Contribution of Food from Market Purchases and Home Production to Child Nutrient Intake: Evidence from the EFFECTS Study Baseline Data.

BACKGROUND: Child undernutrition is prevalent in Tanzania, and households rely primarily on local markets and home production as food sources. However, little is known about the contribution of food market purchases to nutrient intakes among children consuming complementary foods. OBJECTIVE: To quantify the relationships between diversity of foods purchased and produced by households and adequate child nutrient intake in Mara, Tanzania. METHODS: Cross-sectional baseline dietary and household food source data from the EFFECTS study (ClinicalTrials.gov: NCT03759821) were collected from mothers of 586 children aged 9-23 months clustered in 80 villages in Mara, Tanzania. We conducted mixed effects linear regressions to quantify the association between diversity of foods consumed at home, from market purchases and home production, and nutrient intake adequacy (based on 24-hour food recalls). RESULTS: Children had inadequate diets, with fewer than half of children consuming adequate amounts of vitamin A, vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B9 (folate), calcium, iron, and zinc. Breastfeeding was associated with higher overall mean adequacy (b=0.15-0.19 across models, p<0.001). Diversity of foods purchased was positively associated with intake of vitamin B12 and calcium (both p<0.001); this effect was attenuated among breastfed children. Among non-breastfed children, production diversity was positively associated with vitamin A intake (b=0.04, p<0.05) but not with intake of other nutrients. CONCLUSIONS: Both household food purchase diversity and food production diversity were positively associated with children's nutrient intake in rural Mara, Tanzania. Nutrition programming should consider the role of food markets in addition to home food production to improve child diets.

Management of recurrent giant hemangiopericytoma: illustrative cases.

BACKGROUND: Hemangiopericytoma (HPC) is a rare malignancy accounting for 0.4% of intracranial tumors. HPCs are characterized by local aggressiveness, high rates of recurrence, and a tendency to metastasize to extracranial sites. These features make management of HPCs challenging, often requiring a combination of radical resection and radiation. Given their rarity, optimal treatment algorithms remain undefined. OBSERVATIONS: The authors report a series of four patients who underwent resection of intracranial HPC. Mean age at presentation was 49.3 years. Three patients had reoperation for progression of residual tumor, and one patient was surgically retreated for recurrence. One patient received adjuvant radiotherapy following initial resection, and three patients received adjuvant radiotherapy following resection of recurrent or residual disease. There was one death in the series. Average progression-free survival and overall survival following the index procedure were 32.8 and 82 months, respectively. Progression occurred locally in all patients, with metastatic recurrence in one patient. LESSONS: The current gold-standard treatment for intracranial HPC consists of gross-total resection followed by radiation therapy. This approach allows satisfactory local control; however, given the tendency for these tumors to recur either locally or distally within or outside of the central nervous system, there is a need for salvage therapies to improve long-term outcomes for patients.

Women's empowerment and child anthropometric failures across 28 sub-Saharan African countries: A cross-level interaction by Gender Inequality Index.

Background: Child undernutrition remains a major global health issue, particularly in sub-Saharan Africa (SSA). Given the important role mothers play in early childhood health and development, we examined how individual-level women's empowerment and country-level Gender Inequality Index (GII) are jointly related with child undernutrition in SSA. Methods: We pooled recent Demographic and Health Surveys from 28 SSA countries. For 137,699 children <5 years old, undernutrition was defined using anthropometric failures (stunting, underweight, wasting). Women's empowerment was assessed using three domains of Survey-based Women's EmPowERment (SWPER) index: attitude to violence, social independence, and decision-making; and country-level gender inequality was measured using GII from United Nations Development Programme. Three-level logistic regression was conducted to examine the joint associations of SWPER and GII as well as their interactions with child anthropometric failures, after adjusting for sociodemographic covariates. Results: Overall, 32.85% of children were stunted, 17.63% were underweight, and 6.68% had wasting. Children of mothers with low-level of empowerment for all domains of SWPER had higher odds of stunting (attitude to violence: OR=1.15; 95% CI, 1.11-1.19; social independence: OR=1.21; 95% CI, 1.17-1.25; decision-making: OR=1.16; 95% CI, 1.12-1.20), and consistent results were found for underweight and wasting. Independent of women's empowerment, country-level GII increased the probability of underweight (ranging ORs=1.46; 95% CI, 1.15-1.85 to 1.50; 95% CI, 1.18-1.90) and wasting (ranging ORs=1.56; 95% CI, 1.24-1.97 to 1.61; 95% CI, 1.27-2.03). Significant interaction was found between women's empowerment and country-level GII for stunting and underweight (p<0.05). Conclusions: In SSA countries with greater gender inequality, improving women's social independence and decision-making power in particular can reduce their children's risk of anthropometric failures. Policies and interventions targeted at strengthening women's empowerment should consider the degree of gender inequality in each country.

CT guided biopsy for osteodiscitis reduces cost of hospitalization in the landscape of increasing intravenous drug use: A single center retrospective analysis.

OBJECTIVE: Osteodiscitis has been demonstrated to show significant morbidity and mortality. Cultures and CT guided biopsy (CTB) are commonly used diagnosis of osteodiscitis. This study's purpose is to evaluate the cost burden of CTB and to evaluate how IVDU affects patient management in the setting of osteodiscitis. METHODS: Patients admitted for osteodiscitis from 2011-2021 were retrospectively reviewed and stratified into cohorts by CTB status. Additional cohorts were stratified by Intravenous Drug Use (IVDU). Patient demographics, total cost of hospitalization, length of hospitalization, time to biopsy, IVDU status, and other factors were recorded. T-Test, Chi-squared analysis, and ANOVA were used for statistical analysis. RESULTS: Total cost of hospitalization was recorded for 140 patients without CTB and 346 patients with CTB. Average cost of hospitalization for non-CTB was $227,317.86 compared to CTB at $119,799.20 (p < 0.001). Length of stay (LOS) was found to be 18.01 days for non-CTB and 14.07 days for CTB patients (0.00282). When stratified by days until biopsy, patients who had CTB sooner, had significantly reduced cost of hospitalization (p = 0.0003). Patients with IVDU history were significantly younger (p < 0.001) with lower BMI (p < 0.001) and a significantly different clinical profile. There was a significant difference in positive open biopsy when separated by IVDU status (p = 0.025). CONCLUSION: CTB was associated with significantly reduced cost of hospitalization and LOS compared to non-CTB. IVDU patients with osteodiscitis have significantly different clinical profiles than non-IVDU that may impact diagnosis and treatment. Further work is indicated to elucidate causes of these differences to provide high value care to patients with osteodiscitis.

A meta-analytic review of the implementation characteristics in parenting interventions to promote early child development.

This review summarizes the implementation characteristics of parenting interventions to promote early child development (ECD) outcomes from birth to 3 years. We included 134 articles representing 123 parenting trials (PROSPERO record CRD42022285998). Studies were conducted across high-income (62%) and low-and-middle-income (38%) countries. The most frequently used interventions were Reach Up and Learn, Nurse Family Partnership, and Head Start. Half of the interventions were delivered as home visits. The other half used mixed settings and modalities (27%), clinic visits (12%), and community-based group sessions (11%). Due to the lack of data, we were only able to test the moderating role of a few implementation characteristics in intervention impacts on parenting and cognitive outcomes (by country income level) in the meta-analysis. None of the implementation characteristics moderated intervention impacts on cognitive or parenting outcomes in low- and middle-income or high-income countries. There is a significant need in the field of parenting interventions for ECD to consistently collect and report data on key implementation characteristics. These data are needed to advance our understanding of how parenting interventions are implemented and how implementation factors impact outcomes to help inform the scale-up of effective interventions to improve child development.

Supraorbital Eyebrow Approach for Translamina Terminalis Resection of Third Ventricle Metastasis: 2-Dimensional Operative Video.

Tumors involving the third ventricle are rare, accounting for 0.6%-0.9% of all brain tumors. This deep-seated cavity is surrounded by critical neurovascular structures, making safe surgical resection of lesions in this region challenging. Traditionally, tumors of the third ventricle have been approached through a craniotomy and microsurgical resection.1-4 The supraorbital keyhole approach is a minimally invasive technique that can be used with minimal retraction of the brain and limited craniotomy while establishing a surgical field comparable with what can be achieved using traditional transcranial approaches. In this video, we describe the case of a 54-year-old man who underwent a supraorbital eyebrow approach for translamina terminalis resection of papillary thyroid carcinoma metastasis to the third ventricle. A gross total resection was achieved. The results achieved in our series are comparable with previously published reports of patients who underwent surgical resection of metastatic lesions involving the third ventricle.5-11 The patient consented to the procedure and to the publication of his image.

Fathers' mental health and coping strategies: a qualitative study in Mwanza, Tanzania.

OBJECTIVES: To investigate the nature of paternal mental health problems, their causes and the coping strategies used by fathers of young children under the age of 2 years. DESIGN AND SETTING: We conducted in-depth interviews with fathers, mothers, community leaders and community health workers as well as focus group discussions with fathers-only, mothers-only and mixed groups of fathers and mothers. Respondents provided their perspectives on the psychosocial challenges affecting fathers and how fathers responded to their mental health problems. Data were triangulated across stakeholders and analysed using thematic content analysis. SETTING: The study was conducted in four communities in Mwanza, Tanzania. PARTICIPANTS: The total sample included 56 fathers, 56 mothers and 8 community stakeholders that were equally distributed across the four communities. RESULTS: Respondents highlighted a spectrum of mental health concerns affecting fathers, including elevated parenting stress, depressive symptoms, and anxiety. Causes of paternal mental health problems included poverty, child-related concerns, marital problems and family illness. When asked about paternal coping strategies, both fathers and mothers shared that fathers mostly turned to negative coping strategies to manage their distress, such as paternal alcohol use and poor conflict resolution strategies. However, respondents also shared how some fathers used positive coping strategies, such as seeking out social support from their family and friends, engaging in exercise and leisure activities and relying on their faith. CONCLUSIONS: Overall, this study highlights the importance of supporting positive mental health among fathers. Our findings can inform the design of psychosocial programme components that can be integrated within parenting interventions to promote the well-being of specifically fathers and ultimately improve the family caregiving environment.

Maternal Decision-Making Power and Care-Seeking Behaviors for Acutely Ill Children: A Multilevel Analysis of 33 Sub-Saharan African Countries.

Timely and appropriate healthcare seeking is crucial to reduce child mortality. However, rates of care seeking for acute childhood diseases remain low in sub-Saharan Africa (SSA). This study investigated the association between maternal decision-making power and care-seeking behaviors for children with diarrhea and acute respiratory infection (ARI) in SSA. Demographic and Health Surveys from 33 SSA countries were used in a sample of mother-child pairs (mothers aged 15-49 years; children aged 0-59 months) with a recent child episode of diarrhea (N = 41,729) and ARI (N = 71,966). Maternal decision-making power was defined as making decisions on all four familial topics alone or jointly with the husband/partner. Care-seeking behaviors were measured as seeking care from health providers, other types of providers, and any providers (including both). Multivariable three-level logistic regressions were conducted. Approximately 60% of the sample sought care from any provider (46-48% from health providers versus 13-14% from others). Approximately 28% of mothers had high decision-making power. After adjusting for sociodemographic characteristics, high maternal decision-making power was associated with higher likelihood of seeking care from a health provider for both diarrhea (adjusted odds ratio [aOR] = 1.06, 95% CI = 1.01-1.12) and ARI (aOR = 1.07, 95% CI = 1.03-1.11) and lower likelihood of seeking care from others (aOR = 0.89, 95% CI = 0.82-0.97 for diarrhea; aOR = 0.88, 95% CI = 0.82-0.94 for ARI). Maternal decision-making power was positively associated with their care-seeking behaviors from health providers for acutely ill children in SSA. Women's empowerment interventions that particularly increase women's agency in decision-making may holistically improve health and well-being of the next generation.

Intraoperative ultrasound-assisted endoscopic endonasal transclival marsupialization of an ectopic retrosellar Rathke's cleft cyst: A rare case illustration and systematic review of the literature.

Not every Rathke's cleft cyst (RCC) is confined within the sella between the posterior and anterior lobes of the pituitary gland. Intracranial ectopic RCCs are extremely rare, with only seven cases reported in the literature. In this study, the authors presented a rare case of a symptomatic ectopic retrosellar RCC posterior to the pituitary gland, causing extensive clival erosion. The surgical nuances of the wide marsupialization of the cyst through intraoperative ultrasound-assisted endoscopic endonasal transclival approach are described, and a systematic literature review of intracranial ectopic RCCs is conducted.

Surgical Characteristics of Intracranial Biopsy Using a Frameless Stereotactic Robotic Platform: A Single-Center Experience.

BACKGROUND AND OBJECTIVES: Cranial robotics are a burgeoning field of neurosurgery. To date, all cranial robotic systems described have been computerized, arm-based instruments that take up significant space in the operating room. The Medtronic Stealth Autoguide robot has a smaller operating room footprint and offers multiaxial, frame-based surgical targeting. The authors set out to define the surgical characteristics of a novel robotic platform for brain biopsy in a large patient cohort. METHODS: Patients who underwent stereotactic biopsy using the Stealth Autoguide cranial robotic platform from July 2020 to March 2023 were included in this study. Clinical, surgical, and histological data were collected and analyzed. RESULTS: Ninety-six consecutive patients (50 female, 46 male) were included. The mean age at biopsy was 53.7 ± 18.0 years. The mean target depth was 68.2 ± 15.3 mm. The biopsy diagnostic tissue acquisition rate was 100%. The mean time from incision to biopsy tissue acquisition was 15.4 ± 9.9 minutes. Target lesions were located throughout the brain: in the frontal lobe (n = 32, 33.3%), parietal lobe (n = 21, 21.9%), temporal lobe (n = 22, 22.9%), deep brain nuclei/thalamus (n = 13, 13.5%), cerebellum (n = 7, 7.3%), and brainstem (n = 1, 1.0%). Most cases were gliomas (n = 75, 78.2%). Patients were discharged home on postoperative day 0 or 1 in 62.5% of cases. A total of 7 patients developed postoperative complications (7.2%). CONCLUSION: This cranial robotic platform can be used for efficient, safe, and accurate cranial biopsies that allow for reliable diagnosis of intracranial pathology in a minimally invasive setting.

Chromatinization Modulates Topoisomerase II Processivity.

Type IIA topoisomerases are essential DNA processing enzymes that must robustly and reliably relax DNA torsional stress in vivo. While cellular processes constantly create different degrees of torsional stress, how this stress feeds back to control type IIA topoisomerase function remains obscure. Using a suite of single-molecule approaches, we examined the torsional impact on supercoiling relaxation of both naked DNA and chromatin by eukaryotic topoisomerase II (topo II). We observed that topo II was at least ~ 50-fold more processive on plectonemic DNA than previously estimated, capable of relaxing > 6000 turns. We further discovered that topo II could relax supercoiled DNA prior to plectoneme formation, but with a ~100-fold reduction in processivity; strikingly, the relaxation rate in this regime decreased with diminishing torsion in a manner consistent with the capture of transient DNA loops by topo II. Chromatinization preserved the high processivity of the enzyme under high torsional stress. Interestingly, topo II was still highly processive (~ 1000 turns) even under low torsional stress, consistent with the predisposition of chromatin to readily form DNA crossings. This work establishes that chromatin is a major stimulant of topo II function, capable of enhancing function even under low torsional stress.

A New Finding on Magnetic Resonance Imaging for Diagnosis of Hemifacial Spasm with High Accuracy and Interobserver Correlation.

Among patients with clinical hemifacial spasm (HFS), imaging exams aim to identify the neurovascular conflict (NVC) location. It has been proven that the identification in the preoperative exam increases the rate of surgical success. Despite the description of specific magnetic resonance image (MRI) acquisitions, the site of neurovascular compression is not always visualized. The authors describe a new MRI finding that helps in the diagnosis of HFS, and evaluate the sensitivity, specificity, and interobserver correlation of the described sign. A cross-sectional study including cases of hemifacial spasm treated surgically from 1 August 2011 to 31 July 2021 was performed. The MRIs of the cases were independently evaluated by two experienced neuroradiologists, who were blinded regarding the side of the symptom. The neuroradiologists were assigned to evaluate the MRIs in two separate moments. Primarily, they evaluated whether there was a neurovascular conflict based on the standard technique. Following this initial analysis, the neuroradiologists received a file with the description of the novel sign, named Prevedello Sign (PS). In a second moment, the same neuroradiologists were asked to identify the presence of the PS and, if it was present, to report on which side. A total of 35 patients were included, mostly females (65.7%) with a mean age of 59.02 (+0.48). Since the 35 cases were independently evaluated by two neuroradiologists, a total of 70 reports were included in the analysis. The PS was present in 66 patients (sensitivity of 94.2%, specificity of 91.4% and positive predictive value of 90.9%). When both analyses were performed in parallel (standard plus PS), the sensitivity increased to 99.2%. Based on the findings of this study, the authors conclude that PS is helpful in determining the neurovascular conflict location in patients with HFS. Its presence, combined with the standard evaluation, increases the sensitivity of the MRI to over 99%, without increasing risks of harm to patients or resulting in additional costs.

Chromatinization modulates topoisomerase II processivity.

Type IIA topoisomerases are essential DNA processing enzymes that must robustly and reliably relax DNA torsional stress. While cellular processes constantly create varying torsional stress, how this variation impacts type IIA topoisomerase function remains obscure. Using multiple single-molecule approaches, we examined the torsional dependence of eukaryotic topoisomerase II (topo II) activity on naked DNA and chromatin. We observed that topo II is ~50-fold more processive on buckled DNA than previously estimated. We further discovered that topo II relaxes supercoiled DNA prior to plectoneme formation, but with processivity reduced by ~100-fold. This relaxation decreases with diminishing torsion, consistent with topo II capturing transient DNA loops. Topo II retains high processivity on buckled chromatin (~10,000 turns) and becomes highly processive even on chromatin under low torsional stress (~1000 turns), consistent with chromatin's predisposition to readily form DNA crossings. This work establishes that chromatin is a major stimulant of topo II function.

Resection of intradural intramedullary subependymoma of the cervicothoracic spine: 2-dimensional operative video.

This video presents the case of a 44-year-old male with a 2-year history of pain in the left upper extremity that had worsened over the course of the last 6 months with associated weakened grip strength and had extended into his right arm. T2-weighted sagittal and axial MRI demonstrated an expansive nonenhancing solid intramedullary lesion extending from C5 to T1. The patient underwent a C5-T1 laminectomy and laminoplasty with near-complete resection of the intradural intramedullary subependymoma. At 3 months' follow-up, he reported doing well and had experienced significant improvement in motor strength with ongoing therapies.

Effects of engaging fathers and bundling parenting and nutrition interventions on early child development and maternal and paternal parenting in Mara, Tanzania: a factorial cluster-randomized controlled trial.

BACKGROUND: Multicomponent interventions are needed to address the various co-occurring risks that compromise early child nutrition and development. We compared the independent and combined effects of engaging fathers and bundling parenting components into a nutrition intervention on early child development (ECD) and parenting outcomes. METHODS: We conducted a 2×2 factorial cluster-randomized controlled trial across 80 villages in Mara Region, Tanzania, also known as EFFECTS (Engaging Fathers for Effective Child Nutrition and Development in Tanzania; ClinicalTrials.gov, NCT03759821). Households with children under 18 months of age residing with their mother and father were enrolled. Villages were randomly assigned to one of five groups: a nutrition intervention for mothers, a nutrition intervention for couples, a bundled nutrition and parenting intervention for mothers, a bundled intervention for couples, and a standard-of-care control. Interventions were delivered by trained community health workers through peer groups and home visits over 12 months. Mothers, fathers, and children were assessed at baseline, midline, and endline or postintervention. We used a difference-in-difference approach with intention-to-treat analysis to estimate intervention effects on ECD (Bayley Scales of Infant and Toddler Development, third edition) and maternal and paternal parenting and psychosocial well-being. RESULTS: Between October 29, 2018, and May 24, 2019, 960 households were enrolled (n = 192 per arm). Compared to nutrition interventions, bundled interventions improved children's cognitive (ß = .18 [95% CI: 0.01, 0.36]) and receptive language development (ß = .23 [0.04, 0.41]). There were no differences between interventions for other ECD domains. Compared to nutrition interventions, bundled interventions achieved additional benefits on maternal stimulation (ß = .21 [0.04, 0.38]) and availability of home learning materials (ß = .25 [0.07-0.43]) and reduced paternal parenting distress (ß = -.34 [-0.55, -0.12]). Compared to interventions with mothers only, interventions that engaged fathers improved paternal stimulation (ß = .45 [0.27, 0.63]). CONCLUSIONS: Jointly bundling parenting components into nutrition interventions while also engaging both mothers and fathers is most effective for improving maternal and paternal parenting and ECD outcomes.

Effects of a Parenting and Nutrition Intervention on Siblings: A Cluster-RCT.

OBJECTIVES: The majority of the evidence about the effectiveness of early parenting and nutrition interventions pertains to 1 targeted index child in a given household. We evaluated whether nontargeted sibling children benefited from a bundled parenting and nutrition intervention. METHODS: We designed a sub-study within a broader cluster-randomized trial that evaluated the effects of engaging both mothers and fathers and bundling parenting and nutrition interventions in Mara, Tanzania. Trained community health workers delivered interventions to parents through peer groups and home visits. Interventions encompassed various content including responsive parenting, infant and young child feeding, and positive couples' relationships. The main trial enrolled mothers and fathers and 1-index children <18 months of age in 80 clusters. Between June and July 2021, in 32 clusters (16 intervention, 16 control), we reenrolled 222 households (118 intervention, 104 control) from the main trial that had another child <6 years of age (ie, sibling to the index child). We compared caregiving practices and child development and nutrition outcomes among siblings in intervention versus control households. RESULTS: Compared with control siblings, intervention siblings had improved expressive language development (ß = 0.33 [95% confidence interval: 0.03 to 0.62]) and dietary intake (ß = 0.52 [0.10 to 0.93]) and reduced internalizing behaviors (ß = -0.56 [-1.07 to -0.06]). Intervention caregivers reported greater maternal stimulation (ß = 0.31 [0.00 to 0.61]) and paternal stimulation (ß = 0.33 [0.02 to 0.65]) and displayed more responsive caregiving behaviors (ß = 0.40 [0.09 to 0.72]) with sibling children. CONCLUSIONS: A father-inclusive, bundled parenting and nutrition intervention can achieve positive spillover effects on sibling children's developmental and nutritional outcomes.

Intergenerational transmission of intimate partner violence among women: Evidence from the 2017 Philippines National Demographic and Health Survey.

Intimate partner violence (IPV) substantially harms women's overall health worldwide. The intergenerational cycle of IPV among women remains underexplored from the perspective of victimization and perpetration, and by types of subsequent IPV. The 2017 Philippines National Demographic and Health Survey dataset of 12,248 currently in-union (married or cohabiting) women aged 15 to 49 were utilized in this study. The main exposure variable was measured by the question: "as far as you know, did your father ever beat your mother?". Multivariate logistic regression was performed to investigate the association between being ever exposed to parental IPV and (1) women's IPV victimization (by types: any, physical, sexual, and emotional) and (2) IPV perpetration (physical) by women against their husbands or male partners. Further, multinomial logistic regression examined the association between exposure to parental IPV and the experience of being an IPV victim only, perpetrator only, or both. We have found that women who were exposed to parental IPV were more likely to experience IPV victimization (OR: 2.1, 95% CI: 1.9, 2.4 for any IPV; OR: 2.3, 95% CI: 2.0, 2. for physical IPV; OR: 2.0, 95% CI: 1.6, 2.4 for sexual IPV; and OR: 2.0, 95% CI: 1.8, 2.2 for emotional IPV), and also perpetrate physical IPV themselves (OR: 2.1, 95% CI: 1.9, 2.4) compared to those unexposed to parental IPV. Moreover, women exposed to parental IPV were three times more likely to be both a perpetrator and a victim of IPV (OR: 3.1, 95% CI: 2.7, 3.7), much higher than the odds of being a victim only (OR: 1.9, 95% CI: 1.8, 2.2) or a perpetrator only (OR: 1.9, 95% CI: 1.6, 2.). In summary, exposure to parental IPV was associated with Filipino women being victims and perpetrators of IPV themselves. The integration of violence prevention within parenting and community programs can be considered to prevent the perpetuation of the intergenerational cycle of IPV.

Formative research to inform the future design of a multicomponent fatherhood intervention to improve early child development in Mwanza, Tanzania.

Fathers can influence child development through various pathways, such as via their caregiving behaviors, marital relationships, and their psychosocial wellbeing. However, few parenting interventions have been designed to target these multiple dimensions among fathers with young children in low- and middle-income countries. In June 2022, we conducted qualitative formative research to explore the perceptions surrounding fatherhood and the underlying barriers and enablers to engaged fathering in Mwanza, Tanzania. We completed individual in-depth interviews with 29 fathers and 23 mothers of children under aged 2 years along with 5 community leaders and 3 community health workers. We also completed 10 focus group discussions: 4 with fathers, 2 with mothers, and 4 mixed groups that combined both fathers and mothers. In total, the sample included 120 respondents stratified from across 4 study communities. Data were analyzed using thematic content analysis. Respondents highlighted that poor couples' relationships (e.g., limited male partner support, male dominance in decision-making) and fathers' mental health problems (e.g., parenting stress) were major priorities affecting fathers. Father involvement in parenting, childcare, and household activities were generally low. These dimensions of fatherhood were interlinked (e.g., poor paternal mental health constrained marital relationships and parenting). A constellation of determinants impacted engaged fathering. Common barriers included poverty, restrictive gender attitudes and norms, men's limited time at home, and inadequate knowledge about caregiving. Key enablers included mutual respect in marital relationships and men's desires to show their love for their families. Our results highlight the cultural relevance and the need for multicomponent strategies that jointly target fathers' caregiving, marital relationships, and psychosocial wellbeing for enhancing nurturing care and promoting early child development in Tanzania. Study findings can be used to inform the design of a future father-inclusive, gender-transformative parenting intervention for engaging and supporting fathers with young children in the local cultural context.

Endoscopic ultrasound guided resection of a Cushing's adenoma invading the medial cavernous sinus wall using the "interdural peeling" technique.

Cushing's adenoma invading the cavernous sinus requires aggressive resection to be cured. MRI is frequently inconclusive for identifying microadenomas, and visualizing the involvement of the medial cavernous sinus is even more challenging. In this video, the authors present a patient with an adrenocorticotropic hormone (ACTH)-producing microadenoma with doubtful left medial cavernous sinus involvement on MRI. She underwent an endoscopic endonasal exploration of the medial compartment of the cavernous sinus. The abnormally thickened wall, confirmed by intraoperative endoscopic endonasal ultrasound, was safely excised using the "interdural peeling" technique. Complete resection of the tumor resulted in normalization of her postoperative cortisol levels and disease remission with no complications. The video can be found here: https://stream.cadmore.media/r10.3171/2023.4.FOCVID22150.
