RESUMO

BACKGROUND: The Safe Environment for Every Kid (SEEK) model was developed to address psychosocial risk factors (financial worries, depressive symptoms, major parental stress, alcohol misuse and intimate partner violence) in the pediatric primary care setting but has not been evaluated from the parents' perspective. To further investigate the usefulness of SEEK, it is important to explore how parents perceive the model. OBJECTIVE: The aim of the present study was to explore parents' perceptions of the SEEK model as a part of regular health visits in the Child Health Services in Sweden. PARTICIPANTS AND SETTING: Eighteen parents (13 women and five men) in two Swedish counties participated in the study. METHODS: Semi-structured telephone interviews were conducted, and the resulting data were analyzed using reflective thematic analysis. RESULTS: Three themes were identified: Acceptance and understanding of the SEEK model in the child health services, The questionnaire as a bridge to a dialogue, and Feeling trust in the system and the child health nurse's professional competence. Further, an overarching theme was created that encompassed a core meaning of all three themes; SEEK provides a process-oriented framework to receive support in parenting with a focus on child health. CONCLUSIONS: The study showed that parents express both acceptance and understanding of the SEEK model and they perceive that the model provides an avenue for repeated dialogues about the family's situation during the child's upbringing and an opportunity to access support if needed.

RESUMO

PURPOSE: Chronic radiation cystitis (CRC) develops after radiation therapy and can present with symptoms like urinary frequency, urgency, pelvic pain, and nocturia. We have previously reported that amniotic bladder therapy (ABT) provides symptomatic improvement in refractory CRC patients for up to 3 months. Herein, we evaluated the durability of ABT up to 6 months. MATERIALS AND METHODS: CRC patients recalcitrant to previous treatments received ABT comprised of intra-detrusor injections of 100 mg micronized AM diluted in 10 mL 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder (OAB) Assessment Tool, SF-12 Health Survey) were repeated at pre-op and 2, 4, 8, 12, 16, 20, 24, and 36 weeks post-injection. RESULTS: Five consecutive patients with a mean age of 64.4 ± 20.1 years with a median CRC duration of 10 years were included and followed for 6 months. After ABT, the lower urinary tract symptoms improved as early as 2 weeks and were maintained up to 20 weeks. BPIC significantly improved from 36.6 ± 1.1 at baseline to 12.6 ± 1.5 at 16 weeks and 13.8 ± 2.9 at 20 weeks. At 24 and 36 weeks, the improvement was maintained in four (80%) of the five patients (BPIC = 13.8 ± 1.0). Uroflow assessment showed voiding volume improved two-fold in four of the five patients at 24 weeks compared to baseline. CONCLUSION: Our data suggest that a significant number of CRC patients may have durable benefit after ABT. Despite this, some of them can show symptoms rebound at 24 weeks.

RESUMO

Successful prevention of physical child abuse is dependent on improvements in risk assessment. The risk of abuse is assumed to increase when family stressors overcome resources. Severe physical disease can increase stress, and parental physical disease has been studied as a risk factor for physical child abuse, but with heterogeneous definitions. This study evaluated the relation between parental physical disease severity and severe documented physical child abuse. Models were based on data on children aged 0-17 years in Denmark between 1997 and 2018, and their parents. Severe documented physical child abuse was modeled as violence against a child registered by either health authorities in treatment or mortality registries, or police authorities in cases confirmed by the courts. Parental physical disease severity was modeled as the sum of Charlson Comorbidity Index scores for the child's parents. The causal connection was examined in two model types: a survival model comparing exposed with non-exposed children, adjusted for covariates at baseline, and a G-model, taking time-varying covariates, including income and parental psychiatric disease into account. Neither model showed an association between parental physical disease severity and severe documented physical child abuse, with RR 0.99 and 95% CI (0.93-1.05) for the survival model and RR 1.08 for the G-model (CI not calculated).  Conclusion: In the model studied, parental physical disease severity was not a risk factor for severe documented physical child abuse. Individual categories of physical disease remain to be examined.  Trial registration: The study was pre-registered on Open Science Framework, https://osf.io/fh2sr . What is Known: • Parental physical disease severity has been studied previously as a risk indicator of physical child abuse, but based on heterogeneous definitions. • Previous studies have not studied parental physical disease severity preceding physical child abuse. What is New: • Parental severe physical disease was not prospectively associated with severe documented physical child abuse in a survival model, a G-model and a number of sensitivity analyses, respectively. • Results should be replicated in samples from populations without universal health care, and using different categories of disease.

RESUMO

Improved prediction of physical child abuse could aid in developing preventive measures. Parental physical disease has been tested previously as a predictor of documented physical child abuse but in broad categories and with differing results. No prior studies have tested clinically recognizable categories of parental disease in a high-powered dataset. Using Danish registries, data on children and their parents from the years 1997-2018 were used to explore several parental physical disease categories' associations with documented physical child abuse. For each disease category, survival analysis using pseudovalues was applied. When a parent of a child was diagnosed or received medication that qualified for a category, this family and five comparison families not in this disease category were included, creating separate cohorts for each category of disease. Multiple analyses used samples drawn from 2,705,770 children. Estimates were produced for 32 categories of physical diseases. Using Bonferroni-corrected confidence intervals (CIc), ischemic heart disease showed a relative risk (RR) of 1.44 (CIc 1.13-1.84); peripheral artery occlusive disease, RR 1.39 (CIc 1.01-1.90); stroke, RR 1.19 (1.01-1.41); chronic pulmonary disease, RR 1.33 (CIc 1.18-1.51); ulcer/chronic gastritis, RR 1.27 (CIc 1.08-1.49); painful condition, 1.17 (CIc 1.00-1.37); epilepsy, RR 1.24 (CIc 1.00-1.52); and unspecific somatic symptoms, RR 1.37 (CIc 1.21-1.55). Unspecific somatic symptoms were present in 71.87% of families at some point during the study period. CONCLUSION: Most parental physical disease categories did not show statistically significant associations, but some showed predictive ability. Further research is needed to explore preventive potential. WHAT IS KNOWN: • Few and broad categories of parental physical disease have been examined as risk factors for severe physical child abuse; no prior study has used several categories as predictors. WHAT IS NEW: • Unspecific symptoms, ischemic heart disease, peripheral artery occlusive disease, stroke, chronic pulmonary disease, stomach ulcer/chronic gastritis, painful condition, and epilepsy all showed to be potential predictors, with unspecific symptoms being the most prevalent.

RESUMO

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 virus is an international health concern with substantial morbidity and mortality. COVID-associated cystitis (CAC), presents as new onset or exacerbated urinary symptoms, resembling overactive bladder (OAB) symptoms. AIM: To examines the long-term outcomes of patients with CAC in the context of Long COVID. METHODS: A cohort of 350 patients admitted to Detroit Hospitals with COVID-19 between May and December 2020, displaying CAC symptoms following discharge, was prospectively followed. Initial urologic evaluations occurred at 10-14 wk and were repeated at 21-28 mo post-discharge. Symptoms were managed conservatively, employing behavioral modifications and standard OAB medications. Participants completed surveys assessing urinary symptoms and quality of life (QoL) at both time points. The primary outcome was the Urology Care Foundation Overactive Bladder Assessment Tool. RESULTS: 87% of the final cohort (n = 310) reported symptom improvement at 21-28 mo post-discharge. Patients with new onset CAC symptoms showed a median decrease of 9-10 points in OAB and QoL scores, while those with existing symptoms experienced a decrease of 6 points. Overall, 95.4% of patients with new onset symptoms reported symptom improvement at follow-up, contrasting with 60.7% among those with existing symptoms. CONCLUSION: This study presents the first long-term follow-up of adult patients with CAC, revealing a promising prognosis with conservative management measures in the context of Long COVID. These findings provide reassurance to patients regarding symptom resolution and underscore the need for further research into this evolving aspect of COVID-19's impact on urological health.

RESUMO

BACKGROUND: Psychosocial risk factors in the home may impair children's health and development and increase the risk of maltreatment. The Safe Environment for Every Kid (SEEK) model was developed to provide pediatric primary care professionals with a structured way to identify common psychosocial problems. The SEEK model includes use of the Parent Screening Questionnaire (SEEK-PSQ) at routine preventive child health visits, discussion with parents about their responses and, when indicated, referral to relevant services. The SEEK-PSQ has not previously been available in Swedish. The aim of the present study was to evaluate the psychometric properties of an adapted Swedish version of the SEEK-PSQ (PSQ-S). METHODS: This study is part of a cluster-randomised controlled trial of SEEK in the Swedish child health services. To validate the PSQ-S, parents (n = 852) with children 0-18 months of age were invited to complete a survey including the PSQ-S as well as evidence-based standardized instruments for the targeted psychosocial risk factors: economic worries, depressive symptoms, parental stress, alcohol misuse and intimate partner violence (IPV). Baseline data from 611 (72%) parents were analysed regarding sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for each risk factor. RESULTS: As a whole, the PSQ-S had a sensitivity of 93%, specificity of 52%, PPV of 67% and NPV of 87%. For mothers and fathers combined, sensitivity was 80% for economic worries, 89% for depressive symptoms, 78% for parental stress, 47% for intimate partner violence (IPV) and 70% for alcohol misuse. Specificity was highest for IPV and alcohol misuse (91%) and lowest for depressive symptoms (64%). NPV values were high (81-99%) and PPV values were low to moderate (22-69%) for the targeted problems. Sensitivity was higher for mothers compared to fathers for economic worries, depressive symptoms and IPV. This difference was particularly evident for IPV (52% for mothers, 27% for fathers). CONCLUSION: The SEEK-PSQ-S demonstrated good psychometric properties for identifying economic worries, depressive symptoms, parental stress and alcohol misuse but low sensitivity for IPV. The PSQ-S as a whole showed high sensitivity and NPV, indicating that most parents with or without the targeted psychosocial risk factors were correctly identified. TRIAL REGISTRATION: ISRCTN registry, study record 14,429,952 ( https://doi.org/10.1186/ISRCTN14429952 ) Registration date 27/05/2020.

RESUMO

BACKGROUND: Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by symptomatic frequency and urgency, as well as chronic pelvic pain. Disruption of the urothelial barrier is closely associated with IC/BPS. As amniotic membranes (AM) offer capabilities of wound healing in many other fields of medicine, likewise amniotic bladder therapy (ABT) may offer capability of urothelial healing in IC/BPS. METHODS: Under general anesthesia, 10 consecutive IC/BPS patients received intra-detrusor injections of 100 mg micronized AM (Clarix Flo) diluted in 10 ml 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/ Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder Assessment Tool, and SF-12 Health Survey) were repeated at pre-op and 2, 4, 8 and 12 weeks post-op. RESULTS: Ten females (47.4 ± 14.4 years) who had recalcitrant IC/BPS for 7.8 years (5.2-12.1 years) received injection of micronized AM uneventful in all cases. After treatment, voiding symptoms and bladder pain significantly improved from pre-injection to 3 months. BPIC-SS significantly decreased from 37.4 ± 0.70 at baseline to 12.2 ± 2.90 at 3 months (p < 0.001). This corresponded to a significant improvement in their overall physical and mental quality of life. No adverse events occurred related to micronized AM injections, such as UTIs or acute urinary retention. CONCLUSION: ABT could be an innovative treatment option for IC/BPS patients in terms of improving clinical symptoms based on preliminary outcomes at 3 months. Further studies are warranted to confirm the usefulness of ABT in patients with IC/BPS and to determine the duration of the effect.

RESUMO

BACKGROUND: Child maltreatment (CM) is often hidden, and the youngest children are often those most exposed. CM can be prevented through programs that address risk factors, but few primary prevention strategies have been evaluated. OBJECTIVE: To examine the experiences of nurses using the Safe Environment for Every Kid (SEEK) model compared to nurses using current standard practice in the Swedish child health services (CHS) to address psychosocial risk factors in the family environment. PARTICIPANTS AND SETTING: Nurses at 27 child health centers in the CHS in the county of Dalarna, Sweden participated in the study. A survey was answered by 55 nurses and 18 nurses participated in focus-group interviews. METHODS: A convergent mixed methods research design with focus-group interviews and survey data was used. Qualitative Content Analysis was used to analyze the interview data and Mann Whitney U test was used to analyze the survey data. RESULTS: The qualitative analysis identified four categories - "Framing the prerequisites for successful practice"; "Managing the mission of the CHS"; "Meeting the family as a professional"; and "Working with psychosocial risk factors can be emotional" - under the overarching theme "Universal application of a structured method adds value to experience-based knowledge when addressing psychosocial risk factors". Survey data showed that SEEK nurses rated to a greater degree that they possessed adequate knowledge, competence and sense of security to address psychosocial risk factors in their work. CONCLUSIONS: This study indicates that using SEEK can strengthen the nurses in identifying and responding to families in need of psychosocial support.

RESUMO

The unique attributes of very-long-chain polyunsaturated fatty acids (VLC-PUFAs), their long carbon chains (n > 24) and high degree of unsaturation, impart unique chemical and physical properties to this class of fatty acids. The changes imparted by VLC-PUFA 32:6 n-3 on lipid packing and the compression moduli of model membranes were evaluated from π-A isotherms of VLC-PUFA in 1,2-distearoyl-sn-3-glycero-phosphocholine (DSPC) lipid monolayers. To compare the attractive or repulsive forces between VLC-PUFA and DSPC lipid monolayers, the measured mean molecular areas (MMAs) were compared with the calculated MMAs of an ideal mixture of VLC-PUFA and DSPC. The presence of 0.1, 1, and 10 mol % VLC-PUFA shifted the π-A isotherm to higher MMAs of the lipids comprising the membrane and the observed positive deviations from ideal behavior of the mixed VLC-PUFA:DSPC monolayers correspond to repulsive forces between VLC-PUFAs and DSPC. The MMA of the VLC-PUFA component was estimated using the measured MMAs of DSPC of 47.1 ± 0.7 Å2/molecule, to be 15,000, 1100, and 91 Å2/molecule at 0.1, 1, and 10 mol % VLC-PUFA:DSPC mixtures, respectively. The large MMAs of VLC-PUFA suggest that the docosahexaenoic acid tail reinserts into the membrane and adopts a nonlinear structure in the membrane, which is most pronounced at 0.1 mol % VLC-PUFA. The presence of 0.1 mol % VLC-PUFA:DSPC also significantly increased the compression modulus of the membrane by 28 mN/m compared with a pure DSPC membrane. The influence of VLC-PUFA on lipid "flip-flop" was investigated by sum-frequency vibrational spectroscopy. The incorporation of 0.1 mol % VLC-PUFA increased the DSPC flip-flop rate fourfold. The fact that VLC-PUFA promotes lipid translocation is noteworthy as retinal membranes require a high influx of retinoids which may be facilitated by lipid flip-flop.

RESUMO

BACKGROUND: In situ metabolism of ethanol by alcohol dehydrogenases (ADHs) contributes to oxidative damage of cells and DNA and has been linked to carcinogenesis in numerous epithelial tissues. The goal of this study was to determine expression patterns of ADH1 and ADH7 isozymes in normal, hyperplastic (benign prostatic hyperplasia [BPH]) and neoplastic (prostate cancer [PCa]) prostate. Furthermore, racial differences in ADH expression between African Americans and Caucasians were investigated. METHODS: ADH expression patterns were characterized by density analysis of ADH immunohistochemistry (n = 21) and real-time RT-PCR of total RNAs by laser-capture microdissection (n = 10) and whole tissue formalin-fixed paraffin embedded prostate biopsies (n = 63). RESULTS: ADH protein is found in normal prostate and is primarily associated with glandular epithelium. Transcripts of ADH1B are suppressed in PCa compared to BPH (p = 0.0095). Racial differences in ADH7 transcripts exist between African American and Caucasian men. A total of 57.6% of biopsies from African American prostates have detectable ADH7 messenger RNA (mRNA) transcripts compared to the 13.3% of Caucasian prostate biopsies with detectable transcripts (p = 0.0005). This increased frequency of detection contributes to higher mean ADH7 mRNA transcript levels in African Americans (p = 0.001). CONCLUSIONS: To our knowledge this study is the first to report downregulation of ADH1B in neoplastic prostate at the transcriptional level, suggesting protective regulatory functions. ADH7 transcripts were not detectable in all samples and was found in higher frequency and amount in our African American samples. Racial differences in ADH7 within the prostate is a novel finding and should be investigated further.

RESUMO

AIMS: The aim of the present study was to examine the prevalence of childhood experiences of physical violence (CPV) and emotional violence (CEV) at the hands of parents over a 57-year period among adults born between 1937 and 1993. METHODS: In 2012, a survey among women and men aged 18-74 years in Sweden was undertaken to examine the lifetime prevalence of physical, psychological and sexual violence and associations with current health in adulthood. Questionnaires were based on the Adverse Childhood Experiences study and a previous national survey of violence exposure. Descriptive statistics were used to analyse the frequency of exposure to CPV and CEV, and changes over time were analysed using analysis of variance and logistic regression. RESULTS: A total of 10,337 individuals participated (response rates: 56% for women and 48% for men). CPV decreased significantly over the time period studied, particularly for those born after 1983. This decrease was more evident for male respondents. Throughout the time period studied, the proportion of women reporting CEV was higher than for men. Among both genders there was a steady rise in CEV rates from those born in the late 1930s to those born in the mid-1980s, after which there was a decline that was more marked for men. CONCLUSIONS: A significant group of children in Sweden experience violence at the hands of parents. However, our data corroborate previous national studies that children's exposure to violence has decreased. Clear gender differences indicate that these changes have affected girls and boys differently.

RESUMO

In this case report, we present the rare complication of proximal migration of ureteral stent after kidney transplant, and we describe our approach for its diagnosis and treatment. Although endoscopic management is the treatment of choice for retrieval of migrated stents, we reexplored the transplant in response to erroneous reporting of ureteral stent lying in an extravesicular position on a pelvic computed tomography scan. Subsequent exploration disproved the original interpretation of the image. Proximal stent migration may result from retrograde peristalsis and is generally related to suboptimal stent length.

RESUMO

Rare, nondietary very-long-chain polyunsaturated fatty acids (VLC-PUFAs) are uniquely found in the retina and a few other vertebrate tissues. These special fatty acids play a clinically significant role in retinal degeneration and development, but their physiological and interventional research has been hampered because pure VLC-PUFAs are scarce. We hypothesize that if Stargardt-3 or age-related macular degeneration patients were to consume an adequate amount of VLC-PUFAs that could be directly used in the retina, it may be possible to bypass the steps of lipid elongation mediated by the retina's ELOVL4 enzyme and to delay or prevent degeneration. We report the synthesis of a VLC-PUFA (32:6 n-3) in sufficient quantity to study its bioavailability and functional benefits in the mouse retina. We acutely and chronically gavage fed wild-type mice and Elovl4 rod-cone conditional knockout mice this synthetic VLC-PUFA to understand its bioavailability and its role in visual function. VLC-PUFA-fed wild-type and Elovl4 conditional knockout mice show a significant increase in retinal VLC-PUFA levels in comparison to controls. The VLC-PUFA-fed mice also had improvement in the animals' visual acuity and electroretinography measurements. Further studies with synthetic VLC-PUFAs will continue to expand our understanding of the physiological roles of these unique retinal lipids, particularly with respect to their potential utility for the treatment and prevention of retinal degenerative diseases.

RESUMO

Aims: The aims of this cross-sectional study were to examine the prevalence of lifetime exposure to sexual, physical and psychological violence among a representative sample of women and men in Sweden, and to analyze if there were gender differences regarding the types of violence the participants were exposed to and by whom it was perpetrated. Methods: A survey containing questions about lifetime experiences of sexual, physical and psychological violence was sent to a national sample of 10,000 women and 10,000 men aged 18-74; 56.8% of the women and 46.5% of the men agreed to participate. Results: Sexual violence in childhood was reported by 26.4% of women and 22.1% experienced sexual violence in adulthood. Among men, 11% disclosed experiences of sexual violence in childhood and 4.5% in adulthood. Physical violence was experienced by 39.3% of women in childhood and by 18.8% as adults, often by a present or former partner. Among men, 59.3% were exposed to physical violence during childhood, often by a peer, and 20.4% as adults. Psychological violence in childhood was experienced by 58.1% of women in childhood and by 21.8% in adulthood. Among male respondents, 69.2% reported experiences of physiological violence in childhood, often by a peer, and 9.4% in adulthood. Conclusions: Lifetime violence exposure is common in the Swedish population. Though it affects both women and men, the patterns of type of violence and perpetrators are different. The results suggest that violence prevention early in life is important to target.

RESUMO

Aims: This cross-sectional, population-based study aimed to investigate the prevalence of violence polyvictimization during childhood and sexual violence in adulthood among women, and how childhood violence exposure and sociodemographic factors associate with women's risk of experiencing sexual violence in adulthood. Methods: A survey regarding lifetime experiences of sexual, physical and psychological violence was sent to a national sample of 10,000 women aged 18-74 years, of which 56% participated. Data were analysed using Chi-square analyses and logistic regression. Results: Sexual violence before 18 years of age was reported by 16.3% and rape/attempted rape in adulthood by 10.2% of the women. In univariate analyses, sexual, physical, and psychological violence during childhood was associated with rape/attempted rape in adulthood (odds ratio 4.5, confidence interval 3.2-6.2; odds ratio 2.5, confidence interval 1.3-4.6; and odds ratio 2.5, confidence interval 1.8-3.2, respectively). Associations were stronger for combined exposure to sexual and physical (odds ratio 5.5, confidence interval 2.5-12.3), sexual and psychological (odds ratio 9.2, confidence interval 6.7-12.8) or sexual, physical, and psychological violence (odds ratio 14.1, confidence interval 10.4-19.2) during childhood. Rape/attempted rape after 18 years of age was more common among women who were single, those with college-level education and those who had been unemployed or had received social welfare payments. Most associations remained relatively unchanged when including all exposure and background variables in multivariate analyses. Conclusions: Although several of the sociodemographic factors studied showed significant associations, multiple exposure to violence during childhood was found to be the most potent risk factor for sexual violence in adulthood among adult women.
