Background

Fear of a global public health issue and fresh infection wave in the persistent COVID-19 pandemic has been enflamed by the appearance of the novel variant Omicron BF.7 lineage. Recently, it has been seeing the novel Omicron subtype BF.7 lineage has sprawled exponentially in Hohhot. More than anything, risk stratification is significant to ascertain patients infected with COVID-19 who the most need in-hospital or in-home management. The study intends to understand the clinical severity and epidemiological characteristics of COVID-19 Omicron subvariant BF.7. lineage via gathering and analyzing the cases with Omicron subvariant in Hohhot, Inner Mongolia.

Methods

Based upon this, we linked variant Omicron BF.7 individual-level information including sex, age, symptom, underlying conditions and vaccination record. Further, we divided the cases into various groups and assessed the severity of patients according to the symptoms of patients with COVID-19. Clinical indicators and data might help to predict disadvantage outcomes and progression among Omicron BF.7 patients.

Results

In this study, in patients with severe symptoms, some indicators from real world data such as white blood cells, AST, ALT and CRE in patients with Omicron BF.7 in severe symptoms were significantly higher than mild and asymptomatic patients, while some indicators were significantly lower.

Conclusions

Above results suggested that the indicators were associated with ponderance of clinical symptoms. Our survey emphasized the value of timely investigations of clinical data obtained by systemic study to acquire detailed information.

Published: February 2024

Background

Tumor mutational burden (TMB) is one of the most significant predictive biomarkers of immunotherapy efficacy in non-small cell lung cancer (NSCLC). Radiomics allows high-throughput extraction and analysis of advanced and quantitative medical imaging features. This study develops and validates a radiomic model for predicting TMB level and the response to immunotherapy based on CT features in NSCLC.

Method

Pre-operative chest CT images of 127 patients with NSCLC were retrospectively studied. The 3D-Slicer software was used to outline the region of interest and extract features from the CT images. Radiomics prediction model was constructed by LASSO and multiple logistic regression in a training dataset. The model was validated by receiver operating characteristic (ROC) curves and calibration curves using external datasets. Decision curve analysis was used to assess the value of the model for clinical application.

Results

A total of 1037 radiomic features were extracted from the CT images of NSCLC patients from TCGA. LASSO regression selected three radiomics features (Flatness, Autocorrelation and Minimum), which were associated with TMB level in NSCLC. A TMB prediction model consisting of 3 radiomic features was constructed by multiple logistic regression. The area under the curve (AUC) value in the TCGA training dataset was 0.816 (95% CI: 0.7109–0.9203) for predicting TMB level in NSCLC. The AUC value in external validation dataset I was 0.775 (95% CI: 0.5528–0.9972) for predicting TMB level in NSCLC, and the AUC value in external validation dataset II was 0.762 (95% CI: 0.5669–0.9569) for predicting the efficacy of immunotherapy in NSCLC.

Conclusion

The model based on CT radiomic features helps to achieve cost effective improvement in TMB classification and precise immunotherapy treatment of NSCLC patients.

Authors: Zhong Mei-ling , Liu Yin-chuan , Yang Jian-tong , Wang Ya-nan , Ao Mei-hong , Xiao Yun , Zeng Si-yuan , Liang Mei-rong
Published: February 2024

Objective

The aim of this study was to compare the therapeutic value and treatment-related complications of radical hysterectomy with those of concurrent chemoradiotherapy (CCRT) for locally resectable (T1a2–T2a1) stage IIIC1r cervical cancer.

Methods

A total of 213 patients with locally resectable stage IIIC1r cervical cancer who had been treated at Jiangxi Maternal and Child Health Care Hospital between January 2013 and December 2021 were included in the study and classified into two groups: surgery (148 patients) and CCRT (65 patients). The disease-free survival (DFS) rate, overall survival (OS) rate, side effects, and economic costs associated with the two groups were compared.

Results

43.9% (65/148) patients in the surgical group had no pelvic lymph node metastasis, and 21of them did not require supplementary treatment after surgery due to a low risk of postoperative pathology. The median follow-up time was 46 months (range: 7–108 months). The five-year DFS and OS rates of the surgery group were slightly higher than those of the CCRT group (80.7% vs. 75.1% and 81.6% vs. 80.6%, respectively; p > 0.05). The incidences of grade III–IV gastrointestinal reactions in the surgery and CCRT groups were 5.5% and 9.2%, respectively (p = 0.332). Grade III–IV myelosuppression was identified in 27.6% of the surgery group and 26.2% of the CCRT group (p = 0.836). The per capita treatment cost was higher for the surgery group than for the CCRT group (RMB 123, 918.6 0 vs. RMB 101, 880.90, p = 0.001).

Conclusion

The therapeutic effects and treatment-related complications of hysterectomy and CCRT are equivalent in patients with locally resectable stage IIIC1r cervical cancer, but surgery can provide accurate lymph node information and benefit patients with unnecessary radiation.

Published: February 2024

Background

The clinical significance of single cell invasion and large nuclear diameter is not well documented in early-stage oral tongue squamous cell carcinoma (OTSCC).

Methods

We used hematoxylin and eosin-stained sections to evaluate the presence of single cell invasion and large nuclei in a multicenter cohort of 311 cases treated for early-stage OTSCC.

Results

Single cell invasion was associated in multivariable analysis with poor disease-specific survival (DSS) with a hazard ratio (HR) of 2.089 (95% CI 1.224–3.566, P = 0.007), as well as with disease-free survival (DFS) with a HR of 1.666 (95% CI 1.080–2.571, P = 0.021). Furthermore, large nuclei were associated with worse DSS (HR 2.070, 95% CI 1.216–3.523, P = 0.007) and with DFS in multivariable analysis (HR 1.645, 95% CI 1.067–2.538, P = 0.024).

Conclusion

Single cell invasion and large nuclei can be utilized for classifying early OTSCC into risk groups.

Authors: Huang Chun-Yao , Hsieh Min-Shiau , Hsieh Po-Chun , Wu Yao-Kuang , Yang Mei-Chen , Huang Shiang-Yu , Tzeng I-Shiang , Lan Chou-Chin
Published: February 2024

Background

Lung cancer significantly impairs exercise capacity and health-related quality of life (HRQL). Pulmonary rehabilitation (PR) has demonstrated positive effects on exercise capacity and HRQL in lung cancer patients. However, its impact on cardiopulmonary function needs further exploration. The aim of this study was to explore the effects of PR on cardiopulmonary function, exercise capacity and HRQL in patients with lung cancer.

Methods

Patients with lung cancer were enrolled in a 12-week PR program. Each participant underwent a thorough evaluation, which included spirometry, cardiopulmonary exercise testing, respiratory muscle strength test, and evaluation of HRQL using the Chronic Obstructive Pulmonary Disease Assessment Test (CAT).

Results

Fifty-six patients completed the PR program. Following PR, exercise capacity significantly improved, as evidenced by increased peak oxygen uptake and work rate (both p < 0.05). Exertional symptoms were notably reduced, including leg soreness and dyspnea at peak exercise, accompanied by a decrease in the CAT score (all p < 0.05). Furthermore, improvements in cardiopulmonary function were observed, encompassing respiratory muscle strength, ventilatory equivalent, tidal volume, stroke volume index, and cardiac index at peak exercise (all p < 0.05).

Conclusions

PR demonstrated notable enhancements in cardiopulmonary function, exertional symptoms, exercise capacity, and HRQL in patients with lung cancer.
Influencing factors comparing different vault groups after phakic implantable collamer lens implantation: review and meta-analysis
Authors: Zhang Pengcheng , Guo Chenjun , Wang Song , Jiang Wenshan , Wang Dan , Yan Hong
Published: February 2024

Background

Studies on the factors affecting vault after posterior chamber phakic Implantable Collamer Lens (ICL) have been carried out, but most of them are single-centered and subjective selections of parameters. The present study aimed to systematically analyze the factors for vault.

Methods

A systematic review of case series, case-control, and cohort studies derived from the articles published in PubMed, the Cochrane Library, Embase, Web of Science, CNKI, CBM, Wanfang and VIP, as well as ClinicalTrials, which were conducted to search for studies on factors of vault using four core terms: phakic intraocular lenses, vault, risk factor and observational study, from January 01, 1997, to February 20, 2023. The included studies were meta-analyzed quantitatively and described qualitatively. Subsequently, meta-regression and subgroup analysis were used.

Results

We identified 13 studies (1,607 subjects), and 14 factors were considered. Meta-analysis showed that anterior chamber depth (ACD), horizontal corneal white-to-white (hWTW), ICL-size, and age are dual effects of the abnormal vaults; anterior chamber volume (ACV) and lens thickness (LT) are a one-way effect; while axial length (AL), ICL- spherical equivalent (ICL-SE) and Km are insignificant. In addition, descriptive analysis of anterior chamber angle (ACA), horizontal sulcus to sulcus (hSTS), ciliary processes height (T value), crystalline lens rise (CLR), and gender showed that all factors except gender tend to have significant effects on vault. Sensitivity analysis showed stable combined results. Country and design respectively affect the heterogeneity in ACD and ICL-size at low vault, while design affects the heterogeneity in ACD at high vault. No publication bias exists.

Conclusions

Vault after ICL is related to multiple factors, especially anterior segmental biologic parameters, and they are weighted differently. We hope to provide a reference for the selection and adjustment of ICL.
Prevalence and predictors of self-reported hearing aid use and benefit in Norway: the HUNT study
Authors: Engdahl Bo , Aarhus Lisa
Published: February 2024

Background

Knowledge on hearing aid use and benefit is important to ensure appropriate and effective treatment. We aimed to assess prevalence and predictors of hearing aid use and benefit in Norway, as well as possible birth cohort changes.

Methods

We analyzed two large cross-sectional, population-based hearing surveys of 63,182 adults in 1996–1998 and 2017–2019 (the HUNT study). We used multivariable regression models to examine independent predictors of hearing aid use and benefit, including demography, hearing-related variables, known risk factors for hearing loss and birth cohort.

Results

The nationally weighted hearing aid use in the adult population increased from 4.2% in 1997 to 5.8% in 2018. The use among individuals with disabling hearing loss (≥ 35 dB HL) increased from 46.3% to 64.4%. Most users reported some (47%) or great (48%) help from their hearing aids. In addition to the level of hearing loss and birth cohort, factors associated with hearing aid use included lower age, tinnitus, childhood-onset hearing loss, higher education, marriage, having children, being exposed to occupational noise or impulse noise, recurrent ear infections, and head injury. In addition to the level of hearing loss, factors related to hearing aid benefit included younger age, female gender, and higher income. Being bothered by tinnitus reduced the benefit.

Conclusion

Our study shows an increase in self-reported hearing aid usage over time in Norway, with lower adoption rates and perceived benefits observed among the elderly. The results suggest that having a spouse and children positively influences the adoption of hearing aids. These findings emphasize the necessity of customized strategies to address demographic disparities and the need for innovative enhancements in hearing rehabilitation programs.
The effect of social support, diabetes management self-efficacy, and diabetes distress on resilience among patients with type 2 diabetes: a moderated mediation analysis
Authors: Parviniannasab Ali Mohammad , Faramarzian Zohreh , Hosseini Seyyed Ali , Hamidizadeh Saeed , Bijani Mostafa
Published: February 2024

Background

Diabetes can result in distress. Improving Resilience is important in managing these conditions. It is also important to consider the mediating role of diabetes management self-efficacy (DMSE) between diabetes distress (DD) and Resilience. Likewise, understanding how social support (SS) buffers the impact of diabetes distress on Resilience is equally important.

Methods

The present study used a cross-sectional design and included 403 participants diagnosed with type 2 diabetes (T2D). The study was conducted in the south of Iran. The participants were selected through convenience sampling from July 2022 to January 2023. Self-reported questionnaires, namely the Diabetes Distress Scale (DDS), Diabetes Management Self-Efficacy Scale (DMSE), Perceived Social Support Scale (PSSS), and Resilience Scale, were used for data collection in the present study. Structural equation modelling was used for moderated mediation analysis.

Results

The results of the Pearson correlation analysis were indicative of a significant negative correlation (p < 0.01) between diabetes distress and diabetes management self-efficacy (r = − 0.607), social support (r = − 0.417), and Resilience (r = − 0.552). The findings further revealed that diabetes management self-efficacy had fully mediated the correlation between diabetes distress and Resilience. Moreover, the results indicated that social support had a moderating role in the DD-resilience link.

Conclusions

The present study’s findings offer a new theoretical framework for T2DM that can benefit intervention designers. The results further suggest that promoting diabetes management self-efficacy can be an effective strategy to enhance Resilience and decrease diabetes distress. Also, nurses and other healthcare providers must pay close attention to support resources to improve the patients’ Resilience and evaluate the distress associated with diabetes.

Authors: Eslami Hosein , Halimi Milani Fatemeh , Salehnia Fatemeh , Kourehpaz Negar , Katebi Katayoun
Published: February 2024

Background

Previous research has investigated the connection between sublingual varices (SV) and cardiovascular disease, aging, and smoking. However, it is still unclear whether arterial hypertension affects the presence of SV. This meta-analysis aimed to investigate the relationship between hypertension and the presence of SV.

Methods

The literature search was performed using PubMed, Web of Science, Scopus, Google Scholar, and Embase for cross-sectional studies until July 2023. PRISMA guidelines were used for article selection. A meta-analysis using standardized mean differences by a random effects model was conducted to pool studies.

Results

A total of 568 articles were retrieved, of which twelve were included in the meta-analysis. Cumulatively, 2543 samples in the case group (1185 with hypertension) and 3897 samples (821 with hypertension) were studied in the control group. Using the random effects model, the pooled odds ratio (OR) revealed a significant association between hypertension and sublingual varices (OR = 2.66; 95% CI: 1.69–4.18).

Conclusion

The meta-analysis showed a significant and positive association between sublingual varices and hypertension. SV’s presence could be used by dentists as a non-invasive indicator of hypertension screening.
Assessing the survival time of women with breast cancer in Northwestern Ethiopia: using the Bayesian approach
Authors: Gashu Chalachew , Aguade Aragaw Eshetie
Published: February 2024

Background

Despite the significant weight of difficulty, Ethiopia's survival rate and mortality predictors have not yet been identified. Finding out what influences outpatient breast cancer patients' survival time was the major goal of this study.

Methods

A retrospective study was conducted on outpatients with breast cancer. In order to accomplish the goal, 382 outpatients with breast cancer were included in the study using information obtained from the medical records of patients registered at the University of Gondar referral hospital in Gondar, Ethiopia, between May 15, 2016, and May 15, 2020. In order to compare survival functions, Kaplan-Meier plots and the log-rank test were used. The Cox-PH model and Bayesian parametric survival models were then used to examine the survival time of breast cancer outpatients. The use of integrated layered Laplace approximation techniques has been made.

Results

The study included 382 outpatients with breast cancer in total, and 148 (38.7%) patients died. 42 months was the estimated median patient survival time. The Bayesian Weibull accelerated failure time model was determined to be suitable using model selection criteria. Stage, grade 2, 3, and 4, co-morbid, histological type, FIGO stage, chemotherapy, metastatic number 1, 2, and >=3, and tumour size all have a sizable impact on the survival time of outpatients with breast cancer, according to the results of this model. The breast cancer outpatient survival time was correctly predicted by the Bayesian Weibull accelerated failure time model.

Conclusions

Compared to high- and middle-income countries, the overall survival rate was lower. Notable variables influencing the length of survival following a breast cancer diagnosis were weight loss, invasive medullar histology, comorbid disease, a large tumour size, an increase in metastases, an increase in the International Federation of Gynaecologists and Obstetricians stage, an increase in grade, lymphatic vascular space invasion, positive regional nodes, and late stages of cancer. The authors advise that it is preferable to increase the number of early screening programmes and treatment centres for breast cancer and to work with the public media to raise knowledge of the disease's prevention, screening, and treatment choices.
The hidden hurdles of clinical clerkship: unraveling the types and distribution of professionalism dilemmas among South Korean medical students
Authors: Kang Ye Ji , Lin Yanyan , Rho Jaehee , Ihm Jungjoon , Kim Do-Hwan
Published: February 2024

Background

To improve the medical professionalism of medical students, it is essential to understand the dilemmas they face in various situations. This study explored the types and distribution of dilemmas Korean medical students encounter during their clinical clerkships. It then compared these with previous dilemma frameworks and identified the types and distribution of “complexity dilemmas,” wherein two dilemma themes emerge in a single clinical situation.

Methods

The researchers organized and recorded a group discussion with 106 third-year medical students who had completed their clinical clerkships. These students participated in the discussion as part of an assignment, focusing on the dilemmas they encountered during their clerkships. For data analysis and visualization, the researchers employed the MAXQDA software program and utilized the template analysis method, a qualitative research methodology.

Results

A total of seven dilemma themes and sixteen sub-themes were identified. The identity-related dilemma concerning student-doctors had the highest frequency. The themes “mismatch” and “Nun-chi” emerged as new additions not found in previous dilemma frameworks. The complexity dilemmas appeared in the sequence of “identity-dignity,” “identity-abuse,” and “identity-consent”.

Conclusions

To navigate the unique dilemmas present within South Korea’s clinical culture, several key issues need consideration: elevating the role of student-doctors, balancing the primary emphasis of educational hospitals on delivering medical services, and understanding interpersonal strategies, such as “Nun-chi”.
In situ simulation training strengthened bachelor of nursing students’ experienced learning and development process– a qualitative study
Authors: Karlsen Karina , Nygård Carina , Johansen Lisbeth Gaustad , Gjevjon Edith Roth
Published: February 2024

Background

In advanced clinical learning labs on campus, high-fidelity simulation has become an essential educational approach in the Bachelor of Nursing Education programme. However, simulation while in clinical placement, in situ, is rarely used in Bachelor of Nursing Education. The aim of the present study was to explore how in situ simulation training at a surgical hospital ward, according to Bachelor of Nursing students, influenced their learning and development process.

Methods

A qualitative descriptive study was conducted. Data were collected through individual interviews with a sample of 21 s-year Bachelor of Nursing students who completed 40 in situ simulations during their eight-week clinical placement at a Norwegian University Hospital. Data were analysed using inductive content analysis.

Results

The data analysis generated six subcategories constituting two descriptive categories: building professional confidence and internalising nursing knowledge. Although the students found in situ simulation stressful and uncomfortable for being assessed by student peers, the teacher and preceptor, the process of managing clinical situations in simulation helped build professional confidence. What the students had learned in the simulation was directly transferable to real clinical situations because they were in the hospital setting. The simulation sessions enabled them to connect theoretical knowledge and clinical skills. They could test their skills in a safe environment, performing procedures that made them aware of how their knowledge could be used in real life.

Conclusion

According to the Bachelor of Nursing students’ own experiences, in situ simulation supported the students’ learning process, connected theory and practice and contributed to developing confidence in the performance of clinical skills. Including simulation in clinical practice could prove to be an effective way of teaching and learning clinical skills in nursing regarding resources and learning outcomes.

Authors: Chen Xiuwen , Yue Liqing , Li Bingyu , Li Jun , Wu Xiuying , Peng Bin , Cao Ziwei
Published: February 2024

Background

The shortage of nurses has been a global human resources problem. A good professional growth environment is essential to developing potential nursing students and attracting nurses to join, and it has great significance in reducing nurse turnover. However, nurses’ comprehensive perceptions of professional growth have not yet been examined.

Methods

A cluster sampling method was used to conduct a professional growth questionnaire survey on young nursing talents from a large Chinese public tertiary A hospital in March 2022.

Results

The score of professional growth among 243 young nursing talents was 57.92 ± 9.607, with a scoring rate of 77.23%. The scores for dimensions of professional growth, from lowest to highest, were rehabilitation growth, promotion speed, professional goal progress, and professional ability development. Attitudes towards participating in training, service as the quality manager or clinical teacher, self-efficacy, professional title, work-family support, education, and organizational commitment of young nursing talents were significantly associated with professional growth.

Conclusion

The professional growth of young nursing talents was at a moderate level and needed to be strengthened. Nursing leaders and managers are expected to develop management practices to enhance young nursing talents’ professional growth in combination with the related factors.
Factors influencing contracting of residents with family doctors in China: a national cross-sectional survey
Authors: Zhao Ning , Gu Mei , Li Jin , Zhang Haiyan , Yang Jia
Published: February 2024

Background

Family doctor contract services (FDCS) have been introduced in China in 2009 [1] and rapidly expanded recently. This study sought to investigate factors that influenced the willingness of Chinese residents to use FDCS.

Methods

We employed multistage stratified and convenience sampling to administer questionnaires to 1455 Beijing, Qinghai, and Fujian residents. The willingness of residents in each province to contract family doctors was analyzed using the chi-square test and binary logistic regression.

Results

The analysis in this study found that the signing rate of family doctors in China was about 27.77%, with differences in the signing up levels in Beijing (13.68%), Fujian (64.49%) and Qinghai (11.22%). In addition, the binary logistic regression results emphasized the relative importance of age, education, medical preference and policy knowledge on the willingness to sign up. Distrust of family doctors’ medical skills (65.7%), not knowing how to contract (47.8%), and not knowing what medical problems can be solved (41.1%) were the top three reasons accounting for the reluctance of residents to contract with family doctors.

Conclusion

Residents from different backgrounds have different willingness to sign up, so the specific circumstances and needs of different groups should be taken into account. In order to increase the signing-up rate, consideration can be given to promoting the family doctor model in Fujian throughout the country. Individual hesitation can be eliminated by increasing the reimbursement rate of health insurance, reducing the out-of-pocket expenses of contracted patients, and providing incentives of certain discounts for consecutive contracted patients.
Challenges and opportunities in strengthening primary mental healthcare for older people in India: a qualitative stakeholder analysis
Authors: Kafczyk Tom , Hämel Kerstin
Published: February 2024

Background

Primary mental healthcare (PMHC) allows for complex mental health issues in old age to be addressed. India has sought to improve PMHC through legislation, strategies and programmes. This study analyses the challenges and opportunities involved in strengthening PMHC for older persons in India from the perspectives of key stakeholders.

Methods

Semistructured interviews were conducted with 14 stakeholders selected from the PMHC system in India and analysed using thematic analysis. First, the analysis was organizationally structured in accordance with the six WHO mental health system domains: (1) policy and legislative framework, (2) mental health services, (3) mental health in primary care, (4) human resources, (5) public information and links to other sectors, and (6) monitoring and research. Second, for each building block, challenges and opportunities were derived using inductive coding.

Results

This study highlights the numerous challenges that may be encountered when attempting to strengthen age-inclusive PMHC. Among these challenges are poor public governance, a lack of awareness and knowledge among policy-makers and other stakeholders, and existing policies that make unrealistic promises to weak primary healthcare (PHC) structures with an excessive focus on medicalizing mental health problems. Thus, the mental health system often fails to reach vulnerable older people through PHC. Established approaches to comprehensive, family- and community-oriented PHC support attempts to strengthen intersectoral approaches to PMHC that emphasize mental health promotion in old age. Targeting the PHC workforce through age-inclusive mental health education is considered particularly necessary. Experts further argue that adequate monitoring structures and public spending for mental health must be improved.

Conclusions

In this study, we aim to elaborate on the mental healthcare developments that may serve to achieve equity in access to mental healthcare in India. Coordinated and collaborative efforts by public and private stakeholders involved in the care of older persons, both with and without lived mental health experiences, as well as their families and communities, are necessary to bring the vision of those policies for PMHC to fruition. The findings presented in this study can also inform future research, policies and practice in other low- and middle-income countries.

Authors: Lloyd-Johnsen C. , Hampton A. , Stubbs E. , Moore S. , Eades S. , D’Aprano A. , Goldfeld S.
Published: February 2024

To better understand the specific influences of early life on the long-term health and well-being of local Aboriginal children in Alice Springs, high-quality local longitudinal data is required. The Central Australian Aboriginal Congress and the Murdoch Children's Research Institute are exploring the feasibility of establishing a cohort study to fill this gap. A nested qualitative study was conducted to identify priority issues that can be translated into research questions answerable through the proposed cohort study. Semi-structured interviews and focus group discussions (FGDs) were conducted with a range of key community stakeholders, parents and caregivers of young Aboriginal children from Alice Springs in the Northern Territory between 2020 and 2021. Two Aboriginal and two non-Aboriginal researchers conducted 27 interviews and 3 FGDs with 42 participants. Three broad themes were constructed through reflexive thematic analysis representing the areas of focus community stakeholders and parents want future research to prioritise: (1) social determinants of health (2) building positive connections, and (3) making sure kids grow up strong and healthy. Priority setting for future research should be driven by Aboriginal and Torres Strait Islander peoples in order to be of practical benefit to their community. This qualitative study found that housing, transport and positive connections through nurturing and engaged parents were some of the most important issues raised. Participants also wanted future research to focus on issues specific to children such as nutrition, hearing loss, language development and capacity to learn. These findings will guide future work led by local Aboriginal researchers to co-design the proposed cohort study.
Time series analysis of malaria cases to assess the impact of various interventions over the last three decades and forecasting malaria in India towards the 2030 elimination goals
Authors: Singh Mrigendra P. , Rajvanshi Harsh , Bharti Praveen K. , Anvikar Anup R. , Lal Altaf A.
Published: February 2024

Background

Despite the progress made in this decade towards malaria elimination, it remains a significant public health concern in India and many other countries in South Asia and Asia Pacific region. Understanding the historical trends of malaria incidence in relation to various commodity and policy interventions and identifying the factors associated with its occurrence can inform future intervention strategies for malaria elimination goals.

Methods

This study analysed historical malaria cases in India from 1990 to 2022 to assess the annual trends and the impact of key anti-malarial interventions on malaria incidence. Factors associated with malaria incidence were identified using univariate and multivariate linear regression analyses. Generalized linear, smoothing, autoregressive integrated moving averages (ARIMA) and Holt’s models were used to forecast malaria cases from 2023 to 2030.

Results

The reported annual malaria cases in India during 1990–2000 were 2.38 million, which dropped to 0.73 million cases annually during 2011–2022. The overall reduction from 1990 (2,018,783) to 2022 (176,522) was 91%. The key interventions of the Enhanced Malaria Control Project (EMCP), Intensified Malaria Control Project (IMCP), use of bivalent rapid diagnostic tests (RDT-Pf/Pv), artemisinin-based combination therapy (ACT), and involvement of the Accredited Social Health Activists (ASHAs) as front-line workers were found to result in the decline of malaria significantly. The ARIMA and Holt’s models projected a continued decline in cases with the potential for reaching zero indigenous cases by 2027–2028. Important factors influencing malaria incidence included tribal population density, literacy rate, health infrastructure, and forested and hard-to-reach areas.

Conclusions

Studies aimed at assessing the impact of major commodity and policy interventions on the incidence of disease and studies of disease forecasting will inform programmes and policymakers of steps needed during the last mile phase to achieve malaria elimination. It is proposed that these time series and disease forecasting studies should be performed periodically using granular (monthly) and meteorological data to validate predictions of prior studies and suggest any changes needed for elimination efforts at national and sub-national levels.

Given the rarity of RAD51C mutations, the risk and treatment of metachronous breast cancer after the diagnosis of ovarian cancer in RAD51C mutation carriers is not clear, especially for those who have received PARPi treatment. We report the case of a 65-year-old woman diagnosed with stage IIIC high-grade serous primary fallopian tube cancer. The patient had no family history of breast or ovarian cancer. The patient received three cycles of neoadjuvant chemotherapy with paclitaxel and carboplatin and achieved a complete response. After interval debulking surgery, the patient received three cycles of adjuvant chemotherapy. Collection and extraction of saliva DNA for next-generation sequencing identified a RAD51C mutation c.838-2 A > G. The patient received niraparib as front-line maintenance treatment. After 36 months of niraparib treatment, the patient had grade II invasive ductal carcinoma of the left breast that was positive for estrogen receptor (90%) and Ki-67 (30%) and negative for progesterone receptor and human epidermal growth factor receptor 2. Computed tomography revealed the absence of distant metastases. Modified radical mastectomy and axillary lymph node dissection were then performed. The final pathological report of the breast showed a 1.8 cm Bloom-Richardson grade II invasive ductal carcinoma in the left breast with axillary lymph node metastasis (1/21). Finally, the breast cancer was stage IIA, pT1cN1M0. The metachronous breast cancer in this case may be the first report of second primary cancer in fallopian tube cancer patient harboring a RAD51C mutation during niraparib treatment. Further studies are required to determine optimal treatment.

Background

Rheumatoid arthritis (RA) is typically preceded by an extended preclinical period where circulating autoantibodies, particularly anti-citrullinated protein antibodies (ACPA), are detectable in the absence of clinical arthritis. Increased dietary intake of anti-inflammatory omega-3 (ω3) polyunsaturated fatty acids (PUFA) has been shown to be associated with a lower the risk of developing incident RA in large epidemiological studies. It is currently not known how changes in fatty acid (FA) metabolism may impact on the progression towards RA in at-risk individuals. To begin to address this question, we profiled serum FAs and oxylipins in an established cohort of at-risk ACPA-positive first-degree relatives (FDR) of RA patients (N = 31), some of whom developed RA (N = 4), and compared their profile to ACPA-negative FDR from the same population (N = 10).

Methods

Gas chromatography (GC) was used for FA quantitation. Oxylipins were extracted and quantified using high-performance liquid chromatography–tandem mass spectrometry (HPLC/MS/MS).

Results

Although we did not detect any meaningful differences in overall FA content between ACPA + and ACPA − FDR, the levels of oxylipins derived from FA metabolism demonstrated significant differences between the two groups, with the ACPA + group demonstrating enrichment in circulating arachidonic acid- and eicosapentaenoic acid-derived molecules. Compared with the ACPA − FDR group, the ACPA + FDR, including those who progressed into inflammatory arthritis, displayed higher levels of LOX-derived oxylipins.

Conclusion

ACPA seropositivity in otherwise unaffected individuals at-risk for developing future RA based on family history (FDR) is associated with alterations in the serum oxylipin profile that suggests dysregulated LOX activity.

Objective

Carbapenemase production and biofilm formation in K. pneumoniae are crucial factors influencing the pathogenicity and antibiotic resistance of this bacterium. This study investigated the interplay between carbapenemase production and biofilm formation in K. pneumoniae clinical isolates.

Results

The distribution of biofilm-forming ability significantly differed between carbapenemase-producing (CP-Kp) (n = 52) isolates and carbapenemase-nonproducing (CN-Kp) isolates (n = 37), suggesting a potential link between carbapenemase production and biofilm formation. All the blaNDM-1-harbouring isolates demonstrated biofilm formation, with varying levels classified as strong (33.33%), moderate (22.22%), or weak (44.45%). blaNDM-1 and blaKPC-coharbouring isolates did not exhibit strong or moderate biofilm formation. blaNDM-1 and blaOXA-48-coharbouring isolates were predominantly moderate (48.65%), followed by weak (32.43%), with none showing strong biofilm production. These findings suggest a correlation between the presence of carbapenemases and biofilm-forming ability; however, the heterogeneity in biofilm-forming abilities associated with different carbapenemase types and the absence of strong biofilm producers in the detected carbapenemase combinations prompt a closer look at the complex regulatory mechanisms governing biofilm formation in CP-Kp isolates.
Non-specific irreversible 89Zr-mAb uptake in tumours: evidence from biopsy-proven target-negative tumours using 89Zr-immuno-PET

Background

Distribution of mAbs into tumour tissue may occur via different processes contributing differently to the 89Zr-mAb uptake on PET. Target-specific binding in tumours is of main interest; however, non-specific irreversible uptake may also be present, which influences quantification. The aim was to investigate the presence of non-specific irreversible uptake in tumour tissue using Patlak linearization on 89Zr-immuno-PET data of biopsy-proven target-negative tumours. Data of two studies, including target status obtained from biopsies, were retrospectively analysed, and Patlak linearization provided the net rate of irreversible uptake (Ki).

Results

Two tumours were classified as CD20-negative and two as CD20-positive. Four tumours were classified as CEA-negative and nine as CEA-positive. Ki values of CD20-negative (0.43 µL/g/h and 0.92 µL/g/h) and CEA-negative tumours (mdn = 1.97 µL/g/h, interquartile range (IQR) = 1.50–2.39) were higher than zero. Median Ki values of target-negative tumours were lower than CD20-positive (1.87 µL/g/h and 1.90 µL/g/h) and CEA-positive tumours (mdn = 2.77 µL/g/h, IQR = 2.11–3.65).

Conclusion

Biopsy-proven target-negative tumours showed irreversible uptake of 89Zr-mAbs measured in vivo using 89Zr-immuno-PET data, which suggests the presence of non-specific irreversible uptake in tumours. Consequently, for 89Zr-immuno-PET, even if the target is absent, a tumour-to-plasma ratio always increases over time.
Differing impacts of the COVID-19 pandemic on farmers and intermediaries: insights into the Ecuadorian cocoa value chain

The COVID-19 pandemic generated diverse impacts and responses in agricultural value chains worldwide. Cocoa is a key crop for Ecuadorian exports, and the analysis of effects the pandemic had on value chain actors contributes to the understanding of their individual capacities to coping with a major shock. The purpose of this study was to assess the number and severity of impacts and responses implemented by two links in the cocoa value chain to the pandemic, based on a survey of 158 cocoa farmers and 52 cocoa intermediaries from the main cocoa-producing provinces of the northern coast of Ecuador in 2021. Surveyed farmers and part of the intermediaries form part of the sustainability program of a large Swiss chocolate manufacturer. The impacts and responses reported were grouped into seven resources according to the Activity System Approach. Then, a comparison between groups was applied using the Wilcoxon rank sum test for nonparametric data, determining the most severe impacts and effective resilience responses among the actors. The results reveal that farmers and intermediaries were similarly affected by the pandemic, reporting 21 and 16 negative impacts, respectively. Farmers experienced a higher number and severity of impacts on financial and social resources, while intermediaries on human and material resources. The strongest impact was the loss of sales, reported by 65% of farmers and 58% of intermediaries. Farmers implemented more social responses that they judged highly effective, while intermediaries implemented more human responses that they judged highly effective. Public policy should enhance the social resources of farmers by strengthening their associativity and the capacities of their members, as mechanisms to mitigate their vulnerability to future health and climate crises. The financial resources of both actors should be protected through public credit and agricultural insurance.
Futures participation as anticipatory practice — what do futures workshops do?
Authors: Armanto Anna Riikka Airiina
Published: February 2024

Futures workshop is a participatory futures research method for producing views on futures and facilitating transformation and empowerment. Since different workshop methods are generally considered to have many advantages, they are widely used in various futures contexts. However, there is little knowledge on how futures participation entails empowerment for thinking and acting on futures. This paper studies participants’ futures thinking and action in relation to their workshop experience. As psychological constructs for engaging with futures, the concepts of human agency and futures consciousness are used for the analysis. The study examines two futures workshops organized in Finland for farmers and stakeholders in the agricultural sector using the futures consciousness scale pre-post survey, an open-ended follow-up survey, and thematic interviews. The results of the study show that although there was no statistically significant change in futures consciousness, the workshop experience is absorbed into participants’ daily reality, provoking their uses of futures. By analyzing quantitative and qualitative data, it is thus concluded that the ways in which futures participation empowers futures thinking and action are not, and should not be held, evident. Therefore, it is proposed that regarding their empowerment assumptions, participatory futures methods should perform deeper self-consideration as anticipatory practice.
