HUNCHEST projects-advancing low-dose CT lung cancer screening in Hungary.

Lung cancer, the leading cause of malignancy-related deaths worldwide, demands proactive measures to mitigate its impact. Low-dose computer tomography (LDCT) has emerged as a promising tool for secondary prevention through lung cancer screening (LCS). The HUNCHEST study, inspired by the success of international trials, including the National Lung Cancer Screening Trial and the Dutch NELSON study, embarked on the first LDCT-based LCS program in Hungary. The initiative assessed the screening efficiency, incorporating lung function tests and exploring the interplay between lung cancer and chronic obstructive pulmonary disease (COPD). Building upon this foundation, an implementation trial involving 18 Hungarian centers supported by the Ministry of Human Capacities demonstrated the feasibility of LCS within a multicentric framework. These centers, equipped with radiology capabilities, collaborated with multidisciplinary oncology teams, ensuring optimal patient pathways. However, a critical challenge remained the patient recruitment. To address this, the HUNCHEST 3 project, initiated in 2023, seeks to engage general practitioners (GPs) to reach out to eligible patients within a municipality collective of 60 thousand inhabitants. The project's ultimate success is contingent upon the willingness of eligible individuals to undergo LDCT scans. In conclusion, the HUNCHEST program represents a crucial step in advancing lung cancer screening in Hungary. With a focus on efficiency, multidisciplinary collaboration, and innovative patient recruitment strategies, it endeavors to contribute to the reduction of lung cancer mortality and serve as a blueprint for potential nationwide LCS programs.

Newborn screening-detected 21-hydroxylase deficiency: growth pattern is not associated with the genotype.

Normalizing growth in children with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHD-CAH) requires a long-term maintenance of a fragile balance between hydrocortisone (HC) replacement and androgen suppression. The growth pattern in children with 21OHD-CAH diagnosed by clinical symptoms has been evaluated in numerous retrospective studies. The aim of this study was to evaluate growth of patients with 21OHD-CAH detected by newborn screening (NBS), prior to clinical symptoms. Nation-wide NBS for 21OHD-CAH was implemented in the Czech Republic in 2006. Since then, 1,317,987 neonates were screened (2006-2017) and 21OHD-CAH was confirmed in 108 patients. Growth was evaluated as height-standard deviation score (SDS) at regular time-points, related to bone age and compared to recent population standards. In 88 patients, available data allowed long-term evaluation of growth, HC and fludrocortisone doses (in half-year intervals), with a median observation period of ten years. Body height in affected children was shorter between years 1-9 of life with a nadir at age 1-3 years. Their height did not differ from general population at the age 10-12 years. There were not found differences according to 21OHD-CAH severity. NBS is an effective secondary prevention tool for the early detection of 21OHD-CAH which improves growth patterns. A significant growth deceleration was observed during infancy and early childhood periods but with following height normalization. Growth pattern was not associated with the genotype of 21OHD, if patients have been detected by NBS.

Clinical use of the Onclarity test with extended HPV genotyping and phenotyping in patients with suspected squamous intraepithelial lesions.

Human papillomavirus (HPV) is the most widespread virus with oncogenic potential that infects humans and there is a need to look for the most effective screening method among the population. Understanding the role of HPV in cervical dysplasia and viruses typing increased the usage of HPV-based cervical cancer screening tests using genotyping. We aim to assess the usefulness the Onclarity Test with extended genotyping and phenotyping of HPV in detecting cervical squamous intraepithelial lesions in 695 subjects who registered for regular cervical screening or due to abnormal LBC result or positive HPV results. Incidence of positive HPV depended significantly on biopsy outcome (p < 0.001). It was the highest for patients with HSIL (92.5%), lower for patients with LSIL (57.9%) and with HPV outcome of biopsy (50.0%). The sensitivity of positive HPV for detecting HSIL was equal to 92.50% (95% CI: 79.61%-98.43%), and specificity equalled 55.26% (95% CI: 43.41-66.69%). Sensitivity of HPV positive for any of 16, 18, 31, 45, 51 or 52 genotypes but not belonging to the P1, P2 or P3 group for detecting HSIL equalled 62.50% (95% CI: 45.80-77.27%), specificity equalled 72.37% (95% CI: 60.91-82.01%). The Onclarity test is characterised by high sensitivity and specificity in detecting CIN2+ lesions. Extended genotyping enables the identification of the most common oncogenic HPV types in the population. It can be used as a basic tool for secondary prevention or together with LBC.

Lupus, antiphospholipid syndrome, and stroke: An attempt to crossmatch.

Cerebrovascular accidents (CVAs) or strokes are part of the common thrombotic manifestations of Systemic Lupus Erythematosus (SLEs) and Antiphospholipid syndrome (APS). Such neurological thrombotic events tend to occur in patients with SLE at a higher frequency when Antiphospholipid antibodies (aPLs) are present, and tend to involve the large cerebral vessels. The mechanism of stroke in SLE can be driven by complement deposition and neuroinflammation involving the blood-brain barrier although the traditional cardiovascular risk factors remain major contributing factors. Primary prevention with antiplatelet therapy and disease activity controlling agent is the basis of the management. Anticoagulation via warfarin had been a tool for secondary prevention, especially in stroke recurrence, although the debate continues regarding the target international normalized ratio (INR). The presence of either of the three criteria antiphospholipid antibodies (aPLs) and certain non-criteria aPL can be an independent risk factor for stroke. The exact mechanism for the involvement of the large cerebral arteries, especially in lupus anticoagulant (LAC) positive cases, is still to be deciphered. The data on the role of non-criteria aPL remain very limited and heterogenous, but IgA antibodies against β2GPI and the D4/5 subunit as well as aPS/PT IgG might have a contribution. Anticoagulation with warfarin has been recommended although the optimal dosing or the utility of combination with antiplatelet agents is still unknown. Minimal data is available for direct oral anticoagulants (DOACs).

A Meta-Analysis of eHealth Interventions on Ischaemic Heart Disease Health Outcomes.

Electronic Health (eHealth) interventions as a secondary prevention tool to empower patients' health in decision-making and behaviour. With the growing body of evidence supporting the use of eHealth interventions, the intention is to conduct a meta-analysis on various health outcomes of eHealth interventions among ischaemic heart disease (IHD) patients. Based on PRISMA guidelines, eligible studies were searched through databases of Web of Science, Scopus, PubMed, EBSCOHost, and SAGE (PROSPERO registration CRD42021290091). Inclusion criteria were English language and randomised controlled trials published between 2011 to 2021 exploring health outcomes that empower IHD patients with eHealth interventions. RevMan 5.4 was utilised for meta-analysis, sensitivity analysis, and risk of bias (RoB) assessment while GRADE software for generating findings of physical health outcomes. Non-physical health outcomes were analysed using SWiM (synthesis without meta-analysis) method. This review included 10 studies, whereby, six studies with 895 participants' data were pooled for physical health outcomes. Overall, the RoB varied significantly across domains, with the majority was low risks, a substantial proportion of high risks and a sizeable proportion of unclear. With GRADE evidence of moderate to high quality, eHealth interventions improved low density lipoprotien (LDL) levels in IHD patients when compared to usual care after 12 months of interventions (SMD -0.26, 95% CI [-0.45, -0.06], I2 = 0%, p = 0.01). Significance appraisal in each domain of the non-physical health outcomes found significant findings for medication adherence, physical activity and dietary behaviour, while half of the non-significant findings were found for other behavioural outcomes, psychological and quality of life. Electronic Health interventions are found effective at lowering LDL cholesterol in long-term but benefits remain inconclusive for other physical and non-physical health outcomes for IHD patients. Integrating sustainable patient empowerment strategies with the advancement of eHealth interventions by utilising appropriate frameworks is recommended for future research.

Perceived Barriers to Cervical Cancer Screening Using Pap Smear Test among Women Attending Saad Abu Al Ella Hospital in Khartoum State, 2022

Background: Cervical cancer is the second common cancer among women worldwide. It is a preventable cancer, and early detection of precancerous conditions through the Papanicolaou cytology screening (Pap smear) is a key aspect of prevention; it is accepted worldwide as an efficient tool for secondary prevention. While the PS test is simple, inexpensive, and relatively reliable as a method of diagnosing cervical cancer, most women do not take the test. Therefore, this study is sought to describe the barriers to pap smear uptake among Sudanese women. Materials and Method: This total coverage observational, analytical and cross sectional, hospital-based study was conducted in Saad Abu El Ella Hospital in April 2022. The study was conducted using an anonymous questionnaire to assess the perceived barriers of 93 participants. All data were computerized using Microsoft Excel’17 and the data were described and analyzed using statistical package for social science (SPSS23). Results: The findings revealed that the mean age of the participants was 39.5 years and only 3.2% had ever undergone a pap smear test. Identified barriers were lack of information, not knowing where to go, and fear of pain. The majority, 72% are willing to routinely perform a pap smear test if well informed about it. The study also demonstrates that there is a significant correlation between perceived barriers score and willingness to perform the pap smear test (p value = 0.008), and between the perceived barriers score and the sociodemographic factors: Age (p value = 0.006), educational level (p value = 0.028) and occupation (p value = 0.040), but no association with the economic status was found (p value = 0.378). Conclusion: The detection rate is too low compared to the national target of over 70%. Therefore, more work is needed to reduce perceived barriers to cervical cancer screening by providing education/raising for popular awareness; addressing misconceptions and false beliefs; informing women about the necessity and importance of Pap smear; and health promotion using mass media such as national television, social media, radio, billboards, and newspapers and other print media.

The workload-indexed blood pressure response predicts cardiovascular events and all-cause mortality in coronary artery disease

Abstract Background Abnormal blood arterial pressure response to exercise (BPR) is a cardiovascular (CV) risk factor (CVRF). The concept of pathological BPR, believed to be an excessive raise or decrease, has been challenged. The workload-indexed blood pressure response (WBPR) recently emerged in an attempt to normalize hypertensive responses to exercise. However, it remains to be explored its value in high-risk CV subjects. Purpose Evaluation of the predictive value of WBPR in the occurrence of CV events and death in coronary artery disease (CAD) patients. Methods A cohort of 318 patients with known CAD, who underwent Bruce protocol treadmill testing between 2009–2010, were retrospectively followed to 11/2021 (9.9±2.3 years) to assess the predictive value of WBPR for the occurrence of death and CV events. The WBPR is the ratio between systolic blood pressure variation from rest to peak exercise (ΔSBP) and metabolic equivalent of task (MET-1). High and low WBPR groups were created based on median value for this sample (5.2 mmHg/MET). Data presented: mean ± standard deviation; 95% confidence interval (CI) for hazard ratios (HR); significance between groups p&amp;lt;0.05. Results Low vs high WBPR groups were similar at baseline for sex (88% male, p=0.67), hypertension (63%, p=0.18), diabetes (32%, p=0.34); dyslipidemia (72%, p=0.62), myocardial infarction (75%, p=0.39) and heart failure (HF) (9.9%, p=0.07), with exception for overweight/obesity (90% vs 82%, p=0.009) and age (57±11 vs 61±8 years, p=0.009) that were higher in the high-WBPR group. No significant differences were found between groups for medication at baseline, including anti-hypertensive, anti-thrombotic or anti-ischemic drugs. In the follow-up period occurred 43 deaths (12 CV deaths), 58 reinfarctions, 94 worsening/de novo HF and 29 strokes. A non-linear J-shaped relationship was observed between WBPR and most events. In the event-free survival analyses using Cox regression, the high-WBPR group was associated with all death (HR 2.0 (CI 1.0–3.9, p=0.042), reinfarction (HR 2.3 (CI 1.2–4.1, p=0.008), and worsening/de novo HF (HR 1.7 (CI 1.0–2.9, p=0.043) after adjusting for baseline age, CVRFs and medication. In receiver operating characteristic curves, adding WBPR to a model with other cardiac stress variables (double product, ST-T changes, symptoms, and test positivity) significantly improved the power to predict all death, with an area under curve of 0.73 (CI 0.66–0.80, p=0.037). Conclusions Data shows that WBPR is a powerful independent predictor of future cardiovascular events and deaths in CAD patients. This highlights cardiac exercise stress testing as an important risk assessment tool in secondary prevention of cardiovascular disease. Funding Acknowledgement Type of funding sources: None.

Occupational hand and wrist disorders among forestry workers: An exposed-control study to investigate preventive strategies.

In the arboriculture sector, some activities are still manually performed by forestry workers, which result consequently exposed to a high risk of developing muscle skeletal disorders. The Italian Compensation Authority reported an increase of work-related tendinopathies and carpal tunnel syndrome in loggers, but screening protocols are not available yet. The objectives were: a) to evaluate the prevalence of tendinopathies and carpal tunnel syndrome in a sample of loggers and b) identify a sound screening approach. 41 loggers and 41 paired control workers were recruited for a total of 164 hands. The protocol included 1) demographic data; 2) medical history; 3) identification of CTS symptoms through a questionnaire and a hand-chart; 4) upper limbs clinical examination; 5) Raynaud's diseases questionnaire; 6) wrists ultrasound; 7) NCS of the distal median nerve. The prevalence of tendinopathies was statistically significant only in the non-dominant hand (75, 5% in the exposed group and 53, 6% in the non-exposed group). The prevalence of CTS was 32, 2% in the exposed group and 15, 5% in the non-exposed group. The questionnaire had a sensitivity of 56, 7% and a specificity of 75%. The hand-chart had a sensitivity of 30% and a specificity of 92%. The clinical examination had sensitivity of 30% and specificity of 80%. The ultrasound had a sensitivity of 70% and a specificity of 56%. Loggers are a population at risk of occupational hand and wrist disorders. The hand-chart could be considered, together with the questionnaire, as the best secondary prevention tool to diagnose CTS.

Expanded Newborn Screening in Italy Using Tandem Mass Spectrometry: Two Years of National Experience.

Newborn screening (NBS) for inborn errors of metabolism is one of the most advanced tools for secondary prevention in medicine, as it allows early diagnosis and prompt treatment initiation. The expanded newborn screening was introduced in Italy between 2016 and 2017 (Law 167/2016; DM 13 October 2016; DPCM 12-1-2017). A total of 1,586,578 infants born in Italy were screened between January 2017 and December 2020. For this survey, we collected data from 15 Italian screening laboratories, focusing on the metabolic disorders identified by tandem mass spectrometry (MS/MS) based analysis between January 2019 and December 2020. Aminoacidemias were the most common inborn errors in Italy, and an equal percentage was observed in detecting organic acidemias and mitochondrial fatty acids beta-oxidation defects. Second-tier tests are widely used in most laboratories to reduce false positives. For example, second-tier tests for methylmalonic acid and homocysteine considerably improved the screening of CblC without increasing unnecessary recalls. Finally, the newborn screening allowed us to identify conditions that are mainly secondary to a maternal deficiency. We describe the goals reached since the introduction of the screening in Italy by exchanging knowledge and experiences among the laboratories.

Determinants of Functional Improvement After Cardiac Rehabilitation in Acute Coronary Syndrome.

IntroductionCardiac rehabilitation (CR) is an effective tool for secondary prevention after acute coronary syndrome (ACS).AimAim of our study was to find the significant determinants of exercise capacity (evaluated with the six-minute walking test—6-MWT) and functional improvement in patients undergoing CR after an ACS.MethodsThe study group included 298 patients (mean age 61.6 ± 10.2 years; males 80.2%) who, after ACS, were enrolled in CR program at Niguarda Hospital in Milan from 2015 to 2018. For all patients, we collected anamnestic, clinical and instrumental cardiological data. All patients performed a 6-MWT at the beginning (6-MWT-1) and at the end (6-MWT-2) of CR program. Δ meters were used to represent functional improvement.ResultsMultiple linear regression models were carried out for 6-MWT-1, 6-MWT-2, Δ meters and % Δ meters. Standardized regression coefficients showed that age (β = − 0.237; p < 0.001), BMI (β = − 0.116; p = 0.006) and heart rate (β = − 0.082; p = 0.040) were determinants of exercise capacity (6MWT-1 and 2), whereas age (β = −.231; p = 0.004), sex (β = − 0.187; p = 0.008) and BMI (β = − 0.164; p = 0.022) were determinants of functional improvement (Δ meters).ConclusionsOur data showed that functional improvement after CR in ACS patients is mainly related to non-cardiological variables. Instead it is related to intrinsic factors, both modifiable (BMI) and non-modifiable (age, sex).Supplementary InformationThe online version contains supplementary material available at 10.1007/s40292-021-00473-7.

Albuminuria and polyvascular disease improve multivariate predictive models after an acute cardiovascular event. The AIRVAG cohort

Background and aimsThere is no consensus regarding risk stratification tools for secondary prevention in atherosclerotic cardiovascular disease. Our aim was to compare the discriminative performance of the Framingham, REGICOR, SCORE, and REACH risk functions and the Bohula-TIMI and SMART risk scores, as well as to assess the potential added value of other clinical variables for the prediction of recurrent events in patients with established vascular disease. MethodsA cohort of 269 patients with established vascular disease (52.8% coronary, 32% cerebrovascular, 15.2% PAD) was included. The survival functions of risk groups (low/medium/high) according to commonly used cutoff points for each function/score were compared, and hazard ratios for each were estimated using Cox regression. We calculated Δ Harrell’s C statistic, cat-NRI, and cNRI after adding new predictors to a base model including age, sex, total cholesterol, current smoking status, hypertension, and diabetes. ResultsAfter six years of follow-up (median 4.82 years), 61 events occurred (23%). High-risk groups had a higher risk of recurrent event: SMART (HR: 3.17 [1.55−6.5]), Framingham (HR: 3.08 [1.65−5.75]), REGICOR (HR: 2.71 [1.39−5.27]), SCORE (HR: 2.14 [1.01−4.5], REACH (HR: 5.74 [2.83−11.7]), B-TIMI (HR: 3.68 [0.88−15.3]). Polyvascular disease (three territories HR: 5.6 [2.2−14.25]), albuminuria (HR: 3.55 [2.06−6.11]), and heart failure (HR: 3.11 [1.34−7.25]) also increased risk. Discrimination (Harrell’s C) was low but improved after adding albuminuria and polyvascular disease. Both variables also improved the performance of the base model (cNRI.326 [.036; .607]). ConclusionsThe Framingham, REGICOR, SCORE, and REACH functions and the B-TIMI and SMART scores showed low yet similar performance in secondary prevention. Albuminuria and polyvascular disease improved the predictive performance of major classical cardiovascular risk factors.

Designing a Health Coach-Augmented mHealth System for the Secondary Prevention of Coronary Heart Disease Among Women

While the number of women with Coronary Heart Disease requiring cardiac rehabilitation (CR) continues to increase, lack of access and other barriers to center-based CR present significant challenges. A mobile phone and wearable device-based technological system can offer home-based secondary prevention program for CHD. We have designed a women-specific digital health intervention system for use in a home-based CR program. The system that we have proposed combines human-expert intelligence with machine intelligence to enhance the decision-making capability of a health coach. We have evaluated the prototype of our system with eight women with CHD for over 13 weeks. The evaluation has shown a significant positive impact of preprogrammed intervention messages on participants’ walking performance on the same and the next day. Since increased walking activities directly improve heart health, we can directly infer that our proposed system is beneficial as a tool for secondary prevention among women with CHD.

Newborn screening-detected 21-hydroxylase deficiency: growth pattern is not associated with the genotype.

Normalising growth in children with congenital adrenal hyperplasia due to 21- hydroxylase deficiency (21OHD-CAH) requires a long-term maintenance of a fragile balance between hydrocortisone (HC) replacement and androgen suppression. The growth pattern inchildren with 21OHD-CAH diagnosed by clinical symptoms has been evaluated in numerous retrospective studies. The aim of this study was to evaluate growth of patients with 21OHD-CAH detected by newborn screening (NBS), prior to clinical symptoms. Nation-wide NBS for 21OHD-CAH was implemented in the Czech Republic in 2006. Since then, 1,317,987 neonates were screened (2006-2017) and 21OHD-CAH was confirmed in 108 patients. Growth was evaluated as height-standard deviation score (SDS) at regular time-points, related to bone age and compared to recent population standards. In 88 patients, available data allowed long-term evaluation of growth, HC and fludrocortisone doses (in half-year intervals), with a median observation period of ten years. Body height in affected children was shorter between years 1-9 of life with a nadir at age 1-3 years. Their height did not differ from general population at the age 10-12 years. There were not found differencies according to 21OHD-CAH severity. NBS is an effective secondary prevention tool for the early detection of 21OHD-CAH which improves growth patterns. A significant growth deceleration was observed during infancy and early childhood periods but with following height normalization. Growth pattern was not associated with the genotype of 21OHD, if patients have been detected by NBS.

Meckel-Gruber Syndrome: A Case Report at RHUH

A rare lethal autosomal recessive condition called Meckel-Gruber Syndrome (MGS) has a clinical and genetical heterogenicity. A 15-year-old primigravid presented at the 16th gestational week of her pregnancy at the Rafic Hariri University Hospital (RHUH) for antenatal ultrasonography. She had a third degree consanguineous marriage with no previous uterine scars, no previous invasive testing, no previous fetal anomaly, no comorbidities and no family history of congenital anomalies. On the other hand, her current pregnancy was not the result of an Artificial Reproductive technique (ART) and her medication at home was only based on vitamins and calcium. The antenatal ultrasonography showed the following features: (1) occipital encephalocele (2) diffuse subcutaneous edema (3) bilateral dysplastic kidneys and the bladder was not visualized. These features were suggestive of Meckel Gruber Syndrome (MGS). We concluded that ultrasound in the context of genetic diseases, especially our MGS case, is considered as a secondary prevention tool.

Epidemiology of rare diseases detected by newborn screening in the Czech Republic.

Presymptomatic detection of patients with rare diseases (RD), defined by a population frequency less than 1 : 2,000, is the task of newborn screening (NBS). In the Czech Republic (CZ), currently eighteen RD are screened: phenylketonuria/hyperphenylalaninemia (PKU/HPA), congenital hypothyroidism (CH), congenital adrenal hyperplasia (CAH), cystic fibrosis (CF), medium chain acyl-CoA dehydrogenase deficiency (MCADD), long chain 3-hydroxyacyl-CoA dehydrogenase deficiency (LCHADD), very long chain acyl-CoA dehydrogenase deficiency (VLCADD), carnitine palmitoyl transferase I and II deficiency (CPTID, CPTIID), carnitine-acylcarnitine translocase deficiency (CACTD), maple syrup urine disease (MSUD), glutaric aciduria type I (GA I), isovaleryl-CoA dehydrogenase deficiency (IVA), argininemia (ARG), citrullinemia (CIT), biotinidase deficiency (BTD), cystathionine beta-synthase-deficient homocystinuria (CBSD HCU), and methylenetetrahydrofolate reductase deficiency homocystinuria (MTHFRD HCU). The aim was to analyze the prevalence of RD screened by NBS in CZ. We examined the NBS programme in CZ from 1 January 2010 to 31 December 2017, which covered 888,891 neonates. Dried blood spots were primarily analyzed using fluorescence immuno-assay, tandem mass spectrometry and fluorimetry. The overall prevalence of RD among the neonate cohort was 1 : 1,043. Individually, 1 : 2,877 for CH, 1 : 5,521 for PKU/HPA, 1 : 6,536 for CF (1 : 5,887 including false negative patients), 1 : 12,520 for CAH, 1 : 22,222 for MCADD, 1 : 80,808 for LCHADD, 1 : 177,778 for GA I, 1 : 177,778 for IVA, 1 : 222,223 for VLCADD, 1 : 296,297 for MSUD, 1 : 8,638 for BTD, and 1 : 181,396 for CBSD HCU. The observed prevalence of RD, based on NBS, corresponds to that expected, more precisely it was higher for BTD and lower for MSUD, IVA, CBSD HCU, MCADD and VLCADD. Early detection of rare diseases by means of NBS is an effective secondary prevention tool.

Indication of prophylactic vaccines as a tool for secondary prevention in HPV-linked disease.

To determine whether quadrivalent HPV vaccination is effective in reducing recurrent disease in women with a previous history of HPV disease. All women under 45years of age treated for HPV-linked disease and with negative HPV test, cytology and colposcopy 3months after treatment were enrolled. Women were randomly assigned into two groups: a group that received HPV vaccine post treatment and a group that was only submitted to follow-up. Follow-up was performed every 6months for a duration of at least 3years. Kaplan-Meier curve was used to estimate the overall disease-free survival during the follow-up period. Statistical analysis was performed by Fisher's exact test. From November 2013 to October 2014, we enrolled a total of 178 women at Careggi University Hospital in Florence and at Azienda USL in Massa Carrara. 12 out of 89 patients in the non-vaccination group recurred (13.5%), while 3 out of 89 patients in the vaccination group recurred (3.4%). The Kaplan-Meier curves showed a statistically difference in the log rank test (p = 0.0147) for the overall disease-free survival in the study groups during follow-up. The rate of recurrence was significantly higher in the non-vaccination group, with a p = 0.0279 by Fisher exact test. The introduction of anti-HPV vaccination during the follow-up post treatment for HPV-linked disease is recommended to reduce the risk of recurrence. The clinical implication of this could be very important to influence post-treatment management of HPV disease.

Probability of Heat Intolerance: Standardized Interpretation of Heat-Tolerance Testing Results Versus Specialist Judgment.

The heat-tolerance test (HTT) is a screening tool for secondary prevention of exertional heat illness by the Israel Defense Forces. To discern participant tolerance, recruits are exposed to intermediate environmental and exercise stresses, and their physiological responses, core temperature, and heart rate are monitored. When their physiological measures rise at a higher rate or exceed the upper levels of absolute values compared with other participants, heat intolerance (HI) is diagnosed. To develop a mathematical model to interpret HTT results and provide a quantitative estimate of the probability of heat tolerance (PHT). Cross-sectional study. Warrior Health Research Institute. The HTT results of 175 random individuals tested after an episode of exertional heat illness were classified qualitatively and then divided into training (n = 112) and testing (n = 63) datasets. All individuals were male soldiers (age range = 18-22 years) who had sustained an episode of definitive or suspected exertional heat stroke. Based on the decision algorithm used by the Israel Defense Forces for manual interpretation of the HTT, we designed a logistic regression model to predict the heat-tolerance state. The model used a time series of physiological measures (core temperature and heart rate) of individuals to predict the manually assigned diagnosis of HT or HI. It was initially fitted and then tested on 2 separate, random datasets. The model produced a single value, the PHT, and its predictive ability was demonstrated by prediction-density plots, receiver operating characteristic curve, contingency tables, and conventional screening test evaluation measures. According to prediction-density plots of the testing set, all HT patients had a PHT of 0.7 to 1. The receiver operating characteristic curve plot showed that PHT was an excellent predictor of the manual HT interpretations (area under the curve = 0.973). Using a cutoff probability of 0.5 for the diagnosis of HI, we found that PHT had sensitivity, specificity, and accuracy of 100%, 90%, and 92.06%, respectively. The PHT has the potential to be substituted for manual interpretation of the HTT and to serve in a variety of clinical and research applications.
