Effects of exercise programs on cardiorespiratory fitness and arterial stiffness on postmenopausal women: A systematic review study

BACKGROUND

Arterial stiffness is an important marker of cardiovascular disease, with a considerable increase in menopause. The impact of exercise, as a preventive measure, on controlling the progression of cardiovascular disease and arterial dysfunction in middle age remains under investigation.

OBJECTIVE

This systematic review aims to present the results of studies that examined the effects of different exercise programs (isolated, aerobic, and resistance or combined) on arterial stiffness and cardiorespiratory fitness in postmenopausal women.

METHODS

Based on PRISMA guidelines, B-On, BioMed, EBSCOhost, MEDLINE, ScienceOpen, PubMed, Science Direct, Scopus, Web of Science, Cochrane library and LILACS databases were searched using specific keywords.

RESULTS

A final total of 13 manuscripts were included in the qualitative synthesis, involving 700 participants. Four studies used only cardiorespiratory exercise, three only resistance, taekwondo class or flexibility exercise, and six combined exercise programs. Most interventions ranged from 3 to 5 days per week. Carotid-femoral pulse wave velocity showed improvements between 0.22 m/s and 1.56 m/s. In addition, one study showed an improvement of 4.4 ml/kg/min in maximal oxygen consumption. In 7 studies, participation in exercise programs improved arterial stiffness.

CONCLUSIONS

Combined exercise (aerobic and resistance exercise) and aerobic exercise alone (swimming) improve cardiorespiratory fitness and arterial stiffness in postmenopausal women, particularly pulse wave velocity. The combined exercise program is the most effective, promoting improvements of up to -2.6 m/s in pulse wave velocity in this climacteric phase.

Tactical Knowledge by Decision Making and Motor Efficiency of Young Football Players in Different Playing Positions during a Three-a-Side Small-Sided Game

The aim of this study was to compare the tactical knowledge of young football players in different playing positions during a three-a-side small-sided game (SSG). Observational data was collected from 71 players (M = 12.16; SD = 1.55 years): 11 goalkeepers, 22 defenders, 15 midfielders, and 23 forwards. In total, 4 min of three-a-side SSGs (GR + 3 vs. 3 + GR) were recorded to assess tactical performance using a digital camera (GoPro Hero 6^® version 02.01). The SSGs were performed on a field with a constant area (36 × 27 m). Video analyses were performed using LongoMatch^® version 1.5.9 to record football performance; we then assessed tactical performance by using the Football Tactical Assessment System (Fut-Sat). This instrument evaluates the average of well-defined action indexes for each game in decision making principle and motor skills, specifically: (i) Decision Making Index (DMI); (ii) Motor Effectiveness Index (MEI); (iii) Effectiveness Index (I). The indexes were calculated by the ratio between the correct actions and the total. The Kruskal-Wallis test was used to evaluate differences between playing positions. The results showed that tactical performance by principles seems to be significantly different according to playing position. Differences were found between defenders and forwards (H = -11.92; p = 0.03) and defenders and midfielders (H = -16.13; p = 0.01) in contention principle. In conclusion, tactical knowledge of training based on the principles of the game can help coaches and players better understand and predict each player's actions during the game.

Contextuality and context-sensitivity in probabilistic models of cognition

The context-sensitivity of cognition has been demonstrated across a wide range of cognitive functions such as perception, memory, judgement and decision making. A related term, 'contextuality', has appeared from the field of quantum cognition, with mounting empirical evidence demonstrating that cognitive phenomena are sometimes contextual. Contextuality is a subtle notion that influences how we must view the properties of the cognitive phenomenon being studied. This article addresses the questions: What does it mean for a cognitive phenomenon to be contextual? What are the implications of contextuality for probabilistic models of cognition? How does contextuality differ from context-sensitivity? Starting from George Boole's "conditions of possible experience", we argue that a probabilistic model of a cognitive phenomenon is necessarily subject to an assumption of realism. By this we mean that the phenomenon being studied is assumed to have cognitive properties with a definite value independent of observation. In contrast, quantum cognition holds that a cognitive property maybe indeterminate, i.e., its properties do not have well established values prior to observation. We argue that indeterminacy is sufficient for incompatibility between cognitive properties. In turn, incompatibility is necessary for their contextuality. The significance of this argument for cognitive psychology is the following:if a cognitive phenomenon is found to be contextual, then there is reason to believe it may be indeterminate. We illustrate by means of two crowdsourced experiments how context-sensitivity and contextuality of cognitive properties in the form of facial trait judgements can be characterized from empirical data. Finally, we conceptually and formally contrast contextuality with context-sensitivity. We propose that both involve a form of context dependence, with causality being the differentiating factor: the context dependence in context-sensitivity has a causal basis, whereas the context dependence in contextuality is acausal. The resulting implications for probabilistic models of cognition are discussed.

Anti-NMDA Receptor Encephalitis or Psychiatric disorder?

Introduction

Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis commonly begins with a prodromal phase characterized by flu-like symptoms, subsequently the patients experience a rapid deterioration with psychiatric symptoms that may include anxiety, irritability, insomnia, paranoia, aggression, auditory or visual hallucinations, sexual disinhibition, mania, cognitive disorder, and psychosis; seizures; motor and autonomic dysfunction. The triggers of the disorder comprise viral infections, tumors, and other unknown factors. Taking in count the prominence of psychiatric symptoms, it is relevant to rise the question whether patients with anti-NMDA receptor encephalitis are being misdiagnosed with psychiatric disorders.

Objectives

Non-systematic literature review of the relationship between anti-NMDA receptor encephalitis and psychiatric disorders.

Methods

From the review performed, 2 studies stand out: In one study, 459 serum samples for NMDA receptor antibodies were evaluated. The analysis compared samples from patients diagnosed with schizophrenia, major depressive disorder, and borderline personality disorder with nonpsychiatric controls. In another study, serum was obtained prospectively from a cohort (n = 46) of patients at first presentation of psychosis and NMDA receptor antibodies were measured.

Results

In the first study, the authors found that 9.9%, 2.8%, and 0% of patients with schizophrenia, major depressive disorder, and borderline personality disorder, respectively, were antibody positive. In the second study, it was found that 7% of the patients were serum NMDA receptor antibody positive.

Conclusions

It is unclear yet if patients with primary psychotic disorders have higher rates of pathogenic NMDA receptor antibodies. More evidence is needed to study this relationship.

Disclosure

No significant relationships.

Semiquantitative analysis of interim 18F-FDG PET is superior in predicting outcome in Hodgkin lymphoma patients compared to visual analysis

PURPOSE

To investigate the prognostic value of interim PET (PETi) in adult HL patients, comparing visual with semiquantitative analysis.

MATERIAL AND METHODS

Retrospective analysis of Hodgkin's lymphoma (HL) patients diagnosed between 2012 and 2016 in the Onco-hematology Department of Instituto Português de Oncologia - Porto (median follow-up: 46.5 months [2.6-66.4]). Fifty-eight patients with available PET at diagnosis (PET0) and PETi data were included. PETi scans were analyzed according to Deauville 5-point scale (5-PS), and cut-off values for changes in maximum standardized uptake value [SUVmax], peak SUV [SUVpeak], metabolic tumour volume [MTV] and total lesion glycolysis index [TLG] between PETi and PET0 were computed using ROC analysis. Visual and semiquantitative data were compared with each other in the prediction of patient outcomes.

RESULTS

Semiquantitative analysis obtained a higher sensitivity for persistent/relapsed disease compared to the 5-PS (70% vs. 10%, respectively), but lower specificity. It also demonstrated better predictive performance for response to first-line therapy (negative predictive value >92%). The positive predictive value was similar for all five measurements. At 60 months of follow-up, there was a significant difference between the progression free survival (PFS) curves of patients with positive and negative PETi according to ΔSUVmax (56.9% vs. 88.0%, p<0.05), ΔSUVpeak (55.9% vs. 88.1%, p<0.05), ΔMTV (35.3% vs. 88.7%, p<0.05), and ΔTLG (42.4% vs. 88.1%, p<0.05). Statistical significance was not reached when considering 5-PS results.

DISCUSSION

PETi interpretation according to a semiquantitative approach appears to discriminate HL patients better than the visual 5-PS analysis. This could allow better detection of persistent or early relapsed disease, while a negative PETi result could support de-escalating therapy intensity.

Pancreatic adenocarcinoma metastasis to the oral cavity: A rare case report and literature review

A patient suffering from metastatic pancreatobiliary adenocarcinoma was referred to our hospital's stomatology department after a rapidly progressing swelling in the right mandibular angle, trismus and preauricular pain of 3-month duration. A mandible CT scan showed extensive bone rarefaction and a thickening of the contiguous soft tissues that involved the medial masseter and pterygoid muscle. The morphological findings and immunohistochemical profile were compatible with bone metastasis from pancreatic adenocarcinoma. Therefore, palliative treatment was proposed to the patient. Pancreatic cancer metastases to the oral cavity are extremely rare and characterized by its poor prognosis. Herein we describe the ninth case of metastatic spread to the jaw which is also remarkably the longest surviving reported case up to date.

Integrating a palliative approach into the healthcare provided by the French-African Pediatric Oncology Group's pilot units. Insights from a 3-year training program

Working alongside local stakeholders, members of the French-African Pediatric Oncology Group developed a 3-year program to train pediatric oncology teams from 15 French-speaking countries in Africa in using analgesics and providing palliative care. This program was rolled out in three phases: initial training, in situ assessment, and advanced training in selected topics. To access this program, multidisciplinary teams had to come up with a project to improve their existing palliative care and pain management practices, and commit themselves to implementing it. All the teams invited agreed to take part in the program, which explicitly broached a subject that is often avoided in oncology teaching. The first phase was rolled out in 2017, with 65 trainees from 19 units attending one of three sessions held in Dakar, Senegal, Abidjan, Côte d'Ivoire, and Rabat, Morocco. The subsequent assessment revealed that only half the teams had started to implement their projects. The advanced training phase was therefore adjusted accordingly. A collective training session held in Marseille was attended by 15 trainees from seven teams whose projects were already underway, while in situ mentoring was provided for six other teams, through French-African twinnings in four cases. The length and openness of the program meant that we were able to identify and share the units' diverse realities, and fine-tune their projects accordingly, as well as plan ways of continuing the training both locally and collectively.

En-face OCT and OCT angiography analysis of macular choroidal macrovessel

Purpose

To analyze en-face optical coherence tomography (OCT) and decorrelation signals on OCT angiography (OCTA) in two cases of macular choroidal macrovessel (MCM).

Observations

Case report. Both the 64-year-old and 71-year-old females presented for a routine evaluation, and multimodal imaging analysis, including color fundus photography, indocyanine green angiography (ICG), spectral-domain optical coherence tomography (SD-OCT) and OCTA, was performed to diagnose a MCM. En-face OCT, en-face OCTA and decorrelation signals were analyzed through the MCM. In both reported cases, color fundus photograph revealed a serpiginoid lesion in the temporal macula. Red-free imaging enhanced the appearance of this lesion resembling a dilated choroidal vessel. Cross-sectional OCT showed an enlarged choroidal vessel causing elevation of the retinal pigment epithelium (RPE) within the fovea. En-face OCTA with segmentation below the choriocapillaris enhanced the MCM delineation. En-face OCT with segmentation below the choriocapillaris showed MCM with a greater distinctness than the en-face OCTA imaging. Decorrelation signals were not observed within MCM on cross-sectional OCTA.

Conclusion and importance

En-face OCT and decorrelation signals on OCTA may have diagnostic value in distinguishing macular choroidal macrovessel from other choroidal vascular diseases.

Bacillus toyonensis BCT-7112T transient supplementation improves vaccine efficacy in ewes vaccinated against Clostridium perfringens epsilon toxin

AIM

The aim of the present study was to examine the vaccine immune response in ewes supplemented with Bacillus toyonensis BCT-7112^T during a period of 5-day supplementation before vaccination against a recombinant Clostridium perfringens epsilon toxin (rETX).

METHODS AND RESULTS

Ewes were vaccinated with 200 µg of rETX adjuvanted with 10% aluminium hydroxide. The treat group was orally supplemented with B. toyonensis BCT-7112^T (3 × 10⁸ viable spores) for 5 days prior to the first and second vaccination. Ewes supplemented with B. toyonensis BCT-7112^T showed higher neutralizing antibody titres than the non-supplemented ewes (P < 0·05), with an increase in serum levels for total IgG anti-rETX by 3·2-fold (P < 0·0001), and for both IgG isotypes IgG1 and IgG2 by 2·1-fold and 2·3-fold (P < 0·01), respectively, compared with the control group. The peripheral blood mononuclear cells of ewes in the supplemented group had a higher (P < 0·05) cytokine mRNA transcription levels for IL-2 (6·4-fold increase), IFN-γ (2·9-fold increase) and transcription factor Bcl6 (2·3-fold increase) compared with the control group.

CONCLUSION

We conclude that a 5 days of supplementation with B. toyonensis BCT-7112^T prior vaccination is sufficient to significantly improve the humoral immune response of ewes against C. perfringens recombinant ETX vaccine.

SIGNIFICANCE AND IMPACT OF THE STUDY

These findings open a new perspective in the utilization of B. toyonensis BCT-7112^T as an immunomodulator since a 5 days period of probiotic supplementation is sufficient to improve the vaccine immune response.

Influence of volumetric loading rate on aerobic sewage treatment for indigenous algal growth

Many rural areas of Latin America and the Caribbean (LAC) region are economically depressed. Rural sewage treatment in most areas of LAC is deficient or non-existent. Consequently, the possibility of generating economic revenue from treated sewage is an attractive option for deprived areas of developing countries. Given its peculiar characteristics, rural sewage may be coupled with biological systems such as algae for nutrient cycling. Acceptable algae growth and nutrient elimination were obtained from rural sewage whose treatment may have fallen short of current disposal standards. In this study, aerobic systems working on an 8-month cycle at three different volumetric loading rates (Bv) were assessed in relation to the lifetime growth of three algae strains native to Ecuador. Results indicate Chlorella sp. M2 as the optimal algal strain, with the highest growth rate at Bv of 1 g COD L^-1 d^{- 1} and a removal of organic-N (30%), PO₄ ^3--P (87%) and NH₄ ⁺-N (95%). Concomitantly, the kinetic constants of the sewage resulted in a low biomass yield coefficient, making the proposed system highly suitable for developing countries. Finally, the proposed partial recovery stream method, combining nutrient recovery with economic resource generation, appears to contain great potential.

Associations between anthropometric indicators in early life and low-grade inflammation, insulin resistance and lipid profile in adolescence

BACKGROUND AND AIMS

The long-term relations between excessive adiposity in early childhood and unfavourable cardiometabolic profiles in later ages are not yet completely understood. We aimed to assess the associations between birth weight (BW) and BMI from 6 months to 6 years of age, with biomarkers indicative of low-grade inflammation, insulin resistance and lipid profiles in adolescence.

METHODS AND RESULTS

Retrospective school-based study with 415 Portuguese adolescents (220 girls), mean age of 14.08 ± 1.6 years old. Anthropometric data from birth to 6 years old was extracted from individual child health book records. Actual weight and height were measured and BMI calculated. Participants were classified at each time point as normal weight or overweight according to WHO reference values. Biomarkers were obtained from venous blood samples. Linear regressions were used to explore the associations between the biomarkers and early life anthropometric indicators. From 2 years onwards, BMI associated positively with the inflammatory score and HOMA-IR in adolescence. Children who were overweight/obese from 2 to 6 years of age presented significantly higher inflammatory score and HOMA-IR later in adolescence. TC/HDL ratio was also positively associated with BMI from the age of 5 years onwards. The associations between BMI and cardiometabolic outcomes remained positive in adolescence, with overweight adolescents presenting a higher inflammatory score, HOMA-IR and TC/HDL than normal weight adolescents.

CONCLUSION

A high BMI from an early age was consistently associated with worse inflammatory and lipid profiles and insulin resistance in adolescence. No associations were found between BW and the same studied outcomes.

Benchmarking of the BITalino biomedical toolkit against an established gold standard

The low-cost multimodal platform BITalino is being increasingly used for educational and research purposes. However, there is still a lack of well-structured work comparing data acquired by this toolkit against a reference device, using established experimental protocols. This work intends to fill the said gap by benchmarking the performance of BITalino against the BioPac MP35 Student Lab Pro device. This work followed a methodical experimental protocol to acquire data from the two devices simultaneously. Four physiological signals were acquired: electrocardiography, electromyography, electrodermal activity and electroencephalography. Root mean square error and coefficient of determination were computed to analyse differences between BITalino and BioPac. Electrodermal activity signals were very similar for the two devices, even without applying any major signal processing techniques. For electrocardiography, a simple morphological comparison also revealed high similarity between devices, and this similarity increased after a common segmentation procedure was followed. Regarding electromyography and electroencephalography data, the approach consisted of comparing features extracted using common post-processing methods. The differences between BITalino and BioPac were again small. Overall, the results presented here show a close similarity between data acquired by the BITalino and by the reference device. This is an important validation step for all researchers working with this multimodal platform.

Fibrinogen-erythrocyte binding and hemorheology measurements in the assessment of essential arterial hypertension patients

Some studies have reported a positive association between plasma fibrinogen levels, erythrocyte aggregation and essential arterial hypertension (EAH). The aim of this study was to understand how the interaction between fibrinogen and its erythrocyte membrane receptor is altered in EAH. EAH patients (n = 31) and healthy blood donors (n = 65) were enrolled in the study. EAH patients were therapeutically controlled for the disease, presenting a systolic blood pressure between 108 and 180 mmHg and a diastolic blood pressure between 66 and 123 mmHg. Clinical evaluation included blood pressure monitoring, electrocardiography, echocardiography and blood cell count. The hemorheological parameters were also analyzed. Fibrinogen-erythrocyte binding force and frequency were evaluated quantitatively, at the single-molecule level, using atomic force microscopy (AFM). Changes in erythrocyte elasticity were also evaluated. Force spectroscopy data showed that the average fibrinogen-erythrocyte binding forces increase from 40.4 ± 3.0 pN in healthy donors to 73.8 ± 8.1 pN in patients with EAH, despite a lower binding frequency for patients compared to the control group (7.9 ± 1.6% vs. 27.6 ± 4.2%, respectively). Elasticity studies revealed an increase of erythrocyte stiffness in the patients. The stronger fibrinogen binding to erythrocytes from EAH patients and alteration in cell elasticity may lead to changes in the whole blood flow. The patients' altered hemorheological parameters may also contribute to these blood flow perturbations. The transient bridging of two erythrocytes, by the simultaneous binding of fibrinogen to both of them, promoting erythrocyte aggregation, could represent an important cardiovascular risk factor.

The Externalities of Advocacy: The High Cost of Standing Up for Patients' Dignity in Senegal

Background and context: In Senegal, pediatric oncology patients arrive at the hospital at advanced stages of disease. Their large tumors, as well as the side effects of chemotherapy make children experience intense pain. In this low-resource setting, morphine supply was quite irregular. Doctors don´t prescribe morphine due to shortages; but few prescriptions also lead to limited orders. A vicious circle with only 1 victim: the patient. Hearing children in pain was agonizing for everyone: patients, caregivers and healthcare practitioners. Aim: This advocacy narrative illustrates how the fight for access to morphine in pediatric oncology has led to both positive and negative externalities. We will highlight ways in which this fight for morphine has provoked political tensions moving the issue forward, but has also affected the careers of health workers involved. Strategy/Tactics: Morphine is a cheap drug, yet it is extremely regulated by international laws. It takes political will to influence national morphine orders. This advocacy strategy was built on raising awareness and setting morphine shortage on the political agenda. Not providing morphine in oncology goes against international standards of care. But most importantly, letting patients suffer without “existing” relief is a breach of basic human right to live - and also die - in dignity. Program/Policy process: Conversations began within the pediatric oncology department. Focus groups highlighted caregivers' feelings of powerlessness before their suffering child. Interviews with key informants (doctor and nurses) were instrumental to a widely diffused Human Rights Watch report exploring the medical and political causes to morphine supply shortages, as well as its psychological repercussions on patient care. A BBC documentary was broadcasted soon after. Subsequently, meetings were held between the Ministry of Health, the National Supply Pharmacy and leading local oncologists. Outcomes: Morphine orders were multiplied by 10, leading to much improved pain management for patients. However, Senegal was portrayed negatively on the international scenes, much to the Health Minister´s dismay. The consequences were incurred by the health workers who contributed to the international publications/reports. What was learned: Health practices can inform policy just like policy can inform health practices. It is a cyclical process. Creating advocacy coalitions and rallying the help of the international community are effective strategies. However, in the political arena, health workers need more than commitment to human rights and quality care. Even in democratic republics, systems can penalise outspoken activists. We have learned that health care practitioners (especially working in public settings) who wish improvement for their patients must learn to be tactical and diplomatic. International partners will return to their home countries, but local actors will pay the high cost of advocacy.

Fruit, vegetable consumption and blood pressure in healthy adolescents: A longitudinal analysis from the LabMed study

BACKGROUND AND AIMS

The associations between fruit and vegetable consumption and high blood pressure among adults are well studied. Nonetheless, data on the influence of a low consumption of fruit and vegetables on cardiovascular disease risk, particularly blood pressure, among healthy adolescents are scarce. Therefore, we aim to analyse the associations between fruit and/or vegetable intake and blood pressure over a two-year period in healthy adolescents.

METHODS AND RESULTS

As part of a cohort, 606 adolescents from the LabMed Physical Activity study were evaluated in 2011 (baseline) and 2013 (follow-up). Blood pressure was measured according to standardized procedures and fruit and vegetable consumption was assessed with a food frequency questionnaire. Anthropometric variables, socioeconomic status, pubertal stage and lifestyle determinants were gathered and used as confounders. Prospective associations between fruit and/or vegetable intake and blood pressure were examined using generalized linear models. Girls who consumed more fruit at baseline had a significant decrease in diastolic blood pressure at follow-up [unstandardized beta: -0.005 mmHg (95%CI: -0.01; -0.0002) (p = 0.038)].

CONCLUSION

In apparently healthy adolescents, fruit intake may already start to have an effect in blood pressure. Girls who consumed more fruit exhibited lower levels of diastolic blood pressure.

Longitudinal association between ideal cardiovascular health status and muscular fitness in adolescents: The LabMed Physical Activity Study

BACKGROUND AND AIMS

Muscular fitness is an emerging predictor for cardiovascular disease mortality. The ideal cardiovascular health metrics has been inversely related to a subsequent cardiometabolic health in adulthood. However, evidence regarding muscular fitness and ideal cardiovascular health in adolescents is scarce. This study aimed to examine the longitudinal association between ideal cardiovascular health index and muscular fitness.

METHODS AND RESULTS

This study cohort consisted of 331 adolescents (183 girls) from the LabMed Physical Activity Study who were followed from 2011 to 2013. Ideal cardiovascular health, as defined by the American Heart Association, was determined as meeting ideal health factors (total cholesterol, blood pressure, and glucose) and behaviors (smoking status, body mass index, physical activity, and diet). Handgrip strength and standing long jump tests assessed muscular fitness and were transformed into standardized values according to age and sex. ANCOVA showed a significant association between the accumulation of ideal cardiovascular health metrics at baseline and muscular fitness indices at follow-up (F_{(4, 322)} = 2.280, p = 0.04). In addition, the higher the number of ideal cardiovascular health metrics accumulated, the higher the likelihood of having a high muscular fitness over a two-year period (p for trend = 0.01), after adjustments for age, sex, pubertal stage and socioeconomic status and muscular fitness at baseline.

CONCLUSION

The ideal cardiovascular health status during adolescence was associated with high muscular fitness levels over a two-year period.

Essential arterial hypertension patients present higher cell adhesion forces, contributing to fibrinogen-dependent cardiovascular risk

The increase of erythrocyte aggregation by high fibrinogen levels may be an indicator of cardiovascular risk. γ' fibrinogen variant has been considered as a possible player in enhancing aggregation. Here, we assessed, at the single-cell level, the influence of fibrinogen on erythrocyte aggregation in essential arterial hypertension. We also aimed at understanding how γ' fibrinogen is altered in this disease. Using atomic force microscopy (AFM), we show that the work and force necessary for erythrocyte-erythrocyte detachment is higher for patients than for healthy donors, with these parameters further increasing in both groups when higher fibrinogen concentrations are present. This can be associated with changes in blood flow, due to transient bridging of two erythrocytes by fibrinogen, representing an important cardiovascular risk factor. γ' fibrinogen can influence the increased risk in essential arterial hypertension, as we demonstrate that its levels are significantly increased in these patients' blood. Nevertheless, this cannot be the only cause for the changes observed in the AFM data.

[Fatal female genital mutilation in a 10-year-old girl]

Female genital mutilation (FGM) comprises all procedures involving partial or total removal of the external genitalia and/or any other procedures affecting the female genitalia, for cultural or religious reasons or for nontherapeutic purposes in general. FGM is responsible for a number of short-, medium-, and long-term complications that can engage the vital and functional prognosis, especially in African countries. We report on a case in a 10-year-old girl who underwent genital mutilation, a traditional type of total excision during the neonatal period. She was followed for urethral meatus stenosis, which then was complicated by obstructive chronic kidney failure and urinary sepsis, whose progression was fatal.

Muscular fitness, adherence to the Southern European Atlantic Diet and cardiometabolic risk factors in adolescents

BACKGROUND AND AIM

Muscular fitness and an adherence to the Southern European Atlantic Diet (SEADiet) have been inversely associated with cardiometabolic risk. Our aim was to assess the independent and combined associations of muscular fitness and adherence to the SEADiet on cardiometabolic risk in adolescents.

METHODS AND RESULTS

A total of 467 Portuguese adolescents (275 girls) participated in this cross-sectional study. Sum of the Z-Scores of Curl-Up and Push-Up tests was used to create a muscular fitness score. Adherence to SEADiet was obtained using a food frequency questionnaire. A cardiometabolic risk score was computed from sum of Z-score of triglycerides, systolic blood pressure, total cholesterol/HDL ratio, HOMA-IR and waist circumference. Adolescents with low muscular fitness and low adherence to the SEADiet had the poorest cardiovascular profile F_(5, 452) = 5.074 (p < 0.001) and the highest odds of having a high cardiometabolic risk score (OR = 4.5; 95% CI: 2.1-14) when compared to those with High muscular fitness/High adherence to the SEADiet after adjustments for age, sex, pubertal stage, socioeconomic status, total energy intake, low-energy reporter and cardiorespiratory fitness.

CONCLUSIONS

Our findings seem suggest that improving muscular fitness as well as an adherence to the SEADiet could be an important strategy to reduce clustered cardiometabolic risk in youth.

[Pathological profiles of retinoblastoma in Senegal]

OBJECTIVES

Describe the macroscopic and microscopic profiles of retinoblastoma (RB) in Senegal and correlate histological criteria with progression to establish severity factors.

METHODOLOGY

We realized a retrospective study over 10 years (January 2005-December 2014). Only patients (n=67) who underwent histological analysis of the enucleation specimen (n=68) were followed until the end of the study.

RESULTS

The tumor measured an average of 3.8cm (2/4.5). Endophytic tumor development was observed in 55 cases (80.8%), exophytic in 6 cases (8.9%) and mixed in 7 cases (10.3%). Retinal detachment was present in 13 cases (19.2%). The RB was well differentiated in 11 cases (16.2%), moderately differentiated in 31 cases (45.6%) and undifferentiated in 26 cases. Optic nerve (ON) invasion was present in 18 cases (26.5%). The tumor was extraretinal in 37 cases (54.4%). The anterior chamber was invaded in 6 cases (8.8%). The global survival at 2 years was 84% and 70% at 5 years. On multivariate analysis, well differentiated tumors and stage pT1 were associated with remission. Retrolaminar ON invasion, massive choroidal invasion and stage pT3 were risk factors for recurrence. Poor tumor differentiation, invasion of the ON resection margin, tumor invasion through the sclera, and stage pT4 were predictive of death.

CONCLUSION

The pathologist is a principal actor in the management of RB because his account guide the post-surgical management strategy.

Generalized Bullous Fixed Drug Eruption due to Bromhexine

We describe a patient with a generalized bullous form of Fixed Drug Eruption (FDE) induced by bromhexine, a commonly used drug for respiratory symptoms. This is a rare association and generalized bullous FDE is also very rare. We emphasize the importance of patch tests in identifying the culprit drug.

Association between serum adiponectin levels and muscular fitness in Portuguese adolescents: LabMed Physical Activity Study

BACKGROUND AND AIM

Paradoxically, recent investigations have showed that adiponectin levels are inversely associated with muscle strength. However, to date, there is a lack of knowledge on the relationship between muscular fitness (MF) and adiponectin levels in adolescents. We aimed to examine the independent associations between MF and adiponectin levels in adolescents, controlling for several potential confounders.

METHODS AND RESULTS

This is a cross-sectional analysis with 529 Portuguese adolescents aged 12-18 years. A MF score was computed as the mean of the handgrip strength and standing long jump standardized values by age and gender. We measured fasting glucose, insulin, HDL-cholesterol, C-reactive protein and adiponectin. Linear regression analysis showed a significant inverse association between adiponectin (Z-score by age and sex) and MF score, after adjustments for age, sex, pubertal stage, socioeconomic status, adherence to the Mediterranean diet, body mass index, HOMA-IR, HDL-cholesterol, C-reactive protein and cardiorespiratory fitness (unstandardized β = -0.176; p < 0.005). Analysis of covariance showed a significant difference between the Low MF/Non-overweight group and the High MF/Non-overweight Group (p < 0.05) and between the Low MF/Non-overweight and High MF/Overweight Group (p < 0.05) (F (5, 523) = 2.262, p = 0.047).

CONCLUSION

Adiponectin circulating levels are inversely and independently associated with MF. In non-overweight adolescents, those with high levels of MF presented lower levels of adiponectin compared to those with Low MF. Likewise, overweight adolescents with High MF presented lower levels of serum adiponectin than non-overweight adolescents with Low MF.

Why Portugal is pushing towards migration?

Background

International professional mobility is a reality, people have skills they can put in the global marketplace. The increasing migration of health professionals to wealthy countries is a phenomenon known as “brain drain”.

Objectives/Aims

This work aims to present the push factors that pressure people to migrate from Portugal.

Methods

A cross-sectional survey was carried out with the psychiatric trainees in Portugal. A self-administered structured questionnaire was distributed to collect psychiatry trainees’ demographic and educational characteristics.

Results

In Portugal, the majority of trainees have a Portuguese citizenship. Almost 2/3 did not have a short-mobility experience, and the majority never migrated to another country. Less than half consider staying in Portugal in the next years, and nearly 4/5 have considered leaving the country. Working conditions ranked first as the priority condition to be improved in psychiatry in Portugal, followed by financial conditions. In fact, an attractive job for psychiatry trainees in Portugal must have as the most important feature a pleasant work environment.

Conclusions

An alarming percentage of psychiatry trainees from Portugal intend to migrate. Impact on future career, financial conditions of doctors, job opportunities and better working conditions were some of the motivating factors behind the migration.

Boderline versus personality

Introduction

Latest classifications led to an inflamed debate urging for change or validation in the way personality disorders are classified. The placement in psychiatric classifications of several personality disorders, particularly Borderline Personality Disorder (BPD), is also a matter of discussion.

Objectives and aims

The present work aims to question BPDs place in classification alongside with other personality disorders, rather than focusing on the algorithms used to classify it. The authors review updated literature on core features of the disorder collected from online scientific databases.

Results

Studies reveal that the stability of the diagnosis of BPD over the longer term is less than what standard general definitions of personality disorders would appear to require. It is a chronic and debilitating syndrome with severe functional and psychosocial impairment that remain relevant when comparing to other personality disorders. Additionally, these measures show further declines over time in spite of improvement in psychopathology, in contrast to what happens with other personality disorders. Several misconceptions may have led to the placement of BPD on former axis II, namely being a direct consequence of trauma and merely explained by environmental factors. However, recent research on heritability shows the contrary and several neurobiological markers suggest it has got a nature of its own.

Conclusion

BPD is probably the most studied and validated personality disorder and has substantially greater empirical basis, clinical significance and public health implications, being both enduring and distinct from other personality disorders. We suggest the placement of BPD as major psychiatric disorder in classifications.

Gut Feeling

Introduction

There is growing evidence of the importance of nutrition in mental disorders. Gut microbiota, influenced by environmental factors such as diet and stress, has been proposed as one of the players on a dynamic called gut-brain axis, which is thought to have an influence on behaviour and mental health.

Objectives and aims

To summarize recent evidence on the topic, and its potential role in psychiatric interventions.

Methods

The authors review updated literature collected from online scientific databases.

Results

The development of the brain itself has been shown to be influenced by the gut microbiome. Research demonstrates that the composition of the microbiota has influence on behaviour through neuroendocrine and other neuroactive messengers production by the bacteria within the gut lumen. Studies in germ-free animals, animals exposed to bacterial infections, probiotic suplements or antibiotic drugs suggest a role for the gut microbiota in the regulation of anxiety, mood, cognition and pain. The gut microbiome has been implicated in brain disorders including anxiety and depression, multiple sclerosis, Alzheimer's disease, Parkinson's disease, and autism.

Conclusions

The treatment of mental disorders is usually based on pharmacological and psychotherapeutic interventions, and little attention is given to dietary interventions. The emerging field of research focused on the human microbiome suggests an important role for the gut microbiota in influencing brain development, behaviour and mood in humans, and points new strategies for developing novel therapeutics for mental disorders.
