Humoral and Cellular Immune Response Elicited by the BNT162b2 COVID-19 Vaccine Booster in Elderly.

Although the safety and efficacy of COVID-19 vaccines in older people are critical to their success, little is known about their immunogenicity among elderly residents of long-term care facilities (LTCFs). A single-center prospective cohort study was conducted: a total IgG antibody titer, neutralizing antibodies against Wild-type, Delta Plus, and Omicron BA.2 variants and T cell response, were measured eight months after the second dose of BNT162b2 vaccine (T0) and at least 15 days after the booster (T1). Forty-nine LTCF residents, with a median age of 84.8 ± 10.6 years, were enrolled. Previous COVID-19 infection was documented in 42.9% of the subjects one year before T0. At T1, the IgG titers increased up to 10-fold. This ratio was lower in the subjects with previous COVID-19 infection. At T1, IgG levels were similar in both groups. The neutralizing activity against Omicron BA.2 was significantly lower (65%) than that measured against Wild-type and Delta Plus (90%). A significant increase of T cell-specific immune response was observed after the booster. Frailty, older age, sex, cognitive impairment, and comorbidities did not affect antibody titers or T cell response. In the elderly sample analyzed, the BNT162b2 mRNA COVID-19 vaccine produced immunogenicity regardless of frailty.

[The COVID-19 Epidemic: the experience in the Social and Health Care Center of the Mantua District (Lombardy Region, Northern Italy)]. / Epidemia di COVID-19: l'esperienza della struttura socio sanitaria territoriale provinciale di Mantova.

OBJECTIVES: to describe the course of COVID-19 epidemic in the hospitals of the ASST of Mantua (Lombrady Region, Northern Italy) from February 2020 to April 2021. DESIGN: observational study. SETTING AND PARTICIPANTS: data from hospital discharging chart of all patients admitted to the hospitals of ASST were collected from 26.02.2020 to 30.04.2021 with COVID-19 diagnosis. Data from Emergency Rooms for patients evaluated but not admitted to departments were also collected. MAIN OUTCOME MEASURES: the data from hospital discharging were crossed for diagnosis with data from laboratory. The department were classified into 'low intensity' and 'middle/high intensity'. The comparison was according to the different periods of epidemic. RESULTS: patients admitted to the hospitals were 2,738: 510 died (17.3%) and 1,736 patients were evaluated in the Emergency Rooms but not admitted to departments. Among these patients, 166 died (9.6%). The prevailing age class were >=65 years, with a trend to reduction in the third wave. The proportion of admission in middle/high intensity departments was significantly higher in the second wave than in the first. N. 510 deaths by 2,738 (17.3%) were observed, with significant reduction in the second and third waves in the low intensity departments (from 21.9% to 14.3% and 12.7%) (p<0.001), while mortality was substantially unchanged in the middle/high intensity departments (28.0%, 29.6%, and 28.3%). The mortality for patients with >=65 years was 26.7%. Females showed lower mortality (OR 0.690; CI95% 0.560-0.840) and lower incidence of admissions in middle/high intensity departments (OR 0.556; CI95% 0.459-0.673) in the three waves. Finally, including also the patients not admitted, the general mortality was 15.1%. CONCLUSIONS: a worse outcome by mortality and severity of disease was observed for male gender compared to female and for older age classes. Moreover, a significant improvement of outcomes in the second and third waves, compared to the first, was pointed out.

[Proposal of a method for assessing the risk of burnout in teachers: the VA.RI.B.O strategy]. / Proposta di un metodo per la valutazione del rischio di burnout negli insegnanti: il VA.RI.B.O (VAlutazione RIschio Burn-Out).

SUMMARY: Introduction. Burnout syndrome (BOS) can be defined as a chronic work strain characterized by three dimensions: emotional exhaustion, depersonalization (or cynicism), reduced professional effectiveness. BOS typically strikes the helping professions like the teachers. Objective. The aims of this study are: 1) clarify the concept of BOS, as currently configured in the international scientific literature; 2) analyze the psychosocial risk factors in teachers; 3) develop a methodology for the assessment and prevention of the risk of BOS in the teachers. Methods. The literature review followed some of the PRISMA guidelines criteria. Results and discussion. The results of the study highlight BOS as a risk factor specific and distinct from labor-related stress. A strategy called VA.RI.B.O is proposed (Burn-Out Recognition) for teachers.

[The Italian version of the "Claustrophobia Questionnaire": validation study and perspectives of use for the occupational physician.] / La versione italiana del "Claustrophobia Questionnaire": studio di validazione e prospettive di utilizzo per il medico del lavoro.

OBJECTIVES: Aim of our study was to adapt the Claustrophobia Questionnaire (CLQ) to the Italian context. METHODS: In our study, a sample of 50 claustrophobic patients was compared to 50 healthy people (control group). All of them answered the Claustrophobia Questionnaire and the Stait-Trait Anxiety Inventory Form Y1 and Y2, as well as demographic questions. RESULTS: As it was theoretically expected, our results confirmed the two-factor structure and showed that the Italian version of the CLQ has good psychometric properties. Indeed, it was observed that claustrophobic patients scored higher in claustrophobia than those from the control group. CONCLUSIONS: In conclusion, the Italian version of the CLQ is a reliable and valid instrument to assess claustrophobic fear.

Rapid screening for malignancy in organ donors: 15-year experience with the Verona "Alert" protocol and review of the literature.

BACKGROUND: Prevention of transmission of malignancy from donors to recipients is an aim of donor assessment. We report the most stringent interpretation of the Italian National Guidelines. METHODS: A two-step ALERT process was used: ALERT1 consisting of clinical, radiological, and laboratory tests; ALERT2, consisting of intraoperative assessment in suspicious lesions. RESULTS: Four hundred of 506 potential deceased donors entered the ALERT system. Forty-one of 400 (10%) donors were excluded due to unacceptable risk of transmission. Of the remaining 359 193 required histopathology, which excluded malignancy or determined acceptable risk in 161/193 (83%). Thirty-five malignancies were identified: 19 (54%) at ALERT1, four (11%) at ALERT2, nine (26%) picked up at ALERT1 and confirmed by ALERT2. Three (9%) were missed by ALERT and diagnosed at postmortem examination. Prostate (n=12%, 34%) and renal cell (n=7%, 20%) were the most frequent carcinomas. The majority (92%) of prostate adenocarcinomas were of low risk and donation proceeded compared to 43% of renal carcinomas. Four renal carcinomas, two breast carcinomas, and a single case of nine different malignancies excluded donation. Positive ALERT donors had statistically more malignant reports than negative ALERT donors (P=<.05). CONCLUSION: Histopathology is an essential component of the multidisciplinary assessment of donors.

Development of FT-NIR models for the simultaneous estimation of chlorophyll and nitrogen content in fresh apple (Malus domestica) leaves.

Agricultural practices determine the level of food production and, to great extent, the state of the global environment. During the last decades, the indiscriminate recourse to fertilizers as well as the nitrogen losses from land application have been recognized as serious issues of modern agriculture, globally contributing to nitrate pollution. The development of a reliable Near-Infra-Red Spectroscopy (NIRS)-based method, for the simultaneous monitoring of nitrogen and chlorophyll in fresh apple (Malus domestica) leaves, was investigated on a set of 133 samples, with the aim of estimating the nutritional and physiological status of trees, in real time, cheaply and non-destructively. By means of a FT (Fourier Transform)-NIR instrument, Partial Least Squares (PLS) regression models were developed, spanning a concentration range of 0.577%-0.817% for the total Kjeldahl nitrogen (TKN) content (R2 = 0.983; SEC = 0.012; SEP = 0.028), and of 1.534-2.372 mg/g for the total chlorophyll content (R2 = 0.941; SEC = 0.132; SEP = 0.162). Chlorophyll-a and chlorophyll-b contents were also evaluated (R2 = 0.913; SEC = 0.076; SEP = 0.101 and R2 = 0.899; SEC = 0.059; SEP = 0.101, respectively). All calibration models were validated by means of 47 independent samples. The NIR approach allows a rapid evaluation of the nitrogen and chlorophyll contents, and may represent a useful tool for determining nutritional and physiological status of plants, in order to allow a correction of nutrition programs during the season.

Laser acupuncture and auriculotherapy in postural instability--a preliminary report.

The risk of falling is rather high among elderly people. Indexes obtained through the Romberg stabilometric test on a force platform have been suggested to be correlated with the risk of falling. This work aimed to test the effectiveness of auriculopuncture and ultralow-power laserpuncture versus placebo (sham stimulation) in improving postural control in an elderly population. Balance performance was measured on a force platform before and after both forms of stimulation. Main balance parameters pointed to an average short-term improvement of about 15% 1 hour after treatment and 5-10% after an interval of 3 days. However, a few participants showed a better than 30% improvement with the same parameters. Although the sample size does not allow reliable statistical analysis, the modifications are remarkable and some differences are observed between the two kinds of stimulation. Further testing with larger sized groups and including one further group using both stimulations is suggested. Although postural instability has to be defined as multi-factorial, it is often associated with balance dysfunctions that cannot be related to vestibular or central impairments but rather to proprioceptive deficits. A significant role may be ascribed to (even subliminal) nociceptive interferences with proprioceptive inputs and to a reduced capacity for updating cortical motor control models in the case of progressively declining locomotor capabilities. The explanation tentatively put forward to account for the results observed in the present preliminary study is that laser acupuncture and auriculopuncture stimulations reduce nociceptive interference and thus improve postural control.

[Polypharmacy and psychotropic drugs as risk factors for falls in long-term care setting for elderly patients in Lombardy]. / Psicofarmaci e polifarmacoterapia come fattori di rischio per le cadute negli anziani istituzionalizzati. Uno studio trasversale in una Residenza socio assistenziale lombarda.

Aim of the study was to investigate polypharmacy and psychotropic drugs as risk factors for falls in a Long-term Care Setting for elderly patients. In a cross-sectional study we investigated the characteristics of 414 subjects: 207 fallen patients 44 (21.3%) male e 163 (78.7%) female mean age 84.16 +/- 8.3 y.o. First generation neuroleptics (OR 1.739 CI 95% 1.047-2.889), benzodiazepines (OR 2.357 CI 95% 1.5-3.702) and mood stabilizers (OR 1.889 CI 95% 1.091-3.270) were associated to falls when adjusted for age, sex and comorbidities. Polypharmacotherapy (> or = 4 drugs) was a risk factor for falls when associated to a risk medication in the daily regimen only (OR 2.157 CI 95% 1.447-3.217). What raised has to be taken into account in the prescriptive activities in a Long term Care Setting for elderly patients.

Subthreshold mania as predictor of depression during interferon treatment in HCV+ patients without current or lifetime psychiatric disorders.

BACKGROUND: Depression is considered the most frequent interferon (IFN)-alpha-induced psychiatric disorder. However, other neuropsychiatric side effects of IFN treatment, such as irritability, anxiety, and manic episodes, are reported as well. We analyzed the impact of lifetime manic-hypomanic symptoms and anxiety on the development of depression in hepatitis-C-virus-infected subjects treated with two different types of IFN-alpha. METHODS: At baseline, subjects received thorough diagnostic assessment to exclude lifetime or current psychiatric symptoms. During treatment, subjects were administered interviewer-based and self-report instruments. RESULTS: Six (12%) of 49 individuals with a negative history of psychiatric disorders developed major depression during treatment with IFN. The onset of depression was significantly associated with the presence of lifetime subthreshold manic-hypomanic symptoms. Subjects exceeding manic threshold were more likely to develop depression than those below threshold (33.3% vs. 7.5%, P=.033). CONCLUSIONS: Our data suggest that individuals treated with IFN with no past history of psychiatric disorders are more likely to develop depression if they experienced subthreshold manic-hypomanic symptoms in their lifetime. These findings derive from an exploratory study and may have important implications for the prevention of IFN-induced depression if replicated in larger studies.

Occurrence of cognitive impairment and dementia after the age of 60: a population-based study from Northern Italy.

OBJECTIVE: To evaluate the age, gender and education distribution of both cognitive impairment and dementia in the whole old age range of the elderly (from 61 years of age and over). SUBJECTS AND METHODS: The study population consisted of all subjects born in 1930 or before, living in the municipality of Faenza and Granarolo, Italy (n = 7,930). A two-phase study design was implemented, by using the Mini-Mental State Examination and Global Deterioration Scale as screening instruments. The DSM-III-R diagnostic criteria were used for the clinical diagnosis of dementia. A subject was classified as affected by cognitive impairment, no dementia (CIND) if he/she scored 2 or more standard deviations lower than the corrected mean MMSE score. RESULTS: The prevalences of dementia and CIND were 6.5 per 100 (95% CI 5.9-7.0) and 5.1 per 100 (95% CI 4.6-5.6), respectively. The prevalence of CIND was higher than that of dementia in the youngest old groups (61-74 years), both in men and women, whereas the opposite pattern was present among the older old (75+). In the older age groups, dementia prevalence increased exponentially with age, while CIND prevalence was more stable. There was not a substantial gender difference in CIND prevalence in all ages. Only in the subpopulation of higher educated subjects, women had a higher prevalence of both dementia and CIND than men. Lower educated subjects had a higher prevalence of both dementia and CIND. When compared to higher educated persons, subjects without any schooling had odds ratios of 10.9 (CI 7.0-16.7) and 16.7 (CI 11.2-25.0) for dementia and CIND, respectively. CONCLUSIONS: Cognitive impairment is very common in the younger old ages (under 70 years of age), whereas dementia becomes predominant after 75 years of age. Both conditions are strongly related to the educational level.

Psychological status at the menopausal transition: an Italian epidemiological study.

OBJECTIVES: To provide epidemiological data about psychological symptoms derived from a large Italian non-clinical sample, and to investigate the correlation with psychosocial factors. METHODS: The study design was a cross-sectional postal survey of a sample of menopausal women recruited from the General Registry Office in Ferrara's province. Four thousands and seventy-three women were sent a questionnaire designed on the basis of the Women Health Questionnaire (WHQ). Together with the WHQ, women were asked to fill out a personal file to define social status, cultural level, family's characteristics, recent menstrual cycles, gynaecological history and operations, drug's assumption, life events in the last year and lifetime depression. RESULTS: Factor analysis resulted in eight clusters of symptoms. Among psychiatric symptoms, three different clusters were identified: depressive symptoms, depressed mood with anxiety symptoms, and anxiety. The cluster "depressive symptoms" was more evident in the postmenopausal period with respect to the premenopausal one. CONCLUSION: The cluster "depressive symptoms" is significantly different in the premenopausal group with respect to the postmenopausal group, with greater levels of symptomatology in the postmenopausal group. On the contrary, the factor "depressed mood with anxiety symptoms" is present to the same extent in the pre-, peri- and postmenopausal groups. Prior depression is the most predictive variable of subsequent depression in postmenopausal women. Factors related to more pronounced depressive symptoms are number of life events, postmenopausal status, place of residence in rural areas and lower cultural level.

Sequence analysis of ADARB1 gene in patients with familial bipolar disorder.

BACKGROUND: The ADARB1 gene is located in 21q22.3 region, previously linked to familial bipolar disorder, and its product has a documented action in the editing of the pre-mRNA of glutamate receptor B subunit. Dysfunction of glutamatergic neurotransmission could play an important role in the pathophysiology of bipolar disorder (BD). Glutamate excitatory neurotransmission regulation is a possible mechanism of the initial effect of anticonvulsants in regulating mood. METHODS: To investigate the hypothesis of an involvement of ADARB1 gene in the BD, the ADARB1 cDNA has been cloned and sequenced in seven selected bipolar I disorder patients with evidence of familiarity of mood disorders. A detailed investigation of the gene nucleotide sequence in the open reading frame has been performed. RESULTS: No alteration in the sequence of the ADARB1 gene cDNA was found in any patient, except a common neutral polymorphism in three out of seven patients. CONCLUSIONS: Mutations in ADARB1 gene are not commonly associated with bipolar I disorder, therefore other genes in the 21q22 region could be associated with bipolar illness in some families, likely in the context of a multifactorial transmission model.

Different classification systems yield different dementia occurrence among nonagenarians and centenarians.

Literature data consistently show different prevalence estimates of dementia when different classification systems are used in the same population. Very few data are available for the oldest old of the elderly. We investigated the occurrence of dementia among 34 nonagenarians and centenarians according to four classification systems: the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, third edition revised (DSM-III-R) and fourth edition (DSM-IV), the World Health Organization's International Classification of Diseases, 10th revision (ICD-10), and the Cambridge Examination for Mental Disorders of the Elderly (CAMDEX). Cognitive functioning, work, social function and independence in activities of daily living were evaluated by using an extensive neuropsychological examination. The prevalence (95% CI) of dementia was the following: 47.1% (95% CI 30.3-63.8) with the DSM-III-R criteria, 41.2% (95% CI 24.6-57.7) with the DSM-IV criteria, 29.4% (95% CI 14.1-44.7) with the ICD-10 criteria and 38.2% (95% CI 21.9-54.6) with the CAMDEX. The factors that best predicted disagreement between DSM-III-R and DSM-IV were calculation impairment and the presence or absence of personality changes. DSM-III-R and ICD-10 were differentiated by the weight given to executive functions that all have to be impaired according to ICD-10, whereas progressive deterioration differentiated CAMDEX from DSM-III-R. It should be noted that although the DSM-III-R diagnoses differ by a factor of 1.6 times from the ICD-10 and 1.2 times from the CAMDEX diagnoses, we are speaking about dementia, which is very frequent in nonagenarians and centenarians. Moreover, with regard to public health, an estimation of the number of subjects who will lose their autonomy is rather more useful and informative than simple prevalence figures of dementia by itself. In this light, classification systems, such as the ICD-10, that do not include impairment of social function as a criterion for assessing dementia become less adequate.

Improving psychiatric interview skills of established GPs: evaluation of a group training course in Italy.

BACKGROUND: A number of studies have shown that the communication style of GPs has a significant impact on their ability to recognize and manage psychiatric disorders. Italian training programmes do exist, but none have been evaluated for effectiveness. METHODS: Nine established GPs participated in a training programme consisting of twelve 3-h education sessions. Each session consisted of group discussion of videotaped patient interviews selected by GPs. Case discussion followed Lesser's "problem-based approach" criteria. Efficacy of training was assessed by measuring the pre-post change in accuracy in detecting psychiatric illness and changes in the interview skills of the GPs. RESULTS: Accuracy in detection of psychiatric illness increased significantly after training. Changes were seen in the interview style after training, such as use of open-ended questions and appropriate counselling in relation to problems presented by the patient. Physicians also improved their management skills by using a more negotiatory style and providing patients with supportive feedback. The way in which physicians gave advice and information to the patients improved significantly despite the fact that GPs were not instructed about how to give information to their patients. CONCLUSIONS: Group training in problem-based interviewing utilizing video feedback is a robust, culturally transferrable model for improving the skills of established physicians. Our results suggest that training produces indirect effects that are the result of the teaching method rather than of explicit instructions. Further research is required to assess how to optimize the effect of educational interventions to ensure sustainability and maximal impact on measurable outcomes of care.

The Bologna Primary Care Liaison Service: first year evaluation.

Primary care and mental health were recently integrated by the Italian health authorities. The Bologna Primary Care Liaison Service (PCLS) is ideally suited to the Italian National Health Care System, because most primary care physicians practice individually and mental health services provide first level care. The distinctive features of the program are: 1) location within a mental health center; 2) comprehensive mental health assessment and intervention; 3) collaboration between primary care physicians and mental health services which is facilitated through committees and communication. First year results met expectations. Integrating a PCLS program within a mental health center can be a viable means of implementing national policy.

Clinical risk factors for neuroleptic malignant syndrome.

Pharmacological risk factors for neuroleptic malignant syndrome (NMS) are better defined than clinical risk factors. We examined the psychopathological status preceding the onset of NMS in 20 patients. We evaluated four key psychiatric symptoms (psychomotor agitation, catatonia, disorganization and confusion) and grouped them into definite clinical syndromes. Six patients presented with an acute and severe catatonic syndrome, with all the four key psychiatric symptoms. Twelve patients presented with an acute and severe disorganized psychotic episode, with two or three key psychiatric symptoms, but not catatonia. Our study suggests that a clinical syndrome of acute disorganization, in addition to acute catatonia, is a potential clinical risk factor for NMS. The two syndromes, which can occur in the context of different mental disorders, are related to each other as both implicate alteration in behavioural monitoring, and were, in our experience, unresponsive to neuroleptics. In conclusion, we hypothesize that the recognition of these two syndromes should reduce NMS occurrence. We recommend a judicious use of neuroleptics not only in patients with acute catatonia, but also in patients with acute disorganization.

Depression in primary care. A nationwide epidemiological survey.

BACKGROUND: Most epidemiological studies on depression in primary care are conducted at single sites, and variations in reported prevalence may depend on characteristics of health care services and other local factors. OBJECTIVES: Our aim was to investigate the prevalence of depression in primary care in Italy and its association with physical illness, disability and health care utilization. METHODS: This nationwide epidemiological study involved 191 primary care physicians (PCPs) who assessed during one index week 1896 patients aged 14 and over attending their clinics. Screening was conducted by using the General Health Questionnaire-12. Probable cases were assessed by PCPs with the WHO ICD-10 Checklist for Depression and rated for severity of physical illness. RESULTS: The prevalence of current depression ranged between 7.8 and 9.0% in the three main Italian areas, with no significant variations. A linear increase from North to South was observed for psychological distress, disability and frequency of medical consultation. Depression was associated with severe, but not with mild or moderate physical illness. Depression was also associated with disability and accounted for an increased rate of consultation. CONCLUSION: Because of the disability associated with depression and of its impact on health care utilization, guidelines and intervention strategies are needed.
