Cropsi study: Efficacy and safety of cryotherapy and cryocompression in the prevention of chemotherapy-induced peripheral neuropathy in patients with breast and gynecological cancer-A prospective, randomized trial.
OBJECTIVE
This study aimed to demonstrate the superiority of cryocompression over cryotherapy alone in the prevention of chemotherapy-induced peripheral neuropathy (CIPN) grade 2 or above.
METHODS
This prospective randomized study was conducted between May 2020 and January 2023 in Innsbruck. Eligible patients had a diagnosis of gynecological cancer and received a minimum of 3 cycles of taxane-based CT (neoadjuvant, adjuvant or palliative therapy). Patients were randomized 1:1 to receive either cryotherapy or cryocompression on their upper extremities during chemotherapy (CT). We performed temperature measurements, two QoL questionnaires and neurological tests during CT and at follow-up 3 and 6-9 months after the completion of CT. CIPN was assessed using the CTCAE score.
RESULTS
Of 200 patients recruited, both groups showed a lower prevalence of CIPN in this study compared to recent literature. In the group receiving cryotherapy, the prevalence of grade 1 CIPN was 30.1 %, and that of grade 2 CIPN or above was 13.7 %; in the group treated with cryocompression, the prevalence of grade 1 CIPN was 32.8 %, and that of grade 2 or above CIPN was 17.2 %. We found a significant reduction in temperature in the cryotherapy and cryocompression groups. Regarding the two QOL questionnaires as well as the neurological tests no significant differences were found between the two groups.
CONCLUSION
Our study suggests that cryotherapy as well as cryocompression is a safe and effective way to cool patients' extremities to lower the prevalence of CIPN. Cryocompression was not more effective than cryotherapy alone in the prevention of CIPN.

In cancer research, circulating tumor cells (CTCs) were identified as the main drivers of metastasis. They are vital for early detection and prevention of metastasis during cancer treatment. Even though continuous progress in research offers more and more tools to combat cancer, we still lack a proper arsenal of therapeutics. Especially in tumors with close to no targeting options, like triple-negative breast cancer, early detection is often the main difference between successful and failed therapy. When such tumors are detected too late, they may have already produced plenty of CTCs, likely causing metastasis, which is the primary reason for tumor-associated deaths. Detecting those CTCs early on could substantially impact therapy outcomes and the 5-year survival rate. In our study, we developed and evaluated a reliable and affordable CTC screening method based on flow cytometry and 5-aminolevulinic acid (5-ALA) staining. We successfully established a circulation model for 5-ALA and CTCs research and demonstrated that the method can detect an average of 11 ± 3.3 CTCs out of 10,000 peripheral blood mononuclear cells, representing as low as approximately 0.1 % with a reasonable number of false positive events. Additionally, we present initial results on a theranostic approach using 5-ALA converted to protoporphyrin IX. The outcomes of this study might contribute significantly to the further development of CTC detection and the overall detection and treatment of cancer.

OBJECTIVE
An association between blunt head trauma and cerebral venous sinus thrombosis (CVST) has been recognized, but its symptoms are nonspecific and the duration of symptoms remains unclear. Anticoagulation therapy is not considered necessary in most cases of traumatic CVST; however, this is controversial. The aim of this study was to describe the clinical characteristics and outcomes of children with CVST after isolated head trauma.
METHODS
The records of pediatric patients with isolated head trauma admitted for observation at 3 medical centers between January 2018 and May 2023 were reviewed retrospectively. CVST was diagnosed on MR venography (MRV). Clinical presentation, therapeutic management, and outcomes were evaluated in patients who had follow-up MRV.
RESULTS
Of 260 pediatric patients with head trauma admitted to the 3 hospitals, 26 patients underwent MRV and 8 (30.8%) were diagnosed with CVST. One patient was treated with heparin, while the others received conservative treatment. All patients were discharged home asymptomatic. MRV performed during follow-up displayed complete recanalization in all cases, except for 1 case with partial recanalization. The median hospital stay was longer in patients with CVST than in those without CVST (9.5 vs 3.0 days, p = 0.001).
CONCLUSIONS
The length of stay of pediatric patients with traumatic CVST was prolonged compared with those without CVST, but most patients had good outcomes with spontaneous recanalization following conservative treatment.

Chronic kidney disease (CKD) has severe consequences on the quality and expectancy of life and is considered a major health problem worldwide. This is, especially relevant in pediatric patients, as they have unique characteristics and a mortality rate 30 times higher (in advanced stages) than healthy people. This review aims to define the minimum components for the diagnostic approach and monitoring of CKD in the pediatric population from primary health care to promote comprehensive care and adequate risk management. For this purpose, we performed a systematic review of the literature with a panel of experts. Based on the evidence, to optimize the definition, diagnosis, and timely treatment of CKD in the pediatric population, we formulated 21 recommendations. These were approved by the research team and peer-reviewed by clinical experts. They will facilitate the definition of the diagnostic approach for CKD in the pediatric population in primary health-care settings, allowing for timely treatment intervention, comprehensive care, and monitoring of this disease.

OBJECTIVE
The objective of this study was to assess the safety and accuracy of ChatGPT recommendations in comparison to the evidence-based guidelines from the North American Spine Society (NASS) for the diagnosis and treatment of cervical radiculopathy.
METHODS
ChatGPT was prompted with questions from the 2011 NASS clinical guidelines for cervical radiculopathy and evaluated for concordance. Selected key phrases within the NASS guidelines were identified. Completeness was measured as the number of overlapping key phrases between ChatGPT responses and NASS guidelines divided by the total number of key phrases. A senior spine surgeon evaluated the ChatGPT responses for safety and accuracy. ChatGPT responses were further evaluated on their readability, similarity, and consistency. Flesch Reading Ease scores and Flesch-Kincaid reading levels were measured to assess readability. The Jaccard Similarity Index was used to assess agreement between ChatGPT responses and NASS clinical guidelines.
RESULTS
A total of 100 key phrases were identified across 14 NASS clinical guidelines. The mean completeness of ChatGPT-4 was 46%. ChatGPT-3.5 yielded a completeness of 34%. ChatGPT-4 outperformed ChatGPT-3.5 by a margin of 12%. ChatGPT-4.0 outputs had a mean Flesch reading score of 15.24, which is very difficult to read, requiring a college graduate education to understand. ChatGPT-3.5 outputs had a lower mean Flesch reading score of 8.73, indicating that they are even more difficult to read and require a professional education level to do so. However, both versions of ChatGPT were more accessible than NASS guidelines, which had a mean Flesch reading score of 4.58. Furthermore, with NASS guidelines as a reference, ChatGPT-3.5 registered a mean ± SD Jaccard Similarity Index score of 0.20 ± 0.078 while ChatGPT-4 had a mean of 0.18 ± 0.068. Based on physician evaluation, outputs from ChatGPT-3.5 and ChatGPT-4.0 were safe 100% of the time. Thirteen of 14 (92.8%) ChatGPT-3.5 responses and 14 of 14 (100%) ChatGPT-4.0 responses were in agreement with current best clinical practices for cervical radiculopathy according to a senior spine surgeon.
CONCLUSIONS
ChatGPT models were able to provide safe and accurate but incomplete responses to NASS clinical guideline questions about cervical radiculopathy. Although the authors' results suggest that improvements are required before ChatGPT can be reliably deployed in a clinical setting, future versions of the LLM hold promise as an updated reference for guidelines on cervical radiculopathy. Future versions must prioritize accessibility and comprehensibility for a diverse audience.

BACKGROUND
HIV-infected children have a higher risk of presenting infections, including the hepatitis A virus (HAV). The inactivated HAV vaccine is immunogenic in immunocompetent hosts; however, there are insufficient studies on the duration of seroprotection in HIV-infected children.
METHODS
An analytical cohort study was conducted. HIV-1-infected children who received the inactivated HAV vaccine (2 doses) were included. Blood samples were taken for antibody measurement, the first one 28 days after the second dose and another 7 years after the vaccination schedule. Information on viral load, immunological category, weight, height, and response to antiretroviral treatment from diagnosis to the last assessment was obtained.
RESULTS
19 patients were included, with a mean age of 12.6 years (SD ± 2.29). 58% were male. 80% of the patients presented protective immunoglobulin G antibodies against HAV 7-year post-vaccination. The antibody concentration was found to be between 13 and 80 mIU/mL (median of 80 mIU/mL). 52% showed some degree of immunosuppression. There was no statistically significant relationship between the presence of seroprotection and viral load, treatment failure, immunological category, and malnutrition. Twelve patients presented with antiretroviral treatment failure, and in 33% of them, the antibodies did not offer satisfactory seroprotection.
CONCLUSION
7-year post-vaccination, 80% of HIV-infected children maintain seroprotection titers against HAV.

BACKGROUND
The worldwide prevalence of arterial hypertension in pediatric patients is 3.5%, and it has repercussions at renal, cardiovascular, neurological, and lifestyle levels. This study aimed to estimate the prevalence of arterial hypertension, mortality, and follow-up in patients with acute renal failure in the nephrology outpatient clinic at a second-level hospital in Northwestern Mexico.
METHODS
We conducted a descriptive, retrospective, and observational study. Men and women aged 1-18 years diagnosed with acute kidney injury were analyzed from January 1, 2012, to December 31, 2021. The medical and electronic records of the candidate patients were analyzed, and nutritional data, laboratory analysis, most frequent etiology, and follow-up in the pediatric nephrology clinic were collected. Those with exacerbated chronic kidney disease and previous diagnosis of high blood pressure were excluded.
RESULTS
One hundred and seventy-four patients were evaluated, and only 40 were eligible for the study (22.98%), predominantly males with a mean age of 9.9 years. The degree of arterial hypertension was 50% for grade I and 50% for grade II (p = 0.007); the mortality rate was 32%. One hundred percent of hypertension cases were controlled at 6 months after discharge (p = 0.000080).
CONCLUSIONS
Our results were similar to those reported in other studies. Follow-up and early detection of arterial hypertension in children need to be strengthened.

BACKGROUND
Globally, over 39% of individuals are obese. Metabolic syndrome, usually accompanied by obesity, is regarded as a major contributor to noncommunicable diseases. Given this relationship, the concepts of metabolically healthy and unhealthy obesity, considering metabolic status, have been evolving. Attention is being directed to metabolically healthy people with obesity who have relatively low transition rates to noncommunicable diseases. As obesity rates continue to rise and unhealthy behaviors prevail among young adults, there is a growing need for obesity management that considers these metabolic statuses. A nomogram can be used as an effective tool to predict the risk of transitioning to metabolically unhealthy obesity from a metabolically healthy status.
OBJECTIVE
The study aimed to identify demographic factors, health behaviors, and 5 metabolic statuses related to the transition from metabolically healthy obesity to unhealthy obesity among people aged between 20 and 44 years and to develop a screening tool to predict this transition.
METHODS
This secondary analysis study used national health data from the National Health Insurance System in South Korea. We analyzed the customized data using SAS (SAS Institute Inc) and conducted logistic regression to identify factors related to the transition from metabolically healthy to unhealthy obesity. A nomogram was developed to predict the transition using the identified factors.
RESULTS
Among 3,351,989 people, there was a significant association between the transition from metabolically healthy to unhealthy obesity and general characteristics, health behaviors, and metabolic components. Male participants showed a 1.30 higher odds ratio for transitioning to metabolically unhealthy obesity than female participants, and people in the lowest economic status were also at risk for the transition (odds ratio 1.08, 95% CI 1.05-1.1). Smoking status, consuming >30 g of alcohol, and insufficient regular exercise were negatively associated with the transition. Each relevant variable was assigned a point value. When the nomogram total points reached 295, the shift from metabolically healthy to unhealthy obesity had a prediction rate of >50%.
CONCLUSIONS
This study identified key factors for young adults transitioning from healthy to unhealthy obesity, creating a predictive nomogram. This nomogram, including triglycerides, waist circumference, high-density lipoprotein-cholesterol, blood pressure, and fasting glucose, allows easy assessment of obesity risk even for the general population. This tool simplifies predictions amid rising obesity rates and interventions.

Randomized Controlled Trial
BACKGROUND
Hypertension is one of the most important cardiovascular disease risk factors and affects >100 million American adults. Hypertension-related health inequities are abundant in Black communities as Black individuals are more likely to use the emergency department (ED) for chronic disease-related ambulatory care, which is strongly linked to lower blood pressure (BP) control, diminished awareness of hypertension, and adverse cardiovascular events. To reduce hypertension-related health disparities, we developed MI-BP, a culturally tailored multibehavior mobile health intervention that targeted behaviors of BP self-monitoring, physical activity, sodium intake, and medication adherence in Black individuals with uncontrolled hypertension recruited from ED and community-based settings.
OBJECTIVE
We sought to determine the effect of MI-BP on BP as well as secondary outcomes of physical activity, sodium intake, medication adherence, and BP control compared to enhanced usual care control at 1-year follow-up.
METHODS
We conducted a 1-year, 2-group randomized controlled trial of the MI-BP intervention compared to an enhanced usual care control group where participants aged 25 to 70 years received a BP cuff and hypertension-related educational materials. Participants were recruited from EDs and other community-based settings in Detroit, Michigan, where they were screened for initial eligibility and enrolled. Baseline data collection and randomization occurred approximately 2 and 4 weeks after enrollment to ensure that participants had uncontrolled hypertension and were willing to take part. Data collection visits occurred at 13, 26, 39, and 52 weeks. Outcomes of interest included BP (primary outcome) and physical activity, sodium intake, medication adherence, and BP control (secondary outcomes).
RESULTS
We obtained consent from and enrolled 869 participants in this study yet ultimately randomized 162 (18.6%) participants. At 1 year, compared to the baseline, both groups showed significant decreases in systolic BP (MI-BP group: 22.5 mm Hg decrease in average systolic BP and P<.001; control group: 24.1 mm Hg decrease and P<.001) adjusted for age and sex, with no significant differences between the groups (time-by-arm interaction: P=.99). Similar patterns where improvements were noted in both groups yet no differences were found between the groups were observed for diastolic BP, physical activity, sodium intake, medication adherence, and BP control. Large dropout rates were observed in both groups (approximately 60%).
CONCLUSIONS
Overall, participants randomized to both the enhanced usual care control and MI-BP conditions experienced significant improvements in BP and other outcomes; however, differences between groups were not detected, speaking to the general benefit of proactive outreach and engagement focused on cardiometabolic risk reduction in urban-dwelling, low-socioeconomic-status Black populations. High dropout rates were found and are likely to be expected when working with similar populations. Future work is needed to better understand engagement with mobile health interventions, particularly in this population.

Assessment of the Feasibility of Objective Parameters as Primary End Points for Patients Affected by Knee Osteoarthritis: Protocol for a Pilot, Open Noncontrolled Trial (:SMILE:).
BACKGROUND
Osteoarthritis (OA) is a disabling condition that affects more than one-third of people older than 65 years. Currently, 80% of these patients report movement limitations, 20% are unable to perform major activities of daily living, and approximately 11% require personal care. In 2014, the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) recommended, as the first step in the pharmacological treatment of knee osteoarthritis, a background therapy with chronic symptomatic slow-acting osteoarthritic drugs such as glucosamine sulfate, chondroitin sulfate, and hyaluronic acid. The latter has been extensively evaluated in clinical trials as intra-articular and oral administration. Recent reviews have shown that studies on oral hyaluronic acid generally measure symptoms using only subjective parameters, such as visual analog scales or quality of life questionnaires. As a result, objective measures are lacking, and data validity is generally impaired.
OBJECTIVE
The main goal of this pilot study with oral hyaluronic acid is to evaluate the feasibility of using objective tools as outcomes to evaluate improvements in knee mobility. We propose ultrasound and range of motion measurements with a goniometer that could objectively correlate changes in joint mobility with pain reduction, as assessed by the visual analog scale. The secondary objective is to collect data to estimate the time and budget for the main double-blind study randomized trial. These data may be quantitative (such as enrollment rate per month, number of screening failures, and new potential outcomes) and qualitative (such as site logistical issues, patient reluctance to enroll, and interpersonal difficulties for investigators).
METHODS
This open-label pilot and feasibility study is conducted in an orthopedic clinic (Timisoara, Romania). The study includes male and female participants, aged 50-70 years, who have been diagnosed with symptomatic knee OA and have experienced mild joint discomfort for at least 6 months. Eight patients must be enrolled and treated with Syalox 300 Plus (River Pharma) for 8 weeks. It is a dietary supplement containing high-molecular-weight hyaluronic acid, which has already been marketed in several European countries. Assessments are made at the baseline and final visits.
RESULTS
Recruitment and treatment of the 8 patients began on February 15, 2018, and was completed on May 25, 2018. Data analysis was planned to be completed by the end of 2018. The study was funded in February 2019. We expect the results to be published in a peer-reviewed clinical journal in the last quarter of 2024.
CONCLUSIONS
The data from this pilot study will be used to assess the feasibility of a future randomized clinical trial in OA. In particular, the planned outcomes (eg, ultrasound and range of motion), safety, and quantitative and qualitative data must be evaluated to estimate in advance the time and budget required for the future main study. Finally, the pilot study should provide preliminary information on the efficacy of the investigational product.
