Management and outcomes of breast cancer patients with radiotherapy interruption

Front Oncol. 2024 Jul 23;14:1337194. doi: 10.3389/fonc.2024.1337194. eCollection 2024.

ABSTRACT

BACKGROUND: Many cancer patients have not received timely treatment or even had treatment interruptions due to the COVID-19 pandemic. The objective of this investigation was to evaluate whether the prognosis of patients with breast cancer after surgery was affected by any interruptions in radiotherapy.

METHODS: The healthcare documents for breast cancer patients experiencing radiotherapy interruption after surgery, including treatment-related characteristics, and time of interruption, type of disease progression, and survival status, were collected between January and April 2020 during the Wuhan blockade.

RESULTS: The final number of patients included was 148, and neither the Kaplan-Meier (KM) survival curve nor the cross-tabulation analysis found statistical significance. Cox regression analysis also did not identify risk factors associated with PFS.

CONCLUSIONS: The prognosis of patients with postoperative breast cancer may not be significantly impacted by the interruption of radiotherapy, given its integration with additional treatments like targeted and endocrine therapies.

A DWI-based hypoxia model shows robustness in an external prostatectomy cohort

Front Oncol. 2024 Jul 23;14:1433197. doi: 10.3389/fonc.2024.1433197. eCollection 2024.

ABSTRACT

INTRODUCTION: Prostate cancer hypoxia is a negative prognostic biomarker. A promising MRI-based tool to assess hypoxia is the ‘Consumption and Supply based Hypoxia’ (CSH) model based on diffusion-weighted imaging (DWI). The aim of the study was to validate the association between the CSH hypoxia fraction (HFDWI) with pathological Grade Group (pGG) and pathological T-staging (pTstage) in an external prostatectomy cohort.

METHODS: Apparent diffusion coefficient (ADC) and fractional blood volume (fBV) maps were assessed from DWI data from 291 prostatectomies and combined by the CSH model. HFDWI was calculated for each lesion after median scaling of ADC and fBV to address differences in acquisition and analysis between centers. The absolute HFDWI values and the associations of HFDWI between pGG < 3 versus ≥ 3, and pTstage = 2 versus = 3 in the Netherlands Cancer Institute (NKI) cohort were compared to the obtained by original cohort (Oslo cohort). Statistical T- and Mann-Whitney tests (p<0.05) were performed. Pearson correlation was determined between HFDWI and individual pGG groups.

RESULTS: The HFDWI showed comparable absolute values and similar metric performance as in the original published cohort. Higher HFDWI values were observed for higher pGG (Oslo: 0.27; NKI: 0.24) compared to lower pGG (Oslo: 0.11; NKI: 0.17). Similar results were obtained for pTstage. Furthermore, HFDWI demonstrated a significant positive correlation with pGG groups 1-5 (ρ = 0.41, p<0.001).

CONCLUSION: The CSH model exhibited sufficient robustness in the external cohort, suggesting a plausible reflection of true hypoxia and enabling the use of the HFDWI metric for further research into prostate cancer and hypoxia.

Weekend Effect and Mortality Outcomes in Aortic Dissection: A Prospective Analysis

J Crit Care Med (Targu Mures). 2024 Apr 30;10(2):158-167. doi: 10.2478/jccm-2024-0014. eCollection 2024 Apr.

ABSTRACT

BACKGROUND: Aortic dissection (AD) is a critical heart condition with potentially severe outcomes. Our study aimed to investigate the existence of a “weekend effect” in AD by examining the correlation between patient outcomes and whether their treatment occurred on weekdays versus weekends.

METHODS: Specifically, we prospectively analysed the effect of weekday and weekend treatment on acute AD patient outcomes, both before surgical intervention and during hospitalization, for 124 patients treated from 2019-2021, as well as during 6 months of follow-up.

RESULTS: The mean age of the study population was 62.5 years, and patient age exhibited a high degree of variability. We recorded a mortality rate before surgery of 8.65% for the weekend group and 15% for the weekday group, but this difference was not statistically significant. During hospitalization, mortality was 50% in the weekend group and 25% in the weekday group, but this difference was not statistically significant. Discharge mortality was 9.61% in the weekend group and 5% in the weekday group.

CONCLUSIONS: Our findings suggest that there was no significant difference in mortality rates between patients admitted to the hospital on weekends versus weekdays. Therefore, the period of the week when a patient presents to the hospital with AD appears not to affect their mortality.

A Randomised Control Study Comparing Ultrasonography with Standard Clinical Methods in Assessing Endotracheal Tube Tip Positioning

J Crit Care Med (Targu Mures). 2024 Apr 30;10(2):177-182. doi: 10.2478/jccm-2024-0019. eCollection 2024 Apr.

ABSTRACT

INTRODUCTION: Airway ultrasound has been increasingly used in correct positioning of endotracheal tube. We hypothesize that a safe distance between endotracheal tube tip and carina can be achieved with the aid of ultrasound.

AIM OF THE STUDY: Our primary objective was to determine whether ultrasound guided visualisation of proximal end of endotracheal tube cuff is better when compared to conventional method in optimal positioning of tube tip. The secondary objective was to find the optimal endotracheal tube position at the level of incisors in adult Indian population.

MATERIALS AND METHODS: There were 25 patients each in the conventional group and the ultrasound group. Conventional method includes auscultation and end tidal capnography. In the ultrasound group the upper end of the endotracheal tube cuff was positioned with an intent to provide 4 cm distance from the tube tip to the carina. X ray was used in both groups for confirmation of tip position and comparison between the two groups. Further repositioning of the tube was done if indicated and the mean length of the tube at incisors was then measured.

RESULTS: After x ray confirmation, endotracheal tube repositioning was required in 24% of patients in the USG group and 40 % of patients in the conventional group. However, this result was not found to be statistically significant (p = 0.364). The endotracheal tube length at the level of teeth was 19.4 ± 1.35 cm among females and 20.95 ± 1.37 cm among males.

CONCLUSIONS: Ultrasonography is a reliable method to determine ETT position in the trachea. There was no statistically significant difference when compared to the conventional method. The average length of ETT at the level of incisors was 19.5 cm for females and 21 cm for males.

Higher Rates of Certain Autoimmune Diseases in Transgender and Gender Diverse Youth

Transgend Health. 2024 Jun 17;9(3):197-204. doi: 10.1089/trgh.2022.0079. eCollection 2024 Jun.

ABSTRACT

PURPOSE: The objective of this study is to determine the prevalence of certain autoimmune diseases in transgender and gender diverse (TGD) youth.

METHODS: A multicenter, retrospective analysis was conducted from January 2013 to January 2019 of youth ≤26 years of age with concurrent diagnoses of gender dysphoria (GD) and at least one of the studied autoimmune diseases. Prevalence rates were calculated and compared to previously reported rates. Statistical significance was determined using second generation p-values as pooled estimates of prevalence rates across study sites compared to a range of rates reported in the literature.

RESULTS: During the study period, 128 of 3812 (3.4%) youth evaluated for GD had a concurrent diagnosis of at least one of the studied autoimmune diseases. Three autoimmune diseases had prevalence rates significantly higher than those previously documented in the literature (second generation p-value=0.000): type 1 diabetes mellitus (112.8/10,000, 95% confidence interval [CI]: 83.8-151.8), systemic lupus erythematosus (13.1/10,000, 95% CI: 5.5-31.5), and Graves’ disease (12.3/10,000, 95% CI: 4.0-38.4).

CONCLUSION: There is an increased prevalence of certain autoimmune diseases in youth who identify as TGD presenting for subspecialty care. Limitations such as retrospective study design, selection bias, and reliance on electronic medical records make it difficult to draw wide-reaching conclusions about these findings. This study highlights the need for more research to delineate the impacts of unrecognized or untreated GD on autoimmune disease development and control.

Comparing Stigma and HIV Outcomes Between Transgender and Cisgender Women Sex Workers Living with HIV in the Dominican Republic

Transgend Health. 2024 Jun 17;9(3):232-240. doi: 10.1089/trgh.2022.0099. eCollection 2024 Jun.

ABSTRACT

PURPOSE: Using an intersectionality framework, we compared stigma and HIV care and treatment outcomes across transgender and cisgender women sex workers living with HIV in the Dominican Republic (DR).

METHODS: In 2018-2019, data were collected in Santo Domingo, DR, using interviewer-administered surveys among 211 cisgender women and 100 transgender women. We used t-tests and chi-square tests to examine differences in sex work stigma, HIV stigma, and HIV care and treatment.

RESULTS: Transgender participants reported more anticipated HIV stigma (mean=13.61, standard deviation [SD]=2.39) than cisgender participants (mean=12.96, SD=2.21; p=0.018), but there were no statistically significant differences for internalized or enacted HIV stigma. Cisgender participants reported more anticipated sex work stigma (cisgender: mean=50.00, SD=9.22; transgender: mean=44.02, SD=9.54; p<0.001), but transgender women reported more enacted (cisgender: mean=49.99, SD=9.11; transgender: mean=59.93, SD=4.89; p<0.001) and internalized sex work stigma (cisgender: mean=50.00, SD=8.80; transgender: mean=57.84, SD=8.34; p<0.001), with no significant differences in resistance to sex work stigma. Cisgender women were significantly more likely to have received HIV care (cisgender: 99.53%, transgender: 91.00%, p<0.001), be currently taking antiretroviral therapy (cisgender: 96.21%, transgender: 84.00%, p<0.001), and be virally suppressed (cisgender: 76.19%, transgender: 64.00%, p=0.025).

CONCLUSIONS: Transgender participants consistently had poorer HIV care and treatment outcomes compared with cisgender participants. Differences in stigma experiences between transgender and cisgender participants depended on the type of stigma. Findings reflect the intersectional nature of distinct types and forms of stigma among sex workers. Understanding the shared and unique experiences of transgender and cisgender women will improve HIV care engagement and viral suppression.

Evaluating the effectiveness of nicotine replacement therapy in critically ill smokers: A meta-analysis of randomized controlled trials

Tob Induc Dis. 2024 Aug 6;22. doi: 10.18332/tid/190798. eCollection 2024.

ABSTRACT

INTRODUCTION: The effectiveness of nicotine replacement therapy (NRT) in critically ill patients remains uncertain, as conflicting research results have been reported. Despite potential side effects and inconsistent data on safety and efficacy, NRT is still prescribed in intensive care units (ICUs) to prevent withdrawal symptoms and manage agitation in patients who are smokers. This meta-analysis aimed to assess the effectiveness of nicotine replacement therapy in critically ill smoking patients.

METHODS: A systematic review and meta-analysis of randomized controlled trials investigated the outcomes of smokers admitted to ICUs and were randomized either to receive or not receive nicotine replacement therapy (NRT) during their ICU stay. The MEDLINE and Embase databases were searched from inception through 13 February 2023 using OVID. The primary outcome was ICU length of stay (LOS) for this systematic review and meta-analysis. Meta-analysis was conducted using both random-effects and fixed-effect models; the latter is recommended when meta-analysis is restricted to just a few studies. The study was registered in the Prospective International Register of Systematic Reviews (PROSPERO) under reference number CRD42023407804.

RESULTS: Of 28 studies initially identified, three, with 67 patients on NRT and 72 controls, were deemed eligible for pooled analysis. Patients who received NRT experienced a shorter LOS (mean difference, MD= -3.06; 95% CI: -5.88 – -0.25, p=0.0, I2=0%). The mechanical ventilation (MV) duration was also shorter in the NRT group, but this difference was not statistically significant (MD= -1.24; 95% CI: -3.21-0.72, p=0.22, I2=12.69%). Delirium duration was reported by two studies, from which pooled analysis revealed an MD of -0.50 (95% CI: -1.63-0.62, I2=0%). The vasopressor duration was assessed in two studies, and the overall MD for vasopressor duration was not statistically different between NRT patients and controls in the fixed-effects model (MD=0.11; 95% CI: -0.75-0.96, I2=0%).

CONCLUSIONS: Critically ill smoker patients who received NRT experienced a significantly shorter ICU LOS but no significant differences in the durations of MV, vasopressor use, or delirium.

A prospective, randomized, controlled, double-blind, multi-center study to evaluate the efficacy and safety of a blue light device for the treatment of chronic back pain

Front Pain Res (Lausanne). 2024 Jul 23;5:1444401. doi: 10.3389/fpain.2024.1444401. eCollection 2024.

ABSTRACT

INTRODUCTION: Chronic back pain is one of the most prevalent conditions and has a large socio-economic impact. The lack of routine use of non-pharmacological options and issues associated with pharmacological treatments underscore high unmet needs in the treatment of back pain. Although blue light phototherapy has proven efficacy in dermatology, limited information is available about its use in back pain.

METHODS: In this proof-of-concept, randomized controlled trial, a pain relief patch (PRP) delivered blue light at the site of back pain for 30 min during five treatment sessions. The comparator device delivered green light for 5 s but was worn for 30 min. A follow-up visit took place after the last treatment. The primary objective was to demonstrate the superiority of treatment by PRP, compared to the control device, in reducing pain intensity at the end of the treatment period. The post-treatment visual analog scale (VAS) pain intensity score for each group was calculated across the five treatment sessions and compared to the baseline. Secondary objectives included the disability score (Roland-Morris Disability Questionnaire) and safety.

RESULTS: The full analysis set included 171 patients. A statistically significant reduction in pain intensity occurred after the use of PRP (p < 0.02), but the study did not meet its primary objective of a superiority trial aimed at demonstrating a 0.6 cm difference in favor of PRP on the VAS scale. There was no significant change in the disability scores. Subgroup analyses were performed to identify the treatment response by patient characteristics such as pain intensity at baseline and skin type. As expected, safety data showed erythema and skin discoloration in the PRP group but not in the control group.

DISCUSSION/CONCLUSION: This trial had multiple limitations that need to be addressed in future research. Although the primary objective was not achieved, this proof-of-concept study provides important efficacy and safety data in relation to the use of blue light in the treatment of chronic back pain and key insights that may support further research on similar devices.

Global epidemiology and species/genotype distribution of Cryptosporidium in camels: A systematic review and meta-analysis

Food Waterborne Parasitol. 2024 Jul 11;36:e00235. doi: 10.1016/j.fawpar.2024.e00235. eCollection 2024 Sep.

ABSTRACT

This review analyzed reported data of Cryptosporidium prevalence in camels and the species/genotype distribution. Four databases (PubMed, Web of Science, Scopus, Google Scholar) were screened, and studies published by April 1, 2024, were included. Total estimates and 95% CIs were calculated using a random-effects model. The weighted prevalence of Cryptosporidium spp. in 7372 camels examined from 12 different countries was estimated at 13.8% with a 95% CI of 10.3-18.4%. The sensitivity analysis based on excluding the individual studies did not result in significant statistical changes in the final weighted prevalence. Subgroup prevalence of Cryptosporidium spp. in camels was analyzed by publication year, continent, WHO region, country, camel type, sample size, diagnostic method, age, and gender. A significant publication bias (P < 0.05) was reported in the present study. Limitations encountered in this study encompassed: insufficient study diversity, reliance on single study results, inadequate molecular and serological studies in comparison to microscopic studies, etc., all of which could impact the findings. The study identified eight Cryptosporidium spp. in camels: C. parvum, C. andersoni, C. bovis, C. muris, C. ratti, C. occultus, C. ubiquitum, and C. hominis. The first three species had pooled prevalence rates of 65.5%, 66%, and 19.2%, respectively. Each of the remaining five species was documented using a single dataset/study. Moreover, genotypes IIdA19G1, IIaA15G1R1, If-like-A15G2, IIdA15G1, IIaA15G2R1, IIaA17G2R1, and IIaA18G2R1 (C. parvum), genotype IV (C. ratti), genotype XIIa (C. ubiquitum), and genotype IkA19G1 (C. hominis) have been identified in camels globally. The findings suggest that camels can act as a source of infection for a variety of Cryptosporidium species/genotypes, and can therefore play a key role in disseminating this protozoan to humans and animals.

Beyond air pollution: a national assessment of cooking-related burns in Ghana

Inj Prev. 2024 Aug 6:ip-2023-045191. doi: 10.1136/ip-2023-045191. Online ahead of print.

ABSTRACT

INTRODUCTION: Household energy transitions have the potential to reduce the burden of several health outcomes but have narrowly focused on those mediated by reduced exposure to air pollution, despite concerns about the burden of injury outcomes. Here, we aimed to describe the country-level incidence of severe cooking-related burns in Ghana and identify household-level risk factors for adults and children.

METHODS: We conducted a national household energy use survey including 7389 households across 370 enumeration areas in Ghana in 2020. In each household, a pretested version of the Clean Cooking Alliance Burns Surveillance Module was administered to the primary cook. We computed incidence rates of severe cooking-related burns and conducted bivariate logistic regression to identify potential risk factors.

RESULTS: We documented 129 severe cooking-related burns that had occurred in the previous year. The incidence rate (95% CI) of cooking-related burns among working-age females was 17 (13 to 21) per 1000 person-years or 8.5 times higher than that of working-age males. Among adults, the odds of experiencing a cooking-related burn were 2.29 (95% CI 1.02 to 5.14) and 2.40 (95% CI 1.04 to 5.55) times higher among primary wood and charcoal users respectively compared with primary liquified petroleum gas users. No child burns were documented in households where liquified petroleum gas was primarily used.

CONCLUSION: Using a nationally representative sample, we found that solid fuel use doubled the odds of cooking-related burns compared with liquified petroleum gas. Ghana’s efforts to expand access to liquified petroleum gas should focus on safe use.
