A Month of Vestibular Migraine: Symptom Characterization Using Ecological Momentary Assessment.

OBJECTIVE(S): This study investigated the frequency and intensity of vestibular migraine (VM) symptoms using Ecological Momentary Assessment (EMA). This approach was intended to provide insights into the day-to-day experiences of individuals with VM, contributing to a more comprehensive understanding of this condition. METHODS: Participants reported symptoms to an automated text system, rating their dizziness over the prior 24 h as none, mild, moderate, or severe. Definitive Dizzy Days (DDDs) were defined as days with moderate or severe dizziness. A student's independent group t-test was used to compare the number of DDDs between VM and probable VM subjects. RESULTS: Sixty-six subjects were included, with an average of 29 days of pre-intervention data (SD = 1.4). The average number of days with no dizziness was 3.5 (SD = 6.5), mild dizziness was 9.1 (SD = 6.7), moderate dizziness was 11 (SD = 6.1), and severe dizziness was 5.4 (SD = 6.3). Out of the 66 patients, 52 were classified as VM and 14 as pVM. The average number of DDDs was not significantly different between VM (17.0, SD = 8.3) and pVM (15.3, SD = 10.0) patients, with a two-tailed p-value of 0.44. CONCLUSION: With EMA, we found that the average subject with VM had some degree of dizziness almost every day, and more than 15 DDDs per month. LEVEL OF EVIDENCE: III Laryngoscope, 2024.

Pouch abandonment is extremely rare even in the reoperative setting: A high-volume referral center experience.

BACKGROUND: Ileal pouch anal anastomosis is the preferred method for restoration of intestinal continuity after proctocolectomy. Successful ileal pouch anal anastomosis requires adequate reach of the ileal mesentery to the pelvis. Reach issues are a common cause for intraoperative pouch abandonment; however, data regarding contemporary abandonment rates are rare and nonexistent in the revisional setting. METHODS: A retrospective review was conducted of consecutive ileal pouch anal anastomosis surgery at a single referral center. Both initial or "primary" pouches and revisional pouch surgery were included. RESULTS: In total, 447 attempts at pouch anal anastomosis were made, with an 1.6% overall rate of intraoperative abandonment. Pouch abandonment was attributed to inadequate mesenteric reach during 3 surgeries, desmoid tumors in 2 surgeries, and insufficient remaining small bowel in 2 surgeries. Twelve patients required lengthening maneuvers including 6 S pouches (1%) and 6 H pouches (1%). One half (49%) of operations were revisional ileal pouch anal anastomosis surgery. Overall, reach issues led to intraoperative abandonment in only 0.4% of attempted primary pouches and 1.0% of revisional surgeries. A preoperative diagnosis of familial adenomatous polyposis was associated with pouch abandonment (P < .001). CONCLUSION: Extremely low pouch abandonment rates as a result of mesenteric reach can be achieved even in the revisional setting at a high-volume center with institutional expertise. In the revisional setting, intra-abdominal desmoids or the potential for short gut affects pouch abandonment rates as much as reach issues.

Incidence of Venous Thromboembolism after Primary Total Hip Arthroplasty with Mechanical Prophylaxis in Hong Kong Chinese.

Purpose: The incidence of deep vein thrombosis (DVT) following total hip arthroplasty (THA) without chemoprophylaxis could be as high as 50% in Caucasians. However, according to several subsequent studies, the incidence of venous thromboembolic events (VTE) in Asians was much lower. The routine use of chemoprophylaxis, which could potentially cause increased bleeding, infection, and wound complications, has been questioned in low-incidence populations. The objective of this study is to determine the incidence of VTE after primary THA without chemoprophylaxis in an Asian population using a fast-track rehabilitation protocol and to verify the safety profile for use of 'mechanical prophylaxis alone' in patients with standard risk of VTE. Materials and Methods: This is a retrospective cohort study of 542 Hong Kong Chinese patients who underwent primary THA without chemoprophylaxis. All patients received intermittent pneumatic compression and graduated compression stockings as mechanical prophylaxis. Multimodal pain management was applied in order to facilitate early mobilisation. Routine duplex ultrasonography was performed between the fourth and seventh postoperative day for detection of proximal DVT. Results: All patients were Chinese (mean age, 63.0±11.9 years). Six patients developed proximal DVT (incidence rate, 1.1%). None of the patients had symptomatic or fatal pulmonary embolism. Conclusion: The incidence of VTE after primary THA without chemical prophylaxis can be low in Asian populations when following a fast-track rehabilitation protocol. Mechanical prophylaxis alone can be regarded as a reasonably safe practice in terms of a balanced benefit-to-risk ratio for Asian patients with standard risk of VTE.

Personalizing Locoregional Therapy in Patients With Breast Cancer in 2024: Tailoring Axillary Surgery, Escalating Lymphatic Surgery, and Implementing Evidence-Based Hypofractionated Radiotherapy.

The management of axillary lymph nodes in breast cancer is continually evolving. Recent data now support omitting axillary lymph node dissection (ALND) in most patients with metastases in up to two sentinel lymph nodes (SLNs) during upfront surgery and those with residual isolated tumor cells after neoadjuvant chemotherapy (NACT). In the upfront surgery setting, ALND is still indicated, however, in patients with clinically node-positive breast cancer or more than two positive SLNs and, after NACT, in case of residual micrometastases and macrometastases. Omission of the sentinel lymph node biopsy (SLNB) can be considered in many postmenopausal patients with small luminal breast cancer, particularly when axillary ultrasound is negative. Several randomized controlled trials (RCTs) are currently aiming at eliminating the remaining indications for ALND and also establishing omission of SLNB in a broader patient population. The movement to deescalate axillary staging is in part because of the association between ALND and lymphedema, which is swelling of an extremity because of lymphatic damage and obstructed lymphatic drainage. To reduce the risk of developing this condition, patients undergoing ALND can undergo reverse mapping of the axilla and immediate reconstruction or bypass of the lymphatics from the involved extremity. Decongestion and compression are the foundation of conservative treatment for established lymphedema, while lymphovenous bypass and lymph node transfer are surgical procedures to address the physiologic dysfunction. Radiotherapy is an essential component of breast locoregional therapy: more than three decades of radiation research has optimized treatment according to patient's risk of local recurrence while substantially reducing the number of treatment visits. High-quality RCTs have shown the efficacy and safety of hypofractionation-more than 2Gy radiation dose per treatment (fraction)-significantly reducing the burden of radiotherapy treatment for many patients with breast cancer. In 2024, guidelines recommend no more than 15-16 fractions for whole-breast and nodal radiotherapy, with some recommending five fractions for whole-breast radiotherapy. In addition, simultaneous integrated boost (SIB) has been shown to be noninferior to sequential boost with regards to ipsilateral breast tumor recurrence with similar or reduced long-term side effects, also reducing overall treatment length. Further RCTs are underway investigating other indications for five fractions, including SIB and regional node irradiation, such that, in future, it may be possible for the majority of breast radiotherapy patients to be treated with a 1-week course. This manuscript serves to outline the latest updates on axillary surgical staging, lymphatic surgery, and evidence-based radiotherapy in the treatment of breast cancer.

Safety and Efficacy of Inpatient Infliximab Rescue Therapy for Acute Crohn's Disease Flares.

PURPOSE: Describe the safety, complications, and need for urgent surgery in patients requiring inpatient rescue infliximab for acute Crohn's disease (CD) flare. BACKGROUND: Infliximab is increasingly used for patients hospitalized with acute severe ulcerative colitis as rescue therapy; however, optimal management for patients hospitalized for CD flares remains unclear. METHODS: A single-institution retrospective study of patients aged 18+ admitted from 2008 to 2020 with acute Crohn's flare requiring induction of rescue infliximab therapy. Outcomes included postoperative and medication-related complications and need for urgent surgery. RESULTS: 52 patients were included in analysis; 8% required surgery on index admission, and 19% required surgery within 90 days of infliximab. Postoperative complications included 1 anastomotic leak, 3 superficial wound infections, 3 prolonged ileus, and 1 urinary infection. There were no adverse reactions to infliximab infusion, and medical complication rates were low. Patients with penetrating disease were more likely to undergo surgery within 90 days of infliximab (43% vs 8%; P = .01). Mean LOS was longer for patients undergoing surgery within 90 days of therapy compared to those who did not (13.4 vs 8.3 days, P = .04). CONCLUSION: Inpatient rescue infliximab is safe for treating acute Crohn's disease flare in addition to standard steroid therapy. The majority of patients hospitalized with Crohn's flare requiring rescue infliximab avoided surgery with low postoperative and medication-related complications. More research is needed to clarify the optimal rescue infliximab therapy dosage.

Continuous Subcutaneous Delivery of rhPTH(1-84) and rhPTH(1-34) by Pump in Adults With Hypoparathyroidism.

Context: Continuous subcutaneous infusion of recombinant parathyroid hormone (rhPTH) through a pump has been proposed as a therapeutic alternative for patients with chronic hypoparathyroidism who remain symptomatic or hypercalciuric on conventional treatment (calcium and active vitamin D) or daily injections of rhPTH(1-84) or rhPTH(1-34). However, the real-world evidence of the outcome of this novel therapy is limited. Case Descriptions: We report the clinical and biochemical outcomes of 12 adults with hypoparathyroidism (11 women, age 30-70 years, and 1 man, age 30 years) from 3 different clinical sites in the United States who were transitioned from conventional therapy to daily injections of rhPTH(1-84) or rhPTH(1-34) and then switched to continuous administration of rhPTH(1-84)/rhPTH(1-34) via pump therapy. In most patients, mean serum calcium concentrations increased while on PTH pump therapy compared with both conventional therapy (in 11 patients) and single/multiple daily rhPTH injections (in 8 patients). Despite this, 10 patients had lower median 24-hour urinary calcium levels while on PTH pump therapy compared with prior therapy (mean ± SD difference: -130 ± 222 mg/24 hours). All patients reported a qualitative decrease in hypocalcemic symptoms while receiving pump therapy. Three patients had pod failure at least once, and 1 patient developed an infusion site reaction. Conclusion: In this case series of 12 patients with chronic hypoparathyroidism treated with rhPTH(1-84)/rhPTH(1-34) administered via a pump, improvement in clinical and biochemical parameters were observed in the majority of the patients. Our observations indicate benefits of pump administration of rhPTH that warrant further investigation.

Transorbital and endonasal resection of a rare orbital ectopic atypical meningioma.

A female patient in her early 20s presented with increasing proptosis of her left eye over 2 months. She had no other signs of diplopia, pain or visual loss on initial presentation. Subsequent imaging of her orbits revealed a medial rectus tumour. A transorbital open biopsy of this tumour was non-diagnostic/inconclusive, hence a combined transorbital and endonasal resection of this tumour was performed. Histopathology of the resected tumour revealed an unusual inflammatory-rich spindle cell neoplasm, which was determined to be a primary orbital ectopic atypical meningioma. These tumours are exceedingly rare, with only case reports/series reported in the literature. Complete surgical resection with margins is the proposed treatment. The role of radiotherapy is still controversial. More studies are required to improve our knowledge of this condition.

Effects of the interplay between topology and function of an integrated urban development on patterns of user movement.

With the advent of distributed multi-sensory networks of devices, vast troves of real-time data can be gathered about our interactions with the built environment. These rich data sets can be mined to achieve improved and informed data-driven designs of buildings, neighborhoods, and potentially entire cities. Among those, integrated developments have the peculiarity of combining multiple functions within a compact space and, as such, behave as microcosms of a city that can help address the problem of urban sprawl and density. However, a general lack of data and framework about integrated developments hinders our ability to test design hypotheses about the complex interplay between heterogeneity in both space and function. Here, we apply a data-driven approach to analyze the joint influence of topology and function on user movement within a state-of-the-art integrated development in Singapore. Specifically, we leverage the network representation of the building and use movement data collected from 51 individuals over a month. We show evidence of correlation (40%) between the spatial network features and human movement at the building level. We are also able to quantify the relationship between the functional and spatial components of the integrated development through user movement. Previous studies have shown a 60% or higher correlation between the topology and human movement at the city or country scales. Our moderate correlation, therefore, implies that more factors influencing user movement are at play. The heterogeneity in the spatial function introduced trips with diverse origins and destinations. A further data-driven analysis integrating origins and destinations reveals both qualitative and quantitative means of studying the relationship between the built environment and the processes that take place in them.

Quantifying the adaptive landscape of commensal gut bacteria using high-resolution lineage tracking.

Gut microbiota can adapt to their host environment by rapidly acquiring new mutations. However, the dynamics of this process are difficult to characterize in dominant gut species in their complex in vivo environment. Here we show that the fine-scale dynamics of genome-wide transposon libraries can enable quantitative inferences of these in vivo evolutionary forces. By analyzing >400,000 lineages across four human Bacteroides strains in gnotobiotic mice, we observed positive selection on thousands of cryptic variants - most of which were unrelated to their original gene knockouts. The spectrum of fitness benefits varied between species, and displayed diverse tradeoffs over time and in different dietary conditions, enabling inferences of their underlying function. These results suggest that within-host adaptations arise from an intense competition between numerous contending variants, which can strongly influence their emergent evolutionary tradeoffs.

Microbial co-occurrences on catheters from long-term catheterized patients.

Catheter-associated urinary tract infections (CAUTIs), a common cause of healthcare-associated infections, are caused by a diverse array of pathogens that are increasingly becoming antibiotic resistant. We analyze the microbial occurrences in catheter and urine samples from 55 human long-term catheterized patients collected over one year. Although most of these patients were prescribed antibiotics over several collection periods, their catheter samples remain colonized by one or more bacterial species. Examination of a total of 366 catheter and urine samples identify 13 positive and 13 negative genus co-occurrences over 12 collection periods, representing associations that occur more or less frequently than expected by chance. We find that for many patients, the microbial species composition between collection periods is similar. In a subset of patients, we find that the most frequently sampled bacteria, Escherichia coli and Enterococcus faecalis, co-localize on catheter samples. Further, co-culture of paired isolates recovered from the same patients reveals that E. coli significantly augments E. faecalis growth in an artificial urine medium, where E. faecalis monoculture grows poorly. These findings suggest novel strategies to collapse polymicrobial CAUTI in long-term catheterized patients by targeting mechanisms that promote positive co-associations.

Primary pulmonary enteric adenocarcinoma presenting as a solitary skull mass.

Pulmonary enteric adenocarcinoma (PEAC) is a rare, aggressive variant of lung adenocarcinoma with early metastatic potential. We present the case of a male smoker in his 50s who presented with right-sided numbness, pain and headache. Imaging revealed a destructive skull base mass invading the right sphenoid sinus. Histopathology was consistent with PEAC. The diagnosis was metastatic PEAC with a distant spread to the skull and represents the first case reported in the literature. We present an associated literature review of the clinical presentation, histological features and management of PEAC with skull metastasis. Metastasis should be considered when evaluating any persistent cranial lesion. Diagnosis requires thorough clinical, radiological and pathological assessment. Treatment involves surgical resection, chemoradiation and targeted therapy. Prognosis directly correlates with clinical stage at presentation. This case highlights the importance of careful evaluation of skull lesions, even in patients without known primary malignancy. Early diagnosis and multimodal therapy may improve outcomes.

Therapeutic challenges in small cell carcinoma of the larynx.

Primary small cell neuroendocrine carcinoma (SCNC) of the larynx is a rare subtype of laryngeal cancer, accounting for less than 1% of all laryngeal tumours. It most commonly affects smokers in their fifth to sixth decade of life and is characterised by a high incidence of advanced disease at presentation and an aggressive clinical course. Here we present a case of SCNC of the larynx, presenting initially with dysphonia, and an associated literature review collating current knowledge regarding therapeutic approaches. After review of 260 cases in the literature we determined a disease-specific survival of 33.1%. Combined chemoradiotherapy is currently the recommended first-line treatment option.

Improving end-of-life care for people with dementia: a mixed-methods study.

BACKGROUND: Improving palliative and end-of-life care for people with dementia is a growing priority globally. This study aimed to integrate multiple perspectives on end-of-life care for people with dementia and carers, to identify clinically relevant areas for improvement. METHODS: The mixed-methods study involved surveys, interviews, and workshops with two participant groups: healthcare professionals and carers (individuals who provided care and support to a family member or friend). Healthcare professionals were invited to complete an online adapted version of the Australian Commission on Safety and Quality in Health Care, End-of-Life Care Toolkit: Clinician Survey Questions. Carers completed a hard copy or online adapted version of the Views of Informal Carers-Evaluation of Services (Short form) (VOICES-SF) questionnaire. Interview schedules were semi-structured, and workshops followed a co-design format. Findings were integrated narratively using a weaving approach. RESULTS: Five areas in which we can improve care for people with dementia at the end of life, were identified: 1) Timely recognition of end of life; 2) Conversations about palliative care and end of life; 3) Information and support for people with dementia and carers; 4) Person-and-carer-centred care; 5) Accessing quality, coordinated care. CONCLUSIONS: There are multiple areas where we can improve the quality of end-of-life care people with dementia receive. The findings demonstrate that the heterogeneous and challenging experiences of living with and caring for people with dementia necessitate a multidisciplinary, multifaceted approach to end-of-life care. The identified solutions, including care coordination, can guide local development of co-designed models of end-of-life care for people with dementia.

What care do people with dementia receive at the end of life? Lessons from a retrospective clinical audit of deaths in hospital and other settings.

BACKGROUND: The need for better end-of-life care for people with dementia has been acknowledged. Existing literature suggests that people dying with dementia have less access to palliative care, yet little is known about the care provided to people with dementia at the end of life. This study aimed to establish evidence related to end-of-life care for people dying with dementia in hospital compared to other settings. METHODS: A retrospective clinical audit of people who had a diagnosis of dementia and had accessed services within a local health district, who died between 2015 and 2019, was conducted. A total of 705 people were identified, and a subset of 299 people randomly selected for manual audit. Chi-square p-values were used to compare the place of death, and a t-test or non-parametric test was used to assess the significance of the difference, as appropriate. Measures of functional decline within one month of death were assessed using mixed effects logistic regression models. RESULTS: The characteristics of people differed by place of death, with people who died in hospital more likely to be living at home and to not have a spouse. Less than 1 in 5 people had advance care directives or plans. Many were still being actively treated at the time of death: almost half of people who died in hospital had an investigation in their final 72 hours, less than half of people were coded as receiving palliative care at death, and more than 2 in 3 people did not get access to specialist palliative care. Declining function was associated with the terminal phase. CONCLUSION: This study provides novel insights for those providing end-of-life care for people with dementia. Healthcare professionals and policy makers should consider how demographic characteristics relate to the places people with dementia receive end-of-life care. The care provided to people with dementia in the last year of their life highlights the need for more support to prepare advance care documentation and timely consideration for palliative care. Changes in markers of nutritional status and function in people with advanced dementia may help with identification of terminal phases.

Testicular Radiomics To Predict Pathology At Time of Postchemotherapy Retroperitoneal Lymph Node Dissection for Nonseminomatous Germ Cell Tumor.

INTRODUCTION: Testicular germ cell tumors are the most common malignancy in young adult males. Patients with metastatic disease receive standard of care chemotherapy followed by retroperitoneal lymph node dissection for residual masses >1cm. However, there is a need for better preoperative tools to discern which patients will have persistent disease after chemotherapy given low rates of metastatic germ cell tumor after chemotherapy. The purpose of this study was to use radiomics to predict which patients would have viable germ cell tumor or teratoma after chemotherapy at time of retroperitoneal lymph node dissection. PATIENTS AND METHODS: Patients with nonseminomatous germ cell tumor undergoing postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) between 2008 and 2019 were queried from our institutional database. Patients were included if prechemotherapy computed tomography (CT) scan and postchemotherapy imaging were available. Semiqualitative and quantitative features of residual masses and nodal regions of interest and radiomic feature extractions were performed by 2 board certified radiologists. Radiomic feature analysis was used to extract first order, shape, and second order statistics from each region of interest. Post-RPLND pathology was compared to the radiomic analysis using multiple t-tests. RESULTS: 45 patients underwent PC-RPLND at our institution, with the majority (28 patients) having stage III disease. 24 (53%) patients had teratoma on RPLND pathology, while 2 (4%) had viable germ cell tumor. After chemotherapy, 78%, 53%, and 33% of patients had cystic regions, fat stranding, and local infiltration present on imaging. After radiomic analysis, first order statistics mean, median, 90th percentile, and root mean squares were significant. Strong correlations were observed between these 4 features;a lower signal was associated with positive pathology at RPND. CONCLUSIONS: Testicular radiomics is an emerging tool that may help predict persistent disease after chemotherapy.

Strength-based cognitive-behavioural therapy and peer-to-peer support in the recovery process for people with schizophrenia: A randomised control trial.

BACKGROUND AND AIMS: Dysfunctional cognition and negative symptoms in schizophrenia are associated with persistently low social functioning and quality of life (QoL). Recovery interventions report only a modest effect in improving social functioning and QoL. This study examined the therapeutic effects and pathways of interventions using strength-based cognitive-behavioural therapy (SBCBT) and peer-to-peer support (PSP) approaches. METHODS: A randomised control trial compared SBCBT, PSP and TAU (treatment-as-usual) by recruiting 127 individuals with schizophrenia spectrum disorders and low social functioning. RESULTS: The three-group comparison found SBCBT produced improved social functioning and social support at post-intervention and 6-month follow-up while PSP reported improved social QoL and defeatist beliefs, but none remained at 6-month follow-up. Unsurprising, no improvement was found in any areas for TAU, both at post-test and 6-month follow-up. Regarding mechanisms of change, improvements in hope and personal recovery consistently and significantly accounted for improvements in social functioning and many aspects of QoL of participants, thus indicating the important contribution of hope and personal recovery in strength-based interventions for people with schizophrenia. CONCLUSION: This rigorously designed study provides the first few solid empirical evidence on the effectiveness of SBCBT and PSP in recovery from schizophrenia and provides initial evidence of the linkage between dysfunctional cognition, hope and recovery in schizophrenia.
