RESUMEN

PURPOSE: Skin lesions in neonatal population are an emerging problem deserving attention from health care professionals. The purpose of this study is to retrospectively assess the incidence of hospital-acquired skin lesions during a 6-year period and to describe the characteristics of infants who developed them. DESIGN AND METHODS: This was a retrospective observational study conducted in a university-tertiary care center between 2015 and 2020. A descriptive analysis of the observed skin lesions is presented according to 2 time periods: 1) the implementation phase of a quality improvement program (2015-2019) and 2) the postimplementation phase (2020). RESULTS: Our findings showed an apparent increase in the incidence of all reported skin lesions throughout the study period. Pressure injuries were the most frequently reported skin lesions showing an increasing incidence over time which, however, was paralleled by a reduction in their severity. Among pressure injuries, device-related injuries were the most commonly observed (56.6% and 62.5% in the two periods, respectively) with nasal continuous positive airway pressure-related injuries accounting for 71.7% and 56.0% of lesions, respectively, and mainly affecting the nose root. The occipital area was the most frequently involved site in cases of conventional pressure injuries. CONCLUSION: Infants admitted to Neonatal Intensive Care Units may be at high risk of developing skin lesions. The adoption of appropriate preventative as well as treatment interventions could be effective in reducing the severity of pressure injuries. PRACTICE IMPLICATIONS: The implementation of quality improvement strategies may contribute to prevent skin injuries or lead to their early detection.

RESUMEN

Venipuncture is a painful and invasive procedure for hospitalised newborns and represents a challenge for neonatal healthcare professionals. This study evaluated the most efficient cannulation method based on the proportion of success at the first attempt, standard care or near-infrared (NIR) device use, and pain assessment. An observational study with two arms was conducted in the neonatal intensive care unit (NICU) of a tertiary-care university hospital in Italy. All newborns undergoing peripheral vein cannulation and only nurses with more than 5 years of professional experience in the NICU were eligible for the first arm. Only newborns with a body weight of >2500 g at cannulation and all nurses working in the NICU were involved in the second arm. In the first arm of the study, no statistically significant differences between the NIR and control groups were found in terms of proportion of successful at the first attempt 60.6% (confidence interval [CI] 95%: 48.8; 72.4) vs. 56.1% (CI 95%: 44.1; 68.0) and the mean premature infant pain profile score 6.3 (CI 95%: 5.4-7.1) vs. 5.8 (CI 95%: 5.0-6.6). In the second arm, only among less experienced nurses (<1 year), we observed a significant increase in the proportion of success in the NIR group compared with the control group, nearly tripling the success rate (72.7% [54.1; 91.3] vs. 23.1% [0.2; 46.0]).  Conclusion: This study reported no differences between the NIR and control groups. The results also suggest that using a NIR device may be advantageous for healthcare professionals with less experience during first-time cannulation. What is Known: • Venipuncture is a painful procedure commonly used to place a peripheral venous catheter for administering nutrients or drugs. • Near-infrared light facilitates the visualisation of veins and consequently, the performance of cannulation in the paediatric population. What is New: • The near-infrared light device was not associated with fewer attempts and a lower premature infant pain profile score in placing venous access in newborns than the traditional method. • The near-infrared light device could help nurses with less professional experience place a peripheral venous catheter.

RESUMEN

BACKGROUND: After the rehabilitation program, patients with left ventricular assist device (LVAD) are discharged home, but the adaption to the daily life with the implant is challenging, both with practical and psychological consequences. Literature is lacking detailed information about the quality of life of LVAD patients and caregivers after discharge to home. OBJECTIVE: This study aimed at evaluating the post-discharge outcomes of both LVAD patients and their caregivers in terms of quality of life, affectivity, and psychological health. METHODS: In this observational follow-up study, LVAD dyads discharged home from 1 year to 6 years were re-contacted by phone and received by mail an envelope with self-report questionnaires. Responses of 39 complete dyads of patients (mean age 68.59 ± 4.31; males: 92.31%) and their caregivers (mean age 61.59 ± 11.64; males: 17.95%) were analyzed. RESULTS: Patients and caregivers reported the moderate levels of anxiety, depression, and caregiver strain, and Illness denial and conscious avoidance were associated between them. The couples often reported that the LVAD has impairments for their sleep and for their affective-sexual relationship. Caregivers often reported impairment in social life and self-care. DISCUSSIONS: Despite the satisfaction for the medical and territorial assistance, patients showed psychological difficulties such as anxious and depressive symptoms and caregivers tend to neglect themselves. Even after a long time from discharge to home, the psychological distress of LVAD patients and caregivers is still considerable. Structured and continuous psychological interventions are required to support their psychological health overtime after the discharge to home.

RESUMEN

Implantable left ventricular assist devices (LVADs) are increasingly used for patients with heart failure. Despite this evidence, the psychological processes affecting implanted patients and their caregivers are only marginally studied. While common emotional reactions, such as anxiety and depression already receive attention, very little is known about the course of caregiver strain, illness denial, and their reciprocal relation. This preliminary study aims at exploring these critical topics in a cardiac rehabilitation setting, besides offering indications for future research. A total of 44 LVAD patients and caregivers were administered specific questionnaires at admission and discharge from cardiac rehabilitation. Overall, questionnaires completed at discharge showed a positive improvement in the emotional measures used. However, they also showed a worsening in the illness denial measure. We suggest that the denial process may prepare patients and caregivers in returning home. Moreover, we conclude that studying only the common emotional reactions may limit the understanding of the psychological process adaptation to severe illness.

RESUMEN

Few studies evaluated the effect of cardiac rehabilitation programs on perceived emotional and health status of left ventricular assist device (LVAD) patients, and none explored their effect on caregivers' strain. We enrolled 119 adult LVAD patients, together with their caregivers (n = 91), in two Rehabilitation Institutes that provided inpatient multidisciplinary activities. At admittance and prior to discharge they completed questionnaires evaluating patient emotional state and subjective perception of health status, caregiver strain, and patient and caregiver perception of the VAD. Six months after discharge, patients and caregivers were contacted again and asked specific questions about their quality of life. Patients' state anxiety and depression symptoms significantly diminished at discharge (0.000), whereas their perception of general health status rose (0.000). Caregivers' perceived strain also significantly decreased (0.001) and the perceived device management skill grew both for patients and caregivers (0.000). A substantial amount (36%) of psychologically frail patients and caregivers, although improving their emotional condition, never reached that of the less frail subjects. At the 6-month follow-up, both patients and caregivers appeared stable in evaluating respectively their general health and their caregiving-related strain, compared to discharge. Our data show that a comprehensive inpatient rehabilitation program improves the emotional state of LVAD patients and of their caregivers, even in psychologically frailer subjects. Team approach makes patients and caregivers self-confident about device management, increasing their knowledge, clarifying their doubts, and encouraging them to handle the difficulties met during the rehabilitation period, suggesting strategies to cope with daily life at home.

RESUMEN

OBJECTIVES: Patients implanted with a Left Ventricular Assist Device (LVAD) constitute a new population of chronic heart failure (HF) patients requiring continuous medical support and representing heavy costs - both direct and indirect - for the healthcare system. If there is consensus about the increased survival, the psychosocial outcomes, in terms of psychological wellbeing, behavioral and social functioning of both patients and caregivers, are still unclear. Overall, it is not clear if local health and social services are equipped to support them in their needs. We conducted an observational study on the psychosocial characteristics and needs of LVAD patients. METHODS: Twenty-seven patients admitted for rehabilitation after implantation, and their caregivers were recruited. On admission, patients and caregivers were administered questionnaires assessing anxiety, depression, quality of life, level of social complexity and were interviewed about their social resources. At discharge, patients were re-assessed by questionnaires and patients/caregivers received a follow-up phone-interview after 8-12 months. RESULTS: LVAD patients' emotional well-being and subjective quality of life improved during the rehabilitation stay and they confirmed their satisfaction with LVAD at follow-up. Problems emerged concerning the inadequate health and social assistance that LVAD patients receive once home. More than 50% of patients showed substantial social complexity, the burden of which fell on the caregivers, whose strain hardly declined over time, remaining at a level requiring psychological attention. CONCLUSIONS: Technological advances that improve LVAD patients' survival should be rapidly followed by adequate interventions by policy makers to improve also the local health/social assistance provided and to address patients and caregivers psychosocial needs over time.

RESUMEN

Left ventricular assist devices (LVADs) have progressively evolved, particularly in the last 10 years, to serve patients affected by severe heart failure as a bridge to transplant or destination therapy. The survival rate and quality of life of pre- and postimplant patients, as well as caregivers' perceptions and distress, are under investigation by the scientific community. But what caregivers think and feel after the loss of their loved one has not so far been examined. We contacted 16 principal caregivers of deceased LVAD patients by telephone. They were asked to evaluate their experience with LVADs and were administered a specific questionnaire about their mourning, the Caregiver Mourning Questionnaire (CMQ), to evaluate their perceptions of the physical, emotional, and social support-related problems that they had experienced during the previous 3 months. Positive aspects reported by the caregivers were the patient's overall subjective well-being and increased survival. Negative aspects were the difficulty to manage infections and the driveline, and the incomplete autonomy of the patient. Half of the caregivers reported not being preadvised about many of the problems they would face. The CMQ revealed that numerous caregivers had health problems, difficulty in sleeping, eating disorders, lack of energy, and loneliness. Use of psychotropic drugs and regrets about how they assisted their loved one also emerged. In conclusion, caregivers of LVAD patients may experience complicated mourning. Our data support in particular the need for an early intervention of palliative care which could prevent or reduce complicated mourning.

RESUMEN

The approach to patients affected by motor neuron disease (MND) and their caregivers requires specific training for the care-team. In fact, the progression of the disease, with the decline of physical--and sometimes cognitive--function, the increasing difficulties in speaking, breathing, and swallowing and the need of invasive choices, as the artificial nutrition and tracheostomy, constitute a challenge for the health professionals, often generating distress. For this reason, their cohesion and sharing abilities are fundamental. Psychologist assumes a strategic role in supporting and facilitating the analysis of clinical cases and of the team's intra/interpersonal dynamics. For this aim, he/she needs specific training and instruments. We here present a semi-structured interview--the Motor Neuron Disease-Psychological Interview (MoNeDi-PI)--which may guide in the psychological assessment of patients affected by MNDs and their caregivers. It can also be a handy reference tool for other members of the healthcare team providing necessary information about the patient and caregiver in order to optimize clinical decision making about which health interventions to apply.

RESUMEN

Systemic inflammation is known to target tubular epithelial cells (TECs), leading to acute kidney injury. Tubular cells have been implicated in the response to inflammatory mediators in ischaemic and septic renal damage. Moreover, loss of tubular cells by apoptosis or epithelial-to-mesenchymal transition may ingenerate conditions that lead to progression towards chronic kidney disease. On the other hand, TECs may actively contribute to the production of inflammatory mediators that may propagate the injury locally or in distant organs. In the present review, we discuss the tubular cell response and its contribution to systemic inflammation.

RESUMEN

In critically ill patients, any acute organ injury is associated with a sudden change of circulating factors that may play a role in distant organ dysfunction through a complex cross-talk. In this issue, Virzì and colleagues discuss the relevance of humoral signalling between heart and kidney, focusing on type 1 and type 3 cardio-renal syndrome. We herein review the mechanisms of heart-kidney cross-talk, discussing the role of circulating detrimental mediators in the pathogenetic mechanisms of cardio-renal syndrome.

RESUMEN

Purpose: Aim of the present study is to characterize a deep learning-based auto-segmentation software (DL) for prostate cone beam computed tomography (CBCT) images and to evaluate its applicability in clinical adaptive radiation therapy routine. Materials and methods: Ten patients, who received exclusive radiation therapy with definitive intent on the prostate gland and seminal vesicles, were selected. Femoral heads, bladder, rectum, prostate, and seminal vesicles were retrospectively contoured by four different expert radiation oncologists on patients CBCT, acquired during treatment. Consensus contours (CC) were generated starting from these data and compared with those created by DL with different algorithms, trained on CBCT (DL-CBCT) or computed tomography (DL-CT). Dice similarity coefficient (DSC), centre of mass (COM) shift and volume relative variation (VRV) were chosen as comparison metrics. Since no tolerance limit can be defined, results were also compared with the inter-operator variability (IOV), using the same metrics. Results: The best agreement between DL and CC was observed for femoral heads (DSC of 0.96 for both DL-CBCT and DL-CT). Performance worsened for low-contrast soft tissue organs: the worst results were found for seminal vesicles (DSC of 0.70 and 0.59 for DL-CBCT and DL-CT, respectively). The analysis shows that it is appropriate to use algorithms trained on the specific imaging modality. Furthermore, the statistical analysis showed that, for almost all considered structures, there is no significant difference between DL-CBCT and human operator in terms of IOV. Conclusions: The accuracy of DL-CBCT is in accordance with CC; its use in clinical practice is justified by the comparison with the inter-operator variability.

RESUMEN

The transition from vegetative to reproductive development is one of the most important phase changes in the plant life cycle. This step is controlled by various environmental signals that are integrated at the molecular level by so-called floral integrators. One such floral integrator in Arabidopsis (Arabidopsis thaliana) is the MADS domain transcription factor SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1). Despite extensive genetic studies, little is known about the transcriptional control of SOC1, and we are just starting to explore the network of genes under the direct control of SOC1 transcription factor complexes. Here, we show that several MADS domain proteins, including SOC1 heterodimers, are able to bind SOC1 regulatory sequences. Genome-wide target gene analysis by ChIP-seq confirmed the binding of SOC1 to its own locus and shows that it also binds to a plethora of flowering-time regulatory and floral homeotic genes. In turn, the encoded floral homeotic MADS domain proteins appear to bind SOC1 regulatory sequences. Subsequent in planta analyses revealed SOC1 repression by several floral homeotic MADS domain proteins, and we show that, mechanistically, this depends on the presence of the SOC1 protein. Together, our data show that SOC1 constitutes a major hub in the regulatory networks underlying floral timing and flower development and that these networks are composed of many positive and negative autoregulatory and feedback loops. The latter seems to be crucial for the generation of a robust flower-inducing signal, followed shortly after by repression of the SOC1 floral integrator.

RESUMEN

Cement asbestos slates, commonly known as Eternit® and still abundant in private and public buildings, were deactivated through a thermal process. The resulting deactivated cement asbestos powder (DCAP), a mixture of Ca-Mg-Al silicates and glass, was compounded with Pavatekno Gold 200 (PT) and Pavafloor H200/E (PF), two different epoxy resins (bisphenol A epichlorohydrin) for flooring applications. The addition of the DCAP filler to the PF samples causes a slight but acceptable decrease in the relevant mechanical properties (compressive, tensile, and flexural strengths) upon increasing DCAP content. The addition of the DCAP filler to pure epoxy (PT resin) causes a slight decrease in the tensile and flexural strengths with increasing DCAP content, while the compressive strength is almost unaffected, and the Shore hardness increases. The main mechanical properties of the PT samples are significantly better than those of the filler-bearing sample of normal production. Overall, these results suggest that DCAP can be advantageously used as filler in addition to, or in substitution for, commercial barite. In particular, the sample with 20 wt% of DCAP is the best performing in terms of compressive, tensile, and flexural strengths, whereas the sample with 30 wt% of DCAP shows the highest Shore hardness, which is an important property to be considered in flooring applications.

RESUMEN

The synthesis of hydrogels that are based on poly-hydroxyethyl methacrylate, p(HEMA), network semi-interpenetrated with linear polyvinylpyrrolidone (PVP) was optimized in order to allow both a fast preparation and a high cleaning effectiveness of artistic surfaces. For this purpose, the synthesis parameters of the gel with PVP having a high molecular weight (1300 kDa) that were reported in the literature, were modified in terms of temperature, time, and crosslinker amount. In addition, the gel composition was modified by using PVP with different molecular weights, by changing the initiator and by adding maleic anhydride. The modified gels were characterized in terms of equilibrium water content (EWC), water uptake, conversion grade, and thermal properties by differential scanning calorimetry (DSC). The cleaning effectiveness of the gels was studied through the removal of copper salts from laboratory-stained specimens. Cleaning materials were characterized by electron paramagnetic resonance (EPR) spectroscopy, ultraviolet-visible (UV-Vis) spectroscopy, and inductively-coupled plasma-mass spectrometry (ICP-MS). Cleaning was assessed on marble specimens by color variation measurements. The gel synthesis is accelerated by using PVP 360 kDa. The addition of maleic anhydride in the p(HEMA)/PVP network allows the most effective removal of copper salt deposits from marble since it acts as a chelator towards copper ions.

RESUMEN

We previously reported on a cohort of breast cancer patients affected with ductal carcinoma in situ (DCIS) that were treated with breast conservative surgery and hypofractionated whole-breast radiotherapy with a concomitant boost to the lumpectomy cavity. We now report on the long-term results of the oncological and toxicity outcomes, at a median follow-up of 11.2 years. We also include an analysis of the predictive factors for local recurrence (LR). Eighty-two patients with long-term observation were considered for this report. All received hypofractionated post-operative radiotherapy with a concomitant boost (45 Gy/20 fractions to the whole breast and 50 Gy/20 fractions to the lumpectomy cavity). We report on LC rates at 5 and 10 years, overall survival (OS), and breast-cancer-specific survival (BCSS), employing the Kaplan-Meier method. Cox proportional regression analysis was used to determine the role of selected clinical parameters on the risk of local recurrence, by the univariate and multivariate models. After a median follow-up of 11.2 years (range 5-15 years), 9 pts (11%) developed LR. The LR rates at 5 years and 10 years were 2.4% and 8.2%, respectively. The 5- and 10-year overall survival rates were 98.8% and 91.6%, respectively. The 5- and 10-year breast-cancer-specific survival rates were 100.0% and 99.0%. Late skin and subcutaneous toxicities were generally mild, and cosmetic results were good-excellent for most patients. For the univariate regression analysis, ER positive status (HR; 95% CI, p = 0.021), PgR positive status (HR; 95% CI, p = 0.012), and the aggregate data of positive hormonal status (HR; 95% CI, p = 0.021) were inversely correlated to LR risk. Conversely, a high tumor grade (G3) was directly correlated with the risk of LR (HR; 95% CI, p = 0.048). For the multivariate regression analysis, a high tumor grade (G3) confirmed its negative impact on LR (HR 0.40; 95% CI 0.19-0.75, p = 0.047). Our long-term data demonstrate hypofractionated whole-breast radiotherapy with a concomitant boost to be feasable, effective, and tolerable. Our experience suggests positive hormonal status to be protective with respect to LR risk. A high tumor grade is a risk factor for LR.

RESUMEN

Proper delineation of both target volumes and organs at risk is a crucial step in the radiation therapy workflow. This process is normally carried out manually by medical doctors, hence demanding timewise. To improve efficiency, auto-contouring methods have been proposed. We assessed a specific commercial software to investigate its impact on the radiotherapy workflow on four specific disease sites: head and neck, prostate, breast, and rectum. For the present study, we used a commercial deep learning-based auto-segmentation software, namely Limbus Contour (LC), Version 1.5.0 (Limbus AI Inc., Regina, SK, Canada). The software uses deep convolutional neural network models based on a U-net architecture, specific for each structure. Manual and automatic segmentation were compared on disease-specific organs at risk. Contouring time, geometrical performance (volume variation, Dice Similarity Coefficient-DSC, and center of mass shift), and dosimetric impact (DVH differences) were evaluated. With respect to time savings, the maximum advantage was seen in the setting of head and neck cancer with a 65%-time reduction. The average DSC was 0.72. The best agreement was found for lungs. Good results were highlighted for bladder, heart, and femoral heads. The most relevant dosimetric difference was in the rectal cancer case, where the mean volume covered by the 45 Gy isodose was 10.4 cm3 for manual contouring and 289.4 cm3 for automatic segmentation. Automatic contouring was able to significantly reduce the time required in the procedure, simplifying the workflow, and reducing interobserver variability. Its implementation was able to improve the radiation therapy workflow in our department.

RESUMEN

The optimal timing of surgery after neoadjuvant chemoradiotherapy (CRT) in locally advanced rectal cancer is still controversial. Aim of this study was to evaluate the effect of increasing time interval between the end of CRT and surgery on pathological outcomes. This is a retrospective analysis on 114 patients treated with long-course neoadjuvant RT with or without chemotherapy between January 2005 and September 2020. 43 patients underwent surgery within 10 weeks from the end of CRT (1st group), whereas 71 patients underwent total mesorectal excision with a time interval equal or greater than 10 weeks (2nd group). Primary endpoint was pCR (pathological complete response). Secondary endpoints were near pCR (ypT0-1 N0), tumor downstaging (ypT less than cT), nodal downstaging (ypN less than cN), and overall response comparing clinical with pathological TN stage. Overall, the pCR rate was 8.8%, whereas we observed no significantly difference in primary endpoint between the two groups. Considering near pCR, a trend toward significant difference in favor of 2nd group was seen (p = 0.072). Tumor and nodal downstaging rates were 39.5%, 41.9%, 59.2%, and 56.3% in the 1st and 2nd group, respectively, with a statistically significant difference for T category (p = 0.042). Overall response rates (TN stage) showed a trend toward significant difference in favor of patients of the ≥ 10 week group (p = 0.059). Our study suggests that a prolonged time interval between the end of CRT and surgery (≥ 10 weeks) increases pathological response rates.

RESUMEN

The P2Y-like receptor GPR17 is expressed by adult neural progenitor cells, suggesting a role in lineage determination. Here, we characterized GPR17 expression and function in mouse cortical primary astrocytes/precursor cell cultures. GPR17 is expressed by a subpopulation of oligodendrocyte precursor cells (OPCs), but not by astrocytes. This expression pattern was also confirmed in vivo. In vitro, GPR17 expression was markedly influenced by culturing conditions. In the presence of growth factors (GFs), no significant GPR17 expression was found. When cultures were shifted to a differentiating medium, a dramatic, time-dependent increase in the number of highly branched GPR17-positive cells was observed. Under these conditions, GPR17 was induced in the totality of O4-positive immature oligodendrocytes. Instead, in cultures originally grown in the absence of GFs, GPR17 was already expressed in morphologically more mature OPCs. Shifting of these cultures to differentiating conditions induced GPR17 only in a subpopulation of O4-positive cells. Under both culture protocols, appearance of more mature CNPase- and MBP-positive cells was associated to a progressive loss of GPR17. GPR17 expression also sensitized cells to adenine nucleotide-induced cytotoxicity, whereas activation with uracil nucleotides promoted differentiation towards a more mature phenotype. We suggest that GFs may keep OPCs in a less differentiated stage by restraining GPR17 expression, and that, under permissive conditions, GPR17 contributes to OPCs differentiation. However, upon high extracellular adenine nucleotide concentrations, as during trauma and ischemia, GPR17 sensitizes cells to cytotoxicity. This double-edged sword role may be exploited to unveil new therapeutic approaches to acute and chronic brain disorders.

RESUMEN

Introduction: Healthcare workers facing the threatening COVID-19 can experience severe difficulties. Despite the need to evaluate both the psychological distress and positive protective resources, brief and reliable assessment tools are lacking. Aim: Study 1 aimed at developing a new assessment tool to measure psychological distress and esteem in healthcare workers during the COVID-19 pandemic. Study 2 aimed to explore and compare the psychological reactions of healthcare workers of the COVID-19 and the non-COVID-19 wards. Methods: In Study 1, psychologists created 25 items based on their clinical experience. A preliminary qualitative evaluation selected the best 15 items for the new tool (CPI-HP) assessing the COVID-19 psychological impact with 2 scales: psychological distress and esteem. The CPI-HP was administered to 110 healthcare professionals to study its psychometric properties and the internal structure with exploratory graph analysis and confirmatory factor analysis. Study 2 compared two groups of healthcare professionals of the COVID-19 and non-COVID-19 departments. Results: In Study 1, the CPI-HP showed satisfying psychometric properties, and the two-factor structure was confirmed with good fit indices. In Study 2, the two groups of healthcare workers showed comparable levels of psychological distress and resilient coping, but the COVID-19 group displayed significantly higher esteem and appreciation of the experience. Discussion: All operators showed high psychological distress during the emergency, but the COVID-19 group reported higher resources, probably due to stronger group cohesion and greater esteem, perceived meaning, and own work value. Conclusion: Assessing the psychological distress and resources of healthcare professionals with specific tools is important. Psychological interventions should promote their psychological health.

RESUMEN

PURPOSE: COVID-19 patients faced first-hand the life-threatening consequences of the disease, oftentimes involving prolonged hospitalization in isolation from family and friends. This study aimed at describing the psychological intervention to address the psychological difficulties and issues encountered by the hospitalized post-acute COVID-19 patients in a rehabilitation setting. PATIENTS AND METHODS: Patients' demographics, medical diagnosis, and neuro-psychological information were collected from March 2nd to May 12th, 2020. The main psychological issues and intervention strategies were collected. RESULTS: A total of 181 patients were hospitalized during this period. Among them, the 47.5% underwent psychological assessment (N=86; age: 74.58±13.39; 54.7% females). The most common psychological issues were acute stress disorders (18.6%), anxious and demoralization symptoms (26.7%), depression (10.5%%), and troublesome grief (8.1%). Once recovered from COVID-19, many patients were discharged home (38.4%), some received further rehabilitation in non-COVID-19 wards (41.9%), mostly due to pre-existent diseases (72.2%) rather than to COVID-19 complications (27.8%). CONCLUSION: A great number of the hospitalized post-acute COVID-19 patients showed psychological issues requiring psychological intervention, the most common were anxiety, demoralization, acute stress, depression, and grief. The proposed psychological treatment for hospitalized COVID-19 patients was conducted in a Cognitive Behavioral framework. In particular, during the COVID-19 pandemic, psychological intervention is an important part of rehabilitation in the post-acute phase of the illness to reduce distress symptoms and improve psychological health.
