Only once small effects are accepted as the norm, rather than the exception, can a reliable and reproducible cumulative psychological science be built.Purpose To report the clinical course and vascular endothelial growth factor (VEGF) levels in breast milk among three nursing women diagnosed with idiopathic choroidal neovascularization (CNV) before and after intravitreal injection of conbercept. Methods This was an observational case series. The main outcomes and measures included best-corrected visual acuity (BCVA), anatomical features using optical coherence tomography, and breast milk concentrations of VEGF before and after the intravitreal injection of conbercept. Results BCVA was increased, and no ocular or systemic safety problems were observed in any of the three patients during the follow-up period. An enzyme-linked immunosorbent assay was used to measure VEGF concentrations in the breast milk samples. Samples were collected 1 day before and 1, 7, and 30 days after the first intravitreal injection of conbercept. After conbercept injection, VEGF levels in breast milk were slightly decreased and did not change significantly in the following week; levels recovered fully by 30 days post-treatment. Conclusions Intravitreal injection of conbercept shows favorable effectiveness and safety in the treatment of idiopathic CNV in nursing women and does not result in a significant reduction in VEGF in human breast milk.

This review summarized prophylactic retinectomy technique and its effect on anatomic and functional outcomes in severe open globe injuries (OGIs).

A comprehensive search in PubMed (MEDLINE), Embase, Scopus, and EuropePMC databases was performed up until 8 January 2020. Enrolled studies include case series, studies involving pars plana vitrectomy (PPV) combined with retinectomy in severe penetrating injuries with or without IOFB, perforating injuries, and globe ruptures. Primary outcome was best-corrected visual acuity (BCVA) ⩾20/200 at the end of the study. Secondary outcomes were the rate of proliferative retinopathy (PVR), globe survival rate and retinal reattachment rate.

A total of seven studies, involving 275 eyes with severe OGIs, is included in this study. Meta-analysis indicates that final BCVA ⩾20/200 was achieved in 61% (95% CI 49%-73%). Meta-regression analysis showed that improvement was inversely affected by the presence of pre-operative direct macular injury (

 = 0.001) and corneal scar (

 = 0.015). The proportion of pre-operative BCVA <20/200 was statistically insignificant to the final BCVA ⩾20/200 (

 = 0.569). One study showed that the rate is higher in the retinectomy group than the non-retinectomy group (54% vs 11%). Meta-analysis showed that anatomical success can be achieved in 85% (95% CI 78%-91%) of the patients. Meta-regression analysis indicates that the anatomical success did not vary with age (

 = 0.653), retinal detachment (

 = 0.525), corneal scar (

 = 0.596), and lens involvement (

 = 0.450).

Early PPV combined with retinectomy was associated with acceptable visual improvement and anatomical success.

No biomaterial allowing local drug delivery has been specifically developed. However, a biocompatible bioactive implantable material could prevent some amputations, and the local release of an antitumor agent could limit risks of relapse and metastasis. Methods We propose a proof of concept of a self-setting paste combining amorphous calcium phosphate and doxorubicin-loaded particles of bone-like carbonated nanocrystalline apatite, as a means of local release. Results The cement formulation and doping, first with folic acid and then with doxorubicin, was successful. Its physicochemistry was scrutinized. Preliminary in vivo data on an invasive osteosarcoma rat model suggest a limiting effect on metastatic events in the lungs without signs of toxicity.Amid rising interest in participatory research, some industries have recently begun to practice public relations citizen science (PRCS). Unlike citizen science and crowdsourcing projects that generate raw materials for product development, PRCS benefits capitalist firms primarily by improving their public image and deflecting accusations of causing harm. Three cases illustrate how PRCS works (1) a growing assortment of citizen science projects associated with Antarctic tourism, (2) an initiative to document biodiversity, linked to Canada's oil and gas industry, and (3) a study sponsored by Biology Fortified, a nonprofit organization that works to communicate positive information about agricultural biotechnology. Scientists and research organizations may have legitimate reasons for entering into these partnerships, but PRCS can benefit industries in problematic ways. First, by supporting environmental science, PRCS can attach a 'sustainable' image to a polluting industry, without changing its core practices. Second, PRCS can accumulate data and steer volunteers' observations in ways that undermine claims about the harms caused by the industry's practices or products. Finally, in some cases, PRCS organizers hope to induce people to view an industry more 'rationally' than those who make 'emotional' or 'ideological' claims about its harms.Guidelines for vascular access recommend that the distal autogenous arteriovenous fistula (AVF) should be the first choice-access procedure for patients starting dialysis. Arteriosclerosis of radial artery may cause early failure, as well as failure of maturation of distal arteriovenous fistulas. To increase the incidence of distal AVFs, our team, specialized in vascular access surgery from 2004 onwards, has introduced Intraoperative Transluminal Angioplasty (ITA) under ultrasound (UG) or fluoroscopic guidance, to recruit inadequate arterials for creating distal fistulas. Intravascular lithotripsy (IL) is a novel approach to treat luminal and medial calcifications in patients with peripheral arterial disease and coronary disease. We believe that intraoperative IL may be an opportunity to recruit calcified radial arteries for creating distal radio-cephalic fistulas. Purpose of this study is to describe the intraoperative IL technical applied in our clinical experience. A 37-year-old diabetic patient with distal radio-cephalic fistula was recruited for the first IL experience. One year ago, a wrist radio-cephalic fistula was created in the right upper limb, with intraoperative UG radial artery angioplasty for extensive calcifications. The fistula was functioning but showed a delay in maturation. An angioplasty was unsuccessfully attempted to facilitate the maturation. Subsequently, a surgical revision of the fistula was performed, creating a new anastomosis immediately upstream of the previous one by performing an intraoperative IL UG of the radial artery. The fistula was immediately well functioning, and was cannulated with two needles after 1 month. It is currently being used with intradialytic adequate blood flow. The positive outcome of the case described in this paper, even if only anecdotal, could act as a trigger for further experiences with IL.Purpose To determine whether MRI volumetric and image texture analysis correlates with treatment-induced biologic changes in desmoid fibromatosis (DF) earlier than conventional response criteria. Materials and Methods This retrospective study included 27 patients with histologically proven extra-abdominal DF who were managed with active surveillance or systemic therapy (from 2004 to 2016). MRI volumetric and image texture parameters were derived from manual tumor segmentations, and tumor signal intensity was normalized to muscle. Results were compared with objective response rates based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, World Health Organization (WHO) lesion response, volumetrics, and MRI-modified Choi criteria. Correlation coefficients (r) between image texture features and maximum tumor diameters were obtained by using a meta-analysis approach. Results The 27 included patients (mean age, 39 years; 74% women) were followed for an average of 4 years, comprising 207 distinct time-point assessments. The mean baseline tumor maximum diameter was 7.9 cm (range, 3.4-15.2 cm). Partial response (PR) rates as best response were 37%, 44%, 70%, and 81% by RECIST, WHO, volumetrics, and MRI-modified Choi criteria, respectively. Among the 10 tumors showing RECIST PR, a preceding MRI-modified Choi PR was observed in 70% (seven of 10), on average 1.3 years earlier. Multiple image texture parameters showed associations with objective measurements of tumor diameter including mean tumor-to-muscle signal ratio (r = 0.51; P = .004), median tumor-to-muscle signal ratio (r = 0.52; P = .003), energy (r = 0.48; P less then .001), run entropy (r = 0.32, P = .04), and gray-level nonuniformity (r = 0.54; P ≤ .001). Conclusion Volumetric signal and image texture assessment allows more comprehensive analysis of DF biologic change and may permit early prediction of DF behavior and therapeutic response.

To study the correlation between the mean arterial pressure (MAP) level in the first 6 hours of extracorporeal cardiopulmonary resuscitation (ECPR) and patients' neurological outcomes.

Sex, age, basic comorbidities, the time from the first cardiac arrest to the start of CPR, the time from the first cardiac arrest to extracorporeal membrane oxygenation (ECMO), standardized ECMO flow, and the pH value at the beginning of ECMO and after 6 hours were recorded. MAP was recorded every 2 hours during the first 6 hours, and the average was calculated. The lactic acid clearance rate of the first 6 hours was calculated. Evaluated the neurological prognosis of patients at discharge. Then the patients were divided into groups according to their average MAP, and the above variables were compared in groups.

Enrolled 63 adult ECPR patients. There were no statistically significant differences in sex, age, basic comorbidities, the time from the first cardiac arrest to the start of conventional CPR, the time from the firent remains to be further studied.

Numerous studies have reported the incidence and outcomes of injuries in the men's and women's National Basketball Association (NBA and WNBA, respectively).

To synthesize published data regarding the incidence and outcomes of all injuries in the NBA and WNBA in a comprehensive review.

Systematic review; Level of evidence, 4.

Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched 3 electronic databases (PubMed, MEDLINE, Embase) for studies of all levels of evidence since 1990 pertaining to injuries sustained by active players in the NBA and WNBA. Studies were excluded if the cohort of interest included ≤3 active players.

The initial search of the 3 databases yielded 1253 unique studies, of which 49 met final inclusion criteria for this review. Only 4 studies included athletes in the WNBA. Based on the mean annual incidence, the 5 most common orthopaedic sports injuries sustained in the NBA were concussions (9.5-14.9 per year), fractures of the hand (3.
