The impact of metronidazole on pain persistence after fertility-sparing endometriosis surgery: METROFERT randomized study

Recent studies have shown that a disrupted microbiome is associated with endometriosis. Despite endometriosis affecting 1 in 10 reproductive-aged women, there is a lack of innovative and nonhormonal long-term effective treatments. Studies have reported an approximately 20% to 37.5% persistence of pain after fertility-sparing endometriosis surgery. Metronidazole has been shown to decrease inflammatory markers and the size of endometriosis lesions in animal studies. To determine if modulating the microbiome with oral metronidazole for 14days after fertility-sparing endometriosis surgery decreases pain persistence postoperatively. This was a randomized, multicenter, placebo-controlled, double-blind trial. Individuals 18 to 50years old were prospectively randomized to placebo vs oral metronidazole for 14days immediately after endometriosis fertility-sparing excision surgery. The primary outcome was binary, subjective pain persistence at 6weeks postoperatively. Secondary outcomes included quality of life, sexual function, and endometriosis-associated pain scores according to the Endometriosis Health Profile-5, Female Sexual Function Index, and a visual analog scale. One hundred fifty-two participants were approached from October 2020 to October 2023 to enroll in the study. Sixty-four participants were excluded either because they did not meet inclusion or exclusion criteria or because they declined to participate. Eighty-eight participants were randomized in a 1:1 ratio to receive either the oral placebo or metronidazole after endometriosis excision surgery; 18.2% of participants were lost to follow-up or discontinued treatment and this was not significantly different between the 2 arms, yielding a final cohort of 72 participants. Baseline demographics of the 2 study groups were similar. There was no statistically significant improvement in the primary outcome of binary subjective pain persistence between the metronidazole group compared to placebo (84% vs 88%, P=.74) at 6weeks postoperatively. Further, no significant differences between treatments were detected in the secondary outcomes. A postoperative 14-day regimen of oral metronidazole immediately after fertility-sparing endometriosis surgery was not associated with any significant differences between treatment groups in the persistence of endometriosis-related pain symptoms compared to placebo at 6weeks.

Ovarian microenvironment: challenges and opportunities in protecting against chemotherapy-associated ovarian damage.

Chemotherapy-associated ovarian damage (CAOD) is one of the most feared short- and long-term side effects of anticancer treatment in premenopausal women. Accumulating detailed data show that different chemotherapy regimens can lead to disturbance of ovarian hormone levels, reduced or lost fertility, and an increased risk of early menopause. Previous studies have often focused on the direct effects of chemotherapeutic drugs on ovarian follicles, such as direct DNA damage-mediated apoptotic death and primordial follicle burnout. Emerging evidence has revealed an imbalance in the ovarian microenvironment during chemotherapy. The ovarian microenvironment provides nutritional support and transportation of signals that stimulate the growth and development of follicles, ovulation, and corpus luteum formation. The close interaction between the ovarian microenvironment and follicles can determine ovarian function. Therefore, designing novel and precise strategies to manipulate the ovarian microenvironment may be a new strategy to protect ovarian function during chemotherapy. This review details the changes that occur in the ovarian microenvironment during chemotherapy and emphasizes the importance of developing new therapeutics that protect ovarian function by targeting the ovarian microenvironment during chemotherapy. A comprehensive review of the literature was performed by searching PubMed up to April 2024. Search terms included 'ovarian microenvironment' (ovarian extracellular matrix, ovarian stromal cells, ovarian interstitial, ovarian blood vessels, ovarian lymphatic vessels, ovarian macrophages, ovarian lymphocytes, ovarian immune cytokines, ovarian oxidative stress, ovarian reactive oxygen species, ovarian senescence cells, ovarian senescence-associated secretory phenotypes, ovarian oogonial stem cells, ovarian stem cells), terms related to ovarian function (reproductive health, fertility, infertility, fecundity, ovarian reserve, ovarian function, menopause, decreased ovarian reserve, premature ovarian insufficiency/failure), and terms related to chemotherapy (cyclophosphamide, lfosfamide, chlormethine, chlorambucil, busulfan, melphalan, procarbazine, cisplatin, doxorubicin, carboplatin, taxane, paclitaxel, docetaxel, 5-fluorouraci, vincristine, methotrexate, dactinomycin, bleomycin, mercaptopurine). The ovarian microenvironment shows great changes during chemotherapy, inducing extracellular matrix deposition and stromal fibrosis, angiogenesis disorders, immune microenvironment disturbance, oxidative stress imbalances, ovarian stem cell exhaustion, and cell senescence, thereby lowering the quantity and quality of ovarian follicles. Several methods targeting the ovarian microenvironment have been adopted to prevent and treat CAOD, such as stem cell therapy and the use of free radical scavengers, senolytherapies, immunomodulators, and proangiogenic factors. Ovarian function is determined by its 'seeds' (follicles) and 'soil' (ovarian microenvironment). The ovarian microenvironment has been reported to play a vital role in CAOD and targeting the ovarian microenvironment may present potential therapeutic approaches for CAOD. However, the relation between the ovarian microenvironment, its regulatory networks, and CAOD needs to be further studied. A better understanding of these issues could be helpful in explaining the pathogenesis of CAOD and creating innovative strategies for counteracting the effects exerted on ovarian function. Our aim is that this narrative review of CAOD will stimulate more research in this important field. Not applicable.

European randomized controlled trial evaluating differential target multiplexed spinal cord stimulation and conventional medical management in subjects with persistent back pain ineligible for spine surgery: 24-month results.

Differential target multiplexed spinal cord stimulation (DTM SCS) was shown to be superior to conventional SCS for treating chronic low back pain (CLBP) in subjects with persistent spinal pain syndrome with previous spinal surgery (PSPS-T2) or ineligible for it (PSPS-T1). This study reports 24-month efficacy and safety of DTM SCS vs. conventional medical management (CMM) in PSPS-T1 subjects across four European countries. This is a prospective, multicenter, open-label, randomized, controlled trial with optional crossover. Subjects randomized 1:1 to DTM SCS or CMM. Primary endpoint was responder rate (% subjects reporting ≥50% CLBP relief) at 6 months. A superiority test compared responder rates between treatments. CLBP and leg pain levels, functional disability, quality of life (QoL), patient satisfaction and global impression of change were evaluated for 24 months. A Composite Responder Index (CRI) was obtained using CLBP relief, disability and QoL. Incidence of study-related adverse events evaluated safety. A total of 55 and 57 subjects were randomized to DTM SCS and CMM respectively. DTM SCS was superior, with CLBP responder rates ≥80% and CLBP relief >5.6 cm (>70% reduction) through the 24-month follow-up. Improvements with DTM SCS in other outcomes were sustained. The CRI was >80% for DTM SCS through 24 months. Opioid medication intake decreased in subjects treated with DTM SCS. Most patients treated with DTM SCS felt satisfied and improved at the end of the study. Safety was congruent with other studies. DTM SCS is efficacious and safe during 24 months for the treatment of CLBP and leg pain in PSPS-T1 patients ineligible for spine surgery. This randomized controlled trial shows that Differential Target Multiplexed SCS (DTM SCS) is an effective and safe long-term treatment for PSPS type 1 patients suffering from axial low back pain with or without leg pain and who are ineligible for spinal surgery. Currently, CMM treatments are their only option and provide limited benefits. Besides superior pain relief, DTM SCS provides significant improvements in functional disability, quality of life, high levels of satisfaction and perceived impression of change.

Emotions in search of words: Does alexithymia predict treatment outcome in chronic musculoskeletal pain?

Chronic pain, with its complex and multidimensional nature, poses significant challenges in identifying effective long-term treatments. There is growing scientific interest in how psychopathological and personality dimensions may influence the maintenance and development of chronic pain. This longitudinal study aimed to investigate whether alexithymia can predict the improvement of pain severity following a treatment-as-usual programme for chronic musculoskeletal pain over and above psychological cofactors (emotional distress, catastrophizing, and self-efficacy). A consecutive sample of 129 patients with diagnosed chronic musculoskeletal pain referred to two tertiary care centres was recruited and treated for 16weeks. Clinical pain, psychological distress, self-efficacy, catastrophizing, and alexithymia were assessed with validated self-report measures at the first medical visit (T0) and at 16-week follow-up (T1). Compared with non-responder patients (n=72, 55.8%), those who responded (i.e., reduction of >30% in pain severity; n=57, 44.2%) reported an overall improvement in psychological variables except alexithymia. Alexithymia showed relative stability between baseline and follow-up within the entire sample and remained a significant predictor of treatment outcome even when other predictive cofactors (i.e., pain interference, depressive symptoms, and catastrophizing) were considered simultaneously. Our results suggest that identifying patients with a co-occurrence between alexithymia, depressive symptoms, catastrophizing, and the stressful experience of chronic pain can be clinically relevant in pain prevention and intervention programs.

A meta-analysis of randomized controlled clinical trials for implications of acute treatment effects on glomerular filtration rate for long-term kidney protection

Pharmacologic interventions to slow chronic kidney disease progression, such as ACE-inhibitors, angiotensin receptor blockers, or sodium glucose co-transporter 2 inhibitors, often produce acute treatment effects on glomerular filtration rate (GFR) that differ from their long-term chronic treatment effects. Observational studies assessing the implications of acute effects cannot distinguish acute effects from GFR changes unrelated to the treatment. Here, we performed meta-regression analysis of multiple trials to isolate acute effects to determine their long-term implications. In 64 randomized controlled trials (RCTs), enrolling 154,045 participants, we estimated acute effects as the mean between-group difference in GFR slope from baseline to three months, effects on chronic GFR slope (starting at three months after randomization), and effects on three composite kidney endpoints defined by kidney failure (GFR 15 ml/min/1.73m2 or less, chronic dialysis, or kidney transplantation) or sustained GFR declines of 30%, 40% or 57% decline, respectively. We used Bayesian meta-regression to relate acute effects with treatment effects on chronic slope and the composite kidney endpoints. Overall, acute effects were not associated with treatment effects on chronic slope. Acute effects were associated with the treatment effects on composite kidney outcomes such that larger negative acute effects were associated with lesser beneficial effects on the composite kidney endpoints. Associations were stronger when the kidney composite endpoints were defined by smaller thresholds of GFR decline (30% or 40%). Results were similar in a subgroup of interventions with supposedly hemodynamic effects that acutely reduce GFR. For studies with GFR 60 mL/min/1.73m2 or under, negative acute effects were associated with larger beneficial effects on chronic GFR slope. Thus, our data from a large and diverse set of RCTs suggests that acute effects of interventions may influence the treatment effect on clinical kidney outcomes.

GCT-01. CENTRAL NERVOUS SYSTEM GERM CELL TUMORS – GENERATING A CONSENSUS IN THEIR DIAGNOSIS AND MANAGEMENT

Abstract BACKGROUND Despite the excellent outcomes of central nervous system (CNS) germ cell tumors (GCTs), there still exists significant differences in how GCTs are diagnosed and managed in different parts of the world. Additionally, the long-term toxicities and morbidities of the current therapies, and their substantial negative impact on the social wellbeing of our patients should clearly indicate that the current achievements are not enough. Further, important molecular data have emerged over the past decade that we have not witnessed their translation into any of the ongoing clinical trials. METHODS A comprehensive review of all major CNS GCT clinical trials will be discussed, in addition to a detailed review of the several issues of debate. Moreover, the latest developments in molecular landscape of GCTs will be provided in order to identify the hurdles that affect their incorporation in GCT clinical trials. RESULTS Tumor marker cut-offs that differentiate between germinoma and non-germinomatous germ cell tumors are clearly different between the various groups around the world. Additionally, differences exist in the chemotherapy backbones, radiation therapy field and dose, and the appropriate regimens to treat some of the rarer GCTs. Furthermore, there is no clear guideline on how to treat patients who do not achieve complete response after chemotherapy. CONCLUSIONS Discussing the clear differences that exist in the diagnosis and management of CNS GCTs is a critical first step in generating a clear consensus between the North American, European, Asian, and Latin American groups, which will certainly guide future clinical trials, improve the outcomes as well as the long-term treatment effects for this group of patients.

Molecular-targeted therapy for childhood low-grade glial and glioneuronal tumors.

Since the discovery of the association between BRAF mutations and fusions in the development of childhood low-grade gliomas and the subsequent recognition that most childhood low-grade glial and glioneuronal tumors have aberrant signaling through the RAS/RAF/MAP kinase pathway, there has been a dramatic change in how these tumors are conceptualized. Many of the fusions and mutations present in these tumors are associated with molecular targets, which have agents in development or already in clinical use. Various agents, including MEK inhibitors, BRAF inhibitors, MTOR inhibitors and, in small subsets of patients NTRK inhibitors, have been used successfully to treat children with recurrent disease, after failure of conventional approaches such as surgery or chemotherapy. The relative benefits of chemotherapy as compared to molecular-targeted therapy for children with newly diagnosed gliomas and neuroglial tumors are under study. Already the combination of an MEK inhibitor and a BRAF inhibitor has been shown superior to conventional chemotherapy (carboplatin and vincristine) in newly diagnosed children with BRAF-V600E mutated low-grade gliomas and neuroglial tumors. However, the long-term effects of such molecular-targeted treatment are unknown. The potential use of molecular-targeted therapy in early treatment has made it mandatory that the molecular make-up of the majority of low-grade glial and glioneuronal tumors is known before initiation of therapy. The primary exception to this rule is in children with neurofibromatosis type 1 who, by definition, have NF1 loss; however, even in this population, gliomas arising in late childhood and adolescence or those not responding to conventional treatment may be candidates for biopsy, especially before entry on molecular-targeted therapy trials.

The long-term effect of bariatric/metabolic surgery versus pharmacologic therapy in type 2 diabetes mellitus patients: A systematic review and meta-analysis.

Metabolic/bariatric surgery as a treatment for obesity and related diseases, such as type 2 diabetes mellitus (T2DM), has been increasingly recognised in recent years. However, compared with conventional pharmacologic therapy, the long-term effect (≥ 5years) of metabolic surgery in T2DM patients is still unclear. This study aimed to evaluate the diabetes remission rate, incidence of diabetic microvascular complications, incidence of macrovascular complications, and mortality in T2DM patients who received metabolic surgery versus pharmacologic therapy more than 5years after the surgery. Searching the database, including PubMed, Embase, Web of Science, and Cochrane Library from the inception to recent (2024), for randomised clinical trials (RCTs) or cohort studies comparing T2DM patients treated with metabolic surgery versus pharmacologic therapy reporting on the outcomes of the diabetes remission rate, diabetic microvascular complications, macrovascular complications, or mortality over 5years or more. A total of 15 articles with a total of 85,473 patients with T2DM were eligible for review and meta-analysis in this study. There is a significant long-term increase in diabetes remission for metabolic surgery compared with conventional medical therapy in the overall pooled estimation and RCT studies or cohort studies separately (overall: OR=4.58, 95% CI: 1.89-11.07, P<0.001). Significant long-term decreases were found in the pooled results of microvascular complications incidence (HR=0.57, 95% CI: 0.41-0.78, P<0.001), macrovascular complications incidence (HR=0.59, 95% CI: 0.50-0.70, P<0.001) and mortality (HR=0.53, 95% CI: 0.53-0.79, P=0.0018). Metabolic surgery showed more significant long-term effects than pharmacologic therapy on diabetes remission, macrovascular complications, microvascular complications incidence, and all-cause mortality in patients with T2DM using currently available evidence. More high-quality evidence is needed to validate the long-term effects of metabolic surgery versus conventional treatment in diabetes management.

CD4 nadir and neurocognitive trajectories in people living with HIV.

Human immunodeficiency virus-associated neurocognitive disorders persist in the combination antiretroviral therapy era. CD4 nadir is a well-established predictor of cognition cross-sectionally, but its impact on longitudinal neurocognitive (NC) trajectories is unclear. The few studies on this topic examined trajectories of global cognition, rather than specific NC domains. The current study examined CD4 nadir in relation to domain-specific NC decline. 132 HIV + adults from the Temple/Drexel Comprehensive NeuroHIV Center, Clinical and Translational Research Support Core Cohort were administered comprehensive NC assessments longitudinally, with last visit occurring an average of 12years after CD4 nadir. Linear mixed models were used to examine CD4 nadir in relation to longitudinal NC trajectories in three empirically identified NC domains: speed/executive function (S/EF), visuospatial memory (VM), and verbal fluency (VF). CD4 nadir was associated with change in VF (p = 0.020), but not with S/EF or VM. Specifically, those with CD4 nadir < 200 demonstrated increasing VF over time (p = .002), whereas those with CD4 nadir > 200 demonstrated stable VF (p = .568), though these differing trajectories may partly reflect regression to the mean or differential practice effect. CD4 dynamics over time were analyzed as potential mechanisms for the identified associations, with mixed findings. While low CD4 nadir has been associated with weaker neurocognition among people living with HIV, the results of this study suggest that low CD4 nadir is not associated with ongoing decline a decade later. Nadir-related deficits in VF may be stable or even improve over time, possibly reflecting the beneficial cognitive effects of long-term treatment and immune reconstitution.

Capturing longer term surgical outcome measures as part of routine care of breast cancer patients

IntroductionThe transition away from routine clinical follow up after breast cancer towards imaging surveillance and patient-initiated contact limits opportunities for patients and doctors to communicate about the long-term effects of treatment. The ABS oncoplastic guidelines (2021) recommend that post-operative 2D images and patient-reported outcomes (PROMs) are routinely collected but give no guidance as to how best to implement this. MethodsFrom December 2019 until March 2024, women due for their year 3 or 5 surveillance mammogram at The Royal Marsden Sutton site were invited to complete a BREAST-Q questionnaire and attend medical photography. Panel assessment of photographs was undertaken. Results were presented to the oncoplastic MDT, including summary PROMs and illustrative case presentations. Free-text comments were shared with the relevant teams. Associations between demographic or clinic-pathological factors and uptake were investigated. ResultsOf the 1211 women invited, 246 patients (20.3 %) completed BREAST-Q questionnaires, 182 (15.0 %) attended for medical photography and 114 (9.4 %) completed both. Uptake was not associated with age, ethnicity or surgical factors but patients with higher BMI were less likely to respond to the questionnaire. Patients who had undergone complex oncoplastic procedures were more likely to respond than those who had simple procedures. Patient-reported outcome results were in line with the published literature. ConclusionReviewing images with their paired PROMs and discussing free-text feedback was instructive for the team. Work is needed to identify barriers to patient participation and improve uptake to be representative of the overall patient population. Quantifying appearance in photographs would help summarise aesthetic outcome data.

Field evaluation of hydrogen peroxide bath technique for controlling sea lice (Lepeoptheirus spinifer) infestation in snubnose pompano (Trachinotus blochii)

Sea lice infestations can pose significant challenges in the aquaculture sector, affecting fish health and overall production. In the search for effective and eco-friendly solutions, hydrogen peroxide bath treatment has been considered as one of the promising methods. This is the first study to evaluate the field efficacy of hydrogen peroxide bath technique against sea lice infestation on cage-cultured snubnose pompano (Trachinotus blochii). Sea lice was identified as Lepeophtheirus spinifer using morphological description. Naturally-infested snubnose pompano stocked in 2 ×3×2 m3 net cages at 15 fish/cage at the Igang Marine Station of SEAFDEC/AQD, in Guimaras, Philippines were treated in triplicates with two hydrogen peroxide concentrations (1500 and 2000 ppm) in comparison to a control (seawater only) for 20 minutes at 32.8 ± 0.7 ppt and 28.9 ± 0.3 °C and were monitored at 3rd and 7th day post-treatment. The total mean intensity of sea lice, mean intensity per life stages (copepodid, chalimus I, chalimus II, pre-adult I, pre-adult II, adult male and adult female), and the 12-h viability of scraped male and adult female L. spinifer from the treatment groups were evaluated. The total mean intensity of sea lice in the treated groups at 3 day post-treatment was significantly lower than the control group (p<0.001). A possible re-infection of sea lice was observed 7 days post-treatment as explained by the slight increase in the mean intensity in the treated groups. However, no mortalities of pompano were recorded throughout the experiment. In addition, adult female lice were absent in the treated group while adult male lice were only detected in the 1500 ppm treatment group at a very low mean intensity. The viability test also showed that all sea lice were not able to recover after 12 h whereas a 100 % recovery rate was noted in the control group. Results suggest that the 1500 and 2000 ppm hydrogen peroxide concentrations are effective in reducing sea lice infestation on cage-cultured snubnose pompano. However, a long-term effect of hydrogen peroxide treatment on sea lice needs further investigation.

Relapse during and after regular single-dose rituximab treatment in adult patients with steroid-dependent nephrotic syndrome.

Rituximab is widely used in patients with steroid-dependent nephrotic syndrome. However, information on the effect of long-term rituximab treatment is limited. This study examined the efficacy of rituximab during and after treatment in adult patients with steroid-dependent nephrotic syndrome. This retrospective cohort study included 30 patients with steroid-dependent nephrotic syndrome. Patients received regular single-dose rituximab (500mg) intravenously every 6months. Discontinuation of rituximab was considered after four to six doses if there was no recurrence of nephrotic syndrome. Glucocorticoid discontinuation with remission, first relapse after rituximab initiation, and relapse after regular rituximab treatment discontinuation were evaluated. The median age was 38 (range 18-67) years. Of 30 patients, 13 and 17 were men and women, respectively. Prior to rituximab treatment, the median number of nephrotic syndrome relapses in the patients was 5 (range 2- > 20). The 1year discontinuation rate of glucocorticoids with remission was 83%. All patients discontinued glucocorticoid treatment at least once until 3years and 7months. The 1 and 2year relapse rates after initiation of rituximab treatment were 0% and 3%, respectively. 25 patients discontinued regular rituximab treatment after a median number of six (4-12) doses. Six patients relapsed after discontinuing rituximab, and the 1 and 2year relapse rates after the last regular rituximab treatment were 9% and 25%, respectively. All patients with steroid-dependent nephrotic syndrome who received rituximab could discontinue glucocorticoid treatment with remission, and three-fourths of the patients remained in remission for > 2years after discontinuing rituximab treatment.

Improving Diagnosis and Care for Patients With Sarcoma: Do Real-World General Practitioners Data and Prospective Data Collections Have a Place Next to Clinical Trials?

There has been growing interest in the use of real-world data (RWD) to address clinically and policy-relevant (research) questions that cannot be answered with data from randomized controlled trials (RCTs) alone. This is, for example, the case in rare malignancies such as sarcomas as limited patient numbers pose challenges in conducting RCTs within feasible timeliness, a manageable number of collaborators, and statistical power. This narrative review explores the potential of RWD to generate real-world evidence (RWE) in sarcoma research, elucidating its application across different phases of the patient journey, from prediagnosis to the follow-up/survivorship phase. For instance, examining electronic health records (EHRs) from general practitioners (GPs) enables the exploration of consultation frequency and presenting symptoms in primary care before a sarcoma diagnosis. In addition, alternative study designs that integrate RWD with well-designed observational RCTs may offer relevant information on the effectiveness of clinical treatments. As, especially in cases of ultrarare sarcomas, it can be an extreme challenge to perform well-powered randomized prospective studies. Therefore, it is crucial to support the adaptation of novel study designs. Regarding the follow-up/survivorship phase, examining EHR from primary and secondary care can provide valuable insights into identifying the short- and long-term effects of treatment over an extended follow-up period. The utilization of RWD also comes with several challenges, including issues related to data quality and privacy, as described in this study. Notwithstanding these challenges, this study underscores the potential of RWD to bridge, at least partially, gaps between evidence and practice and holds promise in contributing to the improvement of sarcoma care.

Efficacy of physiotherapy treatment in medium and long term in adults with fibromyalgia: an umbrella of systematic reviews.

To summarise the available evidence and assess the effectiveness of medium and long-term physiotherapy treatment in adults with fibromyalgia (FM). This systematic review was registered in PROSPERO: CRD42023388356. The databases searched were MEDLINE, PEDro, Scopus, Cinhal, LatinIndex, and Cochrane, using the following keywords: "fibromyalgia", "physiotherapy", "treatment", "therapeutic exercise", "TENS", "laser therapy" and "manual therapy." The included articles analysed treatments with active or passive physiotherapy approaches in patients with FM. The variables included structural characteristics, such as: author, publication year, research question, and main outcome variables. The data on the findings of the articles comprised the following aspects: number of participants, intervention, follow-up, results, and principal conclusions. Thirty-three articles were analysed, with an overall PRISMA score of 18.63±3.36. The active treatment methods analysed were: movement and body awareness therapies (stretching, tai chi, yoga and Pilates); hydrotherapy; physical or aerobic exercise; and multidisciplinary therapy. The passive therapies analysed were: manual therapy; repetitive transcranial magnetic stimulation (rTMS); and other therapies (hyperbaric oxygen therapy, vibration therapy, virtual reality, transcutaneous electric nervous stimulation (TENS), pain neuroscience education, and acupuncture). Evidence was found on the positive effect of physiotherapy treatment on the signs and symptoms of fibromyalgia, such as pain, impairment of physical capacity and worse quality of life. The effectiveness of the active and passive therapies analysed in the management of the symptoms and signs of the disease was positive in most of the studies. However, more specific descriptions of the treatment protocol, frequency, intensity and treatment dose are required to reach a consensus, as well as primary studies for a more extended follow-up period to better evaluate long-term effects.

Impact of aromatase inhibitors on mortality and hospitalization costs in patients with breast cancer: A National Inpatient Sample analysis 2020.

e13160 Background: Breast cancer is a significant public health concern globally, affecting millions of individuals each year. Aromatase inhibitors are a class of medications commonly used in the treatment of hormone receptor-positive breast cancer. The significance of the study lies in the impact of aromatase inhibitors on mortality and also healthcare-related costs for the treatment of breast cancer. Methods: The National Inpatient Sample database (2020) was used to identify adult patients with breast cancer using ICD-10 codes. Demographics (age, race, sex, region, and hospital size), co-morbidities, and hospitalization costs were compared between the two groups of patients: those who are on aromatase inhibitors and those who are not. The odds of mortality were analyzed. A p&lt;0.05 was considered statistically significant. Results: Out of 166870 patients who had breast cancer, 12975(7.7%) were on aromatase inhibitors. The aromatase inhibitors group was relatively older (median age, 69.4 years vs 64 years) and predominantly white (71.50% vs 66%) compared to the non-aromatase inhibitors group. The prevalence of heart failure and osteoporosis was greater in the aromatase inhibitors group than in the non-aromatase inhibitors group. The adjusted odds ratio of mortality in the aromatase inhibitors group was 0.45, 95% CI (0.39-0.50, p&lt;0.0001). Furthermore, the average total cost of hospitalization in the aromatase inhibitor group was $6426 less than the non-aromatase inhibitor group. Conclusions: Our study findings indicate that breast cancer patients treated with aromatase inhibitors experienced lower odds of mortality and lesser costs of hospitalization. However, the aromatase inhibitor group was found to have a higher prevalence of heart failure and osteoporosis. Hence, further research needs to be done on potential adverse effects and long-term effects of the aromatase inhibitors treatment.

Evaluation of the neuroprotective effect of antipsychotics by serum quantification of protein S100B

ObjectiveThis research delves into the intricate interplay between antipsychotic medications and neuroprotection focusing on the S100B protein—a central player in the regulation of neuroapoptotic activity. MethodBlood samples were collected to assess serum S100B protein levels using an immunoassay of immunoelectrochemiluminescence. The first two samples were collected with a 3-month interval between each, and the third sample was obtained 6 months after the previous one. Changes in S100B protein levels throughout the study were assessed using Friedman's ANOVA test. This was followed by the Wilcoxon signed-rank test with Bonferroni correction to account for multiple comparisons. ResultsThis study involved 40 patients diagnosed with severe mental disorders (34 schizophrenia, 4 schizoaffective disorder, 1 bipolar disorder, and 1 borderline personality disorder). These patients had been receiving antipsychotic treatment for an average duration of 17 years. The results revealed that the S100B protein remained within physiological levels (median values 39.0 ng/L for the first sample, median values 41.0 ng/L for the second sample, and median values 40.5 ng/L for the third sample) with no significant changes (p = 0.287), with all anti-psychotic medicaments values consistently below 50 ng/L, a lower value compared to maximum range of 105 ng/L. Importantly, there were no significant differences in S100B protein levels between patients on monotherapy and those on combination antipsychotic therapy (p = 0.873), suggesting that combination therapy did not increase neuroapoptotic activity. ConclusionsThese findings provide compelling evidence for the potential neuroprotective effects of long-term antipsychotic treatment in individuals with severe mental disorders. By maintaining physiological levels of the S100B protein, antipsychotic medications may help protect against neuronal damage and dysfunction. This research contributes valuable insights into the neuroprotective mechanisms of antipsychotic drugs, enhancing our understanding of their potential benefits in the treatment of severe mental disorders.

Understanding the dynamics of TKI-induced changes in the tumor immune microenvironment for improved therapeutic effect

BackgroundThe dynamic interplay between tyrosine kinase inhibitors (TKIs) and the tumor immune microenvironment (TME) plays a crucial role in the therapeutic trajectory of non-small cell lung cancer (NSCLC). Understanding the...

The chained difference-in-differences

This paper studies the identification, estimation, and inference of long-term (binary) treatment effect parameters when balanced panel data is not available, or consists of only a subset of the available data. We develop a new estimator: the chained difference-in-differences, which leverages the overlapping structure of many unbalanced panel data sets. This approach consists in aggregating a collection of short-term treatment effects estimated on multiple incomplete panels. Our estimator accommodates (1) multiple time periods, (2) variation in treatment timing, (3) treatment effect heterogeneity, (4) general missing data patterns, and (5) sample selection on observables. We establish the asymptotic properties of the proposed estimator and discuss identification and efficiency gains in comparison to existing methods. Finally, we illustrate its relevance through (i) numerical simulations, and (ii) an application about the effects of an innovation policy in France.

Omeprazole taken once every other day can effectively prevent aspirin-induced gastrointestinal mucosal damage in rats

BackgroundProton-pump inhibitors (PPIs) prevent aspirin-associated gastric and duodenal mucosal damage. However, long-term use of PPIs can lead to various adverse reactions, such as gastric polyps and enterochromaffin-like cell hyperplasia. Current research indicates that the abovementioned adverse reactions are mainly related to hypergastrinemia. We investigated whether low-frequency administration of omeprazole could effectively repair aspirin-induced mucosal damage and reduce the increase in gastrin levels associated with long-term use of PPIs.MethodsSprague‒Dawley rats were divided into four treatment groups: daily aspirin, daily aspirin and omeprazole once every day (qd), daily aspirin and omeprazole once every other day (qod), and daily aspirin and omeprazole once every three days (1/d3). After 15 days of feeding, blood samples were collected, and the stomachs of sacrificed rats were subjected to macroscopic, histological, and immunohistochemical studies. Moreover, in clinical practice, patients with peptic ulcers caused by aspirin took a standard dose of omeprazole (20 mg) every other day. Two months later, gastroscopy was performed to examine the healing of the ulcers.ResultsBoth the omeprazole qd and omeprazole qod administrations effectively prevented aspirin-induced gastric peptic ulcers, with no significant difference between the two groups in the inhibition of parietal cell secretion of gastric acid and cell apoptosis. However, omeprazole 1/d3 failed to completely prevent aspirin-induced gastric mucosal injury. Notably, the gastrin levels, cell proliferation ability and cholecystokinin B receptor expression of the omeprazole qd group were significantly higher than those of the omeprazole qod group. In clinical work, patients with peptic ulcers caused by aspirin were given a standard dose of omeprazole every other day, and their ulcers healed after 2 months, as observed by gastroscopy.ConclusionsOmeprazole administration once every other day can effectively prevent aspirin-induced peptic ulcers and reduce hypergastrinemia, which may reduce the long-term adverse effects of PPI treatment.

The effect of long-term magnesium treatment on changes in hepatic autophagic and apoptotic ability of type 2 diabetic female rats and their offspring

AimWe investigated the role of magnesium sulfate (MgSO4) and insulin administration on improved autophagy and apoptosis to prevent diabetes in high-fat diet (HFD)-diabetic parents and their offspring. MethodsA HFD and a low dose of streptozotocin (STZ) were used to induce diabetes. Animals were assigned to four groups: non-diabetic control (NDC), diabetic control (DC), the diabetic group received insulin (INS), and the diabetic group received magnesium (MG). The duration of the research was 6 months, and offspring were fed a normal diet for 4 months. Blood glucose was determined weekly in rats (parents and offspring). The gene expression of adenosine monophosphate-activated protein kinase (AMPKα1), Bcl-2-interacting myosin-like coiled-coil protein (Becline-1), P62, Microtubule-associated protein 1 light chain 3 (LC3-II), and caspase-9 of liver tissues were assessed using Real-time PCR. ResultThe analysis of maternal gene expression data showed that treatment with MG and INS considerably augmented the AMPKα1 and LC3-II genes expression and diminished P62 and caspase-9 expression. Also, a significant decrease in the expression of AMPKα1, LC3-II, P62, and Becline-1 was observed in the female offspring in the MG and INS groups. Significant alterations in levels of AMPKα1, Beclin-1, P62, and caspase-9 mRNA were not observed between groups in male offspring, but the expression of LC3-II considerably diminished in the groups compared with the DC group. DiscussionOur data demonstrated that MG supplementation strengthened the mother's autophagy and reduced the transmission of damage to the female offspring. In the male offspring, the transmission of damage was generally less, and MG improved the autophagy condition in the male offspring. Our findings support the presence of a link between autophagy induction and MG-modified biomaterials and determine a potential mechanism of MG-mediated diabetes and autophagy.
