Authors: Metto Elizabeth , Kinuthia Benson N. , Mwita Miriam 
Published: August 2022

The delivery of records management services in businesses is significantly influenced by records management models. However, many colleges don't take into account the implementation models while designing records management programs. In order to provide a model that universities can utilize to execute records management, this study examined the records management methods used by the universities in Kenya. Data was gathered via a questionnaire. The findings shows that the best model that can be proposed to ensure effective management of student records in the academic registrar’s office in Kenyan universities should take cognizance of the differences between public and private universities. In private and new universities, there is no need for standardization of storing records and creation and classification of records. Conversely, there was no need for creation and classification of records, storing records, use of information technology and challenges faced in the management of student records in old and new universities. The challenges faced in the management of student records and retrieval and communication of records should be harmonized between both private and public universities as well old and new universities. Exchange of best practices in these areas should also be undertaken in these areas. Once these areas are addressed, the effective management of students’ records in the universities would be realized.

Abstract. The total demand for and uptake of nutrients by vegetation is rarely quantified or compared across vegetation types. Here, we describe different
nutrient use and allocation strategies in neotropical savanna (cerrado) and transitional forest (cerradão) tree communities composed of
different species, report leaf nutrient resorption and calculate ecosystem-level nutrient use efficiency. We couple net primary productivity (NPP)
estimates with nutrient stoichiometry to quantify nutrient demand and nutrient flows at the whole-stand scale for different components of vegetation
biomass. Species from the two vegetation communities showed similar mean nutrient concentrations and nutrient resorption efficiency, except for wood
P concentration that was fourfold higher in cerrado than cerradão species. The cerradão showed higher canopy NPP, while fine roots and
wood NPP were similar for the two vegetation types. Nutrient requirement in the two vegetation types was dominated by the demands of the canopy,
with canopy resorption generally contributing more than 50 % of the total canopy demand for nutrients, while less than 35 % of N,
P, K, Ca and Mg were allocated to wood or fine roots. Proportionally, cerrado showed higher nutrient demand from
fine roots (over 35 % of the total nutrient demand) and for the wood component (over 13 % of the total nutrient demand), while
∼ 60 %–70 % of the cerradão nutrient demand was allocated to the canopy. The proportional difference in nutrient allocation to the
different biomass components suggests cerrado species allocate less nutrients to a given fine root biomass, but more nutrients to a given wood
biomass. Our findings suggest that cerradão species are more limited in P and K than cerrado species, inducing higher resorption
to compensate for low uptake. Moreover, we found that N uptake for cerradão was higher with lower N use efficiency, i.e. the
amount of production per nutrient unit, leading higher N demand compared to the cerrado. This difference in nutrient dynamics explains how
similar soils and the same climate dominated by savanna vegetation can also support forest-like formations. Tree species composition is likely the
major factor regulating nutrient use, limiting vegetation transitions and influencing nutrient demand at landscape scales.
Stratospheric modulation of Arctic Oscillation extremes as represented by extended-range ensemble forecasts
Authors: Spaeth Jonas , Birner Thomas 
Published: August 2022

Abstract. The Arctic Oscillation (AO) describes a seesaw pattern of variations in atmospheric mass over the polar cap. It is by now well established that the
AO pattern is in part determined by the state of the stratosphere. In particular, sudden stratospheric warmings (SSWs) are known to nudge the
tropospheric circulation toward a more negative phase of the AO, which is associated with a more equatorward-shifted jet and enhanced likelihood for
blocking and cold air outbreaks in mid-latitudes. SSWs are also thought to contribute to the occurrence of extreme AO events. However, statistically
robust results about such extremes are difficult to obtain from observations or meteorological (re-)analyses due to the limited sample size of SSW
events in the observational record (roughly six SSWs per decade). Here we exploit a large set of extended-range ensemble forecasts within the
subseasonal-to-seasonal (S2S) framework to obtain an improved characterization of the modulation of AO extremes due to stratosphere–troposphere
coupling. Specifically, we greatly boost the sample size of stratospheric events by using potential SSWs (p-SSWs), i.e., SSWs that are predicted to
occur in individual forecast ensemble members regardless of whether they actually occurred in the real atmosphere. For example, the S2S ensemble of
the European Centre for Medium-Range Weather Forecasts gives us a total of 6101 p-SSW events for the period 1997–2021. A standard lag-composite analysis around these p-SSWs validates our approach; i.e., the associated composite evolution of stratosphere–troposphere
coupling matches the known evolution based on reanalysis data around real SSW events. Our statistical analyses further reveal that following p-SSWs,
relative to climatology, (1) persistently negative AO states (>1 week duration) are 16 % more likely; (2) the likelihood for extremely
negative AO states (<-3σ) is enhanced by about 40 %–80 %, while that for extremely positive AO states (>+3σ) is
reduced to almost zero; (3) approximately 50 % of extremely negative AO states that follow SSWs may be attributable to the SSW, whereas about
one-quarter of all extremely negative AO states during winter may be attributable to SSWs. A corresponding analysis relative to strong
stratospheric vortex events reveals similar insights into the stratospheric modulation of positive AO extremes. However, conclusions in terms of causality remain difficult, in part due to unconsidered confounding factors.

Published: August 2022

Introduction Gluteus medius tendon tears may not be feasible for direct repair when significant retraction or fatty degeneration is present. Several augmentation techniques have been reported for challenging cases. We describe a novel technique using a transfer of the anterior portion of the gluteus maximus combined with synthetic mesh to reinforce the direct suture of the gluteus medius. The goal of this study was to assess the functional and pain outcomes in three patients treated with this reconstruction technique. Case presentation A retrospective study was performed including 3 patients with complete and retracted ruptures of the abductor mechanism. When conservative management failed, surgical treatment was attempted. After a minimum follow-up of 12 months (mean follow-up of 18 months), all of the patients showed clinical improvement. The mean Harris Hip Score improved from 31.8 to 75.6, with an average postoperative abduction strength of 3 in the Medical Research Council muscle strength grading system, and no residual limp was noticed. The mean Visual Analogue Scale pain score decreased from 8.3 preoperatively to 1.6 postoperatively. No complications were reported. Conclusion In conclusion, this technique demonstrates efficacy in terms of improving clinical symptoms and functional status and is a reproducible way to augment irreparable gluteus medius tears.

Published: August 2022

Background Back pain in young athletes is common. Adolescents are at an increased risk for back pain related to several factors including rapid growth. Traditionally, the conversation around back pain in the adolescent age group has been centered around diagnosis and treatment; however, there are emerging studies regarding prevention. Objective The purpose of the present investigation is to summarize sport-specific risk factors, to describe the growing emphasis on prevention/screening, and report results on minimally invasive and surgical options. Methods The literature search was performed in Mendeley. Search fields were varied until redundant. All articles were screened by title and abstract and a preliminary decision to include an article was made. The full-text screening was performed on the selected articles. Any question regarding the inclusion of an article was discussed by at least 3 authors until an agreement was reached. Results Adolescent athletes have a higher risk of developing spondylolysis and spondylolisthesis than their non-athletic counterparts. Participation in athletic activity alone, increased body mass index, varsity status, and nationally/internationally competitive status are identified are demographic risk factors. Weightlifters, gymnasts, football players, and combat athletes may be at higher risks. Increased lumbar lordosis, abdominal muscle weakness, hip flexor tightness, hamstring tightness, thoracolumbar fascia tightness, femoral anteversion, genu recurvatum, and thoracic kyphosis also predispose. Recent cadaveric and kinematic studies have furthered our understanding of pathoanatomic. There is some evidence to suggest that isokinetic testing and electromyographic data may be able to identify at-risk individuals. Perturbation-based exercise interventions can reduce the incidence of adolescent athletic back pain. There is a large body of evidence to support the efficacy of physical therapy. There is some data to support minimally invasive treatments including external bone growth simulators, steroid injections, and chemonucleolysis for specific pathologies. Endoscopic surgery results for a limited subset of patients with certain disease processes are good. Conclusions Back pain in adolescent athletes is common and may not lead to appropriate alterations in athletes’ level of participation. Athletes with a higher body mass index should be counseled regarding the benefits of losing weight. Isokinetic testing and electromyographic data have the potential as diagnostic and screening tools. Strength deficits and postural control could be used to identify patients requiring early intervention and thus reduce the incidence. External bone growth simulators, steroid injections, and chemonucleolysis could potentially become conservative options in the future. When surgery is indicated, the endoscopic intervention has the potential to decrease operative time, decrease cost, and promote healing.

Background: Autoimmune rheumatic diseases (ARDs) are characterized by immune dysfunction and associated with an increased risk of infections, which were of significant concern during the coronavirus disease 2019 (COVID-19) pandemic. Variable rates of COVID-19 incidence have been reported in patients with ARDs; however, the true effect of this infection on this patient population is still unclear. We, therefore, aimed to evaluate the COVID-19 prevalence among a multiethnic cohort of patients with ARDs in Qatar.
Material and Methods: We used telephonic surveys to collect demographic and clinical information of patients with ARD in Qatar between April 1 and July 31, 2020, including any close contact with a COVID-19 case at home or work and polymerase chain reaction (PCR)-confirmed COVID-19 diagnosis. An electronic medical records review was conducted to verify pertinent data collected through the surveys. Prevalence with 95% confidence interval (CI), Student's t-tests, and chi-square/Fisher's exact tests were used for univariate analyses, whereas multivariate logistic regression was used to identify factors associated with COVID-19.
Results: The study included 700 patients with ARD (mean age, 43.2 ± 12.3 years), and 73% were female. Until July 2020, 75 (11%, 95% CI 9%–13%) patients had COVID-19. Factors associated with COVID-19 included being a man (adjusted odds ratio [aOR] 2.56, 95% CI 1.35–4.88, p = 0.01) and having close contact with a COVID-19 case (aOR 27.89, 95% CI 14.85–52.38, p = 0.01). Disease severity and rheumatic medications had no significant association with the odds of contracting COVID-19. In the 86 patients with ARD having close contact, the frequency of hydroxychloroquine utilization was lower in patients who contracted COVID-19 than in those who did not (35% vs 72.5%, p = 0.01).
Conclusions: In Qatar, patients with ARDs had an overall higher prevalence of COVID-19 than global estimates. Being male and having close contact with a COVID-19 case were strongly associated with COVID-19 as reported globally. The presence of comorbid conditions, disease-specific factors, and rheumatic medications had no significant effect on the risk of COVID-19 in our study suggesting alternative mechanisms to the increased prevalence.

The aim of the study is to describe the awareness about the vaccination in patients with chronic kidney disease on haemodialysis and to estimate the vaccination status received in these patients on dialysis. Methods: It is a cross sectional study conducted in 83 patients diagnosed to have chronic kidney disease undergoing dialysis for at least 1 month. Demographic characteristics and comorbidity data (as self-reported) were collected and questionnaire assessment was filled about the vaccination and counselling received. Results: The prevalence of CKD were 73.5% in males and 26.5% in females with a mean age of 48.9 years. Among the different occupations of the patient with no job/housewife was 56.6% while professional jobs were 18.1% business and non-professional source were 13.3% and agriculture related was 12.0%. Evaluation of education stated that patients educated with higher schooling had 15.6% of prevalence of CKD compared to degree holders and Masters. The different comorbidities among the studied patients were Hypertension- 84.3%, Diabetes- 47%, Stroke- 12%, Connective tissue disorder- 18.1% and COPD- 44.6%.

Published: August 2022

Background: Type 1 diabetes mellitus (T1DM) is a chronic, immune-mediated disease characterized by the destruction of insulin-producing β cells in the pancreas. This study investigated the influence of single nucleotide polymorphisms (SNP) in tumor necrosis factor (TNF-α) –308 G/A (rs1800629,) on T1DM patients. Method: The study was included 75 T1DM patients and 25 healthy subjects. The SNP–308 G/A TNF-α gene was detected by using polymerase chain reaction restriction fragment length polymorphism (RFLP-PCR) technique in T1DM patients and controls. Results: The genotype distribution results of the -308G/A SNP of Tumor Necrosis Factor - α (TNF- α)-308 G/A gene showed significant difference (p<0.05) between controls (GG: n= 24, 96%; GA: n=1, 4%; AA: n=0, 0%) and T1DM patients (GG: n= 44, 58.67%; GA: n=21, 28%; AA: n=10, 13.33%).These results showed an increased in GA, AA genotype and G allele of the TNF- α(-308) G/A in T1DM patients than controls, and they were significantly more likely than controls to have the mutant allele (OR=18.431, 95%CI= 2.464-137.855, p=0.00001). These results indicate a possible role for the G genotype in T1DM disease.

Abdominal massage and heat application are prevalent non pharmacological interventions for reliving high gastric residual volume, abdominal distension and other some gastro intestinal functioning. It helps to boost the nutritional transition through the gastro intestinal tract, induces peristaltic movement, and consequently lowers the intra abdominal pressure. Moreover, it has been shown to be safe, effective, no pharmacological and non-invasive methods with no side effects. The aim of the study was to determine the effectiveness of multi interventional components on gastric residual volume, abdominal distension and gastro intestinal functioning among patients with nasogastric tube feeding admitted in Intensive Care Units. Subjects: patients who are admitted in the ICU and have nasogastric tube for feeding during the period of data collection. They are divided randomly (cover slip method) in to four groups of 15 in each group (three experimental groups and one control group).Setting: The study was conducted in the ICU’s of selected hospital .Results: gastric residual volume, abdominal distension and gastro intestinal functioning were analysed for 4 groups and statistical significant improvement were found among the study groups than their control group. The frequency of vomiting episode was significantly reduced among study groups than the control group.

Abstract
The Round Mountain mine in Nevada is one of the world’s largest volcanic-hosted precious metal deposits and has been commercially operated since 1976. The deposit is hosted by a thick sequence of Oligocene ash-flow tuffs and volcaniclastic rocks overlying a pre-Tertiary basement. Gold mineralization largely occurs as disseminated electrum in association with quartz, adularia, illite, smectite, pyrite, silver sulfosalts, manganese oxide, and iron oxides, with minor alunite, fluorite, and realgar in the upper portion of the deposit. The deposit was extensively oxidized during a period of Basin and Range faulting approximately 9 to 16 Ma. Multiple phases of geochemical characterization have been undertaken as part of project development, including over 740 acid-base accounting analyses and 38 humidity-cell tests operated for up to 193 weeks. These tests demonstrate that the Round Mountain host rock contains very little sulfide mineralization and show a low potential for acid generation and metal(loid) release. Where sulfide minerals are present, they are frequently partially or entirely encapsulated in nonreactive silicates or are present as coarse euhedral to subhedral pyrite grains that require more energy to oxidize compared to finer grained anhedral crystals. As such, there is likely to be a significant lag time to acid generation, and it is possible that acidic conditions may never develop under field conditions due to the combined effects of stable pyrite petrology and encapsulation, plus the lower leaching rates that would occur in the arid desert conditions in the field versus the laboratory. This prediction is supported by empirical field observations that indicate during the 40-yr period of operation there has been no acid generation associated with the waste-rock facilities. The multiple phases of geochemical characterization have been used to define procedures for operational waste-rock classification, segregation, and management at the Round Mountain mine based on lithology and oxidation.

Os órgãos de controle interno na administração pública municipal funcionam como um instrumento estratégico no combate à corrupção. Por não existir uma metodologia que estabeleça a criação e funcionamento dos órgãos de controladoria nos municípios, cada entidade pública é livre para caracterizar da maneira que convém ao gestor. Este estudo buscou analisar as características que compõem os sistemas de controladoria nos municípios da zona da mata norte pernambucana. Para tanto, investigou os atributos das controladorias nos municípios, examinou as funções de controladoria desempenhadas pelos órgãos de controle municipal, identificou as práticas adotadas pelas controladorias e propôs formas de ampliação e melhoria das ações. Mediante metodologia aplicada, a pesquisa tem um caráter exploratório e descritivo, delimitando as particularidades das controladorias, identificando suas funções atividades através de aplicação de questionários aos gestores dos órgãos de controle interno nos municípios. Para auxiliar no entendimento dos resultados encontrados, uma entrevista semiestruturada foi realizada com dois participantes. Por meio dos resultados obtidos foi possível identificar a ausência de parâmetros para atuação desses órgãos, tanto nas suas funções, quanto nas exigências de qualificação e definição de servidores atuantes no setor. Por meio das entrevistas, foi identificado um conflito de interesse entre o objetivo de controle e o vínculo do cargo responsável pelo setor. Por fim, levanta-se pontos importantes sobre a necessidade de mudança nas estruturas dos órgãos de controle interno na administração pública brasileira.
