Early parathyroid hormone (PTH) level as a predictor of post-surgical hypoparathyroidism.

INTRODUCTION: Post-operative hypocalcemia and postoperative persistent hypoparathyroidism remain the most common complications after thyroidectomy. Many approaches have been developed to prevent them, but actually, a common protocol is not yet individuated. MATERIALS AND METHODS: We retrospectively analyzed the results of a prospectively collected database. We dosed PTH preoperatively and 4 h after surgery (PTH_4); calcium was evaluated preoperatively, on the first (I_POD) and on the second postoperative day (II_POD). Hypocalcemia was defined when calcium <8 mg/dl. PTH_4 and I_POD calcium serum levels are identified to predict postoperative hypocalcemia. RESULTS: Three hundred and forty-eight patients were enrolled, 37 patients resulted as hypocalcemic on I_POD and 41 on the II_POD. PTH_4 is related to I_POD (p < 0.001, r = 0.45) and II_POD (p < 0.001, r = 0.44) calcemia. PTH_4-cut-off predicting I_POD hypocalcemia was 10.50 pg/ml (sensitivity: 78.7%, specificity: 72.7%). A PTH_4 value of 11.5 pg/ml is able to predict hypocalcemia during II_POD (sensitivity: 76.5%, specificity: 69.2%). We set up a combined test to predict II_POD hypocalcemia, using PTH_4 and I_POD calcium (sensitivity: 77.8%, specificity: 89.9%). CONCLUSION: This research shows the association between PTH_4 and postoperative hypocalcemia. The PTH_4 cut-off to predict I_POD-hypocalcemia was 10.5 pg/ml. We analyzed the calcemia trend during the postoperative period and we realized a combined test using PTH_4 and I_POD-calcemia. This test improves the accuracy of the previous test. Further studies, in particular multicentric, with a larger sample are necessary to validate the combined model.

Correlation between anthropometric data and preparatory maneuvers difficulties during laparoscopic right liver resections: a single center prospective study.

PURPOSE: The difficulty of laparoscopic right liver resections (LRLR) is mainly associated with their poor accessibility. Anthropometric data rather than BMI was reported to predict transection time and blood loss. Aim of the study was to evaluate the correlation between anthropometric data and preparatory manoeuvres difficulties during LRLR. METHODS: All patients who underwent LRLR requiring full right liver mobilization from November 2019 to March 2021 were prospectively included in the study. Data on surgeons' difficulty perceptions on liver mobilization (LM), isolation of right hepatic vein (RHVI), liver manageability and visibility were rated with a 5-point scale. Data on cranio-caudal liver diameters (CCliv), CHALLENGE Index (CCliv/latero-lateral abdomen diameter), times needed to LM and RHVI were collected. RESULTS: Sixty-five patients (29 wedge and 36 anatomical resections) with a median BMI of 25.5 were analysed. One patient required open conversion due to oncological reason. No correlations between BMI and CCliv or CHALLENGE Index were found. Larger CCliv diameter correlated with longer time for both RHVI (r = 0.589, p = 0.002) and LM (r = 0.222, p = 0.049). Higher CHALLENGE index correlated with longer time for RHVI (r = 0.589, p = 0.002). The CHALLENGE index showed a linear correlation with difficulty to the isolation of RHV (r = 0.327, p = 0.045), whilst the liver manipulation difficulty increased with latero-lateral liver diameter (r = 0.244, p = 0.033). BMI had no correlation with the duration of preparatory maneuvers neither with surgeons' difficulties. CONCLUSIONS: Anthropometric data can help to anticipate the difficulty of preparatory maneuvers during laparoscopic right liver resections.

Amiodarone in ventricular arrhythmias: still a valuable resource?

Ventricular arrhythmias still represent an important cause of morbidity and mortality, especially in patients with heart failure and reduced left ventricular ejection fraction. Amiodarone is a Class III Vaughan-Williams anti-arrhythmic drug widely used in ventricular arrhythmias for its efficacy and low pro-arrhythmogenic effect. On the other hand, a significant limitation in its use is represented by toxicity. In this review, the pharmacology of the drug is discussed to provide the mechanistic basis for its clinical use. Moreover, all the latest evidence on its role in different clinical settings is provided, including the prevention of sudden cardiac death, implanted cardioverter defibrillators, ischemic and non-ischemic cardiomyopathies. A special focus is placed on everyday clinical practice learning points, such as dosage, indications, and contraindications from the latest guidelines.

Effortful control is associated with executive attention: A computational study.

INTRODUCTION: Effortful control (EC) is the self-regulatory aspect of temperament that is thought to reflect the efficiency of executive attention (EA). Findings on relationship between EC and performance on EA tasks among adults are still contradictory. This study used a computational approach to clarify whether greater self-reported EC reflects better EA. METHODS: Four hundred twenty-seven healthy subjects completed the Adult Temperament Questionnaires and the Attention Network Task-revised, a conflict resolution task that gauges EA as the flanker effect (FE), that is, the difference in performances between incongruent and congruent trials. Here we also employed a drift-diffusion model in which parameters reflecting the actual decisional process (drift rate) and the extra-decisional time are extracted for congruent and incongruent trials. RESULTS: EC was not correlated with the FE computed with the classic approach, but correlated positively with drift rate for the incongruent trials, even when controlling for the drift rate in the congruent condition and the extra-decisional time in the incongruent condition. CONCLUSION: This study demonstrates an association between self-reported EC and EA among adults. Specifically, EC is not associated with overall response facilitation but specifically with a greater ability to make goal-oriented decisions when facing conflicting information.

Evidence on postoperative abdominal binding: A systematic review with meta-analysis of randomized controlled trials.

BACKGROUND: Midline laparotomy is an unavoidable approach to many surgical procedures. Many surgeons prescript the use of postoperative abdominal binder during the first mobilization after surgery. The use and the cost effective of this device is still debated by many surgeons. METHODS: PubMed, EMBASE and the CENTRAL were systematically searched for randomized controlled trials (RCT) comparing patients who wore abdominal binder ("binder") and patient who did not wear any abdominal binder ("non-binder") up to March 2020. The primary outcomes measured in the comparison were postoperative pain, pulmonary functions, the entity of physical activity, the comfort. A meta-analysis of relevant studies was performed using RevMan 5.3. RESULTS: wearing an abdominal binder after midline laparotomy seems to reduce postoperative pain on first and third postoperative day, to improve the physical activity on third postoperative day, and not affect pulmonary functions. Generally, an elastic abdominal binder is well tolerated during postoperative. CONCLUSIONS: the use of elastic abdominal binder permits a comfortable early postoperative mobilization reducing pain, increases physical activity and seems to not affect pulmonary functions.

Laparoscopic and Robotic Surgery for Splenic Artery Aneurysm: A Systematic Review.

BACKGROUND: Splenic artery aneurysms (SAAs) are the most frequent visceral aneurysms, with a life-threatening risk in case of rupture. Our systematic review investigated the features of minimally invasive surgical approaches in vascular surgery for SAAs: robotic surgery and laparoscopy. METHODS: PubMed, EMBASE, and the Web of Science were systematically searched for robotic or laparoscopic surgery reports in SAA up to January 2020. The outcomes of the study were operative time, overall morbidity, intraoperative and postoperative complications, conversion rate, and length of hospital stay. RESULTS: A total of 40 studies (29 case reports, 8 case series, 1 randomized trial, 1 video, and 1 image), including 107 patients, were considered eligible for the review. Mean operative time was 164.2 ± 75.9 min (laparoscopy), 165 min (±75.6 min) and 150 min (±87.7 min) for robotic procedures. Four cases of conversion (4.8% of all laparoscopic procedures) were reported; no conversion in the robotic series was reported. Overall morbidity was 11.2%; the most common complications were postoperative spleen infarction and pancreatitis. Medium estimated blood loss was 105.2 mL (±239.5 mL) (robotic 186.6 (±202.4) mL, laparoscopic 63 (0-270) mL). Overall length of stay was 5.43 (±5.5) days (robotic 6.1 days and laparoscopic 5.5 days). Neither mortality nor reinterventions were observed in robotic and laparoscopic series. CONCLUSIONS: In accordance with the available literature, laparoscopy and robotic surgery represent, in selected cases, a valid choice to treat SAAs. Multidisciplinary teams, comprehensive of vascular and general surgeons skilled in robotic and laparoscopic procedures, could permit to offer a tailored treatment for each patient. The rarity of this disease does not allow to perform randomized controlled trials; thus the possibility to reach definitive conclusions is currently precluded.

Personality and widowhood increase the risk for incident depression in the two years following the first acute coronary syndrome.

Objectives: Incident depression, occurring after an acute coronary syndrome (ACS) in never depressed patients, exerts a negative effect on the cardiac prognosis. Nonetheless only a few studies have evaluated the risk factor for incident depression and, particularly, no study have investigated the role of personality disorders. Therefore, the aim of this study is to verify if personality disorders represent a risk for incident depression in patients at their first ACS.Method: The study sample was selected among never depressed patients who were consecutively admitted to the Coronary Intensive Care Unit, from January 2009 to March 2012, for the first ACS. The study sample included 262 patients. The presence of depressive disorder was assessed with the Primary Care Evaluation of Mental Disorders (DSM-IV criteria), whereas its severity was evaluated with the Hospital Anxiety and Depression Scale. Evaluations were collected at baseline and at 1, 2, 4, 6, 9, 12 and 24 months of follow-up. Moreover, at baseline personality disorders were investigated with the Structured Clinical Interview for DSM-IV Axis II disorders.Results: Out of 262 subjects, a depressive disorder was diagnosed in 56 patients (21%). At baseline risk factors for incident depression were being widowed, having a distress reaction and narcissistic personality traits.Conclusion: Clinicians should keep in mind these characteristics when facing patients at their first ACS, given the detrimental effect of depression on cardiac prognosis. A psychological support should prevent the onset of incident depression in these patients.

Ruptured Superior Mesenteric Artery Aneurysm due to Fibromuscular Dysplasia: A Rare Vascular Presentation in a Patient with Schizophrenia.

Visceral aneurysms are rare entities, with a reported incidence of 0.01-2%. Fibromuscular dysplasia is a nonatherosclerotic, noninflammatory artery disease, which may predispose to aneurysmal degeneration. Schizophrenia has been linked to an increased cardiovascular risk because of the influence of traditional and disease-specific risk factors. We report the case of a 44-year-old male schizophrenic patient presenting with a ruptured giant aneurysm of superior mesenteric artery, managed by mesenteric ligation. The histologic diagnosis was fibromuscular dysplasia. Another case of visceral aneurysm in schizophrenic patient with similar histologic features has been previously reported in literature.

Temperament and Depression After a First Acute Coronary Syndrome.

Few studies assess the role of personality styles in predicting the onset of depression among cardiac patients. This study evaluates whether temperament and character can represent a risk factor for the development of incident first-ever depressive episodes in patients at their first acute coronary syndrome (ACS). Two hundred sixty-seven (72.1%) subjects (male) completed the Temperament and Character Inventory (TCI) a few days after the cardiac event. At baseline and after 1, 2, 4, 6, 9, 12, and 24 months of follow-up, the participants completed the Primary Care Evaluation of Mental Disorder (PRIME-MD) and the Hospital Anxiety and Depression Scale to establish the presence of a depressive episode and its severity. During the follow-up, 61 (22.8%) participants developed a depressive episode. Temperamental risk factors for incident depression were scored high on novelty seeking and harm avoidance at the TCI. Given the detrimental effect of depression on cardiac prognosis, clinicians should take temperament variables into account when determining the treatment plans of their patients with ACS.

The "Obsessive Paradox": The Complex Relationship Between Cognitive and Obsessive Dimensions in Schizophrenia.

The objective of the study was to investigate the relationship between cognitive functions and obsessive-compulsive dimension in schizophrenia and a possible moderating effect of schizophrenia symptom dimensions on this association. Sixty-one schizophrenia patients were administered the Positive and Negative Syndrome Scale, the Yale-Brown Obsessive-Compulsive Scale (YBOCS), and the Matrics Consensus Cognitive Battery. A U-shaped curve described a gradual transition from an inverse association to a positive relationship between YBOCS and processing speed scores, along a severity gradient of obsessive dimension. This effect ("the obsessive paradox") was not moderated by other symptom dimensions. The present study suggests that severe obsessive-compulsive symptoms may participate to counterbalance processing speed impairment independently from other symptom dimensions. These results highlight the complexity of the relationship between cognitive and obsessive dimensions in schizophrenia.

Alexithymia and Cardiac Outcome in Patients at First Acute Coronary Syndrome.

BACKGROUND: This cohort study was aimed to verify whether subjects at their first acute coronary syndrome (ACS) were more alexithymic than healthy controls (HC) and whether alexithymia can predispose patients with coronary artery disease to new major adverse cardiac events (MACE) during a 24-month follow-up period. METHODS: The sample included 100 HC with no history of depression or ACS and 304 never depressed patients with a first-ever ACS. A total of 266 patients completed the 2-year follow-up. RESULTS: Patients and HC reported similar Toronto Alexithymia Scale (TAS-20) scores. During the follow-up, 69 (22.69%) patients developed incident depression and 57 (18.75%) developed a new MACE. In a proportional hazard model, developing a first-ever depressive episode, but not alexithymia (hazard ratio = 1.008, 95% confidence interval = 0.984-1.033; p = 0.500), was associated with almost 3 times the risk of a recurrent cardiac event. CONCLUSION: Incident depression, but not TAS-20 scores, represented risk factor for MACE.

Delusional disorder: The role of personality and emotions on delusional ideation.

The relationship between personality and Delusional Disorder in still debated. The present study aimed to evaluate the role of personality features and emotional dispositions on the proneness to delusional beliefs, through the lens of a dimensional approach. 91 outpatients were administered the Structured Interview for DSM-IV Personality Disorders, the Pathological Narcissism Inventory, the Positive and Negative Affect Schedule and the Peters et al. Delusions Inventory. Delusion proneness was positively related to the "Hiding the Self" domain of narcissistic vulnerability and to paranoid traits and negatively related to "Positive Affect". Paranoid traits and "Hiding the Self" significantly interacted in influencing delusion ideation. These data suggest that proneness to delusion depends, at least in part, on a complex interplay between specific emotional and paranoid dispositions within personality.

Spontaneous Deep Femoral Artery False Aneurysm Simulating a Neoplasm: A Rare Case and Literature Review.

A 70-year-old woman presented to our attention with a painless pulsating mass at the level of the upper left thigh without any previous history of trauma, arterial surgery, or puncture of the femoral artery. Duplex ultrasound showed a nodular angiomatous-like formation with deep venous compression; computed tomographic angiography and magnetic resonance imaging reported the presence of capsulated lesion vascularized by muscular branch of deep femoral artery (DFA). The patient underwent surgical excision of a very rare thrombized DFA branch false aneurysm. Spontaneous DFA false aneurysm, although rare, will be considered in absence of trauma or vascular catheterization or previous aneurysmal rupture.

Obsessive-compulsive symptom severity in schizophrenia: a Janus Bifrons effect on functioning.

The impact of obsessive-compulsive symptoms on functioning in schizophrenia is still debated. This study investigated the relationship between OC symptoms and functioning along a severity gradient of obsessive-compulsive dimension. Sixty patients affected by schizophrenia completed the SCID-IV, the Positive and Negative Syndrome Scale, the Yale-Brown Obsessive-Compulsive Scale and the Social and Occupational Functioning Assessment Scale. The relationship between functioning and obsessive-compulsive dimension was described by a reverse U-shaped curve; functioning was positively related to the presence of mild obsessive-compulsive symptoms and inversely related to moderate and severe symptoms, after controlling for the severity of positive, negative, disorganization and general psychopathological symptoms. The role of obsessive-compulsive symptoms on social functioning in schizophrenia occurs along a severity continuum with a gradual transition from a positive correlation (from absent to mild symptoms) to an inverse correlation (for symptoms ranging from moderate to severe) and independently from schizophrenia symptom dimensions.

The role of alexithymia in predicting incident depression in patients at first acute coronary syndrome.

OBJECTIVE: Alexithymia has been considered both to predispose to depression and to worsen cardiac prognosis after an acute coronary syndrome. Nonetheless, no studies have evaluated its role as a risk factor for incident depression, in patients with acute coronary syndrome. METHODS: In 251 consecutive patients, the presence of a first-ever depressive episode was evaluated with the Primary Care Evaluation of Mental Disorders at baseline and 1, 2, 4, 6, 9, 12 and 24 months after their first acute coronary syndrome. At baseline, patients completed the Toronto Alexithymia Scale (TAS-20) and the Hospital Anxiety and Depression Scale. RESULTS: Out of 251 subjects (80.9% males), a first-ever depressive episode was diagnosed in 66 patients. Depressed and never-depressed patients differed in female gender, living status, alexithymic scores at TAS-20 and depressive symptoms. Nonetheless, nor the TAS-20 factors nor its total score were predictive of developing a depressive episode in a Cox regression. Moreover, baseline differences in TAS-20 scores between the two groups, disappeared after controlling for anhedonic symptoms. CONCLUSION: Our results do not support the hypothesis that alexithymia at TAS-20 is a risk factor for incident depression after acute coronary syndrome.

Anhedonia in schizophrenia: The role of subjective experiences.

BACKGROUND: High levels of anhedonia have been found in patients with schizophrenia; specifically they report higher levels of social anhedonia rather than physical anhedonia, and further, in the anticipatory rather than consummatory facets of pleasure. Nonetheless, contrasting results emerged regarding the underlying mechanisms of this deficit. Basic Symptoms (BS) disturb subjective experiences present for most of the illness' course; this impacts patients' daily lives leading to a loss of the ability to organize the experience of the self and the world in a fluid and automatic way. Considering the role played by negative emotions in the subjective evaluation of anhedonia, the aim of the study is to clarify the role of BS in the assessment of anhedonia in a sample of patients with schizophrenia (n=53) compared with healthy controls (n=46). METHODS: Participants completed a self-administered trait questionnaire evaluating social anhedonia (Revised-Social Anhedonia Scale), physical anhedonia (Physical Anhedonia Scale), and the consummatory and anticipatory pleasure experiences (Temporal Experience of Pleasure Scale). BS were evaluated with the Frankfurter Beschwerde-Frageboden (FBF) whereas psychopathology was assessed with the Positive and Negative Syndromes Scale. RESULTS: Patients scored higher than healthy controls in social, physical and anticipatory anhedonia, but not in consummatory anhedonia and these relationships were mediated by the FBF. Basic Symptoms of Memory, Overstimulation and Lack of Automatism were related to some facets of anhedonia, independently from depressive symptoms. CONCLUSIONS: We hypothesize that a subjective cognitive deficit and a reduced ability in information processing, could prevent patients from retaining a positive experience from past pleasant activities. Therefore the lack of pleasure would be, at least in part, related to an avoidance of potentially stressful new scenarios.

Decrease of functioning in remitted and non-remitted patients 16 years after a first-episode schizophrenia.

In schizophrenia, a better level of functioning has been generally associated with symptomatic remission. However, this association has been supported by cross-sectional studies or by studies with a short follow-up period. Forty-eight patients with schizophrenia were evaluated by the Positive and Negative Symptoms Scale and the Social and Occupational Functioning Assessment Scale (SOFAS) at the first episode and after a mean period of 16 years. At follow-up, patients were defined as remitters (R) or non-remitters (NR) according to the Remission Schizophrenia Working Group criteria. R (n = 18; 37.5%) compared to NR showed at the first episode a lower illness severity and a better level of functioning. A functional decline was found in both groups at follow-up, even though NR showed a more than twofold reduction than R. Better SOFAS scores at follow-up were predicted by baseline SOFAS score and less severe negative symptoms at follow-up. Schizophrenia implies a functional decline over time, regardless of the symptomatic remission status with negative symptoms playing a major role.

DS14 is more likely to measure depression rather than a personality disposition in patients with acute coronary syndrome.

It has been suggested that Type D Personality is a risk factor for acute coronary syndrome (ACS) and the DS14 has been developed for its assessment. However, some of the items on the DS14 seem to evaluate depressive symptoms rather than personality features. Therefore, the present study aims to verify whether an overlap exists between the constructs of Type D Personality and depression. Three-hundred-and-four consecutive patients who were both presenting their first ACS and had no history of major depression completed the Hospital Anxiety and Depression Scale (HADS) and the DS14 to assess Type D personality at baseline and have been re-evaluated at 1, 2, 4, 6, 9 and 12-month follow-ups. Out of 304 subjects (80.6% males), 40 were diagnosed as depressed. An exploratory factor analysis of HADS and the DS14 in the second month revealed that four out of seven items on the depressive subscale of HADS (HADS-D) and six out of seven items on the Negative Affectivity (NA) subscale of the DS14 segregated on the same factor. Results were verified by a Partial Confirmatory Factor Analysis performed at the twelfth month when most of the patients achieved complete remission from the depressive episode. Temporal stability was poor for NA and Type D Personality and these construct co-vary with HADS-D over time. Our data suggests that NA and depression are overlapping constructs, supporting the idea that the DS14 measures depressed features, rather than a personality disposition.
