Absolute lymphocyte counts pretreatment and at 1, 3, 6, and 12 months were evaluated. Kaplan–Meier, Spearman correlation, receiver operating characteristic (ROC) curve, and area under the curve (AUC) analyses were performed.Results: The mean absolute lymphocyte count at baseline was 1.25 ± 0.79 103/μL which was significantly greater than 1 (0.71 ± 0.47 103/μL, p< 0.0001), 3 (0.79 ± 0.77 103/μL, p=0.0003), and 6 (0.81 ± 0.44 103/μL, p=0.0001) months, but not significantly different than 12 (0.92 ± 0.8 103/μL, p=0.12) months post treatment. There was a modest negative correlation between NLD and lymphocyte count at 1 month (rho= − 0.216, p=0.03), which strengthened at 3 months post treatment (rho= − 0.342, p=0.008). AUC of ROC analysis between absolute lymphocyte count ≤ 1 103/μL or > 1 103/μL at 1, 3, 6, and 12 months post treatment was 0.625, 0.676, 0.560, and 0.794, respectively. Univariate analysis of overall survival when separating patients by a lymphocyte count of ≤ 1 103/μL and > 1 103/μL demonstrated a significant difference at 1 (HR: 0.56, 95% CI: 0.33– 0.95, p=0.03), 3 (HR: 0.41, 95% CI: 0.18– 0.94, p=0.035) and 6 (HR: 0.36, 95% CI: 0.17– 0.77, p=0.008) months post treatment, but not pretreatment or at 12 months.Conclusion: NLD may correlate with lymphocyte depression at 1 and 3 months and lymphopenia may portend a worse overall survival in the post treatment setting.Keywords: hepatocellular carcinoma, transarterial radioembolization, lymphocytes

Pre- and post-treatment laboratory and treatment outcome variables were collected. Objective radiologic response (ORR), progression-free survival (PFS), and overall survival (OS) were evaluated. Patients were categorized into above and below median scores and compared.Results: The median pretreatment NLR, PLR, ALRI, SII, and lymphocyte count were 2.7 (range: 0.4– 55), 88.3 (range: 0.1– 840), 71.8 (range: 0.1– 910), 238.1 (range: 0.1– 5150.8), and 1 (range: 0.1– 5.2) 103/μL, respectively. Patients with above median ALRI scores were less likely to achieve an ORR as compared to those with below median ALRI values (132 (132/163, 81%) vs 150 (150/163, 92%), p = 0.004). On univariate analysis, patients with above median pretreatment NLR (HR 1.41, 95% CI: 1.09– 1.83, p = 0.01) and below median lymphocyte count (HR 0.69, 95% CI: 0.53– 0.92, p = 0.01) had significantly worse PFS. The relationship between PFS and NLR (p = 0.08) as well as lymphocytes (p = 0.20) no longer remained on multivariate analysis. On univariate analysis, below median pretreatment NLR (HR 1.72, 95% CI: 1.2– 2.45, p = 0.003) and ALRI (HR 1.52, 95% CI: 1.05– 2.2); p = 0.03) as well as above median lymphocyte count (HR 0.48, 95% CI: 0.34– 0.7, p < 0.0001) were associated with improved OS. The significant relationship between lymphocytes and OS remained on multivariate analysis (HR 0.50, 95% CI: 0.28– 0.9, p = 0.02), but the relationship with NLR (p = 0.94) did not persist.Conclusion: NLR is predictive of PFS and OS in patients with HCC undergoing TACE and may be superior to other inflammatory scores (PLR, ALRI, and SII) in this setting. However, lymphocyte count may be most predictive of OS.Keywords: hepatocellular carcinoma, chemoembolization, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, aspartate-aminotransferase-to-lymphocyte ratio, systemic-inflammation index

- Abstract
Objective: Research is available on improved coverage and practices from several large-scale maternal nutrition programmes, but not much is known on change in inequalities. This study analyses wealth and education inequality using Erreygers and Concentration indices for four indicators: adequate iron and folic acid (IFA) consumption, women's dietary diversity, and counselling on IFA and dietary diversity., Design: A pre-test-post-test, control group design., Setting: Maternal nutrition intervention programmes conducted in Bangladesh, Burkina Faso and Ethiopia during 2015-2022., Participants: Recently delivered women (RDW) and pregnant women (PW)., Results: Statistically significant reductions in education inequality were observed for adequate IFA consumption, counselling on IFA and dietary diversity in intervention areas of Bangladesh and for adequate IFA consumption in intervention areas of Burkina Faso.A significant decrease in wealth inequality was observed for adequate IFA consumption in the intervention areas of Bangladesh, whereas a significant increase was observed in the non-intervention areas for counselling on IFA in Ethiopia and for dietary diversity in Burkina Faso., Conclusion: The results can be attributed to the extensive delivery system at community level in Bangladesh and being predominantly facility-based in Burkina Faso and Ethiopia. COVID-19 disruptions (in Burkina Faso and Ethiopia) and indicator choice also had a role in the results.The main takeaways for nutrition programmes are as follows: (a) assessing inequality issues through formative studies during designing, (b) monitoring inequality indicators during implementation, (c) diligently addressing inequality through targeted interventions, setting aside resources and motivating frontline workers to reduce disparities and (d) making inequality analysis a routine part of impact evaluations.

- Abstract
Background: Intrahepatic cholangiocarcinoma (ICC) is a rare primary hepatic malignancy. One of the treatment strategies which has shown some promise is transarterial radioembolization (TARE). However, data on dose thresholds, arguably the most important aspect of the procedure itself, is still limited. The study aims to evaluate the relationship between dose to tumor and radiologic response in intrahepatic cholangiocarcinoma patients undergoing transarterial radioembolization., Methods: Twenty-patients who underwent treatment for 26 tumors were retrospectively reviewed. Radiologic response at 3-month was evaluated and post yttrium-90 bremsstrahlung single photon emission computerized tomography computed tomography was evaluated to determine tumor dose. Other factors such as particle load and activity per particle were evaluated., Results: The mean tumor dose for those with progressive disease or stable disease, partial response, and complete response (CR) by European Association for the Study of Liver (EASL) criteria for the glass cohort was 294±0, 465.4±292.4 and 951.8±666.5 Gy respectively (P=0.039). A receiver operating characteristic (ROC) curve analysis of tumor dose demonstrated an area under the curve (AUC) of 0.738 (P=0.038) with Youden-index analysis demonstrated a cutoff point of >541.7 Gy (sensitivity: 55.56%; specificity: 92.86%) for the glass cohort. Significantly longer survival was noted in those who achieved a CR [HR: 4.79 (95% CI: 1.41-16.25)] and those treated with glass as compared to resin [HR: 5.02 (95% CI: 1.23-20.55), P=0.025]. Of the 17 treatments in 13 patients which were done concomitantly with chemotherapy 7/17 (41.2%) required a delay in chemotherapy, however all patients reinitiated chemotherapy after a delay., Conclusions: There appears to be a relationship between tumor dose and radiologic response, with this study suggesting a target of ≥541.7 Gy being warranted in patients receiving treatment with glass microspheres., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jgo.amegroups.com/article/view/10.21037/jgo-23-210/coif).

- Abstract
Background: Alive & Thrive supported the Government of Burkina Faso to strengthen the provision of iron and folic acid (IFA) supplementation and interpersonal counseling on maternal nutrition and breastfeeding through antenatal care (ANC) services and community-based contacts in 2 regions., Objectives: We assessed the impacts of intensified nutrition interventions during ANC compared with standard ANC services on intervention coverage and maternal nutrition practices., Methods: A cluster-randomized evaluation compared 40 health center catchment areas in intervention areas with 40 in control areas. Repeated cross-sectional surveys in 2019 and 2021 (960 pregnant women and 1920 women with children 0-5 mo of age per survey round) provided data on impact indicators, intervention exposure, and other factors. We derived difference-in-difference (DID) effect estimates, adjusted for geographic clustering, for maternal dietary diversity, IFA consumption, and early breastfeeding practices., Results: More women in intervention areas had 4+ ANC visits (DID: 8.3 percentage points [pps]) and started ANC during the first trimester (DID: 10.5 pp), compared with control areas. Improvements were achieved in exposure to nutrition counseling on dietary diversity (DID: 44.4 pp), food quantity (DID: 42.9 pp), adequate weight gain (DID: 35.1 pp), and breastfeeding (DID: 25.9 pp). Women in intervention areas consumed more IFA supplements during pregnancy (DID: 21 tablets). Early initiation of and exclusive breastfeeding also improved (DID: 17.0 and 8.3 pp, respectively). However, dietary diversity (4 out of 10 food groups) and mean probability of adequacy of micronutrient intake (14%) among pregnant women remained low in both areas., Conclusions: Strengthening maternal nutrition interventions delivered through government ANC services was feasible and effective in improving maternal nutrition practices. Continued efforts to strengthen the delivery and use of maternal nutrition services may be required for greater behavior changes, and to address family support, social norms, and other factors to improve women's diets during pregnancy., (Copyright © 2023 The Authors.

- Abstract
Background: Adolescence is a critical period of physical and psychological development, especially for girls, because poor nutrition can affect their wellbeing as well as that of their children. We aimed to assess the feasibility and impact of a package of nutrition education interventions delivered through public primary schools on the diets of adolescent girls in Ethiopia., Methods: In this non-masked, cluster-randomised, controlled trial, primary schools (clusters) in the Southern Nations, Nationalities, and People's Region and Somali region of Ethiopia were randomly allocated to the intervention group (nutrition information provided during flag ceremonies, classroom lessons, school club meetings, peer group mentoring, BMI measurement and counselling, and parent-teacher meetings) or the control group (standard academic curriculum on health and nutrition) by use of computer-generated pseudo-random numbers. Duration of the school-based interventions was 4 months, and the key messages were related to dietary diversity (eating a variety of foods), energy adequacy (eating breakfast and healthy snacks), and healthy food choices (avoiding junk foods). Adolescent girls were eligible for participation if aged 10-14 years and enrolled in grades 4-8 in a study school. Data were collected with two independent cross-sectional surveys: baseline before the start of implementation and endline 1·5 years later. The primary outcome of impact was dietary diversity score, defined as the number of food groups (out of ten) consumed over the previous 24 h using a list-based method, and minimum dietary diversity, defined as the proportion of girls who consumed foods from at least five of the ten food groups, in the intention-to-treat population. We also assessed intervention exposure as a measure of feasibility. We estimated intervention effects using linear regression models for mean differences at endline, with SEs clustered at the school level, and controlled for adolescent age, region, household food security, and wealth. The trial is registered with ClinicalTrials.Gov, NCT04121559, and is complete., Findings: 27 primary schools were randomly allocated to the intervention group and 27 to the control group. Between March 22 and April 29, 2021, 536 adolescent girls participated in the endline survey (270 in the intervention group and 266 in the control group), with median age of 13·3 years (IQR 12·1-14·0). At endline, the dietary diversity score was 5·37 (SD 1·66) food groups in the intervention group and 3·98 (1·43) food groups in the control group (adjusted mean difference 1·33, 95% CI 0·90-1·75, p<0·0001). Increased minimum dietary diversity was also associated with the intervention (182 [67%] of 270 in the intervention group vs 76 [29%] of 266 in the control group; adjusted odds ratio 5·37 [95% CI 3·04-9·50], p<0·0001). 256 (95%) of 270 adolescent girls in the intervention group were exposed to at least one of the five in-school intervention components., Interpretation: Integrating nutrition interventions into primary schools in Ethiopia was feasible and increased dietary diversity incrementally among adolescent girls, but could be limited in changing other food choice behaviours, such as junk food consumption, based on nutrition education alone., Funding: Bill & Melinda Gates Foundation., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2023 The Author(s).

- Abstract
Background: Dolutegravir (DTG) is a recommended first-line regimen for all people with Human Immunodeficiency Virus (HIV) infection. Initial findings from Botswana, a country with no folate fortification program, showed an elevated prevalence of neural tube defects (NTDs) with peri-conceptional exposure to DTG. Here we explore whether a low folate diet influences the risk of DTG-associated foetal anomalies in a mouse model., Methods: C57BL/6 mice fed a folate-deficient diet for 2 weeks, were mated and then randomly allocated to control (water), or 1xDTG (2.5 mg/kg), or 5xDTG (12.5 mg/kg) both administered orally with 50 mg/kg tenofovir disoproxil fumarate 33.3 mg/kg emtricitabine. Treatment was administered once daily from gestational day (GD) 0.5 to sacrifice (GD15.5). Foetuses were assessed for gross anomalies. Maternal and foetal folate levels were quantified., Findings: 313 litters (103 control, 106 1xDTG, 104 5xDTG) were assessed. Viability, placental weight, and foetal weight did not differ between groups. NTDs were only observed in the DTG groups (litter rate: 0% control; 1.0% 1xDTG; 1.3% 5xDTG). Tail, abdominal wall, limb, craniofacial, and bleeding defects all occurred at higher rates in the DTG groups versus control. Compared with our previous findings on DTG usage in folate-replete mouse pregnancies, folate deficiency was associated with higher rates of several defects, including NTDs, but in the DTG groups only. We observed a severe left-right asymmetry phenotype that was more frequent in DTG groups than controls., Interpretation: Maternal folate deficiency may increase the risk for DTG-associated foetal defects. Periconceptional folic acid supplementation could be considered for women with HIV taking DTG during pregnancy, particularly in countries lacking folate fortification programs., Funding: This project has been funded by Federal funds from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Department of Health and Human Services, under Contract No. HHSN275201800001I and award #R01HD104553.

- Abstract
Over the last several decades, a number of new treatment options for patients with hepatocellular carcinoma (HCC) have been developed. While treatment decisions for some patients remain clear cut, a large numbers of patients have multiple treatment options, and it can be hard for multidisciplinary teams to come to unanimous decisions on which treatment strategy or sequence of treatments is best. This article reviews the available data with regard to two treatment strategies, immunotherapies and locoregional therapies, with a focus on the potential of locoregional therapies to be combined with checkpoint inhibitors to improve outcomes in patients with locally advanced HCC. In this review, the available data on the immunomodulatory effects of locoregional therapies is discussed along with available clinical data on outcomes when the two strategies are combined.

- Abstract
The purpose of this study was to retrospectively evaluate the safety and efficacy of cryoablation and compare the outcomes with those of percutaneous ethanol injection (PEI) for the treatment of metastatic cervical lymph nodes (CLNs) in patients with thyroid cancer. The study included 24 patients with 47 CLNs treated with PEI and 7 patients with 11 CLNs treated with cryoablation. Three of 7 (42.9%) patients did not respond to PEI and progressed to cryoablation. There were more local recurrences in CLNs treated with PEI (7/47, 14.9%) compared with cryoablation (0/11, 0%), but this did not reach significance (P = .33). There was no difference in mild/moderate (3/24, 12.5% vs 2/7, 28.6%; P = .31) or severe (1/24, 4.2% vs 0/7, 0%; P = 1) adverse events in the PEI and cryoablation cohorts. The number of treatments required for CLNs treated with PEI (2 ± 1.1) was significantly greater than those for CLNs treated with cryoablation (1 ± 0) (P = .002). These limited data suggest that the treatment of metastatic CLNs with cryoablation or PEI may both be safe and effective; however, further data are needed to confirm superiority of cryoablation., (Copyright © 2022 SIR.

- Abstract
Purpose: To determine the accuracy and clinical significance of planar scintigraphy lung shunt fraction (PLSF) and single-photon emission computerized tomography (SPECT) computed tomography (CT) lung shunt fraction (SLSF) before Y-90 transarterial radioembolization., Materials and Methods: Seventy patients (46 men, 24 women; mean age, 64 ± 9.5 [SD] years) who underwent 83 treatments with Y-90 transarterial radioembolization for primary or secondary malignancies of the liver with a PLSF ≥ 7.5% were retrospectively evaluated. The patients mapping technetium 99 m (Tc-99 m) macroaggregated albumin (MAA) PLSF and SLSF were calculated and compared to the post Y-90 delivery SLSF. A model using modern dose thresholds was created to identify patients who would require dose reduction due to a lung dose ≥ 30 Gy, with patients who required >50% dose reduction considered to be delivery cancelations., Results: A significant difference was found between mean PLSF (14.7 ± 11.6 [SD]%; range: 7.5-84.1%) and mean SLSF (8.7 ± 8.5 [SD]%; range: 1.7-73.5) (P < 0.001). The mean realized LSF (7.1 ± 3 [SD]%; range:1.5-17.6) was significantly less than the PLSF (P <0.001) but not the SLSF (P = 0.07). PLSF significantly overestimated the realized LSF by more than the SLSF (8.5 ± 5.3 [SD] % [range: -0.1-21.7] vs. 0.8 ± 3.6 [SD] % [range: -5-13.2], respectively) (P < 0.001). Based on the clinical significance model, 20 patients (20/83, 24.1%) would have required dose reduction or cancelation when using PLSF but would not require even a dose reduction when using the SLSF. Significantly more deliveries would have been be canceled if PLSF was used as compared to SLSF (22/83 [26.5%] vs. 6/83 [7.2%], respectively) (P < 0.001)., Conclusion: SLSF is significantly more accurate at predicting realized LSF than PLSF and this difference is of clinical significance in a number of patients with a PLSF ≥ 7.5%., Competing Interests: Declaration of Competing Interest SY is a consultant for Boston Scientific.

- Abstract
Purpose: To evaluate the correlation of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), aspartate aminotransferase-to-lymphocyte ratio (ALRI), systemic inflammation index (SII), and lymphocyte count to oncologic outcomes in metastatic colorectal cancer (mCRC) patients undergoing transarterial radioembolization (TARE)., Materials and Methods: All patients undergoing TARE for mCRC were retrospectively reviewed at a single academic institution. A receiver operating characteristics (ROC) curve analysis was performed using a landmark survival point of 12 months, with an area under the curve (AUC) calculated. A cutoff point was determined by Youden's index and used to separate patients for OS and PFS analysis. Cox proportional-hazards models which included pertinent clinical factors were also created to evaluate PFS and OS., Results: In total, 41 patients who underwent 66 TARE treatments were included. A correlation was seen between post-treatment ALRI < 45 (HR: 0.38 (95%CI: 0.17-0.86), p = 0.02) and PFS. Patients with a pretreatment ALRI score < 20 had a significantly longer OS (HR: 0.49 (95%CI: 0.19-0.88), p = 0.02) as did those with a post-treatment lymphocyte count > 1.1 10
9 /L (HR: 0.27 (95%CI: 0.11-0.68), p = 0.005). In multivariate analysis of PFS, post-treatment lymphocyte count (HR: 8.46 (95%CI: 1.14-62.89), p = 0.044) was the only significantly associated inflammatory marker and presence of extrahepatic disease (HR:8.46 (95%CI: 1.14-62.89, p = 0.044) also correlated. Multivariate analysis of OS showed that pretreatment PLR (HR:1.01 (95%CI:1.-1.03), p = 0.02) and post-treatment NLR (HR:0.33 (95%CI:0.14-0.76), p = 0.009), PLR (HR:0.98 (95%CI:0.97-1), p = 0.046), SII (HR:1.04 (95%CI:1.01-1.08), p = 0.014), and lymphocyte count (HR:0.07 (95%CI:0.01-0.16), p = 0.003) were significantly associated., Conclusion: Inflammatory markers may be associated with OS and PFS in mCRC patients undergoing TARE., (© 2022.

- Abstract
The majority of research on linear growth among children is confined to South Asia and focuses on iron and folic acid (IFA) supplementation during pregnancy, without considering malaria prophylaxis. Similarly, there is limited evidence on the association of antenatal IFA supplementation and malaria prophylaxis with neonatal mortality in sub-Saharan Africa (SSA). This study aims to address these gaps. A pooled analysis of demographic and health survey (DHS) data from 19 countries in SSA was conducted to study the association between IFA supplementation and malaria prophylaxis and linear growth and neonatal mortality. Multivariate logistic and linear regression models were used. Malaria prophylaxis was significantly associated with stunting, height-for-age Z scores (HAZ scores), and neonatal mortality, but IFA supplementation was not associated with these outcomes. When women's height and body mass index (BMI) were introduced in the model, a significant association between combined malaria prophylaxis and IFA supplementation was found with HAZ scores only. For severe stunting, no significant association was found with either in the two models. In conclusion, this study underscores the importance of antenatal malaria prophylaxis as a potential intervention for nutrition outcomes (linear growth) and neonatal mortality, as well as the importance of coordinating efforts between malaria and the health and nutrition sectors to improve these outcomes in the countries of SSA.

- Abstract
Integrating nutrition interventions into antenatal care (ANC) requires adapting global recommendations to fit existing health systems and local contexts, but the evidence is limited on the process of tailoring nutrition interventions for health programmes. We developed and integrated maternal nutrition interventions into ANC programmes in Bangladesh, Burkina Faso, Ethiopia and India by conducting studies and assessments, developing new tools and processes and field testing integrated programme models. This paper elucidates how we used information and data to contextualize a package of globally recommended maternal nutrition interventions (micronutrient supplementation, weight gain monitoring, dietary counselling and counselling on breastfeeding) and describes four country-specific health service delivery models. We developed a Theory of Change to illustrate common barriers and strategies for strengthening nutrition interventions during ANC. We used multiple information sources including situational assessments, formative research, piloting and pretesting results, supply assessments, stakeholder meetings, household and service provider surveys and monitoring data to design models of maternal nutrition interventions. We developed detailed protocols for implementing maternal nutrition interventions; reinforced staff capacity, nutrition counselling, monitoring systems and community engagement processes; and addressed micronutrient supplement supply bottlenecks. Community-level activities were essential for complementing facility-based services. Routine monitoring data, rapid assessments and information from intensified supervision were important during the early stages of implementation to improve the feasibility and scalability of models. The lessons from addressing maternal nutrition in ANC may serve as a guide for tackling missed opportunities for nutrition within health services in other contexts., (© 2022 The Authors.

- Abstract
Objectives: To determine the realized tumor to normal ratios (TNRs) in patients undergoing radiation segmentectomies (RS); determine the relationship between TNRs and particle load in transarterial radioembolization (TARE)., Methods: In total, 148 patients who underwent 184 TARE procedures for hepatocellular carcinoma were evaluated. Post treatment SPECT CT bremsstrahlung imaging was analyzed utilizing Simplicit90y™ to determine realized TNR. A model which normalized activity across all RS treatments to a level that would achieve 400 Gy by unicompartmental dosing was created to determine the affect realized TNR would have on tumor absorbed dose., Results: The mean TNR in the setting of RS was 2.88 ± 1.60 and was higher for glass as compared to resin microspheres (3.07 ± 1.68 vs 2.24 ± 1.21, p = 0.01). The TNR was significantly greater in the RS as compared to the lobar deliveries (2.88 ± 1.60 vs 2.16 ± 1.12, p < 0.01). When normalizing the activity of RS treatments to the level required to achieve 400 Gy by unicompartmental calculations, there was found to be significant differences in the predicted tumor absorbed dose when separated by the median tumor dose (601.2 ± 133.3 vs 1146.9 ± 297.5, p < 0.01) or median realized TNR (1119.2 ± 341 Gy vs 635.7 ± 160.2 Gy, p < 0.01). Particle load was found to be associated with TNR on univariate (p < 0.01) and multivariate (p < 0.01) analysis., Conclusion: Significant TNRs are seen in RS and perhaps argue for the use of multi-compartmental dosimetry techniques in this setting and particle load may affect TNR., Key Points: • Tumor to normal ratios were significantly higher in radiation segmentectomies than lobar deliveries. • Tumor to normal ratios were significantly higher when utilizing glass, as compared to resin microspheres. • When creating a model that prescribed the activity required to reach 400 Gy by MIRD, realized tumor dose varied significantly in radiation segmentectomies., (© 2022.

- Abstract
Purpose: To evaluate the ability of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), aspartate aminotransferase-to-lymphocyte ratio (ALRI) and systemic-inflammation index (SII) to predict clinical outcomes in hepatocellular carcinoma (HCC) patients undergoing transarterial radioembolization (TARE)., Materials and Methods: One hundred forty-five patients who underwent treatment of 167 HCCs had their pretreatment and 1 month post treatment laboratory values evaluated. Overall survival (OS), progression-free survival (PFS) and local PFS models were performed with patients separated by median inflammatory scores., Results: The median pretreatment NLR, PLR, ALRI and SII were 3.0 (range: 0.5-176), 104.4 (range: 25-830), 55.7 (range: 7.5-2090) and 360.2 (range: 51.1-7207.8), respectively. While the median post treatment NLR, PLR, ALRI and SII were 6.2 (range: 0.4-176), 180 (range: 35-2100), 125 (range: 15.9-5710) and 596.8 (range: 28.9-19,320), respectively. OS models showed significant differences when separating the groups by median post treatment NLR (p = 0.003) and SII (p = 0.003). Multivariate Cox regression models for OS with all pre and post treatment inflammatory markers (log-scale) as well as tumor size, AFP and Child-Pugh score showed significant pretreatment NLR [HR: 0.22 (95% CI:0.06-0.75), p = 0.016] and SII [3.52 (95% CI: 1.01-12.3), p = 0.048], as well as post treatment NLR [6.54 (95% CI: 1.57-27.2), p = 0.010] and SII [0.20 (95% CI: 0.05-0.82), p = 0.025] association. The post treatment ALRI (p = 0.010) correlated with PFS while, post treatment NLR (p < 0.001), ALRI (p = 0.024) and SII (p = 0.005) correlated with local PFS., Conclusion: Pretreatment and post treatment NLR and SII may be associated with OS and post treatment ALRI may be associated with both PFS and local PFS in HCC patients undergoing TARE., (© 2022.

- Abstract
Antenatal care (ANC) is the largest health platform globally for delivering maternal nutrition interventions (MNIs) to pregnant women. Yet, large missed opportunities remain in nutrition service delivery. This paper examines how well evidence-based MNIs were incorporated in national policies and programs in Bangladesh, Burkina Faso, Ethiopia and India. We compared the nutrition content of ANC protocols against global recommendations. We used survey data to elucidate the coverage of micronutrient supplementation, weight gain monitoring, dietary and breastfeeding counselling. We reviewed literature, formative research and program assessments to identify barriers and enabling factors of service provision and maternal nutrition practices. Nutrition information in national policies and protocols was often fragmented, incomplete and did not consistently follow global recommendations. Nationally representative data on MNIs in ANC was inadequate, except for iron and folic acid supplementation. Coverage data from subnational surveys showed similar patterns of strengths and weaknesses. MNI coverage was consistently lower than ANC coverage with the lowest coverage of weight gain monitoring and variable coverage of dietary and breastfeeding counselling. Key common factors associated with coverage were micronutrient supply disruptions; suboptimal counselling on maternal diet, weight gain, and breastfeeding; and limited or no record keeping. Adherence of women to micronutrient supplementation and dietary recommendations was low and associated with late and too few ANC contacts, poor maternal knowledge and self-efficacy, and insufficient family and community support. Models of comprehensive nutrition protocols and health systems that deliver maternal nutrition services in ANC are urgently needed along with national data systems to track progress., (© 2021 The Authors.

- Abstract
Purpose: The purpose of this study was to determine the local progression rate and identify factors that may predict local progression, in patients who achieve a complete response (CR) radiologically after undergoing transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC)., Materials and Methods: One-hundred-forty-seven patients, who achieved CR of 224 HCCs after TACE, were retrospectively reviewed. There were 109 men and 38 women with a mean age of 61.6 ± 6.8 (SD) years (range: 45.4-86.9 years). Logistic mixed-effects and Cox regression models were used to evaluate associations between clinical factors and local progression., Results: A total of 75 patients (75/147; 51%) and 99 (99/224,44.2%) lesions showed local progression at a median of 289.5 days (Q1: 125, Q3: 452; range: 51-2245 days). Pre-treatment, international normalization ratio (INR) (1.17 ± 0.15 [SD] vs. 1.25 ± 0.16 [SD]; P <0.001), model for end-stage liver disease (9.4 ± 2.6 [SD] vs. 10.6 ± 3.2 [SD]; P = 0.010) and Child-Pugh score (6 ± 1 [SD] vs. 6.4 ± 1.3 [SD]; P = 0.012) were significantly lower while albumin serum level (3.4 ± 0.62 [SD] vs. 3.22 ± 0.52 [SD]; P = 0.033) was significantly greater in those who showed local progression as compared to those who did not. In terms of local-recurrence free survival, the number of TACE treatments (hazard ratio [HR]: 2.05 [95% CI: 1.57-2.67]; P<0.001), INR (HR: 0.13 [95% CI: 0.03-0.61]; P = 0.010) and type of TACE (P = 0.003) were significant. Patients with local progression on any tumor did not differ from those who did in terms of overall survival (P = 0.072), however, were less likely to be transplanted (20/75, 26.7%) than those who did not (33/72; 36.1%) (P = 0.016)., Conclusion: A significant number of patients who achieve CR of HCC after TACE have local progression. This emphasizes the importance of long-term follow up., (Copyright © 2022 Société française de radiologie. All rights reserved.)

- Abstract
Suboptimal dietary intake is a critical cause of poor maternal nutrition, with several adverse consequences both for mothers and for their children. This study aimed to (1) assess maternal dietary patterns in India; (2) examine enablers and barriers in adopting recommended diets; (3) review current policy and program strategies to improve dietary intakes. We used mixed methods, including empirical analysis, compiling data from available national and subnational surveys, and reviewing literature, policy, and program strategies. Diets among pregnant women are characterized by low energy, macronutrient imbalance, and inadequate micronutrient intake. Supply- and demand-side constraints to healthy diets include food unavailability, poor economic situation, low exposure to nutrition counselling, food restrictions and taboos, adverse family influence and gender norms, and gaps in knowledge. Intervention strategies with potential to improve maternal diets include food-based programs, behavior change communication, and nutrition-sensitive agriculture interventions. However, strategies face implementation bottlenecks and limited effectiveness in real-world at-scale impact evaluations. In conclusion, investments in systems approaches spanning health, nutrition, and agriculture sectors, with evaluation frameworks at subnational levels, are needed to promote healthy diets for women.

- Abstract
Background: Dolutegravir (DTG) is a preferred regimen for all people with HIV including pregnant women, but its effects on the fetus are not fully understood. Periconceptional exposure to DTG has been associated with increased rates of neural tube defects (NTDs), although it is unknown whether this is a causal relationship. This has led to uncertainty around the use of DTG in women of reproductive potential., Methods: Pregnant C57BL/6J mice were randomly allocated to control (water), 1x-DTG (2.5 mg/kg-peak plasma concentration ~3000 ng/ml - therapeutic level), or 5x-DTG (12.5 mg/kg-peak plasma concentration ~12,000 ng/ml - supratherapeutic level), once daily from gestational day 0.5 until sacrifice. DTG was administered with 50 mg/kg tenofovir+33.3 mg/kg emtricitabine. Fetal phenotypes were determined, and maternal and fetal folate levels were quantified by mass-spectrometry., Findings: 352 litters (91 control, 150 1x-DTG, 111 5x-DTG) yielding 2776 fetuses (747 control, 1174 1x-DTG, 855 5x-DTG) were assessed. Litter size and viability rates were similar between groups. Fetal and placenta weights were lower in the 1x-DTG vs. control. Placental weight was higher in the 5x-DTG vs. control. Five NTDs were observed, all in the 1x-DTG group. Fetal defects, including microphthalmia, severe edema, and vascular/bleeding defects were more frequent in the 1x-DTG group. In contrast, defect rates in the 5x-DTG were similar to control. Fetal folate levels were similar between control and 1x-DTG, but were significantly higher in the 5x-DTG group., Interpretation: Our findings support a causal relationship of DTG at therapeutic doses with increased risk for fetal defects, including NTDs at a rate that is similar that reported in the Tsepamo study for women exposed to DTG-based ART from conception. The non-monotonic dose-response relationship between DTG and fetal anomalies could explain the previous lack of fetal toxicity findings from pre-clinical DTG studies. The fetal folate levels suggest that DTG is unlikely to be an inhibitor of folate uptake., Funding: This project has been funded with Federal funds from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Department of Health and Human Services, under Contract No. HHSN275201800001I., Competing Interests: Declaration of Competing Interest The authors have no competing interests relating to this study.

- Abstract
Purpose: To report the precision of a technique of measuring the PZ thickness on T2-weighted MRI and report normal parameters in patients with normal-sized prostates. We also wanted to establish the mean and second standard deviations (2SD) above and below the mean as criteria for abnormally narrow or expanded PZ thickness., Methods: Of the initial 1566 consecutive cohort referred for evaluation for carcinoma based on elevated PSA (prostate specific antibody) or DRE (digital rectal examination), 132 separate subjects with normal-sized prostates were selected for this study. Mean age was 58.2 years (15-82). Median serum PSA was 6.2 ng/mL (range 0.3-145). Most were asymptomatic for lower urinary tract symptoms (LUTS). Inclusion criteria in this study required technically adequate T2-weighted MRI and total prostatic volume (TPV) ≤ 25 cc. Exclusion criteria included post-prostatic surgical and radiation patients, patients having had medical management or minimally invasive therapy for BPH, those being treated for prostatitis. Patients with suspected tumor expanding or obscuring measurement boundaries were also not considered. Transition zone (TZ) and peripheral zone (PZ) volumes were determined using the prolate ellipsoid model. Posterolateral measurement of the PZ was obtained at the axial level of maximal transverse diameter of the prostate on a line drawn from the outer boundary of the TZ to the inner boundary of the external prostatic capsule (EPC). The data were normally distributed. Therefore, it was analyzed using the 2-sided student t-test and Pearson product correlation statistic., Results: Mean pooled (composite) measurement for the posterolateral PZ (PLPZ) was 10 mm (CI 9.5-10.5 mm) with SD of 2.87 mm. Means were statistically the same for the 2 observers (p = 0.75). Pearson correlation between the two observers was 0.63., Conclusions: In a prostate ≤ 25 cc volume , the posterolateral PZ should be no thicker than 15.8 mm and averages 10.0 mm when measured in the maximal axial plane on MRI. These norms were independent of age or use of endorectal coil. The technique measurement demonstrated clinically useful precision.

- Abstract
Objective: To review and describe imaging findings on multidetector computed tomography in the early postoperative period after cytoreductive surgery with concomitant hyperthermic intraperitoneal chemotherapy (CRS + HIPEC)., Methods: This was a retrospective review of consecutive patients undergoing early (≤60 days) postoperative abdominopelvic multidetector computed tomography scans after CRS + HIPEC from 2014 to 2018 at a single institution. Two radiologists separately assessed bowel wall thickening, bowel wall enhancement, bowel dilation, ascites, and pleural effusion(s) and identified any other significant finding(s)., Results: Thirty-two patients met the inclusion criteria. The majority of patients demonstrated bowel wall thickening (53%; n = 17) and ascites (72%; n = 23), whereas postoperative ileus (35%; n = 10), pleural effusion(s) (24%; n = 7), and bowel wall hyperenhancement (6%; n = 1) were less common. Significant findings included anastomotic leak/perforation (13%; n = 4), fistula (13%; n = 4), abscess (13%; n = 4), and bladder leak (6%; n = 2)., Conclusions: Multidetector computed tomography is an excellent imaging modality to identify common postoperative findings as well as complications following CRS + HIPEC.

- Abstract
Purpose: To evaluate the oncologic outcomes and complication profile in nonalcoholic steatohepatitis (NASH)-induced cirrhosis leading to hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE)., Materials and Methods: Two hundred and twenty patients who underwent treatment of 353 HCCs were retrospectively reviewed, including 30 NASH patients who received TACE for 46 HCCs. Patient charts were evaluated for time to progression (TTP), complications and overall survival (OS). The group was split into NASH and non-NASH cohorts for comparison and additional analyses were done using propensity score matching (PSM)., Results: Patients in the NASH cohort presented with significantly larger lesions (4.9 ± 5.8 cm vs 3.1 ± 2.4 cm, p = 0.05). There was no significant difference in TTP overall [Median NASH 396 days (95% CI 308-526 days) vs non-NASH cohort 307 days (95% CI 272-364), p = 0.25) or after PSM [259 days non-NASH (95% CI 215-490) vs 396 days NASH (95% CI (349-not reached), p = 0.43]. There was a non-significant increased OS in the non-NASH [median 1078 days (95% CI 668-1594)] as compared to the NASH cohort [median 706 days (95% CI 314-not reached)] (p = 0.08) which decreased following PSM [853 days (95% CI 526-1511) non-NASH vs 706 days (95% CI 314-not reached) NASH, p = 0.48]. The number of complications did not differ significantly between the two groups (p = 0.23)., Conclusion: The oncologic outcomes and complication profile of TACE for HCC induced by NASH cirrhosis appear to be similar to that of other etiologies of cirrhosis. NASH patients presented with larger tumors emphasizing the need for early surveillance.

- Abstract
Background: Interaction within mothers' social networks can theoretically diffuse messages from interventions and campaigns into norms and practices for infant and young child feeding (IYCF)., Objectives: We hypothesized that mothers' social networks, diffusion of information, and social norms differed in intensive [intensive interpersonal counseling (IPC), community mobilization (CM), and mass media (MM)] compared with nonintensive (standard IPC and less-intensive CM and MM) intervention areas, were associated with IYCF practices, and partly explained practice improvement., Methods: We conducted household surveys at endline in 2014 and follow-up in 2016 (n = ∼2000 each round). We used multiple regression to test differences and changes in networks, diffusion, and norms within intervention areas. We analyzed paths from intervention exposure to IYCF practices through networks, diffusion, and norms., Results: Mothers' networks were larger in intensive than in nonintensive areas in 2014 and increased in both areas over time [25-38 percentage points (pp)]. The prevalence of receipt of IYCF information was high, with no changes over time in intensive areas but an increase in nonintensive areas (8-16 pp). In both areas, more family members and health workers provided IYCF information over time. Sharing of information increased 17-23 pp in intensive and 11-41 pp in nonintensive areas over time. Perceived descriptive norms improved 8-16 pp in intensive and 17-28 pp in nonintensive areas. Perceived injunctive norms were high in both areas. Breastfeeding practices were associated with networks, diffusion, and norms (OR: 1.6-4.4 times larger comparing highest with lowest quartile). Minimum dietary diversity was associated with larger networks and diffusion (OR: 1.5-2.2) but not with social norms. Indirect paths from intervention exposure to practices explained 34-78% of total effects., Conclusions: Diffusion of IYCF information through social networks, reinforced by positive social norms for messages promoted over time, will contribute to positive changes in IYCF practices that may be achieved and sustained through large-scale social and behavior change interventions.

- Abstract
Alive & Thrive (A&T) provides strategic technical assistance (TA) to develop effective policies; improve maternal, infant, and young child nutrition (MIYCN) programme design and implementation and enhance system capacity to sustain quality MIYCN service delivery at scale. A qualitative assessment was conducted using document review and stakeholder interviews (n = 79) to describe a selection of A&T's TA in six countries and systematically assess the contextual and TA process-related factors that influenced the results achieved and document the lessons learned about MIYCN TA design and implementation. To facilitate the selection of different types of TA, we classified TA into two levels of stakeholder engagement and intensity. Under the Technical Advisor TA category, we assessed A&T's support to strengthen national policy formulation, monitoring, and implementation of the International Code of Marketing of Breast-milk Substitutes. For Capacity Development TA, we assessed A&T support to scale-up maternal nutrition services and to increase strategic use of data. Factors important for TA provision included identifying and engaging with the right people, using evidence to support advocacy and decision-making, using multiple ways to strengthen capacity, developing packages of tools to support programme scale-up, and reinforcing feedback mechanisms to improve service provision and data quality. Challenges included shifts in the political context, poorly functioning health systems, and limited resources to replicate or sustain the progress made. Continued investment in evidence-based and practical TA that strengthens the institutionalization of nutrition across all stakeholders-including government, medical associations, civil society and development partners-is essential. Future TA must support governments to strengthen system capacity for nutrition, including financial and human resource gaps that hamper full scale-up., (© 2024 The Author(s).

- Abstract
Background: Maternal morbidity is common in Bangladesh, where the maternal mortality rate has plateaued over the last 6 years. Maternal undernutrition and micronutrient deficiencies contribute to morbidity, but few interventions have measured maternal outcomes. We compared reported prevalence of antepartum, intrapartum, and postpartum complications among recently delivered women between maternal nutrition intervention and control areas in Bangladesh., Methods and Findings: We conducted a cross-sectional assessment nested within a population-based cluster-randomized trial comparing a nutrition counseling and micronutrient supplement intervention integrated within a structured home-based maternal, newborn, and child health (MNCH) program to the MNCH program alone in 10 sub-districts each across 4 Bangladesh districts. Eligible consenting women, delivering within 42-60 days of enrollment and identified by community-level health workers, completed an interviewer-administered questionnaire detailing the index pregnancy and delivery and allowed review of their home-based care register. We compared pooled and specific reported antepartum, intrapartum, and postpartum complications between study groups using hierarchical logistic regression. There were 594 women in the intervention group and 506 in the control group; overall, mean age was 24 years, 31% were primiparas, and 39% reported facility-based delivery, with no significant difference by study group. There were no significant differences between the intervention and control groups in household-level characteristics, including reported mean monthly income (intervention, 6,552 taka, versus control, 6,017 taka; p = 0.48), having electricity (69.6% versus 71.4%, p = 0.84), and television ownership (41.1% versus 38.7%, p = 0.81). Women in the intervention group had higher recorded iron and folic acid and calcium supplement consumption and mean dietary diversity scores, but reported anemia rates were similar between the 2 groups (5.7%, intervention; 6.5%, control; p = 0.83). Reported antepartum (69.4%, intervention; 79.2%, control; p = 0.12) and intrapartum (41.4%, intervention; 48.5%, control; p = 0.18) complication rates were high and not significantly different between groups. Reported postpartum complications were significantly lower among women in the intervention group than the control group (33.5% versus 48.2%, p = 0.02), and this difference persisted in adjusted analysis (adjusted odds ratio [AOR] = 0.51, 95% CI 0.32-0.82; p < 0.001). For specific conditions, odds of retained placenta (AOR = 0.35, 95% CI 0.19-0.67; p = 0.001), postpartum bleeding (AOR = 0.37, 95% CI 0.15-0.92; p = 0.033), and postpartum fever/infection (AOR = 0.27, 95% CI 0.11-0.65; p = 0.001) were significantly lower in the intervention group in adjusted analysis. There were no significant differences in reported hospitalization for antepartum (49.8% versus 45.1%, p = 0.37), intrapartum (69.9% versus 59.8%, p = 0.18), or postpartum (36.1% versus 29.9%, p = 0.49) complications between the intervention and control groups. The main limitations of this study are outcome measures based on participant report, non-probabilistic selection of community-level workers' catchment areas for sampling, some missing data for variables derived from secondary sources (e.g., dietary diversity score), and possible recall bias for reported dietary intake and supplement use., Conclusions: Reported overall postpartum and specific intrapartum and postpartum complications were significantly lower for women in intervention areas than control areas, despite similar rates of facility-based delivery and hospitalization for reported complications, in this exploratory analysis. Maternal nutrition interventions providing intensive counseling and micronutrient supplements may reduce some pregnancy complications or impact women's ability to accurately recognize complications, but more rigorous evaluation is needed for these outcomes., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: Antenatal care may be a means to reduce food insecurity in pregnancy and postpartum periods., Objective: With the use of a cluster-randomized design, we tested whether participation in nutrition-focused antenatal care intending to improve household knowledge about the importance of nutrition for pregnant and lactating women and encourage allocation of household resources to ensure sufficient quality and quantity of foods, without providing food assistance, would reduce household food insecurity., Methods: Alive & Thrive integrated nutrition interventions into an existing Maternal, Neonatal, and Child Health (MNCH) program in Bangladesh. The nutrition-focused MNCH package was delivered in 10 subdistricts through antenatal care visits with the use of interpersonal communication, community mobilization, and monitoring of weight gain, aiming to improve maternal diet quality, quantity, and micronutrient intake during pregnancy and breastfeeding. The package included components that could reduce food insecurity, measured using the Household Food Insecurity Access Scale. To examine the impact of the nutrition-focused MNCH package compared with the standard MNCH package, we used linear and multinomial logit regression models, adjusted for subdistrict clustering, to test differences at endline in items, domains, and categories of food insecurity, after first confirming no differences at baseline., Results: At baseline, nearly half of households were food insecure. At endline, the groups differed in food insecurity, whether expressed as items, domains, or categories, with food insecurity in the nutrition-focused MNCH group 22 percentage points lower than in the standard MNCH group and 20 percentage points lower than at baseline., Conclusions: Participation in nutrition-focused antenatal care reduced household food insecurity among recently delivered and pregnant women. Integration of social and behavioral nutrition interventions into antenatal care with components that promote food security provides a potentially effective means to reduce food insecurity, without incurring high costs of providing supplemental food, in populations where limited resources can be directed towards accessing adequate and appropriate foods.
