A pilot study of tofacitinib citrate with 308-nm excimer laser for the treatment of vitiligo.

Vitiligo is a clinically prevalent acquired skin disorder characterized by depigmentation. Currently, the therapeutic options for vitiligo are restricted, and numerous issues exist, such as a prolonged treatment course, unsatisfactory therapeutic efficacy, adverse reactions, and a high propensity for recurrence after treatment cessation. To assess the safety and efficacy of combined treatment involving oral tofacitinib citrate (TC) and a 308-nm excimer laser (EL), with the aim of discovering a rapid and effective treatment approach to minimize the side effects of various drugs. A total of 63 patients with progressive vitiligo and a Vitiligo Disease Activity Score (VIDA) score of four from January 2022 to January 2024 were enrolled and divided into three groups. The three groups were the TC combined with 308-nm EL and methylprednisolone treatment group, the TC and 308-nm EL treatment group, and the methylprednisolone treatment alone group. The treatment was continued for 24 weeks. Finally, assessment of therapy outcomes was performed. When TC was combined with 308-nm EL and methylprednisolone treatment, the effect was more rapid. When TC was combined with 308-nm EL, it had a more favorable treatment effect than that of methylprednisolone alone, despite having a slower effect onset. After 24 weeks of treatment, there was no significant difference between the two groups in terms of the total response rate or significant efficiency. However, when only methylprednisolone treatment was applied, the effect is relatively slow and inefficient. This study confirmed the rapid and efficient treatment of vitiligo through the combination of TC and 308-nm EL, and no serious adverse reactions were reported, which could offer an optimal treatment plan for patients with vitiligo.

CCR8/CCL1 and CXCR3/CXCL10 axis mediated memory T cell activations in recalcitrant drug-induced hypersensitivity patients.

As a drug-induced hypersensitivity syndrome, drug reaction with eosinophilia and systemic symptoms (DRESS) is potentially fatal. Most patients with DRESS recover within a few weeks; however, some patients may suffer from a prolonged disease course and develop autoimmune sequelae. We investigated the immune mechanism and therapeutic targets of patients with recalcitrant DRESS with a prolonged disease course. A total of 32 patients with recalcitrant DRESS with a prolonged treatment course ≥8 weeks, 28 patients with short-duration DRESS with a treatment course <2 weeks, and 26 healthy individuals were enrolled in the study for analysis. Bulk transcriptome results demonstrated that mRNA expression levels of CCR8 and CXCR3 were significantly increased in the blood samples from patients in the acute stage of prolonged DRESS (adjusted p-values: CCR8=1.50×10-9 and CXCR3=2.60×10-4, respectively, for comparison of patients with prolonged DRESS to the healthy donor group). Serum and skin lesional concentrations of CCL1 and CXCL10, as the ligands of CCR8 and CXCR3, respectively, were significantly elevated in patients with prolonged DRESS as compared to those patients with short-duration DRESS. The results from high-parameter flow cytometry and autoantibody screening also identified significant escalations of CD8+ GNLY+CXCR3+effector memory T cells, CD8+central memory T cells, CD4+CCR8+Th2 cells, and IgG-anti-HES6 autoantibodies in patients with prolonged DRESS. Furthermore, in vitro blocking assays revealed that JAK inhibitors (mainly tofacitinib and upadacitinib) significantly decreased the release of CCL1 and CXCL10, and some patients with prolonged DRESS were successfully treated with JAK inhibitors. JAK inhibitors (tofacitinib and upadacitinib) were associated with decreased concentrations of CCL1 and CXCL10, suggesting that they may attenuate CCR8/CCL1- and CXCR3/CXCL10-axis-mediated memory T cell activation, which contribute to disease pathogenesis for patients with recalcitrant DRESS and a long-term treatment course.

Erysipelothrix rhusiopathiae-associated bloodstream infection in a patient with systemic lupus erythematosus: a case report and literature review

Introduction. Systemic human infections caused by Erysipelothrix rhusiopathiae have been increasingly reported especially within immunocompromised hosts and those with significant occupational exposure to livestock and aquatic animals. We report a case of E. rhusiopathiae bacteraemia in a patient with systemic lupus erythematosus (SLE) and present a literature review on clinical outcomes and microbiologic diagnosis for this organism. Case presentation. A 43-year-old female patient was reporting a 1-month history of intermittent fevers. She recently increased her immunosuppression medication for her underlying SLE on the advice of her rheumatologist. The patient sustained a finger laceration from butchering cattle meat 2 weeks after the onset of her initial symptoms, with worsening index finger swelling and increased febrile episodes. Two weeks post-injury, multiple blood cultures were drawn, and each isolated Gram-positive bacilli. Given her recurrent intermittent fevers, there was a concern for ongoing infection, and therefore, intravenous vancomycin was started with prompt referral to an outpatient parenteral antibiotic therapy clinic. The Gram-positive bacillus was confirmed as E. rhusiopathiae via matrix-assisted laser desorption/ionization-time of flight analysis. Given intrinsic resistance to vancomycin, vancomycin was switched to intravenous ceftriaxone as targeted antimicrobial therapy for 2 weeks. Reassuringly, there was no echocardiographic evidence of infective endocarditis, warranting the prolonged treatment course. Post-treatment, she remained symptom-free with the resolution of joint symptoms and fevers. Conclusion. Our report illustrates a case of E. rhusiopathiae bacteraemia from an immunodeficient host, with prompt microbiologic diagnosis and intervention with appropriate antimicrobial coverage. Literature reflects the rarity of this infection, predilections to specific susceptible hosts and the importance of raising awareness of zoonotic infections.

Antibiotic Appropriateness for Urinary Tract Infections in Children.

We examined local prescribing patterns across the entire treatment course for children treated for uncomplicated urinary tract infection (UTI) to determine opportunities for antibiotic stewardship initiatives. We conducted a retrospective review of emergency department and inpatient encounters for febrile and afebrile UTI in a children's hospital from 2021 to 2022. An antibiotic spectrum ranking was established, and providers' choices were assessed for appropriateness on the basis of the individuals' urine culture (UCx). Groups were stratified by fever presence and compared using χ2, Fisher's exact, and Mann-Whitney U tests. Of 172 encounters (83% emergency department), 99 (58%) had a positive UCx. Eighty (80%) grew Escherichia coli, with 67 (84%) being susceptible to cefazolin (minimum inhibitory concentration ≤16 mg/L). There were 229 antibiotic regimens and 39 (17%) were appropriate. Inappropriate antibiotic choices included unnecessary use of broad-spectrum antibiotics and misdiagnosed UTI. Grouping by encounter, at least 1 dose of a third cephalosporin was given in 51% of encounters, and 80% of these received it unnecessarily because of UTI misdiagnosis or suitability of a narrower-spectrum antibiotic. The median prescribed antibiotic duration was 7 days (interquartile range 7-10). Of 73 encounters with UCx growing mixed flora or a nonuropathogen, only 29 (40%) had antibiotics discontinued. Confirmed UTI was associated with fever and nitrite positivity. Our study revealed high prevalence of inappropriate antibiotics, particularly unnecessary prescribing of third cephalosporin, prescriptions not supported by laboratory data, and prolonged treatment courses. Our results identify factors that can be used to support UTI treatment pathways and ensure antibiotic stewardship.

6634 Dual-Mediated PTH And Osteolytic Hypercalcemia In Metastatic Endometrial Carcinoma

Abstract Disclosure: C.K. Persaud: None. D.J. Beckman: None. Background: Hypercalcemia of malignancy occurs in 20-30% of advanced stage cancer patients. Etiologies include parathyroid hormone-related peptides (PTHrP)-mediated, osteolytic metastases-mediated, overproduction of 1,25-dihydroxycholecalciferol, and rarely parathyroid hormone (PTH)-mediated. PTH-mediated hypercalcemia of malignancy is rare and occurs through ectopic PTH production or primary hyperparathyroidism. We report a rare case of both PTH-mediated and osteolytic-mediated hypercalcemia in the setting of malignancy. Clinical Case: A 57-year-old female with history of endometrial cancer and multiple solid organ metastasis, presented with two weeks of progressive poor oral intake, nausea, emesis, and right flank pain. On hospital admission, she had a serum calcium of &amp;gt;20.1 mg/dL (8.6-10.2), PTH of 203 pg/mL (15.0-65.0), and creatinine of 1.7 mg/dL (0.7-1.2, baseline 1.3). Non-contrasted CT chest/abdomen/pelvis noted increased size of known right adrenal metastasis, new left adrenal metastasis, periaortic lymphadenopathy, and scattered nodules in the subcutaneous tissues of the abdomen and chest, however bone metastasis were not noted. Patient’s hypercalcemia was treated with zoledronic acid, calcitonin, cinacalcet, and eventually denosumab due to difficulty controlling hypercalcemia. Additional labs obtained during evaluation included ionized calcium &amp;gt;2.5 nmol/L (1.12-1.32), PTHrP &amp;lt;2.0 pmol/L (&amp;lt;2.0), 1,25-dihydroxycholecalciferol &amp;lt;10 pg/mL (21-65). Patient’s right adrenal metastasis biopsy one month prior to admission was subsequently stained for PTH and was negative. Technetium-99m sestamibi scan was obtained for localization of parathyroid adenoma or carcinoma. The scan did not localize, however did show numerous new lytic lesions in the skull, spine, sternum, rib cage, and right humerus. Patient’s hospital course was complicated by progressively worsening renal function, anemia, and thrombocytopenia. Patient was discharged to a long-term acute rehab facility off hypercalcemia treatment with a corrected calcium of 10.0 mg/dL. Conclusion: PTH-mediated hypercalcemia is a rare cause of hypercalcemia of malignancy. PTH levels are typically low or low-normal in osteolytic mediated hypercalcemia. Generally, if PTH is elevated in hypercalcemia, an alternate etiology is not evaluated. This case highlights a rare dual-mediated hypercalcemia of malignancy. The patient’s PTH level elevation was discordant with her high degree of hypercalcemia and prolonged treatment course. She was subsequently found to have widespread bone metastases contributing to hypercalcemia. While multiple etiologies of hypercalcemia can be rare, it is important to evaluate for all contributing causes, especially with additional clinical conditions, such as malignancy.

Innovating Leishmaniasis Treatment: A Critical Chemist's Review of Inorganic Nanomaterials.

Leishmaniasis, a critical Neglected Tropical Disease caused by Leishmania protozoa, represents a significant global health risk, particularly in resource-limited regions. Conventional treatments are effective but suffer from serious limitations, such as toxicity, prolonged treatment courses, and rising drug resistance. Herein, we highlight the potential of inorganic nanomaterials as an innovative approach to enhance Leishmaniasis therapy, aligning with the One Health concept by considering these treatments' environmental, veterinary, and public health impacts. By leveraging the adjustable properties of these nanomaterials─including size, shape, and surface charge, tailored treatments for various diseases can be developed that are less harmful to the environment and nontarget species. We review recent advances in metal-, oxide-, and carbon-based nanomaterials for combating Leishmaniasis, examining their mechanisms of action and their dual use as standalone treatments or drug delivery systems. Our analysis highlights a promising yet underexplored frontier in employing these materials for more holistic and effective disease management.

Clinical characteristics and prognosis of liver injury induced by immune checkpoint inhibitors in patients with malignancies: A real-world retrospective study.

Programmed cell death receptor (ligand)-1 inhibitors (PD-(L)1), as the preferred immunotherapy, have been widely used in the Chinese mainland and drug-induced liver injury (DILI) has been reported. The study aimed to investigate the clinical features or risk factors for immunotherapy-related DILI. Patients who received PD-(L)1 inhibitors from January 2020 to July 2021 were retrospectively reviewed. The likelihood of DILI was adjudicated by the Roussel-Uclaf causality assessment. A total of 1175 patients were included in the study and 89 patients (7.6%) developed DILI, of which 12 (13.5%) progressed to acute liver failure (ALF) and three (3.4%) died. Among the DILI population, 56 (62.9%) had a cholestatic pattern and exhibited a prolonged treatment course and duration for resolution compared to the hepatocellular and mixed patterns. Hepatocellular carcinoma (HCC), hepatitis B virus (HBV) and abnormal baseline of alkaline phosphatase (ALP) had increased risks of DILI by 2.1-fold (95% confidence interval [CI], 1.231-3.621), 1.9-fold [95% CI, 1.123-3.325] and 2.1-fold [95% CI, 1.317-3.508], respectively. The model for end-stage liver disease (MELD) score had a c-statistic of 0.894 (95% CI, 0.778-1.000) with a sensitivity of 67% and a specificity of 95% for poor outcomes. COX analysis showed that the MELD ≥ 18 was predictive of immunotherapy-related ALF or death. PD-(L)1 inhibitor-related liver injury manifests primarily as a cholestatic pattern, on which corticosteroid treatment has minimal effect compared to hepatocellular and mixed patterns. MELD score ≥ 18 at the time of liver injury performed best in the prediction of ALF or death in immune checkpoint inhibitor (ICI)-related DILI.

An International, Multicenter Feasibility Study on Active and Continuous Irrigation With Cerebrospinal Fluid Exchange for Improving Outcomes in Cerebral Ventriculitis.

Cerebral ventriculitis remains a challenging neurosurgical condition because of poor outcomes including mortality rates of nearly 80% and a prolonged course of treatment in survivors. Despite current conventional management, outcomes in some cases remain unsatisfactory, with no definitive therapeutic guidelines. This feasibility study aims to explore the use of a novel active, continuous irrigation and drainage system (IRRAflow [IRRAS AB]) combined with intraventricular drug delivery for patients with cerebral ventriculitis. We conducted a multicenter, international, retrospective study of patients with ventriculitis who were treated with use of the IRRAflow system. Data collected included patient demographics, comorbidities, admission Glasgow Coma Scale score, baseline modified Rankin Scale (mRS) score, and imaging findings. Catheter occlusions, infections, and shunt placement were recorded for outcome assessment, along with discharge mRS scores and in-hospital deaths. Four centers contributed data for a total of 21 patients who had IRRAflow placement for treatment of ventriculitis. Thirteen (61.9%) were men (mean age = 49.8 ± 14.87 years). The median baseline mRS score was 1. The median Glasgow Coma Scale score at admission was 13. The etiology of ventriculitis was iatrogenic in 12 (57.1%) patients and secondary to an abscess in 9 (42.9%). No cases reported hemorrhage or failure of IRRAflow placement. Antibiotics were administered through the IRRAflow system in 13 (61.9%) cases in addition to systemic dosing. Sixteen (76.2%) patients had significant clinical improvement and resolution of ventriculitis. Seven (33.3%) patients required shunt placement after resolution because of persistent hydrocephalus. There were 6 (28.6%) in-hospital deaths. The use of active irrigation with drainage for continuous delivery of intraventricular irrigation fluid with antibiotics led to dramatically low mortality. In our case series, it led to a marked improvement in neurological status, imaging findings, and cerebrospinal fluid profiles, making it a technically feasible and safe treatment for ventriculitis.

Financial Toxicity Among Patients With Metastatic Prostate Cancer: A Mixed Methods Approach to Identify Effective Interventions.

Financial toxicity associated with treatments for metastatic prostate cancer remains poorly defined. We sought to understand aspects of financial toxicity not captured in a commonly employed financial toxicity questionnaire and identify potential interventions to help alleviate financial toxicity through a convergent mixed methods approach. Patients seen at our institution's advanced prostate cancer clinic were approached for completion of the Comprehensive Score for Financial Toxicity (COST-FACIT) questionnaire (quantitative analysis). A maximal variation purposive sample was chosen to participate in focus group discussions (qualitative analysis). Conventional content analysis was performed using an inductive approach. COST-FACIT scores were compared between patients experiencing high and low financial toxicity using Wilcoxon rank sum test. Three themes were identified through qualitative analysis: (1) workload, (2) coping strategies, and (3) communication. We found alignment with the existing theory of financial capacity across our findings. Two unique aspects of financial toxicity emerged that were not assessed quantitatively and deemed to be significant. Specifically, cost transparency (including health care teams knowledgeable about and willing to discuss costs) and inclusion of informal caregivers in financial toxicity screening and decision-making may guide future interventions aimed at limiting financial toxicity in this population. Prolonged treatment courses involving multiple lines of treatment with varying costs result in distinct financial toxicity components for patients with metastatic prostate cancer that are not assessed with COST-FACIT. Improving cost transparency, health care team knowledge and engagement, and providing resources to support informal caregivers may have a significant impact on the financial toxicity experienced by these patients.

Depressive symptom trajectories with prolonged rTMS treatment

BackgroundA prolonged repetitive transcranial magnetic stimulation (rTMS) treatment course could be beneficial for some patients experiencing major depressive episodes (MDE). We identified trajectories of rTMS response in depressive patients who received an extended rTMS treatment course and sought to determine which trajectories achieved the greatest benefit with a prolonged treatment course. MethodWe applied group-based trajectory modeling to a naturalistic dataset of depressive patients receiving a prolonged course of sequential bilateral rTMS (up to 51 treatment sessions) to the dorsolateral prefrontal cortex. Trajectories of the PHQ-9 with extended treatment courses were characterized, and we explored the association between baseline clinical characteristics and group membership using multinomial logistic regression. ResultsAmong the 324 study participants, four trajectories were identified: “linear response, extended course” (N = 73; 22.5 %); “nonresponse” (N = 23; 7.1 %); “slowed response” (N = 159; 49.1 %); “rapid response, standard treatment length” (N = 69; 21.3 %). Only the “linear response, extended course” group showed considerable clinical improvement after receiving additional rTMS treatments. Greater baseline depressive symptoms were associated with linear response and non-response. ConclusionOur results confirmed the distinctive response trajectories in depressive patients receiving rTMS and further highlighted that prolonged rTMS treatment courses may be beneficial for a subset of patients with higher initial symptom levels and linear early treatment response.

Evaluation of the effect of therapeutic durations on small ruminant bacterial pneumonia

BackgroundSheep and goat production in Ethiopia is hindered by numerous substandard production systems and various diseases. Respiratory disease complexes (RDC) pose a significant threat to the productivity of these animals. Pneumonia is a common manifestation of respiratory disease complexes and often necessitates a prolonged course of antibiotic treatment. This study aimed to optimize and propose the ideal duration of therapy for pneumonia in sheep and goats.MethodsThe study was conducted from February to June 2021 at the Veterinary Teaching Hospital of the College of Veterinary Medicine and Agriculture, Addis Ababa University. The study recruited 54 sheep and goats presented to the hospital for treatment with a confirmed RDC as determined based on clinical signs and bacteriological methods. The animals were randomly allocated to 5 groups each group receiving 10% oxytetracycline (Phenxyl, Phenix, Belgum) intramuscularly for a duration of 3, 4, 5, 6 and 7 consecutive days. The treatment outcomes were assessed by recording vital signs (body temperature, respiratory rate, heart rate, coughing, and nasal discharges), performing lung ultrasonography (L-USG) as well as collection of nasal swabs for bacterial isolation and molecular identification before and after completion of the treatment. An ordered logistic regression model with random effects was employed to determine the optimal therapeutic duration, taking into account the cumulative scores of the outcome variables across the different groups.ResultsAmong the 54 sheep and goats treated with 10% oxytetracycline, a total of 74.07% (95% CI, 60.35–85.04) achieved complete recovery, as confirmed through clinical, ultrasound, and bacteriological methods. In Group 1 (G1), out of 12 sheep and goats, 8 (83.0%) recovered completely; in Group 2 (G2), out of 11 animals, 9 (82.0%) recovered completely; in Group 3 (G3), out of 11 animals, 10 (93.0%) recovered completely; in Group 4 (G4), out of 9 animals, 9 (100.0%) recovered completely; and in Group 5 (G5), out of 11 animals, 10 (91.0%) recovered completely. Bacteriological examination of nasal swabs indicated involvement of M. hemolytica in 27 (50.00%) and P. multocida in 13 (24.07%) of pneumonic animals. Detection of specific marker genes confirmed only five of the presumptive M. hemolytica isolates, whilst no isolates tested positive for P. multocida. Post-treatment samples collected from recovered animals did not yield any M. hemolytica nor P. multocida. Based on results from clinical signs, L-USG, and bacterial infection variables, the group of sheep and goats treated for seven consecutive days (G5) showed the highest recovery score compared to the other groups, and there was a statistically significant difference (coefficient (β) = − 2.296, p = 0.021) in variable score between G5 and G1. These findings suggest that the administration of 10% oxytetracycline for a full course of seven consecutive days resulted in symptomatic and clinical recovery rates from respiratory disease in sheep and goats.

Isolated first metatarsal tubercular osteomyelitis of the foot in a boy: A case report with review of literature

Isolated tubercular lesions of the metatarsal bones are rare, with an incidence of less than 0.5%. Because of ambiguous signs and symptoms, and reasonably normal laboratory investigations, these lesions pose a diagnostic challenge and there are chances of misinterpretation of radiographic images. We present a case of tubercular osteomyelitis of the first metatarsal of right foot in a 9-year-old boy. The diagnosis was initially made using plain X-ray, which was supported by magnetic resonance imaging and confirmed by the histopathological examination of the resected samples and microbiological culture combined with polymerase chain reaction. The patient was managed with open biopsy and curettage followed by a prolonged course of anti-tubercular treatment. The patient showed complete resolution of symptoms with no sign of recurrence.

Incidence of amoxycillin-clavulanic acid associated hepatotoxicity in an Australian children's hospital.

Amoxycillin/clavulanic acid is the most common antimicrobial cause of drug-induced liver injury in adults. It is a less common cause of severe drug-related hepatotoxicity in children despite its frequent use. We studied the incidence, characteristics and predictive factors for amoxycillin/clavulanic acid hepatoxicity in children. Retrospective cohort study of children who received oral or intravenous amoxycillin/clavulanic acid at a quaternary children's hospital over a 5-year period. Children were included if they had liver function tests (LFTs) determined at baseline, during and within 3 months after the treatment course. Causality was assessed using the Naranjo criteria for adverse drug reactions and Roussel Uclaf Causality Assessment Method. Of 3271 children prescribed amoxycillin/clavulanic acid, 374 were included. Forty-nine (13%) had LFT abnormalities related to amoxycillin/clavulanic acid. Fourteen (3.6%) fulfilled Common Terminology Criteria for Adverse Events (CTCAE) grade 2 criteria with clinically significant hepatotoxicity. Age <2 years, sepsis, post-gastrointestinal surgical indications, prolonged treatment course of >7 days and higher cumulative amoxycillin (>10 g) and clavulanic acid dose (>1 g) were predictive of hepatotoxicity. The median time to resolution of LFT abnormalities was 4 weeks (range 3-7). The incidence of amoxycillin/clavulanic acid related LFT abnormalities (CTCAE Grade 2 or above) in children was 3.6%. A prolonged treatment course >7 days, high cumulative amoxycillin (10 g) and clavulanic acid (>1 g) doses, those aged <2 years, and patients with sepsis or post-gastrointestinal surgery were predictive of a higher likelihood of abnormal LFTs. LFT monitoring should be considered in children receiving ≥7 days of treatment, particularly in those with other predisposing factors.

Pulmonary Thromboembolism in Multidrug-Resistant Tuberculosis: A Case Series Highlighting the Importance of Early Diagnosis and Management

Background: Pulmonary tuberculosis (PTB) is an established cause of arterial and venous thrombosis. With the rising incidence of multidrug-resistant tuberculosis (MDR TB), which has a prolonged treatment course, pulmonary thromboembolism in such cases further complicates the treatment outcome in terms of mortality and morbidity. TB causes systemic hypercoagulability, which may lead to both arterial and venous thrombosis. Therefore, it is important for treating physicians to be aware of the entity and have a sharp watch for the development of Pulmonary thromboembolism in cases of MDR TB. The Case: We present the association of pulmonary thromboembolism (PTE) with MDR TB in three young males who developed pulmonary thromboembolism during the treatment of MDR TB, along with their management using anticoagulant agents. Conclusion: PTE in cases of TB is rare but fatal. High suspicion of PTE in patients with MDR TB will help in diagnosing the dreaded condition early and aid in reducing preventable mortality with PTE. Early recognition, prompt diagnosis, and management is the key to saving the lives of those with this fatal complication.

Sociodemographic versus clinical factors associated with incomplete and prolonged courses of radiotherapy.

139 Background: Radiotherapy is an important component of therapy for many patients with cancer. However, some patients have difficulty completing recommended courses of radiotherapy in a timely manner. Unfortunately, prolonged or incomplete courses of therapy are associated with higher rates of relapse and lower survival rates, particularly for head and neck and cervical cancers. However, the most important drivers of incomplete or prolonged treatment courses are unclear. Our objective was to quantify associations between sociodemographic and clinical factors and incomplete and prolonged treatment courses. Methods: We extracted data for all patients treated with radiotherapy at a large metropolitan academic institution from 2018 – 2022 from the radiotherapy treatment planning software and from the medical record. Incomplete radiotherapy courses were defined as lack of completion of all planned radiotherapy fractions based on the treating physician’s prescription. Prolonged radiotherapy courses were defined as prolonging treatment by more than 5 days and missing 5 or more fractions, a clinically meaningful delay that can impact cancer outcomes. The primary endpoint was a composite endpoint consisting of incomplete and prolonged radiotherapy courses. Multivariable logistic regression was utilized to quantify associations between incomplete and prolonged treatment courses with age, sex, distance to facility, ZIP code social deprivation index (SDI), insurance status, radiotherapy modality, number of radiotherapy fractions, and treatment site. Models were also adjusted for year-quarter. Results: A total of 9950 cases were included, including 352 (6.5%) and 642 (3.5%) incomplete and incomplete/prolonged radiotherapy courses, respectively. In multivariable logistic regression analyses, factors associated with increased risk of incomplete or prolonged radiotherapy courses included ZIP code SDI &gt; 80 (8.8%, OR 1.43, 95% CI = 1.13-1.80, P=.003), Medicaid insurance (12%, OR 1.92, 1.47-2.50, P&lt;.001), more than 5 fractions of radiotherapy (12.8%, 9.7%, 14.6%, and 13.1%, for 6-10, 11-20, 21-29, 30+ fractions, respectively; P&lt;.001), and treatment site of female pelvis (23.9%, OR 3.27, 2.26-4.78, P&lt;.001). Conclusions: Prolonged or incomplete radiotherapy courses were associated with disadvantaged neighborhoods, Medicaid insurance, higher number of radiotherapy fractions, and female pelvic cancers. Each of these factors is related to social determinants of health and time/financial burden of treatment, including female pelvic cancers (predominantly locally advanced cervical cancer, associated with lower socioeconomic status), underscoring the impact of social determinants of health on patient’s ability to undergo radiotherapy.

Ferric derisomaltose and Outcomes in the Recovery of Gynecologic oncology: ERAS (Enhanced Recovery After Surgery) (FORGE) – a protocol for a pilot randomised double-blinded parallel-group placebo-controlled study of the feasibility and efficacy of intravenous ferric derisomaltose to correct preoperative iron-deficiency anaemia in patients undergoing gynaecological oncology surgery

IntroductionIron-deficiency anaemia is common in gynaecological oncology patients. Blood transfusions are immunosuppressive and carry immediate and long-term risks. Oral iron replacement remains the standard of care but requires prolonged treatment...

Screening for latent infectious disease in patients with alopecia areata before initiating JAK inhibitors therapy: a single-center real-world retrospective study.

Although there is growing evidence supporting the effectiveness of Janus kinase (JAK) inhibitors in treating alopecia areata, the high rate of recurrence following drug discontinuation has led to prolonged treatment courses and raised concerns about long-term safety. In clinical practice, caution should be exercised while using JAK inhibitors for various indications, and a comprehensive pre-treatment screening. This study presents an analysis of screening data collected from real-world settings before the initiation of Janus kinase inhibitors in patients with alopecia areata. Investigators collected retrospective medical data characterizing patients' screening data. Data on demographic and clinical data, including age, sex, disease duration, severity of alopecia tool scale, history of prior treatment, and treatment regimen were recorded. In this cohort (N = 218), JAK inhibitors were initiated for 163 of 218 (74.8%) alopecia areata patients. The numbers of patients positive for antinuclear antibodies, hepatitis B surface antigen, hepatitis C virus antibodies, human immunodeficiency virus antibody, treponema pallidum hemagglutination assay, and thyroid-stimulating hormone were 32 (32/176), 10(10/218), 0 (0/218), 0 (0/218), 3 (3/218) and 9 (9/176), respectively. The number of patients with T-cell spot positive or imaging of the chest indicating tuberculosis was 37 (37/218). Our data provide additional information on the safety profile of JAK inhibitors in patients with alopecia areata. As such, it is necessary and crucial to screen for JAK inhibitors before it is used, particularly for individuals with a high risk of tuberculosis, hepatitis B, and other infections.

Microbiome of infected fracture nonunion: Does it affect outcomes?

BackgroundInfected fracture nonunions often require prolonged treatment and recovery courses. It is unclear whether the bacterial microbiome influences the time to healing as well as the eradication of infection. The goals of this study are (1) to assess the bacterial microbiome affecting infected nonunions and (2) to evaluate the effects of bacterial speciation on associated outcomes. MethodsBetween 2006 and 2022, data from 551 adult patients from a single academic institution who presented with a fracture nonunion were analyzed retrospectively for infection. All patients underwent revision surgery with three sets of cultures obtained intra-operatively. Patients with significant intra-operative cultures were grouped into gram-positive and gram-negative culture cohorts. These patients were managed with a standardized protocol involving surgical debridement, nonunion site fixation, and culture-directed antibiotic treatment. Primary outcome was time to fracture union. Secondary outcomes included number of re-operations and eventual amputation or reconstructive surgery. Results56 nonunion patients (10 %) were diagnosed with an infected nonunion (44 g-positive, 12 g-negative). Of these, 3 g-positive patients received an amputation or arthroplasty procedure prior to fracture union, and seven were lost to follow-up. There were no significant differences in age, gender, or nonunion site between cohorts. Most nonunions occurred in the lower extremity. The most common bacteria were staph species (54.3 %). 36 g-positive and 10 g-negative patients achieved fracture union. Time to union was on average 158.4 days longer in the gram-negative cohort—but did not reach statistical significance (446.8 days gram-positive, 662.3 days gram-negative, p = 0.69). There was no difference in re-operation rates (1.9 % gram-positive, 2.2 % gram-negative, p = 0.84). ConclusionsPatients with infected nonunions had wide-ranging bacterial contamination that were treated successfully using a standardized protocol. However, patients with any gram-negative culture trended toward a delay in time to union.

Determinants of appointment nonattendance among outpatients with hidradenitis suppurativa

AbstractBackgroundHidradenitis suppurativa (HS) is associated with several comorbidities and significant impairment of quality of life. Moderate to severe HS patients have often prolonged treatment courses at various hospitals. We investigated various factors that may be related to missed follow‐up visits during prolonged treatment courses among HS outpatients.ObjectivesTo highlight potential predictors for appointment absenteeism among HS patients.MethodsDuring a 12‐month period at a university hospital dermatology outpatient clinic, absenteeism and related factors were obtained for each visit at the hospital.ResultsOut of 161 unique follow‐up visits during a 12‐month period at a university hospital dermatology outpatient clinic, 37 patients (23.0%) were absentees. Patients with non‐attendance were more likely to be males (p = 0.02). Patients who were on biologic treatment for HS were less likely to miss appointments (p = 0.06).ConclusionsOur study showed that almost one in four hospital outpatients with HS fail to show up for their scheduled appointments. The data suggest an increased awareness of high risk of missed follow‐up visits during treatment of HS patients.

Steroid-Dependent Nephrotic Syndrome in a Child After an Allogeneic Bone Marrow Transplant: A Case Report

Nephrotic syndrome is a frequently encountered disease in children. It is mostly responsive to high-dose steroids, with some requiring steroid-sparing immunosuppressive regimens, or further, a renal biopsy if resistant to steroid therapy. However, nephrotic syndrome in children post-allogeneic bone marrow transplant is rarely encountered. The authors report here a child who developed nephrotic syndrome post-allogeneic bone marrow transplant for β-thalassaemia major, with the suspicion of graft-versus-host disease that was difficult-to-treat, who had frequent relapses with multiple hospital admissions, and prolonged treatment course. For the last 5 years, the disease has been in remission, on a low dose of prednisolone and mycophenolate mofetil-based maintenance immunosuppressive treatment.
