Aim: To establish how oral and maxillofacial surgery units in the UK manage patients requiring dental extractions who are currently taking, or have previously taken, bisphosphonates and to review current guidelines for management of these patients.Methods: Postal questionnaire sent to 117 oral and maxillofacial surgery units in the UK.Results: 63 replies were received (54% response rate). Only 8% of the units who responded have a protocol for managing these patients. The current strategies for the prevention of bisphosphonate osteonecrosis include chlorhexidene mouthwash and pre- and post-operative antibiotics.Discussion: Bisphosphonate osteonecrosis (BON) is likely to become and increasing problem due to the large number of patients being prescribed drugs of this class. The aetiology and pathogenesis is BON is not clear but more similarities exist to 'phossy jaw' and osteopetrosis than to osteoradionecrosis. Where oral surgery is required, the use of mouthwash and antibiotics should be considered. The surgical technique should be atraumatic and where possible each sextant of the mouth should be treated in a staged manner. [ABSTRACT FROM AUTHOR]

BACKGROUND: While various conceptualizations of the link between childhood adversity and later depression have been offered, most have not accounted for the possibility that early adversity predicts continuing stress proximal to depression onset. Thus, the present study tested the possible mediating role of recent stress in the association between early adversity and depression in late adolescence.MethodStudy questions were examined in a longitudinal community sample of 705 youth who were contemporaneously assessed for early adversity exposure prior to age 5 years, chronic and episodic stress at age 15 years, and major depression prior to age 15 years and between 15 and 20 years. RESULTS: Total youth stress burden at age 15 years mediated the effect of early adversity on depression between ages 15 and 20 years, and none of the observed relationships were moderated by onset of depression prior to age 15 years. CONCLUSIONS: These findings suggest that continued stress exposure proximal to depression onset largely accounts for the association between early adversity and depression in late adolescence. Intervention should thus focus on disrupting the continuity of stressful conditions across childhood and adolescence. Future studies of the neurobiological and psychosocial mechanisms of the link between early experiences and depression should explore whether the effects of early experiences are independent of continuing adversity proximal to depressive onset.

Vascular disease, which can be asymptomatic until arterial stenosis is severe, is common in head and neck cancer patients as the risk factors for both cancer and atherosclerosis are similar. Although studies of common and internal carotid artery stenosis in head and neck patients have been reported, none have specifically assessed the external carotid system, especially in asymptomatic patients undergoing major microvascular free flap reconstructive surgery. A prospective study of 44 patients using pre-operative duplex scanning to assess the common, external and internal carotid arteries bilaterally. Eighteen patients (41%) had no obvious carotid disease in any vessel. Although the remaining 26 patients (59%) had some carotid tree stenosis, only nine patients (20% of study group) had disease affecting the external carotid artery, with significant stenosis (greater than 50%) of this vessel being found in only three patients (7%). A correlation was found between the degree of carotid stenosis and hypertension (P<0.05). No correlation was found between carotid artery stenosis and flap failure (t=5.4; P=1). Significant stenosis of the external carotid artery, even in the presence of atherosclerosis elsewhere in the carotid tree, is uncommon. The screening of the external carotid artery in head and neck patients requiring microvascular reconstruction should be considered when there are significant risk factors for carotid stenosis, including hypertension.

The development of infra-clavicular lymph node metastasis from head and neck squamous cell carcinoma is an uncommon event. We present a rare case of bilateral axillary nodal metastasis that developed in a patient previously treated for a primary ethmoidal squamous cell carcinoma. To our knowledge, there have only been five case reports in the English literature, accounting for a total of 10 patients, which documented a clinically apparent metastasis to axillary lymph nodes from various head and neck malignancies. Significantly however, the simultaneous ipsilateral and contralateral lymphatic spread of disease from a tumour in the para-nasal sinus, so as to involve bi-axillary nodes, has not been previously reported. We discuss the possible pathogenesis and the prognostic significance of this manifestation. [ABSTRACT FROM AUTHOR]

Abstract Background The EPILYMPH study applied a detailed occupational exposure assessment approach to a large multi-centre case–control study conducted in six European countries. This paper analysed multiple myeloma (MM) risk associated with level of education, and lifetime occupational history and occupational exposures, based on the EPILYMPH data set. Methods 277 MM cases and four matched controls per each case were included. Controls were randomly selected, matching for age (+/− 5 years), centre and gender. Lifetime occupations and lifetime exposure to specific workplace agents was obtained through a detailed questionnaire. Local industrial hygienists assessed likelihood and intensity for specific exposures. The odds ratio and 95% confidence intervals (OR, 95% CI) were calculated for level of education, individual occupations and specific exposures. Unconditional logistic regression models were run for individual occupations and exposures. Results A low level of education was associated with MM OR=1.68 (95% CI 1.02-2.76). An increased risk was observed for general farmers (OR=1.77; 95% CI 1.05-2.99) and cleaning workers (OR=1.69; 95% CI 1.04-2.72) adjusting for level of education. Risk was also elevated, although not significant, for printers (OR=2.06; 95% CI 0.97-4.34). Pesticide exposure over a period of ten years or more increased MM risk (OR=1.62; 95% CI 1.01-2.58). Conclusion These results confirm an association of MM with farm work, and indicate its association with printing and cleaning. While prolonged exposure to pesticides seems to be a risk factor for MM, an excess risk associated with exposure to organic solvents could not be confirmed.

Abstract Background Repeated rehearsal is one method by which verbal material may be transferred from short- to long-term memory. We hypothesised that extended engagement of memory structures through prolonged rehearsal would result in enhanced efficacy of recall and also of brain structures implicated in new learning. Twenty-four normal participants aged 55-70 (mean = 60.1) engaged in six weeks of rote learning, during which they learned 500 words per week every week (prose, poetry etc.). An extensive battery of memory tests was administered on three occasions, each six weeks apart. In addition, proton magnetic resonance spectroscopy (1H-MRS) was used to measure metabolite levels in seven voxels of interest (VOIs) (including hippocampus) before and after learning. Results Results indicate a facilitation of new learning that was evident six weeks after rote learning ceased. This facilitation occurred for verbal/episodic material only, and was mirrored by a metabolic change in left posterior hippocampus, specifically an increase in NAA/(Cr+Cho) ratio. Conclusion Results suggest that repeated activation of memory structures facilitates anamnesis and may promote neuronal plasticity in the ageing brain, and that compliance is a key factor in such facilitation as the effect was confined to those who engaged fully with the training.

Abstract Background Bladder cancer is the fourth most frequent malignancy among Uruguayan men. A previous study from Uruguay suggested a high risk of bladder cancer associated with maté drinking. We conducted an additional case-control study in order to further explore the role of non-alcoholic beverages in bladder carcinogenesis. Methods In the time period 1996–2000, 255 incident cases with transitional cell carcinoma of the bladder and 501 patients treated in the same hospitals and in the same time period were frequency matched on age, sex, and residence. Both cases and controls were face-to-face interviewed on occupation, tobacco smoking, alcohol drinking and intake of maté, coffee, tea, and soft drinks. Statistical analysis was carried out by unconditional multiple logistic regression. Results Ever maté drinking was positively associated with bladder cancer (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.2–3.9) and the risk increased for increasing duration and amount of maté drinking. Both coffee and tea were strongly associated with bladder cancer risk (OR for coffee drinking 1.6, 95% CI 1.2–2.3; OR for tea drinking 2.3, 95% CI 1.5–3.4). These results were confirmed in a separate analysis of never-smokers. Conclusion Our results suggest that drinking of maté, coffee and tea may be risk factors for bladder carcinoma in Uruguay.

Abstract Background Once considered as the main public health problem in developed countries, obesity has become a major problem throughout the world and developing countries, like Iran, are joining the global obesity pandemic. We determined the prevalence of overweight, obesity, and hypertension in a large cohort of Iranians and compared age-adjusted rates with the rates in the US. Methods Golestan Cohort Study is a population-based study of 8,998 men and women, aged 35-81 years, from urban and rural areas. Anthropometric parameters were measured by interviewers. Prevalence rates were directly adjusted to the 2000 United States standard population. Results The age-adjusted prevalence rates of overweight (BMI ≥ 25 kg/m2) and obesity (BMI ≥ 30 kg/m2) in this Iranian population were 62.2% and 28.0%, respectively. Both overweight and obesity were more common in women than men. Age-adjusted prevalence of overweight was significantly higher in Iranian women compared to the American women (68.6% vs. 61.6%), while the age-adjusted prevalence of obesity is closer in these two populations (34.9% vs. 33.2%). Iranian men—compared to American men—had significantly lower age-adjusted prevalence of overweight (53.7% vs. 68.8%) and obesity (16.2% vs. 27.5%). Age-adjusted prevalence of hypertension was higher in Iranian women than American women (35.7% vs. 30.5%). Diabetes mellitus was reported in 6.2% of participants. Mean waist-to-hip ratio (WHR) among women was 0.96. Smoking rates in men and women were 33.2% and 2.2%, respectively. Conclusion The prevalence of obesity, overweight, and hypertension in Iran is as high as the US. However, Iranian women are more obese than American women and Iranian men are less obese than their American counterparts. This discrepancy might be due to the low rate of smoking among Iranian women. Iranian women have higher mean WHR than what WHO has defined in 19 other populations.

Although local anesthetic injections are commonly used in dental practice, the complex neurovascular anatomy of the face can present the practitioner with unexpected complications. Several reports document adverse events related to inferior dental blocks (IDBs), whereas long buccal nerve blocks are usually performed without incident. We describe a previously unreported complication of a long buccal nerve block involving blanching, pain, and paresthesia specifically within the infraorbital arterial territory of the face. We had previously reported an identical event resulting from an IDB. We discuss the facial vascular relationships that might explain this complication and how to manage it. [ABSTRACT FROM AUTHOR]

Primary epithelial submandibular gland (SMG) tumours are uncommon, accounting for 8-12% of all salivary gland neoplasms, and most studies come from large specialised centres. There is little published about the relative frequency and outcome of SMG tumours treated in general hospitals. A retrospective study from two district general hospitals over a 10 year period (1996-2005). Seventeen benign (68%) and eight malignant (32%) tumours were included. A painless mass was the most common presentation. Pain and paraesthesia were not pathognomonic of malignancy. Pleomorphic adenoma accounted for all 17 benign tumours and adenoid cystic carcinoma was the commonest malignant tumour. Fine needle aspiration cytology (FNAC) accurately identified 78% of the benign tumours but none of the malignant tumours. Pre-operative imaging was also unable to distinguish malignant from benign tumours. Incomplete excision was reported in 20% of cases and was more common for malignant tumours. It may be difficult to distinguish benign from malignant SMG tumours on clinical examination and pre-operative investigations. Any suspected submandibular tumour should be considered for early treatment even when FNAC is suggestive of a benign tumour. [ABSTRACT FROM AUTHOR]

Dystroglycan (DG), a non-integrin adhesion molecule, is formed by two subunits, alpha- and beta-DG, which bind to extracellular matrix molecules and cytoskeleton. DG expression is frequently reduced in human cancers and has been related to tumor grade and aggressiveness. The exact proteolytic processing of beta-DG remains largely unknown. In this study, we investigated the correlation of beta-DG degradation with invasiveness in oral squamous cell carcinoma (OSCC) and its possible processing by matrix metalloproteinases (MMP). Immunohistochemical staining was used to assess beta-DG expression in 60 cases of OSCC. The effects of the MMP inhibitor 1,10-phenanthroline on tumour cell invasion and beta-DG degradation were investigated using in vitro invasion assays and immunoblot analysis. Co-immunoprecipitation and N-terminal sequencing were performed to determine the possible cleavage site of beta-DG by MMP. The alpha- and beta-DG expression was reduced or lost in OSCC. In four cell lines studied (SCC-4, SCC-9, SCC-15 and SCC-25), Western blot revealed a 30kDa fragment of beta-dystroglycan (beta-DG30) in addition to beta-DG itself. beta-DG degradation was almost abolished using 1,10-phenanthroline and there was a significant decrease in tumor cell invasion. The N-terminal sequence of beta-DG30 was detected as Ile-Asn-Thr-Asn, or Ile-Val-Thr-Gln. We conclude that beta-DG degradation may play a role both in OSCC invasion and metastasis. MMP activity seems to be one mechanism for beta-DG processing into beta-DG30. [ABSTRACT FROM AUTHOR]

Background: Prenatal exposure to persistent organic pollutants (POPs) has been linked to adverse pregnancy outcomes. Existing disparities in exposure across populations highlight the need for identifying modifiable risk factors. Here, we investigated the determinants of serum levels of polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs) in pregnant African American women (N = 54)., Methods: Concentrations of 2,2'4,4'-tetrabromodiphenyl ether (BDE-47), 2,2',4,4',5-pentabromodiphenyl ethe (BDE-99), 2,2',4,4',6-pentabromodiphenyl ether (BDE-100), hexachlorobenzene (HCB), and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) were measured in first trimester maternal serum from a subset of women enrolled in the Atlanta African American Maternal Child Cohort. Home characteristics, cleaning behaviors, diet, and demographic information were collected via survey questionnaires. Associations between individual determinants and individual PBDE and OCP concentrations were assessed using linear regression., Results: Pregnant women who frequently ate red meat, cheese, milk, or yogurt had elevated levels of HCB and p,p'-DDE compared to those who ate these products less frequently (e.g., red meat: β=0.21; 95% CI=-0.07, 0.48 for p,p'-DDE), while pregnant women who reported living in apartments, homes ≥10 years old, or had couches ≥5 years old, had increased levels of PBDEs compared to reference groups. Pregnant women who vacuumed and cleaned their home more frequently showed decreased levels of PBDEs relative to reference groups (e.g., vacuuming: BDE-100 β= -0.81, 95% CI= -1.55, -0.06)., Conclusions: Our results illustrate modifiable determinants of PBDE and OCP exposures in pregnant women and emphasize the potential to reduce the body burden of these POPs both directly, by changing diet, residence, or home furnishings, and indirectly through cleaning methods., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 Elsevier Inc.

Background: The radial forearm free flap (RFFF) is widely used in head and neck reconstruction and serves as a versatile option for complex soft tissue eyelid and orbital socket reconstruction, particularly following orbital exenteration. This study evaluated the success and complication rates of RFFF in these contexts., Methods: A literature search of the PubMed, Dynamed, DARE, EMBASE, Cochrane and British Medical Journal electronic databases was conducted (PROSPERO registration number CRD42024584536)., Results: Twenty-two studies met the inclusion criteria, reporting 40 RFFF procedures in 40 patients (ages: 21-93, M:F 2.1:1). Of these, 65% (n=26) of the RFFFs were used for orbital socket reconstruction, with 75.7% (n=28) performed after cancer resection. The pooled success rate of the RFFFs in orbital and eyelid reconstruction was 92.8% (95% CI, 83.25 to 100, P = 0.39, I² = 5%) and the pooled complication rate was 8.62% (95% CI, 0% to 24.98%, P<0.01, I² = 78%). Flap failure occurred in 10% (n=4) of cases, primarily due to wound dehiscence (n=2)., Conclusions: RFFFs demonstrate success and complication rates comparable to traditional flaps used in eyelid and orbital reconstruction, such as the anterolateral thigh, rectus abdominis and latissimus dorsi flaps. It offers functional and cosmetic benefits, particularly for reconstruction after orbital exenteration. The RFFF is a reliable option for complex orbital and eyelid reconstructions and should be considered when local options are unavailable. Standardised reporting and further research are needed to validate long-term outcomes and minimise donor site complications., (Copyright © 2025 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

The proposed study sought to investigate whether maternal experiences of racial discrimination and gendered racial stress are associated with offspring executive functioning. Total 266 Black mother-child pairs in the United States were assessed from pregnancy through child age of 4 years. We hypothesized that children whose mothers reported higher rates of perceived gendered racial stress during pregnancy and racial discrimination throughout their lifetime would have lower scores on executive functioning assessments. Furthermore, we hypothesized that low maternal education and income would act as risk moderators whereas social support would act as a protective moderator in the associations between maternal experiences of discrimination (EOD) and child executive functioning. Main effect findings support our hypothesis of an intergenerational association between maternal EOD and gendered racial stress and lower child executive functioning scores. Income was a significant moderator. As hypothesized, the association between mothers reports of lifetime discrimination and lower child executive functioning scores was stronger at lower levels of income. In contrast, however, the association between maternal prenatal reports of gendered racial stress and lower child executive functioning scores was stronger at higher levels of maternal education and income. Social support did not have a significant moderating effect on any of the association., (© 2025 Michigan Association for Infant Mental Health.)

Background: The facial artery musculomucosal (FAMM) flap is a versatile flap based on the facial artery. It can be used to reconstruct the floor of the mouth, palate, tongue and alveolar ridge. The flap can be designed in various orientations and modified as an islanded or tunnelised flap. This study aimed to review the application of FAMM flap in the reconstruction of defects of the tongue and oral cavity, with specific focus on success rates and total complications., Methods: A literature search was conducted by 2 independent reviewers on PubMed, Dynamed, DARE, EMBASE, Cochrane and British Medical Journal (BMJ) electronic databases (Registry CRD42024529989)., Results: Twenty-seven studies fulfilled the search criteria and data on 407 FAMM flaps performed on 402 patients were extracted for analysis. Overall, 1.7% (n=7) of flaps failed because of total necrosis (n=3), partial necrosis requiring surgical intervention and flap abandonment (n=2), total failure (n=1) and fistula formation (n=1). Overall, 26.0% (n=106) of patients experienced non-functional complications. The most reported complications were partial necrosis (n=23, 5.7%), wound dehiscence (n=18, 4.4%) and venous congestion (n=13, 3.2%). The pooled success rate in all studies using FAMM flaps for oral cavity and tongue reconstruction was 99.47% (95% CI, 98.26 to 100.00, P = 1.00; I 2 = 0%;). Pooled total complication rates were 30.18% (95% CI, 16.97 to 43.38, P < 0.01; I 2 = 91%). Only 35 flaps required re-operation., Conclusions: With low complication and failure rates, FAMM flaps are a safe and versatile option to consider in oral cavity and tongue reconstruction., (Copyright © 2025 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Aim: The British Thyroid Association (BTA) Guidelines for the Management of Thyroid Cancer advocate for fine-needle aspiration cytology for all thyroid nodules graded indeterminate (U3) at ultrasound assessment. This approach raises concerns regarding potential over-diagnosis of low-risk lesions. Conversely, equivalent Thyroid Imaging Reporting and Data Systems (TIRADS) guidelines permit surveillance or discharge of indeterminate thyroid nodules of certain sizes. This service analysis analyses how guideline choice impacts the fine-needle aspiration cytology rate and subsequent surgical management of indeterminate thyroid nodules., Materials and Methods: All patients with an indeterminate (U3) thyroid nodule identified on ultrasound over a 12-month period were included. Indeterminate thyroid nodules were retrospectively rescored using three equivalent TIRADS classifications by three independent reviewers, blinded to the histopathology. Hypothetical differences in fine-needle aspiration cytology rates and surgical activity were then compared., Results: Ninety-six nodules were identified. Retrospective application of TIRADS guidelines resulted in a hypothetical 44.8-55.2% reduction in fine-needle aspiration cytology performed for indeterminate thyroid nodules compared to BTA. A statistically significant increase in rates of surgical activity for indeterminate thyroid nodules was observed between BTA guidance and all retrospectively applied TIRADS guidelines (p < 0.001). Of four confirmed thyroid cancers, three would have been unanimously removed., Conclusion: Under BTA guidance, increased fine-needle aspiration cytology rates for indeterminate thyroid nodules resulted in significantly increased surgical activity in our cohort compared to retrospectively applied TIRADS guidelines., Competing Interests: Conflict of interest The authors declare no conflict of interest., (Copyright © 2024 The Royal College of Radiologists.

Surgical challenges in paediatric craniofacial and head and neck surgery can include operating in a small cavity, limited depth perception, restricted access with difficult angulations, and poor visualisation. Delicate tissue handling, muscle dissection, and suturing at depth require surgical access in congruence with the use of operative microscopes. Robotic assistance may aid surgeons in operating in confined spaces with minimal access incisions by improving the degree of freedom of operative instrumentation. In this study, we aim to review the use of robotic systems in paediatric head and neck and craniofacial surgery by focussing on total complications and length of surgery together with patient and surgeon experience. A literature search was conducted in June 2023 by two independent reviewers on Pubmed, Dynamed, DARE, EMBASE, Cochrane and British Medical Journal (BMJ) electronic databases for articles published between 1960-2024. Seventeen papers met the inclusion criteria. Seventy-nine patients were included. The success rate for head and neck and craniofacial cases that included robotic-assistance was 93.7% (n = 74) and the complication rate was 16.0% (n = 12). Robotic-assisted surgery demonstrates a low complication rate in treating a range of different pathologies in the head and neck in our included studies. Robotic-assistance in craniofacial surgery demonstrates promise in preventing iatrogenic injury from more traditional methods, and could allow for operations to proceed earlier in life in the management of midface distraction, however, more research in the area is necessary with limited research published at present., (Copyright © 2024 The British Association of Oral and Maxillofacial Surgeons.

Objective: BMI is commonly used to measure risk to prenatal health but may not be sensitive to adiposity-associated health problems for Black women. The aim of the present study was to test associations between indices of prenatal health and BMI in Black women., Methods: Data were from 652 women enrolled in two studies. Height and weight were used to calculate BMI. Depression and perceived stress were measured via maternal report, systemic inflammation via C-reactive protein (CRP), and nutrition by the ratio of omega-3 docosahexaenoic acid to omega-6 arachidonic acid fatty acids., Results: Neither perceived stress, depression, nor fatty acids were associated with prenatal BMI. CRP levels were positively associated with BMI (beta = 6.56, t = 13.30, p < .001). The prevalence of high-risk levels of CRP (> 3 mg/L) was below 10% for all weight classes except for BMI ≥ 40., Conclusions: Results suggest that BMI may not be a sensitive index of adiposity related risk to prenatal health for Black women., Competing Interests: Declarations Ethics Approval Approval for the informed consent processes and data collection protocols were granted by the Institutional Review Boards at the University of Pittsburgh and University of Atlanta. Consent to Participate Written Informed consent was obtained from all individual participants included in the study. Conflicts of Interest The authors report no conflict of interest., (© 2023. W.

Background: UK examining bodies are required to eliminate discrimination against people with protected characteristics. To achieve this in surgery, differential attainment (DA) in assessments used as gatekeepers to career progression must be ruled out. This study investigated the impact of disability status on the likelihood of success at national selection for Higher Surgical Training (HST)., Methods: A retrospective cohort study of all UK graduates in the UKMED database (https://www.ukmed.ac.uk) who underwent selection for HST (ST3) from 2012 to 2019 (n = 2875). Univariate analysis identified differences in success rates at first-application. Logistic regression models identified whether disability was a predictor of success after adjusting for sociodemographic factors and prior MRCS performance., Results: There was no significant difference in success rates between candidates with and without disabilities (all p > 0.05) for any surgical specialty. Disability status was not a statistically significant predictor of success. Female candidates were 25 % more likely to be successful (OR 1.25 [95%CI 1.05 to 1.49]) and Non-White candidates were 20 % less likely to be successful (OR 0.80 [95%CI 0.68 to 0.96]). Candidates who passed MRCS Part A and Part B at the first attempt were 49 % (OR 1.49 [95%CI 1.25 to 1.77]) and 90 % (OR 1.90 [95%CI 1.58 to 2.28]) more likely to be successful., Conclusion: No significant difference was found in the likelihood of being successful at HST selection for any surgical specialty between applicants with and without disabilities, regardless of type of disability. DA was identified between other sociodemographic groups which requires further exploration., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Studies have demonstrated the negative impact that work-related musculoskeletal disorders (WMSDs) have on surgeons. These are also likely to affect some allied healthcare professionals such as interventional radiologists. Problems from WMSDs include pain, diminished technical and cognitive performance, and work absence. These could contribute to burnout, to which surgeons are already vulnerable owing to other working practices such as shift patterns and long hours. WMSDs could negatively affect working performance, and lead to poorer surgical outcomes and patient care. Surgeons are at risk of WMSDs of the neck and back that result from fixed and damaging postures while operating. Some have reduced their operation numbers and working days as result of WMSDs. Theatre ergonomics (e.g. table positioning, operating stools and monitors), intraoperative breaks and stretching may improve WMSDs for some. Strength/resistance training (RT) may be used to prevent or mitigate WMSDs. RT can also enhance general health and concentration, and combat intraoperative fatigue. Low engagement times of moderate-intensity RT of 20 minutes, twice a week, improve neck and back pain from WMSDs. Moreover, RT has been shown to reduce all-cause mortality by up to 15%, increase bone density, improve proprioception and reduce the fear of movement due to pain. Alongside ergonomic improvement and stretching, we recommend RT as an activity to improve general health and WMSDs.

Early life adversity (ELA) and youth chronic health conditions have been examined as separate contributors to psychopathology. However, little work has specifically examined early life health adversity (ELHA) and its association with risk for internalizing disorders. This study seeks to examine the relationship between ELHA and internalizing disorders across adolescence. A sample of 705 Australian mother-youth dyads participated in a prospective longitudinal study. Mothers reported child health indicators at youth ages three-to-four days, six months, and five years and completed a psychiatric interview at 15 years. Youth completed a psychiatric interview, as well as measures of current health status, at age 20. ELHA was positively associated with both youth anxiety and depressive disorders from ages 15 to 20. When independently accounting for the role of (a) current health status and (b) exposure to traditionally conceptualized forms of ELA, these findings remained statistically significant for anxiety but not depressive disorders. ELHA interacted with maternal depression, such that ELHA was only associated with youth depressive disorders in cases where mothers themselves had experienced depression. Routine mental health screenings may be warranted for youth who experience ELHA and their mothers. Pediatric primary care may be an ideal setting for implementing prevention and intervention efforts.

Background: Childhood sleep quality is associated with physical, cognitive, and behavioral health and predicts later sleep quality; it has many determinants, including developmental exposures., Objectives: To examine associations between maternal stress during pregnancy and childhood sleep quality and determine whether postnatal stress mediates the association., Method: Data from the Environmental Influences on Child Health Outcomes cohort were used. Perceived Stress Scale (PSS) T-scores were the exposure measure. Outcome measures were preschool Child Behavior Checklist (CBCL) sleep syndrome scale and Patient-Reported Outcomes Measurement Information System Sleep Disturbance Parent Proxy short form 4a (PSD4a) T-scores at ages 4-8 years. Linear mixed-effects regression modeling was performed for each sleep outcome, adjusting for maternal age at delivery and education and child sex, gestational age at birth, and age at outcome ascertainment, with random intercepts for cohorts., Results: Prenatal PSS score was associated with both CBCL (B = 0.09, 95% confidence interval [CI]: 0.06, 0.11; p < 0.01) and PSD4a (B = 0.07, 95% CI: 0.03, 0.12; p < 0.01) scores. Postnatal perceived stress mediated a proportion of the total effect of prenatal stress in both CBCL (66.3%) and PSD4a (95.9%) samples., Conclusions: Both pre- and postnatal maternal perceived stress appear to influence sleep quality during early life., Impact: Prenatal stress significantly associates with child sleep problems and disturbances at ages 4-8 years; postnatal maternal stress is a significant mediator of these associations. Research suggests a range of prenatal affective/distress exposures associated with child sleep problems, but the conclusions remain in doubt due to the mixture of exposures and outcomes employed. Ours is the first US-based effort to explore associations between perceived maternal stress during pregnancy and child sleep problems and disturbance in early and middle childhood. Even a small effect of a prevalent issue like psychosocial stress may have important public health implications at the population level., (© 2024.

Second-degree students pursuing oral and maxillofacial surgery (OMFS) may be at particular risk of burnout when striving to find a balance between a full-time degree, locum work, and developing portfolios for specialist training applications. The current study aimed to explore self-reported burnout and identify risk factors for burnout amongst second-degree students considering a career in OMFS. An online survey was distributed via social media to second-degree students across the United Kingdom and 122 responses were received. A majority of students felt they had suffered from burnout during their second degree (n = 74, 60.7%). Burnout was more likely to be reported by students enrolled on a four-year dental degree (p = 0.016, OR 6.291, 95% CI: 1.402 to 28.235), by female students (p = 0.006, OR 5.791, 95% CI: 1.659 to 20.219), and those aged 28-30 (p = 0.032, OR 5.818, 95% CI: 1.165 to 29.054) or between 34 and 36 years (p = 0.008, OR 14.882, 95% CI 1.998 to 110.826). Students doing zero night shifts per month were significantly less likely to suffer from burnout compared with those doing more than six night shifts per month (p = 0.016, OR: 0.034, 95% CI: 0.002 to 0.537) or more than six day shifts per month (p = 0.028, OR: 15.272, 95% CI: 1.335 to 174.732). It may be possible to reduce the risk of burnout amongst second-degree students and enhance their wellbeing by improving financial and clinical development incentives as part of regular locum work opportunities, by providing access to tailored OMFS mentorship, and by streamlining training., (Copyright © 2024 The British Association of Oral and Maxillofacial Surgeons.

Background: The Modified Checklist for Autism in Toddlers (M-CHAT) is a common pediatric screening tool with mixed accuracy findings. Prior evidence supports M-CHAT screening for developmental concerns, especially in toddlers born preterm. This study examined M-CHAT accuracy in a large, nationwide sample., Methods: 3393 participants from the Environmental influences on Child Health Outcomes (ECHO) program were included. Harmonized M-CHAT (M-CHAT-H) results were compared with parent-reported autism diagnosis and autism-related characteristics to assess accuracy for term and preterm children, together and separately. Generalized estimating equations, clustering for ECHO cohort and controlling for demographic covariates, were used to examine associations between developmental and behavioral characteristics with M-CHAT-H accuracy., Results: Sensitivity of the M-CHAT-H ranged from 36 to 60%; specificity ranged from 88 to 99%. Positive M-CHAT-H was associated with more developmental delays and behavior problems. Children with severe motor delays and more autism-related problems were more likely to have a false-negative M-CHAT-H. Children with fewer behavior problems and fewer autism-related concerns were more likely to have a false-positive screen., Conclusion: The M-CHAT-H accurately detects children at low risk for autism and children at increased risk with moderate accuracy. These findings support use of the M-CHAT-H in assessing autism risk and developmental and behavioral concerns in children., Impact: Previous literature regarding accuracy of the Modified Checklist for Autism in Toddlers (M-CHAT) is mixed but this study provides evidence that the M-CHAT performs well in detecting children at low risk for autism and consistently detects children with developmental delays and behavioral problems. The M-CHAT moderately detects children at increased risk for autism and remains a useful screening tool. This study examines M-CHAT accuracy in a large-scale, nationwide sample, examining associations between screening accuracy and developmental outcomes. These findings impact pediatric screening for autism, supporting continued use of the M-CHAT while further elucidating the factors associated with inaccurate screens., (© 2024.

Background: Prenatal exposure to phthalates, a group of synthetic chemicals widely used in consumer products, has previously been associated with adverse infant and child development. Studies also suggest that maternal depression and anxiety, may amplify the harmful effects of phthalates on infant and child neurodevelopment., Study Design: Our analysis included a subset of dyads enrolled in the Atlanta African American Maternal-Child Cohort (N = 81). We measured eight phthalate metabolites in first and second trimester (8-14 weeks and 24-32 weeks gestation) maternal urine samples to estimate prenatal exposures. Phthalate metabolite concentrations were averaged across visits and natural log-transformed for analysis. Maternal symptoms of depression and anxiety were assessed using validated questionnaires (Edinberg Postnatal Depression Scale and State Trait Anxiety Inventory, respectively) and the total score on each scale was averaged across study visits. The NICU Network Neurobehavioral Scale (NNNS) was administered at two weeks of age. Our primary outcomes included two composite NNNS scores reflecting newborn attention and arousal. Linear regression was used to estimate associations between individual phthalate exposures and newborn attention and arousal. We assessed effect modification by maternal depression and anxiety., Results: Higher levels of urinary phthalate metabolites were not associated with higher levels of infant attention and arousal, but true associations may still exist given the limited power of this analysis. In models examining effect modification by maternal depression, we observed that an interquartile range increase in mono (2-ethlyhexyl) phthalate (MEHP), mono (2-ethyl-5-oxohexyl) phthalate (MEOHP), and mono (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) was associated with a significant increase in newborn arousal only among those with high depressive symptoms (MEHP: β = 0.71, 95% confidence interval [CI] = 0.10, 1.32 for high, β = -0.30, 95% CI = -0.73, 0.12 for low; MEOHP: β = 0.60, 95% CI = -0.03, 1.23 for high, β = -0.12, 95% CI = -0.58, 0.33 for low; MEHHP: β = 0.54, 95% CI = -0.04, 1.11 for high, β = -0.11, 95% CI = -0.54, 0.32 for low). Similar patterns were observed in models stratified by maternal anxiety, although CIs were wide., Conclusion: Our results suggest maternal anxiety and depression symptoms may exacerbate the effect of phthalates on infant neurodevelopment. Future studies are needed to determine the optimal levels of attention and arousal in early infancy., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Importance: Robust longitudinal studies of within-child changes in mental health associated with the COVID-19 pandemic are lacking, as are studies examining sources of heterogeneity in such changes., Objective: To investigate within-child changes, overall and between subgroups, in youth mental health from prepandemic to midpandemic., Design, Setting, and Participants: This cohort study used longitudinal prepandemic and midpandemic data from the Environmental influences on Child Health Outcomes (ECHO) Program, collected between January 1, 2015, and March 12, 2020 (prepandemic), and between March 13, 2020, and August 31, 2022 (midpandemic). Data were analyzed between December 1, 2022, and June 1, 2024. The sample included 9 US-based observational longitudinal pediatric ECHO cohorts. Cohorts were included if they collected the Child Behavior Checklist (CBCL) School Age version before and during the pandemic on more than 20 participants of normal birth weight aged 6 to 17 years., Exposure: The COVID-19 pandemic., Main Outcomes and Measures: Prepandemic to midpandemic changes in CBCL internalizing, externalizing, depression, anxiety, and attention-deficit/hyperactivity disorder (ADHD) scores were estimated, and differences in outcome trajectories by child sociodemographic characteristics (age, sex, race, ethnicity, and poverty level) and prepandemic mental health problems were examined using established CBCL clinical score thresholds., Results: A total of 1229 participants (mean [SD] age during the pandemic, 10.68 [2.29] years; 625 girls [50.9%]) were included. The sample was socioeconomically diverse (197 of 1056 children [18.7%] lived at ≤130% of the Federal Poverty Level; 635 (51.7%) identified as White, 388 (31.6%) as Black, 147 (12.0%) as multiracial, 40 (3.3%) as another race, and 118 (9.6%) as Hispanic). Generalized linear mixed-effects models revealed minor decreases in externalizing problems (β = -0.88; 95% CI, -1.16 to -0.60), anxiety (β = -0.18; 95% CI, -0.31 to -0.05), and ADHD (β = -0.36; 95% CI, -0.50 to -0.22), but a minor increase in depression (β = 0.22; 95% CI, 0.10 to 0.35). Youth with borderline or clinically meaningful prepandemic scores experienced decreases across all outcomes, particularly externalizing problems (borderline, β = -2.85; 95% CI, -3.92 to -1.78; clinical, β = -4.88; 95% CI, -5.84 to -3.92). Low-income (β = -0.76; 95% CI, -1.14 to -0.37) and Black (β = -0.52; 95% CI, -0.83 to -0.20) youth experienced small decreases in ADHD compared with higher income and White youth, respectively., Conclusions and Relevance: In this longitudinal cohort study of economically and racially diverse US youth, there was evidence of differential susceptibility and resilience for mental health problems during the pandemic that was associated with prepandemic mental health and sociodemographic characteristics.

This study examined the association between prenatal cannabis exposure and autism spectrum disorder (ASD) diagnoses and traits. A total sample of 11,570 children (ages 1-18; 53% male; 25% Hispanic; 60% White) from 34 cohorts of the National Institutes of Health-funded environmental influences on child health outcomes consortium were included in analyses. Results from generalized linear mixed models replicated previous studies showing that associations between prenatal cannabis exposure and ASD traits in children are not significant when controlling for relevant covariates, particularly tobacco exposure. Child biological sex did not moderate the association between prenatal cannabis exposure and ASD. In a large sample and measuring ASD traits continuously, there was no evidence that prenatal cannabis exposure increases the risk for ASD. This work helps to clarify previous mixed findings by addressing concerns about statistical power and ASD measurement., (© 2024 International Society for Autism Research and Wiley Periodicals LLC.)

Background: African Americans (AAs) experience higher rates of preterm birth and fetal growth restriction relative to other pregnant populations. Differential in utero exposure to environmental chemicals may partially explain these health disparities, as AAs are disproportionately exposed to environmental hazards., Objective: We examined the individual and mixture effects of non-persistent chemicals and persistent organic pollutants (POPs) on gestational age at birth and birthweight for gestational age z-scores within a prospective cohort of pregnant AAs., Methods: First-trimester serum and urine samples obtained from participants within the Atlanta African American Maternal-Child cohort were analyzed for 43 environmental chemicals, including per-and polyfluoroalkyl substances (PFAS), polybrominated diphenyl ethers (PBDEs), organochlorine pesticides, pyrethroid insecticides, phthalates, bisphenol A, nicotine, and the primary metabolite of delta-9-tetrahydrocannabinol. Linear regression was used to estimate individual associations between chemicals and gestational age and birthweight z-scores (N ranging from 107 to 523). Mixture associations were estimated using quantile g-computation, principal component (PC) analyses, and hierarchical Bayesian kernel machine regression among complete cases (N = 86)., Results: Using quantile g-computation, increasing all chemical exposures by one quantile was modestly associated with a reduction in gestational age (mean change per quartile increase = -0.47, 95% CI = -1.56, 0.61) and birthweight z-scores (mean change per quartile increase = -0.49, 95% CI = -1.14, 0.15). All PCs were associated with a reduction in birthweight z-scores; associations were greatest in magnitude for the two PCs reflecting exposure to combined tobacco, insecticides, PBDEs, and phthalates. In single pollutant models, we observed inconsistent and largely non-significant associations., Signifance: We conducted multiple targeted exposure assessment methods to quantify levels of environmental chemicals and leveraged mixture methods to quantify their joint effects on gestational age and birthweight z-scores. Our findings suggest that prenatal exposure to multiple classes of persistent and non-persistent chemicals is associated with reduced gestational age and birthweight z-scores in AAs., Impact: African Americans (AAs) experience higher rates of preterm birth and fetal growth restriction relative to other pregnant populations. Differential in utero exposure to environmental chemicals may partially explain these health disparities, as AAs are disproportionately exposed to environmental hazards. In the present study, we analyzed serum and urine samples for levels of 43 environmental chemicals. We used quantile g-computation, principal component analysis, and BKMR to assess associations between chemical exposure mixtures and adverse birth outcomes. Our findings suggest that prenatal exposure to multiple classes of chemicals is associated with reduced birthweight z-scores, a proxy for fetal growth, in AAs., (© 2023.

Background: Differential exposure to chronic stressors by race/ethnicity may help explain Black-White inequalities in rates of preterm birth. However, researchers have not investigated the cumulative, interactive, and population-specific nature of chronic stressor exposures and their possible nonlinear associations with preterm birth. Models capable of computing such high-dimensional associations that could differ by race/ethnicity are needed. We developed machine learning models of chronic stressors to both predict preterm birth more accurately and identify chronic stressors and other risk factors driving preterm birth risk among non-Hispanic Black and non-Hispanic White pregnant women., Methods: Multivariate Adaptive Regression Splines (MARS) models were developed for preterm birth prediction for non-Hispanic Black, non-Hispanic White, and combined study samples derived from the CDC's Pregnancy Risk Assessment Monitoring System data (2012-2017). For each sample population, MARS models were trained and tested using 5-fold cross-validation. For each population, the Area Under the ROC Curve (AUC) was used to evaluate model performance, and variable importance for preterm birth prediction was computed., Results: Among 81,892 non-Hispanic Black and 277,963 non-Hispanic White live births (weighted sample), the best-performing MARS models showed high accuracy (AUC: 0.754-0.765) and similar-or-better performance for race/ethnicity-specific models compared to the combined model. The number of prenatal care visits, premature rupture of membrane, and medical conditions were more important than other variables in predicting preterm birth across the populations. Chronic stressors (e.g., low maternal education and intimate partner violence) and their correlates predicted preterm birth only for non-Hispanic Black women., Conclusions: Our study findings reinforce that such mid or upstream determinants of health as chronic stressors should be targeted to reduce excess preterm birth risk among non-Hispanic Black women and ultimately narrow the persistent Black-White gap in preterm birth in the U.S., (© 2024.

Study Design: Systematic Review and Meta-Analysis., Objective: There has been an increasing trend in maxillofacial injuries associated with combat trauma. Within the maxillofacial complex, the mandible is the most likely structure to be damaged during combat. The structural deficits as a result can be reconstructed with many options. These include vascularised bone grafts (VBGs), non-vascularised bone grafts (NVBGs), alloplastic implants, reconstruction bars and distraction osteogenesis. This study aimed to determine the common modality and efficacy of mandibular reconstruction in combat trauma-related defects., Methods: A literature search was conducted on Pubmed, Prospero, Dynamed, DARE, EMBASE, COCHRANE and BMJ databases., Results: A total of six articles met the inclusion criteria identifying 165 patients requiring mandibular reconstruction. Non-vascularised iliac bone graft (n = 137) was the most common method followed by ileac crest bone chips harvest using Dacron urethran osteomesh tray (n = 24) and frontoparietal grafts (n = 4). Meta-analysis of five out of six trials demonstrated an overall success rate of 85% (95% CI 79-90; I 2 = 59%). A total of 13% (n = 22) of reconstructions failed either completely or partially and 21% (n = 34) of patients suffered postoperative complications., Conclusions: NVBGs are a practical, cost-effective and favourable method of war zone management of mandibular defects with success rates comparable to those reported in the civilian literature. However, general trauma principles take precedence to rule out life-threatening injuries. Due consideration of patient factors, surgical factors, and available resources are required in the first-line management of combat-related mandibular defects., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Background: The Intercollegiate Membership of the Royal College of Surgeons (MRCS) examination is a mandatory requirement for higher specialty surgical training in the UK. However, there is a significant economic impact on trainees which raises the question of whether the costs of this exam hinder surgical career progression. This study explores the burden of these exams on trainees., Methods: A 37-point questionnaire was distributed to all trainees who were preparing for or have sat MRCS examinations. Univariate analyses included the cost of the preparatory resources, extra hours worked to pay for these and the examinations, and the number of annual leave (AL) days taken to prepare. Pearson correlation coefficients were used to identify possible correlation between monetary expenditure and success rate., Results: On average, trainees (n ​= ​145) spent £332.54, worked 31.2 ​h in addition to their rostered hours, and used 5.8 AL days to prepare for MRCS Part A. For MRCS Part B/ENT, trainees spent on average £682.92, worked 41.7 extra hours, and used 5 AL days. Overall, the average trainee spent 5-9% of their salary and one-fifth of their AL allowance to prepare for the exams. There was a positive correlation between number of attempts and monetary expenditure on Part A preparation (r(109)=0.536, p ​< ​0.001)., Conclusions: There is a considerable financial and social toll of the MRCS examination on trainees. Reducing this is crucial to tackle workforce challenges that include trainee retention and burnout. Further studies exploring study habits can help reform study budget policies to ease this pressure on trainees., Competing Interests: Declaration of competing interest None to declare., (Copyright © 2024 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Prenatal cannabis use and maternal stress have been proposed as risk factors for autism spectrum disorder (ASD). Black mothers and mothers of lower socioeconomic status (SES) may be especially likely to experience high levels of stress. This study examined the impact of prenatal cannabis use and maternal stress (i.e., prenatal distress, racial discrimination, and lower SES) on child ASD-related behaviors in a sample of 172 Black mother-child pairs. We found that prenatal stress was significantly associated with ASD-related behaviors. Prenatal cannabis use did not predict ASD-related behaviors and did not interact with maternal stress to predict ASD-related behaviors. These findings replicate previous work on prenatal stress-ASD associations and add to the limited literature on prenatal cannabis-ASD associations in Black samples., (© 2023. The Author(s).)

Objective: To examine the additive or moderating influences of caregiver COVID-19-related stress, social support, and discrimination on children's behavior problems across racially diverse populations., Method: In this Environmental influences on Child Health Outcomes (ECHO) cohort study (N = 1,999 caregiver/child pairs), we operationalized caregiver COVID-19-related stress in 2 ways: first, as the number of stressors (eg, financial concerns, social distancing); and second, as the level of pandemic-related traumatic stress symptoms reported via questionnaires administered between April 2020 and August 2022. At the same assessment visit, caregivers also reported their current levels of discrimination, and a subsample (n = 968) reported their emotional and instrumental support. Either concurrently or at a later assessment visit, caregivers reported on their children's internalizing and externalizing behavior problems using the Child Behavior Checklist for Ages 6-18 (CBCL/6-18)., Results: Multivariable analyses controlling for maternal education, marital status, child age, and child sex revealed that COVID-19-related stress (caregiver stressors and symptoms) and discrimination were positively associated, and that perceived support was negatively associated with child internalizing and externalizing behavior problems. Unexpectedly, neither emotional nor instrumental support attenuated the relationship between caregiver COVID-19-related stressors nor traumatic stress symptoms and child behavior problems. In the subset of Black American participants, caregiver perceived discrimination moderated the relationship between caregiver COVID-19 traumatic stress symptoms and child internalizing problems, such that the association was stronger at higher levels of discrimination., Conclusion: Our findings highlight the potential importance of relieving caregiver stress and increasing caregiver social support to optimize children's behavioral outcomes., (Copyright © 2023 American Academy of Child and Adolescent Psychiatry.

Objective: We sought to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on perinatal outcomes while accounting for maternal depression or perceived stress and to describe COVID-specific stressors, including changes in prenatal care, across specific time periods of the pandemic., Study Design: Data of dyads from 41 cohorts from the National Institutes of Health Environmental influences on Child Health Outcomes Program ( N  = 2,983) were used to compare birth outcomes before and during the pandemic ( n  = 2,355), and a partially overlapping sample ( n  = 1,490) responded to a COVID-19 questionnaire. Psychosocial stress was defined using prenatal screening for depression and perceived stress. Propensity-score matching and general estimating equations with robust variance estimation were used to estimate the pandemic's effect on birth outcomes., Results: Symptoms of depression and perceived stress during pregnancy were similar prior to and during the pandemic, with nearly 40% of participants reporting mild to severe stress, and 24% reporting mild depression to severe depression. Gestations were shorter during the pandemic ( B  =  - 0.33 weeks, p  = 0.025), and depression was significantly associated with shortened gestation ( B  =  - 0.02 weeks, p  = 0.015) after adjustment. Birth weights were similar ( B  =  - 28.14 g, p  = 0.568), but infants born during the pandemic had slightly larger birth weights for gestational age at delivery than those born before the pandemic ( B  = 0.15 z-score units, p  = 0.041). More women who gave birth early in the pandemic reported being moderately or extremely distressed about changes to their prenatal care and delivery (45%) compared with those who delivered later in the pandemic. A majority (72%) reported somewhat to extremely negative views of the impact of COVID-19 on their life., Conclusion: In this national cohort, we detected no effect of COVID-19 on prenatal depression or perceived stress. However, experiencing the COVID-19 pandemic in pregnancy was associated with decreases in gestational age at birth, as well as distress about changes in prenatal care early in the pandemic., Key Points: · COVID-19 was associated with shortened gestations.. · Depression was associated with shortened gestations.. · However, stress during the pandemic remained unchanged.. · Most women reported negative impacts of the pandemic.., Competing Interests: C.M. served as Chair of the Data Safety Monitoring Board (DSMB) for an Aerogen-supported trial: A Partially-Blind, Randomized, Controlled, Parallel-Group Dose Ranging Study to Determine the Efficacy, Safety and Tolerability of AeroFactTM (SF-RI 1 surfactant for inhalation combined with a dedicated drug delivery system) in Preterm Infants at Risk for Worsening Respiratory Distress Syndrome; Chair of the DSMB for the NIH RCT evaluating Sildenafil in Preterm Infants with Pulmonary Hypertension.

The chance of death from medical error within the hospital setting is 33,000 times greater than dying in an aircraft crash. Despite patient safety being central to healthcare delivery across the world, medical errors and patient harm remain prevalent. This review evaluates the role of the criminal law in regulating healthcare across England and Wales, using prior legal case studies, and focussing on the offence of gross negligence manslaughter (GNM). It further examines the extent to which the law promotes patient safety and minimises fatal errors in healthcare. Medical negligence resulting in a patient's death invokes the more punitive criminal law. In the context of the legal framework in England and Wales, individuals, including medical professionals, who are found to have caused a fatality due to 'gross negligence' may potentially be subject to manslaughter charges. Healthcare delivery is complex as it involves working in high-risk environments, invariably as part of a team. When things go wrong, it is rarely the result of an individual's error but rather a systemic failure. Human factors that may contribute to GNM include organisational influences such as trust targets and pressures to deliver results, unsafe supervision, or inadequate staffing, and preconditions for unsafe acts whereby clinicians are fatigued whilst performing multiple roles simultaneously. A more just culture is warranted in response to the criminalisation of cases of healthcare malpractice, in particular those involving GNM, in which healthcare professionals would be able to learn without fear of retribution., (Copyright © 2023 The Author(s).

Scapular tip flaps (STF) may be used as an alternative to traditional methods of reconstruction of head and neck cancer (HNC) defects. This study aimed to establish the success and complication rates for STF in HNC reconstruction. A literature search was conducted on PubMed, BMJ Journals, DARE, EMBASE databases and Cochrane (CENTRAL) register. (Registry CRD42023428012). A total of 23 studies fulfilled the inclusion criteria with 474 patients who underwent reconstructive procedures using the STF. 100% of STF used were free flaps (STFFs). The most common reason for reconstruction was following malignancy (81.4%, n = 386). The pooled success rates in all studies using scapular tip flaps in head and neck reconstruction was 99% (95% CI, 97 to 100, p = 1.00; I2 = 0). Pooled total complication rates were 38% (95% CI, 25 to 51, p < 0.01; I2 = 90%). 19.6% required return to theatre with only 1.5% being for repeat flap coverage. The STF demonstrated an overall success rate of 99%. This is higher than other documented success rates with mainstay flaps for HNC defect reconstruction. Complication and re-operation rates were also like recorded rates. This review demonstrates the advantage of STF as a safe and versatile reconstructive option for HNC related defects. Evaluation of the literature is limited by poor-quality studies and comparability bias., (Copyright © 2023 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Recent discourse around the implementation of medical associate professions (MAPs) into medical specialties has proven divisive and controversial. These roles could benefit oral and maxillofacial surgery (OMFS) departments and grant trainees increased operating experience, but their implementation could prove detrimental to training. We discuss the potential impact in OMFS., (Copyright © 2023 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.)
