Authors: AlAttas Mustafa Hussein , Edrees Hadeel Yaseen , Mohsin Syed Fareed , Javed Muhammad Qasim 
Published: March 2023

Invasive cervical resorption (ICR) is a phenomenon of unknown etiology that results in the loss of hard dental tissue. To have a successful outcome for a tooth affected by ICR, correct diagnosis and management are needed. With the introduction of new biocompatible materials and the advancement of CBCT imaging, these pathologies can be identified and treated with precision, resulting in promising outcomes. This case report aims to present the management of maxillary central incisors diagnosed with external ICR, treated with bioceramic root repair material, and followed-up to six years.

Authors: Batool Wajeeha , Naveed Shabnam , Khan Sulhera , Ahmed Syed Masroor 
Published: March 2023

Symmetric peripheral gangrene (SPG) is a rare clinical entity defined as ischemia of peripheral parts of the body without underlying vaso-occlusive disease. Its pathogenesis is unknown, but it is seen from previous reports that SPG is a sequel of underlying Disseminated Intravascular Coagulation (DIC). We report a case of a middle-aged woman who developed high-grade fever followed by painful black discoloration of the digits of four limbs, few days after spontaneous vaginal delivery at home. The patient developed septic shock. However, peripheral pulses were palpable and radiologic and laboratory investigations did not show any evidence of vessel occlusion. The patient had neutrophilic leukocytosis and a deranged clotting profile. Blood culture revealed growth of Staphylococcus Aureus and Pseudomonas Aeruginosa. The patient was diagnosed with SPG due to postpartum sepsis and DIC. She was managed with fluids, antibiotics, aspirin, and heparin but unfortunately, the patient underwent amputation of limbs due to irreversible ischemia. Therefore, prompt diagnosis and management of SPG are crucial to prevent mortality and morbidity.

Published: March 2023

The aim of our study is to present a case report of a patient who, due to advanced symmetrical peripheral diabetic polyneuropathy, was unaware of the fracture of the fifth finger of the left hand and even tried to restore it to its previous position. The 53-year-old patient with type 1 diabetes at the age of 9, who, due to non-compliance with medical recommendations and poor metabolic control (over the last 15 years, HbA1c has never fallen below 8.1%, reaching 11.1% in May 2017), developed complications such as: ischemic heart disease, diabetic retinopathy, nephropathy and peripheral neuropathy. In February 2019, in the morning, when unscrewing the fuel filler cap in the car, the patient suffered a finger fracture. He remained unaware of this fact all day due to the lack of any pain symptoms. It was only in the evening that he noticed the wrong placement of the fifth finger on his left hand. On the next day, there was a slight soreness with pressure, and the swelling deepened, which prompted him to visit the emergency room. An X-ray examination was performed there, which showed a fracture of the shaft of the proximal phalanx of the fifth finger of the left hand with angular setting of the fragments. The finger was immobilized in a plaster cast and the patient was referred for further check-up in a specialist outpatient clinic. Fortunately, the attempt to set the finger on his own did not cause any significant complications, and after removing the plaster cast, the patient regained the use of the broken finger. A recent electromyographic study confirmed the existence of a very advanced peripheral neuropathy. In summary, improperly treated, poorly controlled type 1 diabetes has serious consequences. It is very important that people suffering from it conduct regular self-monitoring of blood glucose levels and lead a healthy lifestyle.

Fiscal Limits and the Pricing of Eurobonds
Authors: Pallara Kevin , Renne Jean-Paul 
Published: March 2023

This paper proposes a methodology to price bonds jointly issued by a group of countries—Eurobonds in the euro-area context. We consider two types of bonds; the first is backed by several and joint guarantees (SJGs), and the second features several but not joint guarantees (SNJGs). The pricing of SJG and SNJG bonds reflects different assumptions regarding the pooling of debtors’ fiscal resources. We estimate fiscal limits for the six largest euro-area economies over 2008–2021 and deduce counterfactual Eurobond prices. For the five-year maturity, SNJG bond yield spreads would have been about three times larger than SJG ones over the estimation sample. Hence, issuing SJG bonds could result in gains at the aggregate level. Notwithstanding, our model also predicts that gains may temporarily vanish in periods of acute fiscal stress. We finally envision postissuance redistribution schemes, whereby gains stemming from the issuance of SJG bonds could be shared among participating countries; we argue that these schemes may alleviate the reduction in market discipline resulting from common bonds issuance.

Published: March 2023

A dual-band bandpass plasmonic filter based on quarter-wavelength effective localized surface plasmon resonators (ELSPRs) is proposed in this work. Compared with conventional microstrip resonators, ELSPRs have a larger unloaded quality factor and compact size, which can be flexibly designed. Since the harmonics of quarter-wavelength ELSPRs are located only at odd times of their dominant mode frequency, we can not only miniaturize the filter but achieve excellent out-of-band rejection performance. For demonstration, we design and fabricate a dual-band bandpass plasmonic filter, whose size is only 0.0396λ2 0 the center frequency is 3.1 GHz and 3.6 GHz, and the relative bandwidth is 10.7% and 7.7% respectively. Measurement results show excellent agreement with the simulations. Our results provide a route for realizing ultra-compact and high-performance functional devices for the fifth generation (5G) applications

Authors: Bai Lei , Zhuang Yiqi , Zeng Zhibin 
Published: March 2023

A highly compact sext-band bandpass filter (BPF) is investigated in this paper, which adopts quad-section stepped impedance resonators (SIRs) along with a series of multiple open stubs. This quad-section SIRs are constructed by tri-section SIR loaded L-shaped resonator. To achieve compact size, the filter utilizes tri-section SIR and is embedded in the double L-shaped resonators. Aseries of multiple open stubs are introduced to improve fractional bandwidth and the return loss. A sext-band BPF centering at 1.12, 2,12, 2,78, 5,59, 6.59 and 8.97 GHz has been designed and fabricated. This highly compact sext-band with wide bandwidth and simple structure is constructed on Rogers 4350 with a dielectric constant of 3.66 and a height of 0.508mm. The overall size of the fabricated filter is 0.15λ g × 0.16λ g . Good agreements are observed between the simulated and measured results.

Published: March 2023

BACKGROUND Retinoblastoma (RB) is an inherited disorder caused by the RB1 gene mutation in retinal cells or germline mutation. Identifying the specific mutation is crucial for prognosis, inheritance risk assessment, and treatment planning. This study aimed to identify the germline mutation in the RB1 gene in patients with RB and their parents from the eastern part of Indonesia.
METHODS This observational analytic study recruited patients with RB and their parents between 2016 and 2018 at Dr. Wahidin Sudirohusodo Hospital, Makassar, Indonesia. The normal control subjects were children from the outpatient clinic at the Department of Ophthalmology, Universitas Hasanuddin Hospital. Ophthalmic examinations and peripheral blood tests were performed in RB patients, their parents, and control subjects. Genomic DNA was isolated from blood leukocytes and amplified using conventional PCR. Hotspot exons 8, 10, 14, 17, and 22 were screened for mutations using the Sanger method.
RESULTS There were 21 patients with RB (16 unilateral and 5 bilateral) and 14 normal subjects. Of the 184 variations detected in RB patients, 164 were also found in normal subjects. 19 intronic mutations in introns 10, 16, 17, and 21, and 1 novel missense mutation in exon 17 were identified. Parental testing revealed 8 substitutions in exon 17 and 5 intronic mutations in introns 16 and 17 of the parents. None of the variations in exons were passed to their children.
CONCLUSIONS This study found a novel missense mutation in exon 17 of the RB1 gene.
Highly efficient method for cutting position selection of an x-ray mono-capillary lens based on an improved SCA-CSA algorithm

Published: March 2023

In order to efficiently select the optimal cutting position of x-ray mono-capillary lenses, an improved sine cosine algorithm-crow search algorithm (SCA-CSA) algorithm is proposed, which combines the sine cosine algorithm with the crow search algorithm, with further enhancements. The fabricated capillary profile is measured using an optical profiler; then the surface figure error for interest regions of the mono-capillary can be evaluated using the improved SCA-CSA algorithm. The experimental results indicate that the surface figure error in the final capillary cut region is about 0.138 µm, and the runtime is 2.284 s. When compared with the traditional metaheuristic algorithm, the particle swarm optimization algorithm, the improved SCA-CSA algorithm, enhances the surface figure error metric by two orders of magnitude. Furthermore, the standard deviation index of the surface figure error metric for 30 runs also improves by more than 10 orders of magnitude, demonstrating the superior performance and robustness of the algorithm. The proposed method provides significant support for the development of precise cuttings of mono-capillaries.
Mental health and gender-based violence: An exploration of depression, PTSD, and anxiety among adolescents in Kenyan informal settlements participating in an empowerment intervention
Authors: Friedberg Rina , Baiocchi Michael , Rosenman Evan , Amuyunzu-Nyamongo Mary , Nyairo Gavin , Sarnquist Clea 
Published: March 2023

Objective
This study examines the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) among adolescents attending schools in several informal settlements of Nairobi, Kenya. Primary aims were estimating prevalence of these mental health conditions, understanding their relationship to gender-based violence (GBV), and assessing changes in response to an empowerment intervention.

Methods
Mental health measures were added to the final data collection point of a two-year randomized controlled trial (RCT) evaluating an empowerment self-defense intervention. Statistical models evaluated how past sexual violence, access to money to pay for a needed hospital visit, alcohol use, and self-efficacy affect both mental health outcomes as well as how the intervention affected female students’ mental health.

Findings
Population prevalence of mental health conditions for combined male and female adolescents was estimated as: PTSD 12.2% (95% confidence interval 10.5–15.4), depression 9.2% (95% confidence interval 6.6–10.1) and anxiety 17.6% (95% confidence interval 11.2% - 18.7%). Female students who reported rape before and during the study-period reported significantly higher incidence of all mental health outcomes than the study population. No significant differences in outcomes were found between female students in the intervention and standard-of-care (SOC) groups. Prior rape and low ability to pay for a needed hospital visit were associated with higher prevalence of mental health conditions. The female students whose log-PTSD scores were most lowered by the intervention (effects between -0.23 and -0.07) were characterized by high ability to pay for a hospital visit, low agreement with gender normative statements, larger homes, and lower academic self-efficacy.

Conclusion
These data illustrate a need for research and interventions related to (1) mental health conditions among the young urban poor in low-income settings, and (2) sexual violence as a driver of poor mental health, leading to a myriad of negative long-term outcomes.

Published: March 2023

Background
There is limited evidence regarding predictors of functional trajectories after hip fracture. We aimed to identify groups with different trajectories of functional recovery the first year after hip fracture, and to determine predictors for belonging to such groups.

Methods
This longitudinal study combined data from two large randomized controlled trials including patients with hip fracture. Participants were assessed at baseline, four and 12 months. We used the Nottingham Extended Activities of Daily Living (NEADL) as a measure of instrumental ADL (iADL) and Barthel Index for personal ADL (pADL). A growth mixture model was estimated to identify groups of patients following distinct trajectories of functioning. Baseline characteristics potentially predicting group-belonging were assessed by multiple nominal regression.

Results
Among 726 participants (mean age 83.0; 74.7% women), we identified four groups of patients following distinct ADL trajectories. None of the groups regained their pre-fracture ADL. For one of the groups identified in both ADL outcomes, a steep decline in function was shown the first four months after surgery, and none of the groups showed functional recovery between four and 12 months after surgery.

Conclusions
No groups regained their pre-fracture ADL. Some of the patients with relatively high pre-fracture function, had a steep ADL decline. For this group there is a potential for recovery, but more knowledge and research is needed in this group. These findings could be useful in uncovering groups of patients with different functioning after a hip fracture, and aid in discharge planning.
Habitat associations of red-listed epiphytic lichens in Finland
Authors: Nirhamo Aleksi , Pykälä Juha , Jääskeläinen Kimmo , Kouki Jari 
Published: March 2023

The Finnish red list shows that the epiphytic lichen flora of Finnish forests is highly threatened and declining steeply. Red lists provide limited information on the habitat associations of threatened species, which could be relevant in informing management and conservation measures. We used documented empirical data and expert assessments to determine for each red-listed (IUCN categories Near Threatened, NT; Vulnerable, VU; Endangered, EN; Critically Endangered, CR; Regionally Extinct, RE) epiphytic lichen species of Finland the following key habitat associations: host tree species, substrate type, habitat type, geographical distribution, preferred microclimate, and minimum required forest and tree age. The most important host tree species were Picea abies (L.) H. Karst. and Populus tremula L. Other tree species of high importance included Sorbus aucuparia L. and Salix caprea L. One fourth of red-listed epiphytic lichens were primarily lignicolous. Most species required old-growth forests (required by 41% of species) or old trees (52%), but many species required only mature forests (36%) or trees (35%). The microclimatic preferences of most red-listed epiphytic lichens consisted of high or intermediate light availability and humidity. Most species whose status had deteriorated were dependent on deciduous trees. The continuous availability of old deciduous trees (especially Populus, Salix and Sorbus) requires special attention in both managed and protected forests. Red-listed epiphytic lichens would be aided by increased forest protection or transitioning to less intensive management regimes.

Abstract

Objectives
Detection of antinuclear antibodies (ANA) by indirect immunofluorescence assay using HEp-2 cells (HEp-2 IFA) is used to screen for various autoimmune diseases. HEp-2 IFA suffers from variability, which hampers harmonization.

Methods
A questionnaire was developed to collect information on HEp-2 IFA methodology, computer-assisted diagnosis (CAD) systems, training, inter-observer variability, quality assessment, reagent lot change control, and method verification. The questionnaire was distributed to laboratories by Sciensano (Belgium), national EASI groups (Italy, Croatia, Portugal, Estonia, Greece) and ICAP (worldwide). Answers were obtained by 414 laboratories. The results were analysed in the framework of the recent EFLM/EASI/ICAP ANA recommendations (companion paper).

Results
Laboratories used either HEp-2, HEp-2000, or HEp-20-10 cells and most laboratories (80%) applied the same screening dilution for children and adults. The conjugate used varied between laboratories [IgG-specific (in 57% of laboratories) vs. polyvalent]. Sixty-nine percent of CAD users reviewed the automatic nuclear pattern and 53% of CAD users did not fully exploit the fluorescence intensity for quality assurance. Internal quality control was performed by 96% of the laboratories, in 52% of the laboratories only with strongly positive samples. Interobserver variation was controlled by 79% of the laboratories. Limited lot-to-lot evaluation was performed by 68% of the laboratories. Method verification was done by 80% of the respondents.

Conclusions
Even though many laboratories embrace high-quality HEp-2 IFA, substantial differences in how HEp-2 IFA is performed and controlled remain. Acting according to the EFLM/EASI/ICAP ANA recommendations can improve the global performance and quality of HEp-2 IFA and nurture harmonization.
Building machine learning models to identify wood species based on near-infrared spectroscopy
Authors: Luo Li , Xu Zhao-Jun , Na Bin 
Published: March 2023

Abstract
Efficient and nondestructive technology for identifying wood species facilitates the transition from digital forestry to smart forestry. While near-infrared spectroscopy applied to wood identification is well documented, the detailed mechanisms for chemometrics remain unclear. In this study, twelve wood species were identified by using near-infrared spectroscopy combined with six machine learning algorithms (support vector machine, logistic regression, naïve Bayes, k-nearest neighbors, random forest, and artificial neural network). Above all, isolated forest and local outlier factor were used to detect and exclude outliers. Then feature engineering strategies were developed from three perspectives to process feature matrices: feature selection, feature extraction, and feature selection combined with feature extraction. Next, the learning curve, grid search method, and K-fold cross-validation were used to optimize the model parameters. Finally, the accuracy, operation time, and confusion matrix were used to evaluate the model performance. When the local outlier factor was used to remove outliers and principal component analysis was used to extract features, the support-vector-machine-based wood-species identification model produced the most accurate results, with 98.24% accuracy. These results offer new avenues for constructing automatic wood-identification systems.
