RESUMEN
Introduction: We report an epileptic patient who experienced hallucinatory visual experiences of autobiographical memories from her past. These visual experiences were confined to the lower left quadrant of her visual field.Methods: We carried out a single-case study that used brain-imaging, EEG and behavioural methods to study this patient.Results: We found that this patient had an incomplete left inferior homonymous quadrantanopia due to a lesion of right occipital cortex, and also that she showed neurological abnormalities in right temporal cortex, a region that is part of the brain's autobiographical-memory circuit.Conclusion: We attribute the occurrence of this patient's autobiographical-memory hallucinations to the combination of degraded visual input to right temporal cortex plus hyperexcitability of that region.

OBJECTIVE: The present study examined among orthopedic residents the relationship between the presence of depressive or anxious symptoms and the degree of perfectionism, perceived work-related distress, and involvement in the care of patient(s) who died. METHOD: A cross-sectional online survey based on self-reported measures was used to collect the data from October 2019 to April 2021. RESULTS: The sample consisted of 642 orthopedic residents (50.6% response rate; 70.9% male; average age 29.8 years old). A total of 12.5 and 18.4% reported depressive or anxious symptoms, respectively. On a scale of 0-100, the mean score of perceived work-related distress was 51.9. A third (33.6%) reported being involved in the care of patient(s) who had died. Higher levels of perceived work-related distress and higher scores on the indecision of action/perfectionism dimension were associated with depressive and anxious symptoms. Being involved in the care of patient(s) who had died was associated with having anxious symptoms (OR = 1.79; 95%CI = 1.18-2.72). CONCLUSIONS: These results highlight the need for the systematic monitoring of the mental health status of orthopedic residents in Mexico, particularly those who report a high level of work-related distress or perfectionism or who have recently experienced the death of a patient.
RESUMEN
BACKGROUND: The concept of environmental enrichment (EE) encompasses complex physical, social, cognitive, motor, and somatosensory stimuli to which individuals are differentially exposed. An indicator of EE comprising these elements would facilitate the study of the impact of EE in diverse clinical settings by allowing an easy and comparable measurement. This study aimed to create and test such an EE indicator based on the Florida Cognitive Activities Scale (FCAS), the Multidimensional Social Integration in Later Life Scale (SILLS), and the International Physical Activity Questionnaire (IPAQ). METHODS: Participants with major depression and control subjects were recruited in this cross-sectional comparative study. Depressive symptom severity was assessed with the Hamilton Depression Rating Scale (HAM-D). The EE indicator was used to evaluate cognitive, social, and physical activity. We divided the sample into three levels of cognitive and social activities to construct an EE indicator and compared the obtained scores between participants with major depression and control subjects. RESULTS: 40 patients suffering from major depression and 50 control subjects were included. Higher HAM-D scores were associated with lower EE levels. Cognitive and social items exhibited adequate reliability. Control subjects reported higher scores in all three activities evaluated, except for some items of physical activities. This indicator of EE clearly differentiated between participants with major depression from control subjects. CONCLUSIONS: FCAS, SILLS, and IPAQ used together are valid to evaluate EE. This EE indicator may be a useful tool during clinical practice. The cross-sectional design and the small sample size are limitations of the present study.

INTRODUCTION: A first manic episode after 50 years of age is uncommon. Late Onset Mania might be indicative of abnormalities in white matter, probably related to vascular, degenerative, or inflammatory processes. OBJECTIVE: To determine if patients with late onset mania have reduced white matter integrity according to Magnetic Resonance Diffusion Tensor Imaging (DTI) and structural MRI. METHODS: Twenty-two patients with late onset mania (>50 years old) and 22 age-paired healthy subjects were included in the study. Fractional anisotropy (FA) was used as a quantitative measure of white matter integrity. Fazekas scale was assessed also to measure white matter abnormalities in the FLAIR sequence. The Frontal Assessment Battery, COGNISTAT and Trail making test A and B were used as cognitive measurements. RESULTS: According to DTI, commissural connections (left corpus callosum), and limbic connections (right and left uncinate fasciculus) were different between the patients and the comparison group. Fractional anisotropy values in the left corpus callosum showed significant correlations with neuropsychological measures, and with the Fazekas scale score. According to Fazekas scale, a pathological score in the FLAIR sequence was significantly more frequent in the patients as compared to the comparison group. CONCLUSIONS: Patients with first episode mania in late life have relevant white matter abnormalities not explained by age, affecting interhemispheric and fronto-limbic networks probably related to executive functioning and emotional processing, at the level of the corpus callosum and the uncinate fasciculus. The etiology of this white matter loss of integrity in patients with late-onset mania is yet to be explored.

OBJECTIVE: The objective was to determine and compare demographic features, professional activities and adversities, physical health conditions, and self-care behaviors related to the most frequently self-reported mental health problems among psychiatrists and psychiatry trainees. METHODS: A cross-sectional, retrospective, comparative study was conducted on a total of 330 (48.2%) psychiatry trainees and 355 (51.8%) psychiatrists from Mexico through an online survey. Demographic features, professional activities and adversities, physical and mental health problems, self-care behaviors, and social support were examined. Comparative analyses and multiple logistic regression models were performed. RESULTS: Major depression, anxiety, and burnout were the most common mental health problems reported with a higher frequency of anxiety disorders in psychiatry trainees. Being a woman, having a physical health problem, and lack of restful sleep were the main risk factors in both groups. Consultation in the government sector and having patients with severe suicidal ideation affected more psychiatry trainees. Perceived discrimination and inadequate eating schedules were risk factors for mental health problems for psychiatrists. CONCLUSION: Psychiatry trainees constitute a vulnerable group for anxiety disorders. Particular attention should be paid to how students cope with the training experience to determine whether additional support is required. These professionals face major stressors leading to a high prevalence of depression, burnout, and anxiety. Encouraging psychiatrists to have better health habits is a step in the right direction, which must be accompanied by tangible organizational avenues to do so and creating a culture that truly promotes self-care.

BACKGROUND/AIMS: Orthotopic liver transplantation (OLT) is the recommended treatment for patients at early stages of hepatocarcinoma (HCC) with portal hypertension and/or increased bilirubinemia, but without vascular-associated diseases. Tumor recurrence, which is the main drawback for the survival of patients submitted to OLT for HCC, has been related to tumor-related variables and the immunosuppressive therapies. We have previously shown that Tacrolimus (FK506) exerts a more potent pro-apoptotic and anti-proliferative effects than the mammalian target of rapamycin (mTOR) inhibitors (Sirolimus and Everolimus) in liver cancer cells. This study identified the role of the immunosuppressant partners such as FK506-binding proteins (FKBPs) in the induction of cell death and arrest of cell proliferation by immunosuppressants in two representative liver cancer cells. METHODS: The regulation of endoplasmic reticulum (ER) stress, apoptosis/autophagy, cell proliferation, and FKBPs expression was determined in Tacrolimus-, Sirolimus- and Everolimus-treated primary human hepatocytes, and hepatoma HepG2 and Huh7 cell lines. The functional repercussion of FKBPs on cell death and proliferation was also addressed using the siRNA technology. The assessed antitumoral properties of the immunosuppressants were associated to microRNAs (miRNAs) pattern. RESULTS: The enhanced pro-apoptotic and anti-proliferative properties of Tacrolimus versus mTOR inhibitors were associated with increased protein kinase RNA-like endoplasmic reticulum kinase (PERK)-related ER stress, Ser15P-p53/p53 ratio and p21 protein expression that may counterbalance the risk of proliferative upregulation caused by enhanced Thr172P-Cdk4/Cdk4 activation in liver cancer cells. The inhibition of the mTOR pathway by Sirolimus and Everolimus was related to an induction of autophagy; and at a high dose, these drugs impaired translation likely at a very early step of the elongation phase. Tacrolimus and mTOR inhibitors increased the protein expression of FKBP12 and FKBP51 that appeared to play pro-survival role. Interestingly, the administration of immunosuppressants yields a specific pattern of miRNAs. Tacrolimus and mTOR inhibitors decreased miR-92a-1-5p, miR-197-3p, miR-483-3p and miR-720, and increased miR-22-3p, miR-376a-3p, miR-663b, miR-886-5p, miR-1300 and miR-1303 expressions in HepG2 cells. CONCLUSION: The more potent pro-apoptotic and anti-proliferative properties of Tacrolimus versus mTOR inhibitors were associated with an increased activation of PERK and p53 signaling, and p21 protein expression. FKBP12 and FKBP51 appeared to be the most relevant partners of Tacrolimus and mTOR inhibitors exerting a pro-survival effect in HepG2 cells. The observed effects of immunosuppressants were related to a specific miRNA signature in liver cancer cells.

BACKGROUND: The method used to collect, store, and analyze data can affect the quality of data obtained. Many studies have shown the advantages of electronic systems over paper. Numerous tools are available for this purpose; however, they tend to be implemented only in high-budget protocols as they tend to be expensive. INTRODUCTION: We report the experience of the Affective Disorders' Clinic of the National Institute of Psychiatry in Mexico City using Adobe Acrobat® Forms combined with Dropbox® as storage and distribution method for clinical protocols. MATERIALS AND METHODS: Adobe Acrobat 9 Pro® was used to create personalized forms to capture data for seven different clinical purposes. Dropbox was used to share the distributed forms with fellow researchers. Completed forms were stored in Dropbox and the main researcher kept the data collection file, from where the forms were gathered for analysis. RESULTS: Sixteen forms created for different clinical purposes had an average of 1.2% missing fields. DISCUSSION: The main drawbacks relate to remote filling and the time spent in fine-tuning complex forms. The main advantages relate to the simplicity of the implementation of the method and the fact that no software other than the one available at the Institute is required. CONCLUSIONS: Compared with other types of electronic data collection systems, the combination of these tools achieves similar goals and is low cost, requiring minimal knowledge of informatics.

Purpose: Despite the high prevalence of anxiety disorders in BD and its known impact on cognitive performance, the presence and severity of anxious symptoms is not systematically evaluated in studies on cognition in BD. Our aim was to determine if attention and/or inhibition of cognitive interference in euthymic patients with type I Bipolar Disorder (BD-I) is affected by symptoms of anxiety. Patients and Methods: Eighty-seven euthymic BD-I patients were included. Patients with comorbidities other than Generalized Anxiety Disorder (GAD) or Panic Disorder (PD) were excluded. State anxiety was measured with the Brief Inventory of Anxious Responses and Situations (ISRA-B). Subjective cognitive performance was evaluated with the COBRA scale, attention with the Digit-Span Forward task and inhibition of cognitive interference was assessed with the StroopTest interference score. Multiple linear regression models were used to test if anxious symptoms were associated with attention or inhibition of cognitive interference, considering other known contributors for cognitive impairment. Results: Attention was unaffected by anxiety symptoms, but the overall regression for inhibition of cognitive interference was significant: years of schooling (ß=1.12, p = 0.001), cognitive complaints (ß=0.44, p = 0.008), and anxiety (ß=-0.21, p = 0.017) explained 15% of the interference score of the Stroop test (R2 = 0.15). Conclusion: Beyond residual affective symptoms, anxious symptoms seem to affect inhibition of cognitive interference. We recommend routine testing of anxiety when considering cognitive evaluations, especially when screening for cognitive deficits.
RESUMEN
Cognitive deficits play an important role in Bipolar Disorder (BPD). The Cognitive Problems and Strategies Assessment (CPSA) is a measure that evaluates the patient's perception of cognitive difficulties, and the spontaneous use of compensatory strategies and could thus have potential utility for clinical practice in patients with BPD. Our aim was to determine the validity and reliability of the Cognitive Problems and Strategies Assessment (CPSA) in Bipolar Disorder (BPD). Ninety-three BPD outpatients and 90 controls completed the Assessment of Problems with Thinking and Memory (APTM) questionnaire and the Assessment of Memory and Thinking Strategies (AMTS) questionnaire which constitute the CPSA, the Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA), as a measure of convergent validity, and general sociodemographic data. Cronbach's alpha coefficient, Spearman's correlation coefficient and independent sample t tests were used for Internal consistency, Convergent validity and Discriminant validity. The APTM had a Cronbach's alpha coefficient of 0.93 and the AMTS 0.90. The COBRA score and the APTM were significantly correlated. BPD patients exhibited higher scores on the APTM and lower scores on the AMTS than controls. The present instrument enriches the clinician's repertoire for rapid and inexpensive cognitive evaluation in BPD.
RESUMEN
Introduction: Pediatricians in training are a population at risk for anxiety and depression: they face long working hours, they are confronted with the suffering and death of a vulnerable population and may have personal characteristics that put them in danger. Nonetheless, few studies have looked at their prevalence and associated factors. We aimed to compare demographic, professional activities, adversities and perfectionism personality features between a group of pediatricians in training with depression and/or anxiety and a group of pediatricians in training without depression nor anxiety and, to identify the variables that increase the probabilities of depression and/or anxiety in pediatricians in training. Methods: Pediatric residents who voluntarily answered an online survey distributed via personal and institutional social media channels from October 2019 to April 2021, as part of a cross-sectional study with medical specialists and residents from Mexico were included. Demographic information, professional activities and adversities, perfectionism personality features (Multidimensional Perfectionism Scale), depression and anxiety (ICD-11 PHC) were evaluated. For comparison purposes Chi-square tests (χ2) and independent sample t-tests were used. A logistic regression analysis was used to identify those variables that increase the probabilities of depression and/or anxiety. Results: 934 pediatric residents answered the survey. 11.6% reported having depression and 20% anxiety. Being single, a history of anxious or depressive episodes, being the resident in charge of a patient who died, aggressions from colleagues and a high concern for errors were associated with current depression and/or anxiety. Discussion: Screening for depressive and anxious symptoms should be routinely performed from entry to the residency to favor early intervention. A shift from promoting perfectionism to a more compassionate training could serve a population facing so many adversities.
RESUMEN
BACKGROUND: Heat-related illness (HRI) is an important cause of non-fatal illness and death in farmworkers. We sought to identify potential barriers to HRI prevention and treatment in Latino farmworkers. METHODS: We conducted three semi-structured focus group discussions with 35 Latino farmworkers in the Central Washington, USA area using participatory rural appraisal techniques. Interviews were audio taped and transcribed in Spanish. Three researchers reviewed and coded transcripts and field notes, and investigator triangulation was used to identify relevant themes and quotes. RESULTS: Although the majority of participants in our study reported never receiving formal HRI training, most participants were aware that extreme heat can cause illness and were able to accurately describe HRI symptoms, risk factors, and certain prevention strategies. Four main observations regarding farmworkers' HRI-relevant beliefs and attitudes were identified: 1) farmworkers subscribe to varying degrees to the belief that cooling treatments should be avoided after heat exposure, with some believing that such treatments should be avoided after heat exposure, and others encouraging the use of such treatments; 2) the desire to lose weight may be reflected in behaviors that promote increased sweating; 3) highly caffeinated energy drinks are preferred to increase work efficiency and maintain alertness; and 4) the location of drinking water at work (e.g. next to restrooms) and whether water is clean, but not necessarily chemically-treated, are important considerations in deciding whether to drink the water provided at worksites. CONCLUSIONS: We identified potential barriers to HRI prevention and treatment related to hydration, certain HRI treatments, clothing use, and the desire to lose weight among Latino farmworkers. Strategies to address potential barriers to HRI prevention and treatment in this population may include engineering, administrative, and health education and health promotion strategies at individual, workplace, community, and societal levels. Although farmworkers in our study were able to describe HRI risk factors, reported practices were not necessarily consistent with reported knowledge. Further study of potential knowledge-behavior gaps may uncover opportunities for additional HRI prevention strategies. Farmworkers and employers should be included in the development and evaluation of interventions to prevent HRI.

BACKGROUND: Pesticides used in agriculture can be taken into worker homes and pose a potential risk for children and other family members. This study focused on identification of potential intervention points at the workplace. METHODS: Workers (N = 46) recruited from two tree fruit orchards in Washington State were administered a 63-item pesticide safety questionnaire. Dust was collected from commuter vehicles and worker homes and analyzed for four organophosphorus (OP) pesticides (azinphosmethyl, phosmet, chlorpyrifos, malathion). RESULTS: Geometric mean azinphosmethyl concentrations in dust for three worker groups (16 pesticide handlers, 15 green fruit thinners, 15 organic orchard workers) ranged from 0.027-1.5 µg/g, with levels in vehicle dust higher than in house dust, and levels in house dust from handlers' homes higher than levels from tree fruit thinners' homes. Vehicle and house dust concentrations of azinphosmethyl were highly associated (R(2) = 0.44, P < 0.001). Significant differences were found across worker groups for availability of laundry facilities, work boot storage, frequency of hand washing, commuter vehicle use, parking location, and safety training. CONCLUSIONS: These findings support a focus on intervention activities to reduce take home pesticide exposure closer to the source of contamination; specifically, the workplace and vehicles used to travel to the workplace.

A large number of patients with celiac disease (CD) remain undiagnosed because they do not fulfill the criteria for entry into the conventional diagnostic workflow. This study evaluated the clinical utility of anti-tissue transglutaminase IgA antibody lateral flow immunoassays (anti-tTG-IgA LFIA) in the undiagnosed-CD-based pediatric population and the impact of a gluten-free diet (GFD) on screening-detected CD. A total of 576 volunteers were tested for anti-tTG-IgA. Gluten consumption habits, CD related symptoms, and risk factors for CD development were evaluated. Volunteers testing positive for anti-tTG-IgA were referred to the conventional CD diagnostic workflow, and the impact of the GFD on health-related quality of life (HR-QoL) was measured. Among them, 13 had a positive anti-tTG-IgA LFIA test result: 11 had confirmed CD (1.91%), one refused confirmatory tests, and another is undergoing diagnosis. Regarding the CD prevalence, no significant differences were observed among risk (1.89%) and symptomatic (2.65%) groups and the entire tested population (1.55%). Rapid anti-tTG-IgA LFIAs could be of clinical utility in primary care for the early identification of children with CD unidentified by the conventional diagnostic workflow. It could potentially reduce the costs of undiagnosed CD, avoiding unnecessary referrals to gastroenterologists, reducing diagnosis delays and long-term problems, and improving patients' HR-QoL.

BACKGROUND: Physicians in training face a variety of stressors throughout their professional development and according to their gender. Among them, surgical trainees appear to be especially at risk for mental health problems. OBJECTIVE: The aim of the present study was to compare demographic features, professional activities and adversities, depression, anxiety, and distress among men and women trainees of surgical and nonsurgical medical specialties. DESIGN AND PARTICIPANTS: A cross-sectional, retrospective, comparative study was conducted on a total of 12,424 trainees (68.7% nonsurgical and 31.3% surgical) from Mexico through an online survey. Demographic features, variables related to professional activities and adversities, depression, anxiety, and distress were evaluated through self-administered measures. Comparative analyses using the Cochran-Mantel-Haenszel test for categorical variables and multivariate analysis of variance including medical residency program and gender as fixed factors to test their interaction effect for continuous variables were used. RESULTS: An important interaction between medical specialty and gender was found. Women trainees from surgical specialties report more frequent psychological and physical aggressions. Women from both specialties had higher distress, significant anxiety, and depression than men. Men from surgical specialties worked more hours per day. CONCLUSIONS: Gender differences are evident in trainees for medical specialties, with a larger impact in surgical fields. Mistreatment of students is a pervasive behavior that affects society as a whole, and actions to improve learning and working environments in all medical specialties, but mostly in surgical fields, are urgently needed.

BACKGROUND: Electroconvulsive therapy (ECT) is an effective treatment for depression, mania, and refractory schizophrenia. Its tolerability profile is established for acute treatment, but less is known regarding the effects of longer treatment courses, particularly on cognitive performance. OBJECTIVES: To assess the effect of the long-term ECT on cognition. METHODS: We searched CINAHL, EMBASE, PsychInfo and Pubmed, for the period between January 1, 2010, and June 30, 2022, in English or French, for randomized controlled trials, prospective or retrospective studies of ECT continued for at least 2 months for the treatment of mood or schizophrenic disorders and which measured cognition before and at the end of treatment. Non-peer reviewed records were excluded. The Cochrane Risk of Bias tool was used to assess study quality. Classical meta-analyses, with heterogeneity statistics (tau2, I2) were complemented with three level-meta-analysis and Bayesian Meta-analyses. RESULTS: Nine studies were included in the narrative and quantitative review. Controlled comparison at 6 months (k = 6, n = 334) and at 12 months (k = 3, n = 56), within-subject comparisons at 6 (k = 6, n = 218) and 12 months (k = 4, n = 147) showed no detrimental effect of maintenance or continuation ECT on cognition, with little to no heterogeneity. Bayesian analysis further confirmed that data better supported the no effects hypothesis. LIMITATIONS: Insufficient data resulted in imprecision in estimates. CONCLUSIONS: Continuation and maintenance ECT do not appear detrimental for cognitive performance. However, the low number of studies limit the interpretation of the results.

Background: Psychiatrists are at high risk of developing burnout and mental health problems mainly due to their emotionally demanding jobs, difficult working conditions, long working hours, and poor work-life balance. As leisure activities are associated with better physical and mental health, engaging in these activities has been recommended as a measure to improve the wellbeing of healthcare workers. However, it is unclear the extent of which psychiatrists and trainees are involved in leisure activities, what type of activities they prefer, or how these impact their self-perceived health, stress, confidence in stress management, and satisfaction with their social support. Objective: The aim of this study was to identify differences in self-perceived health, perceived stress, confidence in stress management, and satisfaction with social support, between psychiatrists and trainees who engage in different leisure activities, compared with those who do not. Methods: This was a cross-sectional study, including Mexican psychiatrists (n = 355) and trainees (n = 330) who agreed to participate through an online survey. Results: 73.1% of participants engaged in some leisure activity, being solitary-passive activities the most reported. Those who have a leisure activity reported lower stress, greater confidence in stress management, and more satisfaction with their social support. Passive-solitary activities were associated with less perceived stress and better confidence in stress management, while active-solitary and social activities were associated with better satisfaction with social support. Conclusion: Psychiatrists' and trainees' wellbeing benefits from engagement in leisure activities, which should be part of their daily schedules to reduce stress, and potentially improve their mental health.
RESUMEN
INTRODUCTION: The present study aims to examine sex differences in demographic variables, professional activities and adversities, self-reported mental health problems, and perceived discrimination in a sample of family doctors and family medicine residents in Mexico. METHODS: From a larger sample of medical specialists, an analytic, cross-sectional study was conducted with 566 participants, including 317 (56%) family medicine residents and 249 (44%) family doctors in Mexico through an online survey. Demographic features, professional activities and adversities, mental health, and perceived discrimination were examined. Descriptive and comparative analyses were performed. Cramer's V for chi-square tests and Hedge's g for t test were conducted to determine effect sizes. RESULTS: Both sexes displayed similar percentages of professional adversities (such as attending patients with suicidal behavior or who died not by suicide under their care), and a higher number of women reported seeking specialized support to cope with these deaths (Fisher = 0.04). Men perceived greater discrimination (P = .01), worked more hours per day (P < .001) and were more verbally assaulted (P = .04), whereas women reported mental health problems more frequently (P < .001) particularly depression, anxiety, burnout and sleeping problems. Women also reported worse health status (P < .001) when compared with men. CONCLUSION: Family medicine specialists constitute a vulnerable group for mental health problems and perceived discrimination. Particular attention should be paid to how men and women cope with professional adversities to determine whether additional support is required. Interventions should encourage self-care and promote the well-being of health personnel.

INTRODUCTION: Functioning in Bipolar Disorder (BD) is affected in a substantial proportion of patients. The impact of demographic, clinical, cognitive, and genetic factors on functioning has been shown individually; however, as a complex phenomenon, a global approach to identify the most relevant as well as possible interactions is needed. METHODS: 102 patients with type I BD in euthymia were invited for evaluation of demographic, clinical, and cognitive characteristics as well as genotype for Val66Met polymorphism of BDNF gene to determine those associated with poor functioning according to the FAST scale cut-off score. Clinical evaluation included assessment of residual affective symptoms and anxiety. Cognitive evaluation included the COBRA scale, verbal memory, and executive functions testing. RESULTS: Residual depressive symptoms, anxiety, cognitive complaints and being a Met carrier were more frequent in the poor functioning group and were entered in a logistic regression model. Being a Met carrier (OR=4.46, CI=1.19-16.67) and cognitive complaints (OR=1.29, CI= 1.13-1.46) were the most important predictors of poor functioning in type I BD. LIMITATIONS: Cross-sectional study, with select population limiting generalizability of findings. CONCLUSIONS: A better understanding of underlying factors affecting cognition, including the possible involvement of BDNF Val66Met polymorphism, its systematic evaluation and a continued search for targeted treatment, along with recognition and attention of residual affective and anxious symptoms might improve psychosocial outcomes such as functioning in this population.

Hepatocellular carcinoma (HCC) is the sixth most common neoplasia and the fourth most common cause of cancer-related mortality worldwide. Sorafenib is the first-line molecular therapy for patients in an advanced stage of HCC. However, the recommended clinical dose of Sorafenib is associated with several complications, which derive from its lack of cell specificity and its very low water solubility. To circumvent these drawbacks, in the present study we developed two sugar-coated polydiacetylene-based nanomicelles-Sorafenib carriers targeting mannose and asialoglycoprotein receptors (MR and ASGPR, respectively). The strategies allowed the inducement of apoptosis and reduction of cell proliferation at a nanomolar, instead of micromolar, range in liver cancer cells. The study showed that, contrary to literature data, Sorafenib included into the pMicMan (Man = mannose) vector (targeting MR) is more efficient than pMicGal (Gal = galactose) (targeting ASGPR). Indeed, pMicMan increased the endosomal incorporation with an increased intracellular Sorafenib concentration that induced apoptosis and reduced cell proliferation at a low concentration range (10-20 nM).

BACKGROUND: Much remains unknown about the transmission of the SARS-CoV-2 virus. Pregnant women are considered part of the risk population, and vertical transmission of other coronaviruses has been suggested; however, this type of transmission in SARS-CoV-2 is believed to be unlikely. CASE REPORT: A newborn delivered in term via cesarean section to an asymptomatic but COVID-19-positive 35-year-old woman started with respiratory distress in the first 30 min of life. A chest radiograph revealed pneumothorax and ground glass opacities. Ventilatory support with continuous positive airway pressure was needed. Given the respiratory failure and the positive test from the mother, the patient was sampled for SARS-CoV-2 (RT-PCR) at minute 30 of life, with a positive result reported at 36 h of life. No complications had been present during pregnancy, and cardiac screening and blood cultures revealed no other etiologies. CONCLUSION: Vertical transmission was highly likely in this case. Clinicians should be alert and report similar cases.
