No consensus exists on the comparative efficacy and safety of sutured scleral-fixated (SSF) and anterior chamber (AC) intraocular lens (IOL) implantation. We aim to compare outcomes of these two techniques.
A systematic literature search of MEDLINE, Embase, and Cochrane CENTRAL was conducted (2005 to 2020). Studies comparing SSFIOLs with ACIOLs were included. Outcomes included corrected distance visual acuity and complications. A meta-analysis was conducted with a random effects model. Weighted mean differences and risk ratios with 95% CIs were computed.
Seven hundred eighty-three eyes from nine studies were included. SSFIOLs had a significantly higher absolute postoperative spherical equivalent (weighted mean difference, 0.32; 95% CI, 0.03 to 0.60;
= .03; low certainty) and incidence of IOL decentration/subluxation (risk ratio, 2.69; 95% CI, 1.03 to 7.01;
= .04; moderate certainty) than ACIOLs. There was no difference in final corrected distance visual acuity (
= .26).
SSFIOLs have a higher absolute postoperative spherical equivalent and incidence of IOL decentration/subluxation than ACIOLs. Future prospective studies are needed to confirm these findings.

"Referral warranted" eye disease is present at birth in about 5.5% of term infants, with "macular hemorrhage impinging on the fovea" representing about 50% of referral warranted disease. The Association of Pediatric Retina Surgeons held a symposium on February 9, 2021 that culminated in a position statement on "referable macular hemorrhage" (RMH) in newborn infants. RMH is meaningful in that in can cause amblyopia through deprivation, can be readily captured with wide-angle photography in a safe and efficient manner, and may lead to early intervention with mitigation of vision loss.

Rather than one disease, breast cancer is a heterogeneous group of diseases that express distinct molecular profiles. Neoadjuvant chemotherapy is an important therapeutic strategy for breast cancer patients independently of their molecular subtype, with the drawback of resistance development. In addition, chemotherapy has adverse effects that combined with resistance could contribute to lower overall survival. Although great efforts have been made to find diagnostic and prognostic biomarkers for breast cancer and for response to targeted and immune therapy for this pathology, little has been explored regarding biomarkers of response to anthracyclines and taxanes based neoadjuvant chemotherapy. This work aimed to evaluate the molecular profile of patients who received neoadjuvant chemotherapy to identify differentially expressed genes (DEGs) that could be used as biomarkers of chemotherapy response and overall survh lower overall survival.Case report of a unicorn anomalous double ostium left main coronary artery with common intra-mural connection. Three-dimensional virtual endo-luminal angioscopy and catheter-based imaging confirmed the diagnosis, subsequently avoiding cardiac surgical intervention.The recurrence of venous ulcers is the wound reopening after a period of completed epithelisation of a previous ulcer due to exposure to causal factors and lack of prevention. Venous ulcers have a high recurrence rate that may increase through the years. Epidemiological evidence on its incidence and risk factors is scarce due to the lack of patient follow-up in outpatient clinics and adherence to treatment after healing. The objective was to analyze the incidence of venous ulcers recurrency in outpatients and the risk factors for its occurrence. It is an observational historical cohort with retrospective data collection, performed through electronic medical records. Setting private health insurance outpatient clinic. The participants were adult patients with healed venous ulcers. Incidence of venous ulcer recurrence was calculated within individuals with healed ulcers from 2014 and 2018 with a follow-up of at least one year. Bivariate analysis and logistic regression were used to explore risk factors considering demographic, clinical, and wound-related variables. As a result, sixty-five (65) of the 134 patients with healed venous ulcers had a recurrence, leading to an incidence of 48.5%, with a mean onset time of 230.1 (SD 267) days. Patients with recurrent venous ulcers were primarily women (39/48.1%), with a mean age of 64 (SD 15.5) years, 57 (50.8%) had some comorbidity, with systemic arterial hypertension as the most frequent (47/51%). Obesity (15/88.2%) increased the risk of venous ulcers recurrence by 8.7 (OR 95% CI 2.1-60.8; P = .009) times. In conclusion, venous ulcers recurrence incidence was 48.5%, with obesity as a risk factor. This study demonstrates that the clinical approach of people with venous ulcers should not finish when the wound is healed. For ulcer recurrence prevention interventions addressing systemic factors, besides topical management of the wound, are essential.
This paper assessed the association between operative approach and postoperative in-hospital mortality in elderly patients undergoing emergency abdominal surgery. Patients undergoing emergency laparotomy have high morbidity and mortality rates. One-third of patients requiring emergency surgery are over 75 years old, and their in-hospital mortality rate exceeds 17%. Fewer than 20% of emergency abdominal operations in the UK are attempted laparoscopically, and only 10% are completed laparoscopically. Little is known about how laparoscopic emergency surgery in the elderly might affect outcomes.
An observational UK study was performed using the prospectively maintained National Emergency Laparotomy Audit (NELA) database. Operative approach, NELA risk-prediction score and in-hospital mortality were recorded. The effect of operative approach on in-hospital mortality was analysed, both on a national basis and in a high-volume laparoscopic centre.
A total of 47,667 patients were included in the study, of whom 15,068 were over 75 years of age. Nationally, surgery was completed by the laparoscopic approach in 7.8% of patients aged over 75; both crude mortality (9.2%) and risk-adjusted mortality (7.1%) were significantly reduced (
<0.0001). In our unit, surgery was completed laparoscopically in 48.4% of patients aged over 75; both crude mortality (6.6%) and risk-adjusted mortality (3.3%) were significantly reduced (
<0.0001).
Laparoscopy in emergency surgery has been shown in this study to significantly reduce in-hospital mortality in elderly patients and should be embraced in every centre dealing with emergency abdominal surgery.

To investigate the dynamic variation of D-dimer and to evaluate the efficacy and accuracy of D-dimer level in patients with thoracolumbar fractures caused by high-energy injuries.
A total of 121 patients with thoracolumbar fractures caused by high-energy injuries were retrospectively identified and included in this study. There were 83 males and 38 females, with an average age of 48.6 ± 11.2 years. All patients were treated with either screw fixation surgery or decompression fixation surgery. The D-dimer levels were measured 1 day before surgery and on the first, third, and fifth days after surgery. The dynamic variation of D-dimer and the effects of risk factors on D-dimer levels were analysed. G Protein inhibitor A receiver operating characteristic (ROC) curve analysis was performed and the appropriate D-dimer cut-off level was determined for deep vein thrombosis (DVT) screening.
Due to a trough on the third day, D-dimer levels grew in an unsustainable manner following surgery (P < 0.001). Patients with the operation g DVT diagnoses, the diagnostic value of D-dimer was highest on the third day postoperatively, and stratified cut-off values by these two factors did not show better diagnostic efficacy compared with a collective one.Hydrogen chloride (HCl) monitoring during combustion/gasification of biomass fuels and municipal solid waste, such as polyvinyl chloride (PVC) and food residues, is demanded to avoid the adverse effect of HCl to furnace operation and to improve the quality of the gas products. Infrared tunable diode laser absorption spectroscopy (IR-TDLAS) is a feasible nonintrusive in-situ method for HCl measurements in harsh environments. In the present work, the measurement was performed using the R(3) line of the ν2 vibrational band of HCl at 5739.25 cm-1 (1742.4 nm). Water vapor is ubiquitous in combustion/gasification environments, and its spectral interference is one of the most common challenges for IR-TDLAS. Spectral analysis based on the current well-known databases was found to be insufficient to achieve an accurate measurement. The lack of accurate temperature-dependent water spectra can introduce thousands parts per million (ppm) HCl overestimation. For the first time, accurate spectroscopic data of temperature-dependent water spectra near 5739.3 cm-1 were obtained based on a systematic experimental investigation of the hot water lines in a well-controlled, hot flue gas with a temperature varying from 1100 to 1950 K. With the accurate knowledge of hot water interference, the HCl TDLAS system can achieve a detection limit of about 100 ppm⋅m at around 1500 K, and simultaneously the gas temperature can be derived. The technique was applied to measure the temporally resolved HCl release and local temperature over burning PVC particles in hot flue gas at 1790 K.The transmission pathways of dengue virus (DENV) among mosquitoes are a topic that has gained relevance in recent years because they could explain the maintenance of the virus in the wild independently of the human-mosquito horizontal transmission cycle. In this regard, Aedes aegypti larvae exposed to supernatants of C6/36 cells infected with DENV-4 were evaluated for virus excretion in feces and viability of infection in immature stages (larvae). The results demonstrate that larvae excrete DENV-4 in their feces with the potential to at least infect immature individuals of the same species. A horizontal transmission pathway of larvae-larvae DENV-4 under laboratory conditions is suggested.
