Intrusive luxation in primary dentition: clinical report
Intrusive dislocation is the most frequent type of traumatic injury in the primary dentition, characterized by displacement of the tooth into the alveolus. Intrusions require a thorough physical examination, radiographs of diagnostic value, and follow-up of the case, since the prognosis is unfavorable, mainly due to the probability of damage to the permanent tooth germ. This work aims to report a clinical case of intrusive dislocation in the primary dentition, from diagnosis to follow-up. This is a male patient, 3 years old, who attended the Emergency of the Children’s Specialty Clinic – State University of Londrina (UEL) due to dento-alveolar trauma in the antero-superior region that occurred three days ago. On clinical examination, tooth 61 had grade II intrusion (one-third of the crown visible), and tooth 62 had grade I intrusion, with more than one-third of the crown visible. Radiographically, a buccal inclination was observed, with no fracture of the bone plate. Thus, we opted for conservative treatment, waiting for the spontaneous re-eruption of the teeth involved. Furthermore, parents were informed about the possible consequences of this type of trauma and the need for clinical and radiographic follow-up consultations. After eight months of follow-up, the teeth erupted satisfactorily. It is extremely important to establish a protocol for observation and control of the traumatized tooth, observing signs and symptoms of the tissues involved in the trauma to reduce sequelae in both dentitions
Dissecting molecular mechanisms of resistance to NOTCH1-targeted therapy in T-cell acute lymphoblastic leukemia xenografts
Despite substantial progress in treatment of T-cell acute lymphoblastic leukemia (T-ALL), mortality remains relatively high, mainly due to primary or acquired resistance to chemotherapy. Further improvements in survival demand better understanding of T-ALL biology and development of new therapeutic strategies. The Notch pathway has been involved in the pathogenesis of this disease and various therapeutic strategies are currently under development, including selective targeting of NOTCH receptors by inhibitory antibodies. We previously demonstrated that the NOTCH1-specific neutralizing antibody OMP52M51 prolongs survival in TALL patient-derived xenografts bearing NOTCH1/FBW7 mutations. However, acquired resistance to OMP52M51 eventually developed and we used patient-derived xenografts models to investigate this phenomenon. Multi-level molecular characterization of T-ALL cells resistant to NOTCH1 blockade and serial transplantation experiments uncovered heterogeneous types of resistance, not previously reported with other Notch inhibitors. In one model, resistance appeared after 156 days of treatment, it was stable and associated with loss of Notch inhibition, reduced mutational load and acquired NOTCH1 mutations potentially affecting the stability of the heterodimerization domain. Conversely, in another model resistance developed after only 43 days of treatment despite persistent down-regulation of Notch signaling and it was accompanied by modulation of lipid metabolism and reduced surface expression of NOTCH1. Our findings shed light on heterogeneous mechanisms adopted by the tumor to evade NOTCH1 blockade and support clinical implementation of antibody-based target therapy for Notch-addicted tumors
O EFEITO DA REALIDADE VIRTUAL NA CAPACIDADE FUNCIONAL DE MEMBROS SUPERIORES EM INDIVÍDUOS COM HEMIPARESIA
Stroke may lead to total and/or partial loss of normal function in one of the upper limbs, and the rehabilitation is one of the main focuses of physiotherapists. The objective was to analyze the effects of virtual reality on upper limb functional capacity in individuals with hemiparesis. Initially they were evaluated for manual dexterity by the Nine Hole Peg Test (NHPT) and Box and Blocks Test (BBT) then be conducted to perform a 16-session protocol using virtual reality game through Nintendo WiiTM console. ™. We included 10 individuals with mean age of 64.5±9.54 and did not demonstrated significant results when comparing the moments, only a small effect (d=0.23) was found in the left upper limb in the NHPT. It was concluded, there was no significant improvement in the functional capacity of the upper limbs using virtual reality in individuals with hemiparesis.O acidente vascular encefálico (AVE) pode acarretar a perda total e/ou parcial da função de um dos membros superiores, sendo sua reabilitação um dos focos principais dos fisioterapeutas. O objetivo foi console Nintendo Wii™. Foram incluídos 10 participantes no estudo com idade média de 64,5±9,54 não tendo demonstrado resultados significativos quando comparado os momentos, apenas um pequeno efeito (d=0,23) foi encontrado em membro superior esquerdo no NHPT. Conclui-se então que não houve melhora significativa na capacidade funcional de membros superiores utilizando realidade virtual em indivíduos com hemiparesia
EFEITO DA TERAPIA COM REALIDADE VIRTUAL NO EQUILÍBRIO DINÂMICO DE INDIVÍDUOS PÓS-ACIDENTE VASCULAR ENCEFÁLICO
The aim of this study was to analyze the effect of virtual reality-based (VR) therapy on balance training of patients after stroke. 10 hemiparetic participants received twelve individual physical therapy sessions using the VR therapeutic, through Nintendo Wii® Fit Plus and Wii Sports Resort™. The analysis revealed that the Dynamic Gait Index (DGI) instrument, responsible for evaluating the dynamic balance, obtained significant difference (p=0.0085) between the basal (17.30±3.59) and final (20.30±2.94) evaluation. The Penguin Slide game had no significance between the scores (p=0.918), but there was a moderate correlation between the DGI instrument (r=0.662; p=0.037). This study obtained favorable results related to dynamic balance and also suggests that VR therapy as in general influenced the improvement of dynamic balance in individuals with hemiparesis after stroke.O objetivo desse estudo foi analisar o efeito da terapia com Realidade Virtual (RV) no equilíbrio dinâmico de indivíduos pós Acidente Vascular Encefálico (AVE). Participaram dez indivíduos com hemiparesia, que receberam doze sessões individuais de fisioterapia com utilização da modalidade terapêutica RV, por meio do Nintendo Wii® Fit Plus e o Wii Sports Resort™. A análise revelou que o instrumento Dynamic Gait Index (DGI), responsável por avaliar o equilíbrio dinâmico, obteve diferença significativa (p=0,0085) entre a avaliação inicial (17,30±3,59) e final (20,30±2,94). O jogo Penguin Slide não obteve significância entre as pontuações (p=0,918), mas houve uma correlação moderada entre o instrumento DGI (r=0,662; p=0,037). Esse estudo obteve resultados favoráveis relacionados ao equilíbrio dinâmico e também sugere que a terapia com RV como um todo influenciou a melhora do equilíbrio dinâmico dos indivíduos com hemiparesia pós AVE
Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy
IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical
attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced
colorectal cancers at diagnosis.
OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced
oncologic stage and change in clinical presentation for patients with colorectal cancer.
DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all
17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December
31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period),
in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was
30 days from surgery.
EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery,
palliative procedures, and atypical or segmental resections.
MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer
at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as
cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding,
lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery,
and palliative surgery. The independent association between the pandemic period and the outcomes
was assessed using multivariate random-effects logistic regression, with hospital as the cluster
variable.
RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years)
underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142
(56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was
significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR],
1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic
lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03).
CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the
SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients
undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for
these patients
Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey
Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
