We aim to review the available literature on patients with esophageal cancer treated with robot-assisted (RAME) or video-assisted McKeown's esophagectomy (VAME), to compare the efficacy and safety of the two approaches. Original research studies that evaluated perioperative and oncologic outcomes of RAME versus VAME were identified, from January 1990 to July 2022. The 90-day mortality, the R0 resection rate, the dissected lymph nodes, the perioperative parameters, and the complications were calculated according to a fixed and a random effect model. The Q statistics and I2 statistic were used to test for heterogeneity among the studies. Seven studies were included, incorporating a total of 1617 patients treated with RAME or VAME. The 90-day mortality was similar between the two groups. No difference was found regarding the R0 resection rate and the number of dissected lymph nodes. In addition, the perioperative parameters, along with the total complications were similar between RAME and VAME. Nonetheless, the incidence of postoperative pneumonia was higher in the VAME group (OR0.67 [95% CI 0.49, 0.93]; p = 0.02). Finally, our outcomes were further validated by sensitivity analysis including only studies performing propensity score-matched analysis. Our meta-analysis showed that RAME was equivalent to VAME in terms of safety, feasibility, and oncologic adequacy. These results should be interpreted with caution due to the small number of included studies. New Randomized Controlled trials, that are currently active, will provide further evidence with greater clarity to assess the effectiveness and safety of RAME for esophageal cancer.Protein-protein interactions (PPIs) play crucial roles in many cellular processes and their deregulation often leads to cellular dysfunctions. One promising way to modulate PPIs is to use peptide derivatives that bind their protein target with high affinity and high specificity. Peptide modulators are often designed using secondary structure mimics. However, fragment-based design is an alternative emergent approach in the PPI field. Most of the reported computational fragment-based libraries targeting PPIs are composed of small molecules or already approved drugs, but, according to our knowledge, no amino acid based library has been reported yet. In this context, we developed a novel fragment-based approach called Des3PI (design of peptides targeting protein-protein interactions) with a library composed of natural amino acids. All the amino acids are docked into the target surface using Autodock Vina. The resulting binding modes are geometrically clustered, and, in each cluster, the most recurrent amino acids are identified and form the hotspots that will compose the designed peptide. This approach was applied on Ras and Mcl-1 proteins, as well as on A[Formula see text] protofibril. For each target, at least five peptides generated by Des3PI were tested in silico the peptides were first blindly docked on their target, and then, the stability of the successfully docked complexes was verified using 200 ns MD simulations. Des3PI shows very encouraging results by yielding at least 3 peptides for each protein target that succeeded in passing the two-step assessment.
Some research has suggested a possible role for past infection in the development of preeclampsia. The objective of this study was to explore the role of Helicobacter pylori, cytomegalovirus, and Chlamydophila pneumoniae in the development of preeclampsia in a prospective pregnancy sample.
We conducted a nested case-control study in The Archive for Child Health (ARCH), a pregnancy cohort of 867 unselected women enrolled at the first prenatal visit with archived blood and urine in pregnancy. We matched 21 cases of preeclampsia to 52 unaffected controls on maternal age (±4 years), race, parity, and gestational age at blood draw. Using conditional logistic regression, we examined theassociation between preeclampsia status and immunoglobulins G (IgG) tested by indirect ELISA to each of the three microorganisms, adjusting for potential confounders.
No significant difference was found between cases and controls. The unadjusted odds ratio was 1.5 (95%CI 0.2-9.1), 0.6 (95%CI 0.2-1.9), and 1.9 (95%CI 0.6-5.6) foce of these infections.VvTOR interacts with VvSnRK1.1 and regulates sugar accumulation and sugar-related genes expression in grape. Target of rapamycin (TOR) and sucrose-non-fermenting-related protein kinase 1.1 (SnRK1.1) both are critical proteins in plant sugar metabolism. Glucose-TOR signaling dictates transcriptional reprogramming of gene sets involved in central and secondary metabolism, cell cycle, transcription, signaling, transport and folding. SnRK1.1 is involved in sucrose-induced hypocotyl elongation. However, the relationship of TOR and SnRK1.1 in regulating sugar metabolism is unclear. In the study, we utilized grape (Vitis vinifera) calli to explore the relationship between TOR and SnRK1.1 in the sugar metabolism. We found that VvTOR interacted with VvSnRK1.1. By subcellular localization, VvTOR was found in the nucleus and cell membrane. Transgenic grape calli achieved by Agrobacterium-mediated transformation contained less glucose compared to WT calli. The fructose contents were markedly increased in the overexpressing VvTOR (OE-VvTOR), OE-VvTOR + RNAi-VvSnRK1.1 and RNAi-VvTOR + OE-VvSnRK1.1 transgenic calli. Sucrose contents were significantly increased in the OE-VvTOR transgenic calli and reduced in the OE-VvTOR + RNAi-VvSnRK1.1 transgenic calli, which implied that the pathway of VvTOR improving sucrose content might need the expression of VvSnRK1.1. VvTOR interacted with VvSnRK1.1 and regulated sugar metabolism in grape. These results suggest that there is a crosstalk between TOR and SnRK1.1 in plant sugar metabolism.Aging is accompanied by a low-grade proinflammatory status that plays a role in age-related vascular alterations. selleck Syndecan-4 (SDC4) is a key component of the endothelial glycocalyx, and its extracellular domain can be shed by matrix metalloproteinase-9 (MMP-9). In vitro studies demonstrated that MMP-9-mediated shedding of SDC4 is induced by tumor necrosis factor-α (TNF- α) in human endothelial cells. However, the relationship between circulating shed SDC4, systemic inflammation, and age-related vascular alterations remains unknown. Here, we used linear regression models to examine the associations of serum SDC4 levels with cardiovascular hemodynamic phenotypes, serum MMP-9, and serum TNF-α and inteleukin-6 in healthy older women (n = 74). Serum SDC4 was not associated with proinflammatory cytokines or arterial elasticity. Nevertheless, we found significant correlations of SDC4 with MMP-9, heart rate, left ventricular ejection time, systemic vascular resistance, and blood pressure. Our preliminary evidence suggests that systemic inflammation might not induce SDC4 shedding in healthy aging.Tyrosine kinase inhibitors (TKIs) have revolutionized the treatment of chronic myeloid leukemia (CML). However, TKI-related chronic renal toxicity has been reported, particularly in patients with hypertension. We assessed whether incidental use of specific types of antihypertensive drugs, including renin-aldosterone-angiotensin system inhibitors (RAASis), affects the change in estimated glomerular filtration rate (eGFR) during TKI treatment. We retrospectively analyzed all eGFR measurements during TKI treatment for 142 CML patients at Kyushu University Hospital, estimating the rate of eGFR change using a mixed-effects model. Overall, a significant interaction was found between the type of antihypertensive medication used and the yearly change in eGFR (P less then 0.01), with RAASi users exhibiting the most rapid decrease in eGFR (- 5.5%/year). The analysis by TKI used showed that the interaction was significant only in imatinib and bosutinib users (P less then 0.01 and P = 0.04, respectively). The yearly rate of eGFR decrease was the most notable in RAASi users, at - 5.7 (- 6.6, - 4.9) and - 10.1 (- 12.3, - 7.9) for imatinib and bosutinib users, respectively. Our findings indicate that eGFR should be carefully monitored in patients taking these TKIs.Bacterial meningitis is a rare but severe infectious complication after hematopoietic stem cell transplantation. However, its clinical features were previously not clear. We reviewed the cases of 7 patients diagnosed with bacterial meningitis with a positive cerebrospinal fluid culture among 1147 patients who underwent cord blood transplantation (CBT) at our institution between September 2007 and September 2020. The diagnosis was made on day + 5- + 45, and 5 patients developed bacterial meningitis before neutrophil engraftment. The causative organisms were all Gram-positive cocci Enterococcus faecium and Enterococcus gallinarum (2 patients each), and Staphylococcus haemolyticus, Streptococcus mitis/oralis, and Rothia mucilaginosa (1 patient each). Six patients developed bacterial meningitis secondary to prior or concomitant bacteremia caused by the same bacterium. Five patients had received anti-MRSA agents at onset vancomycin in 3, teicoplanin in 1, and daptomycin in 1. After diagnosis of bacterial meningitis, linezolid was eventually used for 6 patients. Two patients with E. gallinarum were alive at day + 1380 and + 157 after CBT, respectively, whereas 5 patients died 17-53 (median 43) days after the onset of bacterial meningitis. Breakthrough meningitis in CBT can occur even during the use of anti-MRSA drugs, and intensive antibiotic treatment is necessary.
To test whether an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) program for older adults attenuates symptoms of depression and anxiety.
Adults aged ≥ 55 with insomnia were randomized to SHUTi-OASIS (Sleep Healthy Using the Internet for Older Adult Sufferers of Insomnia and Sleeplessness; N = 207) or Patient Education (PE; N = 104). Depression and anxiety were assessed (HADS-D and HADS-A, respectively) at baseline, post-assessment, and 6- and 12-month follow-ups.
Multilevel modeling of HADS-D showed a condition by time interaction (F[3,779] = 3.23, p = .02) SHUTi-OASIS participants reported lower symptoms than PE at post-assessment. There was no such interaction effect for HADS-A (F[3,779] = 2.12, p = .10). Generalized linear modeling showed no moderation of effects by baseline symptom severity.
Participants randomized to Internet-delivered CBT-I showed stable depression and anxiety across time, while control participants' depressive symptoms briefly increased. CBT-I may help prevent development or worsening of psychological distress among older adults with insomnia.

The chronic myeloid leukemia (CML) treatment success story is incomplete as some patients still fail therapy, leading to end-stage disease and death. Here we discuss recent research into CML incidence, the role of comorbidities on survival and detecting patients at risk of failing therapy.
The incidence of CML has fallen markedly in high social-demographic index (SDI) regions of the world but there is disturbing evidence that this is not the case in low and low-middle SDI countries. Now that CML patients more frequently die from their co-morbid conditions than from CML the Adult Comorbidity Evaluation-27 score can assist in risk assessment at diagnosis. Non-adherence to therapy contributes greatly to treatment failure. A good doctor-patient relationship and social support promote good adherence, but patient age, gender, and financial burden have negative effects, suggesting avenues for intervention. Mutations in cancer-associated genes adversely affect outcome and their detection at diagnosis may guide therapeutic choice and offer non-BCRABL1 targeted therapies.
