Особливості формування домінантного комплексу фітопланктону у водних об’єктах різного типу
Authors: Sheliuk Iulia , Konstantinenko Liudmila 
Published: February 2022

Багаторічними дослідженнями (2005–2020 рр.) встановлено особливості формування домінантного комплексу фіто-планктону різнотипних водних об’єктів Українського Полісся (річок, озер, водосховищ і водойм, утворених на місці затоплених кар’єрів із видобутку піску, гранітів та ільменітів). У різні сезони до домінуючих належало 216 видів, що складає 24,6 % від їх зага-льного числа, ідентифікованих у складі фітопланктону водойм та водотоків регіону. У флористичному відношенні у складі доміна-нтних комплексів найбагатше представлені відділи діатомових (29,7 % від загальної кількості видів-домінантів), зелених (24,1 %) і евгленових водоростей (19,4 %). Таке співвідношення властиве водоростевим угрупованням планктону всіх досліджуваних типів водних екосистем.
Найбільша подібність складу домінантних комплексів властива планктону річок і створених на них водосховищ (k=0,48), та-кож встановлено значну подібність між списками видів-домінантів озер і водойм, утворених на місці затоплених кар’єрів (k=0,41).
У більшості досліджених водних об’єктів насиченість складу домінантних комплексів суттєво не змінювалася впродовж ве-гетаційних сезонів, лише у Дідовому та Острівському озерах у літній період відзначали збільшення числа видів, які формують до-мінантний комплекс, із подальшим його збідненням восени.
У складі домінантних комплексів фітопланктону виявлено 11 видових і внутрішньовидових таксонів водоростей, нових для Українського Полісся. Поява у складі домінантних комплексів нових для регіону видів значною мірою зумовлена змінами гідроло-гічного й гідрохімічного режимів водойм і водотоків, пов’язаними з зарегулюванням, осушувальною меліорацією, змінами клімату, а також появою штучних водойм на місці затоплених кар’єрів із видобутку корисних копалин.

In the market conditions of dairy cattle breeding, the problem of increasing productivity comes to the fore of cost-effective milk production. As best practices and zootechnical studies show, the productivity of cows is already laid at the level of raising calves of the dairy period. The main feed for calves of the dairy period is currently whole milk, but due to its deficiency, various substitutes based on skimmed milk powder with various additives of vitamins and trace elements are produced. However, due to high cost, the use of whole milk replacers has not been widely used. In this regard, to increase profitability of dairy cattle breeding, as well as for accelerated development, calves are accustomed to consuming vegetable feeds. Since plant-based feeds are difficult to digest in a young body, they must be processed into easily digestible. The paper presents an innovative technology and an automated set of equipment for production of easily digestible concentrate based on local grain raw materials for replacement young animals. It has been determined that the use of an innovative automated set of equipment for production of easily digestible concentrate for feeding calves of the dairy period contributes to: faster development of rumen, higher digestibility of grain components due to proper processing, since during preparation of the concentrate, protein denaturation, inactivation of anti-nutritional substances and starch hydrolysis to maltose occur; obtaining optimal weight gain of calves (over 700 g), which will lead to creation of a basis for future high milk productivity of cows; simplification of calf feeding technology; reducing the consumption of milk or whole milk replacer for feeding calves.

Authors: Kulandaiammal Rosy 
Published: February 2022

Abstract
Our life on earth often is dashed by hardships, losses, and crises. Naturally, these adverse life events and tragedies create doubt and disbelief about the meaning of life, and our human mind engaged with helplessness, despair, and negativity. However, human's physical and psychological immune systems have programmed through the evolutionary process of survival of the fittest. It makes us capable of overcoming the threats and adversities and showing greater resilience and courage to respond to the demand. At present, the COVID -19 pandemic has paralyzed human life in all aspects irrespective of the social, economic status across the world in 216 countries, areas, or territories. Pandemic causes panic, insecure feelings about life and death, fear of transmission of infection, and so on. The field of positive psychology studies human strengths and potentials that are the ingredients of our well-being, resilience, adjustment, and adaptation to any adverse situations of life. This review article attempts to show the relevance of positive psychology and how positive psychological adaptation and its constructs help to strengthen humankind in times of adversity.
Counseling with an emphasis in Health Psychology: Cognitive-Behavioral Therapy for Autism spectrum Children
Authors: Allari Layla , Allari Rabia 
Published: February 2022

Cognitive behavioral therapy is based on the concept that one’s thoughts, feelings, physical actions, and sensations are interlinked. It also works on the basis that undesirable opinions and feelings can potentially catch an individual in a vicious cycle and that changing negative patterns can help an individual improve the way they feel about various things. Using cognitive behavioral therapy will allow the client to self-explore and identify what factors in life are causing problems or specific concerns. Cognitive behavioral therapy can help the children with Autism spectrum disorder to overcome the social and communication barriers if the levels of anxiety that they are feeling have dropped. Social skills and managing challenging behaviors such as anxiety and emotional regulation are also important and will be useful for children with Autism spectrum disorder to improve language/speech use, social communication/interactions, and symptom severity.

OBJECTIVE
Traditionally, patients who underwent elective craniotomy for epilepsy surgery are monitored postoperatively in an intensive care unit (ICU) overnight in order to sufficiently respond to potential early postoperative complications. In the present study, the authors investigated the frequency of early postoperative events that entailed ICU monitoring in patients who had undergone elective craniotomy for epilepsy surgery. In a second step, they aimed at identifying pre- and intraoperative risk factors for the development of unfavorable events to distinguish those patients with the need for postoperative ICU monitoring at the earliest possible stage.

METHODS
The authors performed a retrospective observational cohort study assessing patients with medically intractable epilepsy (n = 266) who had undergone elective craniotomy for epilepsy surgery between 2012 and 2019 at a tertiary care epilepsy center, excluding those patients who had undergone invasive diagnostic approaches and functional hemispherectomy. Postoperative complications were defined as any unfavorable postoperative surgical and/or anesthesiological event that required further ICU therapy within 48 hours following surgery. A multivariate analysis was performed to reveal preoperatively identifiable risk factors for postoperative adverse events requiring an ICU setting.

RESULTS
Thirteen (4.9%) of 266 patients developed early postoperative adverse events that required further postoperative ICU care. The most prevalent event was a return to the operating room because of relevant postoperative intracranial hematoma (5 of 266 patients). Multivariate analysis revealed intraoperative blood loss ≥ 325 ml (OR 6.2, p = 0.012) and diabetes mellitus (OR 9.2, p = 0.029) as risk factors for unfavorable postoperative events requiring ICU therapy.

CONCLUSIONS
The present study revealed routinely collectable risk factors that would allow the identification of patients with an elevated risk of postsurgical complications requiring a postoperative ICU stay following epilepsy surgery. These findings may offer guidance for a stepdown unit admission policy following epilepsy surgical interventions after an external validation of the results.
Impact of salvage surgery for recurrent sinonasal cancers with skull base and intracranial involvement
Authors: Schur Solon E. , Hanna Ehab Y. , Su Shirley Y. , Kupferman Michael E. , DeMonte Franco , Raza Shaan M. 
Published: February 2022

OBJECTIVE
Patients with recurrent sinonasal cancers (RSNCs) often present with extensive involvement of the skull base and exhibit high rates of subsequent recurrence and death after therapy. The impact of salvage surgery and margin status on progression-free survival (PFS) and overall survival (OS) has yet to be demonstrated. The goal of this study was to determine whether skull base resection with negative margins has an impact on outcomes in the recurrent setting.

METHODS
A retrospective chart review of 47 patients who underwent surgery for RSNC with skull base invasion between November 1993 and June 2020 was conducted. The following variables were extracted from the clinical records: patient demographic characteristics (age and sex), tumor pathology, dural and orbital invasion, and prior radiation exposure and induction chemotherapy. Metastatic disease status, surgical approach, margin status, and history of postoperative chemotherapy and/or postoperative radiation therapy were noted. The primary and secondary outcomes were PFS and OS, respectively.

RESULTS
The cohort included 30 males (63.8%) and 17 females (36.2%), with a mean ± SD age of 54.8 ± 14.4 years. Thirty-five (74.5%) patients showed disease progression, and 29 (61.7%) patients died during the study period. The mean ± SD patient follow-up period was 61.8 ± 64.4 months. Dural invasion was associated with increased risk of death (HR 2.62, 95% CI 1.13–6.08). High-risk histopathology (HR 3.14, 95% CI 1.10–8.95) and induction chemotherapy (HR 2.32, 95% CI 1.07–5.06) were associated with increased odds of disease progression. When compared to patients with positive margins or gross-total resection with unknown margin status, those with negative margins had decreased odds of disease progression (HR 0.30, 95% CI 0.14–0.63) and death (HR 0.38, 95% CI 0.17–0.85).

CONCLUSIONS
RSNCs show high rates of subsequent disease progression and mortality. This study demonstrated that negative margins may be associated with improved PFS and OS in carefully selected patients who have undergone salvage surgery for RSNC.

OBJECTIVE
The object of this study was to evaluate the safety, efficacy, and long-term outcomes of stereotactic radiosurgery (SRS) in the management of intracranial chordomas.

METHODS
This retrospective multicenter study involved consecutive patients managed with single-session SRS for an intracranial chordoma at 10 participating centers. Radiological and neurological outcomes were assessed after SRS, and predictive factors were evaluated via statistical methodology.

RESULTS
A total of 93 patients (56 males [60.2%], mean age 44.8 years [SD 16.6]) underwent single-session SRS for intracranial chordoma. SRS was utilized as adjuvant treatment in 77 (82.8%) cases, at recurrence in 13 (14.0%) cases, and as primary treatment in 3 (3.2%) cases. The mean tumor volume was 8 cm3 (SD 7.3), and the mean prescription volume was 9.1 cm3 (SD 8.7). The mean margin and maximum radiosurgical doses utilized were 17 Gy (SD 3.6) and 34.2 Gy (SD 6.4), respectively. On multivariate analysis, treatment failure due to tumor progression (p = 0.001) was associated with an increased risk for post-SRS neurological deterioration, and a maximum dose > 29 Gy (p = 0.006) was associated with a decreased risk. A maximum dose > 29 Gy was also associated with improved local tumor control (p = 0.02), whereas the presence of neurological deficits prior to SRS (p = 0.04) and an age > 65 years at SRS (p = 0.03) were associated with worse local tumor control. The 5- and 10-year tumor progression-free survival rates were 54.7% and 34.7%, respectively. An age > 65 years at SRS (p = 0.01) was associated with decreased overall survival. The 5- and 10-year overall survival rates were 83% and 70%, respectively.

CONCLUSIONS
SRS appears to be a safe and relatively effective adjuvant management option for intracranial chordomas. The best outcomes were obtained in younger patients without significant neurological deficits. Further well-designed studies are necessary to define the best timing for the use of SRS in the multidisciplinary management of intracranial chordomas.

Authors: Simko Alexander P. , Hudak Mark L. , Han Sabrina H. , Huo Jinhai , Hayward Kelsey , Aldana Philipp R. 
Published: February 2022

OBJECTIVE
The authors’ objective was to compare the actual cost of a regional pediatric neurosurgery telemedicine clinic (PNTMC) with the estimated cost of a traditional physician-staffed outreach clinic.

METHODS
The authors’ PNTMC was a partnership between the University of Florida College of Medicine–Jacksonville and Georgia Children’s Medical Services to service the population of Georgia’s Southeast Health District. Neurosurgeons based in Jacksonville conducted telemedicine visits with patients located at a remote site in Georgia with the assistance of nursing personnel from Children’s Medical Services. The authors determined the actual annual per-patient costs at the Jacksonville and Georgia sites for fiscal years 2018 (FY18) and 2019 (FY19) and estimated the cost of providing traditional physician-staffed outreach clinics.

RESULTS
During FY18 and FY19, the neurosurgery team conducted an average of 24.5 telemedicine patient encounters per year at a cost of $369 per patient visit. The per-patient cost was 32.5% less than the estimated per-patient cost of $547 at a traditional outreach clinic.

CONCLUSIONS
The authors provided neurosurgical telehealth visits to appropriate patients, with a substantial cost savings per patient visit compared with traditional physician-staffed outreach clinics.
