ABSTRACT

PURPOSE: The short- and long-term andrological effects of coronavirus disease 2019 (COVID-19) have not been clarified. Our aim is to evaluate the available evidence regarding possible andrological consequences of COVID-19 either on seminal or hormonal parameters. The safety of the COVID-19 vaccines in terms of sperm quality was also investigated. METHODS: All prospective and retrospective observational studies reporting information on severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) mRNA semen and male genitalia tract detection (n = 19), as well as those reporting data on semen analysis (n = 5) and hormonal parameters (n = 11) in infected/recovered patients without any arbitrary restriction were included. RESULTS: Out of 204 retrieved articles, 35 were considered, including 2092 patients and 1138 controls with a mean age of 44.1 ± 12.6 years, and mean follow-up 24.3 ± 18.9 days. SARS-CoV-2 mRNA can be localized in male genitalia tracts during the acute phase of the disease. COVID-19 can result in short-term impaired sperm and T production. Available data cannot clarify long-term andrological effects. Low T observed in the acute phase of the disease is associated with an increased risk of being admitted to the Intensive Care Unit or death. The two available studies showed that the use of mRNA COVID-19 vaccines does not affect sperm quality. CONCLUSIONS: The results of our analysis clearly suggest that each patient recovering from COVID-19 should be monitored to rule out sperm and T abnormalities. The specific contribution of reduced T levels during the acute phase of the infection needs to be better clarified.

ABSTRACT

PURPOSE: To evaluate the effect of internal limiting membrane (ILM) peeling during vitrectomy for nontractional diabetic macular edema. METHODS: PUBMED, MEDLINE and CENTRAL were reviewed using the following terms (or combination of terms): diabetic macular edema, nontractional diabetic macular edema, internal limiting membrane peeling, vitrectomy, Müller cells. Randomized and nonrandomized studies were included. The eligible studies compared anatomical and functional outcomes of vitrectomy with or without ILM peeling for tractional and nontractional diabetic macular edema. Postoperative best-corrected visual acuity and central macular thickness were considered, respectively, the primary and secondary outcomes. Meta-analysis on mean differences between vitrectomy with and without ILM peeling was performed using inverse variance method in random effects. RESULTS: Four studies with 672 patients were eligible for analysis. No significant difference was found between postoperative best-corrected visual acuity or best-corrected visual acuity change of ILM peeling group compared with nonpeeling group. There was no significant difference in postoperative central macular thickness and central macular thickness reduction between the two groups. CONCLUSIONS: The visual acuity outcomes in patients affected by nontractional diabetic macular edema using pars plana vitrectomy with ILM peeling versus no ILM peeling were not significantly different. A larger prospective and randomized study would be necessary.

ABSTRACT

Tear film is critical for the well-being and homeostasis of the ocular surface. Although the composition of the tear film is well known, the composition of metallic elements have yet to be analysed. Despite trace elements metabolism has been reported to play a role in the pathogenesis of diabetes mellitus, a metabolic disease that affects several aspects of homeostasis, little is known in the literature regarding concentration and possible variation of metallic elements in tear film. We studied the concentrations of several essential and non-essential metallic elements in the tear fluid and serum of patients with type II diabetes mellitus and a group of non-diabetic controls. Serum and tear fluid were collected from 97 patients: 47 type II diabetic patients and 50 non-diabetic controls. Regarding tear film, there were statistically significant differences in Zinc, Chrome, Cobalt, Manganese, Barium, and Lead between groups; the values of all metallic elements were found to be statistically significant higher in patients with mellitus type II diabetes. Regarding serum values there was a statistically significant difference in Chrome, Cobalt, and Selenium values; the concentrations of Chrome and Cobalt were higher in the control group, while Selenium concentration was higher in diabetic patients. In patients with type II diabetes, metal elements with higher concentrations in tears compared to serum were: Lead, Barium, Manganese, Cobalt, and Chrome. In the control group, the metal elements with the highest concentration in tear film compared to serum were Chrome, Manganese, Barium, and Lead. In this study, we attempted to evaluate the possible effect of a disease, such as diabetes, on the metabolism of metallic elements. Although our evidence was very interesting, it is probably limited in its accuracy due to the fact that individuals in the control group harboured ocular pathologies. This work lays the foundation for future studies.

ABSTRACT

We report the case of a patient with hereditary ceruloplasmin deficiency due to a novel gene mutation in ceruloplasmin gene (CP), treated with fresh frozen plasma (FFP) and iron chelation therapy. A 59-year-old man with a past history of diabetes was admitted to our department due to progressive gait difficulties and cognitive impairment. Neurological examination revealed a moderate cognitive decline, with mild extrapyramidal symptoms, ataxia, and myoclonus. Brain T2-weighted MR imaging showed bilateral basal ganglia hypointensity with diffuse iron deposition. Increased serum ferritin, low serum copper concentration, undetectable ceruloplasmin, and normal urinary copper excretion were found. The genetic analysis of the CP (OMIM #604290) reported compound heterozygosity for two mutations, namely c.848G > A and c.2689_2690delCT. Treatment with FFP (500 mL i.v./once a week) and administration of iron chelator (Deferoxamine 1000 mg i.v/die for 5 days, followed by Deferiprone 500 mg/die per os) were undertaken. At the 6-month follow-up, clinical improvement of gait instability, trunk ataxia, and myoclonus was observed; brain MRI scan showed no further progression of basal ganglia T2 hypointensity. This case report suggests that the early initiation of combined treatment with FFP and iron chelation may be useful to reduce the accumulation of iron in the central nervous system and to improve the neurological symptoms.

ABSTRACT

BACKGROUND: To demonstrate the efficacy of intravitreal ranibizumab (IVR) in combination with reduced-fluence photodynamic therapy (RF-PDT) in patients with choroidal neovascularization (CNV) secondary to pathologic myopia. METHODS: Sixty patients affected by myopic CNV (mCNV) were randomized to receive either ranibizumab 0.5 mg monotherapy (RM; n = 20), standard fluence PDT (SF-PDT, n = 20) or RF-PDT combination therapy (n = 20). Subsequently, IVR was injected as needed. All patients were evaluated for 48 weeks. RESULTS: Mean BCVA change at 48 weeks was + 0.2 and +15 letters with SF or RFPDT plus ranibizumab, respectively, compared with +16.8 letters with RM. At 48 weeks, mean central foveal thickness (CFT) decrease from baseline was 58 ± 15 µm, 91.4 ± 43.8 µm, and 85 ± 41.5 µm for the verteporfin SF, RF and RM groups, respectively. Macular sensitivity improvement was + 0.4 db, + 1.9 dB and + 2.7 dB for the verteporfin SF, RF and RM groups, respectively. CONCLUSIONS: Ranibizumab monotherapy or combined with RF-PDT improved BCVA and macular sensitivity in patients affected by mCNV, whereas CFT results were reduced. SF-PDT combination regimen mostly stabilized vision at 48 weeks. Among all groups, the RF-PDT seemed to reduce the number of ranibizumab retreatments.

ABSTRACT

BACKGROUND: Even in western developed countries, the probability of survival after out-of-hospital cardiac arrest (OHCA) is only 6-10%. In order to improve survival after OHCA, early initiation of cardiopulmonary resuscitation (CPR) by laypersons is essential. Introduction of CPR training in schoolchildren seems to be effective to increase lay-CPR rates. OBJECTIVE: The objective of the present investigation was to elucidate educational aspects of teaching schoolchildren in CPR and to summarize campaigns related to a comprehensive establishment of lay-CPR worldwide. MATERIALS AND METHODS: A literature research in PubMed was performed, the cutoff date was 27 February 2017. Overall, 192 abstracts were analyzed; 51 articles were considered relevant and included in the manuscript. An additional keyword research in Google revealed >230,000 entries, and 20 of those were included in the present manuscript. RESULTS: A minimum age of 12-13 years is required to achieve a comparable quality of CPR to adult basic life support (BLS). Key issues are (i) the correct detection of a cardiac arrest, (ii) a correctly performed call for help, (iii) thoracic compressions and (iv) if applicable, the initiation of adequate mouth-to-mouth ventilation. Practical training showed a significantly higher CPR quality compared to theoretical training only or to the use of instruction or online videos only. Worldwide implementation of a 2-h BLS training per year in children from the age of 12 or younger is recommended by the "Kids Save Lives"- statement since 2015. In Germany, implementation at the level of the federal states has progressed to different degrees.

ABSTRACT

AIM: The aim of this study was to evaluate concentrations of erythropoietin (EPO) and vascular endothelial growth factor (VEGF) in serum, aqueous and vitreous humour of diabetic patients with proliferative retinopathy (PDR) and to verify their possible modifications induced by intravitreal injection of bevacizumab (IVB). METHODS: This prospective observational study was performed on patients who underwent vitrectomy for proliferative diabetic retinopathy and macular hole or pucker. The study sample consisted of 33 patients with proliferative diabetic retinopathy and 20 non-diabetic patients with macular hole or pucker. EPO and VEGF levels in serum, aqueous and vitreous humour were measured in both groups. In diabetic patients measures were performed before and after IVB. RESULTS: EPO and VEGF levels in aqueous and vitreous humour were markedly increased in diabetic patients with PDR as compared with those recorded in the control group (P<0.001); contrarily, EPO serum levels were similar in both groups (p=not significant). IVB did not affect EPO levels (aqueous 39.1 ± 29.2 vs. 38.6 ± 26.1; vitreous 179.3 ± 88.3 vs. 131.6 ± 67.8; serum 9.2 ± 5.8 vs. 6.9 ± 3.7 mUI/mL); conversely, VEGF concentration significantly decreased 15 days after IVB in serum and ocular fluids (aqueous 141.6 ± 12.3 vs. 81.4 ± 5.4; vitreous 180.4 ± 45.8 vs. 95.8 ± 23.6; serum 113.9 ± 52.8 vs. 73.2 ± 65.6 mUI/mL). CONCLUSION: These findings demonstrate that the production of VEGF and EPO is regulated by different mechanisms. Intraocular levels of EPO in diabetic patients were significantly higher than those recorded in serum, suggesting a local production. In addition, bevacizumab does not influence intraocular levels of EPO.

ABSTRACT

Frontotemporal dementia (FTD) is one of the most important neurodegenerative conditions and Granulin (GRN) is one of the major genes associated to the disease. FTD-GRN patients are still orphan for any evidence-based target-therapy approach. Interestingly, it has been recently found that alkalizing agents rescued haploinsufficiency in cellular models expressing FTD-GRN mutations. We set up a pilot phase II clinical trial in five FTD patients with GRN Thr272s(g.1977_1980delCACT) mutation, to determine if amiodarone (200 mg/day) may (1) reverse progranulin deficiency and (2) delay disease progression. Each patient was scheduled for 7 study visits over 12 months period. We assessed GRN levels at baseline and after amiodarone administration during the treatment course. Somatic and neurologic examinations, along with cognitive and behavioral assessment were recorded as well. No significant effect on peripheral GRN levels was observed. In treated FTD, disease course did not differ when compared with a group of untreated FTD-GRN patients. This is the first trial targeting progranulin rescue in FTD-GRN patients using amiodarone. Despite the negative findings, it may be interesting to extend this attempt to a larger sample of subjects and to other alkalizing agents to restore granulin haploinsufficiency.

ABSTRACT

Neurotrophic keratitis (NK) is a rare degenerative corneal disease that occurs as a result of partial or total impairment of trigeminal innervations, leading to a reduction (hypoesthesia) in or loss (anaesthesia) of corneal sensitivity. The impairment of sensory innervation causes a reduction in the lacrimation reflex and the vitality, metabolism and mitosis of epithelial cells, with subsequent deficiency in epithelial repair, stromal and intracellular oedema, loss of microvilli, and abnormal development of the basal lamina. Several recent studies have proposed different therapies based on different aetiopathogenetic theories. The aim of the therapy is to treat aetiopathogenesis and, at the same time, promote corneal healing. In this paper, we report the aetiology, diagnosis, management, and medical and surgical treatment of NK, also indicating future treatments based on the most recent studies.

ABSTRACT

Standardized reporting of data is crucial for out-of-hospital cardiac arrest (OHCA) research. While the implementation of first responder systems dispatching volunteers to OHCA is encouraged, there is currently no uniform reporting standard for describing these systems. A steering committee established a literature search to identify experts in smartphone alerting systems. These international experts were invited to a conference held in Hinterzarten, Germany, with 40 researchers from 13 countries in attendance. Prior to the conference, participants submitted proposals for parameters to be included in the reporting standard. The conference comprised five workshops covering different aspects of smartphone alerting systems. Proposed parameters were discussed, clarified, and consensus was achieved using the Nominal Group Technique. Participants voted in a modified Delphi approach on including each category as a core or supplementary element in the reporting standard. Results were presented, and a writing group developed definitions for all categories and items, which were sent to participants for revision and final voting using LimeSurvey web-based software. The resulting reporting standard consists of 68 core items and 21 supplementary items grouped into five topics (first responder system, first responder network, technology/algorithm/strategies, reporting data, and automated external defibrillators (AED)). This proposed reporting standard generated by an expert opinion group fills the gap in describing first responder systems. Its adoption in future research will facilitate comparison of systems and research outcomes, enhancing the transfer of scientific findings to clinical practice.

ABSTRACT

The aim of the study is to evaluate the effectiveness and safety of intravitreal infliximab in the course of compassionate use in patients affected by choroidal neovascularization. This prospective interventional case series includes four eligible patients, affected by exudative age-related macular degeneration (2/4), retinal angiomatous proliferation (1/4) and central retinal vein occlusion (1/4), who were refractory to conventional treatments. The patients received a single intravitreal injection of 0.05 ml of reconstituted infliximab solution (20mg/ml). The main outcomes measure were changes in best-corrected visual acuity and central retinal thickness. Patients were evaluated at baseline, every week for the first month, then every two weeks, and on demand. Morphologic parameters improved after a single infliximab intravitreal injection. However, all patients developed acute uveitis in a period ranging from 4 to 7 weeks after treatment. Control of the intraocular inflammation was achieved with topical and systemic steroids in 3 patients, whereas in one case pars plana vitrectomy was needed. A single intravitreal injection of infliximab does not seem to improve the natural history of CNV from different aetiologies. However, all patients in our series developed a serious inflammatory response that required surgical management in one case. The intravitreal administration of infliximab is hence not safe and not recommended in clinical practice.

ABSTRACT

We assess the level of tumour necrosis factor alpha (TNF-alpha) in tear fluids and other serum parameters associated with diabetes in different degrees of diabetic retinopathy. We have performed a prospective, nonrandomized, observational study. Study population consisted of 16 healthy subjects (controls) and 32 type 2 diabetic patients: 16 affected by proliferative diabetic retinopathy (PDR) and 16 with nonproliferative retinopathy (NDPR, background/preproliferative). Body mass index, urinary albumin, blood glucose, HbA1c, and tear levels of TNF-alpha were measured in all subjects. The value of glycaemia, microalbuminurea, and Body mass index in diabetic retinopathy groups were higher than those in control group (P < 0.05). Glycemia in NPDR: 6.6 mmol/L (range: 5.8-6.3); in PDR: 6.7 mmol/L (range: 6.1-7.2); in control: 5.7 mmol/L (range: 4.9-6.1); microalbuminurea in NPDR: 10.6 mg/L (range: 5.6-20); in PDR: 25.2 mg/L (range: 17-40); in control: 5.3 mg/L (range: 2.6-10); Body mass index in NPDR: 26 Kg/m(2) (range: 20.3-40); in PDR: 28 Kg/m(2) (range 20.3-52); in control: 21 Kg/m(2) (range 19-26). The TNF-alpha concentrations in tears increase with the severity of pathology and were lower in control group than in diabetic subjects. In the end, the level of TNF-alpha is highly correlated with severity of diabetic retinopathy and with nephropathy. Tear fluid collection may be a useful noninvasive method for the detection of proliferative diabetic retinopathy.

ABSTRACT

BACKGROUND: Ocular trauma is a major cause of monocular blindness and visual impairment in industrialized countries. OBJECTIVES: The aim of this paper was to study epidemiology, causes, and clinical features of work-related and non-work-related eye injuries in a highly industrialized area of northern Italy. METHODS: All patients hospitalized for eye injuries were enrolled. Two 3-year periods were studied (1994-1996 and 2005-2007). The variables analyzed included sex, age, social class of the patients, nature of the injuring agent (e.g., metal, plastic, etc.), place where the accident occurred (e.g., home, work, etc.), and time of the year (e.g., summer, winter, etc.). RESULTS: We enrolled 1001 men and 129 women. There were no significant differences between the two 3-year periods as regards distribution of sex, age, and location. Road-related injuries significantly decreased (p < 0.004). Comparison of injuring agents showed a decrease in metallic agents (p < 0.001) and an increase in lime agents (p < 0.001). Analysis of the type of trauma showed a decrease in blunt traumas (p < 0.001) and an increase in chemical injuries (p < 0.001) and actinic keratitis (p = 0.002). In the second 3-year period, we found a significant increase in injuries in non-Italian subjects (p < 0.001). CONCLUSIONS: Work-related injuries were the major cause of eye trauma. Road accident-related eye injuries dropped significantly in the second 3-year period. The adoption of higher safety standards, as well as information and educational campaigns, can significantly reduce work-related and non-work-related eye injuries.

ABSTRACT

The study has been performed on tears of apparently healthy subjects who live and work in urban and rural areas, respectively. After the collection the following elements were investigated: chromium (Cr); arsenic (As); copper (Cu); zinc (Zn); selenium (Se); rubidium (Rb); barium (Ba); lead (Pb) and cobalt (Co). Significantly higher values of As were found in subjects living and working in rural areas as compared to those found in urban area residents (0.290 vs. 0.025; p<0.001). Conversely, Ba and Pb were significantly lower in rural area residents (1.10 vs. 2.50, p=0.027 and 1.70 vs. 1.10, p=0.057, respectively). Our data show that trace elements analysis in tears is possible; further studies could define if it could be a reliable biomarker in persons exposed to high concentration of trace elements due to working or environmental reasons.

ABSTRACT

We present a retrospective series of 11 patients treated for isolated sphenoid inflammatory disease (ISID) with visual impairment in the period between 1994 and 2008. The series included 7 females and 4 males. All patients, preoperatively assessed by CT or MR, underwent endoscopic sinus surgery and broad-spectrum antibiotic therapy. The procedure was always performed in an emergency setting, with an interval from the onset of visual impairment ranging between 1 and 40 days (mean 9 days). The possibility of recovery was related to both the modality of onset and severity of the deficit. All patients with reduction of the visual field reported significant improvement after surgery. Patients with decreased visual acuity obtained partial or complete resolution, while in patients with preoperative blindness no improvement was observed. Moreover, no postoperative improvement was noticed in the case of severe deficits with sudden onset, whereas the treatment of mild deficits was successful even some weeks after their occurrence. In conclusion, although some factors may predict the likelihood of recovery, any patient with ISID associated with visual impairment should receive immediate medical and surgical treatment. Endoscopic surgery should be considered the technique of choice.

ABSTRACT

AIM OF THE SCOPING REVIEW: Scientific recommendations on resuscitation are typically formulated from the perspective of an ideal resource environment, with little consideration of applicability in lower-income countries. We aimed to determine clinical outcomes from out-of-hospital cardiac arrest (OHCA) in low-resource countries, to identify shortcomings related to resuscitation in these areas and possible solutions, and to suggest future research priorities. DATA SOURCES: This scoping review was part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation (ILCOR), and was performed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. We identified low-resource countries as countries with a low- or middle gross national income per capita (World Bank data). We performed a literature search on outcomes after OHCA in these countries, and we extracted data on the outcome. We applied descriptive statistics and conducted a post-hoc correlation analysis of cohort size and ROSC rates. RESULTS: We defined 24 eligible studies originating from middle-income countries, but none from low-income regions, suggesting a reporting bias. The number of reported patients in these studies ranged from 54 to 3214. Utstein-style reporting was rarely used. Return of spontaneous circulation varied from 0% to 62%. Fifteen studies reported on survival to hospital discharge (between 1.0 and 16.7%) or favourable neurological outcome (between 1.0 and 9.3%). An inverse correlation was found for study cohort size and the rate of return of spontaneous circulation (ρ = -0.48, p = 0.034). CONCLUSION: Studies of OHCA outcomes in low-resource countries are heterogeneous and may be compromised by reporting bias. Minimum cardiopulmonary resuscitation standards for low-resource settings should be developed collaboratively involving local experts, respecting culture and context while balancing competing health priorities.

ABSTRACT

Coronavirus disease 2019 (COVID-19) has had a substantial impact on the incidence of cardiac arrest and survival. The challenge is to find the correct balance between the risk to the rescuer when undertaking cardiopulmonary resuscitation (CPR) on a person with possible COVID-19 and the risk to that person if CPR is delayed. These guidelines focus specifically on patients with suspected or confirmed COVID-19. The guidelines include the delivery of basic and advanced life support in adults and children and recommendations for delivering training during the pandemic. Where uncertainty exists treatment should be informed by a dynamic risk assessment which may consider current COVID-19 prevalence, the person's presentation (e.g. history of COVID-19 contact, COVID-19 symptoms), likelihood that treatment will be effective, availability of personal protective equipment (PPE) and personal risks for those providing treatment. These guidelines will be subject to evolving knowledge and experience of COVID-19. As countries are at different stages of the pandemic, there may some international variation in practice.

ABSTRACT

Diabetic retinopathy (DR) is the most common microvascular complication of diabetes and the leading cause of visual impairment in the working-age population in the Western world. Diabetic macular oedema (DME) is one of the major complications of DR. Therapy with intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) drugs has become the gold standard treatment for DR and its complications. However, these drugs have no effect on the pathogenesis of DR and must be administered frequently via invasive intravitreal injections over many years. Thus, there is a pressing need to develop new therapeutic strategies to improve the treatment of this devastating disease. Indeed, an increasing volume of data supports the role of the inflammatory process in the pathogenesis of DR itself and its complications, including both increased retinal vascular permeability and neovascularization. Inflammation may also contribute to retinal neurodegeneration. Evidence that low-grade inflammation plays a critical role in the pathogenesis of DME has opened up new pathways and targets for the development of improved treatments. Anti-inflammatory compounds such as intravitreal glucocorticoids, topical non-steroidal anti-inflammatory drugs (NSAIDs), antioxidants, inflammatory molecule inhibitors, renin-angiotensin system (RAS) blockers and natural anti-inflammatory therapies may all be considered to reduce the rate of administration of antineovascularization agents in the treatment of DR. This report describes the current state of knowledge of the potential role of anti-inflammatory drugs in controlling the onset and evolution of DR and DME.

ABSTRACT

PURPOSE: To evaluate the visual outcome of patients with subfoveal choroidal neovascularization (CNV) secondary to pathologic myopia treated with verteporfin photodynamic therapy (PDT-V) and to verify the predictive role of visual and angiographic parameters. METHODS: This is a retrospective, interventional, consecutive case series study of subjects with subfoveal CNV secondary to pathologic myopia. All patients received PDT-V according to VIP guidelines. A complete ophthalmologic evaluation was performed on all patients and included best-corrected visual acuity (BCVA), fundus examination, and fluorescein angiography (FA, IMAGEnet System, Topcon Corp., Japan). CNV size (mm2) was directly measured on the early phase of the angiogram using the software included with the IMAGEnet package. All checks were scheduled at 3-month intervals for a period of 1 year. A review of medical and angiographic records was performed and assessed throughout a 12-month follow-up period. RESULTS: A total of 62 patients (62 eyes) were examined. Best-corrected visual acuity (BCVA) moderately decreased without reaching a statistically noticeable level throughout the followup; reduction in lesion size reached a significant level at the second checkup. A significant correlation between higher baseline BCVA and better final visual outcome was detected. CONCLUSIONS: Standardized PDT-V minimizes central vision deterioration in patients with CNV secondary to pathologic myopia. Better BCVA at presentation represents a good predictive sign.
