Boosting Contraceptive Uptake in Urban Uganda: Older Women Benefit When Layering Adolescent and Youth Interventions Onto Existing Family Planning Programming

INTRODUCTION

Uganda has a large young population with a high unmet need for family planning (FP). Although there have been many efforts to improve access to and uptake of contraception, improvements have been slow. The Ministry of Health Uganda partnered with The Challenge Initiative (TCI) to implement a novel multipronged approach layering adolescent and youth sexual reproductive health (AYSRH) onto a functioning general FP program for women of reproductive age in 3 local governments of Buikwe, Mukono, and Iganga. We describe the approach and aim to determine whether layering AYSRH interventions onto an existing program resulted in increased contraceptive uptake among adolescents and youth aged 10-24 years and among women aged 25-49 years.

METHODS

We analyzed service statistics from the Uganda Health Management Information System to assess contraceptive uptake for adolescents and youth (aged 10-24 years) and older women (aged 25-49 years) before and after the implementation of the AYSRH approach in 3 areas (Buikwe, Iganga, and Mukono) compared to 11 areas where only the general FP program was implemented and the Uganda country total.

RESULTS

This analysis showed that before the start of TCI's support, levels of contraceptive uptake were similar in all local governments. However, after implementation, there was an increase in uptake for general FP program only areas (1.7-point advantage over country total) and an even greater increase in general FP+AYSRH areas (2.4-point advantage over FP only programming). This was observed in both adolescents and youth aged 10-24 years and among women aged 25-49 years.

CONCLUSION

The layering of TCI's AYSRH interventions onto a well-functioning FP platform not only increased contraceptive uptake among adolescents and youth aged 10-24 years but also boosted uptake among women older than age 25 years.

Implementing Quality Improvement Initiatives to Improve the Use of Adolescent- and Youth-Friendly Health Services in Zou, Benin

INTRODUCTION

In Benin, the unmet need for family planning services is especially high for adolescent girls and youth aged 15-24 years. The Challenge Initiative (TCI) supported the health system to assess and improve the quality of adolescent and youth sexual reproductive health services and enhance contraceptive uptake in 65 service delivery points (SDPs) of the Zou department.

PROGRAM DESCRIPTION

Between June 2019 and March 2021, TCI supported the health districts in Zou to train an assessment team to complete 3 cycles of quality assessments (QAs) using a QA checklist adapted to the local context. Based on assessment scores, the SDPs were categorized into poor, moderate, or good to excellent quality. The SDP managers developed remedial action plans after each cycle and for each SDP and followed up with supportive supervision.

RESULTS

The first QA cycle showed that 52% of assessed SDPs achieved a good to excellent classification; by the second QA cycle, this reached 74%. However, the quality of adolescent- and youth-friendly health services regressed during the third QA cycle (during COVID-19 pandemic disruptions), when only 40% of SDPs achieved the good to excellent category. Between the first and second QA cycles, contraceptive uptake for adolescents and youth improved in the SDPs that had good or excellent quality of services, compared to the ones that were of lower quality (established significance level of 5% with a P value of .031).

CONCLUSION

Further assessments could deepen our understanding of the internal and external factors that can affect service quality. The findings reinforce the importance of investing in quality improvement strategies to maximize the use of sexual and reproductive health services among adolescents and youth. They also underscore the need for a contextual and nuanced approach to ensure enduring results.

Student learning of head and neck anatomy using cone beam computed tomography and immersive virtual reality

OBJECTIVES

The purpose of this study was to evaluate the efficacy of student learning of anatomy and 3D imaging concepts using cone beam computed tomography (CBCT) and immersive virtual reality (VR) technology.

METHODOLOGY

Ninety (n = 90) first year dental students with no previous experience in 3D imaging were recruited. All participants completed a 10-item, multiple-choice questionnaire (MCQ) and a pre-survey prior to the educational intervention. Following a brief video orientation on CBCT and anatomy, each participant underwent a one-on-one educational intervention using immersive VR with calibrated instructors to identify head and neck anatomic structures using a VR/CBCT educational tool. Immediately following the intervention, all participants completed a postsurvey, a second MCQ, NASA task load index and presence questionnaires. Participants completed a third MCQ 2 weeks following the intervention. Analysis of objective measures of performance on MCQ's (p < 0.05) and subjective data from the questionnaires was completed.

RESULTS

The students doubled their mean test scores 2.45 ± 1.274 to 5.99 ± 1.576 on MCQ's immediately following the educational intervention (p < 0.05). The significant increase in the MCQ test scores was maintained after 2 weeks, 5.73 ± 1.721 (p < 0.05). There were no gender differences in student test performance. Students rated the immersive VR/CBCT educational intervention experience highly for control, sensory, and realism factors with minimal distraction and frustration factors.

CONCLUSION

Results from this study show that immersive VR/CBCT educational intervention improved test performance and contributed to information recall in students. Further benefits reported by participants include the sense of presence and increased engagement using immersive VR.

Scaling Access to Contraception for Youth in Urban Slums: The Challenge Initiative's Systems-Based Multi-Pronged Strategy for Youth-Friendly Cities

INTRODUCTION

More than half of all adolescents globally live in Asia, with India having the largest adolescent population in the world at 253 million. In sub-Saharan Africa, adolescents make up the greatest proportion of the population, with 23% of the population aged 10-19. And these numbers are predicted to grow rapidly-particularly in urban areas as rural youth migrate to cities for economic opportunities. While adolescents and youth are subject to high sexual and reproductive health risks, few efforts have been documented for addressing these in urban settings, especially in poor settlements.

METHODS

The Challenge Initiative (TCI) is a demand-driven, family planning platform for sustainable scale and impact that lets city governments-in particular urban slums-lead implementation. It is currently active in 11 countries in Africa and Asia. In June 2018, TCI heightened its focus on adolescent and youth sexual and reproductive health (AYSRH) for youth living in urban slums. It now supports 39 city governments. TCI dedicates technical and program support to married (including first-time parents) and unmarried youth ages 15-24 years. Using an innovative coaching model and an online learning platform (TCI University), TCI supports city governments as they implement AYSRH interventions to accelerate the impact of TCI's model for rapid scale.

RESULTS

TCI has been assessing the performance of cities implementing its AYSRH approaches using its RAISE tool and has found considerable improvement over two rounds of assessments through TCI coaching and support for adaptation of its high-impact interventions between the first and second round.

CONCLUSIONS

TCI's AYSRH approach scaled rapidly to 39 cities and multiple urban slums since 2018, using its evidence-based interventions and coaching model. In the context of universal health coverage, TCI has supported segmented demand generation and improved access to quality and affordable contraceptive as well as youth-friendly health services. It provides a menu of interventions for cities to implement for youth-including such approaches as public-private partnerships with pharmacies and quality assurance using quick checklists-along with an innovative coaching model. This approach has facilitated greater access to contraceptive methods of choice for youth.

Planting the Seeds: Insights for Researchers Interested in Working With Indigenous Peoples

Health research in Canada carries a history of exploitation and cultural insensitivity in its approaches, resulting in a deeply rooted mistrust among Indigenous Peoples. Communities are signalling the urgent need for health research to be conducted in a more conscientious way. To address these gaps, our team of three Elders and three researchers co-developed a series of workshops in the province of British Columbia, Canada, in 2019 to increase participants’ knowledge and skills for conducting culturally responsive health research. Workshops examined power and privilege; self-awareness/self-reflection; Indigenous and Western worldviews; cultural safety; allyship; and research principles and practices. Activities were experiential and privileged Indigenous knowledges. An Indigenous-informed evaluation captured participants’ experiences via online surveys. Participants described workshop learnings as deeply impacting ways they approach research practice. Thematic analysis of participant reflections revealed three overarching themes: bringing together the mind and the heart; self-reflection and initiating change; and understanding cultural safety as a lifelong journey. Lessons learned by facilitators included the importance of applying Indigenous ways of knowing to create safe spaces for healing and learning; empowering participants to critically self-reflect; and rooting the work in ceremony. The ethical responsibility to allow time and space for meaningful dialogue was crucial for aligning with Indigenous protocols of coming together. This project demonstrates that experiential workshops, co- facilitated by Elders and researchers, are an innovative, effective, and Indigenous-centred approach for providing education on how to engage in culturally safe and culturally resonant research.

Sensory Modulation, Anxiety, and Interoception in Typical Adults

Date Presented 03/26/20

Despite the coexistence of sensory modulation disorder (SMD), anxiety, and altered interoceptive awareness (AIA) in adults, correlations between these constructs are limited in existing literature. This study examined a sample of over 150 typical adults and found moderate correlations between SMD, anxiety, AIA, and quality of life. Understanding correlations between these constructs may contribute to a better understanding of impact on occupations and more efficacious OT interventions.

[Necrozoospermia: From etiologic diagnosis to therapeutic management]

This review describes necrospermia, its diagnosis, causes and management. Sperm vitality is commonly assessed in the laboratory of reproductive biology, with the eosin test or with the hypo-osmotic swelling test. Necrospermia is defined by a percentage of living spermatozoa inferior to 58%, and can be related to male infertility. Several pathological mechanisms may be involved and can be classified either in testicular causes (hyperthyroidism, local hyperthermia, varicocele), or post-testicular causes (epididymal necrospermia, dysregulation of seminal plasma, adult polycystic kidney disease, vasectomy reversal, anti-sperm antibodies) or both (infection, toxic, age, spinal cord injury). The first treatment is to correct the underlying cause, if possible. Repetitive ejaculation has demonstrated to be effective as well. Many drugs would also improve the sperm vitality (antioxidants, non-and-steroidal anti-inflammatory drugs) but there is currently no guideline to recommend their use. With necrospermia, fertilization rates are lower but in vitro fertilization (IVF) with Intracytoplasmic sperm injection (ICSI) improves the chances of conception.

Extreme spermatogenesis failure: andrological phenotype and intracytoplasmic sperm injection outcomes

Patients with very low sperm count through direct sperm examination can exhibit extreme oligozoospermia or cryptozoospermia (after centrifugation). The management of these patients is a real challenge for both clinicians and biologists. In this retrospective and comparative cohort study, we compared the andrological phenotype of patients with extreme alterations of spermatogenesis and assessed whether the origin of spermatozoa (testicular or ejaculate) had any influence on intracytoplasmic sperm injection (ICSI) outcomes. A total of 161 ICSI cycles were performed using ejaculated spermatozoa from 75 patients with extreme oligozoospermia (EOS) or cryptozoospermia (CS) and 150 ICSI cycles using extracted testicular spermatozoa from 74 patients with non-obstructive azoospermia (NOA). Physical, hormonal, ultrasound assessments, and ICSI outcomes were performed in each group. Cryptorchidism was significantly more frequent in the NOA group (60.8% vs. 22.6%, p = 0.001). FSH levels were significantly higher [18.9 IU/L (5.9-27.0) vs. 15.3 IU/L (9.0-46.5), p = 0.001] and the majority of inhibin B levels measured were found mostly undetectable in the NOA group as compared to EOS/CS group (31.1% vs. 10.7%, p = 0.0004). Moreover, we found no significant differences in the respect to the fertilization rates (48.9% and 43.3%, p = 0.43), implantation rates (17.4% and 15.9%, p = 0.77), and percentage of top quality embryo (22.4% and 20.4%, p = 0.73) between the two groups. The clinical pregnancy rates per embryo transferred were comparable in both groups (28.3% and 27.4%, p = 0.89). In this study, we showed for the first time a different andrological phenotype between EOS/CS and NOA groups. Indeed, cryptorchidism was significantly more frequent with more severe endocrine parameters found in the NOA group. These results reflect a more profound alteration in spermatogenesis in NOA patients. However, there was no difference in ICSI outcomes between NOA and EOS/CS groups.

Mobile Health Technology Can Objectively Capture Physical Activity (PA) Targets Among African-American Women Within Resource-Limited Communities-the Washington, D.C. Cardiovascular Health and Needs Assessment

BACKGROUND

Little is understood about using mobile health (mHealth) technology to improve cardiovascular (CV) health among African-American women in resource-limited communities.

METHODS

We conducted the Washington, D.C. CV Health and Needs Assessment in predominantly African-American churches in city wards 5, 7, and 8 with the lowest socioeconomic status based on community-based participatory research (CBPR) principles. The assessment measured CV health factors: body mass index (BMI), fasting blood glucose and cholesterol, blood pressure, fruit/vegetable (F/V) intake, physical activity (PA), and smoking. Participants were trained to use a PA monitoring wristband to measure 30 days of PA, wirelessly upload the PA data to hubs at the participating churches, and access their data from a church/home computer. CV health factors were compared across weight classes.

RESULTS

Among females (N = 78; 99 % African-American; mean age = 59 years), 90 % had a BMI categorized as overweight/obese. Across weight classes, PA decreased and self-reported sedentary time (ST) increased (p ≤ 0.05). Diastolic blood pressure and glucose increased across weight classes (p ≤ 0.05); however, cholesterol, glucose, and BP were near intermediate CV health goals.

CONCLUSIONS

Decreased PA and increased ST are potential community intervention targets for overweight and obese African-American women in resource-limited Washington D.C. areas. mHealth technology can assist in adapting CBPR intervention resources to improve PA for African-American women in resource-limited communities.

Leydig cell tumor of the testis with azoospermia and elevated delta4 androstenedione: case report

Background

Secreting interstitial cell (Leydig cell) tumors are rare. In adults, the clinical picture and steroid levels are variable.

Case presentation

This paper presents a case of left testicular tumor, showing azoospermia with normal serum level of total testosterone, collapsed FSH and LH, and high delta4 androstenedione. Histopathological investigation revealed a Leydig cell tumor. TESE allowed spermatozoa extraction and freezing. Testicular histology found hypospermatogenesis and germ-cell aplasia with interstitial fibrosis. Surgical resection of the tumor resulted in normalization of gonadotropins and fall in serum delta4 androstenedione to subnormal levels in the postoperative period confirming that the tumor was secreting delta4 androstenedione. It was hypothesized that high delta4 androstenedione resulted in intra tumoral 17 β-HSD overtaken by delta4 androstenedione or that 17 β-HSD activity in the tumor was different from that of normal Leydig cells. Three months after surgery sperm analysis found a complete recovery of spermatogenesis. A spontaneous pregnancy occurred 3 months after surgery and a girl was born.

Conclusions

In this case, the diagnosis of testicular Leydig cell tumor secreting delta4 androstenedione was made in a context of azoospermia.

Outcome of neonates ventilated in the main intensive care unit at The University Hospital of the West Indies: a 15-year experience

A 15-year retrospective review of neonates ventilated in the main intensive care unit at the University Hospital of the West Indies was conducted. During the study period, 153 neonates were ventilated, of whom 80 (52%) survived. The most common reason for admission was respiratory distress syndrome, which accounted for 67% (102/153) of admissions, 53 (52%) of these infants survived. Improving outcome will require strategies directed at improving neonatal intensive care.

[The testicular microtubule-associated protein Tau: Where, when during spermatogenesis?]

The Tau protein (Tubulin Associated Unit) is a phosphoprotein of the microtubule-associated protein family (MAPs). Its role is the regulation of the microtubule polymerization. The Tau protein is naturally present in brain, heart, muscle, lung, kidney, pancreas and liver. An expression of Tau protein and RNA messengers was also highlighted in the testis that is an organ rich in microtubules. The role of microtubules is essential in the stabilization of the cellular shape and in cell divisions. In the testis, Tau protein could be involved in the division process of the spermatogenesis by acting on the microtubular dynamics in the arrangement of the spermatozoon polarity. This review synthesizes the current knowledge, the localization and the main functions of the Tau protein focused on the testis. The localization and the potential roles of the Tau protein during the spermatogenesis are discussed by emphasizing the link with the microtubular structures of seminiferous tubules.

[Azoospermia and a history of inguinal hernia repair in adult]

BACKGROUND

Inguinal hernia repair is one of the most performed surgeries in the world. It is recognized that any surgery of the pelvic floor may represent a risk factor of male infertility.

METHOD

Retrospective study of patients with azoospermia and a history of adult inguinal hernia repair surgery and referred to our center between January 1990 and January 2011 for infertility.

RESULTS

Among 69 azoospermia patients with history of adult inguinal hernia repair surgery, 60 patients underwent surgical extraction of sperm that was successful in 75% (45/60). Positive extraction rate decreases in the subgroup of patients with risk factors for infertility (61.4%) as well as in the group with bilateral inguinal hernia (67.9%). There was no statistically significant difference in the positive rate of sperm retrieval according to surgical technique or according to the use of polypropylene mesh (P>0.05).

CONCLUSION

The obstruction of the vas deferens due to an inguinal hernia repair was a potential iatrogenic cause of male infertility that was rare and underestimated. The influence of using a polypropylene mesh was not clearly demonstrated. The management of these patients is based on prevention in order to identify patients with risk factors of infertility in order to propose a presurgery cryopreservation of sperm.

Leveraging the Power of Knowledge Management to Transform Global Health and Development

Good knowledge is essential to prevent disease and improve health. Knowledge management (KM) provides a systematic process and tools to promote access to and use of knowledge among health and development practitioners to improve health and development outcomes. KM tools range from publications and resources (briefs, articles, job aids) and products and services (websites, eLearning courses, mobile applications), to training and events (workshops, webinars, meetings) and approaches and techniques (peer assists, coaching, after-action reviews, knowledge cafés).

Congenital bilateral absence of the vas deferens: the impact of spermatogenesis quality on intracytoplasmic sperm injection outcomes in 108 men

In azoospermic men with congenital bilateral absence of the vas deferens (CBAVD), it is not known whether the outcomes of intracytoplasmic sperm injection (ICSI) depend on the quality of testicular spermatogenesis (as determined histopathologically). We retrospectively studied the impact of spermatogenesis quality on ICSI outcomes in 108 azoospermic men with CBAVD consulting in a university hospital's department of andrology and reproductive biology. As part of an ICSI program, sperm samples were obtained from the epididymis [by microsurgical epididymal sperm aspiration (MESA); n = 47] or the testis [by testicular sperm extraction (TESE); n = 14] or both (MESA + TESE, n = 47). In the TESE group (i.e., TESE-only and MESA + TESE), spermatogenesis was normal in 21 of the 108 men (19.4%) and hypospermatogenesis occurred in 33 (30.5%). The fertilization rate was significantly lower in the hypospermatogenic group than in the normospermatogenesis group (65.6 and 72.9%, respectively; p = 0.02); this was also true for the embryo cleavage rate (88.6 and 92.1%, respectively; p = 0.007), and the proportion of embryos with fewer than 30% of enucleate fragments (79.5 and 86.9%, respectively; p = 0.02). Our study results showed that impaired spermatogenesis had a negative impact on certain early-stage biological outcomes of ICSI. In CBAVD, male factors are likely to exert a harmful effect on the early stages of embryo development.

Nordihydroguaiaretic acid activates hTRPA1 and modulates behavioral responses to noxious cold in mice

Nordihydroguaiaretic acid (NDGA) is a major biologically active component of the creosote bush, Larrea tridentate, widely used in unregulated therapies. NDGA is a lipoxygenase inhibitor while a derivative, terameprocol, has been trialed as a chemotherapeutic agent. When investigating fatty acid activation of the human transient receptor potential cation channel subfamily A, member 1 (hTRPA1), we found that NDGA activated the channel. Here we investigate the actions of NDGA and terameprocol at hTRPA1 and the consequences of this for noxious cold sensitivity in mice. hTRPA1 was stably expressed in HEK 293 cells (HEK 293-TRPA1) and channel activity examined by measuring changes in intracellular calcium ([Ca]_i) using a fluorescent dye and activation of membrane currents using patch clamp electrophysiology. The effects of local NDGA and terameprocol application on acetone-induced paw flinching were examined in mice. NDGA (pEC₅₀ of 5.4 ± 0.1, maximum change in fluorescence of 385 ± 30%) and terameprocol (pEC₅₀ 4.5 ± 0.2, maximum 550 ± 75%) increased [Ca]_i in HEK 293-hTRPA1 cells. NDGA also induced an increase in membrane conductance in HEK 293-hTRPA1 cells. These effects were prevented by the TRPA1 antagonist HC-030031, and were dependent on the presence of Cys621, Cys 641, and Cys 665 in hTRPA1. Neither NDGA nor terameprocol alone produced spontaneous pain behaviors in mice after hind paw injection, but both enhanced responses to acetone. NDGA and terameprocol are efficacious activators of TRPA1. NDGA should be used with care to probe lipoxygenase involvement in nociception while TRPA1 activity should be considered when considering use of these drugs in humans.

Light microscopy morphological characteristics of the sperm flagellum may be related to axonemal abnormalities

Although electron microscopy provides a detailed analysis of ultrastructural abnormalities, this technique is not available in all laboratories. We sought to determine whether certain characteristics of the flagellum as assessed by light microscopy were related to axonemal abnormalities. Forty-one patients with an absence of outer dynein arms (type I), a lack of a central complex (type III) and an absence of peripheral doublets (type IV) were studied. Sperm morphology was scored according to David's modified classification. Flagella with an irregular thickness were classified as being of normal length, short or broken. There were correlations between missing outer dynein arms and abnormal, short or coiled flagellum. Type III patients showed the highest flagellar defects (a short (P = 0.0027) or an absent flagellum (P = 0.011)). Just over 68% of the irregular flagella were short in Type III patients, whereas this value was only 34.5% in type I and 26.4% in type IV (P = 0.002). There was a negative correlation between misassembly and spermatozoa of irregular flagella (r = -0.79; P = 0.019). It is concluded that light microscopy analysis of flagellum abnormalities may help provide a correct diagnosis, identify sperm abnormalities with fertility potentials and outcomes in assisted reproduction technologies and assess the genetic risk.

[ICSI treatment in severe asthenozoospermia]

In the management of asthenozoospermia, the spermogram-spermocytogram plays an important role during diagnosis. It is of major importance to distinguish between necrozoospermia and sperm vitality. An ultrastructural study of spermatozoa is processed in the case of primary infertility without female implication, severe, unexplained and irreversible asthenozoospermia, sperm vitality at least 50 % and normal concentration of spermatozoa. Ultrastructural flagellar abnormalities are numerous and involve most spermatozoa. ICSI provides a suitable solution for patients with sperm flagellar defects to conceive children with their own gametes but the rate of ICSI success may be influenced by the type of flagellar abnormality. Some fertilization and birth rate failures which are related to some flagellar abnormalities might occur.

Measures of small-fiber neuropathy in HIV infection

INTRODUCTION

Noninvasive methods are needed to detect distal sensory polyneuropathy in HIV-infected persons on antiretroviral therapy (ART).

METHODS

Quantitative sudomotor axon reflex test (QSART) and Utah Early Neuropathy Scale (UENS), small-fiber sensitive measures, were assessed in subjects with and without clinical neuropathy. Pain was assessed by visual analog scale (VAS).

RESULTS

Twenty-two subjects had symptoms and signs of neuropathy, 19 had neither, and all were receiving ART. Median sweat volume (μL) was lower at all testing sites in those with neuropathy compared to those without (p<0.01 for all). UENS and VAS (mm) were higher in neuropathy subjects (p<0.05 for each). Lower sweat volume at all sites correlated with higher pin UENS subscore, total UENS, and VAS (p<0.05 for all). In multivariable analyses adjusting for age, CD4⁺ T cells, sex, and use of "d-drug" ART, QSART and UENS remained associated (p=0.003).

CONCLUSION

QSART and UENS have not been previously studied in this patient population and may identify small-fiber neuropathy in HIV-infected, ART-treated persons.

Difficult Airway Society Guidelines for the management of tracheal extubation

Tracheal extubation is a high-risk phase of anaesthesia. The majority of problems that occur during extubation and emergence are of a minor nature, but a small and significant number may result in injury or death. The need for a strategy incorporating extubation is mentioned in several international airway management guidelines, but the subject is not discussed in detail, and the emphasis has been on extubation of the patient with a difficult airway. The Difficult Airway Society has developed guidelines for the safe management of tracheal extubation in adult peri-operative practice. The guidelines discuss the problems arising during extubation and recovery and promote a strategic, stepwise approach to extubation. They emphasise the importance of planning and preparation, and include practical techniques for use in clinical practice and recommendations for post-extubation care.

Correlation between testicular sperm extraction outcomes and clinical, endocrine and testicular histology parameters in 120 azoospermic men with normal serum FSH levels

We retrospectively evaluated the clinical and hormonal profiles, sperm extraction outcomes and testicular histology parameters in 120 azoospermic men with normal serum follicle-stimulating hormone (FSH) level. Microsurgical epididymal sperm aspiration (MESA) and testicular sperm extraction (TESE) were performed in 33 and 87 cases, respectively. Sperm were successfully retrieved in all the MESA procedures and in 65 of the TESE procedures. The mean serum FSH and inhibin B levels and the testicular volume differed significantly according to whether or not sperm were retrieved. The threshold serum inhibin B value for predicting successful TESE was 123.5pg/mL (sensitivity: 69.7%; specificity: 66.7%). The 13 patients with Sertoli cell only syndrome (SCOS) had a higher mean serum FSH level and a lower mean serum inhibin B level than the other phenotypes. TESE was negative for 11 of the 13 SCOS men. The mean±SD inhibin B level was significantly lower in patients with 5-10IU/L of FSH than those with 2-5IU/L of FSH (108.30±53.86 vs. 175.23±70.17pg/mL, respectively). The sperm retrieval rates were 71.42% for the group with 5-10IU/L of FSH and 87.32% for the group with 2-5IU/L of FSH. Ten of the 13 SCOS men had a FSH level between 5 and 10IU/L. The clinical pregnancy rate was significantly lower (p=0.04) in the group with 5-10IU/L (50%) of FSH than in the group with 2-5IU/L (77.5%) of FSH. In conclusion, there is no FSH value below which spermatogenesis is always found. Inhibin B assays and clinical assessments are thus of particular value in men with normal serum FSH levels.

Prise en charge de l’infécondité dans les troubles de l’éjaculation: avis conjoints de l’andrologue, du biologiste et du gynécologue

Quatre-vingts pour cent des hommes qui présentent des troubles de l’éjaculation sont en âge de procréer, mais seul 5 à 10 % en sont spontanément capables. Du sperme antérograde et/ou rétrograde peut être recueilli par éjaculation assistée en association à des traitements pharmacologiques (chlorhydrate de minodrine-vibroéjaculation). En cas d’échecs de recueil de sperme et d’azoospermie, l’extraction chirurgicale des spermatozoïdes épididymaires ou testiculaires permet d’obtenir des spermatozoïdes, en quantité généralement moins importante que les techniques d’éjaculation assistée, mais non infectés et dépourvus de plasma séminal (souvent délétère dans les troubles de l’éjaculation). Même en cas d’éjaculation antérograde, il est impératif de recueillir les urines systématiquement à la recherche d’une éjaculation rétrograde, fréquente dans les troubles de l’éjaculation. Au laboratoire, l’analyse du sperme et de l’urine s’effectue par les méthodes de routine standardisées. La plupart des hommes présentant des troubles de l’éjaculation ont un sperme de mauvaise qualité (asthénospermie, nécrospermie, leucospermie). Les étiologies de la dégradation des paramètres du sperme sont multifactorielles, d’origine centrale et périphérique (testiculaire et extratesticulaire). Optimiser la qualité du sperme et des spermatozoïdes reste un challenge d’actualité dans les troubles de l’éjaculation. Si la cryopréservation doit être systématique, l’utilisation du sperme frais optimisé a généralement la préférence. Réussir à obtenir du sperme offre au couple une chance de grossesse naturelle (rarement) grâce à une éjaculation coïtale, par auto-insémination, par insémination intra-utérine, par fécondation in vitro conventionnelle (FIVc) ou injection intracytoplasmique de spermatozoïdes (ICSI) dans l’ovocyte. Dans les troubles de l’éjaculation, la prise en charge de la fécondité de l’homme doit être la plus rapide possible. Elle s’effectue conjointement à celle de la femme par une équipe coordonnant l’andrologue, le biologiste et le gynécologue.

Introducing new vaccines in the poorest countries: what did we learn from the GAVI experience with financial sustainability?

This paper reviews the experience of the Global Alliance for Vaccines and Immunization (GAVI) in introducing hepatitis B and Haemophilus influenzae type b vaccines in the poorest countries, and explores how financing for immunization has changed since GAVI Fund resources were made available during its first wave of support between 2000 and 2006. The analysis of Financial Sustainability Plans in 50 countries allowed for some of the original funding assumptions of the GAVI approach to be tested against the realities in a wide set of countries, and to highlight implications for future immunization efforts. While the initial GAVI experience with financial sustainability has proved successful through the development of plans, and many countries have been able to both introduce new vaccines and mobilize additional financing for immunization, for future GAVI supported vaccine introduction, some country co-financing of these will be needed upfront for the approach to be more sustainable.
