Cognitive impairment represents one of the core features of schizophrenia, involves both neurocognition and social cognition domains, and has a significant negative impact on real-world functioning. The present review provides a framework for the conceptualization and characterization of \"primary\" and \"secondary\" cognitive impairment in schizophrenia. In this conceptualization, primary cognitive impairment can be defined as a consequence of the neurobiological alterations that underlie psychopathological manifestations of the disorder, while secondary cognitive impairment can be defined as the results of a source issue that has a negative impact on cognitive performance. Sources of secondary cognitive impairment are frequent in people with schizophrenia and include several different factors, such as positive and negative symptoms, depressive symptoms, autistic symptoms, pharmacotherapy, substance abuse, metabolic syndrome, social deprivation, and sleep disorders. It can be hypothesized that secondary cognitive impairment may be improved by effectively resolving the source issue, while primary cognitive impairment may benefit from dedicated treatment. Further research is required to confirm this hypothesis, to better characterize the distinction between primary and secondary cognitive impairment in a clinical and in a neurobiological perspective, and to evaluate the impact of systematically assessing and treating secondary cognitive impairment.

OBJECTIVE: This study aims to compare the outcomes of suture-less and multiple suture closure methods on postoperative pain, swelling, and trismus, and associated complications.
METHODS: This prospective, randomized clinical trial was conducted at the Department of Oral & Maxillofacial Surgery, Goa Dental College & Hospital. Inclusion criteria encompassed subjects aged between 17 and 55 years, classified as American Society of Anaesthesiologists (ASA) I, with asymptomatic impacted third molars falling within the moderately difficult impaction range (Pederson\'s difficulty index: 5-7). Study excluded individuals classified as ASA II, III, or IV, those with known or suspected allergies to the anaesthetic solution, immunocompromised patients, and individuals taking medications that could affect healing. Pregnant or lactating females and those with a history of bleeding disorders were also excluded. Wound closure methods were compared: Group A underwent primary closure with silk sutures, while Group B had suture-less closure. Subjects were allocated to the specific groups using a simple randomization method. This involved using a lottery-based random sequence to assign each participant to either Group A or Group B. Pain intensity, facial swelling, and trismus were key outcomes. Secondary outcomes included lingual nerve sensation and postoperative complications. Demographics factors, surgical details, radiographic and perioperative data, and physiological parameters were considered. Non-parametric tests and parametric test (repeated measure ANOVA) were employed. Statistical significance was set at P < 0.05.
RESULTS: Among 101 participants, both closure techniques exhibited similar outcomes in pain, swelling, and lingual nerve function. However, suture-less closure resulted in significantly less trismus and fewer cases of delayed wound healing.
CONCLUSIONS: Suture-less method after surgical removal of third molar may reduce trismus compared to multiple sutures. While pain, swelling, and lingual nerve function management were comparable.

Secondary hemophagocytic lymphohistiocytosis (sHLH) has historically been defined as a cytokine storm syndrome (CSS) occurring in the setting of triggers leading to strong and dysregulated immunological activation, without known genetic predilection. However, recent studies have suggested that existing underlying genetic factors may synergize with particular diseases and/or environmental triggers (including infection, autoimmune/autoinflammatory disorder, certain biologic therapies, or malignant transformation), leading to sHLH. With the recent advances in genetic testing technology, more patients are examined for genetic variations in primary HLH (pHLH)-associated genes, including through whole exome and whole genome sequencing. This expanding genetic and genomic evidence has revealed HLH as a more complex phenomenon, resulting from specific immune challenges in patients with a susceptible genetic background. Rather than a simple, binary definition of pHLH and sHLH, HLH represents a spectrum of diseases, from a severe complication of common infections (EBV, influenza) to early onset familial diseases that can only be cured by transplantation.

Under the best circumstances, achieving or sustaining optimum ecological conditions in estuaries is challenging. Persistent information gaps in estuarine data make it difficult to differentiate natural variability from potential regime shifts. Long-term monitoring is critical for tracking ecological change over time. In the United States (US), many resource management programs are working at maximum capacity to address existing state and federal water quality mandates (e.g., pollutant load limits, climate impact mitigation, and fisheries management) and have little room to expand routine sampling efforts to conduct periodic ecological baseline assessments, especially at state and local scales. Alternative design, monitoring, and assessment approaches are needed to help offset the burden of addressing additional data needs to increase understanding about estuarine system resilience when existing monitoring data are sparse or spatially limited. Research presented here offers a pseudo-probabilistic approach that allows for the use of found or secondary data, such as data on hand and other acquired data, to generate statistically robust characterizations of ecological conditions in estuaries. Our approach uses a generalized pseudo-probabilistic framework to synthesize data from different contributors to inform probabilistic-like baseline assessments. The methodology relies on simple geospatial techniques and existing tools (R package functions) developed for the US Environmental Protection Agency to support ecological monitoring and assessment programs like the National Coastal Condition Assessment. Using secondary estuarine water quality data collected in the Northwest Florida (US) estuaries, demonstrations suggest that the pseudo-probabilistic approach produces estuarine condition assessment results with reasonable statistical confidence, improved spatial representativeness, and value-added information. While the pseudo-probabilistic framework is not a substitute for fully evolved monitoring, it offers a scalable alternative to bridge the gap between limitations in resource management capability and optimal monitoring strategies to track ecological baselines in estuaries over time.

Field cancerization is the phenomenon that classically describes the occurrence of multiple primary malignancies in the head and neck subsites, either synchronous or metachronous. It\'s unusual to come across synchronous primaries, that too three at a time. Here is a patient who presented to us with triple primary squamous cell carcinomas involving the floor of the mouth, base of the tongue, and glottis at the same time…….

UNASSIGNED: Little is known about the frequency and impact of the persistent headache and about the incidence of chronic daily headache (CDH) after coronavirus disease 2019 (COVID-19). The aim of this prospective cohort study was to assess the incidence, risk factors, characteristics, and impact of CDH in patients with COVID-19.
UNASSIGNED: In the first stage, 288 patients were interviewed by telephone after the acute phase of COVID-19. Subsequently, 199 patients who presented headache were reinterviewed at least one year after COVID-19. Headaches that persisted beyond the acute phase of COVID-19 for three or more months and presented frequency ≥ 45 days over the first three months were considered to be CDH.
UNASSIGNED: One hundred and twenty-three patients were included, 56% were females; median age: 50 years (25th and 75th percentile: 41;58). The headache persisted beyond the acute phase of COVID-19 in 52%, and 20.3% had CDH (95% confidence interval: 13.6-28.2). Individuals who previously had headaches and who had headaches of greater intensity during the acute phase were at higher risk of developing CDH. The group with CDH included more females, greater impact of headache, more persistence of headache beyond the 120th day of COVID-19 and less throbbing headache than did the other individuals whose headache persisted.
UNASSIGNED: Patients who had COVID-19 had a high incidence of CDH. Previous headache and greater intensity of headache were associated with higher risk of CDH.

Aortoenteric fistula (AEF) is defined as the abnormal communication between the aorta and the gastrointestinal tract. AEFs are divided into primary and secondary usually after abdominal aortic aneurysm (AAA) recovery and are a rare but quite dangerous cause of gastrointestinal bleeding that the general surgeon may face during his/her career. Secondary AEF was first described in 1953 to a 44-year-old woman 3 months after an AAA operation. This review presents the role of the surgeon in the management of secondary aortoenteric fistulas. AEFs are a rare but fatal gastrointestinal bleeding cause that the general surgeon may be asked to manage. Diagnosis requires the combination of strong clinical suspicion and the presence of a history of AAA surgery. Although a vascular surgery case, general surgeons play a role in choosing the technique of restoring the intestinal tract, which seems to be significantly related to subsequent morbidity and mortality.

Background: Cervical esophageal reconstruction is vital to improve the quality of life in cancer surgery patients. Microsurgery is crucial in providing vascularized tissue for defect repair, particularly in secondary cases with a higher risk of failure due to larger defects and damage from previous surgery and radiotherapy. The purpose of this study was to describe the clinical characteristics of a series of patients who underwent secondary repair of esophageal defects and provide practical information for the management and treatment of such cases based on the authors\' experience and the literature review. Methods: We retrospectively reviewed the electronic medical records of the Plastic Surgery Clinic at the University of Trieste to identify cases of patients who underwent secondary esophageal microsurgical reconstructions following oncological surgery. Patient demographics, the etiology of esophageal defects, previous surgical history, and preoperative assessments were collected from medical records. Surgical techniques utilized for reconstruction, such as pedicled flaps or free tissue transfers, were documented along with intraoperative information. Postoperative outcomes, including complications, graft viability, and functional outcomes, were evaluated during follow-up. Results: We treated 13 cases of secondary esophageal reconstructions between 2011 and 2022. Most commonly, Antero-Lateral Thigh (ALT) flaps were used in 10 cases, while 2 cases employed a radial forearm flap (RFF), and 1 case employed a chimeric parascapular flap. No flap failures occurred during a median 50-month follow-up. One ALT flap patient experienced postop stricture but maintained swallowing ability. A single tracheoesophageal fistula occurred in an RFF patient with a history of radiotherapy and complete lymph node dissection. Conclusions: Cervical esophageal reconstruction significantly impacts patients\' quality of life by restoring oral feeding and phonation. When local flaps fall short, microsurgical reconstruction with intestinal flaps is valuable but is burdened by limitations. For challenging secondary cases, ALT or RFF flaps emerge as safer options due to their robust pedicles, yielding low complication rates and positive functional outcomes.

UNASSIGNED: Managing central venous catheters in patients with neoplasms is challenging, and peripherally inserted central catheter PORT (PICC-PORT) has emerged as a promising option for safety and efficacy. However, understanding the clinical progression of catheter-related thrombosis (CRT) in cancer patients with central venous catheters remains limited, especially in certain neoplasm types associated with a higher risk of venous thrombosis.
UNASSIGNED: This study aims to assess the effectiveness of ultrasound-guided management in detecting and treating asymptomatic CRT in cancer patients with PICC.
UNASSIGNED: In this prospective cohort study of 120 patients with solid neoplasms receiving chemotherapy, we investigated the incidence of isolated upper-extremity superficial vein thrombosis, upper-extremity deep vein thrombosis, and fibrin sheath formation through ultrasound follow-up at 30 and 90 days after catheter insertion. We analyzed risk factors associated with CRT and compared incidence rates between PICC-PORT and traditional PICC.
UNASSIGNED: Among the cohort, 69 patients (57.5%) had high-risk thromboembolic neoplasm, and 31 cases (25.8%) of CRT were observed, mostly within 30 days, with only 7 cases (22.6%) showing symptoms. Traditional PICC use (odds ratio, 5.86; 95% CI, 1.14-30) and high-risk thromboembolic neoplasm (odds ratio, 4.46; 95% CI, 1.26-15.81) were identified as independent risk factors for CRT.
UNASSIGNED: The majority of CRT present asymptomatically within the first 30 days of venous catheter insertion in patients with solid neoplasms. Ultrasound follow-up is valuable for detecting asymptomatic CRT. The risk of CRT was lower with PICC-PORT than with PICC. Additionally, the risk of CRT was found to be higher in patients with high-risk thromboembolic neoplasms. It is crucial for larger studies to confirm the utility of treating asymptomatic thromboses and isolated superficial thrombosis.

Headache affects around half of patients in the acute phase of COVID-19 and generally occurs at the beginning of the symptomatic phase, has an insidious onset, and is bilateral, and of moderate to severe intensity. COVID-19 may also present complications that cause acute and persistent headaches, such as cerebrovascular diseases, rhinosinusitis, meningitis, and intracranial hypertension. In 10% to 20% of patients with COVID-19, headache may persist beyond the acute phase. In general, the headache improves over time. To date, there are no clinical trials that have assessed the treatment of persistent post-COVID-19 headache.
