Growing evidence has linked both the onset and symptoms of various mental disorders to lifestyle factors such as diet, exercise and sleep. The link between diet and mental health, in particular in depressive disorders, has gained interest in recent years. Previous reviews assessing the link between the Mediterranean diet (MedDiet) and mental health predominantly focused on depression, whilst others failed to integrate a summary of possible underlying mechanisms related to a link between MedDiet and mental health to complement their findings. In the present review, we provide a comprehensive synthesis of evidence on the MedDiet and diverse mental health outcomes complemented by narration of the potential mechanisms involved. A literature search was conducted across MEDLINE, PsycINFO, Scopus, Cochrane library, Google Scholar, CINAHL and Embase databases. A total of 10 249 articles were found through the primary literature search and 104 articles (88 observational and 16 interventional studies) were eligible for inclusion. The MedDiet has been associated with favourable mental health outcomes in adult populations, including reduced depressive and anxiety symptoms, lower perceived stress, and improved quality of life and overall wellbeing, both in healthy individuals and those with comorbidities, across diverse geographical settings. Mechanisms involved include the antioxidant, anti-inflammatory potential of the MedDiet and its effect on gut microbiota. Further research is warranted to rigorously establish causal inferences and to guide the optimal incorporation of Mediterranean diet principles into comprehensive prevention and treatment strategies aimed at improving mental health outcomes.
The study aimed to utilise internet big data to quantify the taste preferences of residents in Fujian Province and to explore the relationship between dietary taste preferences and hospitalisation rates for digestive system cancers.
Design:
The study employed an associative design using internet big data to analyse dietary behaviour and its association with hospitalisation rates for digestive system cancers. GeoDetector methods were used to compare the association between rural residents’ hospitalisation rates and their taste preferences.
Setting:
This study utilised internet recipe data to collect cuisines taste information. By integrating this with categorised restaurant data from point of interest sources across various regions in Fujian province, it quantitatively analysed the regional taste preferences of people.
Participants:
Data from seventy-two counties in Fujian cover most of the province. Included 154 686 hospitalisation records for digestive system cancers (2010–2016) from the New Rural Cooperative Medical Scheme database, 16 363 recipes from Internet and data from 30 984 restaurants through Amap.
Results:
The study found pungent to be the prevalent taste in Fujian, with salty, spicy and sour following. Coastal areas favoured stronger tastes. Spatial analysis showed taste preferences clustered geographically, with Sour and Fat tastes having an association with liver and colorectal cancer (CC) hospitalisations, though with modest association values (0·110–0·199).
Conclusions:
The study found significant spatial clustering of taste preferences in Fujian Province and an association between Sour and Fat tastes preference and hospitalisation rates for liver and CC, suggesting a dietary taste–cancer link.
Shoulder dystocia is defined as a vaginal cephalic delivery that requires additional obstetric manoeuvres to deliver the fetus after the head has been delivered and gentle downward traction has failed. Shoulder dystocia occurs when the anterior fetal shoulder, or less commonly the posterior shoulder, impacts on the maternal symphysis or the sacral promontory, respectively, preventing the delivery of the fetal body after the head has been delivered. The average gynaecoid pelvis at the inlet is 12cm in the anteroposterior diameter and 13cm in the transverse dimeter. The biacromial diameter of an average sized fetus is about 12-15cm. The shoulders usually traverse the pelvic inlet in the larger transverse diameter, though the biacrominal diameter is often larger the transverse diameter, there is usually no obstruction because the shoulders are compressible. Shoulder dystocia usually occurs when the fetal shoulders do not rotate to the wider oblique pelvic diameter. The incidence of shoulder dystocia in the largest case series ranges between 0.2% and 0.7%.
Preterm birth (PTB) is the leading cause of perinatal mortality and morbidity. The long-term health problems associated with PTB are significant. Despite many strategies to identify and treat preterm birth and labour, there remains slow progress in reducing the rates of PTBs. The causes of PTBs are multifactorial. There needs to be a good and coordinated approach to the identification of risk factors, screening strategies and appropriate interventions to have any impact on reducing the rates of PTBs worldwide. Currently, there is no single diagnostic test that should be used exclusively to direct management in the setting of threatened preterm labour. Tests to stratify risks of PTB include biochemical markers such as fetal fibronectin and transvaginal ultrasound of cervical length. Common interventions for preterm labour include tocolysis, antenatal corticosteroids and magnesium sulphate for neuroprotection. This chapter analyses the causes and risk factors for PTB, screening strategies and preventative initiatives to prevent PTB, and reviews the evidence and current guidelines in the screening and prevention of PTB.
In basic neuropsychopharmacological research, some biobehavioural phenomena — e.g., population migration and navigation over long distances — are rarely considered because the most commonly used laboratory animals show little or no evidence of these phenomena. Nevertheless, they can be also relevant for the mechanism of human psychic aberrations. An annual migration is seen in migratory birds, certain marine mammals and several ungulates. For migratory birds, the time of departure is determined by the length of the photoperiod and is much less changeable than the chosen route. When navigating, migratory birds also use the direction and strength of the field lines of the Earth’s magnetic field. Because humans also seem to exhibit a certain sensitivity to the Earth’s magnetic field, the regulation in birds could also provide hints for research on human well-being. Some bird species have such highly developed cognitive abilities that this is considered proof of the possession of consciousness. Therefore, some birds may be suitable as experimental animals in neurobiological models for cognitive functions and for making the world of thought accessible. The dorsal diencephalic conduction system (DDCS) in humans is difficult to study due to its small size and complex architecture, but it is relatively well developed in more primitive vertebrates. For research into the primary interactions between the DDCS and the rest of the brain, the lamprey can be used as laboratory animal. There is manifold evidence that the DDCS along with forebrain and upper brainstem is of functional relevance and the significance of the DDCS in cortical-controlled networks could then be investigated in birds and verified in humans.
External auditory exostosis (surfer’s ear) is a progressive condition of benign hyperostotic overgrowths of the external auditory canal, secondary to repetitive cold-water exposure, in which symptoms correlate to degree of exostosis. Surgical intervention is the only available treatment, most commonly using the osteotome or microdrill, but these carry a risk of sensorineural hearing loss, post-operative stenosis, temporomandibular dysfunction and tympanic membrane perforation.
Methods
We describe in detail the Swansea technique, an innovative method of canaloplasty with endoscopic underwater excision of exostoses using a piezoelectric saw and continuous irrigation with 1:1,000,000 adrenaline, with the results from our first 34 procedures.
Results
The inherent properties of the piezoelectric saw reduce the risk of overall complications when compared with traditional methods, whilst the surgical set-up is cost-equivocal and easily implemented in departments with endoscopic capabilities.
Conclusion
The piezoelectric saw is a promising novel technique for the treatment of external auditory exostosis.
Early intervention (EI) for first-episode psychosis (FEP) mainly focuses on adolescents and young adults. Previous evaluation demonstrated superiority of 2-year EI program (EASY) over standard care in outcome improvement in young people (15–25 years) with FEP in Hong-Kong. However, effectiveness of territory-wide extended EASY, which provides 3-year EI service also to adult patients aged ≥26 years, has not been systematically examined.
Methods
This study adopted historical control–case design, comparing patients aged 26–55 years who had received extended EI (EI-group, n = 160) with those managed by standard psychiatric care (SC-group, n = 160) prior to an implementation of extended EI service on a comprehensive range of outcomes encompassing duration of untreated psychosis (DUP), pathway to care, symptom severity, psychosocial functioning, subjective quality of life and service utilization over 3 years of psychiatric follow-up, using systematic medical-record review and follow-up interview assessment.
Results
Our results showed that EI-group had significantly shorter DUP than SC-group. Additionally, EI-group displayed fewer average positive symptoms in the first and second year of follow-up, lower levels of negative and depressive symptoms, better global and social functioning, and higher quality of life on physical domain than SC-group at 3 years of follow-up. Our findings indicate that adult FEP patients receiving 3-year extended EI service had better clinical and functional outcomes than those managed by standard psychiatric care.
Conclusions
Our results thus provide real-world evidence supporting the superiority and implementation of 3-year extended EASY program for adult FEP patients in shortening of treatment delay and improvement of symptom and functional outcomes.
Hypoplastic left heart syndrome is considered one of the most severe CHDs and occurs in approximately 2–3% of all CHD cases. Hybrid procedures have been introduced as an alternative to traditional surgical techniques, such as the Norwood procedure, particularly for neonates at high risk. Although hybrid approaches claim to reduce surgical risks and improve recovery, little is known regarding their comparative effectiveness and safety. This review aims to describe the contribution of hybrid procedures in hypoplastic left heart syndrome management regarding survival rates, postoperative complications, and quality of life, through recovery outcomes and long-term results, in light of conventional surgical techniques.
Methods:
A systematic review was carried out following the PRISMA guidelines. Data were retrieved from PubMed, Scopus, Web of Science, and Cochrane Library. The search articles were published from January 2014 to November 2024. Inclusion was focused on paediatric patients diagnosed with hypoplastic left heart syndrome and studies comparing hybrid procedures versus traditional surgical methods. All screening, data extraction, and quality assessment were done by two independent reviewers.
Results:
This review analysed data from 11 studies comprising 934 neonates with hypoplastic left heart syndrome, of whom 371 underwent hybrid procedures (HP) and 563 received the Norwood procedure. The findings demonstrated that both approaches achieved comparable survival rates at 1, 3, and 5 years. Hybrid procedures were linked to slightly earlier interventions (standardised mean difference = −0.10, 95% confidence interval: −0.61 to 0.41, p = 0.77) and were favored for high-risk neonates due to reduced invasiveness. However, hybrid procedures showed a higher rate of interstage events (risk ratio = 0.81), 95% confidence interval: −0.62 to 2.25, p = 0.09) and higher rates of pulmonary artery stenosis requiring reinterventions (30% vs. 18% for Norwood). Norwood procedures were associated with fewer reinterventions and lower interstage event rates, highlighting their effectiveness for stable patients.
Conclusions:
Hybrid procedures offer a practical alternative to the Norwood procedure, especially for high-risk neonates. Although both approaches show similar long-term survival rates, hybrid procedures are associated with a higher risk of complications, including increased interstage mortality. These challenges highlight the need for continued advancements to refine hybrid techniques and to improve long-term outcomes. This review emphasises the critical role of tailored patient selection and calls for further research to enhance hybrid procedure protocols and optimise their effectiveness for specific patient populations.
Early life, or the neonatal period, is perhaps the most challenging time for ruminant livestock, as they adapt to the extra-uterine environment, undergo important physiological maturation, and navigate harsh ambient conditions. Maternal influences during gestation, especially energy and protein nutrition in late pregnancy, can alter many processes that affect the neonatal period. These processes include fetal growth and development, gestation length, difficulty of parturition, and maternal behavior, which interact to affect offspring vigor at birth. Moreover, colostrum and early milk production and composition are affected by gestational nutrition, and these along with the previous factors affect the neonate’s ability to obtain transfer of passive immunity, thermoregulate, perform basal metabolism, and ultimately survive to weaning. Often, the long-term effects of maternal nutrition during gestation on offspring are attributed solely to the prenatal environment, but it is critical to also consider influences of early life on later productivity and health. More research is needed to integrate these neonatal outcomes with prenatal and postnatal mechanisms as well as later ruminant livestock performance. Better understanding of the maternal environment’s effects on the neonatal period provides opportunity for improved management of ruminant livestock dams and offspring.
Children with coeliac disease (CD) on a gluten-free diet (GFD) often have poor dietary quality (DQ). A Gluten-Free Food Guide (GFFG) was developed to address this. This pilot randomised controlled trial evaluated the impact of GFFG dietary counselling on DQ and ultra-processed food (UPF) intake in newly diagnosed CD children. Child–parent pairs were randomised to the standard of care only (CON: n 20) or the intervention (INT: standard of care + GFFG; n 20). Primary outcomes included DQ (Healthy Eating Index-Canadian) and UPF intake (NOVA classification), assessed at baseline (BL), 3 and 6 months. In INT, dietary variety scores, a subcomponent of DQ, increased between BL and 3 months (BL: 6·7 (3·3–6·7) v. 3 months: 10 (10–10); P = 0·01) and in higher variety scores than CON at 3 months (P < 0·01). Total DQ and UPF intake remained unchanged. Increased dietary variety in INT was associated with increases in dairy products (BL: 7·5 (sd 3·6) % v. 3 months: 12·4 (sd 6·7) %; P = 0·01) and unsweetened milk (BL: 2·5 (sd 2·2) % v. 3 months: 4·7 (sd 3·0) %; P = 0·01) servings, consumed as a percentage of the total food group servings. These improvements were not observed at 6 months. A greater number of INT children met the GFFG protein recommendation at 3 months (BL: 0/19 v. 3 months: 5/19; P = 0·01), with no change in CON. A single GFFG session improved short-term dietary variety and unsweetened milk intake. Ongoing work addressing the GF food environment, dietitian access and policies to improve DQ are needed.
The aim of this study was to compare KTP (potassium titanyl phosphate) laser therapy and dextracin ear drops for treatment of chronic myringitis.
Methods
A case series involving 31 patients (18 laser group; 13 dextracin group). Primary outcomes included otorrhoea resolution, improvement in Chronic Ear Survey scores and endoscopic resolution. Secondary outcomes included hearing outcome and complications. Statistical analyses were performed using Mann-Whitney U, Wilcoxon signed-rank and Fisher’s exact tests.
Results
The laser group had a higher rate of otorrhoea resolution 66.67 per cent (n = 12) vs 15.38 per cent (n = 2) (p = 0.006), showed significant improvement in symptom scores (median 31.43; p = 0.005) and medical resource use (16.67; p < 0.001) and had a significant myringitis area reduction of 31.84 per cent (p < 0.001). No significant differences were observed in Chronic Ear Survey scores and area reduction in the dextracin group. One laser-group patient developed a permanent perforation.
Conclusion
KTP laser therapy is effective for refractory chronic myringitis, offering superior symptom relief and reduced healthcare utilisation compared to topical treatment.
Reading is a complex cognitive process requiring the integration of orthographic, phonological, and semantic information. The visual word form area, located in the ventral occipitotemporal cortex, is critically involved in orthographic decoding, and damage to this region is known to cause alexia. In contrast, the contributions of white matter pathways supporting reading are less well understood.
Method:
We present a unique neurosurgical case undergoing awake brain surgery for resection of a metastasis in the left occipitotemporal cortex. A tubular retractor was used to access the lesion and during the insertion of the retractor the patient underwent careful, continuous neuropsychological testing, including evaluation of reading. fMRI language mapping and diffusion MRI were performed preoperatively. Postoperative neuropsychological testing was completed two weeks after surgery to assess cognitive outcome.
Results:
The patient developed an alexia with letter-by-letter reading in real time during insertion of the tubular retractor. Stealth imaging enabled localization of the tubular retractor at the exact onset of the alexia and, by correlating this with tractography, showed that the tubular retractor was in the vertical occipital fasciculus (VOF).
Conclusions:
We present the first detailed case report linking the VOF to the acute onset of alexia observed intraoperatively during awake brain surgery. We discuss the connectomics of reading and possible contributions of the VOF in reading.

Nutraceuticals are increasingly of interest in nutritional psychiatry, where creatine has been investigated in several randomised trials for its effects on depressive symptoms. However, these findings have not yet been systematically synthesised. We conducted a systematic review to assess the effects of creatine supplementation on symptoms of depression. Four databases were searched up to February 2025 for trials comparing creatine with placebo in individuals with or without depression. Study selection, data extraction and risk of bias assessment (RoB 2) were conducted independently, and certainty of evidence was evaluated using Grading of Recommendations, Assessment, Development and Evaluation (GRADE). Random-effects meta-analyses with Hartung–Knapp–Sidik–Jonkman adjustment including eleven trials (1093 participants) found a standardised mean difference of −0·34 (95 % CI −0·68, −0·00; GRADE: very low quality of evidence), equivalent to 2·2 points on the seventeen-item Hamilton Depression Rating Scale, below the minimal important difference of 3·0 points. CI include non-clinically important effects, and heterogeneity was substantial (I2 = 71·3 %). While effects appeared larger in clinically depressed populations, subgroup analyses and trim-and-fill adjustments indicated substantial bias favouring creatine. Results for secondary endpoints were significant for remission (three trials, OR 3·60; 95 % CI 1·76, 7·56), but not for treatment response (two trials, OR 0·72; 95 % CI 0·28, 1·88). Our findings suggest that creatine may offer a small-to-moderate benefit for individuals with depression, but average effects were not clinically important and the true effect may be trivial or null. The evidence on which these results are based is very uncertain. Larger, more rigorous randomised trials are required to draw definitive conclusions.
Firearm violence remains a critical public health issue in the United States, disproportionately impacting youth and communities of color while imposing significant emotional and economic costs. Hospital-Based Violence Intervention Programs (HVIPs) have emerged as effective, multidisciplinary strategies with the goal of interrupting cycles of violence by providing trauma-informed care and community services initiated during hospitalization. To develop a strong HVIP, it is imperative to collaborate with local stakeholders, and the aim of this study was to create and evaluate the effectiveness of a novel approach to the creation of a community advisory board (CAB) for a local HVIP.
Methods:
This study presents a novel approach to the creation of a CAB to inform an HVIP in Houston, Texas. The CAB included diverse stakeholders such as community leaders, youth advocates, healthcare professionals, law enforcement professionals, and people with firearm violence lived experiences. Using a modified Intervention Mapping (IM) framework and the Community and Stakeholder Engagement Studio (CSES) model, the CAB convened through a series of structured meetings to identify community priorities, define modifiable risk factors, and inform HVIP programming.
Results:
CAB engagement led to the identification and development of key HVIP program components. The collaborative process emphasized transparency and mutual respect, fostering trust and increasing the likelihood of program acceptance and sustainability. CAB feedback was instrumental in shaping both short- and long-term implementation strategies.
Conclusion:
Integrating equitable, community-driven stakeholder engagement into HVIP development enhances cultural relevance and responsiveness. This approach not only strengthens program design but also builds community trust.
A case of a 3-year-old asymptomatic male patient, who previously lost two brothers and was found to have a homozygote ryanodine receptor 2 gene mutation, is presented. The patient’s initial electrocardiogram showed right bundle branch block, first-degree AV block, and left anterior hemiblock (trifascicular block), and echocardiographic examination revealed increased trabeculation in the left ventricle. Since the patient’s mother and father were consanguineous, a homozygous missense mutation was detected in the ryanodine receptor type 2 gene within the scope of clinical exome sequencing in the genetic test performed. Considering the family history, a dual-chamber epicardial implantable cardioverter-defibrillator implantation was performed. This case highlights the treatment process of a patient with a significant family history and a ryanodine receptor type 2 gene mutation, commonly associated with catecholaminergic polymorphic ventricular tachycardia, aiming to raise awareness of the disease.
This editorial discusses the common practice of using normality tests as a preliminary step for choosing between parametric and non-parametric methods. The editorial argues that such pre-testing is theoretically unfounded and practically harmful, as parametric tests are robust to moderate deviations from normality, while reliance on normality tests can distort error rates and mislead researchers.
While prior studies have analyzed Skin Picking Disorder as a unitary condition, little research has been done examining clinical and neurocognitive characteristics of specific subtypes. The objective of this study is to analyze differences in impulsivity, emotional regulation, symptom severity, cognitive performance, and the presence of comorbid psychiatric conditions between focused and automatic subtypes of Skin Picking Disorder.
Methods
83 adults aged 18–65 with skin picking disorder were enrolled at the University of Chicago and separated into 4 skin picking subtype groups based on high or low levels of focused and automatic picking scores on the Milwaukee Inventory for the Dimension of Adult Skin Picking. The 4 subtype groups were separated using K-means clustering. Each group completed the same clinical and neurocognitive assessments. ANOVA or Chi-Squared tests were used to analyze differences in assessment outcomes.
Results
Higher focused picking scores were significantly associated with greater symptom severity and impairment. Differences in levels of automatic/focused picking were not associated with impulsivity, emotional/behavior regulations, or neurocognitive outcomes.
Conclusions
The findings suggest that focused skin pickers are likely to have more impairment due to their behavior compared to automatic or mixed pickers; however, overall, the groups did not differ in clinical or neurocognitive measures. Thus, it is unclear whether focused and automatic picking are particularly useful clinically in subtyping skin picking disorder.
