RESUMO

BACKGROUND AND OBJECTIVE: Polypharmacy is common in older adults, particularly among those living in long-term care facilities. This condition represents a marker of clinical complexity and might directly affect the immunological response. However, there are limited data on the association of polypharmacy with vaccine immunogenicity. This study evaluated the immune response to anti-SARS-CoV-2 vaccines in older residents of long-term care facilities as a function of the number of medications used. METHODS: In 478 long-term care facility residents participating in the GeroCovid Vax study, we assessed SARS-CoV-2 trimeric S IgG levels through chemiluminescent assays before the vaccination and after 2, 6, and 12 months. A booster dose was administered between 6- and 12-month assessments. Sociodemographic information and data on chronic diseases and medications were derived from medical records. Based on the number of daily medications, residents were classified into the no polypharmacy (zero to four medications), polypharmacy (five to nine medications), and hyperpolypharmacy (ten or more medications) groups. RESULTS: In the sample (mean age 82.1 years, 69.2% female), 200 (41.8%) residents were taking five or fewer medications/day (no polypharmacy), 229 (47.9%) had polypharmacy, and 49 (10.3%) had hyperpolypharmacy. Using linear mixed models adjusted for potential confounders, we found that hyperpolypharmacy was associated with a steeper antibody decline after 6 months from the first vaccine dose administration (ß = - 0.29, 95% confidence interval - 0.54, - 0.03, p = 0.03) than no polypharmacy, while no significant differences were observed at 12 months. CONCLUSIONS: The humoral immune response to SARS-CoV-2 vaccination of older residents showed only slight changes as a function of the number of medications taken. Although it seemed less durable among older residents with hyperpolypharmacy, the booster dose administration equalized such a difference.

RESUMO

OBJECTIVES: Nursing home (NH) residents have been significantly affected by the coronavirus disease 2019 (COVID-19) pandemic. Studies addressing the immune responses induced by COVID-19 vaccines in NH residents have documented a good postvaccination antibody response and the beneficial effect of a third booster vaccine dose. Less is known about vaccine-induced activation of cell-mediated immune response in frail older individuals in the long term. The aim of the present study is to monitor messenger RNA SARS-CoV-2 vaccine-induced T-cell responses in a sample of Italian NH residents who received primary vaccine series and a third booster dose and to assess the interaction between T-cell responses and humoral immunity. DESIGN: Longitudinal cohort study. SETTING AND PARTICIPANTS: Thirty-four residents vaccinated with BNT162b2 messenger RNA SARS-CoV-2 vaccine between February and April 2021 and who received a third BNT162b2 booster dose between October and November 2021 were assessed for vaccine-induced immunity 6 (prebooster) and 12 (postbooster) months after the first BNT162b2 vaccine dose. METHODS: Pre- and postbooster cell-mediated immunity was assessed by intracellular cytokine staining of peripheral blood mononuclear cells stimulated in vitro with peptides covering the immunodominant sequence of SARS-CoV-2 spike protein. The simultaneous production of interferon-γ, tumor necrosis factor-α, and interleukin-2 was measured. Humoral immunity was assessed in parallel by measuring serum concentration of antitrimeric spike IgG antibodies. RESULTS: Before the booster vaccination, 31 out of 34 NH residents had a positive cell-mediated immunity response to spike. Postbooster, 28 out of 34 had a positive response. Residents without a previous history of SARS-CoV-2 infection, who had a lower response prior the booster administration, showed a greater increase of T-cell responses after the vaccine booster dose. Humoral and cell-mediated immunity were, in part, correlated but only before booster vaccine administration. CONCLUSIONS AND IMPLICATIONS: The administration of the booster vaccine dose restored spike-specific T-cell responses in SARS-CoV-2 naïve residents who responded poorly to the first immunization, while a previous SARS-CoV-2 infection had an impact on the magnitude of vaccine-induced cell-mediated immunity at earlier time points. Our findings imply the need for a continuous monitoring of the immune status of frail NH residents to adapt future SARS-CoV-2 vaccination strategies.

RESUMO

OBJECTIVE: This study evaluates long-term outcomes in adults with Unilateral and Bilateral Cleft Lip and Palate (UCLP/BCLP) treated during the period 1992 to 1995 with tibial periosteal graft in primary repair. DESIGN: Retrospective study. SETTING: Department of Plastic and Maxillofacial Surgery, Children's Hospital Bambino Gesù (Italy). PATIENTS: The study included 52 patients with non-syndromic BCLP/UCLP who met the inclusion criteria. INTERVENTIONS: All patients underwent a standardized surgical protocol using a tibial periosteal graft as primary repair of the hard palate. MAIN OUTCOME MEASURE(S): Long-term outcomes on maxillary growth, residual oronasal fistula, and leg length discrepancy. RESULTS: About <2% of patients showed oral-nasal communication. Mean value of maxillary depth was 86° ± 4.5°. The lower value for maxillary retrusion was 76.8° in relation to the Frankfurt plane. At the x-ray control, 12.2% of patients showed leg discrepancy with a difference of always <2 cm. CONCLUSIONS: The rate of maxillary retrusion obtained was the same if compared to other techniques. Tibial periosteal graft reduces the risk of fistula and the need for reintervention after secondary bone graft. The study did not observe negative impacts on leg growth after 25 years.

RESUMO

PURPOSE: Retromolar trigone (RMT) tumours are rare and aggressive malignancies, which require an aggressive surgical approach. The reconstruction oral cavity defects represent a challenge because of the critical role of this area both aesthetically and functionally. Free radial forearm (RF) or anterolateral thigh (ALT) flap are the first choice for the repair of intraoral defects. In reviewing the literature, there is lack of evidence pertaining to the differences between RF and ALT flaps in the reconstruction of patients with RMT tumours. This study evaluates the better microvascular reconstruction after RMT cancer resection. METHODS: Thirty patients with RMT cancer underwent oropharingectomy and microvascular reconstruction using the free RF flap (RF group) and the ALT perforator flap (ALT group). The two groups were homogeneous for sex, age, anatomic area, body mass index, and clinicopathologic profile. Viability, complications, scarring, cosmetic appearance, disorder of sensations, ROM, disease-specific items and satisfaction rate were analyzed, and statistical analysis was performed. STUDY DESIGN: Prospective study. RESULTS: There were differences between the RF and ALT groups in the morphofunctional outcomes, both short-term and long-term follow-up. These differences were statistically significant (p < 0.05) for donor site complications, cosmetic appearance, and scar evaluations. Manual dexterity was slower on the operated donor side than on the nonoperated side in the 33.3 % in the RF group. CONCLUSIONS: The study showed that the free ALT perforator flap provides better results in appearance and scarring than the RF flap for intraoral reconstruction after RMT cancer resection.

RESUMO

Sclerosing Epithelioid Fibrosarcoma (SEF) is a rare and distinct variant of low grade fibrosarcoma, found mainly in deep soft tissue of adult extremities. We report a case of Sclerosing Epithelioid Fibrosarcoma of soft tissue, which developed in a 69-year-old woman who presented a tumor involving the fourth finger of her right foot and which has not progressed much in size during the three months prior the surgical excision. Our patient is the hundredth case of Sclerosing Epithelioid Fibrosarcoma reported in literature since 1995, thus confirming the rarity of the tumor. Our experience showed that it is important to make an early diagnosis, in consideration of the clinical aggressiveness of this cancer. Another important aspect concerns the postoperative follow-up. The monitoring of PET-CT technique , although not standardized, could become part of proceedings of therapy and follow-up of tumor, thus allowing oncological radicality and avoid large amputations. To date, 24 months after diagnosis of SEF, our patient feels well, attends our outpatient clinic regularly and shows no evidence of relapse and/or metastasis.

RESUMO

BACKGROUND: Reconstruction of face deformities resulting from skin cancer includes reconstructing the area with similar tissue. This prospective study aimed to compare the functional and aesthetic outcomes between two types of local flaps (the island pedicle flap vs the bilobed flap) used in reconstruction of the ala and back nose. METHODS: In this study, 120 patients with skin cancer of the nose underwent ala and back reconstruction: 60 patients using the island flap (IF group) and 60 patients using the bilobed flap (BF group). The two groups were homogeneous for sex, age, and anatomic area. Complications, scarring according to the scale of Vancouver, cosmetic appearance, and disorders of sensations were analyzed, and statistical analysis was performed using Chi-square and analysis of variance (ANOVA). RESULTS: Early complications were more common in the BF group than in the IF group (p < 0.005). The Vancouver Scar Scale scores were significantly better for the IF patients (p < 0,005), who also showed better results in the analysis of cosmetic outcomes (p < 0.005). CONCLUSION: The study showed that the island flap used for ala and back nose reconstruction provides better functional and cosmetic results than the bilobed flap, from both functional and aesthetic points of view. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.
