Implementation research on registering cancer cases in primary health centres of Puducherry through community health workers.

Background & objectives Hospital-based cancer registry does not represent the true burden of cancer in the community. Initiating a Primary Health Centre (PHC)-based cancer registry may better estimate population-level data for cancer cases in an area. This study aimed to set up a system for facilitating a PHC-based cancer registry and to assess the registration status of cancer cases in various PHCs of Puducherry. The facilitating and limiting factors while setting up this registry were also assessed. Methods A quasi-experimental study with an embedded mixed-method design was conducted in 31 PHCs/Community Health Centres (CHCs) from March 2021 to November 2022. The interventions were implemented in all PHCs/CHCs of Puducherry with the involvement of the State Non-Communicable Diseases (NCD) cell. The line list of cancer cases from the Jawaharlal Institute of Postgraduate Medical Education & Research (JIPMER) Hospital-based cancer registry was shared with all PHCs/CHCs. Sensitization sessions for all Community Health Workers (CHWs) were conducted, and feedback on cancer registration status was given to the State NCD cell. Focus group discussion (FGD)/Key informant interview (KII) was undertaken to understand strengths, challenges, and suggestions. The logic model was used to understand the various indicators while setting up this PHC-based cancer registry. Results Over a one-year intervention period, 1270 cancer cases were registered at Puducherry's PHCs/CHCs, 1203 (88%) from the shared list and 67(5%) from other facilities. However, only 53 per cent of the expected living cases were captured in the various PHCs. Major limitations for registration were the COVID-19 pandemic, stigma, inadequate manpower, infrastructure issues, and privacy concerns during screening. Interpretation & conclusions It was feasible to set up a PHC-based cancer registry in all PHCs of Puducherry. However, registration of cancer cases was suboptimal, as population-based screening of cancer cases, as recommended in the National Programme for Prevention & Control of Non-Communicable Diseases (NP-NCD) programme, was weak due to the COVID-19 pandemic. Once this is strengthened, the PHC-based cancer registry will better represent the population.

Performance of health and wellness centre in providing primary care services in Chhattisgarh, India.

INTRODUCTION: Primary health care has regained its importance in global policy making. In 2018, the Government of India initiated the Ayushman Bharat - Comprehensive Primary Health Care (AB-CPHC) programme. It was based on upgrading the existing primary health facilities into Health and Wellness Centers (HWCs). The current study aimed to assess the readiness and performance of HWCs in providing comprehensive primary health care services in India's Chhattisgarh state. METHODS: We conducted a cross-sectional health facility assessment with a state-representative sample of 404 HWCs. A standardized health facility survey tool was used to collect information on essential inputs and service outputs of HWCs. The expected population healthcare needs were estimated using secondary sources. The performance of HWCs was assessed by comparing the volume of services provided against the expected population need for outpatient care. RESULTS: On an average, 358 outpatients including 128 non-communicable disease (NCD) patients were treated monthly at an HWC. HWCs were able to cover 31% of the total population's health need for outpatient care, 26% for hypertension, and 21% for diabetes care. In addition to services for reproductive and child health, HWCs provided services for common acute ailments (cold, cough, fever, aches and pains); infections of skin, eye, ear, and reproductive tract, and minor injuries. HWCs were also contributing significantly to national disease control programmes. Acute ailments followed by NCDs and communicable diseases had the largest share among services provided. The key gaps were in coverage of mental illnesses and chronic respiratory diseases. Most of the HWCs showed adequate readiness for the availability of required human resources, supplies, and infrastructure. CONCLUSION: HWCs were able to provide a comprehensive range of primary care services and able to cater to a sizable portion of the rural population's acute and chronic health care needs. The performance was made possible by the adequate availability of medicines, staff, training programmes and tele-consultation linkages. If HWCs in other states are able to reach a similar level of performance, the initiative will prove to be a game changer for equitable primary care in India.

A low-cost approach to upskilling tutors in frontline health care worker production value chain.

Nigeria, like many countries, struggles with a shortage of healthcare professionals including frontline healthcare providers at the primary healthcare (PHC) level. While the country is pitched towards producing more healthcare professionals, the existing infrastructure to produce them is inadequate. Producing healthcare professional with the required skills to deliver quality services is impeded by several factors including the use of outdated curricula for their training, low application of technology in teaching, and weak tutor capacity that is worsened by the paucity and high cost of opportunities for tutor continuing professional development. To address these issues, the Health Workforce Management Activity (HWM), an initiative of the United States Agency for International Development (USAID), in 2023 designed and implemented a low-cost programme called TutorConnect that offered low-cost continuing professional development to tutors. TutorConnect is a Zoom-based monthly training programme that is facilitated by subject matter experts. The programme offered topics spanning effective learning, enhanced instructional design, and improved student engagement in the 14 months of its operation with over 700 tutors from more than 10 states in Nigeria that benefited from it. Utilising WhatsApp for additional support and peer-to-peer learning was crucial to providing more hands-on support, and institution-specific solutions. This low-cost approach to build competencies enabled access to continuing professional development by tutors, limiting effects of location and finances as barriers to continuing professional development. Developing the teaching capacity of tutors is pivotal to enhancing the quality of frontline healthcare worker training.

Clinical Efficacy and Safety of transarterial chemoembolization Combined with Targeted Therapy for primary hepatocellular carcinoma.

Objective: To explore the clinical efficacy and safety of transarterial chemoembolization (TACE) combined with targeted therapy for primary hepatocellular carcinoma (PHC). Methods: This was a retrospective study. Retrospective selection of 150 PHC patients admitted to the Renmin Hospital, Hubei University of Medicine January 2019 and June 2021 were included. The patients were divided into the control group and the experimental group according to their treatment regimens. The control group received TACE treatment, while the experimental group received TACE combined with targeted therapy. We analyze the relevant data of two groups of patients and evaluate the clinical efficacy and safety of TACE combined with targeted therapy. Results: The tumor remission rate and control rate in the control group were 41.89% and 75.68%, respectively, while those in the experimental group were 77.63% and 90.79%, with statistically significant differences (p<0.05). The 1-year and 3-year recurrence rates in the control group were 52.71% and 98.65%, respectively, while those in the experimental group were 39.47% and 61.84%, with statistically significant differences (p<0.05). After treatment, the AFP, VEGF, ALT, and AST in the experimental group were significantly reduced compared to the control group (p<0.05). During the treatment period, the incidence and severity of nausea, vomiting, and fever in the experimental group were significantly lower than those in the control group (p<0.05). Conclusion: The clinical efficacy of TACE combined with targeted therapy for PHC is superior to that of TACE alone, with improved disease control rate, improved long-term survival rate, and good safety.

Knowledge, attitudes, and barriers: Palliative Care services for women with HIV in resource-limited settings.

BACKGROUND: Women living with HIV (WLWH) in low- middle-income countries (LMICs) face increased mortality risks from comorbidities despite progress in antiretroviral therapy. Palliative care (PC) is vital for these patients, yet its integration in LMICs, such as Nigeria, is suboptimal due to unique challenges. OBJECTIVE: This study investigated the knowledge, perceived barriers, and facilitators influencing PC integration into routine HIV care within healthcare (HC) settings. METHODOLOGY: A cross-sectional survey was conducted among WLWH in twelve HC facilities throughout Nigeria. Data collection involved surveys focused on PC knowledge, attitudes, facilitators, and barriers. Logistic regression analyses were employed to examine the data. RESULTS: This study revealed significant gaps in knowledge and attitudes towards PC among HIV + women at NISA-MIRCs. Over 90% were unaware of PC services, but many saw its potential to offer hope (55%) and improve quality of life (56.5%). The key predictors of PC knowledge included education, occupation, religion, having fewer children, urban residence, type of residence, and having a high income (p < .05). Despite the willingness to access PC, barriers such as negative HC worker attitudes, perceived high cost, and limited decision autonomy could hinder integration. Facilitators included low-cost services, positive HCW attitudes, physician recommendations, and perceived necessity for personal well-being. CONCLUSION: Knowledge gaps, diverse attitudes, and significant barriers highlight the need for targeted PC interventions for WLWH. Tailoring educational programs, addressing cost barriers, and improving healthcare infrastructure are crucial to enhancing PC accessibility and quality. These findings can guide policymakers and HC practitioners toward more effective and inclusive care strategies.

Economical Impact of Integration of Mental Health Services to Primary Care - A Review.

There are numerous people all across the world who are struggling with mental health (MH) conditions. There is a growing recognition of the significance of MH as a primary cause of disability with substantial effects on daily functioning. The Ministry of Health's financial division oversees money with the Ministry of Finance's approval. Thus, this review explores the economics of integrating MH services in a primary healthcare center (PHC) in Saudi Arabia (SA). The incorporation of MH services into basic medical care is required as it ensures that the general population has access to the necessary MH care and the likelihood of better health outcomes is raised when receiving treatment in PHCs. The majority of funds that are now allocated to the provision of MH care are used to pay the wages of MH professionals and paramedical staff members who are employed in mental hospitals, as well as to invest in the development of infrastructure and education of MH experts. A report found that MH expenditures accounted for 4% of the entire budget for health care. The expenditure for mental hospitals was 22% of the total for MH hospitals. The allocation of funds is integral for the PHCs to perform at their maximum potential in the MH domain. Thus, this review explores the economics of integrating MH services in a PHC in S SA.

Blood pressure control in Türkiye: A primary healthcare pilot study.

Hypertension is present in almost a third of Türkiye's adult population. The Ministry of Health of the Republic of Türkiye in conjunction with the World Health Organization, rolled out a pilot primary health care model from February 2019 to 2020 to improve hypertension screening, management, and follow-up across the provinces of Erzincan, Çankiri and Usak. The model was conducted in selected family health centers for one year and included multiple interventions - training of multidisciplinary primary care teams, implementation of evidence-based, standardised clinical guidelines related to monitoring and treatment of hypertension, clinical supervision and performance monitoring, and provision of health education to hypertensive individuals. Repeat surveys of population-based random samples of 975 patients were taken before (December 2018) and after (February 2020) model implementation to evaluate its effect on care delivery. There was an almost 6.5-fold increase in the measurement and subsequent recording of blood pressure compared to before model implementation (from 50 to 323). Blood pressure control improved to 58 % of measured individuals compared to 46 % of those measured at initial evaluation. The frequency of measuring risk factors and outcomes related to hypertension at least once a year increased for creatinine from 71 % to 79 %, fasting blood glucose from 70 % to 78 %, and tobacco use from 22 % to 31 %. Prescription of antihypertensive drugs increased from 49 % to 61 %. With improvements in hypertension-related care in all measures and across all regions, this primary healthcare model represents a potential paradigm for nationwide implementation.

Primary health care in Nigeria: best practices and quality of care in Nigeria.

INTRODUCTION: The significance of Primary Healthcare Centers (PHCCs) in fostering health equity and enhancing health outcomes cannot be overstated, especially in low and middle-income countries. This paper's primary area of interest is to create evidence and innovation for PHCs, with a particular emphasis on underserved groups. Thus, the study aimed to investigate the state of primary health care in Nigeria, with a particular emphasis on best practices, challenges to best practices, and quality of care. METHODOLOGY: A cross-sectional quantitative study was conducted to collect secondary data from 29 primary healthcare facilities. The data was collected using staff and facility activity indicators over a year (2022). Descriptive statistics and chi-square tests were used to analyze the collected data. RESULT: Our study data showed that all of the PHCCs have service rosters that can be utilized for follow-up with patients. About 85 (84.1%) respondents have reported that deliveries were taken by the reporting midwife, and 55 (54.5%) respondents indicated that their facilities provided on-the-job training to their staff. This is considered as the best practice in the facility. However, the majority of the PHCCs (71.3%) lacked assessment teams, which was found to have a negative impact on the quality of healthcare provided at these facilities (p < 0.05). CONCLUSION: Our study underscores the pressing need for primary healthcare services in Nigeria. Government authorities and healthcare providers must take action to overcome the challenges of limited capacity, service delivery, and quality of care. By adopting effective strategies and ensuring access to primary healthcare, citizens' health outcomes can be greatly enhanced. Thus, it is essential to revamp and optimize healthcare facilities to establish an efficient healthcare system that caters to the needs of all citizens.

Primary Healthcare Marketing: A Bibliometric Study and Research Agenda.

The evolution of our lives has forced changes to the healthcare system and consequently established healthcare marketing as an essential element of health services, including primary health care (PHC). This article aims to analyze the size, structure, and dynamics of research on primary healthcare marketing to identify the main topics and research trends in this area. The authors conducted a bibliographic analysis based on the methods of performance analysis and scientific mapping. The bibliographical analysis covered 1981 publications selected from the Scopus database and was carried out with the use of the MS Excel and VOSviewer applications. The results were supplemented with an in-depth analysis of 34 publications selected based on bibliographic coupling analysis to determine key research trends and results, which increased the understanding of the research area. The conducted research proves that the issue of marketing in primary health care is rarely addressed by researchers, which translates into very limited research results and little impact on the decision-making process in this area. This research field requires much greater commitment, especially in the areas indicated in the future research agenda recommendations.

Exploring the relationship between vitamin D and hepatic carcinoma in individuals diagnosed with hepatitis B virus infection.

OBJECTIVE: The primary objective of this study is to examine the distribution and prognostic implications of serum vitamin D levels among individuals diagnosed with primary hepatic carcinoma (PHC) attributable to hepatitis B virus (HBV) infection. METHODS: A total of 345 patients diagnosed with HBV infection were enrolled in our hospital between August 2014 and October 2020. Among these, 144 individuals were diagnosed with chronic hepatitis B (CHB), 66 individuals were diagnosed with HBV-related hepatic cirrhosis (HBV cirrhosis), and 135 individuals were diagnosed with HBV-related PHC (HBV-PHC). Peripheral serum levels of vitamin D were measured. Patients with cirrhosis underwent examination using the Child-Pugh grading system, and the mortality rates at 1-year and 3-year intervals for patients with HBV-PHC were analyzed. RESULTS: Vitamin D levels in peripheral serum in the CHB group, HBV cirrhosis group, and HBV-PHC group exhibited varying degrees of reduction compared to healthy individuals. Significant differences were observed between the three groups (F = 4.02, P = 0.019). No significant difference was observed in vitamin D levels between different Child-Pugh grades within the HBV cirrhosis group (F = 0.89, P = 0.417). However, significant differences were observed in vitamin D levels between different Child-Pugh grades within the HBV-PHC group (F = 4.84, P = 0.009). There was no significant difference in 1-year and 3-year mortality rates between patients diagnosed with HBV-PHC and with varying vitamin D levels (P > 0.05). CONCLUSIONS: Vitamin D levels decreased to varying degrees in patients diagnosed with CHB, HBV cirrhosis, and PHC. This decrease was well correlated with disease progression (HBV-PHC group < HBV cirrhosis group < CHB group). In cases where hepatic function was comparable, there was no discernible correlation between serum vitamin D level and mortality rates from PHC.

Kerala's progress towards universal health coverage: the road travelled and beyond.

BACKGROUND: Kerala has initiated many Universal Health Coverage (UHC) reforms in the last decade. The Aardram Mission launched in 2017 stands out owing to its scope, objectives, and commitments for strengthening Primary Health Care (PHC) in the State. The current study proposes to explore access and financial protection through the lens of equity in Kerala especially in the context of major UHC reforms carried out during the last decade. This paper will also highlight the key lessons from Kerala's approach towards UHC and health systems strengthening through a political economy approach. METHODS: Data from the Kerala state sample of 75th Round (2017-18) National Sample Survey is used for this study. Comparison is also drawn from the 71st Round Sample Survey, 2014, to measure the state's progress in terms of access and financial protection. Logistic regression was used for the calculation. The findings were further explored through a political economy approach. RESULTS: The share of public facilities for outpatient care is 47.5%, which is a significant increase from 34.0% (in 2014) in the state. The share of public sector for out-patient care has increased for the lower socio-economic population in the state. The share of public sector for in-patient care has also increased to 37.3% in 2017-18 from 33.9% in 2014, but not to the extent as the increase shown in outpatient care. The average out-of-pocket-expenditure during hospitalization has increased more in private facilities as compared to public for both outpatient care and hospitalization. CONCLUSIONS: Overall increase in the share of public facilities for both outpatient care and hospitalization is indicative of the enhanced trust among the people at large of the public healthcare delivery system in Kerala, post the launch of UHC reforms in the State. The insurance linked UHC reforms would be insufficient for the State to progress further towards UHC. Kerala with a long and successful history in 'public provisioning' should focus more on strengthening PHC through Aardram Mission in its journey towards pursuit of UHC.

Ensemble learning enhances the precision of preliminary detection of primary hepatocellular carcinoma based on serological and demographic indices.

Primary hepatocellular carcinoma (PHC) is associated with high rates of morbidity and malignancy in China and throughout the world. In clinical practice, a combination of ultrasound and alpha-fetoprotein (AFP) measurement is frequently employed for initial screening. However, the accuracy of this approach often falls short of the desired standard. Consequently, this study aimed to investigate the enhancement of precision of preliminary detection of PHC by ensemble learning techniques. To achieve this, 712 patients with PHC and 1887 healthy controls were enrolled for the assessment of four ensemble learning methods, namely, Random Forest (RF), LightGBM, Xgboost, and Catboost. A total of eleven characteristics, comprising nine serological indices and two demographic indices, were selected from the participants for use in detecting PHC. The findings identified an optimal feature subset consisting of eight features, namely AFP, albumin (ALB), alanine aminotransferase (ALT), platelets (PLT), age, alkaline phosphatase (ALP), hemoglobin (Hb), and body mass index (BMI), that achieved the highest classification accuracy of 96.62%. This emphasizes the importance of the collective use of these features in PHC diagnosis. In conclusion, the results provide evidence that the integration of serological and demographic indices together with ensemble learning models, can contribute to the precision of preliminary diagnosis of PHC.

Non-invasive predictors to grade esophageal varices in liver cirrhosis patients.

Background: Portal hypertension commonly occurs due to liver cirrhosis, and esophageal varices (EV) is one of the major complications associated with it. The most common cause of death in liver cirrhosis is EV bleeding. Hence, GE screening for EV is required, which is an invasive procedure. Regular use of endoscopy results in low compliance due to cost and discomfort for patients. Hence, identifying non-invasive markers that could grade EV provides a useful screening tool for family physicians and primary health centers (PHCs) by referring the patient to higher centers for definitive treatment, which could reduce mortality due to variceal bleeding in cirrhotic patients. Aims: To assess non-invasive predictors of grade EV in patients diagnosed with liver cirrhosis. Settings and Design: Cross-sectional study. Methods and Material: A total of 109 patients with liver cirrhosis underwent clinical and biochemical evaluation, USG abdomen with spleen bipolar diameter, ascitic fluid analysis, and upper GE with a grade of EV are recorded. Statistical Analysis Used: SPSS software with Student t-test, Chi-square t-test, analysis of variance, receiver operator characteristic (ROC) curves, and Spearman correlation with 95% CI is used. P <0.05 is considered significant. Results: Aminotransferase to Platelet count Ratio Index (APRI) score >1.815, PC/SD ≤909, and SAAG >1.1g/dl showed EV in liver cirrhosis (P < 0.05). The order of prediction with ROC curves shows APRI score > PC/SD > SAAG. In grading EV, APRI scores of 1.9-2.5 and >2.5 showed small and large EV, respectively (P < 0.05). Conclusions: APRI score may be used in PHC as an early intervention to grade EV and refer the patient to higher centers for definitive treatment. This would prevent the progression of varices to rupture and reduce mortality due to variceal bleeds in liver cirrhosis patients.

Study protocol for a pilot quasi-experimental study on oral health education for nurses and community health workers in Nigeria.

Introduction: The primary health care system provides an ideal setting for the integration of oral health into general health care as well as equitable access to oral health care. However, the limited oral health knowledge of primary health care workers necessitates appropriate training before they can participate in health promotion efforts. This pilot training was designed to examine the impact of the Oral Health Education module for Nurses and Community Health Care Workers on their oral health awareness and referral practices. Methods: This study will utilize a quasi-experimental design (pre-and post with a non-equivalent control group) to assess the impact of a five-day pilot oral health education program on the knowledge and referral practices of Nurses and Community Health Workers in primary health care centers in three states in Nigeria-(Lagos, Oyo, and Kano). The training modules were developed based on the six iterative steps described in the intervention mapping framework - needs assessment, highlighting program objectives and outcomes, selection of theory and mode of intervention, designing program based on theory, designing implementation plans, and developing an evaluation plan. Only the intervention group will participate in the full educational training sessions but both groups will complete the pre-and post-intervention questionnaires. Discussion: This pilot training combined the standardized training modules from the recently launched "Oral Health Training Course for Community Health Workers in Africa" and a newly developed maternal and child oral health module by our group using an evidence-based approach. To the best of our knowledge, this is the first program to examine the impact of the standardized OpenWHO modules. The success of this training will lay the foundation for developing a sustained channel for providing oral health education at the primary health care level in Nigeria, West Africa, and Africa.

Management of iron deficiency anemia during pregnancy: a midwife-led continuity of care model.

Background: Globally, 36.5% of pregnancies are affected by anemia, particularly in low-and middle-income countries, posing significant risks to maternal and perinatal health. In rural Pakistan, 44.3% of pregnant women suffer from iron deficiency, contributing to the high prevalence of anemia. Limited accessibility to antenatal care exacerbates the challenge, necessitating innovative solutions. This study assessed a midwife-led continuity of care model, utilizing intravenous (IV) iron therapy for the management of anemia in Karachi, Pakistan. Methods: We performed a retrospective analysis of data from a prospective cohort study conducted in two primary healthcare facilities, which employed a community midwife (CMW)-led continuity of care model for antenatal care, including IV iron therapy. We extracted data from February 2021 to March 2022 for women who were diagnosed with anemia based on hemoglobin (Hb) levels, categorized as mild (10.0 to 10.9 g/dL), moderate (7.0 to 9.9 g/dL), or severe (less than 7.0 g/dL). Assessment occurred at the initial antenatal care (ANC) visit to establish baseline anemia severity, and approximately 2 weeks after intravenous (IV) iron therapy administration to evaluate post-treatment changes were considered. Results: We enrolled 114 pregnant women, where the majority presented with moderate (88.6%) anemia. After IV iron treatment, 48.5% improved to normal-mild levels, while 50% remained unchanged. Severe anemia affected 10.5% at baseline; 42% shifted to moderate and 50% to normal-mild post-treatment, with one remaining unchanged (p < 0.001). Among women enrolled in the first and second trimesters, severe anemia improved to normal-mild (50%) and moderate levels (50%) (pre-treatment: n = 10, post-treatment: n = 0), and moderate anemia decreased by 48% (pre-treatment: n = 92, post-treatment: n = 47). Conclusion: Our midwife-led model of care demonstrated an improvement in iron levels among pregnant women. The model addressed the challenges of anemia prevalence in Pakistan and underscored the significance of empowering front-line healthcare providers, such as community midwives (CMWs) for managing these common conditions.

Optimizing primary healthcare experience: assessing client satisfaction in Kaduna State, Northwest Nigeria.

BACKGROUND: Client satisfaction is a multidimensional construct focusing on clients' perceptions and evaluations of the treatment and care received. It is one of the factors affecting the outcomes of healthcare and the use of health services. Therefore, we aimed to assess clients' satisfaction with PHC services in Kaduna State, Northwest Nigeria. METHODOLOGY: A cross-sectional descriptive study was conducted in Kaduna State, Northwest, Nigeria which evaluate the satisfaction of clients and caregivers accessing healthcare in PHC centres. A sample size of 217 was determined using Fisher's formula, with a multi-stage sampling technique used to randomly select eligible respondents, who have accessed at least a PHC service in any of the PHCs in the State were included in the study, A semi-structured, interviewer-administered questionnaire was administered, and the data collected was analyzed using SPSS version 23.0. Appropriate statistical tests were used to examine the association between dependent and independent variables, while predictor variables that showed significant association with the outcome variables were further subjected to logistic regression analysis, to determine factors that affect clients' satisfaction with PHC services. Statistical significance was determined at an alpha level set at 0.05 at a 95% confidence interval. RESULTS: Thirty-one percent of the respondents were satisfied with PHC services in Kaduna State with a mean composite satisfaction score of 3.78 ± 0.67. Age, ethnicity, level of education, and occupational status were factors affecting clients' satisfaction with PHC services among the respondents. On multivariate analysis, age, ethnicity, educational status, and occupational status were significant factors affecting clients' satisfaction with PHC services. Clients of Hausa/Fulani extraction are one and a half times less likely to be satisfied with PHC services when compared to clients from other tribes [aOR = 1.5, 95% CI (1.21-4.67); p = 0.003]. In terms of educational status, clients with formal education are one and a one-third times more likely to be satisfied [aOR = 1.3, 95% CI (0.17-0.94)] with PHC service when compared with their counterparts with informal education (p = 0.034). CONCLUSION: Clients' satisfaction with PHC services in Kaduna State, Northwest Nigeria was sub-optimal. Healthcare providers were recommended to improve their attitude bearing in mind clients' peculiarities.

Physical unclonable function using photonic spin Hall effect.

This study presents a novel method leveraging surface wave-assisted photonic spin Hall effect (PSHE) to construct physical unclonable functions (PUFs). PUFs exploit inherent physical variations to generate unique Challenge-Response pairs, which are critical for hardware security and arise from manufacturing discrepancies, device characteristics, or timing deviations. We explore PSHE generation-based PUF design, expanding existing design possibilities. With recent applications in precise sensing and computing, PSHE offers promising performance metrics for our proposed PUFs, including an inter-Hamming distance of 47.50% , an average proportion of unique responses of 62.5% , and a Pearson correlation coefficient of - 0.198. The PUF token demonstrates robustness to simulated noise. Additionally, we evaluate security using a machine learning-based attack model, employing a multi-layer perceptron (MLP) regression model with a randomized search method. The average accuracy of successful attack prediction is 9.70% for the selected dataset. Our novel PUF token exhibits high non-linearity due to the PSHE effect, resilience to MLP-based attacks, and sensitivity to process variation.
