Published: February 2020

Abstract

Background
The authors’ previous studies have found that spinal protein kinase C γ expressing neurons are involved in the feed-forward inhibitory circuit gating mechanical allodynia in the superficial dorsal horn. The authors hypothesize that nerve injury enhances the excitability of spinal protein kinase C γ expressing interneurons due to disinhibition of the feed-forward inhibitory circuit, and enables Aβ primary inputs to activate spinal protein kinase C γ expressing interneurons.

Methods

Prkcg-P2A-tdTomato mice were constructed using the clustered regularly interspaced short palindromic repeats and clustered regularly interspaced short palindromic repeats-associated nuclease 9 technology, and were used to analyze the electrophysiologic properties of spinal protein kinase C γ expressing neurons in both normal conditions and pathologic conditions induced by chronic constriction injury of the sciatic nerve. Patch-clamp whole cell recordings were used to identify the nature of the dynamic synaptic drive to protein kinase C γ expressing neurons.

Results
Aβ fiber stimulation evoked a biphasic synaptic response in 42% (31 of 73) of protein kinase C γ expressing neurons. The inhibitory components of the biphasic synaptic response were blocked by both strychnine and bicuculline in 57% (16 of 28) of neurons. Toll-like receptor 5 immunoreactive fibers made close contact with protein kinase C γ expressing neurons. After nerve injury, the percentage of neurons double-labeled for c-fos and Prkcg-P2A-tdTomato in animals walking on a rotarod was significantly higher than that in the nerve injury animals (4.1% vs. 9.9%, 22 of 539 vs. 54 of 548,P < 0.001). Aβ fiber stimulation evoked burst action potentials in 25.8% (8 of 31) of protein kinase C γ expressing neurons in control animals, while the proportion increased to 51.1% (23 of 45) in nerve injury animals (P = 0.027).

Conclusions
The Prkcg-P2A-tdTomato mice the authors constructed provide a useful tool for further analysis on how the spinal allodynia gate works. The current study indicated that nerve injury enhanced the excitability of spinal protein kinase C γ expressing interneurons due to disinhibition of the feed-forward inhibitory circuit, and enabled Aβ primary inputs to activate spinal protein kinase C γ expressing interneurons.

Prophylactic Intrathecal Morphine and Prevention of Post–Dural Puncture Headache
Authors: Peralta Feyce M. , Wong Cynthia A. , Higgins Nicole , Toledo Paloma , Jones Mary Jane , McCarthy Robert J. 
Published: February 2020

Abstract

Background
Prophylactic epidural morphine administration after unintentional dural puncture with a large-bore needle has been shown to decrease the incidence of post–dural puncture headache. The authors hypothesized that prophylactic administration of intrathecal morphine would decrease the incidence of post–dural puncture headache and/or need for epidural blood patch after unintentional dural puncture.

Methods
Parturients with an intrathecal catheter in situ after unintentional dural puncture with a 17-g Tuohy needle during intended epidural catheter placement for labor analgesia were enrolled in this randomized, double-blind trial. After delivery, subjects were randomized to receive intrathecal morphine 150 µg or normal saline. The primary outcome was the incidence of post–dural puncture headache. Secondary outcomes included onset, duration, and severity of post–dural puncture headache, the presence of cranial nerve symptoms and the type of treatment the patient received.

Results
Sixty-one women were included in the study. The incidence of post–dural puncture headache was 21 of 27 (78%) in the intrathecal morphine group and 27 of 34 (79%) in the intrathecal saline group (difference, −1%; 95% CI, −25% to 24%). There were no differences between groups in the onset, duration, or severity of headache, or presence of cranial nerve symptoms. Epidural blood patch was administered to 10 of 27 (37%) of subjects in the intrathecal morphine and 11 of 21 (52%) of the intrathecal saline group (difference 15%; 95% CI, −18% to 48%).

Conclusions
The present findings suggest that a single prophylactic intrathecal morphine dose of 150 µg administered shortly after delivery does not decrease the incidence or severity of post–dural puncture headache after unintentional dural puncture. This study does not support the clinical usefulness of prophylactic intrathecal morphine after an unintentional dural puncture.

Cervical cancer survivors’ attitudes and understanding of menopause and hormone therapy
Authors: Cotangco Katherine , Class Quetzal A. , Johnson Timothy P. , Kothari Rajul 
Published: February 2020

Abstract

Objective:
We designed a survey study to assess the presence and severity of climacteric symptoms, in addition to better understand patients’ knowledge and understanding of hormone therapy (HT).

Methods:
We administered a 23-question survey during a patient's clinic visit or over the phone. Study enrollment spanned from March, 2019 to May, 2019. The primary outcomes were severity of menopausal symptoms and willingness to try HT, calculated as a summarized overall score. Chi-square and logistic regression were used for analysis.

Results:
Our response rate was 38% (n = 34). Our participants were diverse—67% women were black and 21% women were Hispanic. Stage 1 and 2 disease was reported in 32% and 41% of women. Also, 82% and 94% of women reported ever receiving any chemotherapy or radiation therapy. There was no association between willingness to try HT for relief of menopausal symptoms and income (χ2 [1, 29] = 0.56, P = 0.81) or education level (χ2 [1, 29] = 2.78, P = 0.10). The most common climacteric symptoms experienced were hot flushes (85%) and decreased libido (77%). Neither symptom severity (odds ratio [OR] 1.31, 95% confidence interval [CI] 0.89-1.94) nor concern for side effects (OR 1.06, 95% CI 0.82-1.36) of HT significantly predicted willingness to try HT.

Conclusions:
Menopausal symptoms were prevalent in this population. Our data indicate that women are experiencing climacteric symptoms, but are overall unmotivated to address symptoms using HT. Factors such as symptom severity, fear of side effects, income level, or education level were not associated with acceptability of HT for premature menopause.

Published: February 2020

Background
This study evaluated health related quality of life and morbidity in patients who had a superiorly based partial rectus abdominis and external oblique (SPREO) flap for lower pole coverage as a component of 2-stage prosthetic breast reconstruction.

Methods
A prospective cohort study of patients undergoing immediate and delayed 2-stage breast reconstruction including a SPREO flap for lower pole coverage was conducted. The BREAST-Q and a study-specific questionnaire were used to determine outcomes after this procedure. BREAST-Q questionnaires were completed preoperatively and postoperatively and compared with normative values.

Results
BREAST-Q questionnaires were completed by 27 women. The mean patient age was 54.3 ± 9.6 years. Mean BREAST-Q scores improved significantly between preoperative and postoperative time points in Satisfaction with Breasts (preoperative 43.2 ± 26.9, postoperative 66.2 ± 19.5, P = 0.001) and Psychosocial Wellbeing (preoperative 59.4 ± 16.4 postoperative 75.5 ± 19.4, P = 0.002). Mean scores were not significantly different in the domains Physical Wellbeing Chest, Physical Wellbeing Abdomen and Sexual Wellbeing. Postoperative BREAST-Q scores were significantly higher (P < 0.05) than previously published normative scores in Satisfaction with Breasts.

Conclusions
This study reports the use of the SPREO flap for lower pole coverage in 2-stage prosthetic breast reconstruction and demonstrates that it may be a useful addition to the existing repertoire of flaps used in breast reconstruction.
Surgical Management of Medication-Related Osteonecrosis of the Jaw Patients Related to Dental Implants
Authors: Nisi Marco , Izzetti Rossana , Gennai Stefano , Bellini Pierantonio , Graziani Filippo , Gabriele Mario 
Published: February 2020

Objectives:
The aim of the present study is to report a case series of patients with peri-implant medication-related osteonecrosis of the jaw (MRONJ), in particular describing the onset of the condition and surgical treatment outcome.

Material and Methods:
Fifteen consecutive patients with clinical diagnosis of peri-implant MRONJ were retrospectively included in the study. The sample was stratified on the base of oral, pharmacological, and general health variables. The number of affected implants was recorded in all patients, and MRONJ staging applied. Surgical treatment was performed with a standardized operative protocol, involving implant removal, sequestrectomy, debridement of soft tissue, and bone curettage. Follow-up evaluating surgical outcome was performed at twelve months after surgery.

Results:
in our study sample, patients were almost equally distributed in terms of underlying diseases in osteoporotic and oncologic patients. All MRONJ lesions were symptomatic, and in 6 patients bone exposure was detected. 40 implants in total were evaluated, with MRONJ being present around 29 implants. 12 patients were diagnosed with Stage III MRONJ, and 3 patients with Stage II MRONJ. Surgical treatment leads to complete healing in 86.7% of cases, with 100% success for maxillary MRONJ.

Conclusions:
Surgical treatment seems to have a positive impact on MRONJ treatment also in cases of peri-implant involvement. However, monitoring and prevention are fundamental in patients under pharmacological treatment with anti-resorptive/antiangiogenic drugs, as peri-implant MRONJ can develop also in absence of specific traumatic events.
Internet society, internet addiction, and pathological social withdrawal: the chicken and egg dilemma for internet addiction and hikikomori
Authors: Kato Takahiro A. , Shinfuku Naotaka , Tateno Masaru 
Published: February 2020

Purpose of review
Internet society has made our daily life more convenient, while its negative consequences especially internet, smartphone, and gaming addiction are emerging. At the same time, the phenomenon of pathological social withdrawal called ‘hikikomori’ has been increasingly highlighted as a problematic behavior in Japan. Now hikikomori is becoming a global mental health issue. The interaction between internet society, internet addiction, and hikikomori has not been well clarified.

Recent findings
A case vignette survey among psychiatrists suggested that hikikomori cases could be comorbid with internet addiction. In reality, hikikomori cases with internet addiction have been reported internationally. A recent survey among college/university students in Japan has indicated positive interactions between internet addiction, smartphone addiction, gaming internet disorder, and hikikomori-tendencies.

Summary
The cause of hikikomori has not been well understood, and the emergence of internet may be one of the important contributing factors for the occurrence of hikikomori. Whether pathological social withdrawal creates internet addiction, or internet overuse creates hikikomori remains unclear. Both possibilities exist, and we herein propose the conceptual model of these hypothetical interactions. Clarifying the mechanisms of both conditions will help to solve these crucial issues for contemporary urban societies.

AbstractA respiratory illness has been spreading rapidly in China, since its outbreak in Wuhan city, Hubei province in December 2019. The illness was caused by a novel coronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Clinical manifestations related to SARS-CoV-2 infection ranged from no symptom to fatal pneumonia. World Health Organization (WHO) named the diseases associated with SARS-CoV-2 infection as COVID-19. Real time RT-PCR is the only laboratory test available till now to confirm the infection. However, the accuracy of real time RT-PCR depends on many factors, including sampling location and of methods, quality of RNA extraction and training of operators etc.. Variations in these factors might significantly lower the sensitivity of the detection. We developed a peptide-based luminescent immunoassay to detect IgG and IgM. Cut-off value of this assay was determined by the detection of 200 healthy sera and 167 sera from patients infected with other pathogens than SARS-CoV-2. To evaluate the performance of this assay, we detected IgG and IgM in the 276 sera from confirmed patients. The positive rate of IgG and IgM were 71.4% (197/276) and 57.2% (158/276) respectively. By combining with real time RT-PCR detection, this assay might help to enhance the accuracy of diagnosis of SARS-CoV-2 infection.
Applying chemical reaction transition theory to predict the latent transmission dynamics of coronavirus outbreak in China
Authors: Xu Peng 
Published: February 2020

AbstractThe recent outbreak of the Covid-19 suggests a rather long latent phase that precludes public health officials to predict the pandemic transmission on time. Here we apply mass action laws and chemical transition theory to propose a kinetic model that accounts for viral transmission dynamics at the latent phase. This model is useful for authorities to make early preventions and control measurements that stop the spread of a deadly new virus.

BackgroundA novel coronavirus (COVID-19) has emerged recently as an acute respiratory syndrome. The outbreak was originally reported in Wuhan, China, but has subsequently been spread world-widely. As the COVID-19 continues to spread rapidly across the world, computed tomography (CT) has become essentially important for fast diagnoses. Thus, it is urgent to develop an accurate computer-aided method to assist clinicians to identify COVID-19-infected patients by CT images.Materials and MethodsWe collected chest CT scans of 88 patients diagnosed with the COVID-19 from hospitals of two provinces in China, 101 patients infected with bacteria pneumonia, and 86 healthy persons for comparison and modeling. Based on the collected dataset, a deep learning-based CT diagnosis system (DeepPneumonia) was developed to identify patients with COVID-19.ResultsThe experimental results showed that our model can accurately identify the COVID-19 patients from others with an excellent AUC of 0.99 and recall (sensitivity) of 0.93. In addition, our model was capable of discriminating the COVID-19 infected patients and bacteria pneumonia-infected patients with an AUC of 0.95, recall (sensitivity) of 0.96. Moreover, our model could localize the main lesion features, especially the ground-glass opacity (GGO) that is of great help to assist doctors in diagnosis. The diagnosis for a patient could be finished in 30 seconds, and the implementation on Tianhe-2 supercompueter enables a parallel executions of thousands of tasks simultaneously. An online server is available for online diagnoses with CT images byhttp://biomed.nscc-gz.cn/server/Ncov2019.ConclusionsThe established models can achieve a rapid and accurate identification of COVID-19 in human samples, thereby allowing identification of patients.

AbstractPeriods of fasting and refeeding may reduce cardiometabolic risk elevated by Western diet. We show that in hypertensive metabolic syndrome (MetS) patients (n=35), a 5-day fast followed by a modified DASH diet (Dietary Approach to Stop Hypertension) reduced systolic blood pressure (SBP), antihypertensive medication need, and body-mass index (BMI) at three months post intervention compared to a modified DASH diet alone (n=36). Fasting altered the gut microbiome, impacting bacterial taxa and gene modules associated with short-chain fatty acid production. Cross-system analyses revealed a positive correlation of circulating mucosa-associated invariant T (MAIT) cells, non-classical monocytes and CD4+ effector T cells with SBP. Furthermore, regulatory T cells (Tregs) positively correlated with BMI and weight. Machine learning could predict sustained SBP-responsiveness within the fasting group from baseline immunome data, identifying CD8+ effector T cells, Th17 cells and Tregs as important contributors to the model. The high-resolution multi-omics data highlights fasting as a promising non-pharmacological intervention in MetS.

AbstractBackgroundThe diagnosis of Human African Trypanosomiasis (HAT) typically involves two steps: a serological screen, followed by the detection of living trypanosome parasites in the blood or lymph node aspirate. Live parasites can, however, remain undetected in some seropositive individuals, who we hypothesize are infected with Trypanosoma brucei gambiense parasites in their extravascular dermis.Methods and findingsTo test this hypothesis, we conducted a prospective observational cohort study in the gambiense HAT (gHAT) focus of Forecariah, in the Republic of Guinea. 5,417 subjects in this disease foci underwent serological screening for gHAT. Of these individuals, 66 were enrolled into our study, of whom 40 were seronegative, 8 were seropositive but unconfirmed, and 18 confirmed gHAT cases. Enrolled individuals underwent a dermatological examination, and had blood samples and skin biopsies taken and examined for trypanosomes by molecular and immuno-histological methods. In confirmed cases, dermatological symptoms were significantly more frequent, relative to seronegative controls. T. b. gambiense parasites were present in the blood of all confirmed cases but not in unconfirmed seropositive individuals. However, trypanosomes were detected in the dermis of all unconfirmed seropositive individuals and confirmed cases. After 6 and 20 months of treatment, dermal trypanosome numbers in skin biopsies of confirmed cases progressively reduced.ConclusionsOur results thus highlight the skin as a potential reservoir for trypanosomes, with implications for our understanding of this disease’s epidemiology in the context of its planned elimination and highlighting the skin as a novel target for gHAT diagnostics.

AbstractImportanceThe outbreak of highly contagious COVID-19 has posed a serious threat to human health, especially for those with underlying diseases. However, Impacts of COVID-19 epidemic on HD center and HD patients have not been reported.ObjectiveTo summery an outbreak of COVID-19 epidemic in HD center.Design, Setting, and ParticipantsWe reviewed the epidemic course from the first laboratory-confirmed case of COVID-19 infection on January 14 to the control of the epidemic on March 12 in the HD center of Renmin Hospital of Wuhan University. Total 230 HD patients and 33 medical staff were included in this studyExposuresCOVID-19.Main Outcomes and MeasuresEpidemiological, clinical, laboratory, and radiological characteristics and outcomes data were collected and analyzed. 19 COVID-19 HD patients, 19 non-COVID-19 HD patients and 19 healthy volunteers were enrolled for further study about the effect of SARS-CoV-2 infection on host immune responses.Results42 out of 230 HD patients (18.26%) and 4 out of 33 medical staffs (12.12%) were diagnosed with COVID-19 from the outbreak to March 12, 2020. 13 HD patients (5.65%), including 10 COVID-19 diagnosed, died during the epidemic. Only 2 deaths of the COVID-19 HD patients were associated with pneumonia/lung failure. Except 3 patients were admitted to ICU for severe condition (8.11%), including 2 dead, most COVID-19 diagnosed patients presented mild or none-respiratory symptoms. Multiple lymphocyte populations in HD patients were significantly decreased. HD patients with COVID-19 even displayed more remarkable reduction of serum inflammatory cytokines than other COVID-19 patients.Conclusions and RelevanceHD patients are the highly susceptible population and HD centers are high risk area during the outbreak of COVID-19 epidemic. HD Patients with COVID-19 are mostly clinical mild and unlikely progress to severe pneumonia due to the impaired cellular immune function and incapability of mounting cytokines storm. More attention should be paid to prevent cardiovascular events, which may be the collateral impacts of COVID-19 epidemic on HD patients.
