Posterior Tibial Nerve Stimulation in Children with Lower Urinary Tract Dysfunction: A Mixed-Methods Analysis of Experiences, Quality of Life and Treatment Effect.

BACKGROUND: Posterior tibial nerve stimulation (PTNS) is one of the treatment modalities for children with therapy-refractory lower urinary tract dysfunction (LUTD). This study used a mixed-methods analysis to gain insight into the experiences of children treated with PTNS and their parents, the effect of treatment on quality of life (QOL) and the effect of PTNS on urinary symptoms. METHODS: Quantitative outcomes were assessed through a single-centre retrospective chart analysis of all children treated with PTNS in a group setting between 2016-2021. Voiding parameters and QOL scores before and after treatment were compared. Qualitative outcomes were assessed by an explorative study involving semi-structured interviews transcribed verbatim and inductively analysed using the constant-comparative method. RESULTS: The data of 101 children treated with PTNS were analysed. Overall improvement of LUTD was seen in 42% and complete resolution in 10%. Average and maximum voided volumes significantly increased. QOL improved in both parents and children independent of the actual effect on urinary symptoms. Interviews revealed PTNS to be well-tolerated. Facilitating PTNS in a group setting led to feelings of recognition in both children and parents. CONCLUSIONS: PTNS is a good treatment in children with therapy-refractory LUTD and provides valuable opportunities for peer support if given in a group setting.

Care avoidance among homeless people and access to care: an interview study among spiritual caregivers, street pastors, homeless outreach workers and formerly homeless people.

BACKGROUND: Because of their poor health and social vulnerability, homeless people require specific care. However, due to care avoidance, homeless people are often not involved in care. This study aims to get insights into reasons for and kinds of care avoidance among homeless people and to provide suggestions to reach this target group. METHODS: Semi-structured individual interviews were conducted among street pastors (n = 9), spiritual caregivers (n = 9), homeless outreach workers (n = 7) and formerly homeless people (n = 3). Participants were recruited by purposive sampling in the four major cities in the Netherlands (Amsterdam, Utrecht, Rotterdam, The Hague). The verbatim transcripts were analysed using thematic analysis. RESULTS: The term care avoidance was perceived as stigmatizing. Care avoidance is found to be related to characteristics of the homeless person (e.g. having complex problems, other priorities) as well as of the system (e.g. complex system, conditions and requirements of organizations). The person-related characteristics suggestions to involve homeless persons include tailoring care and building relationships, which might even be prioritised over starting care interventions. Setting limits on behaviour without rejecting the person, and an attitude reflecting humanity, dignity and equality were also important factors in making care more accessible and lasting. As regards system-related characteristics, the suggestions include clear information and communication to homeless people who avoid care as being crucial in order to make care more accessible. Other suggestions include quiet and less busy shelters, a non-threatening attitude and treatment by professionals, self-reflection by professionals and finally a change of policy and legislation regarding available time. CONCLUSIONS: Reasons for care avoidance can be found in the interplay between both the individual and the system; measures to reduce care avoidance should be taken at both levels. These measures are centred on lowering the barriers to care inter alia by incorporating building trust and understanding into the care provided.

Attractiveness of people-centred and integrated Dutch Home Care: A nationwide survey among nurses.

The World Health Organization is calling for a fundamental change in healthcare services delivery, towards people-centred and integrated health services. This includes providing integrated care around people's needs that is effectively co-ordinated across providers and co-produced by professionals, the patient, the family and the community. At the same time, healthcare policies aim to scale back hospital and residential care in favour of home care. This is one reason for the home-care nursing staff shortages in Europe. Therefore, this study aimed to examine whether people-centred, integrated home care appeals to nurses with different levels of education in home care and hospitals. A questionnaire survey was held among registered nurses in Dutch home-care organisations and hospitals in 2015. The questionnaire addressed the perceived attractiveness of different aspects of people-centred, integrated home care. In total 328 nurses filled in the questionnaire (54% response rate). The findings showed that most home-care nurses (70% to 97%) and 36% to 76% of the hospital nurses regard the different aspects of people-centred, integrated home care as attractive. Specific aspects that home-care nurses find attractive are promoting the patient's self-reliance and having a network in the community. Hospital nurses are mainly attracted to health-related prevention and taking control in complex situations. No clear differences between the educational levels were found. It is concluded that most home-care nurses and a minority of hospital nurses feel attracted to people-centred, integrated home care, irrespective of their educational level. The findings are relevant to policy makers and home-care organisations who aim to expand the home-care nursing workforce.

Thyroid hormone transporters and deiodinases in the developing human hypothalamus.

OBJECTIVE: Thyroid hormone (TH) signaling in brain cells is dependent on transport of TH across the plasma membrane followed by intracellular deiodination and binding to the nuclear TH receptors. The aim of this study is to investigate the expression of the specific TH transporters monocarboxylate transporter 8 (MCT8 (SLC16A2)), MCT10, organic anion transporting polypeptide 1C1 (OATP1C1 (SLCO1C1)), and the types 2 and 3 deiodinases (D2 and D3) in the developing human hypothalamus. DESIGN: Fifteen postmortem brain samples of fetuses and young children ranging between 17 weeks of gestation and 29 months of postnatal age including one child (28 months) with central congenital hypothyroidism were studied. METHODS: Sections of the different hypothalami were stained with polyclonal rabbit antisera against MCT8, MCT10, OATP1C1, D2, and D3. RESULTS: We found MCT8 and D3 but not D2 protein expression to be present in our earliest sample of 17 weeks of gestation, indicating triiodothyronine degradation, but not production at this time of development. At term, expression of TH transporters and D2 decreased and D3 expression increased, suggesting decreased TH signaling just before birth. The child with central congenital hypothyroidism showed higher MCT8 and D2 expression compared with the other children of similar age. CONCLUSIONS: This study reports the developmental timing of expression of components crucial for central TH signaling in the human hypothalamus. In general, during fetal hypothalamic development, the coordinated expression of D2 and D3 in combination with the different TH transporters suggests that proper TH concentrations are regulated to prevent untimely maturation of brain cells.

Hypothalamic neuropeptide Y (NPY) controls hepatic VLDL-triglyceride secretion in rats via the sympathetic nervous system.

Excessive secretion of triglyceride-rich very low-density lipoproteins (VLDL-TG) contributes to diabetic dyslipidemia. Earlier studies have indicated a possible role for the hypothalamus and autonomic nervous system in the regulation of VLDL-TG. In the current study, we investigated whether the autonomic nervous system and hypothalamic neuropeptide Y (NPY) release during fasting regulates hepatic VLDL-TG secretion. We report that, in fasted rats, an intact hypothalamic arcuate nucleus and hepatic sympathetic innervation are necessary to maintain VLDL-TG secretion. Furthermore, the hepatic sympathetic innervation is necessary to mediate the stimulatory effect of intracerebroventricular administration of NPY on VLDL-TG secretion. Since the intracerebroventricular administration of NPY increases VLDL-TG secretion by the liver without affecting lipolysis, its effect on lipid metabolism appears to be selective to the liver. Together, our findings indicate that the increased release of NPY during fasting stimulates the sympathetic nervous system to maintain VLDL-TG secretion at a postprandial level.

Kavalactones fail to inhibit alcohol dehydrogenase in vitro.

In recent years, Kava kava (Piper methysticum, Forst. f., Piperaceae), a folkloric beverage and popular herbal remedy, has been implicated in a number of liver failure cases. Many hypotheses as to the mechanism of its hepatotoxicity, for example interactions with other co-ingested medication, have been postulated. This present study investigated whether pharmacokinetic interactions between kava constituents and alcohol via alcohol dehydrogenase (ADH) inhibition by individual kavalactones might explain its claimed hepatotoxic effects. Four kavalactones, (+/-)-kavain, methysticin, yangonin and desmethoxyyangonin, fail to inhibit ADH in vitro at 1, 10 or 100 microM concentrations.
