, acceptable methods of both identifying and treating this major cause of preventable blindness.

Adherence with Medical Therapy for Primary Open-Angle Glaucoma in Kenya - A Pilot Study.

BACKGROUND/OBJECTIVES: Adherence is a major challenge in topical glaucoma therapy, particularly in an African context. We report a pilot study assessing adherence independently for the first time in an African context. SUBJECTS/METHODS: Participants with newly diagnosed open-angle glaucoma received a weighed bottle of Lumigan 0.01% with counselling on therapy. The bottles were returned monthly for renewal and weighed on return to estimate drops taken during the period. Data collection was for one year with a short compliance questionnaire. RESULTS: 11 patients participated. 5 (45%) failed to complete one full year of topical therapy. The overall mean number of drops per eye per day was 1.74 (SD 0.69) for the 6 with one year of monthly returned bottles and controlled IOPs at each visit. Self-perception of compliance in these patients was good. CONCLUSION: The signs of poor adherence based on both self-report (previous literature), and in this small-scale study of an objective measure suggest medication may not be the first-line treatment of choice in this environment. Our report does, however, raise the possibility that those patients who return for repeat prescriptions and review are indeed adhering to their treatment regimens.

Building Empathy and Professional Skills in Global Health Nursing Through Theatre Monologues.

BACKGROUND: As part of a global health professional development class, the authors designed an educational activity for nursing students to write and perform 5-minute monologues based on interviews with individuals involved in global health. The goals of this educational activity included developing empathy, teaching qualitative research methods, and strengthening writing and presentation skills while encouraging students to engage with global health practitioners and real-world global health recipients. METHOD: Groups of four to five students used information from interviews with key informants working or receiving care in the global health context to develop monologues with the assistance of theatre professionals. Students presented the monologues at the end of the semester. RESULTS: Student self-report and feedback from key informants indicated success in fulfilling the learning objectives. CONCLUSION: The innovative use of a monologue-based theatre component in an academic course increased empathy in undergraduate nursing students. [J Nurs Educ. 2019;58(11):653-656.].

' It is a question of determination': a case study of monitoring and evaluation of integrated family planning services in urban areas of Togo.

Background: Integrating family planning into postabortion and postpartum services can increase contraceptive use and decrease maternal and child death; however, little information exists on the monitoring and evaluation of such programs. This article draws on research completed by the EngenderHealth's AgirPF project in three urban areas of Togo on the extent to which monitoring and evaluation systems of health services, which operated within the AgirPF project area in Togo, captured integrated family planning services. Methods: This mixed methods case study used 25 health facility assessments with health service record review in hospitals, large community clinics, a dispensary, and private clinics and 41 key informant interviews with health faculty, individuals working at reproductive health organizations, individuals involved in reproductive health policy and politics, health care workers, and health facility directors. Results: The study found the reporting system for health care was labor intensive and involved multiple steps for health care workers. The system lacked a standardized method to record family planning services as part of other health care at the patient level, yet the Ministry of Health required integrated family planning services to be reported on district and partner organization reporting forms. Key informants suggested improving the system by using computer-based monitoring, streamlining the reporting process to include all necessary information at the patient level, and standardizing what information is needed for the Ministry of Health and partner organizations. Conclusion: Future research should focus on assessing the best methods for recording integrated health services and task shifting of reporting. Recommendations for future policy and programming include consolidating data for reproductive health indicators, ensuring type of information needed is captured at all levels, and reducing provider workload for reporting.

Long-term follow-up of phacotrabeculectomy surgery in Tanzania.

INTRODUCTION: The glaucomas often co-exist with cataract. We previously reported a large trial of anti-scarring treatment in combined phacotrabeculectomy surgery. Long-term outcomes in an African population are extremely rarely reported. We present here the outcomes in IOP, acuity, bleb morphology and patient perceptions at 3-5-years post surgery. METHODS: Tanzanian patients with glaucoma and visually significant cataract underwent combined phacotrabeculectomy surgery. In November 2015 an attempt was made to contact all participants in the study inviting them for a repeat examination. All who attended were given a detailed examination. A semi-structured interview in Swahili was administrated to determine patient experience and satisfaction with the surgery. RESULTS: Sixty-eight (23%) attended for repeat review in 2015. The mean time from original surgery was 4.5-years (range 2.3-6.6-years). Overall 53 (78%) had IOP < 21 mm Hg and 29 (43%) an IOP < 16 mm Hg at final follow-up. A flat bleb at 26 and 100 days was associated with failure by IOP criteria at 4.5-years post-operatively. A vascular bleb at those time points was not any more associated with late failure than a non-vascular bleb. A majority of patients were pleased with the surgery. The cost of surgery is high but it is a price patients were willing to pay. Nearly all patients (95%) would recommend the service to family and friends. DISCUSSION: Owing to the small proportion reviewed, our conclusions are severely limited. Phacotrabeculectomy worked well in a majority of the reviewed population long-term and is accepted by a majority of these patients as worthwhile.

Factor analysis and validation of a self-report measure of impaired fear inhibition.

Difficulties with inhibiting fear have been associated with the emergence of anxiety problems and poor response to cognitive-behavioural treatment. Fear inhibition problems measured using experimental paradigms involving aversive stimuli may be inappropriate for vulnerable samples and may not capture fear inhibition problems evident in everyday life. We present the Fear Inhibition Questionnaire (FIQ), a self-report measure of fear inhibition abilities. We assess the FIQ's factor structure across two cultures and how well it correlates with fear inhibition indices derived experimentally. Adolescent participants from Hong Kong and England completed the FIQ, with the English participants also completing a conditioning and extinction task to assess fear inhibition problems. Across both cultures, the FIQ showed a single factor structure and low FIQ scores, or worse fear inhibition problems, were associated with self-reports of heightened anxiety. Correlation of FIQ scores with experimental indices, whilst controlling for anxious symptoms, suggests that the FIQ represents a valid and unique measure of fear inhibition abilities. The FIQ might be used to assess more ecologically valid fear inhibition problems particularly amongst people who have or who are at risk of anxiety diagnoses.

Problematic attention processing and fear learning in adolescent anxiety: Testing a combined cognitive and learning processes model.

BACKGROUND AND OBJECTIVES: Anxiety in adolescence is characterised by disturbances in attentional processes and the overgeneralisation of fear, however, little is known about the combined and reciprocal effects of and between these factors on youth anxiety. The present study investigated whether attention (attention allocation and control) and fear generalisation processes together predict more variance on adolescent anxiety symptoms than each factor in isolation, and explored their interrelations. METHODS: 197 adolescents completed a novel conditioning task, which paired balloon cues with mildly aversive or neutral outcomes. A spatial cueing task, and self-report measures of emotional attentional control and anxiety, were also completed. RESULTS: Threat-avoidant attention allocation biases, impaired attention control, and exaggerated fear generalisation together predicted greater variance in anxiety symptoms (55.3%), than each set of fear and attention processes in isolation. Results also provided evidence of an interplay between these factors. Individual differences in threat-avoidant attention allocation biases predicted variability in the generalisation of fear, whilst the association between heightened anxiety and the overgeneralization of fear was moderated by poor attention control. CONCLUSIONS: This study provides unique evidence of the combined effects of attention and fear generalisation mechanisms in explaining youth anxiety, and interrelations between these factors. Importantly, results suggested that deficiencies in attention control may bring out anxiety-associated impairments in fear generalisation. LIMITATIONS: We relied on self-reported ratings of fear during generalization and also of attention control. Thus demand effects cannot be discounted. Reaction-time measures of attention focus are also indirect assessments of attention that may lack precision.

Glaucoma Control Strategies in Sub-Saharan Africa: A Review of the Clinical and Health Economic Evidence.

PURPOSE: A review of the effectiveness, costs, and cost-effectiveness of detection and treatment strategies for glaucoma control in Sub-Saharan Africa (SSA) was conducted. METHODS: Detailed searches were performed using the Ovid Medline, Ovid Embase, The Cochrane Library, Web of Science, Scopus, and LILACS databases up to September 2016. The key Medical Subject Heading search terms used included glaucoma, diagnosis, treatment, effectiveness, costs, cost-effectiveness, and Sub-Saharan Africa. Effectiveness was measured as the proportion of study participants with an intra-ocular pressure less than or equal to 22 mmHg. RESULTS: A total of 5658 records were examined with 48 papers identified. The sensitivity and specificity of portable instruments or smartphone technologies to detect glaucomatous changes ranged from 58.3% to 93.8% and from 82.4% to 96.8%, respectively. The overall effect size for various glaucoma interventions was: 0.39 (95% confidence interval (CI) 0.27-0.54, I2 = 64.85, p = 0.036) for laser trabeculoplasty; 0.56 (95% CI 0.23-0.84, I2 = 85.74, p = 0.001) for drainage implant devices; 0.66 (95% CI 0.61-0.71, I2 = 0.00, p = 0.402) for medical management; and 0.73 (95% CI 0.65-0.80, I2 = 93.25, p = 0.000) for all other non-drainage tube surgical interventions, including trabeculectomy surgery and the use of anti-metabolites. The mean annual cost of anti-glaucoma drugs across SSA was USD 394, with a mean direct non-medication cost per year of USD 54, and a mean surgical cost per year of USD 283. CONCLUSIONS: While effective glaucoma control interventions exist, their widespread use and diffusion across SSA remain challenging principally due to low per capita income levels and high glaucoma treatment costs.

"Give What the People Want": A Situational Analysis of Condom Distribution and a Feasibility Study of User-Friendly Condoms in Cape Town, South Africa.

Condom use has remained low in South Africa despite efforts by the government to make condoms accessible to all. We assessed condom availability, procurement/distribution, and education practices, and explored perceptions of and interest in an expanded array of condom options, including fitted male condoms in Cape Town, South Africa. We conducted 11 key informant interviews with staff members from two sexual health organizations and four state-owned clinics. Key informants (a) were interested in their organizations offering an expanded variety of male condom options including different sizes, colors, and flavors; and (b) substantiated the capacity that their organizations had to integrate alternative condom options into existing procurement, distribution, and education programs. Challenges discussed included securing funding, educating clients, and addressing logistical issues of stocking and distributing new condom types. Further research should explore whether providing condoms with a greater array of characteristics could improve condom use in South Africa.

Women in Osteopathic and Allopathic Medical Schools: An Analysis of Applicants, Matriculants, Enrollment, and Chief Academic Officers.

In the 1993-1994 academic year, female enrollment was 34.7% in osteopathic medical schools and 40.2% in allopathic medical schools. To assess progress in female enrollment since that time, the authors examined admission data in the ensuing years, including female applicants, matriculants, and first-year students in osteopathic and allopathic medical schools, as well as female chief academic officers at these institutions. In the 2004-2005 academic year, 50.3% of first-year students in osteopathic medical schools were women; however, by the 2013-2014 academic year, that figure dropped to 44.2%. The percentage rose slightly by the 2016-2017 academic year to 45.9%. Additionally, for the 2016-2017 academic year, allopathic medical schools had a significantly higher proportion of female matriculants than did osteopathic medical schools (49.8% vs 45.9%, respectively; P<.001).

Determining Psychoneuroimmunologic Markers of Yoga as an Intervention for Persons Diagnosed With PTSD: A Systematic Review.

There is a growing body of research on yoga as a therapeutic intervention for psychological symptoms of post-traumatic stress disorder (PTSD) accompanied by speculations on underlying physiologic mechanisms. The purpose of this systematic review is to identify, qualitatively evaluate, and synthesize studies of yoga as an intervention for PTSD that measured physiologic outcomes in order to gain insights into potential mechanisms. The focus is on studies evaluating yoga as a therapeutic intervention for PTSD rather than for trauma exposure, PTSD prevention, or subclinical PTSD. Multiple databases were searched for publications from the past two decades using terms derived from the question, "In people with PTSD, what is the effect of yoga on objective outcomes?" Eligibility criteria included yoga-only modalities tested as an intervention for formally diagnosed PTSD with at least one physiologic outcome. Results of this review confirmed that, though much of the published literature proposes physiological mechanisms underlying yoga's effects on PTSD, very few studies ( n = 3) have actually evaluated physiological evidence. Additionally, several studies had methodological limitations. In light of the limited data supporting yoga's beneficial effects on autonomic nervous system dysregulation, we present a theoretical model of the psychoneuroimmunologic processes associated with PTSD and the effects yoga may have on these processes to guide future research. Gaps in the literature remain for mechanisms related to activation of the hypothalamic-pituitary-adrenal axis and inflammation. Additional rigorous mechanistic studies are needed to guide development of effective yoga interventions for PTSD to augment existing evidence-based PTSD treatments.
