Abstract
In this study, an organic metal framework adsorbent was used to remove paratoluic acid from aqueous solutions. The effect of various parameters such as pH, initial concentration of paravoluic acid, contact time, and amount of adsorbent was investigated by experimental design method. Central composite design (CCD) was used to optimize paratoluic acid uptake. Initially, MIL-53 (Al) was synthesized, and characterized by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), spectroscopy, and thermogravimetry (TGA). The results of central composite design showed that pH is the most essential factor in the removal of paratoluic acid with MIL-53 (Al). The maximum removal efficiency of paratoluic acid by MIL-53 (Al) adsorbent is 93.67%, the optimal amount of adsorbent is 0.396 g, the optimal time is 35.67 min, the initial concentration is 11.12 mg L−1. The pH is 6.6 with the desired amount 1 is. Isothermal, and kinetic models have also examined. The maximum adsorption capacity was 132.05 (mg g−1), and the adsorption data of MIL-53 (Al) were well consistent with the quasi-second order, and Langmuir isotherm models.

Published: September 2022

Abstract
The aim of study is to simulate the impact of nonlinear cross gain modulation effects on optical transceiver communication systems with wide band traveling wave semiconductor optical amplifiers (WBTWSOAs). The max Q and electrical power against active amplifier length variations are simulated without/with nonlinear cross phase modulation (XPM) effect. We have been simulated the optimum Q Factor and BER at various data rate up to 160 Gbps with nonlinear cross phase modulation effect at the optimum active amplifier length of 300 μm. Also the optimum sig. power versus time and spectral wavelength is clarified with nonlinear CPM effect at the optimum active amplifier length. The total electrical power (TEP) and total optical power (TOP) are reported with nonlinear CPM effect at the optimum active amplifier length.

Abstract

Objectives
We conducted a systematic review and meta-analysis to quantitatively summarize the present data on the association of prenatally identified lateral placenta in singleton pregnancies with small for gestational age (SGA) neonates, preeclampsia and other perinatal outcomes.

Methods
From inception to November 2021, we searched PubMed/Medline, Scopus and The Cochrane Library for papers comparing the risk of SGA and preeclampsia, as well as other perinatal outcomes in singleton pregnancies with a prenatally identified lateral placenta to those with non-lateral placentas. The revised Newcastle-Ottawa Scale was used to evaluate the quality of eligible papers. The I2 test was employed to evaluate the heterogeneity of outcomes among the studies. To investigate the possibility of publication bias, funnel plots were constructed. Prospero RN: CRD42021251590.

Results
The search yielded 5,420 articles, of which 16 were chosen, comprising of 15 cohort studies and one case control study with a total of 4,947 cases of lateral and 96,035 of non-lateral placenta (controls) reported. SGA neonates were more likely to be delivered in cases with a lateral placenta (OR: 1.74; 95% CI: 1.54–1.96; p<0.00001; I2=47%). Likewise, placental laterality was linked to a higher risk of fetal growth restriction (OR: 2.18; 95% CI: 1.54–3.06; p<0.00001; I2=0%), hypertensive disorders of pregnancy (OR: 2.39; 95% CI: 1.65–3.51; p=0.0001; I2=80%), preeclampsia (OR: 2.92; 95% CI: 1.92–4.44; p<0.0001; I2=82%) and preterm delivery (OR: 1.65; 95% CI: 1.46–1.87; p<0.00001; I2=0%).

Conclusions
The prenatal diagnosis of a lateral placenta appears to be associated with a higher incidence of preeclampsia, fetal growth restriction, preterm delivery and SGA. This may prove useful in screening for these conditions at the second trimester anomaly scan.

Abstract

Objective
The objective of this study is to report results from the open-label extension (OLE) of the OPTIMAL trial of oral octreotide capsules (OOC) in adults with acromegaly, evaluating the long-term durability of therapeutic response.

Design
The study design is an OLE of a double-blind placebo-controlled (DPC) trial.

Methods
Patients completing the 36-week DPC period on the study drug (OOC or placebo) or meeting predefined withdrawal criteria were eligible for OLE enrollment at 60 mg/day OOC dose, with the option to titrate to 40 or 80 mg/day. The OLE is ongoing; week 48 results are reported.

Results
Forty patients were enrolled in the OLE, 20 each having received OOC or placebo, with 14 and 5 patients completing the DPC period as responders, respectively. Ninety percent of patients completing the DPC period on OOC and 70% of those completing on placebo completed 48 weeks of the OLE. Maintenance of response in the OLE (i.e. insulin-like growth factor I (IGF1) ≤ 1.0 × upper limit of normal (ULN)) was achieved by 92.6% of patients who responded to OOC during the DPC period. Mean IGF1 levels were maintained between the end of the DPC period (0.91 × ULN; 95% CI: 0.784, 1.045) and week 48 of the OLE (0.90 × ULN; 95% CI: 0.750, 1.044) for those completing the DPC period on OOC. OOC safety was consistent with previous findings, with no increased adverse events (AEs) associated with the higher dose and improved gastrointestinal tolerability observed over time.

Conclusions
Patients with acromegaly maintained long-term biochemical response while receiving OOC, with no new AEs observed with prolonged OOC exposure.
Grammatical Features of the Moscow Edition of the Trebnik in the Middle of the 17th Century (on the Material of a Comparative Study of Trebnik by Nikon in 1658 and Trebnik by Peter Mohyla in 1646)
Authors: Molkov Georgiy , Sharikhina Miliausha 
Published: September 2022

The paper studies the grammar features that characterize the Moscow revision of the Book of Needs (Trebnik), composed under patriarch Nikon (1658). The research is based on a comparison of Nikon’s and Peter Mogila’s (1646) Trebniks. The study confirmed the scientific statement that Nikonian editors revised the Trebnik in accordance with the recommendations of the Moscow edition of M. Smotritsky’s Grammar. This is shown, for example, in the use of certain endings in the nominal and adjective declension and of the imperative indicator (in the verbs of the first conjugation in the 1st and 2nd persons of the plural). The emergence of hyper-correct phenomena points at to obligatory character of the corrections. One of the main directions of the Nikonian edition was the elimination of grammatical variability and homonymy. To this end, editors fixed one form for expressing grammatical meaning in those cases when the grammar allowed variations, for example, the use of the ending -ѣхъ in the local masculine and neuter plurals, the elimination of the enclitic forms of personal pronouns in the dative case in the adnominal position and their replacement by possessive pronouns, the use of reflexive verbs to express passive in place of combinations of passive participles with the verb byti (быти).

Macular amyloidosis (MA) is the subtlest of the cutaneous varieties of amyloidosis. In general, the treatment of MA is disappointing. Hence, this study was aimed at comparing the two treatment modalities for the same. To compare the efficacy of 30% TCA chemical peel with Q switched Nd-YAG laser 1064nm in the treatment of macular amyloidosis. 50 patients of MA attending our Dermatology outpatient department were enrolled in the study. The study involved application of 30% TCA in 25 patients at an interval of 2 weeks for 10 sittings and Q switched Nd-YAG laser 1064 in 25 patients at an interval of 1 month for 5 sittings. Digital photographs were taken before treatment and then periodically. The response was graded percentage of reduction in pigmentation both by the patient and the observer. The patients were followed up for 5 months post treatment for recurrence. Both TCA peel and Q switched Nd-Yag laser 1064nm were effective in the treatment of macular amyloidosis. switched Nd-Yag laser 1064nm showed better response compared to TCA peel at the end of the treatment, both by subjective and objective methods and in terms of less number of sittings and fewer side effects. The difference was statistically significant (P &#60;0.05).No permanent side effects were seen in any of the treated patients and the improvement was sustained without any relapse at 5 months except in one patient in the peel group. Both these treatment modalities are effective and safe in the treatment of MA. Q switched Nd-Yag laser 1064nm was found to be marginally superior to TCA peel.

: Psoriaisis is a common papulosquamous condition seen by the dermatologists. It can involve the skin and nails. There are many sub types of Psoriasis with various clinical, histopathological and dermoscopic features. In this study we intend to study the epidemiological, clinical, histopathological and dermoscopic features of Chronic Plaque Psoriasis (CPP).: A total of 45 patients of CPP, above the age of 18 years who qualified the inclusion and exclusion criteria were included in the study. A proforma of epidemiological details was noted, clinical and dermoscopic examination of the lesions were done. The punch biopsy specimens of cutaneous lesions were subjected to histopathological examination and the findings noted. : Out of the 45 patients included in the study, 31 were males and 14 females with a ratio of 2.21:1. The commonest symptom at presentation was flaking of skin and the most common site of involvement was trunk. On dermoscopic examination, dotted vessels and white scales were seen in all the patients. Hyperkeratosis, Parakeratosis, Acanthosis, Munro’s microabscess, Hypogranulosis were the significant histopathological features.: Psoriasis is more common in young adults and shows a male preponderance. Presence of dotted vessels in a regular distribution on dermoscopy is classical of CPP. Hyperkeratosis, Hypogranulosis and Munro’s microabscess are notable features of histopathology of LP.

Published: September 2022

The papulosquamous skin disorders are a diverse set of conditions that constitute the most common diseases seen by dermatologists. There is a lot of overlap in the appearance and distribution of lesions, which makes diagnosis challenging. The skin, the body's largest organ, responds to pathogenic stimuli in a restricted number of ways. As a result, histological patterns in clinically distinct lesions may be similar. A thorough histological evaluation is considered the gold standard in diagnosing skin disorders, but it has limits, and without clinical information, a definitive specific diagnosis is often impossible. In many circumstances, a diagnosis might be made by comparing histopathological and clinical findings.A Prospective study was carried out in the Department of Dermatology from September 2019 to September 2021. Patients presenting with clinically papulosquamous disorder were photographed and a presumptive clinical diagnosis was made based on clinical features; which was confirmed by histopathological examination and correlation between clinical and histopathological findings was studied. The study included 202 patients in which clinico-histopathological correlation was done. In 88.11% cases a positive correlation was established whereas a negative correlation was obtained in 11.89%cases. Psoriasis constituted the highest cases 64(31.68%) followed by lichen planus 52(25.74%).Majority of the papulosquamous disorders have an overlapping clinical presentation as skin reacts in a limited pattern towards any pathologic stimuli. There is a need for clear clinical information and a description of the lesion to assist the histopathologist in arriving at a conclusive diagnosis, which is the gold standard, to overcome the associated complexity in diagnosing and commencing the right treatment. For a more accurate differentiation of various papulosquamous disorders, histopathology is very crucial for appropriate medical management. This is clearly seen and supported by the present study.

Published: September 2022

Since its emergence in 2019, RT-PCR is a standard test for the detection of SARS-CoV-2 viral infection (COVID-19). Chest-CT scans are the preferred most common routine test to determine the spread and severity of the disease. The present study aims to demonstrate a comparative analysis of chest CT and RT-PCR as diagnostic tests for COVID-19 detection.In this prospective single-center study a total of 979 patients (Male= 614, female= 365) from Tumkur, Karnataka (India) who were suspected of novel coronavirus infection underwent both chest CT and RT-PCR assay.Patients with positive RT-PCR and abnormalities in chest CT images were identified. The patients with negative RT-PCR and positive chest-CT images and vice versa were screened for the accuracy of both techniques. Out of 979 patients, 674 (68.85%) patients had positive CT index scores, whereas 613 (62.61%) patients had positive RT-PCR tests. Most of the patients (47%) were from the age group 36-55 years with most of the population having hypertension (8.27%) and diabetes (6.44%). Corad score revealed 88.36% of patients (865) with high infection. In patients with negative RT-PCR reports (31.15%; 305/979), a positive CT index was observed in 7.25% of patients indicating higher sensitivity to this technique. A chest CT scan is superior in sensitivity for the detection of COVID-19 than that of RT-PCR. The CT scan can be used asa confirmatory diagnostic test for COVID-19 suspects whose RT-PCR test results are negative.

Published: September 2022

In India, several social, cultural, religious and economic factors influence menstrual hygiene and practices among women. In country like India menstruation is generally considered as unclean and there is a lack of knowledge about menstruation and its practices among women. Practices like isolation and imposing restrictions among menstruating girls in the family, have reinforced a negative attitude. A community based cross sectional study was conducted among the reproductive age women residing under urban and rural health centres of Belagavi city, Karnataka. A total of 280 women have participated in our study. Majority of the women are in the age group of 20-24 years (32.6%). More than half of the women were house wife (69.6%). While more than half of the families of the women belong to lower socio-economic level i.e class III, IV &V (76.1%). 90.7% opined that menstruation is a physiological process, 83.6% were unaware about the cause of menstruation, while information regarding prior to menarche, 68.5% said they didn’t had any information, while those who got information, most of them are from their mother (42.9%). On usage of sanitary pads, 63.2% were aware about it. 30.3% said they used same cloth every month. Disposal of absorbent material, 53.5% disposed in garbage, while 16.7% reused them. The study revealed that menstrual hygiene among large population of women was far from satisfactory. Lack of sufficient information about menstrual hygiene can be largely attributed to various cultural and religious beliefs and taboos.
