ABSTRACT
Background. Scar appearance is an important outcome in abdominoplasty surgery, and its asymmetry can have a significant impact on patient and surgeon satisfaction. Here, we compared the scar symmetry reached with a ruler specially designed for the preoperative marking in abdominoplasty to the classic preoperative incision marking. Methods. In this randomized, uni-blind study, 42 patients were allocated to 2 different groups. Group 1 patients had their preoperative marking made by a group of surgeons that used the classic technique as described by Baroudi (n = 21), and Group 2 patients received their preoperative marking by another group of surgeons, using a ruler specially designed to fit the abdominal contour (n = 21). Patients were evaluated using a standard questionnaire that collected information about general patient's characteristics. On the follow-up period, we evaluated the presence of late surgical complications, need for revision surgery, patient's satisfaction concerning the postoperative scar, and 4 distances were measured in both groups to assess symmetry. Statistical analysis was made. Results. A total of 42 patients underwent abdominoplasty and were evaluated on the follow-up period (mean time: 4 months). The mean difference of corresponding measures on each side (A-B vs. A-B' and A-C vs. A-C') was higher in Group 1 comparing to Group 2. The level of correlation between corresponding measurements was higher in Group 2. Better satisfaction regarding the scar symmetry was achieved in Group 2, being this result statistically significant (P = .004). Conclusions. The use of the specialized ruler may help surgeons achieve a better scar symmetry with higher patient satisfaction.

This paper is a systematic review on the reference values and changes in infant sleep-wake behaviour during the first 12 months of life. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Seventy-four papers were included, and the reference values and changes in sleep-wake behaviour during the first 12 months of life were identified. Sleep duration during the 24-h period, and day and sleep periods during the night decreased over the first 12 months of life. Night wakings and bedtime/sleep-onset time decreased, while the longest sleep period increased at night during the first 6â months. High discrepancy was noted between studies in the reference values of sleep-wake behaviour, while more congruence was noted regarding changes, especially those occurring in the first 6 months of life. Several methodological differences were identified between studies and may partially explain inconsistencies in the results, including the assessment of different sleep-wake behaviours, the focus on specific ages or age ranges, the use of self-report, observational or direct measures, the recruitment of small or large representative samples, and the countries where the research was conducted. These aspects should be considered in future research and caution should be taken when generalizing results from studies with diverse methodological characteristics. Nonetheless, this review identifies normative reference values and the changes occurring in infant sleep-wake behaviour, and could inform both practitioners and researchers, helping them identify infants with sleep delays or problems.

BACKGROUND: Recent data suggest that cognitive reserve modulates the adverse effects of multiple sclerosis (MS) pathology on cognitive functioning; however, the protective effects of education in MS are still unclear. OBJECTIVE: To explore education as an indicator of cognitive reserve, while controlling for demographic, clinical and genetic features. METHODS: A total of 419 MS patients and 159 healthy comparison (HC) subjects underwent a comprehensive neuropsychological (NP) assessment, and answered the Hospital Anxiety and Depression Scale. Based on the HC data, MS patients' NP scores were adjusted for sex, age and education; and the estimated 5(th) percentile (or 95(th) percentile, when appropriate) was used to identify any deficits. Patients also performed the Mini-Mental State Examination (MMSE); and their human leucocyte antigen HLA-DRB1 and apolipoprotein E (ApoE) genotypes were investigated. RESULTS: Patients with higher education were less likely (p < 0.05) to have cognitive deficits than those with lower education, even when controlling for other covariates. Other significant predictors of cognitive deficit were: age, Expanded Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), and a progressive course. No significant association was found with the HLA-DRB1*15:01 or ApoE ε4 alleles. CONCLUSIONS: These results provide support to the use of education as a proxy of cognitive reserve in MS and stress the need to take into account education when approaching cognition in MS.

The aims of this study were to characterize the exposure of pregnant women living in Portugal to 3-phenoxybenzoic acid (3-PBA) and to evaluate the association of this exposure with maternal outcomes and newborn anthropometric measures. We also aimed to compare exposure in summer with exposure in winter. Pregnant women attending ultrasound scans from April 2018 to April 2019 at a central hospital in Porto, Portugal, were invited to participate. Inclusion criteria were: gestational week between 10 and 13, confirmed fetal vitality, and a signature of informed consent. 3-PBA was measured in spot urine samples by gas chromatography with mass spectrometry (GC-MS). The median 3-PBA concentration was 0.263 (0.167; 0.458) µg/g creatinine (n = 145). 3-PBA excretion was negatively associated with maternal pre-pregnancy body mass index (BMI) (p = 0.049), and it was higher during the summer when compared to winter (p < 0.001). The frequency of fish or yogurt consumption was associated positively with 3-PBA excretion, particularly during the winter (p = 0.002 and p = 0.015, respectively), when environmental exposure is low. Moreover, 3-PBA was associated with levothyroxine use (p = 0.01), a proxy for hypothyroidism, which could be due to a putative 3-PBA-thyroid hormone antagonistic effect. 3-PBA levels were not associated with the anthropometric measures of the newborn. In conclusion, pregnant women living in Portugal are exposed to 3-PBA, particularly during summer, and this exposure may be associated with maternal clinical features.
ABSTRACT
BACKGROUND: The loss of response to adalimumab (ADL) has been related to low serum concentrations at trough. Currently, most methods commercially available for the quantification of ADL are enzyme-linked immunosorbent assay (ELISA) based, with a turnaround time of approximately 8âh, delaying the target dosage adjustment to the subsequent infusion. In this study, we aimed to evaluate the performance of the newly available rapid-test ADL quantification assay by comparing it with three established ELISA methods, using spiked samples and a set of clinical samples. METHODS: Spiked samples from control donors and 120 serum samples from inflammatory bowel disease (IBD) patients undergoing ADL therapy were quantified using lateral flow Quantum Blue® Adalimumab and, the ELISA formats from Immundiagnostik, R-Biopharm and an in-house assay. RESULTS: The rapid-test assay had intraclass correlation coefficients of 0.590, 0.864 and 0.761 when comparing with the Immundiagnostik, R-Biopharm and in-house assays, respectively. For the five therapeutic windows, the accuracy was high: ADL rapid test compared with the Immundiagnostik (58-88%); R-Biopharm, 68-89%; and in house, 60-88%; and kappa statistics revealed 0.492-0.602, 0.531-0.659 and 0.545-0.682, respectively. CONCLUSIONS: The Quantum Blue® Adalimumab assay can replace the commonly used ELISA-based ADL quantification kits and it is a reliable alternative to these methods. This rapid-test assay enables the quantitative determination of ADL serum trough level in only 15âmin. The developed assay allows measurement of ADL over a wide range. Hence, it represents a valuable tool for the clinician to assess the ADL trough level.
ABSTRACT
BACKGROUND: Although there is some evidence suggesting that certain viruses may be involved in the onset of inflammatory bowel disease (IBD), data regarding viral prevalence and viral load in blood and mucosa of patients with IBD are scarce. The main aim of this study is to evaluate the prevalence and viral load of common Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpes virus 6 in blood and mucosa of adult patients with endoscopic active IBD. METHODS: From January to December 2014, ulcerative colitis and Crohn's disease patients with active endoscopic disease were consecutively enrolled. Subjects undergoing colonoscopy for colorectal cancer screening served as healthy controls (HCs). Paired blood and mucosal samples from each patient and HC were collected for EBV, CMV, and human herpes virus 6 quantitative real time polymerase chain reaction assessment of the viral load. RESULTS: One hundred forty-five subjects were included; 95 IBD patients with active endoscopic disease (43 ulcerative colitis and 52 Crohn's disease) and 50 healthy subjects. CMV and EBV DNA were detected more frequently in the mucosa of patients with IBD compared with HCs (CMV P = 0.017; EBV P < 0.001), irrespective of IBD type. The frequency of human herpes virus 6 DNA detection both in the blood and in the mucosa did not differ between patients with IBD and HCs. EBV median viral load was similar in the inflamed and noninflamed mucosa was not affected by the use of immunomodulators and/or anti-tumor necrosis factor alpha agents, and did not correlate with endoscopic disease activity. CONCLUSIONS: EBV, and to a lesser extent CMV, were more prevalent in patients with IBD than in HCs. Mucosal viral load was not influenced by the therapeutic regimen, did not differ between inflamed and noninflamed mucosa, and did not seem to be influenced by the endoscopic activity of the disease, suggesting that EBV may be more involved in the onset of IBD than in its severity and clinical evolution.

BACKGROUND AND AIMS: The definition of early therapeutic strategies to control Crohn's disease aggressiveness and prevent recurrence is key to improve clinical practice. This study explores the impact of early surgery and immunosuppression onset in the occurrence of disabling outcomes. METHODS: This was a multicentric and retrospective study with 754 patients with Crohn's disease, who were stratified according to the need for an early surgery (group S) or not (group I) and further divided according to the time elapsed from the beginning of the follow-up to the start of immunosuppression therapy. RESULTS: The rate of disabling events was similar in both groups (S: 77% versus I: 76%, P = 0.700). The percentage of patients who needed surgery after or during immunosuppression therapy was higher among group S, both for first surgeries after the index event (38% of groups S versus 21% of group I, P < 0.001) and for reoperations (38% of groups S versus 12% of group I, P < 0.001). The time elapsed to reoperation was shorter in group I (HR = 2.340 [1.367-4.005]), stratified for the onset of immunosuppression. Moreover, reoperation was far more common among patients who had a late start of immunosuppression (S36: 50% versus S0-6: 27% and S6-36: 25%, P < 0.001) and (I36: 16% versus I0-6: 5% and I6-36: 7%, P < 0.001). CONCLUSIONS: Although neither early surgery nor immunosuppression seem to be able to prevent global disabling disease, an early start of immunosuppression by itself is associated with fewer surgeries and should be considered in daily practice as a preventive strategy.

BACKGROUND: Endoscopic recurrence after surgery for Crohn's disease (CD) is high, and it has important prognostic value. Crohn's disease will recur in the majority of patients after surgery. Fecal calprotectin (FC) and lactoferrin (FL) have attracted interest in the postoperative setting for predicting relapse. We have evaluated the accuracy of FC and FL in diagnosing endoscopic recurrence (ER) using the modified Rutgeerts score (MRS) compared with the Rutgeerts score (RS). METHODS: A series of consecutive patients who underwent ileocolonic resection for Crohn's disease were evaluated. Biomarkers, clinical indexes, and fecal markers were recorded on the day of ileocolonoscopy. ER was defined as a MRS ≥ i2b or a RS ≥ i2. RESULTS: Ninety-nine patients were included in this prospective cohort. The median time between surgery and colonoscopy was 87.5 months (IQR, 31-137). FC and FL levels were higher in patients with ER than in those in remission (Median FC, 196.5 µg/g [IQR, 96-634 µg/g] versus 42.1 µg/g [IQR 19-91.60 µg/g; P < 0.001]; Median FL, 23.27 µg/g [IQR 8.9-47.8 µg/g] versus 2 µg/g [IQR 0.9-7.26 µg/g; P < 0.001]). Using the MRS, 34% of patients presented with ER compared with 76% if the RS was used. The RS performed worse than the MRS with a decrease in sensitivity (74% versus 48% for FC and 85% versus 55% for FL) and in NPV (91% versus 33% for FC, and 90% versus 37% for FL). Furthermore, the accuracy of the MRS was higher than that of the RS (75% versus 55%). CONCLUSIONS: Both FC and FL proved to correlate well with endoscopic findings in the evaluation of Crohn's disease after surgery. Both markers predicted recurrence with greater accuracy when the MRS was used. Fecal markers can be used to monitor disease recurrence after intestinal resection, with patients being selected to undergo further endoscopic evaluation.

STUDY OBJECTIVE: This study analyzes differences between adolescent and adult pregnant women and the contribution of maternal age to maternal adjustment and maternal attitudes during pregnancy. DESIGN, SETTING, AND PARTICIPANTS: A sample of 398 Portuguese pregnant women (111 younger than 19 years) was recruited in a Portuguese Maternity Hospital and completed the Maternal Adjustment and Maternal Attitudes Questionnaire between the 24(th) and 36(th) weeks of gestation. MAIN OUTCOME MEASURES: Maternal Adjustment and Maternal Attitudes Questionnaire(1) RESULTS: Adolescent pregnant women show lower maternal adjustment (poorer body image and worse marital relationship) and poorer maternal attitudes (more negative attitudes to sex) than adult pregnant women. When controlling for socio-demographics, age at pregnancy predicts poorer body image and more negative attitudes to sex, but not a worse marital relationship, more somatic symptoms or negative attitudes to pregnancy and the baby. A worse marital relationship was better predicted by living without the partner, and more somatic symptoms and negative attitudes to pregnancy and the baby was predicted by higher education. CONCLUSION: Adolescent pregnant women show lower maternal adjustment and poorer maternal attitudes than adult pregnant women according to socio-demographics and unfavorable developmental circumstances.

BACKGROUND: Although several studies have demonstrated the economic advantages of peritoneal dialysis (PD) over hemodialysis (HD), few reports in the literature have compared the costs of HD and PD access. The aim of the present study was to compare the resources required to establish and maintain the dialysis access in patients who initiated HD with a tunneled cuffed catheter (TCC) or an arteriovenous fistula (AVF) and in patients who initiated PD. METHODS: We retrospectively analyzed the 152 chronic kidney disease patients who consecutively initiated dialysis treatment at our institution in 2008 (HD-AVF, n = 65; HD-CVC, n = 45; PD, n = 42). Detailed clinical and demographic information and data on access type were collected for all patients. A comprehensive measure of total dialysis access costs, including surgery, radiology, hospitalization for access complications, physician costs, and transportation costs was obtained at year 1 using an intention-to-treat approach. All resources used were valued using 2010 prices, and costs are reported in 2010 euros. RESULTS: Compared with the HD-AVF and HD-TCC modalities, PD was associated with a significantly lower risk of access-related interventions (adjusted rate ratios: 1.572 and 1.433 respectively; 95% confidence intervals: 1.253 to 1.891 and 1.069 to 1.797). The mean dialysis access-related costs per patient-year at risk were 1171.6 [median: 608.8; interquartile range (IQR): 563.1 - 936.7] for PD, 1555.2 (median: 783.9; IQR: 371.4 - 1571.7) for HD-AVF, and 4208.2 (median: 1252.4; IQR: 947.9 - 2983.5) for HD-TCC (p < 0.001). In multivariate analysis, total dialysis access costs were significantly higher for the HD-TCC modality than for either PD or HD-AVF (ß = -0.53; 95% CI: -1.03 to -0.02; and ß = -0.50; 95% CI: -0.96 to -0.04). CONCLUSIONS: Compared with patients initiating HD, those initiating PD required fewer resources to establish and maintain a dialysis access during the first year of treatment.

OBJECTIVE: To review the literature on the association between breastfeeding and postpartum depression. SOURCES: A review of literature found on MEDLINE/PubMed database. SUMMARY OF FINDINGS: The literature consistently shows that breastfeeding provides a wide range of benefits for both the child and the mother. The psychological benefits for the mother are still in need of further research. Some studies point out that pregnancy depression is one of the factors that may contribute to breastfeeding failure. Others studies also suggest an association between breastfeeding and postpartum depression; the direction of this association is still unclear. Breastfeeding can promote hormonal processes that protect mothers against postpartum depression by attenuating cortisol response to stress. It can also reduce the risk of postpartum depression, by helping the regulation of sleep and wake patterns for mother and child, improving mother's self-efficacy and her emotional involvement with the child, reducing the child's temperamental difficulties, and promoting a better interaction between mother and child. CONCLUSIONS: Studies demonstrate that breastfeeding can protect mothers from postpartum depression, and are starting to clarify which biological and psychological processes may explain this protection. However, there are still equivocal results in the literature that may be explained by the methodological limitations presented by some studies.

OBJETIVO: Revisar a literatura sobre a associação entre a amamentação e a depressão pós-parto. FONTES: Uma revisão da literatura encontrada na base de dados MEDLINE/Pub-Med. RESUMO DOS ACHADOS: A literatura mostra, de forma consistente, que a amamentação fornece uma ampla quantidade de benefícios tanto para a criança quanto para a mãe. Ainda são necessárias mais pesquisas sobre os benefícios psicológicos para a mãe. Alguns estudos apontam que a depressão na gravidez é um dos fatores que pode contribuir para a não amamentação. Outros estudos sugerem, também, uma associação entre amamentação e depressão pós-parto, não estando clara ainda a direção dessa associação. A amamentação pode promover processos hormonais que protegem as mães contra a depressão pós-parto por atenuar a resposta do cortisol ao estresse. E isso também pode reduzir o seu risco, por auxiliar na regulação dos padrões do sono e vigília da mãe e do filho, melhorando a autoeficácia e o envolvimento emocional da mãe com a criança, reduzindo as dificuldades de temperamento e promovendo uma melhor interação entre eles. CONCLUSÕES: A pesquisa aponta que a amamentação pode proteger as mães da depressão pós-parto e começa a esclarecer que processos biológicos e psicológicos podem explicar essa proteção. Contudo, ainda existem resultados ambíguos na literatura que poderão ser explicados pelas limitações metodológicas apresentadas por alguns estudos.
