Review
BACKGROUND
Jaffe-Campanacci syndrome is a rare syndrome, characterized by multiple non-ossifying fibromas (NOF) and cafe-au-lait patches. The name was coined in 1982 by Mirra after Jaffe who first described the case in 1958. Although it's suggested there is a relation with Neurofibromatosis type 1, there is still no consensus on whether Jaffe-Campanacci syndrome is a subtype or variant of neurofibromatosis-1(NF-1).
CASE PRESENTATION
In this article, we present a case series of 2 patients. The first case is a 13-year-old male with Jaffe-Campanacci syndrome who presented with a distal femur fracture. His father had positive features of both Jaffe-Campanacci syndrome and NF-1, while his sister only had features of NF-1, so we presented both.
CONCLUSION
Jaffe-Campanacci has a clear relationship with type 1 neurofibromatosis, which still has to be genetically established. Due to the presence of several large non-ossifying fibromas of the long bones, it is linked to a significant risk of pathological fractures. We concur with previous authors, that an osseous screening program should be performed for all patients with newly diagnosed type 1 neurofibromatosis, to identify non-ossifying fibromas and assess the potential for pathological fracture. Moreover, siblings of patients with NF-1 should be screened for multiple NOFs that may carry a high risk of pathological fractures.

Randomized Controlled Trial
Process evaluation protocol plan for a home-based physical activity intervention versus educational intervention for persistent taxane-induced peripheral neuropathy (B-HAPI study): a randomized controlled trial.
BACKGROUND
Evaluation publications typically summarize the results of studies to demonstrate the effectiveness of an intervention, but little is shared concerning any changes implemented during the study. We present a process evaluation protocol of a home-based gait, balance, and resistance exercise intervention to ameliorate persistent taxane-induced neuropathy study according to 7 key elements of process evaluation.
METHODS
The process evaluation is conducted parallel to the longitudinal, randomized control clinical trial examining the effects of the home-based gait, balance, and resistance exercise program for women with persistent peripheral neuropathy following treatment with taxanes for breast cancer (IRB approval: Pro00040035). The flowcharts clarify how the intervention should be implemented in comparable settings, fidelity procedures help to ensure the participants are comfortable and identify their individual needs, and the process evaluation allows for the individual attention tailoring and focus of the research to avoid protocol deviation.
CONCLUSIONS
The publication of the evaluation protocol plan adds transparency to the findings of clinical trials and favors process replication in future studies. The process evaluation enables the team to systematically register information and procedures applied during recruitment and factors that impact the implementation of the intervention, thereby allowing proactive approaches to prevent deviations from the protocol. When tracking an intervention continuously, positive or negative intervention effects are revealed early on in the study, giving valuable insight into inconsistent results. Furthermore, a process evaluation adds a participant-centered element to the research protocols, which allows a patient-centered approach to be applied to data collection.

OBJECTIVES
Approximately 60% of cancer survivors receiving neurotoxic chemotherapy experience chemotherapy-induced peripheral neuropathy (CIPN) (eg, hand and foot numbness, tingling, or pain). There is only one recommended pharmacological treatment (duloxetine) and one modestly beneficial nonpharmacological treatment (exercise) for CIPN. However, data suggest national guideline recommendations are not routinely practiced. Further, less is known about nurses' CIPN management practices. The purpose of this convergent mixed methods study was to explore oncology clinicians' self-reported practices and perceptions regarding CIPN prevention and management.
METHODS
Oncology clinicians at three cancer centers completed a survey about their recommendations for CIPN prevention and management in practice. A subset of clinicians also participated in a semi-structured interview to explore their perspectives of and motivations for implementing CIPN assessment, prevention, and management in practice. Quantitative data were described (eg, frequency or median) and qualitative data were analyzed using inductive content analysis.
RESULTS
This study (N = 44 survey responses; n = 9 interviews) resulted in four themes: (1) clinicians primarily recommend gabapentin for CIPN management and often observe cryotherapy used for CIPN prevention, but these interventions are complicated by discomfort, intolerable side effects, and efficacy concerns; (2) clinicians perceive CIPN as troublesome and desire additional information and resources regarding CIPN prevention and management; (3) CIPN-related education provided by clinicians may be limited by patient retention of the amount of education received about cancer treatment and other factors; (4) clinicians use subjective CIPN assessment to screen at each visit for common CIPN symptoms (eg, numbness or tingling) and the impact of symptoms on day-to-day activities.
CONCLUSIONS
Discrepancies persist between evidence-based guidelines on CIPN management and current oncology clinician practices.
IMPLICATIONS FOR NURSING PRACTICE
Clinician involvement is needed when developing education and resources to help oncology clinicians provide the most evidence-based care to potentially prevent and manage their patients' CIPN.

Chronic administration of cannabinoid agonists ACEA (CB1), AM1241 (CB2), and CP55,940 (mixed CB1/CB2) induce sex-specific differences in tolerance and sex hormone changes in a chemotherapy-induced peripheral neuropathy.
Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of chemotherapy treatment, routinely manifesting as increased pain sensitivity (allodynia) in distal extremities. Despite its prevalence, effective treatment options are limited. Cannabinoids are increasingly being evaluated for their ability to treat chronic pain conditions, including CIPN. While previous studies have revealed sex differences in cannabinoid-mediated antinociception in acute and chronic pain models, there is a paucity of studies addressing potential sex differences in the response of CIPN to cannabinoid treatment. Therefore, we evaluated the long-term anti-allodynic efficacy of CB-selective (ACEA), CB-selective (AM1241), and CB/CB mixed (CP55,940) agonists in the cisplatin CIPN model, using both male and female mice. CB selective agonism was observed to have sex differences in the development of tolerance to anti-allodynic effects, with females developing tolerance more rapidly than males, while the anti-allodynic effects of selective CB agonism lacked tolerance development. Compound-specific changes to the female estrous cycle and female plasma estradiol levels were noted, with CB selective agonism decreasing plasma estradiol while CB selective agonism increased plasma estradiol. Chronic administration of a mixed CB/CB agonist resulted in increased mRNA expression of proinflammatory cytokines and endocannabinoid regulatory enzymes in female spinal cord tissue. Ovarian tissue was noted to have proinflammatory cytokine mRNA expression following administration of a CB acting compound while selective CB agonism resulted in decreased proinflammatory cytokines and endocannabinoid regulatory enzymes in testes. These results support the need for further investigation into the role of sex and sex hormones signaling in pain and cannabinoid-mediated antinociceptive effects. CIPN is a common side effect of chemotherapy. We have found that both CB1 and CB2 receptor agonism produce antinociceptive effects in a cisplatin CIPN model. We observed that tolerance to CB1-mediated antinociception developed faster in females and did not develop for CB¬2-mediated antinociception. Additionally, we found contrasting roles for CB1/CB¬2 receptors in the regulation of plasma estradiol in females, with CB1 agonism attenuating estradiol and CB¬2 agonism enhancing estradiol. These findings support the exploration of cannabinoid agonists for CIPN.

INTRODUCTION
Chemotherapy-induced peripheral neuropathy (CIPN) affects patients' quality of life and treatment effectiveness. Gabapentinoids, like gabapentin and pregabalin, are often used for CIPN treatment, but their efficacy and safety remain uncertain. This study reviews and analyses randomised controlled trial data on this topic.
MATERIALS/METHODS
We searched PubMed, Embase and Cochrane CENTRAL until 29 August 2022 for studies on gabapentinoid use in CIPN. Meta-analysis was performed using RevMan V.5.4 and the Metafor package in R. Outcomes included pain scores, quality of life and adverse drug events.
RESULTS
For the prevention setting, our meta-analysis shows that pregabalin did not significantly improve average pain (standardised mean difference (SMD) -0.14, 95% CI -0.51 to 0.23; I=26% (95% CI 0% to >98%)) or quality of life (mean difference (MD) 2.5, 95% CI -4.67 to 9.67; p=0.49) in preventing CIPN compared with placebo. However, it showed a potential trend towards reducing the worst pain (SMD -0.28, 95% CI -0.57 to 0.01; I=0% (95% CI 0% to 98%; p=0.06)). For the treatment setting, some studies have shown a potential therapeutic effect of gabapentinoids. However, the results are not consistent between studies. Given the studies' heterogeneity, a meta-analysis in treatment setting was not performed.
CONCLUSION
There is limited evidence to support the use of gabapentinoids in CIPN. In prevention setting, gabapentinoids do not significantly prevent CIPN. In treatment setting, studies have been inconsistent in their conclusions, lacking definitive benefits over placebo. More comprehensive and higher quality research is needed in the future.

Randomized Controlled Trial
OBJECTIVE
To determine the prevalence of insomnia and the effectiveness of its treatment in patients with a painful form of diabetic polyneuropathy (DPN).
MATERIAL AND METHODS
Fifty patients with the painful form of DPN were randomly divided into 2 groups: the standard therapy group (ST) and the extended therapy group (ET). In the ST group, a single lesson on sleep hygiene was conducted, in the ET group there were 3-4 face-to-face individual sessions for the treatment of insomnia for two weeks. Both groups were interviewed at the time of hospitalization, after 3 and 6 months. The severity of polyneuropathy and the nature of neuropathic pain were assessed using the Neuropathic Neuropathy Impairment Score in the Lower Limbs (NIS-LL) and the Neuropathy Total Symptom Score - 9 (NTSS-9); the intensity of pain was assessed using a Visual Analog Scale (VAS). Sleep disorders were analyzed using the Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI).
RESULTS
Sleep disorders of varying severity were observed in 82% of patients in the initial survey. In both groups, improvement in sleep quality was noted during treatment, but significantly better results were in the ET group, the ISI score after 6 months was 7.15±2.08 for the ST group and 3.07±2.49 for the ET group (<0.0001). In the ST group, there was no significant decrease in the intensity of pain and the severity of polyneuropathy in dynamics. In the ET group, a significant decrease in NTSS-9 and VAS scores was found during the initial survey and after 6 months (<0.0001). The intensity of pain also significantly decreased in the ET group compared with the ST group (<0.0001) at the end of follow-up, which indicates the importance of sleep normalization in the treatment of neuropathic pain.
CONCLUSION
Most patients with the painful form of DPN have insomnia. Treatment of insomnia has shown its effectiveness as part of a multimodal approach to the managing of neuropathic pain in DPN and improving the quality of life of patients.

Chitosan alleviates symptoms of Parkinson's disease by reducing acetate levels, which decreases inflammation and promotes repair of the intestinal barrier and blood-brain barrier.
Studies have shown that chitosan protects against neurodegenerative diseases. However, the precise mechanism remains poorly understood. In this study, we administered chitosan intragastrically to an MPTP-induced mouse model of Parkinson's disease and found that it effectively reduced dopamine neuron injury, neurotransmitter dopamine release, and motor symptoms. These neuroprotective effects of chitosan were related to bacterial metabolites, specifically short-chain fatty acids, and chitosan administration altered intestinal microbial diversity and decreased short-chain fatty acid production in the gut. Furthermore, chitosan effectively reduced damage to the intestinal barrier and the blood-brain barrier. Finally, we demonstrated that chitosan improved intestinal barrier function and alleviated inflammation in both the peripheral nervous system and the central nervous system by reducing acetate levels. Based on these findings, we suggest a molecular mechanism by which chitosan decreases inflammation through reducing acetate levels and repairing the intestinal and blood-brain barriers, thereby alleviating symptoms of Parkinson's disease.

Clinical outcomes of catheter ablation for atrial fibrillation, atrial flutter, and atrial tachycardia in wild-type transthyretin amyloid cardiomyopathy: a proposed treatment strategy for catheter ablation in each arrhythmia.
AIMS
Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF). This study aimed to investigate the outcomes of catheter ablation (CA) for AF/AFL/AT in patients with ATTRwt-CM and propose a treatment strategy for CA.
METHODS AND RESULTS
A cohort study was conducted on 233 patients diagnosed with ATTRwt-CM, including 54 who underwent CA for AF/AFL/AT. The background of each arrhythmia and the details of the CA and its outcomes were investigated. The recurrence-free rate of AF/AFL/AT overall in ATTRwt-CM patients with multiple CA was 70.1% at 1-year, 57.6% at 2-year, and 44.0% at 5-year follow-up, but CA significantly reduced all-cause mortality [hazard ratio (HR): 0.342, 95% confidence interval (CI): 0.133-0.876, P = 0.025], cardiovascular mortality (HR: 0.378, 95% CI: 0.146-0.981, P = 0.045), and HF hospitalization (HR: 0.488, 95% CI: 0.269-0.889, P = 0.019) compared with those without CA. There was no recurrence of the cavotricuspid isthmus (CTI)-dependent AFL, non-CTI-dependent simple AFL terminated by one linear ablation, and focal AT originating from the atrioventricular (AV) annulus or crista terminalis eventually. Twelve of 13 patients with paroxysmal AF and 27 of 29 patients with persistent AF did not have recurrence as AF. However, all three patients with non-CTI-dependent complex AFL not terminated by a single linear ablation and 10 of 13 cases with focal AT or multiple focal ATs originating beyond the AV annulus or crista terminalis recurred even after multiple CA.
CONCLUSION
The outcomes of CA for ATTRwt-CM were acceptable, except for multiple focal AT and complex AFL. Catheter ablation may be aggressively considered as a treatment strategy with the expectation of improving mortality and hospitalization for HF.

Urothelial carcinoma (UC) is a refractory disease for which achieving satisfactory outcomes remains challenging with current surgical interventions. Antibody-drug conjugates (ADCs) are a novel class of targeted therapeutics that have demonstrated encouraging results for UC. Although there is a limited number of high-quality randomized control trials (RCTs) examining the use of ADCs in patients with UC, some prospective non-randomized studies of interventions (NRSIs) provide valuable insights and pertinent information. We aim to assess the efficacy and safety of ADCs in patients with UC, particularly those with locally advanced and metastatic diseases. A systematic search was conducted across PubMed, Embase, the Cochrane Library, and Web of Science databases to identify pertinent studies. Outcomes, such as the overall response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), adverse events (AEs), and treatment-related adverse events (TRAEs), were extracted for further analyses. Twelve studies involving 1,311 patients were included in this meta-analysis. In terms of tumor responses, the pooled ORR and DCR were 40% and 74%, respectively. Regarding survival analysis, the pooled median PFS and OS were 5.66 months and 12.63 months, respectively. The pooled 6-month PFS and OS were 47% and 80%, while the pooled 1-year PFS and OS were 22% and 55%, respectively. The most common TRAEs of the ADCs were alopecia (all grades: 45%, grades ≥ III: 0%), decreased appetite (all grades: 34%, grades ≥ III: 3%), dysgeusia (all grades: 40%, grades ≥ III: 0%), fatigue (all grades: 39%, grades ≥ III: 5%), nausea (all grades: 45%, grades ≥ III: 2%), peripheral sensory neuropathy (all grades: 37%, grades ≥ III: 2%), and pruritus (all grades: 32%, grades ≥ III: 1%). The meta-analysis in this study demonstrates that ADCs have promising efficacies and safety for patients with advanced or metastatic UC. https://www.crd.york.ac.uk/prospero/, identifier: CRD42023460232.
