RESUMO
OBJECTIVE: Thyroid hormone under-replacement and over-replacement are associated with adverse health outcomes. This systematic review aimed to evaluate the extent of thyroid hormone replacement adequacy for patients with known hypothyroidism in real-word settings, excluding those receiving thyroid hormone suppressive therapy as thyroid cancer treatment. DESIGN: Four electronic databases (Embase [Ovid], Medline [Ovid], PubMed and SCOPUS) were searched for published and unpublished observational studies until 12 December 2022. The results of the studies were meta-analysed to calculate pooled prevalence estimates for thyroid hormone supplementation adequacy, over-replacement and under-replacement. Quality assessment of studies was performed using the Joanna-Briggs appraisal tool for prevalence studies. RESULTS: Seven studies with a total of 4230 patients were eligible for quantitative synthesis. The pooled prevalence estimates of adequate thyroid replacement, over-replacement and under-replacement were 0.55 (95% confidence interval [CI]: 0.49-0.60, p = .001), 0.20 (95% CI: 0.14-0.27, p = .001) and 0.24 (95% CI: 0.13-0.36, p = .001), respectively. Four studies subclassified hypothyroidism and hyperthyroidism into overt and subclinical. The pooled prevalence of overt and subclinical hyperthyroidism was 0.04 (95% CI: 0.00-0.11, p = .01) and 0.17 (95% CI: 0.09-0.27 p = .001), respectively. For overt and subclinical hypothyroidism, the pooled prevalence was 0.02 (95% CI: 0.01-0.03, p = .001) and 0.20 (95% CI: 0.12-0.29, p = .001), respectively. CONCLUSIONS: On average, approximately half of patients with hypothyroidism are only treated to target euthyroidism. In real-world practice, a significant number of patients are over-treated or under-treated, leading to adverse healthcare outcomes. It is imperative that more effective thyroid monitoring strategies be implemented, with an emphasis on primary care thyroid function monitoring, to minimise inappropriate thyroid replacement treatments and optimise healthcare outcomes at a population level.

INTRODUCTION: Gliomatosis cerebri (GC) is a rare fatal widespread infiltrating CNS tumor. As consistent disease features have not been established, the tumor comprises a diagnostic challenge. METHODS: We conducted a systematic literature search for published case reports and case series on patients with histologically confirmed GC. Clinical, diagnostic, neuroimaging, histopathological, and molecular data on individual or summary patient level were extracted and analyzed. RESULTS: A total of 274 studies were identified, including 866 patients with individual-level data and 782 patients with summary data (58.9% males, mean age 43.6 years). Seizures (49.8%) were the most common presenting symptom followed by headache (35.9%), cognitive decline (32.2%), and focal motor deficits (32%). Imaging studies showed bilateral hemisphere involvement in 65%, infratentorial infiltration in 29.9% and a focal contrast-enhanced mass (type II GC) in 31.1% of cases. MRI (extensive hyperintensities in T2/FLAIR sequences) and MR spectroscopy (elevated choline, creatinine, and myoinositol levels; decreased NAA levels) showed highly consistent findings across GC patients. Low-grade and anaplastic astrocytoma were the most prevalent diagnostic categories, albeit features of any histology (astrocytic, oligodendroglial, oligoastrocytic) and grade (II-IV) were also reported. Among molecular aberrations, IDH1 mutation and MGMT promoter methylation were the most commonly reported. Increasing time elapsed from symptom onset to diagnosis comprised the only independent determinant of the extent of CNS infiltration. CONCLUSION: A distinct clinical, neuroimaging, histopathological, or molecular GC phenotype is not supported by current evidence. MRI and MR spectroscopy are important tools for the diagnosis of the tumor before confirmation with biopsy.

Gliomatosis cerebri (GC) comprises a rare widespread infiltrating growth pattern of diffuse gliomas. We explored the incidence patterns and survival rates of GC in a population-based registration sample from the Surveillance, Epidemiology and End, Results database (1973-2012). GC cases (n = 176) were identified based on their International Classification of Diseases in Oncology (ICD-O-3) morphology code (9381). We calculated age-adjusted incidence rates (AIR) and evaluated temporal trends. Survival was assessed with Kaplan-Meier curves and Cox regression models. The annual AIR of GC was 0.1/million. We noted increasing trends in the preceding registration years (1973-2002; annually, + 7%) and a tendency of clinical/radiological approaches to substitute the gold-standard histological assessment for diagnosis. GC was diagnosed in the entire age spectrum (range 1-98 years), but higher incidence rates (0.43/million) were noted among the elderly (≥ 65 years). A slight male preponderance was identified (male-to-female ratio: 1.4). Median overall survival was 9 months with a 5 year survival rate of 18%. Increasing age, primary tumor location not restricted to the cerebral hemispheres and rural residence at diagnosis were identified as negative prognostic factors, whereas receipt of radiotherapy, surgical treatment, race and method of diagnosis were not associated with outcome. This first comprehensive overview of GC epidemiology exemplifies the rarity of the disease, provides evidence for male preponderance and increased incidence among the elderly and shows lower survival rates compared to the published single center reports. Expansion of registration to histological and molecular characteristics would allow emergence of clinical prognostic factors at the population level.

OBJECTIVE: The National Health Service (NHS) recognised the risk to public health brought by climate change by launching the Greener NHS National Programme in 2020. These organisational changes aim to attain net zero direct carbon emissions. This article reviews the literature on initiatives aimed at mitigating the environmental impact of ENT practice. METHOD: Systematic review of the literature using scientific, healthcare and general interest (public domain) databases. RESULTS: The initiatives reviewed can be broken down into strategies for mitigating the carbon footprint of long patient stay, use of operative theatres and healthcare travel. The carbon footprint of in-patient stay can be mitigated by a shift towards day-case surgery. The ENT community is currently focused on the reduction of theatre waste and the use of disposable instruments. Furthermore, supply chains and healthcare delivery models are being redesigned to reduce travel. CONCLUSION: Future areas of development include designing waterless theatre scrubs, waste-trapping technologies for anaesthetic gases and a continuing investment in virtual healthcare.

OBJECTIVE: We undertook a systematic review of the literature with meta-analysis to identify the role of obesity (BMI ≥30) in the patient characteristics presenting with spontaneous cerebrospinal fluid (sCSF) leaks of the lateral skull base and the outcomes of their repair. DATA SOURCES: A Systematic Review of English Articles using MEDLINE, EMBASE, and Cochrane Library. REVIEW METHODS: The research algorithm included the following keywords: "spontaneous CSF leak," "lateral skull base," "temporal bone," "meningocele," "encephalocele," and "otorrhea." We also manually searched the references of included studies, to identify possible studies missed during our literature search. RESULTS: More than two-thirds of the patients were female (69.2%) and often were obese (mean BMI 36.5 kg/m2) with a mean age of 57. Most common presenting symptoms were otorrhea and hearing loss. Most authors did not report a routine use of a post-operative lumbar drain. Most patients had a single skull base defect and encephaloceles prolapsing through, across obese and non-obese groups. Median length of stay in hospital was 3.2 days, and the majority of patients did not have any recurrence during their follow-up (89.6%), which was not affected by obesity. CONCLUSION: Obesity does not affect length of hospital stay or recurrence rate following surgical repair of lateral skull base sCSF leaks. Surgical repair is a safe and viable approach in the management of obese patients with sCSF leaks in the temporal bone. LEVEL OF EVIDENCE: NA Laryngoscope, 134:2012-2018, 2024.

The applications of artificial intelligence (AI) in temporal bone (TB) imaging have gained significant attention in recent years, revolutionizing the field of otolaryngology and radiology. Accurate interpretation of imaging features of TB conditions plays a crucial role in diagnosing and treating a range of ear-related pathologies, including middle and inner ear diseases, otosclerosis, and vestibular schwannomas. According to multiple clinical studies published in the literature, AI-powered algorithms have demonstrated exceptional proficiency in interpreting imaging findings, not only saving time for physicians but also enhancing diagnostic accuracy by reducing human error. Although several challenges remain in routinely relying on AI applications, the collaboration between AI and healthcare professionals holds the key to better patient outcomes and significantly improved patient care. This overview delivers a comprehensive update on the advances of AI in the field of TB imaging, summarizes recent evidence provided by clinical studies, and discusses future insights and challenges in the widespread integration of AI in clinical practice.
RESUMO
Objectives: A novel 'subscription-type' funding model was launched in England in July 2022 for ceftazidime/avibactam and cefiderocol. We explored the views of infection consultants on important aspects of the delinked antimicrobial funding model. Methods: An online survey was sent to all infection consultants in NHS acute hospitals in England. Results: The response rate was 31.2% (235/753). Most consultants agreed the model is a welcome development (69.8%, 164/235), will improve treatment of drug-resistant infections (68.5%, 161/235) and will stimulate research and development of new antimicrobials (57.9%, 136/235). Consultants disagreed that the model would lead to reduced carbapenem use and reported increased use of cefiderocol post-implementation. The presence of an antimicrobial pharmacy team, requirement for preauthorization by infection specialists, antimicrobial stewardship ward rounds and education of infection specialists were considered the most effective antimicrobial stewardship interventions. Under the new model, 42.1% (99/235) of consultants would use these antimicrobials empirically, if risk factors for antimicrobial resistance were present (previous infection, colonization, treatment failure with carbapenems, ward outbreak, recent admission to a high-prevalence setting).Significantly higher insurance and diversity values were given to model antimicrobials compared with established treatments for carbapenem-resistant infections, while meropenem recorded the highest enablement value. Use of both 'subscription-type' model drugs for a wide range of infection sites was reported. Respondents prioritized ceftazidime/avibactam for infections by bacteria producing OXA-48 and KPC and cefiderocol for those producing MBLs and infections with Stenotrophomonas maltophilia, Acinetobacter spp. and Burkholderia cepacia. Conclusions: The 'subscription-type' model was viewed favourably by infection consultants in England.
RESUMO
Single-anastomosis duodenoileal bypass with sleeve gastrectomy/one anastomosis duodenal switch (SADI-S/OADS) was developed as a bariatric operation with reduced overall morbidity and lasting weight loss results. We performed a systematic review of the literature, including 14 studies reporting on weight loss, comorbidity resolution, postoperative complications, and nutritional deficiencies following SADI-S. Twelve months after SADI-S, the mean total body weight lost ranged from 21.5 to 41.2%, with no weight regain being observed after 24 months. The comorbidity resolution rate was 72.6% for diabetes, 77.2% for dyslipidemia, and 59.0% for hypertension cases. The need for reoperation was the most common postoperative complication. While several patients developed nutrient deficiencies, SADI-S seems to be an overall safe and effective bariatric operation.

PURPOSE: There is a paucity of studies concerning health literacy (HL) of parents/guardians of patients in paediatric surgery. The purpose of our study is to measure HL levels of parents/guardians of paediatric surgery patients and to explore the determinants of low HL levels in this population. MATERIALS AND METHODS: We conducted a cross-sectional study from December 2016 to July 2018 through in-person interviews of parents/guardians of paediatric surgical patients. Sociodemographic and clinical data were recorded, and HL levels were calculated using a validated tool (HLS-EU-Q16). In order to examine the impact of various sociodemographic variables and clinical data on HL, a multivariate regression model was run. RESULTS: A total of 1000 participants were recruited (recruitment rate 93.5%). Slightly less than half (44.2%) presented problematic or inadequate HL levels. The results of the regression analysis showed that nationality other than Greek (ß = -2.180, P < 0.001) and lower health insurance status (ß = -0.461, P < 0.05) were associated with lower HL levels. HL was found positively associated with the educational level of the parent (ß = -0.775, P < 0.001) and being a health professional (ß = 1.791, P < 0.001). CONCLUSION: The prevalence of low HL levels in the parents/guardians of paediatric surgical patients is high and should not be neglected both in the pre-operative and post-operative setting. Communication should be tailored to the specific needs of each individual to achieve better engagement and quality of care.

BACKGROUND: There is currently no consensus regarding the optimal type of peritoneal dialysis catheter (PDC). We compared the outcomes of PDCs according to the number of cuffs, intercuff and intraperitoneal segment shape, and presence of a weighted tip. METHODS: A systematic review of the literature was performed using the MEDLINE and Cochrane Library databases (end-of-search date: October 16th, 2019). We included studies comparing double-cuff vs. single-cuff, swan-neck vs. straight-neck, coiled-tip vs. straight-tip, and weighted vs. non-weighted PDCs for the outcomes of interest. We performed meta-analyses using the random-effects model. We assessed the risk of bias using the Newcastle-Ottawa scale and the Cochrane Collaboration's Tool. RESULTS: In total, 38 studies were identified, of which 20 were randomized controlled trials (RCTs) and 18 were observational studies. No statistically significant differences were detected between double-cuff vs. single-cuff, swan-neck vs. straight-neck, and coiled-tip vs. straight tip PDCs in any of the outcomes of interest. Weighted catheters were associated with significantly lower rates of tunnel infection (relative risk [RR] 0.52, 95% confidence interval [CI] 0.31-0.95, p = 0.03), migration (RR 0.07, 95% CI 0.03-0.16, p < 0.001), drainage failure (RR 0.62, 95% CI 0.39-0.96, p = 0.03), cuff extrusion (RR 0.40, 95% CI 0.21-0.74, p < 0.001), and complication-related removal (RR 0.53, 95% CI 0.44-0.64, p < 0.001). DISCUSSION: Among the different types of PDCs, weighted catheters result in lower complication rates and superior long-term outcomes compared to non-weighted catheters. Other aspects of the catheter design do not significantly affect PDC outcomes. PROTOCOL REGISTRATION: PROSPERO 2020 CRD42020158177.

Meningoencephalocoeles are herniations of intracranial contents through skull base defects. Patients may present with a plethora of symptoms ranging from cerebrospinal fluid (CSF) rhinorrhoea to epileptic convulsions, or indeed may be asymptomatic. We present a case of a 24-year-old man suffering from new onset, drug-resistant tonic-clonic seizures. Imaging studies revealed neural tissue and meninges protruding through the pterygoid portion of the sphenoid bone, into the anteromedial aspect of the middle cranial fossa. An image-guided endoscopic transnasal transpterygoid approach was carried out as a joint otolaryngological and neurosurgical procedure, resulting in the patient being seizure-free for over 12 months postoperatively. There is a paucity of literature supporting such an endoscopic approach to treat epilepsy secondary to a meningoencephalocoele. We illustrate that this is a safe and minimally invasive treatment option which ultimately rendered the patient free of all anticonvulsants.

BACKGROUND: Gliomatosis cerebri (GC) is a fatal diffusely infiltrating glioma. Because of its rarity, only scarce evidence is available regarding outcome predictors and the proper management of GC. METHODS: Reported studies of patients with histologically confirmed GC were systematically reviewed and individual patient-level data (n = 523) extracted. Multivariable Cox proportional hazard models were fit for overall survival (OS) and progression-free survival (PFS). RESULTS: The median OS and PFS were 13 and 10 months, with 5-year rates of 18% and 13%, respectively. Age ≥65 years at diagnosis (hazard ratio for OS [HROS], 2.32; 95% confidence interval [CI], 1.62-3.31), high-grade tumor (HRPFS for grade III, 1.57; 95% CI, 1.02-2.40; HRPFS for grade IV, 1.74; 95% CI, [0.98-3.10), GC type II (HROS, 1.49; 95% CI, 1.12-1.98; HRPFS, 1.56; 95% CI, 1.04-2.34), more central nervous system (CNS) regions involved (HROS, 1.09; 95% CI, 1.01-1.18), focal neurological deficits (HROS, 1.41; 95% CI, 1.07-1.86), cerebellar symptoms (HRPFS, 2.20; 95% CI, 1.42-3.39), more symptoms at presentation (HROS, 1.21; 95% CI, 1.05-1.40), Karnofsky performance scale score <70 (HROS, 3.58; 95% CI, 1.73-7.39; HRPFS, 4.48; 95% CI, 1.39-14.4), magnetic resonance imaging contrast enhancement (HROS, 1.48; 95% CI, 1.12-1.96; HRPFS, 1.74; 95% CI, 1.18-2.55), symmetric bilateral CNS invasion (HROS, 1.42; 95% CI, 1.03-1.96), and high proliferation index (Ki-67 >5%; HROS, 2.32; 95% CI, 1.11-4.86) were independent predictors of poor outcomes. In contrast, seizure occurrence (HROS, 0.77; 95% CI, 0.60-1.00; HRPFS, 0.68; 95% CI, 0.47-0.95), isocitrate dehydrogenase 1 mutation (HROS, 0.16; 95% CI, 0.05-0.49), and O6-methylguanine-DNA-methyltransferase promoter methylation (HROS, 0.23; 95% CI, 0.09-0.59) were associated with prolonged survival. Chemotherapy and surgical resection were associated with improved outcomes, but radiotherapy, whether monotherapy or combined with chemotherapy, was not superior to chemotherapy alone. CONCLUSIONS: In the largest study to date on GC, we have identified clinical, imaging, and molecular outcome predictors that are similar to other gliomas and highlight the beneficial effect of chemotherapy and surgical resection, when feasible, on outcomes.
