Contraception and reproductive planning during the COVID-19 pandemic

ABSTRACT Introduction The coronavirus disease (COVID-19) is a global health emergency. Major disruption to healthcare services during the current COVID-19 pandemic will last even after its peak. Sexual and reproductive health (SRH), specially contraception, needs to be understood as an essential service. Areas covered This paper is a narrative review. Data from PubMed/MEDLINE, Scopus, and websites of scientific societies were screened during the months of April and May 2020. It addresses the main aspects related to contraception during the COVID-19 pandemic, with special emphasis on family planning services, extended use of long-acting reversible contraceptive (LARC) methods, drug interactions, and thromboembolism risk. We also specified some issues focused on the Brazilian reality. Expert opinion Ensuring proper contraception use in the COVID-19 time is very important. We encourage women, healthcare providers, policymakers, and the society to consider SRH services as priority.
How Well do Offline and Online Evaluation Metrics Measure User Satisfaction in Web Image Search?

Comparing to general Web search engines, image search engines present search results differently, with two-dimensional visual image panel for users to scroll and browse quickly. These differences in result presentation can significantly impact the way that users interact with search engines, and therefore affect existing methods of search evaluation. Although different evaluation metrics have been thoroughly studied in the general Web search environment, how those offline and online metrics reflect user satisfaction in the context of image search is an open question. To shed light on this, we conduct a laboratory user study that collects both explicit user satisfaction feedbacks as well as user behavior signals such as clicks. Based on the combination of both externally assessed topical relevance and image quality judgments, offline image search metrics can be better correlated with user satisfaction than merely using topical relevance. We also demonstrate that existing offline Web search metrics can be adapted to evaluate on a two-dimensional presentation for image search. With respect to online metrics, we find that those based on image click information significantly outperform offline metrics. To our knowledge, our work is the first to thoroughly establish the relationship between different measures and user satisfaction in image search.
Asymmetries during repeated treadmill sprints in elite female Rugby Sevens players

ABSTRACT This study describes asymmetry in the main running mechanical variables during repeated treadmill sprints in elite female athletes and examines whether inter-limb differences in sprinting mechanics increase with fatigue. Eighteen elite female players (French national Rugby Sevens team) performed 8 × 5-s sprints (25-s rest) on an instrumented motorised sprint treadmill. The group mean ‘symmetry angle’ (SA) scores were ~1–2% for contact time (1.6 ± 0.6%), aerial time (2.1 ± 0.8%), step frequency (1.3 ± 0.5%) and step length (1.6 ± 0.6%). Mean vertical and horizontal forces, vertical and leg stiffness presented SA values of 1.7 ± 1.5%, 2.4 ± 1.2%, 2.6 ± 0.2% and 2.5 ± 0.2%, respectively. The SA scores were ~2–8% for duration of braking (6.9 ± 5.0%) and propulsive (6.5 ± 4.4%) phases, peak braking (6.5 ± 2.5%) and propulsive (1.6 ± 0.9%) forces as well as net (5.8 ± 5.6%), braking (7.7 ± 5.3%) and propulsive (2.7 ± 1.6%) impulses. However, there was no influence of sprint repetition number on SA scores for tested variables (P > 0.05). In elite female Rugby Sevens players, there was no noticeable difference in asymmetries for the great majority of stride mechanical variables during repeated treadmill sprints.
Rosai-Dorfman disease: earlier spontaneous regression of skin lesions relative to nasal, pharyngeal, and bone lesions

Rosai-Dorfman disease (RDD) is an uncommon benign histiocytic proliferative disorder characterized by massive bilateral cervical lymphadenopathy [1]. More than 40% of RDD patients have extranodal lesions in locations such as the skin, orbit, respiratory tract and bones [2]. Of these extranodal lesions, cutaneous lesions are the commonest. We report an RDD patient with subcutaneous, nasal, pharyngeal and fibular lesions. Notably, the subcutaneous lesions showed spontaneous regression, whereas the other extranodal lesions persisted. A 37-year-old woman presented at our outpatient clinic with a month-long history of bilateral lymphadenopathy of the neck and multiple subcutaneous nodules of the limbs (figure 1A, B). Her personal and family history was unremarkable. She reported recurrent fever over two months, nasal obstruction and left ankle pain for six months. 18F-fluorodeoxyglucose PET-CT revealed multiple lesions on the limbs and cervical lymph nodes (figure 1C). Masses were also found in the nasal cavity, pharynx and fibula (figure 1D-F). The nasal and fibular lesions were accompanied by osteolytic changes. Blood tests demonstrated hypochromic anaemia and hypergammaglobulinaemia. A biopsy specimen from a subcutaneous nodule revealed numerous large histiocytic cells with a pale cytoplasm and hypochromatic nuclei in the hypodermis. Prominent emperipolesis (engulfment of lymphocytes) was also observed (figure 1G, H). These histiocytes were positive for CD68 and S100, and negative for CD1a. IgG4+ plasma cells were not found. A biopsy specimen taken from a nasal lesion showed similar pathological findings. Based
Machine learning-based analyses support the existence of species complexes for Strongyloides fuelleborni and Strongyloides stercoralis

Abstract Human strongyloidiasis is a serious disease mostly attributable to Strongyloides stercoralis and to a lesser extent Strongyloides fuelleborni, a parasite mainly of non-human primates. The role of animals as reservoirs of human-infecting Strongyloides is ill-defined, and whether dogs are a source of human infection is debated. Published multi-locus sequence typing (MLST) studies attempt to elucidate relationships between Strongyloides genotypes, hosts, and distributions, but typically examine relatively few worms, making it difficult to identify population-level trends. Combining MLST data from multiple studies is often impractical because they examine different combinations of loci, eliminating phylogeny as a means of examining these data collectively unless hundreds of specimens are excluded. A recently-described machine learning approach that facilitates clustering of MLST data may offer a solution, even for datasets that include specimens sequenced at different combinations of loci. By clustering various MLST datasets as one using this procedure, we sought to uncover associations among genotype, geography, and hosts that remained elusive when examining datasets individually. Multiple datasets comprising hundreds of S. stercoralis and S. fuelleborni individuals were combined and clustered. Our results suggest that the commonly proposed ‘two lineage’ population structure of S. stercoralis (where lineage A infects humans and dogs, lineage B only dogs) is an over-simplification. Instead, S. stercoralis seemingly represents a species complex, including two distinct populations over-represented in dogs, and other populations vastly more common in humans. A distinction between African and Asian S. fuelleborni is also supported here, emphasizing the need for further resolving these taxonomic relationships through modern investigations.
Prevalence of high‐risk human papillomavirus after HPV‐vaccination in Denmark

Vaccination against human papillomavirus (HPV) has been introduced as a public health initiative in many countries, including Denmark since October 2008. It is important to monitor postimplementation effectiveness of HPV‐vaccination at the population‐level. We studied HPV‐prevalence after first invitation to screening at age 23 years in women offered the quadrivalent HPV‐vaccine at the age of 14 years. Randomly selected screening samples from women born in 1994 in four out of five Danish regions were subjected to analysis for HPV in addition to routine cytology. Cobas4800 was used in all participating pathology departments. Data from a Danish prevaccination cross‐sectional study using Hybrid Capture 2, and a Danish split‐sample study using Cobas4800 were used for comparison. In the period from February 2017 to April 2019, 6233 screening samples from women born in 1994 were selected for HPV‐analysis; 27 samples had no HPV‐test and 3 samples had no HPV‐diagnosis, leaving 6203 samples with an HPV‐diagnosis. Prevalence of any high‐risk (HR) HPV was 35%; only 0.9% were positive for vaccine HPV types 16/18 while the remaining 34% were positive for other HR HPV. When comparing with prevaccination prevalence data, HPV‐16/18 decreased by 95%; RR = 0.05 (95% CI 0.04‐0.06), while other HR HPV remained fairly constant; RR = 0.88 (95% CI 0.82‐0.94) and RR = 0.95 (95% CI 0.88‐1.03), respectively. One‐third of women vaccinated as girls with the quadrivalent HPV‐vaccine were HR HPV‐positive at time of first invitation to screening. Vaccine HPV‐types 16 and 18 were almost eliminated, while the prevalence of nonvaccine HR HPV‐types remained constant.
Do Temporal Regularities during Maintenance Benefit Short-term Memory in the Elderly? Inhibition Capacities Matter

ABSTRACT Background/Study context Recent research has shown a benefit of temporally regular structure presented during the maintenance period in short-term memory for young adults. Because maintenance is impaired in aging, we investigated whether older adults can also benefit from the temporal regularities for maintenance and how their cognitive capacities might affect this potential benefit. Methods Healthy older adults (range: 63–90 years old) had to memorize visually presented letters and maintain them in short-term memory for 6 s until recall. The six-second retention interval was either filled with an isochronous rhythmic sound sequence that provided a temporally regular structure or silent. Results The effect of the isochronous rhythm on recall performance was modulated by inhibition capacities of older adults: as compared to silence, improved recall performance thanks to the rhythm emerged with increased inhibitory capacity of the participants. Conclusion Even though maintenance of older adults benefits less from the presence of temporal regularities than does the maintenance of younger ones, our findings provide evidence for improved maintenance in short-term memory for older adults in the presence of a temporally regular structure, probably due to enhanced attentional refreshing. It further provides perspectives for training and rehabilitation of age-related working memory deficits.
Masseter-to-Facial Cranial Nerve Anastomosis: A Report of 30 Cases.

BACKGROUND Facial nerve paralysis (FP) is a possible complication of cerebellopontine angle tumor surgery. Several donor nerves have been used in the past for facial reanimation. We report the results of 30 cases of masseter-to-facial anastomosis. OBJECTIVE To prospectively evaluate the efficacy of V to VII anastomosis after FP. METHODS In a prospective study, we included 30 consecutive patients with FP (20 women and 10 men) whose mean age was 48.8 yr (32-76 yr). In almost all cases, FP developed after cerebellopontine angle tumor surgery (29 patients), whereas in one case, FP occurred after skull base trauma. Pre- and postoperative evaluation of facial nerve function was performed using the House-Brackmann (HB) scale and the Sokolovsky scale, as well as by electromyography. Follow-up ranged from 11 to 51 mo and averaged 22 mo. RESULTS All patients achieved functional recovery of the facial nerve from VI to either III or IV HB degree. Patients with short time FP showed significantly better postoperative recovery. CONCLUSION The results of the V to VII anastomosis demonstrate a significant improvement of facial nerve function and virtually no complications.
Finite element models can reproduce the effect of nucleotomy on the multi-axial compliance of human intervertebral discs

Abstract Finite element (FE) models can unravel the link between intervertebral disc (IVD) degeneration and its mechanical behaviour. Nucleotomy may provide the data required for model verification. Three human IVDs were scanned with MRI and tested in multiple loading scenarios, prior and post nucleotomy. The resulting data was used to generate, calibrate, and verify the FE models. Nucleotomy increased the experimental range of motion by 26%, a result reproduced by the FE simulation within a 5% error. This work demonstrates the ability of FE models to reproduce the mechanical compliance of human IVDs prior and post nucleotomy.
Effects of Visual and Aural Presentation Styles and Rhythm on Working Memory as Measured by Monosyllabic Sequential Digit Recall

Although information is frequently paired with music to enhance recall, there is a lack of basic research investigating how aspects of recorded music, as well as how it is presented, facilitate working memory. Therefore, the purpose of this study was to determine the effects of visual and aural presentation styles, rhythm, and participant major on working memory as measured by sequential monosyllabic digit recall performance. We isolated visual and aural presentation styles and rhythm conditions during six different treatment stimuli presented on a computer screen in the study: (a) Visual Rhythm; (b) Visual No Rhythm; (c) Aural Rhythm; (d) Aural No Rhythm; (e) Visual + Aural Rhythm; (f) Visual + Aural No Rhythm. Participants’ (N = 60; 30 nonmusic majors and 30 music majors) task was to immediately recall the information paired with music within each condition. Analyses of variance indicated a significant difference between the visual and visual + aural presentation style conditions with the visual + aural condition having more accurate recall. While descriptive data indicated that rhythm tended to facilitate recall, there was no significant difference between rhythm and no rhythm conditions. Nonmusic major participants tended to have slightly more accurate recall than music major participants, although this difference was not significant. Participants tended to have higher recall accuracy during primacy and recency serial positions. As participants had most accurate recall during the visual + aural presentation style conditions, it seems that the multi-sensory presentation modes can be effective for teaching information to be immediately recalled as long as they do not contain too much information and overload the limited storage capacity of working memory. Implications for clinical practice, limitations, and suggestions for future research are provided.
The Applicability of a Checklist for the Diagnosis and Treatment of Exocrine Pancreatic Insufficiency

Objective To evaluate a rapid checklist capable of identifying exocrine pancreatic insufficiency in outpatients. Methods Prospective observational study of a multicenter cohort. Results One hundred and two patients were enrolled; 61.8% of the patients had medically-treated benign or malignant pancreatic disease, and 38.2% had a pancreatic resection. Visual examination of the feces was evaluated in 84 patients and it was related to steatorrhea in 51 patients (50.0%). Receiver operating characteristic curves were evaluated for each symptom or clinical sign and four of them (ie, increase in daily bowel movements, number of bowel movements, fatty stools, >10% weight loss) had a satisfactory area under the curve. At multivariate analysis, fatty stools and >10% weight loss entered into this analysis having an area under the curve of 0.916 (95% confidence interval, 0.851–0.981). At 1 month and at one year of follow-up, the pancreatic enzyme replacement therapy administered showed that pancreatic extracts were able to significantly improve the increase in daily bowel movements, the number of bowel movements, fatty and bulky stools and >10% weight loss. Conclusion Both fatty stools and >10% weight loss were able to clinically evaluate steatorrhea, and their improvement was sufficient to evaluate substitution therapy.
Evolving insights into the mechanisms of toxicity associated with immune checkpoint inhibitor therapy

Immune checkpoint inhibitors have emerged as a revolutionary treatment option for patients with various types of malignancy. Although these agents afford a significant improvement in outcomes for melanoma and other previously untreatable malignancies, their novel mechanism of action may predispose patients to immune‐related adverse effects (irAEs). In the tumour neoantigen environment, these irAEs are due to the activation of the immune system by the blockade of suppressive checkpoints, leading to increases in T‐cell activation and proliferation. IrAEs have been reported in almost any organ and at any point in time, even months to years after discontinuation of therapy. Certain populations with distinct physiological changes, genetic risk factors, and specific antigen exposures may be more highly predisposed to develop irAEs. This review discusses the incidence and mechanisms of irAEs and the relationship between host factors and irAE occurrence.
Transient stimulation of TRPV4‐expressing keratinocytes promotes hair follicle regeneration in mice

Hair follicle telogen to anagen transition results in a break in cellular quiescence of the hair follicle stem cells, which subsequently promotes hair follicle regeneration. Many critical molecules and signalling pathways are involved in hair follicle cycle progression. Transient receptor potential vanilloid 4 (TRPV4) is a polymodal sensory transducer that regulates various cutaneous functions under both normal and disease conditions. However, the role of TRPV4 in hair follicle regeneration in vivo remains incompletely understood.
Moody and thin-skinned? The interplay of neuroticism and momentary affect in older romantic couples.

Neuroticism is associated with heightened reactivity to social stressors. However, little is known about the micro-processes through which neuroticism shapes - and is shaped by - affective experiences in close relationships. We examine the extent to which momentary affect is coupled with one's relationship partner, whether the strength of this coupling differs depending on levels of neuroticism, and whether this coupling and partner's overall level of positive or negative affect prospectively contribute to differential (rank-order) changes in neuroticism. Older couples (N = 82, aged 67-93 years) rated their momentary affect six times per day for one week and provided ratings of trait neuroticism at baseline and 18 months later. Multilevel models revealed that among individuals high in neuroticism, individual positive affect was more closely coupled with partner positive affect compared with individuals low in neuroticism. Moreover, neuroticism decreased over time in those participants who showed a higher degree of coupling with partner positive affect and also had a partner with higher overall positive affect. In contrast, neuroticism increased in individuals whose partner had lower overall positive affect. Similar effects were not observed for negative affect. Our findings highlight how relationship partners contribute to daily affective experiences and longer-term changes in neuroticism.
Age-Related Morbidity and Mortality among Patients with COVID-19

On March 11, 2020, the World Health Organization declared coronavirus disease (COVID-19), caused by the novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a pandemic. During the COVID-19 pandemic, an age-associated vulnerability in the burden of disease has been uncovered. Understanding the spectrum of illness and the pathogenic mechanism of the disease in a vulnerable population is critical, especially during the pandemic. Herein, we reviewed published COVID-19 epidemiology data from several countries to identify any consistent trends in the relationship between age and COVID-19-associated morbidity or mortality. We also reviewed the literature for studies explaining the difference in the host response to SARS-CoV-2 infection according to age. The insights from these data will be useful in determining the treatment policies and preventive measures of COVID-19.
Suppression of type 2 diabetes mellitus-induced aortic ultrastructural alterations in rats by insulin: an association of vascular injury biomarkers

ABSTRACT Diabetes represents a major public health problem and an estimated 70% of people with diabetes die of cardiovascular complications. The protective effect of insulin treatment against ultrastructural damage to the tunica intima and tunica media of the aorta induced by type 2 diabetes mellitus (T2DM) has not been investigated before using transmission electron microscopy (TEM). Therefore, we induced T2DM in rats using high fat diet and streptozotocin (50 mg/kg) and administered insulin daily by i.v injection for 8 weeks to the treatment group. Whereas, the T2DM control group were left untreated for the duration of the experiment. A comparison was also made between the effect of insulin on aortic tissue and the blood level of biomarkers of vascular injury, inflammation, and oxidative stress. T2DM induced profound ultrastructural damage to the aortic endothelium and vascular smooth muscle cells, which were substantially protected with insulin. Furthermore, insulin returned blood sugar to a control level and significantly (p < .05) inhibited diabetic up-regulation of endothelial and leukocyte intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion protein 1 (VCAM-1), endothelial cell adhesion molecules, P-selectin and E-selectin, tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), and malondialdehyde (MDA). Furthermore, insulin augmented the blood level of the anti-oxidant enzyme superoxide dismutase (SOD). We conclude that in a rat model of T2DM, insulin treatment substantially reduces aortic injury secondary to T2DM for a period of 8 weeks, possibly due to the inhibition of hyperglycemia, vascular activation, inflammation, and oxidative stress.
Intravenous sinus meningioma with intraluminal extension to the internal jugular vein: case report and review of the literature

Abstract Background Meningiomas often invade venous sinuses, but intravenous sinus meningiomas remain within the intracranial cavity. This case report describes an extremely rare case of tentorial meningioma with venous sinus invasion, extending intraluminally into the lower part of the internal jugular vein in a 59-year-old man. Case presentation The patient’s initial surgery involved the supratentorial component of a right tentorial meningioma, which invaded the right transverse and sigmoid sinuses. The supratentorial component of the tumour did not enlarge during the 2-month waiting period for the first surgery. The patient received postoperative radiation therapy for the residual tumour in the intravenous sinus. Despite radiation, the residual tumour developed caudally and ultimately extended into the right internal jugular vein. The average regrowth speed of the extracranial mass was 3.6 mm/month. The patient underwent surgery for the recurrent tumour located in the transverse sinus, sigmoid sinus, jugular bulb, and internal jugular vein, 46 months after the initial surgery. The pathological features of both surgeries were the same; WHO grade I meningothelial meningioma. Conclusions To the best of our knowledge, there have been few case reports of benign meningioma with intraluminal extension into the internal jugular vein, and there have been no reports of long-term observation of such cases. Detailed observation of the present case suggests that the difference in growth speed between the intracranial and venous cavity depends on the surrounding environment.
