Virtual Surgical Planning for Temporomandibular Joint Reconstruction with Stock TMJ Prostheses: Pilot Study.
No full text20.500.12530/87910The temporomandibular joint (TMJ) is one of the most complex joints in the human anatomy. In advanced degenerative stages, conservative or minimally invasive surgical therapies have failed to restore joint function, and joint replacement with prostheses has been required. Stock prostheses, compared to custom-made prostheses, are much less expensive and require less pre-operative preparation time. Four patients followed for years for temporomandibular dysfunction and previously operated on by arthroscopy or open joint surgery that have been reconstructed with stock TMJ prostheses (STMJP) through virtual surgical planning (VSP) and an STL model with surgical and positioning guides were included. The median follow-up was 15 months; the median number of previous TMJ surgeries was 2. The mean preoperative MIO was 24.6 mm and at longest follow-up was 36.4 mm. The median preoperative TMJ pain score was 8, and the median postoperative TMJ pain was 3. All patients have improved their mandibular function with a clear improvement of their initial situation. In conclusion, we believe that stock TMJ prostheses with virtual surgical planning and surgical guides are a good alternative for TMJ reconstruction at the present time. Nonetheless, prospective and randomized trials are required with long-term follow up to assess their performance and safety

No full textWhat Is the Opinion of the Health Care Personnel Regarding the Use of Different Assistive Tools to Improve the Quality of Neonatal Resuscitation?
No full text It is important to determine whether the use of different quality improvement tools in neonatal resuscitation is well-received by health care teams and improves coordination and perceived quality of the stabilization of the newborn at birth. This study aimed to explore the satisfaction of personnel involved in resuscitation for infants under 32 weeks of gestational age ( A quasi-experimental, prospective, multicenter intervention study was conducted in five level III-A neonatal intensive care units in Madrid (Spain). The intervention involved conducting weekly RRSA of neonatal resuscitation stations and the systematic use of checklists, briefings, and debriefings during stabilization at birth for infants Comparison of data from 200 preintervention surveys and 155 postintervention surveys revealed statistically significant differences (p Personnel attending to infants · RRSA, checklists, briefings, and debriefings improve the quality of neonatal resuscitation at birth.. · These tools, when used together, are well-received and enhance perceived resuscitation quality.. · Perception of utility and quality improvement is consistent across roles and experience.
Lung ultrasound in neonates under cardiac surgery: feasible and predictive.
No full text20.500.12530/87910To determine whether pre- and postoperative follow-up based on lung ultrasound is associated with the respiratory and clinical evolution of patients undergoing cardiac surgery in the neonatal period. Prospective observational unicentric study from December 2020 to October 2023 in a neonatal intensive care unit, a referral center for congenital heart diseases (CHD). Neonates with CHD exposed to heart surgery or percutaneous catheterization in their first 28 days of life were included. LU follow-up was performed before surgery (LUSpre) and on days 1 (LUS_1), 3 (LUS_3), and 7 (LUS_7) afterwards by mean of a dedicated score (LUS) ranging from 0 to 3 points in 8 areas (total score 0-24). Fifty-five neonates were included. Median gestational age was 39.1 weeks (37.8-40.1), birth weight 3088 g (IQR 2910-3400). Forty-nine received surgery and 6 only percutaneous catheterization. Median LUSpre score was associated with total respiratory support in the first 30 postoperative days (p = 0.034). Median postoperative LUS was significantly higher than LUSpre in the surgery cohort at all time points (p Performance of lung ultrasound follow-up in CHD in the NICU is feasible and predictive of the respiratory evolution of the patient. LUS_1 presented the highest predictive values. The presence of consolidations is associated with a worse respiratory evolution and if they persist for a week after the procedure, it may raise suspicion of ipsilateral diaphragmatic paralysis

SEOM-GEM clinical guidelines for cutaneous melanoma (2023).
No full text20.500.12530/87858Cutaneous melanoma incidence is rising. Early diagnosis and treatment administration are key for increasing the chances of survival. For patients with locoregional advanced melanoma that can be treated with complete resection, adjuvant-and more recently neoadjuvant-with targeted therapy-BRAF and MEK inhibitors-and immunotherapy-anti-PD-1-based therapies-offer opportunities to reduce the risk of relapse and distant metastases. For patients with advanced disease not amenable to radical treatment, these treatments offer an unprecedented increase in overall survival. A group of medical oncologists from the Spanish Society of Medical Oncology (SEOM) and Spanish Multidisciplinary Melanoma Group (GEM) has designed these guidelines, based on a thorough review of the best evidence available. The following guidelines try to cover all the aspects from the diagnosis-clinical, pathological, and molecular-staging, risk stratification, adjuvant therapy, advanced disease therapy, and survivor follow-up, including special situations, such as brain metastases, refractory disease, and treatment sequencing. We aim help clinicians in the decision-making process
Human in vivo evidence of associations between herpes simplex virus and cerebral amyloid-beta load in normal aging.
No full text20.500.12530/87913Mounting data suggests that herpes simplex virus type 1 (HSV-1) is involved in the pathogenesis of AD, possibly instigating amyloid-beta (Aβ) accumulation decades before the onset of clinical symptoms. However, human in vivo evidence linking HSV-1 infection to AD pathology is lacking in normal aging, which may contribute to the elucidation of the role of HSV-1 infection as a potential AD risk factor. To shed light into this question, serum anti-HSV IgG levels were correlated with 18F-Florbetaben-PET binding to Aβ deposits and blood markers of neurodegeneration (pTau181 and neurofilament light chain) in cognitively normal older adults. Additionally, we investigated whether associations between anti-HSV IgG and AD markers were more evident in APOE4 carriers. We showed that increased anti-HSV IgG levels are associated with higher Aβ load in fronto-temporal regions of cognitively normal older adults. Remarkably, these cortical regions exhibited abnormal patterns of resting state-functional connectivity (rs-FC) only in those individuals showing the highest levels of anti-HSV IgG. We further found that positive relationships between anti-HSV IgG levels and Aβ load, particularly in the anterior cingulate cortex, are moderated by the APOE4 genotype, the strongest genetic risk factor for AD. Importantly, anti-HSV IgG levels were unrelated to either subclinical cognitive deficits or to blood markers of neurodegeneration. All together, these results suggest that HSV infection is selectively related to cortical Aβ deposition in normal aging, supporting the inclusion of cognitively normal older adults in prospective trials of antimicrobial therapy aimed at decreasing the AD risk in the aging population
Genetic and clinical characterization of a novel FH founder mutation in families with hereditary leiomyomatosis and renal cell cancer syndrome.
No full text20.500.12530/87912Hereditary leiomyomatosis and renal cell cancer syndrome is a rare autosomal dominant hereditary syndrome. Previously, we published the largest cohort of FH mutation carriers in Spain and observed a highly recurrent missense heterozygous variant, FH(NM_000143.4):c.1118A > G p.(Asn373Ser), in 104 individuals from 31 apparently unrelated families. Here, we aimed to establish its founder effect and characterize the associated clinical phenotype. Haplotype analysis confirmed that families shared a common haplotype (32/38 markers) spanning 0.61-0.82 Mb, indicating this recurrent variant was inherited from a founder ancestor. Cutaneous and uterine leiomyomatosis were diagnosed in 64.6% (64/99) and 98% (50/51) of patients, respectively, and renal cell cancer was present in 10.4% (10/96). The pathogenic FH_c.1118A > G variant is a Spanish founder mutation that originated 12-26 generations ago. We estimate that the variant may have appeared between 1370 and 1720. Individuals carrying this founder mutation had similar frequency of renal cell cancer and a higher frequency of renal cysts and leiomyomas than those in other cohorts of this syndrome. In the Spanish province of Alicante there is a high prevalence of HLRCC because of the founder mutation FH c.1118A > G; p.(Asn373Ser). The characterization of founder mutations provides accurate and specific information regarding their penetrance and expressivity. In individuals with suspected HLRCC from the province of Alicante, genetic testing by direct analysis of the founder FH c.1118A > G; p.(Asn373Ser) mutation may be a faster and more efficient diagnostic tool compared with complete gene sequencing
