Sows' responses to increased heat load - A review.

There is a comprehensive body of literature on how increased air temperature affects the physiology, production and behaviour of sows, while very few studies consider the thermal effects of air humidity and air velocity. This review summarises studies that have investigated effects of air temperature by reviewing published literature in which sows were exposed to at least two different levels of air temperature ranging from 15 °C to 39 °C. Increased rectal temperature was investigated in the majority of the studies (26) and on average, the rectal temperature increased by 0.099 °C per °C increased air temperature above 25 °C. The increase was smaller at lower air temperatures, and it was suggested that rectal temperature is practically unaffected by air temperatures in the range of 15 °C-21 °C. This review elucidates how air temperature also affects performance indicators such as respiration rate, vaginal temperature, skin temperature, feed intake, milk yield, body weight loss during lactation, mortality, litter daily weight gain during lactation and sow behaviour. One study reported how respiration rate, rectal temperature, vaginal temperature and skin temperature were affected by both air temperature and air humidity, and the results suggest that the relative significance of air temperature and humidity may be similar for sows and finishing pigs (e.g. an increase of 40% relative humidity at an air temperature of 30 °C has a similar effect as a 1.9 °C increase in temperature). Studies on mitigation methods against the effects of high temperature and humidity such as snout cooling, drip cooling and floor cooling were reviewed to extract knowledge related to the effects of air velocity, temperatures of surrounding surfaces and the opportunity for sows to moisten their skin.

Hip-fracture osteosynthesis training: exploring learning curves and setting proficiency standards.

Background and purpose - Orthopedic surgeons must be able to perform internal fixation of proximal femoral fractures early in their career, but inexperienced trainees prolong surgery and cause increased reoperation rates. Simulation-based virtual reality (VR) training has been proposed to overcome the initial steep part of the learning curve but it is unknown how much simulation training is necessary before trainees can progress to supervised surgery on patients. We determined characteristics of learning curves for novices and experts and a pass/fail mastery-learning standard for junior trainees was established. Methods - 38 first-year residents and 8 consultants specialized in orthopedic trauma surgery performed cannulated screws, Hansson pins, and sliding hip screw on the Swemac TraumaVision VR simulator. A previously validated test was used. The participants repeated the procedures until they reached their learning plateau. Results - The novices and the experts reached their learning plateau after an average of 169 minutes (95% CI 152-87) and 143 minutes (CI 109-177), respectively. Highest achieved scores were 92% (CI 91-93) for novices and 96% (CI 94-97) for experts. Plateau score, defined as the average of the 4 last scores, was 85% (CI 82-87) and 92% (CI 89-96) for the novices and the experts, respectively. Interpretation - Training time to reach plateau varied widely and it is paramount that simulation-based training continues to a predefined standard instead of ending after a fixed number of attempts or amount of time. A score of 92% comparable to the experts' plateau score could be used as a mastery learning pass/fail standard.

Virtual-reality simulation to assess performance in hip fracture surgery.

BACKGROUND AND PURPOSE: Internal fixation of hip fractures is a common and important procedure that orthopedic surgeons must master early in their career. Virtual-reality training could improve initial skills, and a simulation-based test would make it possible to ensure basic competency of junior surgeons before they proceed to supervised practice on patients. The aim of this study was to develop a reliable and valid test with credible pass/fail standards. METHODS: 20 physicians (10 untrained novices and 10 experienced orthopedic surgeons) each performed 3 internal fixation procedures of an undisplaced femoral neck fracture: 2 hook-pins, 2 screws, and a sliding hip screw. All procedures were preformed on a trauma simulator. Performance scores for each procedure were obtained from the predefined metrics of the simulator. The inter-case reliability of the simulator metrics was explored by calculation of intra-class correlation coefficient. Validity was explored by comparison between novices' and experts' scores using independent-samples t-test. A pass/fail standard was set by the contrasting-groups method and the consequences were explored. RESULTS: The percentage of maximum combined score (PM score) showed an inter-case reliability of 0.83 (95% CI: 0.65-0.93) between the 3 procedures. The mean PM score was 30% (CI: 7-53) for the novices and 76% (CI: 68-83) for the experienced surgeons. The pass/fail standard was set at 58%, resulting in none of the novices passing the test and a single experienced surgeon failing the test. INTERPRETATION: The simulation-based test was reliable and valid in our setting, and the pass/fail standard could discriminate between novices and experienced surgeons. Potentially, training and testing of future junior surgeons on a virtual-reality simulator could ensure basic competency before proceeding to supervised practice on patients.

Intakes of calcium, vitamin D, and dairy servings and dental plaque in older Danish adults.

BACKGROUND: To investigate whether intakes of calcium and dairy-servings within-recommendations were associated with plaque score when allowing for vitamin D intakes. METHODS: In this cross-sectional study, including 606 older Danish adults, total dietary calcium intake (mg/day) was classified as below vs. within-recommendations and dairy intake as <3 vs. ≥3 servings/ d. Dental plaque, defined as the percentage of tooth surfaces exhibiting plaque, was classified as < median vs. ≥median value (9.5%). Analyses were stratified by lower and higher (≥6.8 µg/d) vitamin D intake. FINDINGS: Intakes of calcium (OR = 0.53; 95% CI = 0.31-0.92) and dairy servings (OR = 0.54; 95% CI = 0.33-0.89) within-recommendations were significantly associated with lower plaque score after adjustments for age, gender, education, intakes of alcohol, sucrose and mineral supplements, smoking, diseases, number of teeth, visits to the dentist, use of dental floss/tooth pick and salivary flow, among those with higher, but not lower, vitamin D intake. CONCLUSION: Intakes of calcium dairy-servings within-recommendations were inversely associated with plaque, among those with higher, but not lower, vitamin D intakes. Due to the cross-sectional nature of the study, it is not possible to infer that this association is causal.

Findings from the oral health study of the Danish Health Examination Survey 2007-2008.

OBJECTIVE: The aims of the oral part of the Danish Health Examination Survey (DANHES 2007-2008) were (1) to establish an oral health database for adult Danes and (2) to explore the influence of general diseases and lifestyle on oral health. This paper presents the study population, examination methods, questionnaire and baseline results. MATERIALS AND METHODS: The study population comprised 4402 subjects, aged 18-96, consecutively enrolled from 18 065 DANHES participants from 13 municipalities in Denmark. The oral part consisted of a validated questionnaire and a clinical examination, carried out in mobile units by three trained and calibrated dental hygienists. The data were processed with descriptive statistics and mono- and bivariate analyses. RESULTS: The mean age was 54.1 years and 60% were women. The mean number of natural teeth was 26.6; the mean DMFT/DMFS values were 18.9 and 61.0, and varied with age (DMFT 8.7-24.3). A higher proportion of females suffered from dental erosion in the younger age groups. Forty per cent of all subjects had a mean clinical attachment loss ≥ 3 mm, varying from 4% among those aged 18-34 to 80% in those over 75. A sub-optimal saliva secretion rate was more common among females than males (17.7% vs 10.4%) and this was reflected by the reported frequency of dry mouth. CONCLUSION: This extensive cross-sectional study provides a platform for obtaining future knowledge of the impact of health- and lifestyle-related factors on oral diseases. The validated questionnaire and the clinical characteristics enable robust analyses, although the conclusions may be hampered by limited external validity.

Daytime and scheduled surgery for major dysvascular lower extremity amputation.

INTRODUCTION: Patients undergoing a major dysvascular lower extremity amputation (LEA) often have a poor outcome with a high risk of complications and mortality despite improvements in care and perioperative programmes. We evaluated whether scheduled surgery would reduce the failure rate in patients with a major LEA. METHODS: A total of 328 consecutive patients undergoing a major LEA from 2016 to 2019 were enrolled at a single centre. Early failure was defined as re-amputation or revision within 30 days of the index amputation. In 2018, a new regime comprising two scheduled surgery days was implemented. The risk of failure comparing the two cohorts (2016-2017, n = 165 versus 2018-2019, n = 163) was calculated for amputation on scheduled versus non-scheduled days and for other potentially influencing factors. RESULTS: The median (25-75% quartiles) age of all patients was 74 (66-83) years, 91% had an American Society of Anesthesiologists (ASA) grade ≥ 3 and 92% had atherosclerosis or diabetes mellitus. The index amputee levels were 36% below-knee, 60% transfemoral and 4% bilateral transfemoral. In the intervention cohort, 59% were amputated on the scheduled days versus 36% in the control group (p less-than 0.001). Correspondingly, more patients (72.4% versus 57.6%, p = 0.005) were amputated during daytime and the 30-day failure rate was reduced to 11.0% (n = 18) versus 16.4% (n = 27) (p = 0.2). Risk of failure on scheduled days in the intervention group was 8.3% versus 14.9% on any other day (p = 0.2). Correspondingly, daytime surgery reduced the risk of failure (6.8% versus 22.2%, p = 0.005). CONCLUSION: Daytime and scheduled surgery for major LEA may possibly reduce early risk of failure. FUNDING: none. TRIAL REGISTRATION: not relevant.

Prediction of odor from pig production based on chemical odorants.

The present work was performed to investigate the use of odorant measurements for prediction of odor concentration in facilities with growing-finishing pigs and to analyze the odorant composition in facilities with different floor and ventilation systems. Air was sampled in Nalophan bags, odor concentrations were measured by dilution-to-threshold olfactometry, and concentrations of odorants were measured by proton-transfer-reaction mass spectrometry (PTR-MS). Olfactometry and chemical analyses were synchronized to take place at identical time intervals after sampling. A principal component analysis revealed that different facilities for growing-finishing pigs can be distinguished based on the odorants. Pit ventilation comprising a small amount of the total ventilation air (10-20%) in facilities with both room and pit ventilation can be used to concentrate odorants, whereas the room ventilation contains lower concentrations of most odorants. A partial least squares regression model demonstrated that prediction of the odor concentration based on odorants measured by PTR-MS is feasible. Hydrogen sulfide, methanethiol, trimethylamine, and 4-methylphenol were identified as the compounds having the largest influence on the prediction of odor concentration, whereas carboxylic acids had no significant influence. In conclusion, chemical measurement of odorants by PTR-MS is an alternative for expressing the odor concentration in facilities with growing-finishing pigs that can be used to increase the understanding of odor from different types of facilities and improve the development of odor reduction technologies.

Indicators for root caries in Danish persons with recently diagnosed Alzheimer's disease.

OBJECTIVE: To identify indicators of root caries among persons with newly diagnosed Alzheimer's disease (AD). BACKGROUND: Few studies have investigated dental caries in older adults with AD. Previously we found that persons with AD had significantly more root caries compared to persons with dementia other than AD. METHODS: Participants were recruited from two university hospital clinics in Copenhagen, Denmark. A team of neurologists/geriatricians carried out the diagnostic screening. The study included an interview, oral examination and medical records. RESULTS: We evaluated potential indicators of root decay across subjects with 3+ decayed surfaces vs. <3 decayed surfaces. Variables associated with increased odds of root caries were age over 80 years, 2+ decayed coronal surfaces and 5+ filled root surfaces. Among the social variables, living with someone was associated with a nearly 70% reduction in the odds of having 3+ surfaces of untreated caries. DISCUSSION: Root caries is highly prevalent among individuals with new AD and there is still a strong need for active assessment of and attention to oral problems in persons with AD. Our findings document that recently diagnosed AD cases with multiple coronal caries lesions are at elevated risk of having more root caries. Also persons 81+ years and those with multiple root fillings are more likely to have numerous untreated root lesions.

Amount and type of alcohol consumption and missing teeth among community-dwelling older adults: findings from the Copenhagen Oral Health Senior study.

OBJECTIVES: To study if an association between total weekly intake of alcohol, type-specific weekly alcohol intake, alcoholic beverage preference, and the number of teeth among older people exists. METHODS: A cross-sectional study including a total of 783 community-dwelling men and women aged 65-95 years who were interviewed about alcohol drinking habits and underwent a clinical oral and dental examination. Multiple regression analyses were applied for studying the association between total weekly alcohol consumption, beverage-specific alcohol consumption, beverage preference (defined as the highest intake of one beverage type compared with two other types), and the number of remaining teeth (≤ 20 versus >20 remaining teeth). RESULTS: The odds ratio (OR) of having a low number of teeth decreased with the total intake of alcohol in women, with ORs for a low number of teeth of 0.40 [95 percent confidence interval (CI) 0.22-0.76] in women drinking 1-14 drinks per week and 0.34 (95 percent CI 0.16-0.74) in women with an intake of more than 14 drinks per week compared with abstainers. Similar relations could also be obtained for type-specific alcohol intake of wine and for wine and spirits preference among women. Men who preferred beer showed a decreased risk for a low number of teeth compared with men with other alcohol preferences. CONCLUSION: In this study, alcohol consumption, wine drinking, and wine and spirits preference among women were associated with a higher number of teeth compared with abstainers. Among men, those who preferred beer also had a higher number of teeth.

The Copenhagen Oral Health Senior Cohort: design, population and dental health.

BACKGROUND: In order to study the way old age influence oral health, the Copenhagen Oral Health Senior Cohort (COHS) has been established. OBJECTIVES: To describe the design, measurement procedures, and baseline values for COHS including spatial distribution of restorations and dental caries as well as reasons for non-participation. MATERIALS AND METHODS: Seven hundred and eighty-three individuals aged 65 years or older, from a total of 1918 invited elderly people, underwent an interview regarding oral health-related behaviour and a clinical oral examination including measurement of unstimulated whole saliva flow rate. RESULTS: Twelve percent of the COHS was edentulous. The number of dental restorations was higher for women compared to men; however, men had more caries than women. Coronal caries was most frequent on mesial and distal surfaces and on the maxillary incisors and canines; root caries was most frequent on labial surfaces and evenly distributed within the dentition. Only 41% of all invited elderly people accepted the invitation, with old age and poor health being the primary reasons for non-participation. CONCLUSION: The baseline values for COHS show that a substantial proportion of the participants had retained a natural dentition and that dental caries was prevalent with the anterior maxillary teeth being most affected.

The overtime effect of social position on dental caries experience in a group of old-aged Danes born in 1914.

OBJECTIVES: The purpose of this study was to analyze the life-course effects of education, occupation, and income at ages 70, 75, 80, and 85 years, respectively, on dental caries experience of 85-year-olds. METHODS: The present study includes follow-up data from a population-based study, which comprised a sample of 176 individuals aged 85 years. Data on social position were collected at ages 70, 75, 80, and 85 years by means of structured personal interviews. Clinical oral health examinations were conducted to obtain data on dental caries at age 85. Dental caries was recorded at tooth surface level and caries experience was expressed by the DMF Index: the decayed tooth surfaces (D component), missing tooth surfaces (M component), and filled tooth surfaces (F component). RESULTS: The participants in the present study demonstrated a high level of dental caries experience; the prevalence rate for active dental caries (D-S) was 80 percent. Older adults with low education, low occupational status, and poor income tended to have more active dental caries compared to their counterparts. In contrast, individuals with high education (F-S = 35.5) and high occupational status (F-S = 36.0) had significantly more filled surfaces than persons with low education (F-S = 24.0) and low occupational status (F-S = 25.6). Individuals with high income at ages 75, 80, and 85 years had more filled surfaces (F-S = 31.9, 33.2, 34.1) compared to persons with low income (F-S = 25.5, 23.5, 22.8). CONCLUSION: The study identified social inequalities across age among the very old individuals in relation to dental caries experience.

Midlife Cognitive Ability, Education, and Tooth Loss in Older Danes.

OBJECTIVE: To examine the possible influence of cognitive ability and education at age 50 or 60 on number of teeth at age 70. SETTING: Community-dwelling population in Copenhagen, Denmark. PARTICIPANTS: Men and women born in 1914 (N = 302). MEASUREMENTS: Cognitive ability was assessed using the Wechsler Adult Intelligence Scale at age 50 or 60. A global cognitive ability measure was used as a continuous measure and according to tertile. Information on education was gathered using a questionnaire at age 50 or 60. A clinical oral examination took place at age 70, and oral health was measured according to number of teeth (<6 vs ≥6). Baseline covariates were smoking, alcohol, sex, and income. RESULTS: Logistic regression analyses revealed that greater cognitive ability and educational attainment had a protective effect against risk of tooth loss. The associations were significant and persisted after adjusting for confounders and a two-way interaction between cognitive ability and education. CONCLUSION: Higher education level and cognitive ability measured at age 50 or 60 were associated with having more teeth at age 70. Whether these findings are due to the interaction of these factors with oral health, related socioeconomic factors, or other factors remains to be studied.

An open-label, parallel group study investigating the effects of age and gender on the pharmacokinetics of the once-daily glucagon-like peptide-1 analogue liraglutide.

Liraglutide is a once-daily glucagon-like peptide-1 analogue being developed for the treatment of type 2 diabetes. The aim of this study was to investigate the effect of age and gender on the pharmacokinetics of liraglutide. Eight male and 8 female subjects were recruited from an 18- to 45-year-old group and an over-65-year-old group, respectively. All subjects received a single subcutaneous dose of 1.0 mg liraglutide. The area under the liraglutide plasma concentration curve from time 0 to last quantifiable concentration adjusted for body weight (significant covariate; P = .001) was found to be equivalent in young and elderly subjects (primary end point), with an estimated ratio of 0.94 (90% confidence interval, 0.84-1.06; P = .39). No significant impact of gender was observed (P = .38; estimated ratio, 1.08; 90% confidence interval, 0.93-1.26). Adverse events were of mild or moderate severity. The most frequently reported events were headache, vomiting, and nausea. When adjusted for body weight, no effect of gender or age was found on the pharmacokinetics of liraglutide.

Dental caries, periodontal disease, and cardiac arrhythmias in community-dwelling older persons aged 80 and older: is there a link?

OBJECTIVES: To examine whether caries or periodontitis is associated with cardiac arrhythmias in community-dwelling people aged 80 and older. SETTING: Urban, community-based population in Stockholm, Sweden. DESIGN: Cross-sectional. PARTICIPANTS: Eligible persons were identified through the Kungsholmen Project, which is an ongoing, longitudinal, population-based study of the oldest old. The present study included 125 dentate individuals. MEASUREMENTS: Data from interviews, a medical examination, and an oral examination. The assessment of cardiac arrhythmia was based on a clinical examination by a physician or the Stockholm Inpatient Register. Active root caries, active coronal caries, and periodontitis were assessed using previously defined National Institute of Dental and Craniofacial Research diagnostic criteria. RESULTS: The primary finding of the multivariate logistic regression analysis was that persons with three or more active root caries lesions had more than twice the odds of cardiac arrhythmias than persons without active root caries. The results did not notably change after adjusting for age, medications that reduce saliva, and number of teeth. Persons with one to two active coronal caries lesions had 2.8 times higher odds (95% confidence interval=1.1-7.0) of arrhythmia than persons without active coronal caries, but there was no greater risk for persons with three or more coronal caries lesions. There was no association between periodontal disease and arrhythmia. CONCLUSION: The findings indicate that there may be a link between active root caries and cardiac arrhythmias in the oldest old. Nevertheless, although a biological pathway is not obvious, it is plausible that both are simply markers of declining general health. The results suggest the need for further study of these relationships.

The strength of two indicators of social position on oral health among persons over the age of 80 years.

OBJECTIVE: The objective of the present study is to analyze how two dimensions of social position, education and social class, are associated with oral health among generally healthy, community-dwelling persons over the age of 80 years. METHODS: The present investigation is based on a sample of 157 community-dwelling individuals from The Kungsholmen Elders Oral Health Study (KEOHS) and included data from interviews and oral examinations. Social position was measured by education and social class. Oral health was measured by active coronal caries, active root caries, edentulism and use of dental services. RESULTS: The primary findings of the adjusted multivariate logistic regression analysis were that, compared to persons who had been in higher positions, persons who had been blue-collar/ white-collar workers had significantly greater odds of having coronal caries and high, but nonsignificant odds of being edentulous. Further, persons with elementary/ medium education tended to forego regular dental services more than persons with high education. CONCLUSION: The study identified social inequalities in oral health even in a population of independently living, generally healthy very old Swedes and in a country where the public health policies have tried to minimize these inequalities.

Dental care for aging populations in Denmark, Sweden, Norway, United kingdom, and Germany.

This article reviews access to and financing of dental care for aging populations in selected nations in Europe. Old age per se does not seem to be a major factor in determining the use of dental services. Dentition status, on the other hand, is a major determinant of dental attendance. In addition to perceived need, a variety of social and behavioral factors as well as general health factors have been identified as determinants of dental service use. Frail and functionally dependent elderly have special difficulties in accessing dental care; private dental practitioners are hesitant to provide dental care to these patients. One reason may be that the fee for treating these patients is too low, considering high dental office expenses. Another reason may be problems related to management of medically compromised patients. This raises an important question: does inadequate training in geriatric dentistry discourage dentists from seeking opportunities to treat geriatric patients? Overall, the availability of dental services, the organization of the dental health care delivery system, and price subsidy for dental treatment are important factors influencing access to dental care among older people in Europe as well as in the United States.

Social relations as determinants of oral health among persons over the age of 80 years.

OBJECTIVE: To analyze whether social relations during a 7-year follow-up influence oral health among generally healthy, community-dwelling persons over the age of 80 years. METHOD: The present investigation is based on a subsample of 129 dentate community-dwelling individuals from The Kungsholmen Elders Oral Health Study (KEOHS), which included data from interviews and oral examinations. Social relations were measured in terms of marital status, living alone, frequency of contacts, number of confidants, and satisfaction with social contacts and with the frequency of contacts. Oral health was measured in terms of coronal caries and root caries. RESULTS: The primary findings of the adjusted multivariate logistic regression analysis were that persons who lived alone or who became alone during the 7 years prior to the dental examination had greater odds of having coronal caries (odds ratio (OR): 2.4, 95% CI: 1.0-5.7) than those who continually lived with others, and that persons who were continuously dissatisfied with the frequency of their social contacts were more likely to have root caries than those who reported a sustained satisfaction with the frequency of their social contacts (OR: 2.9, 95% CI: 1.2-7.2). CONCLUSION: This study suggests that social relations are related to the oral health status of old-old individuals. From a psychosocial perspective, our findings contribute to a deeper understanding of the background of oral health status in older adults.

Dental caries in persons over the age of 80 living in Kungsholmen, Sweden: findings from the KEOHS project.

OBJECTIVES: The Kungsholmen Elders Oral Health Study (KEOHS) evaluated the oral health status of generally healthy, community-dwelling persons over the age of 80 living in Kungsholmen, an area in central Stockholm. This paper reports findings regarding the prevalence and severity of dental caries among the dentate participants. BASIC RESEARCH DESIGN: Caries examinations were conducted on eligible persons participating in the Kungsholmen Project, an ongoing, longitudinal study of older adults. SETTING: Caries examinations were carried out between 1994 and 1996 at two local clinics by three standardised examiners using defined visual, tactile criteria. PARTICIPANTS: Among 296 potentially eligible participants, 159 were examined, and a total of 129 had at least one tooth. MAIN OUTCOME MEASURES: The caries examination identified decayed and filled surfaces and missing teeth. RESULTS: Of the dentate subjects examined, 80% had teeth in both arches; 98% had at least one coronal filling; 81% had one or more restored root surfaces. Depending upon age and gender, between 36% and 56% of those examined had untreated coronal caries, and between 54% and 75% had untreated root caries. CONCLUSIONS: These findings document the substantial and ongoing impact of dental caries in a sample of generally healthy, community-dwelling older adults and underscore the importance of continued caries prevention and treatment in the aged.

Smoking and drinking as risk indicators for tooth loss in middle-aged Danes.

OBJECTIVES: To investigate tobacco and alcohol consumption as risk indicators for missing teeth in late middle-aged Danes. METHOD: In all, 1,517 Copenhagen Aging and Midlife Biobank (CAMB) participants received a clinical oral examination that included number of teeth. Information on smoking, drinking, and various covariates was obtained using self-administered, structured questionnaires. Descriptive statistics and logistic regression (dependent variable: 6+ vs. <6 missing teeth) were used to investigate smoking and drinking in relation to missing teeth. RESULTS: Current smokers, persons who currently or previously smoked >15 tobacco units/day, and persons who had smoked for 27+ years had elevated mean scores of missing teeth and associated odds ratios (OR) compared with never smokers. Relative to nondrinkers, alcohol consumption was associated with reduced odds of missing 6+ teeth. DISCUSSION: Our findings suggest that smoking is positively associated, while alcoholic beverage consumption is inversely related to tooth loss in middle-aged Danes.

Non-destructive Faraday imaging of dynamically controlled ultracold atoms.

We describe an easily implementable method for non-destructive measurements of ultracold atomic clouds based on dark field imaging of spatially resolved Faraday rotation. The signal-to-noise ratio is analyzed theoretically and, in the absence of experimental imperfections, the sensitivity limit is found to be identical to other conventional dispersive imaging techniques. The dependence on laser detuning, atomic density, and temperature is characterized in a detailed comparison with theory. Due to low destructiveness, spatially resolved images of the same cloud can be acquired up to 2000 times. The technique is applied to avoid the effect of shot-to-shot fluctuations in atom number calibration, to demonstrate single-run vector magnetic field imaging and single-run spatial imaging of the system's dynamic behavior. This demonstrates that the method is a useful tool for the characterization of static and dynamically changing properties of ultracold atomic clouds.
