The purpose of this study was to examine the effect of tooth loss on blood pressure among Congolese population. Methods: A cross-sectional study was conducted from October 2019 until December 2023 among Congolese population aged at least 30 years reporting to the living in DR Congo. All participants were enrolled from Dental Clinic located in the DR Congo. To be eligible to participate in the study, were the willing to participate and having signed informed consent;had a missing tooth;had carried out blood pressure measurement (hypertension/normotensive). The exclusion criteria were determined: being less than 30 years old, being pregnant for women considering the risk of existing gestational hypertension, obesity, excessive alcohol consumption, smoking, and diabetes. Hypertension was defined as the mean of three measurements of systolic blood pressure (SBP) (140 mmHg or higher), diastolic blood pressure (DBP) (90 mm or higher) or physician diagnosed hypertension confirmed from medical records. We determined the number of tooth loss from oral examination. A multivariable logistic regression model was used to investigate the effect of tooth loss on blood pressure. Results: In all, 25,396 participants were enrolled among Congolese population for this study. After oral examination, 13,421 were excluded for no tooth loss and 11,975 participants were selected. The average number of tooth loss among study population was 11.06. Among the participants with hypertension had lost an average of 11 teeth, significantly higher than those without hypertension (6.09) (p = 0.001). After adjusting for covariates (socio-demographic characteristics), tooth loss (>10) was significantly associated with hypertension, with OR = 1.32 (95% CI 1.073 - 2.38). Conclusion: Tooth loss maybe associated with severe hypertension among Congolese population adults. Prevention of tooth loss is very important to the overall health of this population.展开更多

This study aimed to assess the prevalence of these conditions in the urban commune of Dubréka, in Guinea, and to assess the role of demographic and cultural factors in their incidence and management. A cross-sectional study was conducted with 287 participants (174 women and 113 men) in Dubréka. Data were summer collected on the characteristics of sociodemographics, BMI, blood pressure and fasting blood glucose. The prevalence of hypertension and diabetes was determined, and participants’ knowledge and treatment practices were assessed in the summer. The prevalence of hypertension in the study population was 73.52%, affecting both sexes, with women presenting a higher prevalence. The prevalence of diabetes is slightly higher (75.29%) than that of men (70.79%) was 36.59%, with men (38.05%) being slightly more affected than women (35.63%). Obesity and overweight were contributory important factors, affecting respectively 25.78% and 37.28% of the population. Among the hypertensive people, 84.83% were aware of their condition, but only 7.26% received treatment, with no case-controlled hypertension having no summer observed. Socio-economic factors, including the urban setting and proximity to the capital, have probably contributed to these results. The high prevalence of hypertension and diabetes in Dubréka reflects the broader epidemiological transition in sub-Saharan Africa, with women being disproportionately affected by hypertension linked to obesity. Access limited to health care, especially in terms of treatment and care, further aggravates the burden of these diseases. Public health interventions are urgently needed to improve awareness, treatment accessibility and culturally appropriate management strategies adapted to fight against the growing burden of NCDs in Guinea peri-urban.展开更多

This study compares the performance of Holt-Winters’ Exponential Smoothing, Harmonic, and Artificial Neural Network (ANN) models using data from January 2018 to December 2023, incorporating both historical case records from Sierra Leone’s Health Management Information System (HMIS) and meteorological variables including humidity, precipitation, and temperature. The ANN model demonstrated superior performance, achieving a Mean Absolute Percentage Error (MAPE) of 4.74% before including climatic variables. This was further reduced to 3.9% with the inclusion of climatic variables, outperforming traditional models like Holt-Winters and Harmonic, which yielded MAPEs of 22.53% and 17.90% respectively. The ANN’s success is attributed to its ability to capture complex, non-linear relationships in the data, particularly when enhanced with relevant climatic variables. Using the optimized ANN model, we forecasted malaria cases for the next 24 months, predicting a steady increase from January 2024 to December 2025, with seasonal peaks. This study underscores the potential of machine learning approaches, particularly ANNs, in epidemiological modelling and highlights the importance of integrating environmental factors into malaria prediction models, recommending the ANN model for informing more targeted and efficient malaria control strategies to improve public health outcomes in Sierra Leone and similar settings.展开更多

Methods: A retrospective analysis was conducted on the HPV test results from January 1, 2024, to November 30, 2024, at Beiliu Maternal and Child Health Hospital. We statistically analyzed the positive rates of different HPV genotypes and the co-infection status of multiple genotypes. Results: A total of 7558 individuals were tested, with 1103 positive cases identified, resulting in a positivity rate of 14.59%. Among these, HPV type 52 had the highest positive rate, accounting for 18.47%. The co-infection analysis showed that there were 788 cases with single genotype positivity, 236 with double genotype positivity, and 58 with triple genotype positivity, while cases with multiple genotypes simultaneously positive were relatively rare. Conclusion: The HPV infection rate among women of appropriate age in Beiliu City is relatively high, especially for high-risk HPV types. To reduce the future incidence of cervical cancer, it is recommended to enhance health education and vaccination efforts for this population.展开更多

These gaps required innovative problem-solving by public health agencies (PHAs), including local health departments (LHDs), to respond to rapidly changing community conditions during and after the pandemic. Many schools and programs of public health (SPPH) worked with PHAs to mobilize public health (PH) students through practice-based teaching (PBT). Current research indicates PBT benefits all stakeholders—PHAs, students, faculty, SPPH, and ultimately the community served. However, more research is needed on the utility of PBT in addressing a community’s systemic public health issues, the extent to which the academic-community collaboration enhances a PHA’s capacity, and the impact of the pedagogy on preparing the workforce for an evolving PH landscape. This paper examines the process of a semester-long PBT course, guided by the PBT STEPS framework, which includes five steps from collaboration to implementation to evaluation of a PBT course. The collaborating PHA and its student group addressed community trauma and resilience issues during the semester. Additionally, it examines the longer-term impacts after the semester for the PHA, community, and the workforce by 1) conducting a formative evaluation to understand needs and gaps in the community;2) redesigning an intervention that merged the results of the formative evaluation with the intervention developed during the semester;and 3) securing funding and resources for intervention sustainability. Through the documentation of a post-course partnership between an LHD and faculty at a large school of public health, this case study illustrates the potential for PBT to lay the foundation for ongoing research that supports more impactful interventions for PHAs while bolstering the workforce abilities of students as future practitioners.展开更多

文摘Background: Tooth loss results in impaired mastication, which in turn, makes it difficult to chew hard food, consequently leading to deteriorate dietary habits and to develop hypertension. The purpose of this study was to examine the effect of tooth loss on blood pressure among Congolese population. Methods: A cross-sectional study was conducted from October 2019 until December 2023 among Congolese population aged at least 30 years reporting to the living in DR Congo. All participants were enrolled from Dental Clinic located in the DR Congo. To be eligible to participate in the study, were the willing to participate and having signed informed consent;had a missing tooth;had carried out blood pressure measurement (hypertension/normotensive). The exclusion criteria were determined: being less than 30 years old, being pregnant for women considering the risk of existing gestational hypertension, obesity, excessive alcohol consumption, smoking, and diabetes. Hypertension was defined as the mean of three measurements of systolic blood pressure (SBP) (140 mmHg or higher), diastolic blood pressure (DBP) (90 mm or higher) or physician diagnosed hypertension confirmed from medical records. We determined the number of tooth loss from oral examination. A multivariable logistic regression model was used to investigate the effect of tooth loss on blood pressure. Results: In all, 25,396 participants were enrolled among Congolese population for this study. After oral examination, 13,421 were excluded for no tooth loss and 11,975 participants were selected. The average number of tooth loss among study population was 11.06. Among the participants with hypertension had lost an average of 11 teeth, significantly higher than those without hypertension (6.09) (p = 0.001). After adjusting for covariates (socio-demographic characteristics), tooth loss (>10) was significantly associated with hypertension, with OR = 1.32 (95% CI 1.073 - 2.38). Conclusion: Tooth loss maybe associated with severe hypertension among Congolese population adults. Prevention of tooth loss is very important to the overall health of this population.
文摘Hypertension high blood pressure (HTN) and diabetes Type 2 diabetes mellitus (T2DM) are noncommunicable diseases (NCDs) growing in sub-Saharan Africa, under the effect of urbanization, changes in socio-economic and lifestyle-related factors. This study aimed to assess the prevalence of these conditions in the urban commune of Dubréka, in Guinea, and to assess the role of demographic and cultural factors in their incidence and management. A cross-sectional study was conducted with 287 participants (174 women and 113 men) in Dubréka. Data were summer collected on the characteristics of sociodemographics, BMI, blood pressure and fasting blood glucose. The prevalence of hypertension and diabetes was determined, and participants’ knowledge and treatment practices were assessed in the summer. The prevalence of hypertension in the study population was 73.52%, affecting both sexes, with women presenting a higher prevalence. The prevalence of diabetes is slightly higher (75.29%) than that of men (70.79%) was 36.59%, with men (38.05%) being slightly more affected than women (35.63%). Obesity and overweight were contributory important factors, affecting respectively 25.78% and 37.28% of the population. Among the hypertensive people, 84.83% were aware of their condition, but only 7.26% received treatment, with no case-controlled hypertension having no summer observed. Socio-economic factors, including the urban setting and proximity to the capital, have probably contributed to these results. The high prevalence of hypertension and diabetes in Dubréka reflects the broader epidemiological transition in sub-Saharan Africa, with women being disproportionately affected by hypertension linked to obesity. Access limited to health care, especially in terms of treatment and care, further aggravates the burden of these diseases. Public health interventions are urgently needed to improve awareness, treatment accessibility and culturally appropriate management strategies adapted to fight against the growing burden of NCDs in Guinea peri-urban.
文摘Malaria remains a major public health challenge necessitating accurate predictive models to inform effective intervention strategies in Sierra Leone. This study compares the performance of Holt-Winters’ Exponential Smoothing, Harmonic, and Artificial Neural Network (ANN) models using data from January 2018 to December 2023, incorporating both historical case records from Sierra Leone’s Health Management Information System (HMIS) and meteorological variables including humidity, precipitation, and temperature. The ANN model demonstrated superior performance, achieving a Mean Absolute Percentage Error (MAPE) of 4.74% before including climatic variables. This was further reduced to 3.9% with the inclusion of climatic variables, outperforming traditional models like Holt-Winters and Harmonic, which yielded MAPEs of 22.53% and 17.90% respectively. The ANN’s success is attributed to its ability to capture complex, non-linear relationships in the data, particularly when enhanced with relevant climatic variables. Using the optimized ANN model, we forecasted malaria cases for the next 24 months, predicting a steady increase from January 2024 to December 2025, with seasonal peaks. This study underscores the potential of machine learning approaches, particularly ANNs, in epidemiological modelling and highlights the importance of integrating environmental factors into malaria prediction models, recommending the ANN model for informing more targeted and efficient malaria control strategies to improve public health outcomes in Sierra Leone and similar settings.

文摘The pandemic highlighted significant gaps in the public health infrastructure impacted by shortages of public health workers, an undertrained workforce, and years of disinvestment. These gaps required innovative problem-solving by public health agencies (PHAs), including local health departments (LHDs), to respond to rapidly changing community conditions during and after the pandemic. Many schools and programs of public health (SPPH) worked with PHAs to mobilize public health (PH) students through practice-based teaching (PBT). Current research indicates PBT benefits all stakeholders—PHAs, students, faculty, SPPH, and ultimately the community served. However, more research is needed on the utility of PBT in addressing a community’s systemic public health issues, the extent to which the academic-community collaboration enhances a PHA’s capacity, and the impact of the pedagogy on preparing the workforce for an evolving PH landscape. This paper examines the process of a semester-long PBT course, guided by the PBT STEPS framework, which includes five steps from collaboration to implementation to evaluation of a PBT course. The collaborating PHA and its student group addressed community trauma and resilience issues during the semester. Additionally, it examines the longer-term impacts after the semester for the PHA, community, and the workforce by 1) conducting a formative evaluation to understand needs and gaps in the community;2) redesigning an intervention that merged the results of the formative evaluation with the intervention developed during the semester;and 3) securing funding and resources for intervention sustainability. Through the documentation of a post-course partnership between an LHD and faculty at a large school of public health, this case study illustrates the potential for PBT to lay the foundation for ongoing research that supports more impactful interventions for PHAs while bolstering the workforce abilities of students as future practitioners.
