RESUMO

Large defects on the face after Mohs surgery have posed significant reconstructive challenges. A 90-year-old man presented with melanoma in situ of the central forehead, which resulted in a 4.5cmx4.3cm defect after multiple stages of Mohs surgery. Although different approaches for forehead repair with nasal root involvement are possible, we demonstrate that the V-Y advancement flap and subsequent Burrow graft for nasal root repair represents a viable closure technique for large circular defects of the central forehead.

RESUMO

Workers, particularly outdoor workers, are among the populations most disproportionately affected by climate-related hazards. However, scientific research and control actions to comprehensively address these hazards are notably absent. To assess this absence, a seven-category framework was developed in 2009 to characterize the scientific literature published from 1988-2008. Using this framework, a second assessment examined the literature published through 2014, and the current one examines literature from 2014-2021. The objectives were to present literature that updates the framework and related topics and increases awareness of the role of climate change in occupational safety and health. In general, there is substantial literature on worker hazards related to ambient temperatures, biological hazards, and extreme weather but less on air pollution, ultraviolet radiation, industrial transitions, and the built environment. There is growing literature on mental health and health equity issues related to climate change, but much more research is needed. The socioeconomic impacts of climate change also require more research. This study illustrates that workers are experiencing increased morbidity and mortality related to climate change. In all areas of climate-related worker risk, including geoengineering, research is needed on the causality and prevalence of hazards, along with surveillance to identify, and interventions for hazard prevention and control.

RESUMO

Eccrine angiomatous hamartoma is an uncommon, benign clinical entity constituting a nodular proliferation of eccrine glands and vascular structures localized to the dermis that typically present as unilateral, flesh-colored, erythematous, or violaceous papules on the extremities. These hamartomas may be associated with pain, hyperhidrosis, joint deformity, or functional impairment depending on the severity of the disease process. We present a case of bilaterally symmetric, asymptomatic eccrine angiomatous hamartomas involving all proximal interphalangeal joints of both hands. To date, there are only four prior cases of bilaterally symmetric eccrine angiomatous hamartomas reported in the literature, suggesting that the distribution experienced by our patient may represent a previously undescribed syndrome.

RESUMO

PURPOSE OF REVIEW: We review recent evidence on the use of neuromodulation for treating eating disorders (EDs), including anorexia nervosa, bulimia nervosa and binge eating disorder. We evaluate studies on (a) modern non-invasive methods of brain stimulation, such as transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), (b) electroconvulsive therapy (ECT) and (c) more invasive techniques, including deep brain stimulation (DBS). RECENT FINDINGS: Most reports on the clinical applications of neuromodulation in EDs are limited to case studies, case series and small clinical trials. The majority have focused on severe, enduring and hard-to-treat cases of AN. In this population, data suggest that both rTMS and DBS have therapeutic potential and are safe and acceptable. High-quality clinical trials in different ED populations are needed which investigate different stimulation methods, sites and parameters, the use of neuromodulation as stand-alone and/or adjunctive treatment, as well as the mechanisms of action.

RESUMO

NSI-189 is a novel neurogenic compound independent of monoamine reuptake pathways. This trial evaluated oral NSI-189 as monotherapy in major depressive disorder. To improve signal detection, the sequential-parallel comparison design (SPCD) was chosen. Two hundred and twenty subjects were randomized to NSI-189 40 mg daily, 80 mg daily, or placebo for 12 weeks. The primary outcome measure was the Montogmery Asberg Depression Rating Scale (MADRS). Secondary subject-rated measures included the Symptoms of Depression Questionnaire (SDQ), the Cognitive and Physical Functioning Scale (CPFQ), the patient-rated version of the Quick Inventory of Depressive Symptomatology Scale (QIDS-SR), and subtests from the CogScreen and Cogstate cognitive tests. MADRS score reduction versus placebo did not reach significance for either dose (40 mg pooled mean difference -1.8, p = 0.22, 80 mg pooled mean difference -1.4, p = 0.34, respectively). However, the 40 mg dose showed greater overall reduction in SDQ (pooled mean difference -8.2; Cohen's d for Stages 1 and 2 = -0.11 and -0.64, p = 0.04), and CPFQ scores (pooled mean difference -1.9; Cohen's d for Stages 1 and 2 = -0.28 and -0.47, p = 0.03) versus placebo, as well as QIDS-SR scores in Stage 2 of SPCD (-2.5; Cohen's d Stages 1 and 2 = -0.03 and -0.68, p = 0.04). The 40 mg dose also showed advantages on some objective cognitive measures of the CogScreen (absolute Cohen's d ranged between 0.12 and 1.12 in favor of NSI-189, p values between 0.002 and 0.048 for those with overall significance), but not the Cogstate test. Both doses were well tolerated. These findings replicate those of phase 1b study, and warrant further exploration of the antidepressant and pro-cognitive effects of NSI-189.

RESUMO

Guidelines recommend that women take folic acid supplements in the preconception period to prevent neural tube defects (NTDs) in their offspring. Estimates of adherence to this recommendation across different countries worldwide have not been synthesized. Medline, CINAHL, and EMBASE were systematically searched to identify studies reporting the prevalence of preconception folic acid supplementation. Pooled prevalence estimates for each country (where data were available) were calculated; and differences based on demographic, methodological, and study quality characteristics were examined. Of 3372 titles and abstracts screened, 722 full-texts were reviewed and 105 articles that reported 106 estimates of preconception folic acid supplementation in 34 countries were included. Pooled prevalence estimates were 32-51% in North America, 9-78% in Europe, 21-46% in Asia, 4-34% in the Middle East, 32-39% in Australia/New Zealand, and 0% in Africa. No South American studies were identified. Higher supplementation prevalence was observed in studies that had more highly educated samples, were conducted in fertility clinics, and assessed folic acid use via self-report. Of note, only 32% and 28% of studies reported timing of folic acid use and adherence to folic acid, respectively. Preconception folic acid supplementation is highly variable worldwide and many women may not achieve sufficient folate levels to prevent NTDs. To better understand non-adherence, recommendations for future research include: more explicit reporting of methodology, more detailed assessment of folic acid use, assessment of variables potentially relevant to folic acid use, and surveillance of folic acid use in a greater diversity of countries, especially in the developing world.

RESUMO

BACKGROUND: Lurbinectedin (PM01183) has synergistic antitumor activity when combined with doxorubicin in mice with xenografted tumors. This phase I trial determined the recommended dose (RD) of doxorubicin (bolus) and PM01183 (1-h intravenous infusion) on day 1 every 3 weeks (q3wk), and obtained preliminary evidence of antitumor activity for this combination in small-cell lung cancer (SCLC). PATIENTS AND METHODS: Patients with advanced solid tumors received doxorubicin and PM01183 following a standard dose escalation design and expansion at the RD. Twenty-seven patients had relapsed SCLC: 12 with sensitive disease (platinum-free interval ≥90 days) and 15 with resistant disease (platinum-free interval <90 days). RESULTS: Doxorubicin 50 mg/m2 and PM01183 4.0 mg flat dose was the RD. In relapsed SCLC, treatment tolerance at the RD was manageable. Transient and reversible myelosuppression (including neutropenia, thrombocytopenia, and febrile neutropenia) was the main toxicity, managed with dose adjustment and colony-stimulating factors. Fatigue (79%), nausea/vomiting (58%), decreased appetite (53%), mucositis (53%), alopecia (42%), diarrhea/constipation (42%), and asymptomatic creatinine (68%) and transaminase increases (alanine aminotransferase 42%; aspartate aminotransferase 32%) were common, and mostly mild or moderate. Complete (n = 2, 8%) and partial response (n = 13, 50%) occurred in relapsed SCLC, mostly at the RD. Response rates at second line were 91.7% in sensitive disease [median progression-free survival (PFS)=5.8 months] and 33.3% in resistant disease (median PFS = 3.5 months). At third line, response rate was 20.0% (median PFS = 1.2 months), all in resistant disease. CONCLUSION: Doxorubicin 50 mg/m2 and PM01183 4.0 mg flat dose on day 1 q3wk has shown remarkable activity, mainly in second line, with manageable tolerance in relapsed SCLC, leading to further evaluation of this combination within an ongoing phase III trial.

RESUMO

We wanted to examine tolerability and efficacy of NSI-189, a benzylpiperizine-aminiopyridine neurogenic compound for treating major depressive disorder (MDD). This was a Phase 1B, double blind, randomized, placebo controlled, multiple-dose study with three cohorts. The first cohort received 40 mg q.d. (n=6) or placebo (n=2), the second cohort 40 mg b.i.d. (n=6) or placebo (n=2), and the third cohort 40 mg t.i.d. (n=6) or placebo (n=2). Twenty-four patients with MDD were recruited, with the diagnosis and severity confirmed through remote interviews. Eligible patients received NSI-189 or placebo for 28 days in an inpatient setting with assessments for safety, pharmacokinetics (PK) and efficacy. Outpatient follow-up visits were conducted until day 84 (±3). NSI-189 was relatively well tolerated at all doses, with no serious adverse effects. NSI-189 area under the curve increased in a dose-related and nearly proportional manner across the three cohorts, with a half-life of 17.4-20.5 h. The exploratory efficacy measurements, including Symptoms Of Depression Questionnaire (SDQ), Montgomery-Asberg Depression Scale (MADRS), Clinical Global Impressions-Improvement (CGI-I), and The Massachusetts General Hospital (MGH) Cognitive and Physical Functioning Questionnaire (CPFQ) showed a promising reduction in depressive and cognitive symptoms across all measures for NSI-189, with significant improvement in the SDQ and CPFQ, and a medium to large effect size for all measures. These improvements persisted during the follow-up phase. In summary, NSI-189 shows potential as a treatment for MDD in an early phase study. The main limitation of this preliminary study was the small sample size of each cohort.

RESUMO

UNLABELLED: Introduction E7820 is an orally administered sulfonamide that inhibits alfa-2-integrin mRNA expression. Pre-clinically E7820 showed tumor anti-angiogenic effects in various tumor cell lines and xenograft mouse models. Human daily dosing of 100 mg QD had previously been shown to be safe and tolerable. Methods The study consisted of two parts: Part A (food effect) and Part B (determination of maximum tolerated dose (MTD) for bi-daily (BID) dosing). E7820 dosing started at 50 mg BID with planned escalation to 60, 80 and 100 mg BID every 28 days. Results Fifteen patients were enrolled in Part A and 26 in Part B. The most frequent adverse events of all grades were constipation, diarrhea, nausea, and fatigue while anemia, neutropenia, and fatigue were most frequent grade ≥3 toxicities. At dose-level 60 mg BID, two patients experienced dose-limiting toxicities (grade 3 neutropenic sepsis and grade 4 neutropenia). Therefore the recommended dose (RD) was 50 mg BID. Food had no effect on E7820 exposure. E7820 exposure following twice daily administration was dose-proportional. Expression of platelet integrin-α2 measured as a response biomarker in Part B, generally decreased by a median 7.7 % from baseline following treatment with 50 mg BID E7820. Reduction was most pronounced within 1-week post treatment. The median duration of treatment was median 54, range 20-111 days. The best overall response in any treatment group was stable disease (SD): 23.1 % in Part A (100 mg QD); at the RD 66.7 % (12 of 18 patients) and 40 % in the 60 mg BID group in Part B. CONCLUSIONS: Food had no effect on E7820 exposure. A dose of 50 mg BID was considered the MTD. Treatment with E7820 is safe and tolerable with 2/3 of patients (66.7 %) at MTD having SD as their best response.

RESUMO

OBJECTIVES: Variability in Baha® sound processor fittings arise from several sources including the nature of the implant-to-bone transmission and transcranial attenuation in patients with single-sided sensorineural deafness. One method of improving the predictability of Baha fittings is to measure the individual patient's actual bone conduction thresholds via the implant, thereby removing the influence of skin thickness and/or implant location site. METHODOLOGY: One hundred thirty eight adult wearers of the Baha System participated in the study. Direct bone conduction thresholds were obtained through the BC Direct feature of the Cochlear™ Baha Fitting Software combined with the CochlearBaha BP100 sound processor. Test-retest reliability measurement was performed in 58 participants. RESULTS: Improved transmission of sound through the implant rather than transcutaneously through the skin was confirmed. On average, the BC Direct thresholds were closer to the patient's unmasked thresholds than the masked values. In patients with single-sided sensorineural deafness, BC Direct results were elevated compared to the contralateral bone conduction thresholds due to transcranial attenuation. The test-retest reliability for the BC Direct measurements was within ±5 dB, which is in within the accepted variability for audiometric test measurements. CONCLUSIONS: Direct bone conduction measurement provides a validated method of comparing the transcutaneous thresholds as measured through audiometry with the percutaneous responses from the Baha sound processor. The Baha fitting based on direct measurements of bone conduction may require less fine-tuning and provide a greater understanding of the variability of the bone conduction sound pathway.

RESUMO

PURPOSE: Supporting someone through chemotherapy can be emotionally and physically demanding. However, research has yet to establish the type of support carers require or the best way to provide this. This study tested the feasibility and acceptability of a complex intervention for carers that was co-designed by staff and carers of patients starting chemotherapy. METHODS: Forty-seven carers were recruited, randomised between the intervention (n = 24) and control (n = 23) groups. A questionnaire was completed pre- and post-intervention measuring knowledge of chemotherapy and its side effects, experience of care, satisfaction with outpatient services, coping and emotional wellbeing. The intervention process was evaluated by carers and healthcare professionals (HCPs) in focus groups. RESULTS: Recruitment to the study was unproblematic and attrition from it was low, suggesting the intervention and study processes were acceptable to patients and carers. Carers in receipt of the 'Take Care' intervention reported statistically significantly better understanding of symptoms and side effects and their information needs being more frequently met than carers in the control. Confidence in coping improved between baseline and follow-up for the intervention group and declined for the control although differences were insufficient to achieve statistical significance. There was no significant difference between the two groups' emotional wellbeing. HCP and carer focus groups confirmed the feasibility and acceptability of the intervention. CONCLUSIONS: The 'Take Care' intervention proved acceptable to carers and HCPs and demonstrates considerable promise and utility in practice. Study findings support the conduct of a fully powered RCT to determine the intervention's effectiveness and cost-effectiveness.

RESUMO

Patients with Parkinson disease (PD) are at high risk for developing melanoma, although current literature lacks details on the associated clinicopathologic characteristics. Our retrospective case-control study aimed to guide skin cancer surveillance recommendations for patients with PD, focusing on tumor sites. Our study included 70 adults with concurrent diagnoses of PD and melanoma from January 1, 2007 to January 1, 2020 at Duke University and 102 age-, sex-, and race-matched controls. The head/neck region accounted for 39.5% of invasive melanomas in the case group compared with 25.3% in the control group as well as 48.7% of noninvasive melanomas in the case group compared with 39.1% in the control group. Of note, 50% of metastatic melanomas in patients with PD originated on the head and neck (n = 3). Logistic regression showed 2.09 times higher odds of having a head/neck melanoma in our case group compared with that in the control group (OR = 2.09, 95% confidence interval = 1.13‒3.86; P = 0.020). Our study is limited by small sample size, and our case cohort lacked diversity regarding race, ethnicity, sex, and geography. Validation of the reported trends could provide more robust guidance for melanoma surveillance in patients with PD.

RESUMO

Weaning--the transition from milk to solid food--influences life-long health. Dietary challenges during weaning include providing sufficient critical nutrients such as iron with minimal added sugar and fat and no added salt. This study assessed the inclusion of iron-containing red meat in infant diets before age one year, and the Irish commercial baby food environment. Of mothers with an infant under 30 months of age who were surveyed in shopping centres in Ireland (n195), 82% (n159) reported wanting more weaning information. A quarter (n24) of infants over age 12 months (n97) received no iron-containing red meat before age one year. A scan of commercial baby foods in Ireland identified 448 products. While all complied with baby food legislation, 15% (n69) were intrinsically high in sugar and fat, or contained added salt. This study indicates the need for specific guidance on best infant feeding practice in Ireland.

RESUMO

Dr Mary T. Martin Sloop and Dr Eustace Henry Sloop shaped the landscape of healthcare and education for the small town of Crossnore in the mountains of Western North Carolina throughout the early- to mid-twentieth century. The duo of general practitioners founded the Crossnore School and the Garrett Memorial Hospital, later renamed Sloop Memorial Hospital before its closure in 1999. The Sloops provided medical care to an underserved Appalachian population and sought advice and assistance from key community stakeholders with every project they undertook, demonstrating their commitment to cultural assimilation. While the story of the Sloop family is one of success, patients in rural America are currently facing a dual crisis of healthcare access. Rural healthcare professional shortages contribute to difficulties establishing longitudinal relationships with primary care providers, which in turn decreases access to preventative medicine services. With over 106 rural hospitals closing since 2010, patients may face travel barriers to reach inpatient facilities with associated emergency services, and access to specialty services such as surgery is diminished. It is paramount to reflect on and learn from the stories of the past, highlighting the personal and professional fulfillment that can be found in embracing rurality through service and community integration.

RESUMO

BACKGROUND: Mastoid exploration remains an advanced, mainstay operation within ENT, in which the surgical trainees' role has been debated. This audit compares mastoid exploration outcomes between trainees and consultants. METHODS: Cortical mastoidectomy, atticotomy, atticoantrostomy, modified radical mastoidectomy, combined-approach tympanoplasty and revision mastoidectomy operations performed between 2009 and 2020 were reviewed. Complications assessed were: facial palsy, labyrinth injury, dead ear, disease recurrence and time to recurrence. The chi-square test was used to determine significant associations. RESULTS: A total of 118 operations were surveyed. Thirty-five per cent of procedures (n = 41) were performed by trainees under supervision, and 65 per cent (n = 77) were carried out solely by consultants. Patients from 5 per cent of trainees' operations (n = 2) developed recurrence, compared with 7.8 per cent of consultants' (n = 6) (p = 0.55). No other complications developed in either group. CONCLUSION: The results corroborate those of other studies, indicating no significant increase in complication rate from consultants to trainees. Trainees likely completed less complicated cases. The stepwise incorporation of trainees did not compromise patient safety.

RESUMO

BACKGROUND: Computed tomography has the potential to inform COPD prognosis. We sought to determine associations of emphysema phenotype with clinical parameters including lung function, inflammatory markers, and quality of life. METHODS: Participants of this single-center observational cohort (n = 83) were 40-80 years old, had ≥10 pack-year smoking, and a diagnosis of COPD confirmed by spirometry. All participants had available historic chest CT scans which were systematically reviewed by a single expert radiologist and scored for emphysema subtype, extent, and distribution. Associations between radiographic findings and clinical parameters were determined. RESULTS: Median age of participants was 72 years, median smoking 40 pack-years, and median FEV1 59% predicted. 84% of the participants had radiographic emphysema. Of those, 26% had panlobular emphysema (PLE), 68% centrilobular emphysema (CLE), and 6% paraseptal emphysema (PSE). As compared to the participants with no radiographic emphysema, the presence of PLE-dominant emphysema was associated with a lower BMI (P = 0.012) and greater extent of emphysema (P = 0.014). After adjusting for age, sex, and pack-years smoking history, PLE was associated with greater airflow obstruction by FEV1% (48% vs 71%, P = 0.005), greater symptom burden by CAT score (18 vs 9, P = 0.015), worse quality of life by SGRQ score (43 vs 22, P = 0.025), and more systemic inflammation by erythrocyte sedimentation rate (P = 0.001). CLE- or PSE-dominant emphysema were not similarly associated with clinical features or symptom burden. CONCLUSIONS: The presence of PLE-dominant emphysema was associated with greater extent of emphysema, greater airflow obstruction, increased respiratory symptoms, worse quality of life, and systemic inflammation. Further investigation is indicated to explore the pathogenesis of the PLE phenotype and the prognostic and treatment implications of PLE.

RESUMO

Importance: Patient-submitted images vary considerably in quality and usefulness. Studies that characterize patient-submitted images in a real-life setting are lacking. Objective: To evaluate the quality and perceived usefulness of patient-submitted images as determined by dermatologists and characterize agreement of their responses. Design, Setting, and Participants: This survey study included patient images submitted to the Department of Dermatology at Duke University (Durham, North Carolina) between August 1, 2018, and December 31, 2019. From a total pool of 1200 images, 10 dermatologists evaluated 200 or 400 images each, with every image being evaluated by 3 dermatologists. Data analysis occurred during the year leading up to the article being written. Main Outcomes and Measures: The primary outcomes were the responses to 2 questions and were analyzed using frequency counts and interrater agreement (Fleiss κ) to assess image quality and perceived usefulness. We performed a random-effects logistic regression model to investigate factors associated with evaluators' decision-making comfort. We hypothesized that most images would be of low quality and perceived usefulness, and that interrater agreement would be poor. Results: A total of 259 of 2915 patient-submitted images (8.9%) did not depict a skin condition at all. The final analysis comprised 3600 unique image evaluations. Dermatologist evaluators indicated that 1985 images (55.1%) were useful for medical decision-making and 2239 (62.2%) were of sufficient quality. Interrater agreement for a given image's diagnostic categorization was fair to substantial (κ range, 0.36-0.64), while agreement on image quality (κ range, 0.35-0.47) and perceived usefulness (κ range, 0.29-0.38) were fair to moderate. Senior faculty had higher odds of feeling comfortable with medical decision-making than junior faculty (odds ratio [OR], 3.68; 95% CI, 2.9-4.66; P < .001) and residents (OR, 5.55; 95% CI, 4.38-7.04; P < .001). Images depicting wounds (OR, 1.75; 95% CI, 1.18-2.58; P = .01) compared with inflammatory skin conditions and that were in focus (OR, 5.56; 95% CI, 4.63-6.67; P < .001) had higher odds of being considered useful for decision-making. Conclusions and Relevance: In this survey study including 10 dermatologists, a slight majority of patient-submitted images were judged to be of adequate quality and perceived usefulness. Fair agreement between dermatologists was found regarding image quality and perceived usefulness, suggesting that store-and-forward teledermatology initiatives should consider a physician's individual experiences and comfort level. The study results suggest that images are most likely to be useful when they are in focus and reviewed by experienced attending physicians for wound surveillance, but dermatologists may be burdened by irrelevant or unsuitable images.

RESUMO

AIMS: Fulvestrant is a selective oestrogen receptor (ER) degrader used in postmenopausal women with hormone receptor-positive advanced breast cancer. The study aim was to analyse demographics and outcomes of UK patients treated with fulvestrant monotherapy at nine representative centres. MATERIALS AND METHODS: Medical records of 459 patients with locally advanced or metastatic ER-positive, HER2-negative breast cancer treated with fulvestrant between August 2011 and November 2018 at nine UK centres were reviewed. Data were collated on demographics, progression-free survival, overall survival and disease response at first radiological assessment following fulvestrant initiation. Patients still alive by December 2018 were censored. RESULTS: Data from 429 of the 459 patients identified were eligible for inclusion in the analysis. The median age was 69 (range 21-95) and 64% (n = 275) had Eastern Cooperative Oncology Group performance status 0-1. Bone was the most commonly involved metastatic site (72%, n = 306). However, 295 (69%) patients had visceral involvement. Patients had received a median 2 (range 0-5) prior lines of endocrine therapy and median 0 (range 0-6) prior chemotherapies. Fulvestrant was first-line therapy in 43 patients (10%). The median duration of treatment was 5 months (range 1-88). The median progression-free survival was 5.5 months. In 51% of 350 patients radiologically assessed, there was evidence of disease response to fulvestrant. Fifteen per cent of these had a complete/partial response. Fulvestrant was discontinued predominantly due to disease progression, with 3% discontinued solely due to adverse events. The median overall survival for the whole cohort was 22.5 months (range 0-88). CONCLUSIONS: This is one of the largest studied cohorts of breast cancer patients treated with fulvestrant. This heavily endocrine-pretreated population reflects real-life use in the UK. Within this context, our retrospective data show that patients can experience maintained disease response when treated with fulvestrant, supporting the importance of equitable availability for all UK patients.
