Social Media in the Time of a Pandemic
Authors: Nayyar Anjali , Bose Nilanjana , Shrivastava Roli , Basu Ria , Andries Sarah 
Published: August 2023

AbstractSocial media has evolved from being a set of rudimentary tools to a complex instrument that has had both positive and negative consequences, often leading to widespread circulation of misinformation impacting societies and institutions. The COVID-19 pandemic, significantly, is the first health crisis, witnessed globally in the age of social media and amidst unprecedented connectivity. Throughout the pandemic, the world has witnessed a widespread use of social media. The medium has not only enabled isolated people to remain connected with their friends and families but also to communicate with medical experts. At the same time, myths about COVID-19, its treatment, and effects have circulated on the same platforms leading governments to issue guidelines in several countries including India. While social media has enabled a regular flow of information, it has also led to unverified content circulating on platforms such as Twitter and Facebook, fueling panic in people about the virus and the vaccines. This chapter explores the role social media platforms (Facebook, Twitter, Instagram, and others) have played in enhancing and delivering evidence, connecting communities and also in circulating myths and unverified content during the COVID-19 pandemic. Through quantitative analysis, it encapsulates trends being witnessed in different geographies. It will conclude with learnings that we have gathered on leveraging this medium which can be used going forward in instances of future health crises.
The Social, Education, Health, and Economic Effects of the COVID-19 Pandemic on Kenya’s Adolescents
Authors: Mwabe Julie , Austrian Karen 
Published: August 2023

AbstractThe first case of COVID-19 was detected in Kenya in March 2020. Initial government responses included several containment measures such as school closures, movement limitations, and bans on public gatherings. These measures had many follow-on effects, in particular for the country’s vulnerable adolescents. Between June 2020 and February 2021 two round of quantitative data was collected in four counties in Kenya (Kilifi, Kisumu, Nairobi, and Wajir) via phone surveys (n = 3,921). In addition, qualitative in-depth interviews were conducted in person in November 2020 with adolescents, parents, and other key stakeholders (n = 234). Results showed that the pandemic’s effects on adolescents were wide-reaching and often differed by gender. While 85% of students reported doing some form of remote learning during school closures, 98% of them reported considerable challenges with less than one-third using technology (i.e., computers, phones, television, and radio) to support their learning. Over half of the adolescents reported depressive symptoms and over three-quarters reported skipping meals in the past week due to COVID-19. Twelve percent of girls and 9% of boys reported skipping healthcare services in the past one month, with the most common reason being lack of money to access the needed service. Once school had fully re-opened, 16% of girls and 8% of boys who were enrolled at the start of the pandemic had not re-enrolled. Given the wide, multi-sectoral nature of the impacts of the pandemic, a coordinated response involving education, health, and gender actors, as well as government and non-government partners, will be needed to mitigate the long-term negative impacts for Kenya’s adolescents, in particular girls and other marginalized groups.
Addressing the Urgency and Magnitude of the COVID-19 Pandemic in India by Improving Healthcare Workforce Resilience

Published: August 2023

AbstractThe sudden surge in COVID-19 cases during the second wave highlighted India’s lack of preparedness for critical care requirements in terms of infrastructure and human resources. It is the need of the hour to make efforts to build resilient and responsive health systems that are well prepared to handle the current COVID-19 pandemic and similar future threats. The challenges in the healthcare system during the second wave of COVID-19 included overstressed human resources in tertiary facilities, lack of trained healthcare workers, inadequate infrastructure at secondary-level facilities, and a shortage of beds, ventilators, medicines, and other requirements for tertiary-level care. Other challenges were lack of resources/capacity for setting up intensive care units (ICUs), unutilized ICU equipment at secondary-level facilities, and lack of operational planning, coordination, and support. Through the United States Agency for International Development (USAID) supported Reaching Impact, Saturation, and Epidemic Control (RISE) Program, Jhpiego is providing technical assistance in 20 states across India to respond to the urgency and magnitude of the second wave of COVID-19. It is identifying areas and modalities of implementation and aligning these to the country’s response to the surge. The project’s focus is on health system preparedness for present and future waves of COVID-19 including activities for strengthening critical care services, medical oxygen management, strengthening molecular testing laboratory, strengthening the health system to respond to future waves, and enabling effective planning and management of critical logistics. This is being done in coordination with the Government of India (GoI) and state governments and by involving both public and private sector/faith-based institutions and non-government organizations (NGOs).
Bridge Over Troubled Waters: Women-led Response to Maternal and Child Health Services in India Amidst the COVID-19 Pandemic
Authors: Kant Aastha , Hazra Avishek 
Published: August 2023

AbstractGlobally, the COVID-19 pandemic has disrupted the delivery of essential health services in general and reproductive, maternal, newborn, child health, and nutrition (RMNCHN) services in particular. The degree of disruption, however, varies disproportionately. It is more in low- and middle-income countries than in high-income countries. Focusing on India, the authors draw on various demand and supply side factors that hampered the provision of RMNCHN services and thus adversely affected many families across the country. Coupled with the gendered aspects of the social determinants of health, the pandemic intensified social vulnerabilities by impacting pregnant and lactating women and children the most. Modelling studies suggest that the progress India made over a decade on various maternal and child health and nutrition indicators may go in vain unless focused efforts are made to address the slide. Complementing government efforts to mitigate the health risks of the pandemic by strengthening health services, women-led initiatives played an important role in portraying how women’s collectives and women in leadership can be like a bridge over troubled waters in the times of a pandemic.
The one-loop unimodular graviton propagator in any dimension
Authors: Anero Jesus , Martin Carmelo P. , Velasco-Aja Eduardo 
Published: August 2023

Abstract
For unimodular gravity, we work out, by using dimensional regularization, the complete one-loop correction to the graviton propagator in any space-time dimension. The computation is carried out within the framework where unimodular gravity has Weyl invariance in addition to the transverse diffeomorphism gauge symmetry. Thus, no Lagrange multiplier is introduced to enforce the unimodularity condition. The quantization of the theory is carried out by using the BRST framework and there considering a large continuous family of gauge-fixing terms. The BRST formalism is developed in such a way that the set of ghost, anti-ghost and auxiliary fields and their BRST changes do not depend on the space-time dimension, as befits dimensional regularization. As an application of our general result, and at D = 4, we obtain the renormalized one-loop graviton propagator in the dimensional regularization minimal subtraction scheme. We do so by considering two simplifying gauge-fixing choices.
Strange-quark mass effects in the Bs meson’s light-cone distribution amplitude
Authors: Feldmann Thorsten , Lüghausen Philip , Seitz Nicolas 
Published: August 2023

Abstract
We investigate the differences between the light-cone distribution amplitudes (LCDAs) of Bs mesons and Bq mesons (with q = u, d) induced by a non-vanishing strange-quark mass ms ≠ 0 (compared to mq ≃ 0). To this end, we consider the so-called “radiative tail” which is related to the short-distance expansion of the relevant light-ray operators in heavy-quark effective theory. We extend the calculation of the according matching coefficients, including operators linear in ms for both the leading and sub-leading 2-particle LCDAs. Based on a generic parameterization for the leading LCDA, we discuss the effect on its shape on a quantitative level, and compare our findings with recent results on the inverse moments of the Bq and Bs LCDAs from QCD sum rules.

AbstractControlled mRNA storage and stability is essential for oocyte meiosis and early embryonic development. However, how to regulate mRNA storage and stability in mammalian oogenesis remains elusive. Here we showed that LSM14B, a component of membraneless compartments including P-body-like granules and mitochondria-associated ribonucleoprotein domain (MARDO) in germ cell, is indispensable for female fertility. To reveal loss of LSM14B disrupted primordial follicle assembly and caused mRNA reduction in non-growing oocytes, which was concomitant with the impaired assembly of P-body-like granules. 10× Genomics single-cell RNA-sequencing and immunostaining were performed. Meanwhile, we conducted RNA-seq analysis of GV-stage oocytes and found that Lsm14b deficiency not only impaired the maternal mRNA accumulation but also disrupted the translation in fully grown oocytes, which was closely associated with dissolution of MARDO components. Moreover, Lsm14b-deficient oocytes reassembled a pronucleus containing decondensed chromatin after extrusion of the first polar body, through compromising the activation of maturation promoting factor, while the defects were restored via WEE1/2 inhibitor. Together, our findings reveal that Lsm14b plays a pivotal role in mammalian oogenesis by specifically controlling of oocyte mRNA storage and stability.

Published: August 2023

Abstract
Purpose
To determine predictive factors associated with a good response (GR) to and efficacy of low-dose radiotherapy (LDRT) in patients with greater trochanteric pain syndrome (GTPS).

Methods
Patients with GTPS were irradiated on a linear accelerator with 0.5–1.0 Gy per fraction to a total dose of 3.0–4.0 Gy per series. The endpoint was subjective good response (GR) to treatment 2 months after completion of the last LDRT series, defined as complete pain relief or marked improvement assessed using the von Pannewitz score. A positive response to steroid injection (SI) was defined as pain relief of at least 7 days. Patient and treatment-related characteristics were evaluated with respect to LDRT outcomes.

Results
Outcomes were assessed for 71 peritrochanteric spaces (PTSs; 65 patients, 48 females, with mean age of 63 [44–91] years). Prior SI had been given to 55 (77%) PTSs and 40 PTSs received two series of LDRT. Two months after completion of LDRT, GR was reported in 42 PTSs (59%). Two series of LDRT provided a significantly higher rate of GR than one series (72.5 vs. 42% PTSs, p = 0.015). Temporary pain relief after prior SI predicted GR to LDRT compared with PTSs which had not responded to SI (73 vs. 28% PTSs, p = 0.001). A regional structural abnormality, present in 34 PTSs (48%), was associated with a reduction of GR to LDRT (44 vs. 73% PTSs, p = 0.017).

Conclusion
LDRT is an effective treatment for GTPS. Administration of two LDRT series, prior response to SI, and absence of structural abnormalities may predict significantly better treatment outcomes.

Published: August 2023

Abstract
Purpose
Every year, approximately 10 million people worldwide suffer a traumatic brain injury that leads to hospitalization or mortality. Chronic and acute alcohol intoxication increase the risk of developing traumatic brain injury. Alcohol use disorder (AUD) as a predictor of outcome in neurosurgical patients and the definition of risk factors have been sparsely addressed so far. This study aims to improve the understanding of the effects of alcohol use disorder in the context of neurosurgical therapy.

Methods
This study included patients admitted to Münster University Hospital with a traumatic brain injury and alcohol use disorder from January 1, 2010, to December 31, 2018. Univariate and multivariate analyses were performed to identify risk factors for a poorer outcome, assessed by the Glasgow Outcome Score.

Results
Of the 197 patients included, 156 (79%) were male, and 41 (21%) were female, with a median age of 49 years (IQR 38–58 years). In multivariate analyses, age (p < 0.001), the occurrence of a new neurologic deficit (p < 0.001), the development of hydrocephalus (p = 0.005), and CT-graphic midline shift due to intracerebral hemorrhage (p = 0.008) emerged as significant predictors of a worse outcome (GOS 1–3). In addition, the level of blood alcohol concentration correlated significantly with the occurrence of seizures (p = 0.009).

Conclusions
Early identification of risk factors in patients with alcohol use disorder and traumatic brain injury is crucial to improve the outcome. In this regard, the occurrence of hydrocephalus or seizures during the inpatient stay should be considered as cause of neurological deterioration in this patient group.
Measurement of surface-checking in sliced lamellae-based engineered wood flooring using digital image correlation
Authors: Grubîi Victor , Johansson Jimmy , Dagbro Ola 
Published: August 2023

AbstractThe lack of quantitative methods for surface-checking measurements may hinder improving the product characteristics of engineered wood flooring products built with sliced top-layer lamellae. This study evaluated the digital image correlation method for its applicability to surface checking measurements in engineered wood flooring elements with the top-layer comprising the plain sliced lamellae of oak (Quercus spp.) species with nominal thicknesses of 1.5–4.5 mm. The method involves observing full-field surface displacements of the sliced lamellae-based wood flooring specimens subjected to an accelerated sorption/desorption cycle. Detection of surface checks relates to discontinuities in surface displacements which can be interpreted from the output strain data as strain peak regions. Additionally, a surface-checking index was defined to describe the extension of surface-checking. Exposure tests were performed on a combination of coating presence and a different number of testing cycles. The main findings provide insight into the method procedure parameters, such as exposure duration, climate conditions, analysis parameters and recommendations regarding the digital image correlation setup settings and specimen manufacturing.

AbstractBinary feedback, providing information solely about task success or failure, can be sufficient to drive motor learning. While binary feedback can induce explicit adjustments in movement strategy, it remains unclear if this type of feedback also induces implicit learning. We examined this question in a center-out reaching task by gradually moving an invisible reward zone away from a visual target to a final rotation of 7.5° or 25° in a between-group design. Participants received binary feedback, indicating if the movement intersected the reward zone. By the end of the training, both groups modified their reach angle by about 95% of the rotation. We quantified implicit learning by measuring performance in a subsequent no-feedback aftereffect phase, in which participants were told to forgo any adopted movement strategies and reach directly to the visual target. The results showed a small, but robust (2–3°) aftereffect in both groups, highlighting that binary feedback elicits implicit learning. Notably, for both groups, reaches to two flanking generalization targets were biased in the same direction as the aftereffect. This pattern is at odds with the hypothesis that implicit learning is a form of use-dependent learning. Rather, the results suggest that binary feedback can be sufficient to recalibrate a sensorimotor map.

AbstractCytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is a treatment option for peritoneal carcinomatosis (PC) from colorectal cancer (CRC), which is otherwise a terminal stage of disease. Nevertheless, survival outcomes are only marginally superior to other treatments. This fact highlights the need for better strategies to control intra-abdominal disease recurrence after CRS-HIPEC, including the complementary use of immunotherapies. The aim of this study was therefore to investigate the immune phenotype of T cells in patients with PC. Fifty three patients with CRC (34 patients with PC and 19 patients without PC) were enrolled in a prospective study (clinicaltrials.gov: NCT04108936). Peripheral blood and omental fat were collected to isolate peripheral blood mononuclear cells (PBMCs) and adipose tissue mononuclear cells (ATMCs). These cells were analysed by flow cytometry using a panel focused upon T cell memory differentiation and exhaustion markers. We found a more naïve profile for CD8+T cells in peripheral blood and intra-abdominal fat of PC patients compared to comparator group (CG) patients. Furthermore, there was an over-representation of CD4+T cells expressing inhibitory receptors in adipose tissue of PC patients, but not in blood. Our description of intraperitoneal T cell subsets gives us a better understanding of how peritoneal carcinomatosis shapes local immune responses.
Self-organized submicron structures in photoresist films by UV-laser irradiation at water-confined conditions
Authors: Ehrhardt Martin , Lai Shengying , Lorenz Pierre , Zajadacz Joachim , Han Bing , Zimmer Klaus 
Published: August 2023

AbstractA new kind of self-organized pattern formation process has been found during laser irradiation of polymer films in water confinement just below the laser ablation threshold, resulting in a randomly oriented pattern with a period of about 475 nm. The morphology, orientation, period, and amplitude of these patterns are inconsistent with both laser-induced periodic surface structures that typically consist of linear grooves with periods smaller the laser wavelength and wrinkling patterns that feature a much larger period and appear at layered systems. Excimer laser (λ = 248 nm, tp = 25 ns) exposure of 650 nm thick photoresist films on silicon wafers cause the growth of irregular submicron patterns. The pattern morphology that is examined with imaging techniques is correlated to processing parameters. The amplitude of these laser-induced self-organized (LISE) submicron structures are strengthened with pulse number and laser fluence. The experimental results are discussed together with simulations of laser heating the photoresist film in water confinement. The proposed pattern formation mechanism of such laser-induced self-organized submicron structures at temporal excitation of a confined polymer surface comprises the formation of an oriented roughness based on LIPSS that are developed to wrinkled structures due to the transient formation of a soft subsurface area that provides conditions for wrinkling of the water cooled, stiff polymer surface by laser-induced stress fields. Size, amplitude, and morphology of the LISE pattern provide good properties for applications in such fields as wetting, friction, optics, and bioactivity.

Published: August 2023

AbstractBetween 38.5 ka cal BP and 32.4 ka cal BP, a dacitic Volcanic Explosivity Index 5 eruption at Misti volcano emplaced the Sacarosa tephra-fall deposit. Its biotite phenocrysts, fine grain size, scarce lithics, and abundant loose crystals characterize the deposit at locations sampled. The eruption’s ~ 800 °C magma rose rapidly from ~ 10 km depth, culminating in a Plinian eruption which reached a mass eruption rate of 7.7 × 106–4.1 × 107 kg/s and emplaced about 3 km3 of tephra within tens of hours. The unit comprises two layers of subequal thickness separated by a diffuse contact with the upper distinguished by being slightly coarser and less well sorted than the lower. The deposit’s coarser upper layer indicates either climactic conditions or a lesser degree of fragmentation during the latter half of the eruption. Strong winds distributed the deposit southwest of Misti, where it crops out over at least 800 km2 and drapes the present site of Arequipa with up to 100 cm of tephra. The Sacarosa deposit is the first among the Cayma stage deposits, a distinctive group of felsic, biotite-bearing units, to be carefully described and its eruption characterized. Several Cayma stage deposits were emplaced by voluminous explosive eruptions similar to the Sacarosa eruption, representing a ~ 8.9–15.5 ky interval of powerful eruptions. Such an explosive eruption today would threaten Arequipa’s over 1,100,000 residents, many of whom live within the Sacarosa deposit’s distribution.
