Review
Citicoline is the generic name of CDP-choline, a natural metabolite presents in all living cells. Used in medicine as a drug since the 1980-s, citicoline was recently pronounced a food ingredient. When ingested, citicoline breaks down to cytidine and choline, which become incorporated into their respective normal metabolic pathways. Choline is a precursor of acetylcholine and phospholipids; these is a neurotransmitter pivotal for learning and memory and important constituents of neuronal membranes and myelin sheaths, respectively. Cytidine in humans is readily converted to uridine, which exerts a positive effect on synaptic function and supports the formation of synaptic membranes. Choline deficiency has been found to be correlated with memory dysfunction. Magnetic resonance spectroscopy studies showed that citicoline intake improves brain uptake of choline in older persons, suggestive of that it shall help in reversing early age-related cognitive changes. In randomized, placebo-controlled trials of cognitively normal middle-aged and elderly persons, positive effects of citicoline on memory efficacy were found. Similar effects of citicoline on memory indices were also found in patients suffering from mild cognitive impairment and some other neurological diseases. Altogether, the aforementioned data provide complex and unambiguous evidence supporting the claim that oral citicoline intake positively influences memory function in humans who encounter age-related memory impairment also in the absence of any detectable neurological or psychiatric disease.

Randomized Controlled Trial Comparative Study
A low FODMAP diet plus traditional dietary advice versus a low-carbohydrate diet versus pharmacological treatment in irritable bowel syndrome (CARIBS): a single-centre, single-blind, randomised controlled trial.
BACKGROUND
Dietary advice and medical treatments are recommended to patients with irritable bowel syndrome (IBS). Studies have not yet compared the efficacy of dietary treatment with pharmacological treatment targeting the predominant IBS symptom. We therefore aimed to compare the effects of two restrictive dietary treatment options versus optimised medical treatment in people with IBS.
METHODS
This single-centre, single-blind, randomised controlled trial was conducted in a specialised outpatient clinic at the Sahlgrenska University Hospital, Gothenburg, Sweden. Participants (aged ≥18 years) with moderate-to-severe IBS (Rome IV; IBS Severity Scoring System [IBS-SSS] ≥175) and no other serious diseases or food allergies were randomly assigned (1:1:1) by web-based randomisation to receive a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) plus traditional IBS dietary advice recommended by the UK National Institute for Health and Care Excellence (hereafter the LFTD diet), a fibre-optimised diet low in total carbohydrates and high in protein and fat (hereafter the low-carbohydrate diet), or optimised medical treatment based on predominant IBS symptom. Participants were masked to the names of the diets, but the pharmacological treatment was open-label. The intervention lasted 4 weeks, after which time participants in the dietary interventions were unmasked to their diets and encouraged to continue during 6 months' follow-up, participants in the LFTD group were instructed on how to reintroduce FODMAPs, and participants receiving pharmacological treatment were offered diet counselling and to continue with their medication. The primary endpoint was the proportion of participants who responded to the 4-week intervention, defined as a reduction of 50 or more in IBS-SSS relative to baseline, and was analysed per modified intention-to-treat (ie, all participants who started the intervention). Safety was analysed in the modified intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02970591, and is complete.
FINDINGS
Between Jan 24, 2017, and Sept 2, 2021, 1104 participants were assessed for eligibility and 304 were randomly assigned. Ten participants did not receive their intervention after randomisation and thus 294 participants were included in the modified intention-to-treat population (96 assigned to the LFTD diet, 97 to the low-carbohydrate diet, and 101 to optimised medical treatment). 241 (82%) of 294 participants were women and 53 (18%) were men and the mean age was 38 (SD 13). After 4 weeks, 73 (76%) of 96 participants in the LFTD diet group, 69 (71%) of 97 participants in the low-carbohydrate diet group, and 59 (58%) of 101 participants in the optimised medical treatment group had a reduction of 50 or more in IBS-SSS compared with baseline, with a significant difference between the groups (p=0·023). 91 (95%) of 96 participants completed 4 weeks in the LFTD group, 92 (95%) of 97 completed 4 weeks in the low-carbohydrate group, and 91 (90%) of 101 completed 4 weeks in the optimised medical treatment group. Two individuals in each of the intervention groups stated that adverse events were the reason for discontinuing the 4-week intervention. Five (5%) of 91 participants in the optimised medical treatment group stopped treatment prematurely due to side-effects. No serious adverse events or treatment-related deaths occurred.
INTERPRETATION
Two 4-week dietary interventions and optimised medical treatment reduced the severity of IBS symptoms, with a larger effect size in the diet groups. Dietary interventions might be considered as an initial treatment for patients with IBS. Research is needed to enable personalised treatment strategies.

Since 2010, the number of life science doctoral graduates opting into academic postdoctoral employment has steadily declined. In recent years, this decline has made routine headlines in academic news cycles, and faculty members, universities, and funding bodies alike have begun to take notice. In November 2022, the National Institutes of Health (NIH) convened a special interest group to address the problems in postdoctoral recruitment and retention. In response, the American Physiological Society Science Policy Committee highlighted several key issues in postdoctoral training and working conditions and offered the NIH solutions to consider. There are known issues that affect postdoctoral recruitment and retention efforts: low wages relative to other employment sectors, a heavy workload, and poor job prospects to name a few. Unfortunately, these concerns are frequently dismissed as "the price of doing business in academia," and postdoctoral scholars are promised that if they overcome the trials and tribulations of this training period, the reward at the end, a career with academic freedom to pursue your own interests, justifies the means. However, academic freedom cannot and should not be used as the band-aid in a system where most of us will never actually experience academic freedom. Instead, we should systematically embrace solutions that improve the personal and professional health of early career researchers in all levels of training and independence if the goal is to truly shore up the academic workforce.

BACKGROUND
The current study aims to examine association of dietary live microbes and nondietary prebiotic/probiotic intake with cognitive function among older U.S. adults, examining heterogeneity across demographic characteristics and diseases.
METHODS
Participants from the National Health and Nutrition Examination Survey 2011-2014 cycles were selected and administered 3 cognitive function tests: the Consortium to Establish a Registry for Alzheimer's Disease Word Learning subtest (CERAD W-L, including immediate [CERAD-IRT] and delayed [CERAD-DRT] memory), the Animal Fluency Test (AFT), and the Digit Symbol Substitution Test (DSST). Test-specific and global cognition z-score was created. Based on their estimated dietary live microbes intake, participants were categorized into three groups: low, medium, and high. Text mining was employed to identify nondietary prebiotic/probiotic usage by examining the names and ingredients of dietary supplements or drugs.
RESULTS
Participants in the medium (including AFT) and high (including global cognition, AFT, DSST, and CERAD-IRT) dietary live microbes intake group had significantly higher z-score of cognitive function compared to those in the low intake group. Among participants with cardiovascular disease history, nondietary prebiotic intake was associated with higher z-score in global cognition and CERAD-DRT compared to those who did not consume prebiotic. Additionally, probiotic intake was linked to higher z-score in global cognition, AFT, and DSST, particularly in participants with diabetes mellitus or hypertension.
CONCLUSIONS
Our study suggests that the intake of dietary live microbes and nondietary probiotic/prebiotic was associated with better cognitive function in older adults, particularly in specific disease states.

Takotsubo syndrome (TTS) can be described as an acute, transiently occurring form of heart failure. It typically causes systolic dysfunction of the left ventricle (LV). Perhaps what is of most significance is the reversible nature of TTS, with many patients achieving recovery within a few weeks to months. TTS can be referred to by other names, attributed to its various precipitants, as well as the structural manifestations of the syndrome. Physical and emotional stressors have been identified as the most common of causes, hence the terms 'stress cardiomyopathy' and 'broken heart syndrome'. Precipitants can range from psychological, and hormonal, to molecular mechanisms. The symptoms of TTS can coalesce with other conditions and hence give rise to many differential diagnoses. Most patients present with dyspnoea and chest pain. The latter also presents in acute coronary syndrome (ACS); thus, ACS is a common differential diagnosis for TTS. The coronavirus disease 2019 (COVID-19) pandemic saw a drastic increase in mental health concerns which have persisted beyond this period. Further studies into personality disorders and their potential predisposition to COVID-19 and thus TTS would advance our understanding of the neuropsychiatric triggers of TTS. There is also a need for a single sensitive and specific diagnostic test for TTS as its diagnosis relies on the culmination of clinical presentation, echocardiography, cardiac catheterization, and cardiovascular magnetic resonance imaging (CMR).

The concept of personhood has been central to bioethics debates about abortion, the treatment of patients in a vegetative or minimally conscious states, as well as patients with advanced dementia. More recently, the concept has been employed to think about new questions related to human-brain organoids, artificial intelligence, uploaded minds, human-animal chimeras, and human embryos, to name a few. A common move has been to ask what these entities have in common with persons (in the normative sense), and then draw conclusions about what we do (or do not) owe them. This paper argues that at best the concept of "personhood" is unhelpful to much of bioethics today and at worst it is harmful and pernicious. I suggest that we (bioethicists) stop using the concept of personhood and instead ask normative questions more directly (e.g., how ought we to treat this being and why?) and use other philosophical concepts (e.g., interests, sentience, recognition respect) to help us answer them. It is time for bioethics to end talk about personhood.

Family physicians commonly find themselves in difficult patient encounters that can result in dissatisfaction for the patient and physician. Successful navigation of these encounters includes recognizing common physician factors, such as systemic pressures, interpersonal communication, and situational issues. The practice of labeling patient types can lead to disparities in care and patient harm and should be avoided. When physicians recognize that they are in a difficult patient encounter, simple mindfulness approaches, such as the Name It to Tame It and CALMER approaches, can improve outcomes. CALMER approaches help physicians acknowledge which situations they can control, alter their thoughts about the situation, and tolerate uncertainty. Physicians working with patients to create a therapeutic bond can focus the encounter to understand the situation that the patient is experiencing and work to recognize and acknowledge strong emotions that are nonproductive. Negotiating an agenda can help manage expectations of what can reasonably be done during each visit. Supporting patients by validating their symptoms and helping them embrace uncertainty can enable them to take control of their diagnosis and focus on managing chronic conditions rather than curing them. Motivational interviewing is a useful tool to help patients take ownership of their illnesses and therapeutic goals. Self-care through reflection groups or personal coaching or counseling can help physicians feel supported and avoid burnout.

Acute disturbance of consciousness in a child is a potentially life-threatening condition. There are a variety of possible causes - traumatic, infectious, toxic, metabolic/endocrine, cardio-circulatory - to name a few. The history often provides important clues to narrow down the differential diagnoses. The recognition of reversible causes and a structured diagnostic process are life-saving in an emergency.
