[Unfinished Nursing Care and their consequences as perceived by nurses: a descriptive qualitative study]. / Unfinished Nursing Care e le conseguenze percepite dagli infermieri: uno studio qualitativo descrittivo.

Unfinished Nursing Care, which expresses the nursing care planned but not delivered or delivered late, is a phenomenon of growing interest in recent years resulting in several conceptual frameworks, each of which has defined what are the consequences of the phenomenon. However, outcomes established to date have not been re-assessed over time and from different perspectives, including also the nurse managers and directors. The aim of the study was to describe the consequences of Unfinished Nursing Care in daily practice as perceived by clinical nurses, nurse managers and directors. A descriptive qualitative study based on interviews was conducted in 2021; data has been analyzed through content analysis, and reported here in accordance with the Consolidated criteria for reporting qualitative research (COREQ) guidelines. The consequences of Unfinished Nursing Care have been set at three levels: outcomes for the nurse (increased frustration, anxiety, helplessness, work overtime), outcomes for the patient (increased risk of infections related to care practices, bed rest syndrome; loss of independence and quality of life, disorientation; increase episodes of in undefined care pathways, aggression towards staff, decrease in compliance and increased the length of in-hospital stay) and outcomes affecting the relationship with family caregivers (difficulties in the relationship, disappointment, increased risk of complaints).

Rare Risk Variants Identification by Identity-by-Descent Mapping and Whole-Exome Sequencing Implicates Neuronal Development Pathways in Schizophrenia and Bipolar Disorder.

Schizophrenia (SCZ) and bipolar disorder (BPD) are highly heritable disorders with an estimated co-heritability of 68%. Hundreds of common alleles have been implicated, but recently a role for rare, high-penetrant variants has been also suggested in both disorders. This study investigated a familial cohort of SCZ and BPD patients from a closed population sample, where the high recurrence of the disorders and the homogenous genetic background indicate a possible enrichment in rare risk alleles. A total of 230 subjects (161 cases, 22 unaffected relatives, and 47 controls) were genetically investigated through an innovative strategy that integrates identity-by-descent (IBD) mapping and whole-exome sequencing (WES). IBD analysis allowed to track high-risk haplotypes (IBDrisk) shared exclusively by multiple patients from different families and possibly carrying the most penetrant alleles. A total of 444 non-synonymous sequence variants, of which 137 disruptive, were identified in IBDrisk haplotypes by WES. Interestingly, gene sets previously implicated in SCZ (i.e., post-synaptic density (PSD) proteins, voltage-gated calcium channels (VGCCs), and fragile X mental retardation protein (FMRP) targets) were found significantly enriched in genes carrying IBDrisk variants. Further, IBDrisk variants were preferentially affecting genes involved in the extracellular matrix (ECM) biology and axon guidance processes which appeared to be functionally connected in the pathway-derived meta-network analysis. Results thus confirm rare risk variants as key factors in SCZ and BPD pathogenesis and highlight a role for the development of neuronal connectivity in the etiology of both disorders.

A data-driven network model of primary myelofibrosis: transcriptional and post-transcriptional alterations in CD34+ cells.

microRNAs (miRNAs) are relevant in the pathogenesis of primary myelofibrosis (PMF) but our understanding is limited to specific target genes and the overall systemic scenario islacking. By both knowledge-based and ab initio approaches for comparative analysis of CD34+ cells of PMF patients and healthy controls, we identified the deregulated pathways involving miRNAs and genes and new transcriptional and post-transcriptional regulatory circuits in PMF cells. These converge in a unique and integrated cellular process, in which the role of specific miRNAs is to wire, co-regulate and allow a fine crosstalk between the involved processes. The PMF pathway includes Akt signaling, linked to Rho GTPases, CDC42, PLD2, PTEN crosstalk with the hypoxia response and Calcium-linked cellular processes connected to cyclic AMP signaling. Nested on the depicted transcriptional scenario, predicted circuits are reported, opening new hypotheses. Links between miRNAs (miR-106a-5p, miR-20b-5p, miR-20a-5p, miR-17-5p, miR-19b-3p and let-7d-5p) and key transcription factors (MYCN, ATF, CEBPA, REL, IRF and FOXJ2) and their common target genes tantalizingly suggest new path to approach the disease. The study provides a global overview of transcriptional and post-transcriptional deregulations in PMF, and, unifying consolidated and predicted data, could be helpful to identify new combinatorial therapeutic strategy.

A new mathematical model based on clinical and laboratory variables for the diagnosis of Sjögren's syndrome.

Sjögren's syndrome (SS) is a systemic autoimmune disease that mainly affects exocrine glands. A diagnosis of SS in its early stages has a potential clinical relevance, but it is difficult and cannot be made solely on clinical grounds. Several sets of diagnostic criteria have been proposed, but none has met with a general consensus. Minor salivary gland has been judged to be the "gold standard" for the diagnosis of SS. However, it is a painful procedure and has a small but significant proportion of both false positive and false negative results. The aim of our study was to develop a simple mathematical score that uses clinical and laboratory variables for diagnosing SS, thereby reducing the need of minor salivary gland. The following variables were included in the model: ANA, SS-A/SS-B, Schirmer's Test/BUT, C3/C4, serum gammaglobulin levels. One hundred consecutive individuals reporting clinical syndromes consistent with a sicca syndrome were included in the study. The application of our multifactorial mathematical model has shown a high predictive value for SS vs controls or vs patients with other autoimmune disorders (Sensitivity 93%, Specificity 100%), with an estimated minor salivary gland reduction of 77%. We conclude that our mathematical model can be considered a useful non-invasive approach for diagnosing Sjogren's Syndrome and recommend its validation on a larger scale.

Evaluation of primary surgical procedures for retinal detachment with macular hole in highly myopic eyes: a comparison [corrected] of vitrectomy versus posterior episcleral buckling surgery.

PURPOSE: To evaluate postoperative outcomes between pars plana vitrectomy (PPV) and posterior episcleral buckle procedure (PEBP) in myopic eyes with retinal detachment (RD) and macular hole (MH). DESIGN: Retrospective nonrandomized comparative interventional trial. PARTICIPANTS AND INTERVENTION: The study included 30 phakic, highly myopic eyes (from 19-30 negative diopters) of 30 patients with an RD and MH. The patients were divided into two groups: They were assigned to PPV (15 eyes, group A) or to PEBP (15 eyes, group B). No significant (P > 0.01) differences in preoperative visual acuity (VA) between group A and group B eyes were found. Follow-up was 12 months. MAIN OUTCOME MEASURES: Anatomic attachment of the retina was determined, and VA was measured. RESULTS: Retinal reattachment was obtained on 11 of 15 (73.3%) eyes of group A and on 14 of 15 (93.3%) eyes of group B. In group A eyes the VA was substantially unmodified after surgical treatment, whereas in group B eyes the VA observed after surgical treatment increased significantly (P < 0.001) with respect to the preoperative values. CONCLUSIONS: PEBP resulted in better postoperative anatomic and functional results compared with PPV in eyes with extreme degrees of myopia, pronounced posterior staphyloma, and posterior vitreous schisis affected with RD caused by MH.

Morphological evaluation of full-thickness idiopathic macular holes by optical coherence tomography.

PURPOSE: To assess the efficacy of optical coherence tomography (OCT) for the morphological evaluation of idiopathic full-thickness macular holes and for detecting any morphological changes with time. METHODS: Serial sagittal tomographs through the macula were taken by OCT in a consecutive series of 34 eyes of 34 patients with diagnosis of idiopathic full-thickness macular hole. The patients were divided into two groups on the basis of "recent" (group 1, 25 patients) or "not-recent" (group 2, 9 patients) onset of symptoms related to the macular hole. Fourteen of the 25 patients in group 1 and all nine in group 2 underwent vitrectomy. The 11 in group 1 who refused surgery were observed by OCT examination with follow-up from 6 to 13 months. RESULTS: In most eyes OCT scans revealed two different anatomical features of macular holes depending on the time of onset of symptoms. Eleven of the 14 "recent-onset" holes that underwent surgery showed "sharp", undermining edges at preoperative OCT; the other three had "rounded" edges. Seven of the nine eyes operated for long-standing full-thickness macular holes had preoperative "rounded" edges, while the edges in the remaining two eyes were "sharp". OCT of eight of the 11 non-operated eyes in group 1 showed a morphological evolution of the macular hole edges from a "sharp" to a "rounded" contour and an increase in the diameter of the hole. CONCLUSIONS: OCT can help in the morphological evaluation of idiopathic full-thickness macular holes and in the detection of morphological changes with time.

Optical coherence tomography.

The optical coherence tomograph is a new, noninvasive technical device that can obtain cross-sectional, high-resolution images-optical coherence tomographs (OCT)-of the retina. This instrument permits an accurate evaluation of various macular and chorioretinal pathologies and the early detection of glaucomatous damage. Images of the retina are obtained similar to ultrasound B-scan, with 10-microm longitudinal resolution. Because the OCT operates with a near-infrared wavelength (about 840 nm), the examination is of minimal discomfort for the patient. OCT examination is indicated in cases of macular pathologies such as vitreoretinal interface syndrome, in the early detection and quantitative assessment of macular edema, and in the evaluation of a glaucomatous damage by measuring the retinal nerve fiber layer thickness. The future role of this instrument and its applications for clinical diagnosis depend on the future improvement and updating of the software.

Copper intraocular foreign body: diagnosis and treatment.

Copper intraocular foreign bodies (IOFB) are relatively common after penetrating eye injuries. Ocular signs and symptoms vary greatly in relation to the copper content, ranging from chronic uveitis and severe visual loss for IOFB containing more than 85% copper, to local copper deposits with no severe ocular damage for less toxic alloys. Reported here is the case of a ten-year-old boy who suffered from recurrent chronic uveitis five months after a perforating eye injury due to copper wire. Diagnostic ultrasound and computerized tomography revealed an IOFB within the lens and X-ray spectrometry (DXS) indicated the nature of the IOFB as copper, and accurately measured the dissolution of the metal. The patient underwent cataract extraction and standard three-port pars plana vitrectomy with gas-fluid exchange. Twelve months after surgery the retina was flat and visual acuity had risen to 20/60. Undiluted vitreous samples obtained in the course of the intervention, studied by immunohistochemical techniques, showed an inflammatory reaction with a prevalence of PMN-N and CD3 T-lymphocytes. DXS thus appears to be a new and reliable diagnostic tool for the early detection and management of copper and other toxic metal IOFB.

Pattern electroretinogram in treated ocular hypertension: a cross-sectional study after timolol maleate therapy.

To investigate pattern electroretinogram changes in treated ocular hypertension, we evaluated pattern electroretinogram recordings of 48 hypertensive eyes following an 8-month timolol maleate therapy. During treatment, 27 of 48 eyes had normalized intraocular pressures (15-18 mm Hg), while 21 retained elevated values (21-25 mm Hg). Twenty-eight eyes with untreated hypertension (22-25 mm Hg) lasting at least 8 months, as well as 32 untreated, normotensive eyes served as controls. When compared to untreated normotensive controls, timolol-treated eyes with either elevated or normalized intraocular pressures showed reductions in the mean electroretinographic amplitudes. However, these amplitude reductions were substantially greater in treated eyes with elevated pressures as compared to those with normalized ones. Untreated hypertensive controls showed pattern electroretinogram reductions, with respect to normal values, that were comparable to those of treated hypertensive eyes, but larger than those of treated normotensive ones. These results indicate that, in treated ocular hypertension, pattern electroretinogram losses tend to be associated with moderately increased intraocular pressures in the range of 21-25 mm Hg. Electroretinographic abnormalities may be, at least in part, prevented only by lowering intraocular pressure into a normal range.

Analgesic effect of topical diclofenac versus betamethasone after posterior segment surgery.

BACKGROUND: In clinical use, topical diclofenac, a nonsteroidal antiinflammatory, was found to be remarkably effective as an analgesic. A trial was therefore conducted to quantify and compare this effect with that of other drugs commonly used after posterior segment surgery. METHODS: A single-blind, randomized study of 37 patients undergoing posterior segment surgery was conducted. On the day of surgery and for 30 days thereafter, one group received topical diclofenac 0.1% and one group received topical betamethasone 0.1%. Pain intensity was assessed by two standard psychologic tests, the McGill Pain Questionnaire (MPQ) and Scott's Visual Analogic Scale (VAS). RESULTS: The group receiving diclofenac had significantly lower pain scores on the MPQ at days 1 and 15 (P < 0.05 and P < 0.03, respectively). The VAS scores were also statistically lower for this group on day 15 (P < 0.03). CONCLUSION: Topical diclofenac 0.1% has greater analgesic action than topical betamethasone 0.1% without the side effects of steroids, and may be useful after posterior segment surgery.
