Pre-service education and continuous professional development on female genital mutilation/cutting for maternal health professionals in OECD countries: A scoping review.

BACKGROUND: Female Genital Mutilation/Cutting can cause sequalae throughout pregnancy, childbirth, and the postpartum period. Due to changing patterns in migration flows, the practice evolved into a global phenomenon. Health professionals should ensure high quality of care during maternity service provision. OBJECTIVE: This scoping review aimed to map available evidence on pre-service and continuous professional development education about Female Genital Mutilation/Cutting for maternal health professionals and identify developmental needs for topic inclusion into teaching. METHODOLOGY: The review was conducted in accordance with the PRISMA-ScR guidelines. A protocol was developed and is publicly available (medRxiv 2022.08.16.22278598). Three databases (CINAHL, Embase, Medline) and other educational sources were searched. During the final stages of the review an ethical application was submitted and approved. Expert interviews were added to gain insights from practice. RESULTS: The search identified 224 records. After title and abstract screening, 33 studies were selected for full-text review, resulting into the inclusion of 4 studies and 12 non-research educational sources. Scoping the topic revealed that Female Genital Mutilation/Cutting is often included ad-hoc or stand-alone during trainings and it remains unclear, who owes the responsibility. There is lack of knowledge about which competencies are needed for the different levels of health cadres, how competencies are achieved and outcomes measured. CONCLUSION: More transparency into training on Female Genital Mutilation/Cutting and about how competency levels are achieved, maintained and evaluated is required. Further research and interdisciplinary collaboration could focus on the development of specific modules and lead to service improvement.

A Challenging Case of Oral Ulcers and Gastrointestinal Bleeding: Crohn's or Behçet's Disease.

Introduction. Differentiating Crohn's disease (CD) and Behçet's disease (BD) with gastrointestinal (GI) manifestations can be clinically challenging, as current diagnostic criteria are not clear between both conditions and multiple symptoms could overlap. Case Presentation. The patient is an 8-year-old boy of Brazilian descent, who initially presented with a 1-year history of painful oral ulcers. Before presenting to the hospital, he had been treated for periodic fever, aphthous stomatitis, pharyngitis, and adenitis and placed on steroids, with relapsing symptoms on attempts to wean the doses. The initial workup was largely unremarkable. Buccal biopsies showed no granulomas, and the ophthalmologic exam was normal. Infectious and rheumatological tests were negative. Prometheus IBD sgi testing showed a pattern consistent with CD; however, the patient had multiple negative endoscopies, colonoscopies, and capsule endoscopies. He developed intermittent bloody stools and severe malnutrition and did not respond to infliximab, colchicine, or methotrexate. After a large GI bleed, a 4th colonoscopy was performed, which showed large round ulcers in the terminal ileum, and no granulomas. He was started on ustekinumab with clinical improvement. One month later, he developed bilateral hip effusion and meningismus, being diagnosed with aseptic meningitis secondary to COVID-19. He improved, but in one month developed worsening symptoms, and MRV showed extensive venous sinus thrombosis. The patient was started on enoxaparin, methylprednisolone, and colchicine, with resolution of the thrombus on a 3-month follow-up. The patient's overall symptoms remained controlled with clinical and biochemical remission on monthly ustekinumab. Discussion and Conclusion. Our patient had a challenging clinical course, with nonspecific systemic and intestinal manifestations which proved difficult to differentiate between BD and CD. Given endoscopic findings and the worsening of an auto-inflammatory reaction in the central nervous system after COVID-19 in a patient with controlled GI symptoms, the most likely diagnosis is BD.

Maternity service reconfigurations for intrapartum and postnatal midwifery staffing shortages: modelling of low-risk births in England.

INTRODUCTION: Choice of birth setting is important and it is valuable to know how reconfiguring available settings may affect midwifery staffing needs. COVID-19-related health system pressures have meant restriction of community births. We aimed to model the potential of service reconfigurations to offset midwifery staffing shortages. METHODS: We adapted the Birthrate Plus method to develop a tool that models the effects on intrapartum and postnatal midwifery staffing requirements of changing service configurations for low-risk births. We tested our tool on two hypothetical model trusts with different baseline configurations of hospital and community low-risk birth services, representing those most common in England, and applied it to scenarios with midwifery staffing shortages of 15%, 25% and 35%. In scenarios with midwifery staffing shortages above 15%, we modelled restricting community births in line with professional guidance on COVID-19 service reconfiguration. For shortages of 15%, we modelled expanding community births per the target of the Maternity Transformation programme. RESULTS: Expanding community births with 15% shortages required 0.0 and 0.1 whole-time equivalent more midwives in our respective trusts compared with baseline, representing 0% and 0.1% of overall staffing requirements net of shortages. Restricting home births with 25% shortages reduced midwifery staffing need by 0.1 midwives (-0.1% of staffing) and 0.3 midwives (-0.3%). Suspending community births with 35% shortages meant changes of -0.3 midwives (-0.3%) and -0.5 midwives (-0.5%) in the two trusts. Sensitivity analysis showed that our results were robust even under extreme assumptions. CONCLUSION: Our model found that reconfiguring maternity services in response to shortages has a negligible effect on intrapartum and postnatal midwifery staffing needs. Given this, with lower degrees of shortage, managers can consider increasing community birth options where there is demand. In situations of severe shortage, reconfiguration cannot recoup the shortage and managers must decide how to modify service arrangements.

Clinical efficacy of a novel radiofrequency toothbrush for tooth stain reduction and tooth whitening: A randomized controlled trial.

BACKGROUND: The authors aimed to evaluate the effect of a novel radiofrequency (RF) toothbrush on tooth stains and shades compared with a sonic vibrating toothbrush (CVS Health SmileSonic Pro Advanced Clean Sonic Toothbrush, Ranir) that earned the American Dental Association Seal of Acceptance. METHODS: The authors conducted a single-blind prospective study over 6 weeks. Participants were randomized to 1 of 2 study groups to receive either an RF toothbrush (ToothWave, Home Skinovations [test]) or a sonic vibrating toothbrush (SmileSonic powered toothbrush, Ranir [control]) and performed twice-daily toothbrushing with fluoridated toothpaste (Crest Cavity Protection, Procter & Gamble) for 6 weeks. Tooth stains and shades were assessed using the Lobene Stain Index and VITA Bleachedguide 3D-MASTER shade guide (VITA North America) at baseline and after 4 and 6 weeks of toothbrushing. In addition, the VITA Easyshade Advance 4.0 spectrophotometer (VITA North America) was used for shade evaluation. Safety was evaluated by means of oral soft-tissue examinations at each visit. Percentage reduction from baseline was compared between the groups. Statistical analyses were conducted using Mann-Whitney nonparametric model. RESULTS: Eighty-six participants (43 in each group) completed the study with fully evaluable data. At baseline, the groups did not differ significantly in mean measurement scores. Percentage reductions of the measured scores were significantly greater (more extrinsic stain removal and whitening) in the test group than in the control group (P < .001). Both toothbrushes were well-tolerated, and no device-related adverse events were reported during the study. CONCLUSIONS: The RF toothbrush produced substantial benefits in the reduction of tooth stains and whitening of tooth shade compared with a powered toothbrush (CVS Health SmileSonic Pro Advanced Clean Sonic Toothbrush, Ranir) that earned the American Dental Association Seal of Acceptance. PRACTICAL IMPLICATIONS: The novel RF toothbrush is a safe and effective tool for stain removal and tooth whitening and can serve as an alternative to other whitening agents. This clinical trial was registered at ClinicalTrials.gov. The registration number is NCT03885609.

Role of Proglucagon Peptides in Osmoregulation.

Glucagon-like peptide-1 (GLP-1), a product of partial proteolysis of proglucagon, is involved not only in regulation of carbohydrates, but also in water-salt metabolism. The study examined the role of proglucagon derivatives GLP-1, GLP-2, and oxyntomodulin in rat osmoregulation. Of them, only blood plasma GLP-1 increased in response to water load (20 ml/kg). Administration of glucose (1.5 g/kg) elevated GLP-1 and oxyntomodulin but did not change the level of GLP-2. GLP-1 accelerated excretion of excess water during hyperhydration, whereas GLP-2 decreased this parameter. No physiological effects of oxyntomodulin in the kidneys were revealed. Probably, the blood levels of proglucagon derivatives are independently regulated for each peptide. In contrast to GLP-2 and oxyntomodulin, GLP-1 is involved in osmoregulation.

The contribution of qualitative research within the PRECISE study in sub-Saharan Africa.

The PRECISE Network is a cohort study established to investigate hypertension, fetal growth restriction and stillbirth (described as "placental disorders") in Kenya, Mozambique and The Gambia. Several pregnancy or birth cohorts have been set up in low- and middle-income countries, focussed on maternal and child health. Qualitative research methods are sometimes used alongside quantitative data collection from these cohorts. Researchers affiliated with PRECISE are also planning to use qualitative methods, from the perspective of multiple subject areas. This paper provides an overview of the different ways in which qualitative research methods can contribute to achieving PRECISE's objectives, and discusses the combination of qualitative methods with quantitative cohort studies more generally.We present planned qualitative work in six subject areas (health systems, health geography, mental health, community engagement, the implementation of the TraCer tool, and respectful maternity care). Based on these plans, with reference to other cohort studies on maternal and child health, and in the context of the methodological literature on mixed methods approaches, we find that qualitative work may have several different functions in relation to cohort studies, including informing the quantitative data collection or interpretation. Researchers may also conduct qualitative work in pursuit of a complementary research agenda. The degree to which integration between qualitative and quantitative methods will be sought and achieved within PRECISE remains to be seen. Overall, we conclude that the synergies resulting from the combination of cohort studies with qualitative research are an asset to the field of maternal and child health.

The Cascade System of Osmotic Homeostasis Regulation.

The human and animal osmoregulation system is aimed at stabilizing serum osmolality in order to maintain cell volume. It has been shown that the introduction of 5 mL water per 100 g of body weight into the stomach of rats decreases serum osmolality and the concentration of Na and Ca, but not K and Mg. The cascade system of osmotic homeostasis increases secretion of glucagon-like peptide-1 (GLP-1) and oxytocin, and decreases secretion of vasopressin, which reduces the osmotic permeability of collecting duct. After water loading and the injection of 0.015 nM exenatide (GLP-1 mimetic), the time of excretion of 50% of water was halved from 112 ± 4 to 57 ± 5 min (p < 0.01), and after the injection of 0.015 nM oxytocin, it decreased to 83 ± 6 min (p < 0.01). The physiological mechanism of renal effect of the aforementioned hormones which accelerate the recovery of osmotic homeostasis has been found.

Stimulus for Glucagon-Like Peptide 1 Secretion in Rats.

Blood concentration of glucagon-like peptide-1 (GLP-1) increased 5 min after per os administration of water, sodium chloride solution, or glucose solution. Changes in blood osmolality or blood glucose level did not stimulate GLP-1 release. A method of short-term increase in the gastric capacity in rats using an inflating balloon attached to the Foley catheter was developed in order to test the hypothesis that excitation of the upper gastrointestinal tract receptors is a primary signal for the GLP-1 secretion during oral intake of the substances. Mechanical gastric distension in rats caused elevation of the blood GLP-1 concentration which was comparable to the effects of oral administration of water, sodium chloride, and glucose solutions.

Involving male partners in maternity care in Burkina Faso: a randomized controlled trial

To determine whether an intervention to involve the male partners of pregnant women in maternity care influenced care-seeking, healthy breastfeeding and contraceptive practices after childbirth in urban Burkina Faso. Methods:In a non-blinded, multicentre, parallel-group, superiority trial, 1144 women were assigned by simple randomization to two study arms: 583 entered the intervention arm and 561 entered the control arm. All women were cohabiting with a male partner and had a low-risk pregnancy. Recruitment took place at 20 to 36 weeks' gestation at five primary health centres in Bobo-Dioulasso. The intervention comprised three educational sessions: (i) an interactive group session during pregnancy with male partners only, to discuss their role; (ii) a counselling session during pregnancy for individual couples; and (iii) a postnatal couple counselling session. The control group received routine care only. We followed up participants at 3 and 8 months postpartum.Findings:The follow-up rate was over 96% at both times. In the intervention arm, 74% (432/583) of couples or men attended at least two study sessions. Attendance at two or more outpatient postnatal care consultations was more frequent in the intervention than the control group (risk difference, RD: 11.7%; 95% confidence interval, CI: 6.0 to 17.5), as was exclusive breastfeeding 3 months postpartum (RD: 11.4%; 95% CI: 5.8 to 17.2) and effective modern contraception use 8 months postpartum (RD: 6.4%; 95% CI: 0.5 to 12.3). Conclusion:Involving men as supportive partners in maternity care was associated with better adherence to recommended healthy practices after childbirth

Provider and lay perspectives on intra-uterine contraception: a global review.

BACKGROUND: Intra-uterine contraception (IUC) involves the use of an intra-uterine device (IUD), a highly effective, long-acting, reversible contraceptive method. Historically, the popularity of IUC has waxed and waned across different world regions, due to policy choices and shifts in public opinion. However, despite its advantages and cost-effectiveness for programmes, IUC's contribution to contraceptive prevalence is currently negligible in many countries. This paper presents the results of a systematic review of the global literature on provider and lay perspectives on IUC. It aims to shed light on the reasons for low use of IUC and reflect on potential opportunities for the method's promotion. METHODS: A systematic search of the literature was conducted in four peer-reviewed journals and four electronic databases (MEDLINE, EMBASE, POPLINE, and Global Health). Screening resulted in the inclusion of 68 relevant publications. RESULTS: Most included studies were conducted in areas where IUD use is moderate or low. Findings are similar across these areas. Many providers have low or uneven levels of knowledge on IUC and limited training. Many wrongly believe that IUC entails serious side effects such as pelvic inflammatory disease (PID), and are reluctant to provide it to entire eligible categories, such as HIV-positive women. There is particular resistance to providing IUC to teenagers and nulliparae. Provider opinions may be more favourable towards the hormonal IUD. Some health-care providers choose IUC for themselves. Many members of the public have low knowledge and unfounded misconceptions about IUC, such as the fear of infertility. Some are concerned about the insertion and removal processes, and about its effect on menses. However, users of IUC are generally satisfied and report a number of benefits. Peers and providers exert a strong influence on women's attitudes. CONCLUSION: Both providers and lay people have inaccurate knowledge and misconceptions about IUC, which contribute to explaining its low use. However, many reported concerns and fears could be alleviated through correct information. Concerted efforts to train providers, combined with demand creation initiatives, could therefore boost the method's popularity. Further research is needed on provider and lay perspectives on IUDs in low- and middle-income countries.

Involvement of Glucagon-Like Peptide-1 in the Regulation of Selective Excretion of Sodium or Chloride Ions by the Kidneys.

An increase of total glucagon-like peptide-1 (GLP-1) concentration in the plasma in rats was revealed 5 min after oral, but not intraperitoneal administration of NaCl or Trizma HCl solutions. The increase in GLP-1 level was similar to that after oral glucose administration. After intraperitoneal administration of 2.5% NaCl, GLP-1 mimetic exenatide accelerated natriuresis and urinary chloride excretion. Under conditions of normonatriemia and hyperchloremia induced by injection of 6.7% Trizma HCl, exenatide stimulated chloride excretion and reabsorption of sodium ions in the kidneys. These findings suggest that GLP-1 participates in selective regulation of the balance of sodium and chloride ions.

Expanding Method Choice in Africa with Long-Acting Methods: IUDs, Implants or Both?

The objective of this article is to review key components of LARC uptake in Sub-Saharan Africa with the aim of guiding policies and programs. We assess trends in access to the IUD and implant, including method knowledge and availability at facilities; examine trends in use, source of supply, discontinuation and characteristics of users; and discuss the prospects for expanding method choice by increasing the availability of LARCs in national programs and the policy implications of our results.

The mechanism of glucagon-like peptide-1 participation in the osmotic homeostasis.

We have found the physiological mechanism of intensification of the excessive fluid removal from the body under the action of glucagon-like peptide-1 and its analog exenatide. Under the water load in rats, exenatide significantly increased the clearance of lithium, reduced fluid reabsorption in the proximal tubule of the nephron and intensified reabsorption of sodium ions in the distal parts, which contributed to the formation of sodium-free water and faster recovery of osmotic homeostasis. Blocking this pathway with a selective antagonist of glucagon-like peptide-1 receptors slowed down the elimination of excessive water from the body.

Effects of Selective Agonists of V1a, V2, and V1b Receptors on Sodium Transport in Rat Kidney.

The role of subtypes of vasopressin receptors in modulation of renal sodium reabsorption was studied in in vivo experiments on Wistar rats. Selective V1a receptor agonist reduced sodium reabsorption in the kidneys and expression of these receptors increased by practically 100 times. This effect was similar to the effect of furosemide. Selective V2 receptor agonist enhanced sodium reabsorption in the kidney and simultaneously increased reabsorption of solute-free water. Stimulation of V1b receptors did not affect sodium transport. Our findings attest to the key role of V1a receptors in the regulation of renal excretion of sodium ions.

Role of Vasopressin in the Regulation of Renal Sodium Excretion: Interaction with Glucagon-Like Peptide-1.

The present study aimed to investigate the potential physiological role of vasopressin and the incretin hormone of the gastrointestinal tract (glucagon-like peptide-1; GLP-1) in the regulation of the water-salt balance in a hyperosmolar state as a result of sodium loadings. In rats, the administration of hypertonic NaCl solution resulted in a significant increase in natriuresis, which correlated with the vasopressin excretion rate. Natriuresis following an i.p. NaCl load (23.2 ± 1.4 µmol/min/kg) was enhanced by inhibition of V2 receptors (51.6 ± 3.7 µmol/min/kg, P < 0.05) and was reduced by a V1a antagonist injection (6.3 ± 1.1 µmol/min/kg, P < 0.05). Compared to i.p. salt administration, oral NaCl loading induced a significant increase in the plasma GLP-1 level within 5 min and resulted in more prominent natriuresis and a smaller increase in blood sodium concentration. It was hypothesised that the basis for the fast elimination of excess sodium following an oral NaCl load could be the involvement of GLP-1 in osmoregulation combined with vasopressin. It was demonstrated that GLP-1 mimetic exenatide (1.5 nmol/kg) produced a significant decrease in proximal reabsorption and an increase in fractional sodium excretion (from 0.15 ± 0.04% to 9 ± 1%). It was also shown that vasopressin at doses of 1-10 µg/kg and the selective V1a agonist (1 µg/kg) induced an increase in sodium fractional excretion to 10 ± 2% and 8 ± 2%, respectively. Combined administration of exenatide and V1a agonist revealed their cumulative natriuretic effect, and sodium fractional excretion increased by up to 18 ± 2%. These data suggest that GLP-1 combined with vasopressin could be involved in the regulation of sodium balance in the hyperosmolar state as a result of NaCl loading. Vasopressin regulates the reabsorption of a significant portion of filtered sodium in the distal segment of the nephron and modulates the natriuretic effect of GLP-1.

[EFFECTS OF ORALLY AND PARENTERALLY ADMINISTERED ANALOGS OF PEPTIDE HORMONES ON RENAL WATER AND ION TRANSPORT].

In experiments with female Wistar rats it was shown that analogs of neurohypophysial hormones administered to gastrointestinal tract preserved their specific physiological activity - they increased solute-free water reabsorption and urinary sodium and potassium excretion. Doses of deamino-vasotocin exerted antidiuretic and natriuretic effects following its oral administration were 50 and 200 times higher compared to maximal effective ones after intramuscular injection. Inhibition of gastrointestinal proteases by aprotinine enhanced effects of nonapeptides; the amount of peptide absorbed from the intestine under these conditions was approximately 0.5 % of orally introduced substance. In contrast to analogs of neurohypophysial nonapeptides, glucagon-like peptide-1 mimetic (exenatide) did not exert its physiological effects after oral administration, whereas it increased urinary sodium and potassium excretion following intramuscular injection.

[DIFFERENCES OF EXENATIDE EFFECTS ON GLYCEMIA AND RENAL WATER AND ION EXCRETION IN FROGS AND RATS].

The aim of the present study was to compare effects of glucagon-like peptide-1 (GLP-1) mimetic exenatide on glucose and water-salt homeostasis in animals with different level of renal tubular proximal reabsorption - rats (Rattus norvegicus) and frogs (Rana temporaria). Following glucose tolerance test, in rats exenatide promoted rapid recovery of normoglycemia, whereas in frogs delayed this process. In water-loaded rats exenatide essentially augmented solute-free water clearance and enhanced natriuresis in furosemide-treated rats.-In frogs exenatide did not alter urinary flow rate, urinary sodium excretion and solute-free water clearance under water diuresis and furosemide treatment. It is suggested that the invol- vement of GLP- 1 in regulation of water-salt homeostasis in mammals should be preceded by key evoluti- onary transformation - increase in glomerular filtration rate and proximal tubular reabsorption.

Redistribution of Proximal and Distal Reabsorption of Water and Ions in Rat Kidney After Treatment with Glucagon-Like Peptide-1 Mimetic.

Injection of a glucagon-like peptide-1 mimetic accelerated recovery of the initial status of water-salt balance in rats after water or saline load (2.5% NaCl). This effect is mediated by a decrease in proximal fluid reabsorption and change in ion and water transport in the distal part of renal tubules. We developed a new approach to calculation of additional fluid inflow from the proximal tubule to the distal tubule and distal sodium reabsorption under the influence of this mimetic in rats. The expected values corresponded to experimental results, which confirmed our hypothesis on the physiological mechanism for the involvement of the kidneys in the homeostatic effect of glucagon-like peptide-1 under variations in water-salt balance.

[PHYSIOLOGICAL APPROACH TO RESTORING OSMOTIC HOMEOSTASIS IN RATS WITH HYPERNATREMIA].

The aim of the study was a search of physiological approach to restoring osmotic homeostasis in rats with hypernatremia. Intraperitoneal administration of 1.8 ml/100 g BW 2.5% NaCl solution to Wistar rats induced hyperosmia (306 +/- 1 mOsm/kg H2O) and hypernatremia (150.3 +/- 0.3 mM in 60 min of experiment), increase in urinary sodium excretion (from 8 +/- 1 to 230 +/- 10 micromol/100 g BW for 2 h). Under these conditions enhancement of natriuresis up to 465 +/- 29 micromol/100 g BW and 667 +/- 24 micromol/100 g BW for 2 h was observed after injections of vasopressin analogue, deamino-vasotocin (dAVT, 0.05 microg/100 g BW), or loop diuretic, furosemide (1 mg/100 g BW), respectively. dAVT-induced natriuresis was accompanied by increase in solute-free water reabsorption; serum osmolality (301 +/- 1 mOsm/kg H2O) and sodium concentration (145.8 +/- 0.5 mM) were close to normal values by 60 min of experiment. Furosemide caused relatively greater excretion of water, than sodium; hypernatremia (150.2 +/- 0.4 mM) and hyperosmia (311 +/- 1 mOsm/kg H2O) persisted during 60 min of experiment. Thus, in rats with hypernatremia dAVT due to decrease in renal sodium reabsorption and increase in solute-free water reabsorption promotes recovery of serum osmolality and sodium concentration.
