Cilj rada je prikazati incidenciju okluzije središnje mrežnične vene i ogranaka u Dubrovačko-neretvanskoj županiji u razdoblju od 1.1.2010. do 31.12.2014. godine. Metode: Retrospektivna analiza ...podataka po spolu, dobi, vrsti okluzije, vidnoj oštrini prije i poslije terapije i komorbitetima iz dokumentacije retinološke ambulante Odjela za oftalmologiju Opće bolnice Dubrovnik. Rezultati: U razdoblju od 1.1.2010. do 31.12. 2014. god. u retinološkoj ambulanti Opće bolnice Dubrovnik dijagnoza okluzije središnje mrežnične vene i ogranka postavljena je na 48 očiju, u 47 pacijenata. Jedna pacijentica imala je bilateralnu okluziju mrežnične vene. Žena je bilo 62,5 %. Ukupna srednja dob svih oboljelih bila je 68,79 godina. Žene su u prosjeku bile nešto starije i prosječna dob im je bila 69,33 godine, u muškaraca 67,89 godina, ali razlika u dobi nije statistički značajna, p <0,05. Ukupna srednja vrijednost vidne oštrine prije terapije bila je 0,27 ± 0,313, a nakon terapije 0,29 ± 0,313. Pacijenata s okluzijom središnje mrežnične vene bilo je 25 (53,08 %), s okluzijom gornjeg ogranka 18 (37,5 %), a s okluzijom donjeg ogranka 5 (10,42 %), pa je prosječni godišnji broj okluzije središnje mrežnične vene 5, okluzije gornjeg ogranka 3,6 i donjeg ogranka 1. Od hipertenzije je bolovalo 34 (72,34 %), a od dijabetesa samo 8 (17,02 %). Zaključak: Incidencija okluzije središnje mrežnične vene u ovom istraživanju je 4,07 novooboljelih godišnje, ogranka gornjeg i donjeg 3,74 novooboljelih u Dubrovačko-neretvanskoj županiji, a ukupna incidencija je 7,8 na 100 000 stanovnika.
Cilj: Djelotvorna i zadovoljavajuća komunikacija bolesnika i zdravstvenih djelatnika moguća je samo ako su poruke razumljive bolesniku i ako su strukturirane tako da ih bolesnici mogu lako zapamtiti. ...U istraživanju smo utvrdili razlike u razumljivosti govora u odnosu na nezavisne varijable: dobna skupina, duljina
radnoga staža, grad u kojem studenti studiraju te bračno stanje.
Metode: Istraživanjem je obuhvaćen namjerni uzorak od 68 studentica sestrinstva u Dubrovniku (24) i Zagrebu (44). Koristili smo se upitnikom Koliko sam razumljiv u govoru, s osam tvrdnji. Razlike su analizirane na razini pojedinačnih tvrdnja i ukupnog rezultata.
Rezultati: Utvrdili smo da postoji statistički bitna razlika vezana uz razumljivost govora s obzirom na dob, u smjeru boljih prosječnih rezultata za starije osobe te dvije statistički znatne razlike s obzirom na staž, u smjeru boljih prosječnih rezultata za osobe s dugotrajnijim stažem. Nema razlika u razumljivosti u govoru kad je riječ o varijablama bračno stanje ni mjesto studija (Dubrovnik/
Zagreb). Međutim, generalno nismo našli razliku u ukupnoj razumljivosti govora ni za jednu nezavisnu varijablu. U praksi bi se moglo pokušati otkriti na koje bi se načine mogla poboljšati razumljivost govora i smanjiti zapreke u komunikaciji tijekom savjetovanja.
Cancer is a global public health problem, but its exact prevalence in people with intellectual disabilities is still uncertain. This population, with limited health skills and complex health needs, ...faces many challenges in cancer prevention, screening, timely diagnosis and treatment. Furthermore, they are often underrepresented in general cancer prevention and screening policies across Europe, leading to widened disparities in health outcomes and premature mortality. Thus, unified national and local policies are needed to reduce inequalities and promoting a pan-European inclusion of people with intellectual disabilities. Our goal is to raise public awareness of this issue, including the involvement of people with intellectual disabilities, and promote engagement from relevant stakeholders. The COST Action ‘Cancer- Understanding Prevention in Intellectual Disabilities’ (CUPID) project will address health inequalities faced by people with intellectual disabilities in relation to cancer, and support the development of policy recommendations specifically tailored to their unique cognitive and healthcare needs, having a positive long-term impact on quality of life.
Members of the Inhibitor of APoptosis (IAP) protein family suppress apoptosis within tumor cells, particularly in the context of immune cell-mediated killing by the tumor necrosis factor (TNF) ...superfamily cytokines. Most IAPs are opposed endogenously by the second mitochondrial activator of caspases (SMAC), which binds to selected baculovirus IAP repeat (BIR) domains of IAPs to displace interacting proteins. The development of SMAC mimetics as novel anticancer drugs has gained impetus, with several agents now in human clinical trials. To further understand the cellular mechanisms of SMAC mimetics, we focused on IAP family members cIAP1 and cIAP2, which are recruited to TNF receptor complexes where they support cell survival through NF-κB activation while suppressing apoptosis by preventing caspase activation. We established fluorescence polarization (FP) assays for the BIR2 and BIR3 domains of human cIAP1 and cIAP2 using fluorochrome-conjugated SMAC peptides as ligands. A library of SMAC mimetics was profiled using the FP assays to provide a unique structure activity relationship (SAR) analysis compared to previous assessments of binding to XIAP. Potent compounds displayed mean inhibitory binding constants (Ki) of 9 to 27 nM against the BIR3 domains of cIAP1 and cIAP2, respectively. Selected compounds were then characterized using cytotoxicity assays in which a cytokine-resistant human tumor cell line was sensitized to either TNF or lymphotoxin-α (LT-α). Cytotoxicity correlated closely with cIAP1 and cIAP2 BIR3 binding activity with the most potent compounds able to reduce cell viability by 50%. Further testing demonstrated that active compounds also inhibit RIP1 binding to BIR3 of cIAP1 and cIAP2 in vitro and reduce steady-state cIAP1 protein levels in cells. Altogether, these data inform the SAR for our SMAC mimetics with respect to cIAP1 and cIAP2, suggesting that these IAP family members play an important role in tumor cell resistance to cytotoxicity mediated by TNF and LT-α.
There is an urgent public health need to evaluate disease severity in adults hospitalised with Delta and Omicron SARS-CoV-2 variant infections. However, limited data exist assessing severity of ...disease in adults hospitalised with Omicron SARS-CoV-2 infections, and to what extent patient-factors, including vaccination, age, frailty and pre-existing disease, affect variant-dependent disease severity.
A prospective cohort study of adults (≥18 years of age) hospitalised with acute lower respiratory tract disease at acute care hospitals in Bristol, UK conducted over 10-months. Delta or Omicron SARS-CoV-2 infection was defined by positive SARS-CoV-2 PCR and variant identification or inferred by dominant circulating variant. We constructed adjusted regression analyses to assess disease severity using three different measures: FiO2 >28% (fraction inspired oxygen), World Health Organization (WHO) outcome score >5 (assessing need for ventilatory support), and hospital length of stay (LOS) >3 days following admission for Omicron or Delta infection.
Independent of other variables, including vaccination, Omicron variant infection in hospitalised adults was associated with lower severity than Delta. Risk reductions were 58%, 67%, and 16% for supplementary oxygen with >28% FiO2 Relative Risk (RR) = 0.42 (95%CI: 0.34–0.52), P < 0.001, WHO outcome score >5 RR = 0.33 (95%CI: 0.21–0.50), P < 0.001, and to have had a LOS > 3 days RR = 0.84 (95%CI: 0.76–0.92), P < 0.001. Younger age and vaccination with two or three doses were also independently associated with lower COVID-19 severity.
We provide reassuring evidence that Omicron infection results in less serious adverse outcomes than Delta in hospitalised patients. Despite lower severity relative to Delta, Omicron infection still resulted in substantial patient and public health burden and an increased admission rate of older patients with Omicron which counteracts some of the benefit arising from less severe disease.

Whilst other studies have reported the effectiveness of mRNA vaccination against hospitalisation, including emergency department or intensive care admission, few have assessed effectiveness against ...other more clinically robust indices of COVID-19 severity.
A prospective single-centre test-negative design case–control study of adults hospitalised with COVID-19 disease or other acute respiratory disease between 1 June 2021 and 20 July 2022. We assessed VE (vaccine effectiveness) against hospitalisation, length of stay LOS >3 days, WHO COVID Score >5 and supplementary oxygen FiO2 (fraction inspired oxygen) >28%, conducting regression analyses controlling for age, gender, index of multiple deprivation, Charlson comorbidity index, time, and community infection prevalence.
935 controls and 546 cases were hospitalised during the Delta period, with 721 controls and 372 cases hospitalised during the Omicron study period. Two-dose BNT162b2 was associated with VE 82.5% 95% confidence interval 76.2%–87.2% against hospitalisation following Delta infection, 63.3% 26.9–81.8%, 58.5% 24.8–77.3%, and 51.5% 16.7–72.1% against LOS >3 days, WHO COVID Score >5, and requirement for FiO2 >28% respectively. Three-dose BNT162b2 protection against hospitalisation with Omicron infection was 30.9% 5.9–49.3%, with sensitivity analyses ranging from 28.8–72.6%. Protection against LOS >3 days, WHO COVID Score >5 and requirement for FiO2 >28% was 56.1% 20.6–76.5%, 58.8% 31.2–75.8%, and 41.5% −0.4–66.3%, respectively. In the UK, BNT162b2 was prioritised for high-risk individuals and those aged >75 years. In the latter group we found a higher estimate of VE against hospitalisation of 47.2% 16.8–66.6%.
BNT162b2 vaccination results in risk reductions for hospitalisation and multiple patient outcomes following Delta and Omicron COVID-19 infection, particularly in older adults. BNT162b2 remains effective against severe SARS-CoV-2 disease.
