Community-based infant hearing screening: Outcomes of a rural pilot programme.

Community-based universal newborn hearing screening (UNHS) has not been fully realised in South Africa despite the availability of contextually relevant early hearing detection and intervention guidelines. Research has confirmed the feasibility of implementing UNHS programmes in urban contexts; however, limited information exists for rural contexts. The aim of the study was to describe the outcomes in terms of coverage rate, referral rate and follow-up rate of a 1-year UNHS pilot programme implemented at three primary health care (PHC) clinics in the Limpopo province. A descriptive retrospective review of 2 302 audiological records of infants who underwent NHS between July 2014 to June 2015 was conducted. The mean age at first-stage screen was 112 days (16 weeks). The coverage rate was 87% for the infants screened at 3- and 10- days clinic visits and 27% for infants screened at the 6-week immunisation visit. The first-stage referral rate was 33.9% and 8.3% for the overall second stage referral for diagnostic audiology services. The follow-up rate for rescreens at the clinical level was 77%, while for initial diagnostic assessments, it was 26%. Although not all benchmarks were met within the first year of implementation, the high coverage- and low referral rates, especially in the last 6 months, are the first steps in improving the outcomes of the screening programme.Contribution:The findings confirm the feasibility of implementing community-based UNHS programmes in rural areas in South Africa. Regular monitoring and evaluation contribute to the success of screening programmes.

An optimized strategy triggered at the 2nd immunization visit to prevent HIV acquisition by breastfeeding: a phase 2 trial in Burkina Faso (PREVENIR-PEV)

BackgroundMother-to-child transmission of HIV during breastfeeding remains a challenge in low- and middle-income countries (LMIC). A prevention package was initiated during the highly attended 2nd visit of the Expanded Program of Immunisation (EPI-2) to identify the undiagnosed infants living with HIV and reduce the postnatal transmission of infant exposed to HIV.MethodsPREVENIR-PEV is a non-randomized phase II clinical trial conducted at two health centres in Bobo Dioulasso (Burkina Faso). The study recruited mothers living with HIV aged 15 years and older with their singleton breastfed infants. During EPI-2 (at 8 weeks) and upon signature of the informed consent, a point-of-care early infant diagnosis (EID) was performed. HIV exposed uninfected (HEU) infants were followed-up until 12 months of age. High risk HEU infants (i.e., whose maternal viral load ≥ 1000 cp/mL at EPI-2 or M6) received an extended postnatal prophylaxis (PNP) with lamivudine until end of follow-up or the end of breastfeeding.ResultsBetween 4 December 2019 and 4 December 2020, 118 mothers living with HIV-1 were identified, and 102 eligible mother/infant pairs had their infants tested for HIV EID. Six infants were newly diagnosed with HIV, and 96 HEU infants were followed-up for 10 months. Among the participants followed-up, all mothers were prescribed antiretrovirals. All 18 infants eligible for PNP at either EPI-2 or 6 months (M6) were initiated on lamivudine. No HIV transmission occurred, and no serious adverse events were reported in infants receiving lamivudine.ConclusionsThe PREVENIR-PEV prevention package integrated into existing care is safe and its implementation is feasible in a LMIC with a low HIV prevalence. More research is needed to target mother/infant pairs not adhering to the intervention proposed in this trial.Trial registrationNCT03869944; first registered on 11/03/2019.

Effectiveness of Preventive Measures against Malaria in Children

Malaria was a significant global health challenge, particularly affecting children under five years of age in endemic regions. This review examined the effectiveness of various preventive measures against malaria in children, including insecticide-treated nets (ITNs), preventive chemotherapy, intermittent preventive treatment in infants (IPTi), and health education interventions. A systematic literature search across multiple databases to collate and analyze studies assessing the impact of these preventive measures on malaria outcomes in children was carried out and utilized in compiling this review paper. The findings indicated that a combination of these strategies can substantially reduce malaria incidence and associated morbidity in children. ITNs have been shown to provide a protective barrier against mosquito bites, while IPTi effectively reduces malaria cases in infants through timely administration of antimalarial drugs during immunization visits. Additionally, health education interventions have proven effective in increasing awareness and promoting the use of preventive measures among caregivers and communities. Despite the progress made, challenges such as insecticide resistance and access to healthcare services remain critical barriers to achieving optimal malaria control.

A qualitative look at bed net access and use in Burkina Faso, Mozambique, Nigeria, and Rwanda following piloted distributions of dual-active ingredient insecticide-treated nets

BackgroundUniversal coverage with insecticide-treated nets (ITNs) is important for malaria control and elimination. The emergence and intensification of insecticide resistance threatens progress made through the deployment of these interventions and has required the development of newer, more expensive ITN types. Understanding malaria prevention behaviour, including barriers and facilitators to net access and use, can support effective decision-making for the promotion and distribution of ITNs.MethodsIn-depth interviews and focus group discussions were conducted in 3 to 4 villages per district, in 13 districts across Burkina Faso, Mozambique, Nigeria and Rwanda from 2019 to 2022. Interviews were conducted in the local language, translated and transcribed in English, French or Portuguese. Transcripts were coded and analysed using Nvivo and ATLAS.ti.ResultsITNs were obtained from mass distribution campaigns, antenatal care and immunization visits, and purchased on the private market in some locations. While there were divergent perspectives in whether the number of distributed nets were adequate, participants consistently expressed concerns of bias, discrimination, and a lack of transparency with the distribution process. ITNs were frequently used alongside other malaria prevention methods. The primary motivation for use was malaria prevention. While some participants reported using nets nightly throughout the year, other participants reported seasonal use, both due to the perceived higher density of mosquitoes and discomfort of sleeping under a net in the increased heat. Other barriers to consistent net use included activities that take place away from the home, sleeping patterns and arrangements, and sensitivity to the insecticides on the nets.ConclusionsITNs remain an important malaria control intervention. To ensure adequate and increased net access, distribution campaigns should consider family structures, available sleeping spaces, and other bed sharing preferences when identifying the number of nets needed for distribution. In addition, campaigns should allow for multiple options for net distribution points and timing to accommodate households remote to health services. Continuous distribution channels and complimentary distribution through the private sector could help fill gaps in coverage. Solutions are needed for outdoor malaria transmission, including alternative designs for ITNs, and improving access to complementary personal protective measures.

IJCM_25A: Effect of one-to-one counselling of mothers attending an immunization clinic on breastfeeding among infants- A Randomised Controlled Trial

Background: To improve breastfeeding practices, many interventions have been studied at various critical contact points. Our study aimed to improve exclusive breastfeeding by integrating a limited number of counselling sessions with routine immunization visits. Objective: To find out the effect of one-to-one counselling on six months of exclusive breastfeeding among infants attending immunization clinic. Methodology: An open-labelled, randomised controlled trial was conducted from September 2022 in the Immunization clinic at the Urban Health Training Centre of Dept of Community Medicine, UCMS, at Ghazipur, New Delhi. Mother-Child dyads visiting the clinic (child between 1 ½ to 3 ½ months) were recruited for the study based on certain appropriate inclusion and exclusion criteria. One-to-one counselling on breastfeeding and complementary feeding were provided, respectively, in the first visit (at the time of Pentavalent 1 or 2 vaccination,) and the second visit (at the time of Pentavalent 3 vaccination) to the intervention group. The control group received routine care. In the follow-up visit at 9 months for measles vaccination, a final assessment was done for both the groups. Analysis was done based on Intention to treat and per protocol approaches. Results: 92 Mother-child dyads were recruited in the study, of which 46 were randomized each in the intervention and control group. 6 were lost to follow-up on the second visit and 13 on the third (follow-up) visit. At the first visit, 56.5% of the mothers in the intervention group and 63% of mothers in the control group were exclusively breastfeeding. The proportion of mothers who exclusively breastfed their infant till six months of age were 65.2% in the intervention and 39.1% in the control group with an OR of 2.92(1.25, 6.81). Conclusion: One-to-one counselling at an immunization clinic has an effect on increasing rates of exclusive breastfeeding for 6 months.

A Preliminary Trial of an Early Surveillance Program for Autism and Developmental Delays within General Practices

AbstractThere are inequities in engagement with established early childhood developmental surveillance programs, eclipsing disadvantaged families. The current study sought to address this by dovetailing developmental surveillance with immunization visits and other opportunistic contacts with children at general practices). While 53 General Practices were recruited, significant COVID-19 disruptions resulted in only 81 children being screened (both parent-administered and GP completed). Of the 81 children, 11 screened positive and all of them along with 5% of screen negatives (i.e. 4 children) received clinician-administered reference-standard assessment for autism and developmental delay (DD) using Autism Diagnostic Observation Schedule (ADOS), Autism Diagnostic Interview Schedule –Revised (ADI-R), and Mullen Scales of Early Learning (MSEL). All children found by reference-standard assessment to have probable autism and/or DD had screened positive during the screening process, and 90.9% of children who screened positive were found by reference-standard assessment to have probable DD or autism. The findings provide early evidence for the feasibility and usefulness of parent completed and GP administered developmental measures during opportunistic contacts with GPs as a promising method to facilitate early identification of DD or autism.

The mistreatment of women during maternity care and its association with the maternal continuum of care in health facilities

BackgroundMistreatment of childbearing women continues despite global attention to respectful care. In Ethiopia, although there have been reports of mistreatment of women during maternity care, the influence of this mistreatment on the continuum of maternity care remains unclear. In this paper, we report the prevalence of mistreatment of women from various dimensions, factors related to mistreatment and also its association to the continuum of maternity care in health facilities.MethodsWe conducted an institution-based cross-sectional survey among women who gave birth within three months before the data collection period in Western Ethiopia. A total of 760 women participated in a survey conducted face-to-face at five health facilities during child immunization visits. Using a validated survey tool, we assessed mistreatment in four categories and employed a mixed-effects logistic regression model to identify its predictors and its association with the continuum of maternity care, presenting results as adjusted odds ratios (AORs) with their 95% confidence intervals (CIs).ResultsOver a third of women (37.4%) experienced interpersonal abuse, 29.9% received substandard care, 50.9% had poor interactions with healthcare providers, and 6.2% faced health system constraints. The odds of mistreatment were higher among women from the lowest economic status, gave birth vaginally and those who encountered complications during pregnancy or birth, while having a companion of choice during maternity care was associated to reduced odds of mistreatment by 42% (AOR = 0.58, 95% CI: [0.42–0.81]). Women who experienced physical abuse, verbal abuse, stigma, or discrimination during maternity care had a significantly reduced likelihood of completing the continuum of care, with their odds decreased by half compared to those who did not face such interpersonal abuse (AOR = 0.49, 95% CI: [0.29–0.83]).ConclusionsMistreatment of women was found to be a pervasive problem that extends beyond labour and birth, it negatively affects upon maternal continuum of care. Addressing this issue requires an effort to prevent mistreatment through attitude and value transformation trainings. Such interventions should align with a system level actions, including enforcing respectful care as a competency, enhancing health centre functionality, improving the referral system, and influencing communities to demand respectful care.

Evaluation of the prevention of mother-to-child transmission of HIV programs at the second immunization visit in Burkina Faso and Zambia.

Our study aimed to assess the PMTCT indicators in Burkina Faso and Zambia using a patient-orientated innovative strategy based on the second visit in the Expanded Program on Immunization (EPI-2) visit at 6-8 weeks. This was a cross sectional study. We assessed women attending EPI-2 at primary healthcare facilities in Burkina Faso and Zambia with their children about their exposure to PMTCT interventions. For women living with HIV (WLHIV), viral load was measured and their children were tested for HIV DNA using point of care devices. Overall, 25 093 were enrolled from Burkina Faso and 8961 women from Zambia. Almost, all women attended at least one antenatal care visit. Among those aware of their HIV-positive status, 95.8 and 99.2% were on antiretroviral therapy (ART) in Burkina Faso and Zambia, respectively. Among WLHIV on ART, 75 and 79.2% achieved a viral load suppression (viral load <1000 copies/ml) in Burkina Faso and Zambia, respectively. Infant postnatal prophylaxis was administered from birth until EPI-2 to 60.9 and 89.7% of HIV-exposed children in Burkina Faso and Zambia, respectively. In Burkina Faso, only 60 of 192 (31.3%) of HIV-exposed children were sampled at day 42 for early infant diagnosis (EID) and 3 (1.6%) received a result by EPI-2. In Zambia, these figures were 879 of 1465 (64.0%) and 9.9% (145/1465), respectively for HIV-exposed children sampled at birth. This evaluation strategy at EPI-2 visit could strengthen program monitoring and help identifying gaps to be addressed on the last mile towards elimination of MTCT of HIV.

A Community-Based Survey Exploring the Determinants of Invalid, Delayed, and Missed Immunization in Children of Urban Slums of Karachi, Pakistan

In children, the global burden of vaccines-preventable diseases (VPDs) and deaths can be averted by adopting timely immunization practices. Administering immunization to a child within 28 or 30 days of the designated immunization date is referred to as timely immunization. Besides timely immunization, immunization non-compliance (invalid or delayed or missed immunization) increases the risk of various forms of VPDs and death in children, particularly living in urban slums. This study was designed to examine the immunization practices and to measure the determinants of immunization non-compliance in children living in urban slums of Karachi, Pakistan. A community-based retrospective cohort was carried out from October-2018- to August-2019 in six different urban slums of Karachi. Immunization status of children aged less than 2 years was assessed by reviewing their vaccination card. Children from each slum were approached via 30x7 multistage stratified cluster sampling technique. Data of each child was analyzed descriptively and inferentially using statistical software, i.e., Jamovi version 1.2.25. The practice of timely immunization was observed in approximately half of children, i.e., 49.8% (n=457). The immunization rate at birth (first-visit) was 100%, of which 95.7% were timely immunized. Following the second immunization visit, a sharp decline in the immunization rate, including timely immunization rate was observed. Lack of knowledge, childhood illnesses, lack of interest, and vaccines unavailability were the main reasons of immunization non-compliance. However, an increase in paternal education was significantly associated with decreasing the odds of immunization non-compliance. A decrease in the practice of timely immunization is replaced by either invalid and/or delayed and/or missed immunization practices. Thus, timely immunization is crucial for preventing infectious diseases and promoting the health of a child.

Self-scheduling in a Large Multispecialty and Multisite Clinic: A Retrospective, Longitudinal Examination of Multiple Self-Scheduled Visit Types.

Self-scheduling of medical visits is becoming available at many medical institutions. We aimed to examine the self-scheduled visit counts and rate of growth of self-scheduled visits in a multispecialty practice. For 85 weeks extending from January 1, 2022 through August 24, 2023, we examined self-scheduled visit counts for over 1500 self-scheduled visit types. We compared completed self-scheduled visit counts to all scheduled completed visit counts for the same visit types. We collected counts of the most frequently self-scheduled visit types for each week and examined the change over time. We also determined the proportion that each visit type was self-scheduled. There were 20,769 699 completed visits during the course of the study that met the criteria for inclusion. Self-scheduled visits accounted for 4.0% of all completed visits (838 592/20,769 699). Over the 85-week span, self-scheduled visits rose from 3.0% to 5.3% of the total. There were 1887 unique visit types that were associated with completed visits. There were just 6 appointment visit types of the total 1887 self-scheduled visit types that accounted for 50.7% of the total 838 592 self-scheduled visits. Those 6 visit types were a lab blood test visit (19.5%, 163 K visits), two Family Medicine office visit types (13.0%, 109 K visits), a screening mammogram visit type (6.6%, 55 K visits), a scheduled express care visit type (6%, 50 K visits) and a COVID immunization visit type (5.7%, 48 K visits). Twenty-one visit types that were self-scheduled accounted for 75% of the total self-scheduled visits. Four seasonal visits, accounting for 10.6% of the total self-scheduled visits, were responsible for almost all the non-linear change in self-scheduling. Self-scheduling accounted for a small but growing percent of all outpatient scheduled visits in a multispecialty, multisite practice. A wide range of visit types can be successfully self-scheduled.

Measuring quality of facility-based ITN distribution in Ghana

BackgroundContinuous distribution channels are effective methods to deliver malaria interventions such as insecticide treated nets (ITNs) to pregnant women attending antenatal care clinics and children under five attending immunization visits. Facility-based and provider-based checklists were used during supportive supervision visits to measure the quality of facility-based services and interventions. This study looks at ITN distributions at health facilities in Ghana, with the aim of providing insights on how quality can be measured and monitored.MethodsVarious quality improvement approaches for malaria services occur in Ghana. Selected indicators were analysed to highlight the similarities and differences of how the approaches measured how well the channel was doing. Generally, the approaches assessed (1) service data management, (2) logistics data management, and (3) observation of service provision (ITN issuance, malaria education, ITN use and care education). Two approaches used a binary (Yes/No) scale, and one used a Likert scale.ResultsResults showed that most data reported to the national HMIS is accurate. Logistics data management remained an issue at health facilities, as results showed scores below average across facility stores, antenatal care, and immunization. Though the supervision approaches differed, overall results indicated that almost all eligible clients received ITNs, data were recorded accurately and reported on-time, and logistics was the largest challenge to optimal distribution through health facilities.ConclusionThe supervision approaches provided valuable insights into the quality of facility-based ITN distribution. Ghana should continue to implement supportive supervision in their malaria agenda, with additional steps needed to improve reporting of collected data and increase the number of facilities visited for supportive supervision and the frequency. There were various supervision approaches used with no clear guidance on how to measure quality of facility-based ITN distribution, so there is also need for the global community to agree on standardized indicators and approaches to measuring quality of facility-based ITN distribution. Additionally, future studies can review the effect of multiple rounds of supervision visits on the quality of ITN distribution as well as understand the facilitators and barriers to scaling up supervision of facility-based ITN distribution.

Evaluation of a Mobile-Based Immunization Decision Support System for Scheduling Age-Appropriate Vaccine Schedules for Children Younger Than 2 Years in Pakistan and Bangladesh: Lessons From a Multisite, Mixed Methods Study.

Missed opportunities for vaccination (MOVs), that is, when children interact with the health system but fail to receive age-eligible vaccines, pose a crucial challenge for equitable and universal immunization coverage. Inaccurate interpretations of complex catch-up schedules by health workers contribute to MOVs. We assessed the feasibility of a mobile-based immunization decision support system (iDSS) to automatically construct age-appropriate vaccination schedules for children and to prevent MOVs. A sequential exploratory mixed methods study was conducted at 6 immunization centers in Pakistan and Bangladesh. An android-based iDSS that is packaged in the form of an application programming interface constructed age-appropriate immunization schedules for eligible children. The diagnostic accuracy of the iDSS was measured by comparing the schedules constructed by the iDSS with the gold standard of evaluation (World Health Organization-recommended Expanded Programme on Immunization schedule constructed by a vaccines expert). Preliminary estimates were collected on the number of MOVs among visiting children (caused by inaccurate vaccination scheduling by vaccinators) that could be reduced through iDSS by comparing the manual schedules constructed by vaccinators with the gold standard. Finally, the vaccinators' understanding, perceived usability, and acceptability of the iDSS were determined through interviews with key informants. From July 5, 2019, to April 11, 2020, a total of 6241 immunization visits were recorded from 4613 eligible children. Data were collected for 17,961 immunization doses for all antigens. The iDSS correctly scheduled 99.8% (17,932/17,961) of all age-appropriate immunization doses compared with the gold standard. In comparison, vaccinators correctly scheduled 96.8% (17,378/17,961) of all immunization doses. A total of 3.2% (583/17,961) of all due doses (across antigens) were missed in age-eligible children by the vaccinators across both countries. Vaccinators reported positively on the usefulness of iDSS, as well as the understanding and benefits of the technology. This study demonstrated the feasibility of a mobile-based iDSS to accurately construct age-appropriate vaccination schedules for children aged 0 to 23 months across multicountry and low- and middle-income country settings, and underscores its potential to increase immunization coverage and timeliness by eliminating MOVs.

Gambaran Persepsi Ibu Terhadap Kunjungan Imunisasi Dasar pada Masa Pandemi Covid-19 di Wilayah Kerja Puskesmas Naioni

During the COVID-19 pandemic, there was a decrease in basic immunization visits during the pre-pandemic and post-pandemic periods. IDL coverage decreased from 68,9% in 2019 to 60,8% in 2021, while HB-0 basic immunization visits decreased from 39,7% to 10,4%.Immunizations must still be carried out even during the COVID-19 pandemic. The purpose of the research is to describe mother's perception of basic immunization visits during the COVID-19 pandemic in the working area of Naioni Health Center, Kupang City. Type of this research is descriptive quantitative with a Cross Sectional research design. The population of this research are the mothers who had babies aged 0-11 months and live in the working area of the Naioni Health Center in December 2021 with totals 267 people. The sampling technique used is simple random sampling with a sample size of 73 people. Data analysis used univariate analysis. The results showed that mothers with a high perceived suspectibility is more visit (87,0%), mothers with a high perceived severity is more visit (65,2%), mothers with a high perceived benefits is more visit (78,3%), mothers with a high perceived barriers is more visit (87,0%), mothers with a high self-efficacy is more visit (95,7%) and mothers with a high cues to action is more visit (52,2%) during the COVID-19 pandemic. Therefore, Health Center plays a role to increase mothers perception and basic immunization visits according to the type and time of administration.

Screening for Hearing Impairment in High-Risk Neonates in a Rural Tertiary Care Center

Introduction: Among the many congenital problems, loss of hearing is one of the most common treatable diseases. Hearing loss in early life can have deleterious effects on the child's psychosocial, scholastic, and social-emotional development. Aims: The aim of this study was to estimate the incidence of neonatal hearing loss in high-risk neonates admitted in a rural tertiary care center. To determine the risk factors predictive of hearing impairment in these neonates. Materials and Methods: About 200 high-risk neonates were included in the study. The first screening by otoacoustic emission (OAE) was conducted before the neonate's discharge from the hospital. If it failed, OAE was repeated after 4 weeks or at the first immunization visit. If it again failed, then Brainstem Evoked Response Audiometry (BERA) was conducted within no more than 3 months. Statistical Analysis Used: It was performed using IBM SPSS Statistics (IBM SPSS Version 28.0. Armonk, NY). The Chi-square test was used to calculate the P value. P &lt; 0.05 was considered statistically significant. Results: In the initial screening, 49 out of 200 high-risk neonates had referred OAE. Out of 49, 20 failed in repeat OAE. Out of these 20 neonates, hearing loss was confirmed in 15 neonates (7.5%) by BERA. The risk factors most commonly associated with hearing loss in the present study were neonatal intensive care unit admission &gt;24 h (7%), hyperbilirubinemia (3%), meningitis (3%), and ototoxic drugs (3%). In the neonates who had hearing loss (15), 93.33% were having more than one risk factor. Conclusions: Our study concludes that there is significant hearing impairment in high-risk neonates. Screening for hearing loss and early identification is needed to modulate the period of neural plasticity, preventing them to banish into a world of social isolation, and educational malaise. The health-care facilities in rural regions have limited settings. Hence, at least a targeted screening is recommended for early detection of hearing loss and rehabilitation.

573. AIMS-trained Residents Exhibit Specific Communication Skills During Virtual Encounters with Standardized Vaccine-Hesitant Parents Following an Online Training Program

Abstract Background There are no accepted best practices for counseling vaccine-hesitant parents, and training in this area is not required in residency. In a prior study (J Pediatr 2022;241:203-11), we demonstrated that in-person training in a structured communication strategy called AIMS (Announce, Inquire, Mirror, Secure) resulted in behaviors of interest during live encounters with standardized patients (SPs) portraying vaccine-hesitant parents. We investigated whether similar effects would be seen if training and SP encounters occurred in a virtual environment. Methods Pediatrics and Medicine-Pediatrics residents were randomized to receive either AIMS or control training. Subjects underwent pre- and post-training SP encounters simulating an immunization visit for a 4-month-old. SP case materials were modified to more closely approximate well-intentioned reluctance to vaccinate and allow for more authentic interaction. Encounters were video-recorded and assessed by 3 raters using the Vaccine Hesitancy Communication Assessment (VHCA), developed and characterized in the initial study but modified based on factor analysis to improve reliability and validity. Subject confidence and SP evaluations of the encounter were assessed pre- and post-training. Investigators, subjects, SPs, and video raters were blinded to treatment allocation. Results Fifty-three subjects completed the protocol and 47 had complete video files. Subject confidence improved in both groups (Panel A). No differences in SP evaluations were detected between groups (B). Preliminary analysis demonstrated that AIMS behaviors were more commonly detected among AIMS-trained subjects than control, as evidenced by an increase in VHCA score (C). Conclusion Communication training and assessment using SPs were both successfully transitioned to a virtual environment; this opens the possibility of efficient training and assessment of residents who are not located on site. Training increased confidence non-specifically. Encounters with SPs can serve as a model to detect learned vaccine-specific communication behaviors among resident providers, but post-encounter assessments by SPs remained insensitive to differences in those behaviors despite modification of the case materials.

Prevention of mother-to-child transmission of HIV at the second immunization visit: a cross-sectional study, Burkina Faso.

To evaluate the performance of the cascade of activities for prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) at the second immunization visit in Burkina Faso. In a cross-sectional study, we recruited mothers attending the second immunization visit for their infant in 20 health centres of Bobo-Dioulasso city, Burkina Faso over 12 months (2019-2020). We administered a short questionnaire to 14 176 mothers and performed HIV serological tests on mothers who had not been tested in the last 3 months. All mothers were asked about their attendance for antenatal care and HIV rapid testing. HIV-infected mothers were also asked about the timing of their HIV diagnosis, antiretroviral therapy, pre-exposure prophylaxis initiation at birth and infant diagnosis of HIV. Of 14 136 respondents, 13 738 (97.2%) had at least one HIV serological test in their lifetime. Of 13 078 mothers who were never tested or were HIV-negative, 12 454 (95.2%) were tested during or after their last pregnancy. Among HIV-infected mothers already aware of their status, 110/111 (99.1%) women were on antiretroviral therapy. Among HIV-exposed infants, 84/101 (83.2%) babies received 6weeks of antiretroviral prophylaxis at birth and 58/110 (52.7%) had a blood sample collected for early infant diagnosis. Only two mothers received their child's test results at the time of the second immunization visit. Four mothers were newly diagnosed as HIV-positive during the study. Collecting data at the second immunization visit, a visit rarely missed by mothers, could be useful for identifying gaps in the PMTCT cascade in settings where mothers are difficult to reach, such as in low-income countries with intermediate or low HIV prevalence.

Diagnosis, Treatment and Prevention of Nutritional Anemia in Children: Recommendations of the Joint Committee of Pediatric Hematology-Oncology Chapter and Pediatric and Adolescent Nutrition Society of the Indian Academy of Pediatrics

Anemia in children is a significant public health problem in our country. Comprehensive National Nutrition Survey 2016-18 provides evidence that more than 50% of childhood anemia is due to an underlying nutritional deficiency. The National Family Health Survey-5 has reported an increase in the prevalence of anemia in the under-five age group from 59% to 67.1% over the last 5 years. Clearly, the existing public health programs to decrease the prevalence of anemia have not shown the desired results. Hence, there is a need to develop nationally acceptable guidelines for the diagnosis, treatment and prevention of nutritional anemia. To review the available literature and collate evidence-based observations to formulate guidelines for diagnosis, treatment and prevention of nutritional anemia in children. These guidelines have been developed by the experts from the Pediatric Hematology-Oncology Chapter and the Pediatric and Adolescent Nutrition (PAN) Society of the Indian Academy of Pediatrics (IAP). Key areas were identified as: epidemiology, nomenclature and definitions, etiology and diagnosis of iron deficiency anemia (IDA), treatment of IDA, etiology and diagnosis of vitamin B12 and/or folic acid deficiency, treatment of vitamin B12 and/or folic acid deficiency anemia and prevention of nutritional anemia. Each of these key areas were reviewed by at least 2 to 3 experts. Four virtual meetings were held in November, 2021 and all the key issues were deliberated upon. Based on review and inputs received during meetings, draft recommendations were prepared. After this, a writing group was constituted which prepared the draft guidelines. The draft was circulated and approved by all the expert group members. We recommend use of World Health Organization (WHO) cut-off hemoglobin levels to define anemia in children and adolescents. Most cases suspected to have IDA can be started on treatment based on a compatible history, physical examination and hemogram report. Serum ferritin assay is recommended for the confirmation of the diagnosis of IDA. Most cases of IDA can be managed with oral iron therapy using 2-3 mg/kg elemental iron daily. The presence of macro-ovalocytes and hypersegmented neutrophils, along with an elevated mean corpuscular volume (MCV), should raise the suspicion of underlying vitamin B12 (cobalamin) or folic acid deficiency. Estimation of serum vitamin B12 and folate level are advisable in children with macrocytic anemia prior to starting treatment. When serum vitamin B12 and folate levels are unavailable, patients should be treated using both drugs. Vitamin B12 should preferably be started 10-14 days ahead of oral folic acid to avoid precipitating neurological symptoms. Children with macrocytic anemia in whom a quick response to treatment is required, such as those with pancytopenia, severe anemia, developmental delay and infantile tremor syndrome, should be managed using parenteral vitamin B12. Children with vitamin B12 deficiency having mild or moderate anemia may be managed using oral vitamin B12 preparations. After completing therapy for nutritional anemia, all infants and children should be advised to continue prophylactic iron-folic acid (IFA) supplementation as prescribed under Anemia Mukt Bharat guidelines. For prevention of anemia, in addition to age-appropriate IFA prophylaxis, routine screening of infants for anemia at 9 months during immunization visit is recommended.

Influence of family planning and immunization services integration on contraceptive use and family planning information and knowledge among clients: A cross-sectional analysis in urban Nigeria.

Reproductive autonomy necessitates that women have access to high quality family planning information and services. Additionally, closely spaced pregnancies increase maternal and infant morbidity and mortality. Although integrating family planning into child immunization services may increase access to information and services and postpartum contraceptive use, evidence on how integration affects service delivery and health outcomes is scarce. One limitation of previous studies is the use of binary integration measures. To address this limitation, this study applied Provider and Facility Integration Index scores to estimate associations between integration and contraceptive use, receipt of family planning information, and knowledge of family planning services availability. This study leveraged pooled cross-sectional health facility client exit interview data collected from 2,535 women in Nigeria. Provider and Facility Integration Index scores were calculated (0–10, 0 = low, 10 = high) for each facility (N = 94). The Provider Integration Index score measures provider skills and practices that support integrated service delivery; the Facility Integration Index score measures facility norms that support integrated service delivery. Logistic regression models identified associations between Provider and Facility Integration Index scores and (a) contraceptive use among postpartum women, (b) receipt of family planning information during immunization visits, and (c) correct identification of family planning service availability. Overall, 46% of women were using any method of contraception, 51% received family planning information during the immunization appointment, and 83% correctly identified family planning service availability at the facility. Mean Provider and Facility Integration Index scores were 6.46 (SD = 0.21) and 7.27 (SD = 0.18), respectively. Provider and Facility Integration Index scores were not significantly associated with postpartum contraceptive use. Facility Integration Index scores were negatively associated with receipt of family planning information. Provider Integration Index scores were positively associated with correct identification of family planning service availability. Our results challenge the position that integration provides a clear path to improved outcomes. The presence of facility and provider attributes that support integration may not result in the delivery of integrated care.

Chest HRCT Assessment of COVID-19 Patients in Vaccinated versus Nonvaccinated Patients: A Comparative Study in a Tertiary Care Hospital.

Coronavirus disease 2019 (COVID-19) has turned out to be the most devastating viral disease that the world has encountered for the past century. The World Health Organization (WHO) declared it a pandemic on March 11, 2020. The disease mainly spreads through respiratory droplets which makes social distancing a primary tool of prevention. Many variant strains have emerged up since the pandemic started and the Delta variant is responsible for recent surge of cases in second wave of COVID-19 in India. Mass vaccination is the most efficacious precautionary measure that can be applied to stop the transmission and generate herd immunity. Vaccination does not give 100% prevention from infection, but it halts the severity of infection. Vaccine is the boon amidst the mayhem. Our study highlights that those vaccinated (particularly two doses) had clinically mild symptoms and mild computed tomography severity score (CTSS) with a speedy recovery. Those unvaccinated had moderate to severe symptoms with moderate to severe CTSS (>8) often requiring hospital admission and having poor prognosis. Thus, vaccine helps reduce the health burden of the already strained health care system. Immunization visit can also be used as an opportunity to disseminate message to encourage behavior, to reduce transmission risk of COVID-19 virus, to identify the signs and symptoms of disease, and to provide guidance on what to do.

Association Between Earlier Introduction of Peanut and Prevalence of Peanut Allergy in Infants in Australia

Randomized clinical trials showed that earlier peanut introduction can prevent peanut allergy in select high-risk populations. This led to changes in infant feeding guidelines in 2016 to recommend early peanut introduction for all infants to reduce the risk of peanut allergy. To measure the change in population prevalence of peanut allergy in infants after the introduction of these new guidelines and evaluate the association between early peanut introduction and peanut allergy. Two population-based cross-sectional samples of infants aged 12 months were recruited 10 years apart using the same sampling frame and methods to allow comparison of changes over time. Infants were recruited from immunization centers around Melbourne, Australia. Infants attending their 12-month immunization visit were eligible to participate (eligible age range, 11-15 months), regardless of history of peanut exposure or allergy history. Questionnaires collected data on demographics, food allergy risk factors, peanut introduction, and reactions. All infants underwent skin prick tests to peanut and those with positive results underwent oral food challenges. Prevalence estimates were standardized to account for changes in population demographics over time. This study included 7209 infants (1933 in 2018-2019 and 5276 in 2007-2011). Of the participants in the older vs more recent cohort, 51.8% vs 50.8% were male; median (IQR) ages were 12.5 (12.2-13.0) months vs 12.4 (12.2-12.9) months. There was an increase in infants of East Asian ancestry over time (16.5% in 2018-2019 vs 10.5% in 2007-2011), which is a food allergy risk factor. After standardizing for infant ancestry and other demographics changes, peanut allergy prevalence was 2.6% (95% CI, 1.8%-3.4%) in 2018-2019, compared with 3.1% in 2007-2011 (difference, -0.5% [95% CI, -1.4% to 0.4%]; P = .26). Earlier age of peanut introduction was significantly associated with a lower risk of peanut allergy among infants of Australian ancestry in 2018-2019 (age 12 months compared with age 6 months or younger: adjusted odds ratio, 0.08 [05% CI, 0.02-0.36]; age 12 months compared with 7 to less than 10 months: adjusted odds ratio, 0.09 [95% CI, 0.02-0.53]), but not significant among infants of East Asian ancestry (P for interaction = .002). In cross-sectional analyses, introduction of a guideline recommending early peanut introduction in Australia was not associated with a statistically significant lower or higher prevalence of peanut allergy across the population.
