Interaction between serum FGF-23 and PTH in renal phosphate excretion, a case-control study in hypoparathyroid patients
Authors: Saki Forough , Kassaee Seyed Reza , Salehifar Azita , Omrani Gholam Hossein Ranjbar
Published: May 2020

Background

phosphate homeostasis is mediated through complex counter regulatory feed-back balance between parathyroid hormone, FGF-23 and 1,25(OH)2D. Both parathyroid hormone and FGF-23 regulate proximal tubular phosphate excretion through signaling on sodium- phosphate cotransporters IIa and IIc. However, the interaction between these hormones on phosphate excretion is not clearly understood. We performed the present study to evaluate whether the existence of sufficient parathyroid hormone is necessary for full phosphaturic function of FGF-23 or not.

Methods

In this case-control study, 19 patients with hypoparathyroidism and their age- and gender-matched normal population were enrolled. Serum calcium, phosphate, alkaline phosphatase,parathyroid hormone, FGF-23, 25(OH)D, 1,25(OH)2D and Fractional excretion of phosphorous were assessed and compared between the two groups, using SPSS software.

Results

The mean serum calcium and parathyroid hormone level was significantly lower in hypoparathyroid patients in comparison with the control group (P < 0.001 and P < 0.001, respectively). We found high serum level of phosphate and FGF-23 in hypoparathyroid patients compared to the control group (P < 0.001 and P < 0.001, respectively). However, there was no significant difference in Fractional excretion of phosphorous or 1,25OH2D level between the two groups. There was a positive correlation between serum FGF-23 and Fractional excretion of phosphorous just in the normal individuals (P < 0.001, r = 0.79).

Conclusions

Although the FGF-23 is a main regulator of urinary phosphate excretion but the existence of sufficient parathyroid hormone is necessary for the full phosphaturic effect of FGF-23.
Kidney-targeted baicalin-lysozyme conjugate ameliorates renal fibrosis in rats with diabetic nephropathy induced by streptozotocin
Authors: Zheng Xiao-peng , Nie Qing , Feng Jing , Fan Xiao-yan , Jin Yue-lei , Chen Guang , Du Ji-wei
Published: May 2020

Background

Diabetic nephropathy (DN) is one of the most common and serious complications of diabetes, and is the most important cause of death for diabetic patients. Baicalin (BAI) has anti-oxidative, anti-inflammatory and anti-apoptotic activities, which play a role in attenuating insulin resistance and protecting the kidney. Moreover, cell-specific targeting of renal tubular cells is an approach to enhance drug accumulation in the kidney.

Methods

Forty-five Sprague-Dawley rats were divided into four groups. A diabetes model was created using streptozotocin (STZ) intraperitoneally injection. The four groups included: Control group (n = 10), DN (n = 15), BAI treatment (BAI;n = 10) and BAI-LZM treatment (BAI-LZM;n = 10) groups. In the current study, the renoprotection and anti-fibrotic effects of BAI-lysozyme (LZM) conjugate were further investigated in rats with DN induced by STZ compared with BAI treatment alone.

Results

The results suggest that BAI-LZM better ameliorates renal impairment, metabolic disorder and renal fibrosis than BAI alone in rats with DN, and the potential regulatory mechanism likely involves inhibiting inflammation via the nuclear factor-κB signaling pathway, inhibiting extracellular matrix accumulation via the transforming growth factor-β/Smad3 pathway and regulating cell proliferation via the insulin-like growth factor (IGF)-1/IGF-1 receptor/p38 Mitogen-activated protein kinase (MAPK) pathway. BAI and the kidney-targeted BAI-LZM can utilize the body’s cytoprotective pathways to reactivate autophagy (as indicated by the autophagy markers mechanistic target of rapamycin and sirtuin 1 to ameliorate DN outcomes.

Conclusions

Our data support the traditional use ofS. baicalensisas an important anti-DN traditional chinese medicine (TCM), and BAI, above all BAI-LZM, is a promising source for the identification of molecules with anti-DN effects.
Heavy chain deposition disease presenting with raised anti-GBM antibody levels; a case report
Authors: Turner Michael , Crawford Anna , Winterbottom Claire , Flossmann Oliver , Alchi Bassam , Soares Maria , Bhandary Umanath
Published: May 2020

Background

Monoclonal immunoglobulin deposition disease (MIDD) is a rare condition accounting for < 1% of histopathological diagnoses made on kidney biopsy1. The best outcomes are seen in those diagnosed and treated promptly, but delay to diagnosis is common with the largest series reporting a median time from onset of renal impairment to diagnosis of 12 months2. Here, we report a case of the heavy chain subset of MIDD presenting with positive anti-glomerular basement membrane (anti-GBM) antibodies obscuring the true diagnosis.

Case presentation

Here, we present a challenging case presenting with oedema, haematoproteiuria, and new renal impairment. Anti-GBM antibodies were positive and prompted treatment as atypical anti-GBM disease. However, they were ultimately proven to be monoclonal and secondary to myeloma. The final diagnosis facilitated effective myeloma treatment which led to complete remission and independence from renal replacement therapy.

Conclusions

This case reinforces the importance of comprehensive histopathological and haematological assessment in making the correct diagnosis. Here it facilitated effective treatment and recovery of renal function.
Longitudinal changes of self-perceived manual ability the first year after stroke: a cohort study
Authors: Ekstrand Elisabeth , Sunnerhagen Katharina S. , Persson Hanna C. , Lundgren-Nilsson Åsa , Alt Murphy Margit
Published: May 2020

Background

Recovery patterns of motor function and activity capacity of the upper extremity after stroke have been described, but less is known about longitudinal changes of perceived manual activity performance. The aim of this study was to investigate longitudinal changes of self-perceived manual ability at several timepoints from onset until 12 months post-stroke in a cohort of consecutively recruited individuals with mild, moderate and severe stroke.

Methods

The study included 106 participants from a non-selected cohort with first-ever mild, moderate or severe stroke and impaired upper extremity function (Stroke Arm Longitudinal Study at the University of Gothenburg, SALGOT). Self-perceived manual ability was assessed with the ABILHAND Questionnaire at 3 and 10 days, 4 weeks, 3, 6 and 12 months after stroke. Longitudinal change was assessed by linear mixed models (fixed and random effects) and adjusted models were built by adding effects of cofactors age, gender, stroke severity, living condition and affected hand.

Results

Self-perceived manual ability increased over time the first year after stroke for the total group and the subgroups. The final adjusted model for the total group included fix-effects of time (expected mean change 0.24 logits per month) adjusted by age (− 0.06 per year) and stroke severity (− 0.19 per NIHSS-score). In addition to significant effect of time, the adjusted models for moderate stroke subgroup included fixed effect of age, and for mild and severe subgroups there was an interaction effect between time and age. Further analyses between time-points showed that no significant change of self-perceived manual ability was detected beyond 3 months post-stroke.

Conclusions

Self-perceived manual ability increased over time the first year after stroke, and this change was to some degree modulated by age and stroke severity at onset. Most of the improvements occurred early, predominantly within the first three months after stroke.

Background

Diverse mechanisms including infections, autoimmune inflammatory reactions, neoplasms, and degeneration are involved in the central nervous system in cases of acquired immune deficiency syndrome. In such cases, it is difficult to determine the precise pathogenesis by radiological examination and laboratory testing.

Case presentation

We report a 37-year-old Japanese woman who had untreated hypertension and gender identity disorder and had been taking testosterone injections since she was 19 years old. She developed a headache and visual field deficits together with elevated blood pressure. According to radiological findings, she was initially suspected as having posterior reversible encephalopathy syndrome in the right parieto-occipital lobe with reversible cerebral vasoconstriction syndrome. Human immunodeficiency virus antibody was positive and the CD4+ T-lymphocyte count was 140 cells/μl. Therefore, antiretroviral therapy was started. Antiretroviral therapy suppressed the activity of acquired immune deficiency syndrome but worsened her visual symptoms and expanding radiological lesions. Brain biopsy led to the diagnosis of CD8+ encephalitis, and she also fulfilled the diagnosis of paradoxical immune reconstitution inflammatory syndrome. Corticosteroid therapy alleviated her symptoms.

Conclusions

This is a rare case of CD8+ encephalitis, with an exacerbation owing to paradoxical immune reconstitution inflammatory syndrome after antiretroviral therapy, which radiologically mimicked posterior reversible encephalopathy syndrome. Corticosteroid therapy was effective; thus, it is important to provide a pathological diagnosis in such cases.
Fabry disease presenting as bilateral medial medullary infarction with a “heart appearance” sign: a case report
Authors: Jiang Shuai , Wang Lei , Yan Yuying , Zhu Qiange , Wan Jincheng , Sun Jiayu , Wu Bo
Published: May 2020

Background

The etiologic determinants of cryptogenic stroke remain a diagnostic challenge in clinical practice. Fabry disease (FD) is one of the monogenic causes of stroke that may remain unrecognized as a potential contributing causative factor, because of its rarity and difficulty in diagnosis. We report a case with rare bilateral medial medullary infarction manifesting as “heart appearance” who was diagnosed with FD.

Case presentation

A 51-year-old Chinese man presented with acute dysarthria and mild tetraparesis. In the 24 h following admission, the patient rapidly developed progressive flaccid quadriplegia and tongue weakness, necessitating ventilator support. Immediate magnetic resonance imaging of the brain showed heart-shaped appearance of bilateral medial medullary infarction. The patient suffered two new subcortical infarcts 40 days after the first. Detailed Family history and physical examination indicated symptoms consistent with FD, which was confirmed by very low alpha galactosidase A levels and a missense mutation of the alpha-galactosidase A gene.

Conclusions

We report what appears to be the first case of FD manifesting as bilateral medial medullary infarction. Our case suggests that clinicians should consider the possibility of FD in patients with cryptogenic stroke, especially when combined with infarction in the vertebrobasilar artery system, renal insufficiency, or cardiomyopathy. A detailed analysis of subtle historical clues and performing a complete physical examination on stroke patients would help promote earlier diagnosis of FD.
Repeated successful vaginal delivery in a pregnant woman with unrepaired ectopia vesicae and split pelvis: a case study
Authors: Liu Shaohua , Qu Xinhua , Song Linlin , Li Ning , Xu Aiqun
Published: May 2020

Ectopia vesicae, or bladder exstrophy, is a rare malformation, more frequently found in males. Very few cases of pregnancy with unrepaired ectopia vesicae have been reported in literature. The majority of these pregnant women with ectopia vesicae have terminated their pregnancies by cesarean section due to malpresentation, preterm labor or other indications. Clemetson concluded that cesarean section was the preferable method of term delivery to avoid postpartum prolapse. We have a different opinion on this because we had an interesting case. A woman with unrepaired ectopia vesicae had two successful vaginal deliveries, in 2009 and 2019 respectively. She recovered well and did not have any symptoms or signs of pelvic organ prolapse (POP) so far.

Case presentation

Let us present this woman with ectopia vesicae who had four pregnancies; two spontaneous abortions and two vaginal deliveries. In 2009, she had a successful vaginal delivery at Yantai Harbor Hospital where the first author worked at that time. She met the first author again surprisingly, during her third trimester in 2019. She had a spacious pelvis and pendulous abdomen. In this fourth pregnancy, the fetus changed its presentation frequently. Still, she had the second vaginal delivery successfully. She recovered fully after delivery and did not have any symptoms or signs of POP. As far as we know, this is the first case that a patient with ectopia vesicae who has been observed for such a long time after multiple vaginal deliveries.

Conclusions

Doctors must evaluate the risk of vaginal delivery or cesarean section and consider maternal-neonatal health. Prior to this, women with repaired or unrepaired ectopia vesicae usually delivered their babies by cesarean section. Our practice shows that vaginal delivery is also a safe and feasible choice for some of these patients, especially for those with unrepaired, mild types of ectopia vesicae who experience no other dangerous or uncomfortable symptoms.
Perioperative imaging in patients treated with resection of brain metastases: a survey by the European Association of Neuro-Oncology (EANO) Youngsters committee

Published: May 2020

Background

Neurosurgical resection represents an important treatment option in the modern, multimodal therapy approach of brain metastases (BM). Guidelines for perioperative imaging exist for primary brain tumors to guide postsurgical treatment. Optimal perioperative imaging of BM patients is so far a matter of debate as no structured guidelines exist.

Methods

A comprehensive questionnaire about perioperative imaging was designed by the European Association of Neuro-Oncology (EANO) Youngsters Committee. The survey was distributed to physicians via the EANO network to perform a descriptive overview on the current habits and their variability on perioperative imaging. Chi square test was used for dichotomous variables.

Results

One hundred twenty physicians worldwide responded to the survey. MRI was the preferred preoperative imaging method (93.3%). Overall 106/120 (88.3%) physicians performed postsurgical imaging routinely including MRI alone (62/120 [51.7%]), postoperative CT (29/120 [24.2%]) and MRI + CT (15/120 [12.5%]). No correlation of postsurgical MRI utilization in academic vs. non-academic hospitals (58/89 [65.2%] vs. 19/31 [61.3%], p = 0.698) was found. Early postoperative MRI within ≤72 h after resection is obtained by 60.8% of the participants. The most frequent reason for postsurgical imaging was to evaluate the extent of tumor resection (73/120 [60.8%]). In case of residual tumor, 32/120 (26.7%) participants indicated to adjust radiotherapy, 34/120 (28.3%) to consider re-surgery to achieve complete resection and 8/120 (6.7%) to evaluate both.

Conclusions

MRI was the preferred imaging method in the preoperative setting. In the postoperative course, imaging modalities and timing showed high variability. International guidelines for perioperative imaging with special focus on postoperative MRI to assess residual tumor are warranted to optimize standardized management and adjuvant treatment decisions for BM patients.
A phase II JN-I-10 efficacy study of IDRF-based surgical decisions and stepwise treatment intensification for patients with intermediate-risk neuroblastoma: a study protocol

Published: May 2020

Background

Few clinical trials have been reported for patients with intermediate-risk neuroblastoma because of the scarcity of the disease and the variety of clinical and biological characteristics. A multidisciplinary treatment that consists of multidrug chemotherapy and surgery is expected to lead to a good prognosis with few complications. Therefore, a clinical trial for patients with intermediate-risk tumors was designed to establish a standard treatment that reduces complications and achieves good outcomes.

Methods

We planned a prospective phase 2, single-arm study of the efficacy of image-defined risk factors (IDRF)-based surgical decision and stepwise treatment intensification for patients with intermediate-risk neuroblastomas. For the localized tumor group, IDRF evaluations will be performed after each three-course chemotherapy, and surgery will be performed when appropriate. For patients with metastatic tumors, a total of five chemotherapy courses will be performed, and primary lesions will be removed when the IDRF becomes negative. The primary endpoint is 3-year progression-free survival rate, and the secondary endpoints include 3-year progression-free survival rates and overall survival rates of the localized group and the metastasis group and the incidence of adverse events. From international results, 75% is considered an appropriate 3-year progression-free survival rate. If this trial’s expected 3-year progression-free survival rate of 85% is statistically greater than 75% in the lower limit of the 95.3% confidence interval, with an accuracy 10% (85 ± 10%), both groups require more than 65 patients.

Discussion

This study is the first clinical trial on the efficacy of IDRF-based surgical decision and stepwise treatment intensification for patients with intermediate-risk neuroblastomas. We expect that this study will contribute to the establishment of a standard treatment for patients with intermediate-risk neuroblastoma.

Symptomatic remission affects employment outcomes in schizophrenia patients
Authors: Wang San-Ping , Wang Jung-Der , Chang Jer-Hao , Wu Bo-Jian , Wang Tso-Jen , Sun Hsiao-Ju
Published: May 2020

Background

Remission criteria were proposed by Andreasen et al. for classifying patients with schizophrenia according to the severity of psychopathology. Up to the present time, there have been no cohort studies exploring the association between remission status and employment outcomes in patients with schizophrenia. The study explored whether symptomatic remission is significantly associated with employment outcomes in a two-year longitudinal study.

Methods

All 525 stable patients with schizophrenia in the therapeutic community of a public mental hospital in Taiwan were recruited between 2013 and 2015. Employment outcomes, defined as the cumulative on-the-job duration (months/per year) and income (new Taiwan dollars, NT$/per year), were investigated at the end of 1- and 2-year follow-up periods after enrollment. For repeated measurements, linear mixed models were constructed to examine the association between symptomatic remission and employment outcomes after controlling for potential confounding variables including age, sex, education, type and daily dose of antipsychotics, cognitive function, psychosocial functioning and initial employment type.

Results

The average age of patients was 51.8 years, and 65.3% were males. Among them, 124 patients (23.6%, 124/525) met the remission criteria at baseline. The linear mixed-model analysis showed that patients who had symptomatic remission were employed 0.8 of a month longer (p = 0.029) and earned NT$3250 more (p = 0.001) within 1 year than those who did not show symptomatic remission.

Conclusion

Our study suggests that assessing symptomatic remission is a useful part of monitoring treatment effectiveness for schizophrenia, and all strategies targeting the bio-psycho-social domains to attain symptomatic remission are paramount to maintaining favorable employment outcomes.
A cross-sectional study on spouse and parent differences in caregiving experiences of people living with schizophrenia in rural China
Authors: Yu Yu , Li Tong-xin , Li Yi-lu , Qiu Dan , Xi Shi-jun , Xiao Shui-yuan , Tebes Jacob Kraemer
Published: May 2020

Background

Conflicting evidence exists on whether parent or spouse caregivers experience better outcomes when caring for family members with schizophrenia. The current study aims to examine relative caregiving experiences and impacts of spouse and parent caregivers for people living with schizophrenia (PLS) in China.

Methods

A cross-sectional study was conducted in a sample of 264 community-dwelling primary family caregivers of PLS. Face-to-face interviews were conducted to collect information on family caregiving activities; negative caregiving impacts including objective and subjective burden, and caregiver psychological distress such as depression and anxiety; positive caregiving impacts including caregiving rewarding feelings, and family functioning for spouse and parent caregivers.

Results

Both types of caregivers report engaging in similar caregiving activities and report comparable levels of objective burden. However, parent caregivers report significantly higher subjective burden than spouse caregivers (b = 7.94, 95%CI:2.08, 13.80, P < 0.01), which is also reflected in significantly higher depression (b = 3.88, 95%CI:1.35, 6.41, P < 0.01) and anxiety (b = 2.53, 95%CI: 0.22, 4.84, P < 0.05), and lower family functioning (b = − 1.71, 95%CI: − 2.73, − 0.49, P < 0.01). Despite these differences, both groups of caregivers report comparable rewarding feelings about caregiving.

Conclusions

Our findings have implications for family caregivers globally, but especially for countries that adhere to Confucian cultural values and provide guidance for future family intervention programs. Such programs may do well to incorporate cultural values and beliefs in understanding caregiving and kinship family dynamics so as to support family caregivers, and in particular, the specific vulnerabilities of parent caregivers.
Perinatal mental distress in a rural Ethiopian community: a critical examination of psychiatric labels
Authors: Molenaar Jil , Hanlon Charlotte , Alem Atalay , Wondimagegn Dawit , Medhin Girmay , Prince Martin , Stevenson Edward G. J.
Published: May 2020

Background

Perinatal mental distress poses a heavy burden in low- and middle-income countries (LMICs). This study investigated perceptions and experiences of perinatal mental distress among women in a rural Ethiopian community, in an effort to advance understanding of cross-cultural experiences of perinatal mental distress.

Methods

We employed a sequential explanatory study design. From a population-based cohort study of 1065 perinatal women in the Butajira Health and Demographic Surveillance Site, we purposively selected 22 women according to their scores on a culturally validated assessment of perinatal mental distress (the Self-Reporting Questionnaire). We examined concordance and discordance between qualitative semi-structured interview data (‘emic’ perspective) and the layperson-administered fully-structured questionnaire data (‘etic’ perspective) of perinatal mental distress. We analysed the questionnaire data using summary statistics and we carried out a thematic analysis of the qualitative data.

Results

Most women in this setting recognised the existence of perinatal mental distress states, but did not typically label such distress as a discrete illness. Instead, perinatal mental distress states were mostly seen as non-pathological reactions to difficult circumstances. The dominant explanatory model of perinatal mental distress was as a response to poverty, associated with inadequate food, isolation, and hopelessness. Support from family and friends, both emotional and instrumental support, was regarded as vital in protecting against mental distress. Although some women considered their distress amenable to biomedical solution, many thought medical help-seeking was inappropriate. Integration of perspectives from the questionnaire and semi-structured interviews highlighted the important role of somatic symptoms and nutritional status. It also demonstrated the differential likelihood of endorsement of symptoms when screening tools versus in-depth interviews are used.

Conclusions

This study highlights the importance of the wider social context within which mental health problems are situated, specificially the inseparability of mental health from gender disadvantage, physical health and poverty. This implies that public health prevention strategies, assessments and interventions for perinatal distress should be developed from the bottom-up, taking account of local contexts and explanatory frameworks.
Expressions of masculinity and associations with suicidal ideation among young males
Authors: King Tania L. , Shields Marissa , Sojo Victor , Daraganova Galina , Currier Dianne , O’Neil Adrienne , King Kylie , Milner Allison
Published: May 2020

Background

Adolescent boys and young men are at particular risk of suicide. Suicidal ideation is an important risk factor for suicide, but is poorly understood among adolescent males. Some masculine behaviors have been associated with deleterious effects on health, yet there has been little quantitative examination of associations between masculinity and suicide or suicidal ideation, particularly among boys/young men. This study aimed to examine associations between conformity to masculine norms and suicidal ideation in a sample of adolescents.

Methods

A prospective cohort design, this study drew on a sample of 829 Australian boys/young men from the Australian Longitudinal Study on Male Health. Boys were 15–18 years at baseline, and 17–20 years at follow-up. Masculine norms (Wave 1), were measured using the Conformity to Masculine Norms Inventory (CMNI-22). Suicidal ideation (Wave 2) was a single-item from the Youth Risk Behavior Survey. Logistic regression analysis was conducted, adjusting for available confounders including parental education, Indigenous Australian identity and area disadvantage.

Results

In adjusted models, greater conformity to violent norms (OR = 1.23, 95% Confidence Interval [CI]: 1.03–1.47) and self-reliance norms (OR = 1.40, 95% CI: 1.15–1.70) was associated with higher odds of reporting suicidal ideation. Greater conformity to norms regarding heterosexuality was associated with reduced odds of reporting suicidal ideation (OR = 0.80, 95% CI: 0.68–0.91).

Conclusions

These results suggest that conforming to some masculine norms may be deleterious to the mental health of young males, placing them at greater risk of suicidal ideation. The results highlight the importance of presenting young males with alternative and multiple ways of being a male. Facilitating a relaxation of norms regarding self-reliance, and encouraging help-seeking, is vital. Furthermore, dismantling norms that rigidly enforce masculine norms, particularly in relation to heteronormativity, is likely to benefit the broad population of males, not only those who do not conform to heterosexual and other masculine norms.
Soil-transmitted helminthiasis in four districts in Bangladesh: household cluster surveys of prevalence and intervention status

Published: May 2020

Background

In 2016, after 8 years of twice-annual nationwide preventive chemotherapy (PC) administration to school-age children (SAC), the Bangladesh Ministry of Health & Family Welfare (MOHFW) sought improved impact and intervention monitoring data to assess progress toward the newly adopted goal of eliminating soil-transmitted helminthiasis (STH) as a public health problem.

Methods

We surveyed four Bangladeshi districts between August and October 2017. We conducted a multi-stage, cluster-sample, household survey which produced equal-probability samples for preschool-age children (PSAC; 1–4 years), SAC (5–14 years), and adults (≥ 15 years). Standardized questionnaires were administered, using Android-based smart phones running an Open Data Kit application. Stool samples were collected and testing for STH prevalence and infection intensity used the Kato-Katz technique.

Results

In all, 4318 stool samples were collected from 7164 participants. Estimates of STH prevalence by risk group in three of the four surveyed districts ranged from 3.4 to 5.0%, all with upper, 1-sided 95% confidence limits < 10%. However, STH prevalence estimates in Sirajganj District ranged from 23.4 to 29.1%. Infections in that district were spatially focal; four of the 30 survey clusters had > 50% prevalence in at least one risk group. Among all tested specimens, Ascaris lumbricoides was the most common STH parasite [8.2% (n = 352)], followed by Trichuris trichiura [0.9% (n = 37)], and hookworm [0.6% (n = 27)]. In each district, PC coverage among SAC was above the 75% program target but did not exceed 45% among PSAC in any district. Improved sanitation at home, school, or work was over 90% in all districts.

Conclusions

In the three low-prevalence districts, the MOHFW is considering decreasing the frequency of mass drug administration, per World Health Organization (WHO) guidelines. Also, the MOHFW will focus programmatic resources and supervisory efforts on Sirajganj District. Despite considering WHO guidance, the MOHFW will not expand PC administration to women of reproductive age partly due to the low prevalence of hookworm and T. trichiura, the STH parasites that contribute most to morbidity in that risk group. Data collected from surveys such as ours would help effectively guide future STH control efforts in Bangladesh and elsewhere.
Assessment of malaria as a public health problem in and around Arjo Didhessa sugar cane plantation area, Western Ethiopia
Authors: Dufera Mebrate , Dabsu Regea , Tiruneh Gemechu
Published: May 2020

Background

Although much progress has been made in reducing malaria morbidity and mortality worldwide in the last decade, nationally malaria remains the third leading cause of death and still considered a major public health problem. Therefore, this study was aimed to assess malaria as a public health problem in and around the sugar cane plantation area of Arjo Didhessa sugar factory, Western Ethiopia.

Methods

A community-based cross-sectional study supplemented with clinical retrospective data, which included 452 study subjects was recruited and the study period was extended from May 2016 up to November of 2017. A standardized questionnaire was used to assess malaria risk factors and blood samples were received from all study participants and further subjected to Giemsa staining for determination of malaria prevalence. Data were analyzed by SPSS version 20. Malaria risk factors were identified by multivariate logistic regression at a significance level of P < 0.05.

Results

The overall malaria prevalence was 3.1%; Plasmodium vivax is the main type of malaria parasite. Overnight outdoor sleeping and improper utilization of mosquito bed nets were found to be statistically significant as malaria risk factors in the community. In the retrospective studies of five years, the peak malaria cases (13.84%) were reported in 2013 and the lowest cases (1.24%) in 2017.

Conclusions

The figure for malaria witnessed in this area remains higher than the observed national malaria prevalence indicating malaria remains a public health problem. Therefore, we suggest the factory administrators and health care professionals work more on raising awareness to avoid night outdoor sleeping and promote frequent and appropriate utilization of insecticide-treated nets in line with regular indoor residual spraying.
Modern contraceptive use and factors associated with use among postpartum women in Ethiopia; further analysis of the 2016 Ethiopia demographic and health survey data
Authors: Dagnew Gizachew Worku , Asresie Melash Belachew , Fekadu Gedefaw Abeje , Gelaw Yared Mulu
Published: May 2020

Background

The postpartum period is a critical time to improve maternal and child health. It is a time for accessing contraceptives to prevent short inter-pregnancy intervals. More than 95% of postpartum women do not want to get pregnant within 12 months. However, many women in Ethiopia experience an unintended pregnancy, and there is low information about postpartum contraceptive use among women who have family planning demand. Therefore, this study aimed to estimate the prevalence of postpartum contraceptive use and its predictors among women who give birth 12 months before the survey in Ethiopia.

Methods

We used the 2016 Ethiopia demographic health survey data for this analysis. The survey was a community-based cross-sectional study conducted from January 18 to June 27, 2016. The survey employed a two-stage stratified cluster sampling technique. A total of 2304 postpartum women were included. Bivariate and multivariable logistics regressions were done to identify factors associated with postpartum contraceptive use. A p-value < 0.05 was used to declare statistical significance.

Results

About 23.7% (23.7, 95% CI: 20.7–27.0%) of postpartum women were using modern contraceptives. Women who were urban residents (AOR = 2.18; 95%CI: 1.34–3.55), those who attended secondary or higher education (AOR = 1.79; 95%CI: 1.04–3.10), women who attended 1–3 (AOR = 2.33; 95%CI:1.27–4.25) or 4 or more ANC visits (AOR = 2.59; 95%CI:1.43–4.69) and women who delivered at a health facility (AOR = 1.86; 95%CI: 1.23–2.81) had higher odds of modern contraceptive use during the postpartum period. Similarly, women who reported the last child was no more wanted (AOR = 1.83; 95%CI: 1.01–3.31), women who decided for contraceptive use (AOR = 2.03; 95%CI: 1.13–3.65) and women whose recent child was male (AOR = 1.38; 95%CI: 1.01–1.88) had higher odds of modern contraceptive use.

Conclusion

Postpartum contraceptive use was low in Ethiopia. Strengthening health facility delivery, promoting girls’ education and encouraging women’s participation in deciding for contraceptive use would improve the uptake of modern contraceptives use during the postpartum period.
Improving dietary intake during lunch through the provision of a healthy school lunch at Dutch primary schools: design of a pretest-posttest effectiveness study

Published: May 2020

Background

Since there is a shift from eating lunch at home to eating lunch at primary schools in the Netherlands, providing a school lunch may be an important opportunity to improve the diet quality of Dutch children. Therefore, the aim of this Healthy School Lunch project is to encourage healthy eating behavior of children at primary schools by offering a healthy school lunch, based on the guidelines for a healthy diet. In this study, two research questions will be addressed. The first research question is: What and how much do children consume from a self-served school lunch and how do they evaluate the lunch? The second research question is: Do children compensate healthier school lunches by eating less healthy outside school hours? The purpose of this paper is to report the rationale and study design of this study.

Methods

In the Healthy School Lunch project children in grades 5–8 (aged 8–12 years) of three primary schools in the Netherlands will receive a healthy school lunch for a 6-month period. To answer research question 1, lunch consumption data will be collected at baseline and again at 3- and 6-months. This will be measured with lunch photos and questionnaires among children. To answer the second research question, a quasi-experimental, pre-test post-test intervention-comparison group design (3 intervention schools and 3 comparison schools) will be carried out. Potential compensation effects will be measured with a single brief questionnaire among parents at the three intervention and three comparison schools at month 6 of the lunch period. The school lunch will also be evaluated by parents (discussion groups) and teachers and support staff (brief questionnaires).

Discussion

Results of this study will provide valuable information to influence future school lunch interventions and policies.

Background

The screen-media landscape has changed drastically during the last decade with wide-scale ownership and use of new portable touchscreen-based devices plausibly causing changes in the volume of screen media use and the way children and young people entertain themselves and communicate with friends and family members. This rapid development is not sufficiently mirrored in available tools for measuring children’s screen media use. The aim of this study was to develop and evaluate a parent-reported standardized questionnaire to assess 6–10-year old children’s multiple screen media use and habits, their screen media environment, and its plausible proximal correlates based on a suggested socio-ecological model.

Methods

An iterative process was conducted developing the SCREENS questionnaire. Informed by the literature, media experts and end-users, a conceptual framework was made to guide the development of the questionnaire. Parents and media experts evaluated face and content validity. Pilot and field testing in the target group was conducted to assess test-retest reliability using Kappa statistics and intraclass correlation coefficients (ICC). Construct validity of relevant items was assessed using pairwise non-parametric correlations (Spearman’s). The SCREENS questionnaire is based on a multidimensional and formative model.

Results

The SCREENS questionnaire covers six domains validated to be important factors of screen media use in children and comprises 19 questions and 92 items. Test-retest reliability (n = 37 parents) for continuous variables was moderate to substantial with ICC’s ranging from 0.67 to 0.90. For relevant nominal and ordinal data, kappa values were all above 0.50 with more than 80% of the values above 0.61 indicating good test-retest reliability. Internal consistency between two different time use variables (fromn = 243) showed good correlations with rho ranging from 0.59 to 0.66. Response-time was within 15 min for all participants.

Conclusions

SCREENS-Q is a comprehensive tool to assess children’s screen media habits, the screen media environment and possible related correlates. It is a feasible questionnaire with multiple validated constructs and moderate to substantial test-retest reliability of all evaluated items. The SCREENS-Q is a promising tool to investigate children screen media use.

Published: May 2020

Background

Accessibility of sexual and reproductive health (SRH) services in many lower-and-middle-income countries (LMICs) and humanitarian settings remains limited, particularly for young people. Young people facing humanitarian crises are also at higher risk for mental health problems, which can further exacerbate poor SRH outcomes. This review aimed to explore, describe and evaluate SRH interventions for young people in LMIC and humanitarian settings to better understand both SRH and psychosocial components of interventions that demonstrate effectiveness for improving SRH outcomes.

Methods

We conducted a systematic review of studies examining interventions to improve SRH in young people in LMIC and humanitarian settings following Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) standards for systematic reviews. Peer-reviewed journals and grey literature from January 1, 2000 to December 31, 2018 were included. Two authors performed title, abstract and full-text screening independently. Data was extracted and analyzed using a narrative synthesis approach and the practice-wise clinical coding system.

Results

The search yielded 813 results, of which 55 met inclusion criteria for full-text screening and thematic analysis. Primary SRH outcomes of effective interventions included: contraception and condom use skills, HIV/STI prevention/education, SRH knowledge/education, gender-based violence education and sexual self-efficacy. Common psychosocial intervention components included: assertiveness training, communication skills, and problem-solving.

Conclusions

Findings suggest that several evidence-based SRH interventions may be effective for young people in humanitarian and LMIC settings. Studies that use double blind designs, include fidelity monitoring, and focus on implementation and sustainability are needed to further contribute to this evidence-base.

Background

An infection with high-risk human papillomavirus (HPV) is the obligatory aetiological factor for the development of cervical cancer. In Switzerland, the prevention strategy for cervical cancer is based on primary prevention via HPV vaccination and secondary prevention with an opportunistic screening programme for precancerous lesions. Vaccination is recommended to 11–26 years old male and female persons. The objective of the study was to assess the epidemiological impact on cervical cancer of switching from the currently implemented programme with the 4-valent vaccine to the 9-valent vaccine, in an 11–26 years old gender-neutral vaccination programme in Switzerland.

Methods

A previously validated dynamic transmission model of HPV infections was adapted and calibrated to the Swiss setting assuming an 80% coverage rate in HPV-vaccination and lifelong vaccine type-specific protection. A gender-neutral vaccination programme (males and females) for 11–26 years old with a 9-valent HPV vaccine was compared with the current 11–26 years old gender-neutral 4-valent vaccination programme. Sensitivity analyses were conducted in order to test the impact of lower vaccination coverage rates and a shorter duration of protection on the model outcomes.

Results

In Switzerland, a 9-valent gender-neutral vaccination programme would result in an additional prevention of 2979 cervical cancer cases, 13,862 CIN3 and 15,000 CIN2 cases, compared with the 4-valent gender-neutral vaccination programme over 100 years. These additional disease cases avoided would correspond to a 24, 36 and 48% cumulative incidence decrease in cervical cancer, CIN3 and CIN2 cases, respectively. It would also prevent additional 741 cervical cancer-related deaths over 100 years. A substantial additional reduction in cervical cancer and precancerous lesions burden is still observed when varying the vaccination coverage rate from 30 to 60% or reducing the duration of protection from lifelong to 20 years.

Conclusions

The switch to the 9-valent vaccine in Switzerland to prevent cervical diseases showed an important contribution in terms of public health impact compared with the 4-valent vaccine in an 11–26 years old gender-neutral population, even with very conservative assumptions such as low coverage rates or low duration of protection and limiting analysis to only cervical disease.

Background

Most contemporary studies suggested that intersegmental parameters including disc height and local lordosis contribute to the sagittal balance of fused lumbar. Although similar clinical outcomes following MIS- and Open-TLIF were reported essentially at the early postoperative time, the comparison of local balance variables after these two different techniques was lack. The radiological differences maybe not relevant to the postoperative efficacy at an earlier post-operation stage. But during the long-term follow-up, the complications with regards to the sagittal imbalance might occur due to the distinct biomechanical properties of fusion level after MIS- and Open-TLIF.

Methods

The patients who underwent a single-level MIS- and Open-TLIF were reviewed retrospectively. The anterior disc height (ADH), posterior disc height (PDH), and segmental lordosis (SL) of the fusion segment were measured using recognition technical fluoroscopy. The mean disc height (MDH) was calculated by (ADH + PDH)/2. The relative DH was normalized by the anterior height of the upper vertebrae. The body mass index (BMI), the pain score of low back and leg visual analogue scale (VAS), Oswestry disability index (ODI), estimated blood loss, and hospital stay length was collected.

Results

A total of 88 patients undergoing a single-level TLIF (MIS and Open) were included. The pre- and post-operative ADH, PDH, MDH, and SL of MIS-TLIF group were 1.57 ± 0.33 cm, 0.79 ± 0.20 cm, 1.18 ± 0.21 cm, 7.36 ± 3.07 and 1.63 ± 0.30 cm, 1.02 ± 0.28 cm, 1.32 ± 0.24 cm, 10.24 ± 4.79 respectively. Whereas, the pre- and post-operative ADH, PDH, MDH, and SL of Open-TLIF group were 1.61 ± 0.40 cm, 0.77 ± 0.21 cm, 1.19 ± 0.24 cm, 9.05 ± 5.48 and 1.81 ± 0.33 cm, 0.98 ± 0.24 cm, 1.39 ± 0.24 cm, 12.34 ± 4,74 respectively. MIS- and Open-TLIF group showed no significant differences in low back VAS, leg VAS, and ODI both in pre-operation and post-operation (P > 0.05). The estimated blood loss and hospital stay length in the MIS-TLIF group were significantly lower than those in the Open-TLIF group (P < 0.05).

Conclusion

MIS- and Open-TLIF provided similar clinical outcomes as the respect of low back VAS, leg VAS, and ODI. MIS-TLIF significantly reduced the blood loss and length of hospital stay though. The intervertebral parameters of DH and SL were both increased significantly, Open-TLIF group presented better sagittal balance in term of ADH and SL variables. The contrast investigation of intersegmental parameters may help the surgeons to figure out the further advantages of MIS-TLIF technique, and then better manage the rehabilitation and prevent the reoperation.
