To determine whether an automated artificial intelligence (AI) model could assess macular hole (MH) volume on swept-source optical coherence tomography (OCT) images.

This was a proof-of-concept consecutive case series. Patients with an idiopathic full-thickness MH undergoing pars plana vitrectomy surgery with 1 year of follow-up were considered for inclusion. MHs were manually graded by a vitreoretinal surgeon from preoperative OCT images to delineate MH volume. This information was used to train a fully three-dimensional convolutional neural network for automatic segmentation. The main outcome was the correlation of manual MH volume to automated volume segmentation.

The correlation between manual and automated MH volume was R

= 0.94 (

= 24). Automated MH volume demonstrated a higher correlation to change in visual acuity from preoperative to the postoperative 1-year time point compared with the minimum linear diameter (volume R

= 0.53; minimum linear diameter R

= 0.39).

MH automated volume segmentation on OCT imaging demonstrated high correlation to manual MH volume measurements.

[Ophthalmic Surg Lasers Imaging Retina. 2022;53(4)208-214.].Familial exudative vitreoretinopathy (FEVR) is a rare hereditary vitreoretinopathy resulting from mutations in the wnt signaling pathway leading to abnormalities in fetal retinal vasculogenesis, angiogenesis, and retinal vascular maintenance. this website Severe FEVR may result in congenital retinal detachment resembling Norrie disease. The authors report the first case of planned preterm delivery and treatment of a patient with severe FEVR from biallelic LRP5 mutations whose siblings had congenital tractional retinal detachments with light perception vision outcomes after conventional care. Early intervention allowed laser ablation of avascular retina and functional visual outcome despite a successfully repaired unilateral tractional retinal detachment.

To describe the anatomic and visual outcomes of eyes undergoing autologous iris transplantation for macular hole retinal detachment.

Seven consecutive patients with macular hole retinal detachment were enrolled in a single-arm prospective study. All patients underwent pars plana vitrectomy with autologous iris transplantation placed in the subretinal space as a plug to close the macular hole; in one case, a posterior retinal break was also closed with the same technique.

Seven patients (2 males and 5 females) with a mean age of 69.14 ± 7.79 years (range 58-80 years) were followed up for a period of six months. The best-corrected visual acuity improved from 2.44 ± 0.48 logMAR (20/2000) preoperatively to 1.90 ± 0.26 logMAR (20/800) 6 months after surgery. Optical coherence tomography analysis showed retinal adhesion around the iris plug, and the retina remained dry in the follow-up period.

In this series of macular hole retinal detachments, autologous iris transplantation placed as a plug over the retinal pigment epithelium facing the macular hole opening or directly over the bare sclera achieved anatomical success with improvement in visual function.

For the 30% of Australians who live in rural areas, access to rehabilitation services after sustaining a major traumatic injury can be challenging. This study aimed to explore the experience of rural major traumatic injury survivors accessing rehabilitation services.

Semi-structured interviews were conducted with 21 rural major traumatic injury survivors (

= 47.86;

 = 11.35; Range 21-61) who were an average of seven years post-injury (

 = 3.10; Range 3.25-13.01). Transcribed interviews were thematically analysed.

Four themes were identified (1)

While injury-related symptoms persisted for many participants, they expressed strong determination for independence and self-management of their recovery. Barriers to accessing rehabilitation services included poor knowledge of local services, travel burden, financial costs, and a lack of local practitioners experienced in major traumatic injury rehabilitation. Facilitating factors included financial, psychological, community, aery, future rural service models should improve consideration of factors resulting from living at a distance to services and harness independence to self-manage.IMPLICATIONS FOR REHABILITATIONRural major traumatic injury survivors need support to navigate numerous barriers to accessing rehabilitation services.Rural participants expressed their preference for greater involvement in planning their transition back home following hospitalisation and help to link with available services in their local area.Specialist training and support for rural rehabilitation practitioners is needed, to effectively treat impairments related to major traumatic injury, particularly psychological and cognitive difficulties.Future service delivery models should incorporate methods to locate rural services; facilitate telehealth access and client self-management; and provide financial and mental health support to both rural survivors of major traumatic injury and their carers.

Low food security and poor mental health are a persistent concern for college students.

Examine how food security and mental health are associated with college student's grade point average (GPA).

American College Health Association (ACHA)-National College Health Assessment III survey data Spring 2020 of students from 75 US universities (

 = 48,103) were utilized to examine relationships among mental health, food security and academic performance (GPA).

The majority of the population self-reported high food security (58.3%) and moderate psychological distress (50.8%). Very low food security (

= -.523, OR = .59,

 < .001) and moderate psychological distress (

= -0.19, OR = .83,

 < .001) were inversely associated with high GPA. Reduced food security was associated with worse mental health measures.

Food security and mental health are negatively associated with GPA. To improve student success, universities must enhance services that address food insecurity and mental health.

The current systematic review provides a perspective on the persistence of various antibodies for available vaccines.Both the BNT162b2 and the mRNA-1273 induce the production of IgA antibodies, reflecting the possible prevention of the asymptomatic spread. The mRNA-1273 vaccine's antibodies were detectable until 6 months, followed by the AZD1222, 3 months, the Ad26.COV2.S and the BNT162b2 vaccines within 2 months.The BNT162b2 produced anti-spike IgGs 11 days after the first dose and peaked at day 21, whereas the AZD1222 induced a neutralizing effect 22 days after the first dose.These vaccines induce T-cell mediated immune responses too. Each one of the AZD1222, Ad26.COV2.S, mRNA-1273 mediates T-cell response immunity at days 14-22, 15, and 43 after the first dose, respectively. Whereas for the BNT162b1 and BNT162b2 vaccines, T-cell immunity is induced 7 days and 12 weeks after the booster dose, respectively.

The World Health Organization declared vaccine hesitancy a top threat to global health following resurgence of vaccine-preventable diseases close to eradication in many countries (e.g. measles). Vaccines are effective in preventing severe illness, hospitalization, and death from COVID-19, yet there remains a small proportion of the eligible population who choose not to vaccinate. Social media and online news sources are opportunities for targeted public health interventions to improve vaccine uptake. This study reports the results of a semi-structured interview study that explored the influence of media and information on individuals' self-reported intentions to vaccinate against COVID-19.

A qualitative descriptive study was employed to gain insight from a diverse group of individuals. Adult participants were recruited through a related COVID-19 study; we used a maximum variation sampling technique and purposively sampled participants based on demographics. Interviews were conducted from February 2021 to epend upon authorities' ability to disseminate accessible, detailed, and consistent information promoting public confidence.Globally, avian colibacillosis is a leading cause of morbidity and mortality in poultry, associated with economic losses and welfare problems. Here, clinical avian pathogenic E. coli isolates (CEC; n = 50) and faecal E. coli isolates from healthy (FEC; n = 187) Australian meat chickens collected between 2006 and 2014 were subjected to antimicrobial susceptibility testing, phylogenetic grouping, plasmid replicon (PR) typing, multilocus sequence typing, and virulence gene (VG) profiling. Extended-spectrum cephalosporin (ESC)- and fluoroquinolone (FQ)-resistant E. coli isolates underwent further genetic characterization. Significant proportions of CEC and FEC were, respectively, susceptible (13/50; 48/187) or MDR (9/50; 26/187) to 20 tested antimicrobials. Phylogenetic groups A and C, and PR types IncFIB and IncFrep were most represented. Five tested CEC-associated VGs were more prevalent in CEC (≥ 90%) than FEC (≤ 58%). Some isolates (CEC n = 3; FEC n = 7) were resistant to ESCs and/or FQs and possessed signature mutations in chromosomal FQ target genes and plasmid-mediated qnrS, blaCMY-2, and blaDHA-1 genes. Sequence type 354 (n = 4), associated with extraintestinal infections in a broad range of hosts, was prevalent among ESC- and/or FQ-resistant FEC. This study confirmed existence of a small reservoir of ESC- and FQ-resistant E. coli in Australian commercial meat chickens despite absence of use in the industry of these drugs. Otherwise, diversity of VGs and PR types in both FEC and CEC populations was identified. We hypothesize that the source of ESC- and FQ-resistant E. coli is external to poultry production facilities.RESEARCH HIGHLIGHTSLow-level resistance to older and newer generation antimicrobial drugs detected.The most common sequence type (ST) associated with FQ resistance was ST354 (4/10).A small proportion of CEC (n = 3) and FEC (n = 7) were resistant to ESCs and/or FQs.Thioureas and their derivatives are organosulfur compounds having excellent biological and non-biological applications. These compounds contain S- and N-, which are nucleophilic and allow for establishing inter-and intramolecular hydrogen bonding. These characteristics make thiourea moiety a very important chemosensor to detect various environmental pollutants. This article covers a broad range of thioureas and their derivatives that are used for highly sensitive, selective, and simple fluorimetric (turn-off and turn-on), and colorimetric chemosensors for the detection and determination of different types of anions, such as CN-, AcO-, F-, ClO- and citrate ions, etc., and neutral analytes such as ATP, DCP, and Amlodipine, etc., in biological, environmental, and agriculture samples. Further, the sensing performances of thioureas-based chemosensors have been compared and discussed, which could help the readers for the future design of organic fluorescent and colorimetric sensors to detect anions and neutral analytes.
