Diaphragm plication (DP) improves pulmonary function and quality of life for those with diaphragm paralysis/dysfunction. It is unknown whether differing degrees of diaphragm dysfunction as measured by sniff testing impact results after plication.
Patients who underwent minimally invasive DP from 2008-2019 were dichotomized based on sniff test results paradoxical motion (PM) vs. no paradoxical motion (NPM) - the latter including normal/decreased/no motion. Preoperative and postoperative pulmonary function testing (PFT) after DP was compared between the two groups. The impact of diaphragm height index (DHI), a measure of diaphragm elevation, was also assessed.
Twenty-six patients underwent preoperative sniff testing, DP, and postoperative PFTs. Including all patients, DP resulted in a 17.8 ± 5.5% (p<0.001) improvement in forced expiratory volume at 1 second (FEV1), a 14.4 ± 5.3% (p<0.001) improvement in forced vital capacity (FVC), and a 4.7 ± 4.6% (p=0.539) improvement in diffusing capacity (DLCO). There were greater improvements in the PM group (n=16) vs. NPM group (n=10) for FEV1 (27.2 ± 6.0% vs. 3.9 ± 6.2%, p=0.017) and FVC (28.1 ± 5.3% vs. -0.5 ± 3.3%, p=0.001). There was no difference in ΔDLCO between groups. There were no differences between patients with PM and NPM in postoperative course/complications. No value for DHI predicted improvement in PFTs following DP.
Patients with PM on sniff test have dramatically greater objective improvements in pulmonary function following plication than those without PM. Most patients without PM do not demonstrate improvement in standard PFTs. Improvements in dyspnea require additional study.

The longitudinal cost of treating patients with non-small cell lung cancer (NSCLC) undergoing surgical resection has not been evaluated. We describe initial and 4-year resource use and cost for NSCLC patients ≥65 years of age treated surgically between 2008 and 2013.
Using clinical data for NSCLC resections from the Society of Thoracic Surgeons General Thoracic Surgery Database linked to Medicare claims, resource use and cost of preoperative staging, surgery and subsequent care through 4 years were examined ($2017). Cost of hospital-based care was estimated using cost-to-charge ratios; professional services and care in other settings were valued using reimbursements. Inverse probability weighting was used to account for administrative censoring. Outcomes were stratified by pathologic stage, and by surgical approach for Stage I lobectomy patients.
Resection hospitalizations averaged 6 days and cost $31,900. In the first 90 days, costs increased with stage ($12,430 Stage I to $26,350 Stage IV). Costs thenintensive care and earlier detection and treatment of disease.
The purpose of this study was to investigate the relationship between the visual characteristics of tongue lesion images obtained through intraoral ultrasonographic examination and the occurrence of late cervical lymph node metastasis in patients with tongue cancer.
This study investigated patients with primary tongue cancer who were examined using intraoral ultrasonography at Hiroshima University Hospital between January 2014 and December 2017. The inclusion criteria were squamous cell carcinoma, curative treatment administration, lateral side of tongue, surgery or brachytherapy alone, no cervical lymph node or distant metastasis as primary treatment, and treatment in our hospital. The exclusion criteria were carcinoma in situ, palliative treatment, dorsum of tongue, and multiple primary cancers. The follow-up period was more than 1year. The primary endpoint was the occurrence of late cervical lymph node metastasis, and the primary predictor variables were age, gender, longest diameter, thickness, margin node metastasis in N0 cases.
To evaluate whether the distance between the mandibular occlusal plane and mandibular foramen predicts inferior alveolar nerve (IAN) position after the sagittal split osteotomy (SSO) when using a low medial horizontal osteotomy (Posnick's modification).
This was a retrospective cohort study of patients undergoing bilateral SSOs with the medial osteotomy placed at the level of the mandibular occlusal plane. The primary predictor variable was the vertical distance between the mandibular foramen and mandibular occlusal plane. The primary outcome was IAN position after SSO contained within the proximal segment or freely entering the distal segment. Secondary predictor variables were age, gender, primary diagnosis, and type of surgery. Descriptive, bivariate, and regression statistics were computed.
Thirty-one patients underwent 62 SSOs using a low medial cut; the sample's mean age was 19.6±3.0years, and 16 subjects were female. Twenty-three subjects had a primary diagnosis of craniofacial anomaly, and 26 sual plane and mandibular foramen predicts the position of the IAN after SSO when using a low medial horizontal osteotomy.
To explore the advantages of virtual surgical planning (VSP) and traditional surgical planning (TSP) to determine whether the current VSP technique is superior to the TSP technique for orthognathic surgery.
An electronic search was carried out in the CENTRAL, PubMed, and Embase databases to identify randomized clinical trials (RCTs) that compared the VSP and TSP techniques regarding their surgical accuracy for hard tissue, prediction precision for soft tissue, required time for planning and surgery, cost and patient-reported outcomes.
Eight articles from 5 RCTs, involving 199 patients, were identified. The findings showed that the VSP and TSP techniques were similar in surgical accuracy for hard tissue in the sagittal plane, although the VSP technique was significantly more accurate in certain reference areas, especially in the anterior area of the maxilla. Both the VSP and TSP techniques had significantly better surgical accuracy for the maxilla than for the mandible. The VSP technique showed clinicalle method are recommended.
Currently, the VSP technique has become a good alternative to the TSP technique for orthognathic surgery, especially regarding frontal-esthetic considerations. Studies reporting indicators with good representativeness and sensitivity using an identical comparative method are recommended.
Computer-assisted surgery (CAS) was implemented rapidly, and recent concerns have been raised regarding its safety and its effect on surgical outcomes. We wanted to understand the impact CAS has on the surgical margin status when used for the resection of ameloblastoma.
We performed a 10-year retrospective cohort study at a single institution. Subjects were identified by surgical logs and chart query. Histopathologic reports were examined for margin status. We compared surgical technique (CAS and non-CAS) with the surgical margin (≤5mm vs >5mm). Other variable outcomes included previous treatment, histologic type, time from imaging to surgery, and recurrence. Bivariate analysis was performed to determine significance.
A total of 31 subjects were identified (12 females; 19 males) with a mean age of 34.5 (standard deviation [SD] ± 19.1) years. Fifteen subjects were included in the CAS group and 16 subjects in the non-CAS group. No statistically significant difference was identified between the CAS and non-CAS group when surgical margins were defined as less than or equal to 5mm and greater than 5mm (P=.5368). The average distance from surgical margin to lesion was 9.6mm (SD ± 5.1) in the CAS group and 8.5mm (SD ± 5.6) in the non-CAS group (P=.2590). However, the non-CAS group had 1 positive margin and a total of 6 margins of less than or equal to 2mm compared with zero margins of less than or equal to 2mm in the CAS group (closest margin 3mm).
The use of CAS and cutting guides based on predetermined surgical margins did not compromise the margin status in surgical resections of ameloblastoma. The use of CAS could potentially decrease the occurrence of close or positive margins.

Here, we examine the cross-species transmission and mammalian adaptation of this influenza A virus, revealing changes in the hemagglutinin surface protein that increase stability and receptor binding. The seal A/H10N7 virus was aerosol or respiratory droplet transmissible between ferrets. Compared with avian H10 hemagglutinin, seal H10 hemagglutinin showed stronger binding to the human-type sialic acid receptor, with preferential binding to α2,6-linked sialic acids on long extended branches. In X-ray structures, changes in the 220-loop of the receptor-binding pocket caused similar interactions with human receptor as seen for pandemic strains. Two substitutions made seal H10 hemagglutinin more stable than avian H10 hemagglutinin and similar to human hemagglutinin. Consequently, identification of avian-origin influenza viruses across mammals appears critical to detect influenza A viruses posing a major threat to humans and other mammals.Cryptosporidium emerged as a leading global cause of severe diarrheal disease in children. The parasite occupies a unique intracellular niche at the brush border of intestinal epithelial cells, where it undergoes a complex sexual life cycle. How this life cycle unfolds and how host and parasite interact remain largely to be discovered. A series of technical advances now offer genetic and immunological tools for mechanistic investigation of the parasite. Here we introduce the pathogen and disease and highlight important questions to tackle onward. We invite scientists to consider this versatile parasite model to probe the biology and immunology of the intestine.The features that permit or prevent a virus from becoming a zoonotic threat is an ongoing area of investigation. In this issue of Cell Host & Microbe, Herfst et al. and Henritzi et al. help define the molecular and host determinants of influenza virus spillover from animal to human populations.Whole-organism vaccination is a promising approach to prevent malaria. In this issue of Cell Host & Microbe, McNamara and colleagues identify epitope masking as a hindrance to antibody boosting after repeated administration of attenuated Plasmodium falciparum sporozoite vaccine.Bacterial competition within host-associated polymicrobial communities shapes their composition, often with far-reaching consequences for human health. In this issue of Cell Host & Microbe, Perault et al. reveal how competition between two opportunistic pathogens could account for the epidemiology of chronic lung infections in people with cystic fibrosis.In this issue of Cell Host & Microbe, Nielsen and colleagues sequence antibody repertoires of patients with severe COVID-19 to reveal potentially convergent features on the background of a larger, polyclonal response. Their findings suggest that, as databases improve, it may be possible to monitor virus-specific B cells after infection or vaccination using antibody sequencing.
